技术领域technical field
本实用新型涉及控制电器保温技术领域，具体涉及一种控制电器及其加热装置。The utility model relates to the technical field of heat preservation of control electric appliances, in particular to a control electric appliance and a heating device thereof.
背景技术Background technique
很多控制电器例如断路器、熔断器、开关设备或者内置各类控制电器的仪表箱、电气控制箱等，都设置于高寒地区户外，当工作环境温度较低时控制电器的绝缘性能和开断能力都会受低温影响而急剧下降，甚至出现不能正常动作的现象。Many control appliances, such as circuit breakers, fuses, switchgear, or instrument boxes with built-in various control appliances, electrical control boxes, etc., are installed outdoors in alpine areas. When the working environment temperature is low, the insulation performance and breaking capacity of the control appliances All will be affected by the low temperature and will drop sharply, and even appear to be unable to operate normally.
为此，中国专利文献CN204957357公开了一种具有自动调温的仪表箱，该仪表箱内除安装有各类电子元器件外，还设有风扇、加热器以及温度控制器，所述元器件通过传感器电缆线与所述箱体外部的传感器连接，该仪表箱可通过温度控制器驱动风扇和加热器工作，使仪表箱在不同环境温度下单独开启风扇降温，或者单独开启加热器升温，使仪表箱可在恶劣气候下调节自身温度，为仪表箱内各元器件提供合适的工作温度。但该现有技术仍存在以下问题：1.当气温略低于设定温度或远低于设定温度时，加热器都会启动加热，前者环境温度略低、控制电器只需稍微加温，此时加热器功率过大，会造成不必要的能源损耗，后者环境温度极低、控制电器需要大幅升温，此时加热器功率过小，将无法维持元器件正常工作，加热器的供热能力不能随环境温度调节，而造成了能源浪费或保温能力不足；2.由于加热器安装于控制电器或电控箱内的固定位置处，会造成局部过热的情况，存在安全隐患。For this reason, Chinese patent document CN204957357 discloses a kind of instrument box with automatic temperature regulation, in addition to installing various electronic components and parts in this instrument box, also be provided with fan, heater and temperature controller, described components and parts pass through The sensor cable is connected to the sensor outside the box, and the meter box can drive the fan and heater to work through the temperature controller, so that the fan can be turned on separately to cool down the meter box at different ambient temperatures, or the heater can be turned on separately to heat up the meter box. The box can adjust its own temperature in bad weather, and provide a suitable working temperature for each component in the instrument box. But this prior art still has the following problems: 1. When the air temperature is slightly lower than the set temperature or far below the set temperature, the heater will start heating. When the power of the heater is too large, it will cause unnecessary energy loss. The ambient temperature of the latter is extremely low, and the temperature of the control electrical appliances needs to be greatly increased. At this time, the power of the heater is too small, and the normal operation of the components will not be maintained. It cannot be adjusted with the ambient temperature, resulting in energy waste or insufficient heat preservation capacity; 2. Since the heater is installed at a fixed position in the control appliance or the electric control box, it will cause local overheating and pose a safety hazard.

实施例一Embodiment one
图1为本实用新型的实施例一中提供的加热装置的俯视图；图2为图1所示的加热装置的电路图。如图1所示，本实施例提供的一种加热装置，包括：壳体1以及至少两个加热单元，每个所述加热单元包括电气连接的加热器和温度控制器，所述温度控制器设置有预设温度，所述温度控制器在环境温度低于或高于所述预设温度时，控制对应的所述加热器开启或停止加热，所述加热器设于所述壳体1内，每个所述温度控制器的所述预设温度不同。Fig. 1 is a top view of the heating device provided in Embodiment 1 of the present utility model; Fig. 2 is a circuit diagram of the heating device shown in Fig. 1 . As shown in Figure 1, a heating device provided by this embodiment includes: a housing 1 and at least two heating units, each of which includes an electrically connected heater and a temperature controller, and the temperature controller A preset temperature is set, and the temperature controller controls the corresponding heater to start or stop heating when the ambient temperature is lower or higher than the preset temperature, and the heater is arranged in the housing 1 , the preset temperature of each of the temperature controllers is different.
当环境温度低于或高于预设温度时，温度控制器即可控制对应的加热器开启或停止加热，这种设置使得当环境温度低于较高的预设温度时，加热装置可只启动较高预设温度所对应的加热单元内的加热器对控制电器进行加热升温，当环境温度继续降低至较低的预设温度时，加热装置可继续启动较低预设温度所对应的加热单元内的加热器，增加加热装置对控制电器的供热量，这种加热器的逐级启动有效避免了无论环境温度是略低于还是远低于预设温度，加热装置的加热器都会同时启动而造成能源浪费或保温能力不足的问题，使加热装置可以更好地根据实际环境温度逐级启动多个加热器，既可节约能源、利于环保，又能在极端低温下为控制电器提供足够的热量，维持控制电器的正常运行。When the ambient temperature is lower or higher than the preset temperature, the temperature controller can control the corresponding heater to start or stop heating. This setting makes the heating device only start when the ambient temperature is lower than the higher preset temperature. The heater in the heating unit corresponding to the higher preset temperature heats up the control electrical appliances. When the ambient temperature continues to drop to the lower preset temperature, the heating device can continue to activate the heating unit corresponding to the lower preset temperature The heater inside increases the heat supply of the heating device to the control appliance. The step-by-step activation of the heater effectively prevents the heaters of the heating device from starting at the same time no matter whether the ambient temperature is slightly lower or far lower than the preset temperature. However, the problem of energy waste or insufficient heat preservation capacity enables the heating device to start multiple heaters step by step according to the actual ambient temperature. Heat, maintain the normal operation of the control electrical appliances.
进一步地，每一所述温度控制器的预设温度包括预设启动温度值和预设断开温度值，所述预设断开温度值高于所述预设启动温度值，本实施例中提供的加热装置包括第一加热单元和第二加热单元，所述第一加热单元包括电气连接的第一加热器3和第一温度控制器8，所述第二加热单元包括电气连接的第二加热器5和第二温度控制器9，所述第二加热器5的额定功率高于所述第一加热器3的额定功率，所述第一温度控制器8设置有第一预设启动温度值和第一预设断开温度值，所述第二温度控制器9设置有第二预设启动温度值和第二预设断开温度值，第一预设断开温度值＞第一预设启动温度值＞第二预设断开温度值＞第二预设启动温度值，当环境温度低于第一预设启动温度值，第一加热器3启动加热，若此时控制电器由于受热致使温度小幅升高、超过第一预设启动温度值也不会立即停止第一加热器3加热，避免控制电器所处温度在短时间内再次降至第一预设启动温度值而第一加热器3再次启动，而是当控制电器所处温度升高至第一预设断开温度，第一加热器3才停止加热，此时的环境温度超过第一预设启动温度值较多，一段时间内不需启动加热器，有效减少温度控制器和加热器的频繁通断，有利于增加加热装置的使用寿命，降低维护成本；若此时环境温度继续降低至第二预设启动温度值，第一加热器3所提供的热量不足以维持控制电器的正常运行，则第二加热器5启动加热，此时第一加热器3与第二加热器5同时为控制电器进行加热，同样地，若此时控制电器所处温度开始回升，直至超过第二预设断开温度值，第二加热器5停止加热，由于第一预设启动温度值＞第二预设断开温度值，使得控制电器所处温度在升至第一预设启动温度值前即停止第二加热器5加热，避免了温度在第一预设启动温度值附近时，第二加热器5与第一加热器3同时启动加热所造成的不必要的能源浪费，甚至造成控制电器内部温度过高，不利于控制电器正常运行。Further, the preset temperature of each temperature controller includes a preset start-up temperature value and a preset cut-off temperature value, and the preset cut-off temperature value is higher than the preset start-up temperature value. In this embodiment The heating device provided comprises a first heating unit and a second heating unit, the first heating unit comprises an electrically connected first heater 3 and a first temperature controller 8, and the second heating unit comprises an electrically connected second heater 5 and a second temperature controller 9, the rated power of the second heater 5 is higher than the rated power of the first heater 3, and the first temperature controller 8 is provided with a first preset starting temperature value and the first preset cut-off temperature value, the second temperature controller 9 is set with a second preset start-up temperature value and a second preset cut-off temperature value, the first preset cut-off temperature value>the first preset Set the start-up temperature value>the second preset cut-off temperature value>the second preset start-up temperature value, when the ambient temperature is lower than the first preset start-up temperature value, the first heater 3 will start heating, Even if the temperature rises slightly and exceeds the first preset starting temperature value, the heating of the first heater 3 will not be stopped immediately, so as to prevent the temperature of the control appliance from dropping to the first preset starting temperature value again in a short time and the first heating The heater 3 starts again, but when the temperature of the control appliance rises to the first preset cut-off temperature, the first heater 3 stops heating. There is no need to start the heater within a certain period of time, effectively reducing the frequent on-off of the temperature controller and the heater, which is beneficial to increase the service life of the heating device and reduce maintenance costs; if the ambient temperature continues to drop to the second preset start-up temperature value at this time, The heat provided by the first heater 3 is not enough to maintain the normal operation of the control appliance, then the second heater 5 starts heating, and now the first heater 3 and the second heater 5 are heating for the control appliance simultaneously, similarly, If at this time the temperature of the control appliance starts to rise until it exceeds the second preset cut-off temperature value, the second heater 5 stops heating. Since the first preset start-up temperature value>the second preset cut-off temperature value, the control Before the temperature of the electrical appliance rises to the first preset starting temperature value, the second heater 5 is stopped to heat, so as to avoid that when the temperature is near the first preset starting temperature value, the second heater 5 and the first heater 3 are simultaneously The unnecessary waste of energy caused by starting the heating may even cause the internal temperature of the control appliance to be too high, which is not conducive to the normal operation of the control appliance.
优选地，每一所述温度控制器的所述预设断开温度值与所述预设启动温度值的温度差的范围为5-10℃。Preferably, the range of the temperature difference between the preset cut-off temperature value and the preset start-up temperature value of each of the temperature controllers is 5-10°C.
例如，本实施例中的第一温度控制器8的预设启动温度值为零下5℃，断开温度为5℃，第一加热器3的额定功率为150W；第二温度控制器9的预设启动温度值为零下20℃，断开温度为零下15℃，第二加热器5的额定功率为500W。For example, the preset start-up temperature of the first temperature controller 8 in this embodiment is minus 5°C, the cut-off temperature is 5°C, and the rated power of the first heater 3 is 150W; the preset temperature of the second temperature controller 9 It is assumed that the start-up temperature is minus 20°C, the cut-off temperature is minus 15°C, and the rated power of the second heater 5 is 500W.
需要说明的是，每一所述温度控制器的预设温度包括预设启动温度值和预设断开温度值，在其他实施例中，所述预设启动温度值与所述预设断开温度值还可以相等，即每个所述温度控制器设置有一个预设温度值，例如，所述第一温度控制器的预设温度值高于所述第二温度控制器的预设温度值，所述第二加热器的额定功率高于所述第一加热器的额定功率，当环境温度低于所述第一温度控制器的预设温度值时，第一加热器启动，由于此时环境温度略低于控制电器的正常工作温度，只需小功率的第一加热器启动加热即可满足控制电器的恒温运转；当环境温度继续降低至所述第二温度控制器的预设温度值时，第二加热器启动，此时环境温度较低，需要小功率的第一加热器与大功率的第二加热器同时启动加热，为控制电器提供热量维持运转；相反地，当环境温度高于第二温度控制器的预设温度值时，第二加热器关闭，此时仅由第一加热器为控制电器提供热量，当温度继续升高至第一温度控制器的预设温度时，第一加热器关闭，此时环境温度可满足控制电器的正常运转，这种设置的温度控制器结构简单，指令单一，不易出错，并且可及时为控制电器加热或停止加热，能源损耗低。It should be noted that the preset temperature of each temperature controller includes a preset start-up temperature value and a preset disconnection temperature value. In other embodiments, the preset start-up temperature value is disconnected from the preset The temperature values can also be equal, that is, each of the temperature controllers is provided with a preset temperature value, for example, the preset temperature value of the first temperature controller is higher than the preset temperature value of the second temperature controller , the rated power of the second heater is higher than the rated power of the first heater, when the ambient temperature is lower than the preset temperature value of the first temperature controller, the first heater starts, because at this time The ambient temperature is slightly lower than the normal operating temperature of the control appliance, and the constant temperature operation of the control appliance only needs to be activated by the first heater with a small power; when the ambient temperature continues to drop to the preset temperature value of the second temperature controller When the temperature is high, the second heater starts, and the ambient temperature is low at this time, so the low-power first heater and the high-power second heater are required to start heating at the same time to provide heat for the control appliances to maintain operation; on the contrary, when the ambient temperature is high At the preset temperature value of the second temperature controller, the second heater is turned off. At this time, only the first heater provides heat for the control appliance. When the temperature continues to rise to the preset temperature of the first temperature controller, The first heater is turned off. At this time, the ambient temperature can meet the normal operation of the control appliance.
