技术领域technical field
本实用新型涉及单相电容运转电动机技术领域，更具体地说，涉及一种单相电容运转电动机的接线结构。The utility model relates to the technical field of a single-phase capacitor running motor, in particular to a wiring structure of a single-phase capacitor running motor.
背景技术Background technique
为满足不同的使用需求，单相电容运转电动机一般都采用多档位调速。目前行业内使用的单相电容运转电动机主要有T型和L型两种接法，具体参见图1和图2。采用T型接法时，主绕组设置有绕组抽头SH1、绕组抽头H1、绕组抽头M1和绕组抽头L1，电源线连接在不同的绕组抽头，电动机运行在不同的档位。但是T型对于多档位容易感应电压超标，原因是感应电压限制是基于T型高档运行，当调速绕组受到反电势冲击时，高档与低档转差率越大，调速绕组匝数越多，感应电压就越高，从而产生的冲击越大，导致感应电压超标。采用L型接法时，副绕组设置有绕组抽头SH2、绕组抽头H2、绕组抽头M2和绕组抽头L2，电源线连接在不同的绕组抽头，电动机运行在不同的档位。但是，L型对于多档位容易出现电容端电压超标，由于电容端电压超过了电容器的标称电压，因此，缩短了电容器的使用寿命。In order to meet different usage requirements, single-phase capacitor running motors generally adopt multi-gear speed regulation. At present, there are mainly two connection methods of single-phase capacitor running motors used in the industry, T-type and L-type, see Figure 1 and Figure 2 for details. When the T-type connection is adopted, the main winding is provided with winding taps SH1, winding taps H1, winding taps M1 and winding taps L1, the power lines are connected to different winding taps, and the motor runs in different gears. But the T-type is easy to induce voltage exceeding the standard for multiple gears. The reason is that the induction voltage limit is based on the high-end operation of the T-type. When the speed regulating winding is impacted by the back EMF, the greater the slip between high and low gears, the more the number of turns of the speed regulating winding. , the higher the induced voltage is, the greater the impact will be, causing the induced voltage to exceed the standard. When the L-type connection is adopted, the auxiliary winding is provided with winding taps SH2, winding taps H2, winding taps M2 and winding taps L2, the power lines are connected to different winding taps, and the motor runs in different gears. However, the L-type is prone to excessive capacitor terminal voltage for multiple gears. Since the capacitor terminal voltage exceeds the nominal voltage of the capacitor, the service life of the capacitor is shortened.
综上可以看出，如何提供一种单相电容运转电动机的接线结构减少感应电压超标、电容端电压超标情况的发生是本领域技术人员亟待解决的技术问题。In summary, it can be seen that how to provide a wiring structure for a single-phase capacitor-operated motor to reduce the occurrence of excessive induced voltage and capacitor terminal voltage is a technical problem to be solved urgently by those skilled in the art.

Inside the winding group, compared with the T-type and L-type connection methods, the number of turns of the main winding group of the utility model as the working winding is reduced, and the magnetomotive force of the winding is reduced, which in turn leads to less electromagnetic induction of the secondary winding group, that is, the capacitor terminal The voltage decreases; at the same time, when the single-phase capacitor running motor is in high-grade operation, the number of turns of the induction winding is smaller than the number of turns of the T-type induction winding, that is, the induction voltage decreases accordingly.

具体实施方式Detailed ways
下面将结合本实用新型实施例中的附图，对本实用新型实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本实用新型一部分实施例，而不是全部的实施例。基于本实用新型中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本实用新型保护的范围。The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.
本实用新型公开了一种单相电容运转电动机的接线结构，以解决单相电容运转电动机电压超标、电容端电压超标的问题。The utility model discloses a wiring structure of a single-phase capacitor running motor to solve the problems that the voltage of the single-phase capacitor running motor exceeds the standard and the capacitor terminal voltage exceeds the standard.
参见图3，本实用新型实施例公开的一种单相电容运转电动机的H型接线电路图，包括：主绕组组M、副绕组组A和电容C，主绕组组M的一端和副绕组组A的一端连接且成90°相位角；Referring to Fig. 3 , the H-type wiring circuit diagram of a single-phase capacitor running motor disclosed by the embodiment of the utility model includes: the main winding group M, the secondary winding group A and the capacitor C, one end of the main winding group M and the secondary winding group A One end of the connection and form a 90° phase angle;
其中：in:
主绕组组M包括第一主绕组M1和第二主绕组M2，第一主绕组M1和第二主绕组M2串联连接。The main winding group M includes a first main winding M1 and a second main winding M2, and the first main winding M1 and the second main winding M2 are connected in series.
副绕组组A包括多个串联连接的副绕组，且副绕组组12设置有多个绕组抽头。The secondary winding group A includes a plurality of secondary windings connected in series, and the secondary winding group 12 is provided with a plurality of winding taps.
举例说明，在图3中，副绕组组A包括第一副绕组A1、第二副绕组A2和第三副绕组A3，第一副绕组A1、第二副绕组A2和第三副绕组A3串联连接。For example, in Fig. 3, the secondary winding group A includes the first secondary winding A1, the second secondary winding A2 and the third secondary winding A3, and the first secondary winding A1, the second secondary winding A2 and the third secondary winding A3 are connected in series .
副绕组组A设置有绕组抽头SH、绕组抽头H、绕组抽头M和绕组抽头L，电源线连接在不同的绕组抽头表示电动机运行在不同的档位。电源线连接在绕组抽头SH时，表示电动机运行在超高档；电源线连接在绕组抽头H时，表示电动机运行在高档；电源线连接在绕组抽头M时，表示电动机运行在中档；电源线连接在绕组抽头L时，表示电动机运行在低档。The auxiliary winding group A is provided with a winding tap SH, a winding tap H, a winding tap M and a winding tap L, and the connection of the power line to different winding taps indicates that the motor operates in different gears. When the power line is connected to the winding tap SH, it means that the motor is running at super high level; when the power line is connected to the winding tap H, it means the motor is running at high level; When the winding tap is L, it means that the motor is running at low gear.
电容C的一端连接第一主绕组M1和第二主绕组M2的公共端，电容C的另一端连接在副绕组组A中任意副绕组的一端，其中，副绕组组A至少有一个副绕组作为启动绕组。One end of the capacitor C is connected to the common end of the first main winding M1 and the second main winding M2, and the other end of the capacitor C is connected to one end of any auxiliary winding in the auxiliary winding group A, wherein the auxiliary winding group A has at least one auxiliary winding as Start the winding.
需要说明的一点是，副绕组组A至少有一个副绕组作为启动绕组指的是副绕组组A至少有一个副绕组位于由第二主绕组M2、电容C和副绕组组成的三角形内，即电容C的另一端不与主绕组组M和副绕组组A的公共端连接。It should be noted that the secondary winding group A has at least one secondary winding as the starting winding, which means that the secondary winding group A has at least one secondary winding located in the triangle formed by the second main winding M2, the capacitor C and the secondary winding, that is, the capacitor The other end of C is not connected to the common end of the main winding group M and the secondary winding group A.
综上可以看出，本实用新型通过将电容C与主绕组组M的连接端移相到主绕组组M内部，相对于T型和L型两种接法，本实用新型主绕组组M被分为两个工作绕组，此时的容抗为Xc＝(1+a2)(X1m+Xf)，其中，Xc为容抗，a为副绕组与主绕组匝数的比值，X1m为等值电路中主相的电抗，Xf为副绕组的电抗。副绕组a不再是T型、L型的副/主绕组的关系，副绕组a变为原来的1/2，实际电容端电压Uc为电容端电压，Um为主相电压，Ua为副相电压，分解为其中，Ia为副相电流，xc为电容的容抗，a2为主副匝比，Im为主相电流.，R1m为主相电阻，R′f为副相电阻，x1m为主相电抗，x′f为副相电抗.，可以看出，a2实际为原来的1/4，即电容端电压有效减少(由原来第一主绕组M1匝数和第二主绕组M2的匝数总和，变为第二主绕组M2的匝数)，匝比a减少，Xc容抗减少，即电容端电压减少；同时，由于主绕组组M和副绕组组A的安匝比减少，使得副绕组组A中感应于调速绕组的电动势减少，因此，当单相电容运转电动机处于高档运行时，低档需要等同于T型绕组1/3的绕组就可以达到很低的低档转速，调速绕组少，感应电压明显降低。可以看出，本实用新型提供的接线结构有效减少了感应电压超标、电容端电压超标情况的发生，从而提高了单相电容运转电动机工作的可靠性。In summary, it can be seen that the utility model shifts the phase of the connection end of the capacitor C and the main winding group M to the inside of the main winding group M. Compared with the T-type and L-type connections, the utility model’s main winding group M is Divided into two working windings, the capacitive reactance at this time is Xc=(1+a2 )(X1m+Xf), where Xc is the capacitive reactance, a is the ratio of the number of turns of the secondary winding to the main winding, and X1m is the equivalent The reactance of the main phase in the circuit, Xf is the reactance of the auxiliary winding. The secondary winding a is no longer the relationship between T-type and L-shaped secondary/main windings, the secondary winding a becomes 1/2 of the original, and the actual capacitor terminal voltage Uc is the capacitor terminal voltage, Um is the main phase voltage, Ua is the secondary phase voltage, decomposed into Among them, Ia is the secondary phase current, xc is the capacitive reactance of the capacitor, a2 is the primary and secondary turn ratio, Im is the primary phase current, R1m is the primary phase resistance, R′f is the secondary phase resistance, x1m The primary phase reactance, x′f is the secondary phase reactance. It can be seen that a2 is actually 1/4 of the original, that is, the capacitor terminal voltage is effectively reduced (by the number of turns of the original first main winding M1 and the number of turns of the second main winding M2 The sum of the number of turns becomes the number of turns of the second main winding M2), the turns ratio a decreases, and the capacitive reactance of Xc decreases, that is, the capacitor terminal voltage decreases; at the same time, due to the decrease of the ampere-turns ratio of the main winding group M and the secondary winding group A , so that the electromotive force induced by the speed regulating winding in the auxiliary winding group A is reduced. Therefore, when the single-phase capacitor running motor is in high-grade operation, the low-speed gear needs a winding equal to 1/3 of the T-shaped winding to reach a very low low-speed speed. There are fewer speed regulating windings, and the induced voltage is significantly reduced. It can be seen that the wiring structure provided by the utility model effectively reduces the occurrence of excessive induced voltage and capacitor terminal voltage, thereby improving the reliability of the single-phase capacitor-operated motor.
需要说明的一点是，本实用新型公开的单相电容运转电动机的接线结构相对于现有技术中的T型和L型两种接法，可以命名为H型接法。It should be noted that, compared with the T-type and L-type connections in the prior art, the connection structure of the single-phase capacitor-operated motor disclosed in the utility model can be named as the H-type connection.
其中，本实施例中的电容C为电动机运行电容。Wherein, the capacitor C in this embodiment is the running capacitor of the motor.
需要说明的一点是，第一主绕组M1的匝数和第二主绕组M2的匝数可以相同也可以不同，此处不做限定。It should be noted that the number of turns of the first main winding M1 and the number of turns of the second main winding M2 may be the same or different, which is not limited here.
副绕组组A所有副绕组的匝数可以相同、可以不同或是不完全相同，此处不做限定。The number of turns of all the secondary windings of the secondary winding group A may be the same, different or not completely the same, which is not limited here.
为进一步优化上述实施例，单相电容运转电动机的接线结构还可以包括：电阻R；In order to further optimize the above embodiment, the wiring structure of the single-phase capacitor running motor may further include: a resistor R;
主绕组组M远离副绕组组A的一端通过电阻R与零线连接。One end of the main winding group M away from the secondary winding group A is connected to the neutral line through a resistor R.
需要说明的是，虽然单相电容运转电动机的调速范围比较广，但是受制本身为椭圆磁场，在多档位的调速中，低档位的磁场畸变严重，造成低档的转速不稳定、启动力矩差等现象。同时，由于转差率极大(例如，高档输出49W时，低档只有1.5W-2.0W的输出)，低档转矩小，出现低档不启动的情况。It should be noted that although the speed regulation range of the single-phase capacitor running motor is relatively wide, it is constrained by the elliptical magnetic field itself. In the multi-gear speed regulation, the magnetic field distortion of the low gear is serious, resulting in unstable speed at low gear and low starting torque. poor phenomenon. At the same time, due to the extremely large slip rate (for example, when the high-grade output is 49W, the low-gear output is only 1.5W-2.0W), the low-gear torque is small, and the low-gear does not start.
因此，本实用新型为减少低档不启动情况的发生，参见图4，本实用新型另一实施例公开的一种单相电容运转电动机的H型接线电路图，结合图3和图4，电容C的另一端连接副绕组组A中任意两个副绕组的公共端。Therefore, in order to reduce the occurrence of low-grade non-starting situations in the utility model, refer to Fig. 4, which is an H-type wiring circuit diagram of a single-phase capacitor running motor disclosed in another embodiment of the utility model. Combining Fig. 3 and Fig. 4, the capacitor C The other end is connected to the common end of any two secondary windings in secondary winding group A.
举例说明，在图4中，副绕组组A包括第一副绕组A1、第二副绕组A2、第三副绕组A3和第四副绕组A4，电容C的另一端连接第一副绕组A1和第二副绕组A2的公共端，当然也可以连接在第二副绕组A2和第三副绕组A3的公共端，或是第三副绕组A3和第四副绕组A4的公共端，此处不做限定。For example, in FIG. 4, the secondary winding group A includes the first secondary winding A1, the second secondary winding A2, the third secondary winding A3 and the fourth secondary winding A4, and the other end of the capacitor C is connected to the first secondary winding A1 and the fourth secondary winding A1. The common end of the second auxiliary winding A2, of course, can also be connected to the common end of the second auxiliary winding A2 and the third auxiliary winding A3, or the common end of the third auxiliary winding A3 and the fourth auxiliary winding A4, which is not limited here .
需要说明的一点是，图4实施例中只有四个档位，本实用新型公开的H型接法并不局限于三档、四档，通过增加副绕组组A中副绕组的数目，还可以延伸到五档、六档等。It should be noted that there are only four gears in the embodiment of Fig. 4, and the H-type connection method disclosed in the utility model is not limited to the third gear and the fourth gear. By increasing the number of auxiliary windings in the auxiliary winding group A, it can also be Extended to fifth gear, sixth gear, etc.
举例说明，单相电容运转电动机的H型接线具有五档的接线电路图参见图5，结合图4和图5可知，单相电容运转电动机具有五档时，只需增加一个副绕组，如图5中的第五绕组A5。For example, the H-type wiring of a single-phase capacitor-operated motor has five gears. Refer to Figure 5 for the wiring circuit diagram. Combining Figures 4 and 5, it can be seen that when a single-phase capacitor-operated motor has five gears, only one auxiliary winding needs to be added, as shown in Figure 5. The fifth winding A5 in.
综上可以看出，在图4公开的实施例中，第二副绕组A2、第三副绕组A3和第四副绕组A4不再具有副绕组的性质，即不再作为启动绕组，而是在降低转速时作为降压线圈，此时，只有第一副绕组A1作为启动绕组，因此，高档与低档间的转差率减小，低档转矩增大，从而有效减少了低档不启动情况的发生。In summary, it can be seen that in the embodiment disclosed in FIG. 4 , the second secondary winding A2, the third secondary winding A3 and the fourth secondary winding A4 no longer have the properties of secondary windings, that is, they are no longer used as start-up windings, but in When the speed is reduced, it is used as a step-down coil. At this time, only the first secondary winding A1 is used as the starting winding. Therefore, the slip rate between the high gear and the low gear is reduced, and the torque of the low gear is increased, thereby effectively reducing the occurrence of low gear non-start. .
此时，若第二副绕组A2、第三副绕组A3和第四副绕组A4匝数有变动，单相电容运转电动机的转速下降幅度很快，但是力矩变动很慢，相对于T型接法，当转速的变化量相同时，H型接法的转速低很多，但是转矩变动很少，支持了低档启动力矩保证，从而本实用新型解决了调速比与低压启动转矩的矛盾。At this time, if the number of turns of the second secondary winding A2, the third secondary winding A3 and the fourth secondary winding A4 changes, the speed of the single-phase capacitor running motor will drop rapidly, but the torque will change very slowly. Compared with the T-type connection method , when the variation of the speed is the same, the speed of the H-type connection is much lower, but the torque changes little, which supports the guarantee of the low-grade starting torque, so that the utility model solves the contradiction between the speed regulation ratio and the low-voltage starting torque.
而且，单相电容运转电动机采用H型接法后，低档抽头只需要原来T型接法的1/3匝数就可以达到同样的低档转速，从而解决了T型接法槽满率过高的问题。这样，单相电容运转电动机在同等性能和同等结构的基础上，采用H型接法的成本相对于T型接法的成本可以减少15％。Moreover, after the single-phase capacitor running motor adopts H-type connection, the low-grade tap only needs 1/3 turns of the original T-type connection to reach the same low-grade speed, thus solving the problem of too high full rate of the T-type connection. question. In this way, on the basis of the same performance and the same structure, the cost of the H-type connection method can be reduced by 15% compared with the cost of the T-type connection method.
单相电容运转电动机采用H型接法，转差率的改变可以把原来的单相电容运转电动机的调速范围扩展到0.06-0.5，从而增加了单相电容运转电动机的使用范围。The single-phase capacitor-operated motor adopts the H-type connection method, and the change of the slip rate can expand the speed regulation range of the original single-phase capacitor-operated motor to 0.06-0.5, thereby increasing the application range of the single-phase capacitor-operated motor.
由于单相电容运转电动机采用H型接法时，主绕组组M的电流和副绕组组A的电流在高低档的变化不大，从而实现电流平衡变化，相对于L型接法在电动机端盖密封后温升快而言，本实用新型可以对温升进行有效控制。When the single-phase capacitor running motor adopts the H-type connection method, the current of the main winding group M and the current of the auxiliary winding group A have little change in high and low gears, so as to realize the current balance change. Compared with the L-type connection method, the current of the motor end cover In terms of rapid temperature rise after sealing, the utility model can effectively control the temperature rise.
需要说明的一点是，流过主绕组组M的电流IM和流过副绕组组A的电流IA均流向主绕组组M和副绕组组A的公共端，具体参见图6公开的单相电容运转电动机的H型接线的电流流向图。It should be noted that the current I M flowing through the main winding groupM and the current I A flowing through the secondary winding group Aboth flow to the common terminal of the main winding group M and the secondary winding group A, specifically refer to the single-phase Current flow diagram for an H-connection of a capacitor run motor.
