发明内容Contents of the invention

本发明的目的在于克服现有技术的不足之处，而提供一种能防止被窃电的电能表防窃电装置。The purpose of the present invention is to overcome the disadvantages of the prior art, and provide an anti-stealing device for electric energy meters that can prevent electricity theft.

一种电能表防窃电装置，其特征在于：包括有磁敏开关、磁片、滑动绝缘极柱、起止柱、密码锁、复位弹簧及接线柱，磁片设置于磁敏开关两触点的附近，并可相对磁敏开关做远离或靠近的往复直线运动，磁片与滑动绝缘极柱相连，滑动绝缘极柱通地预紧力弹簧插于接线柱内并可相对接线柱做往复直线运动，所述的预紧力弹簧将与滑动绝缘极柱相连的磁片压在能让磁敏开关两接触点吸合的位置处，在滑动绝缘极柱的一侧设置有一凹槽，由密码锁控制的起止柱被压紧的设置于滑动绝缘极柱的凹槽侧并在预紧力弹簧处于释放状态时滑动绝缘极柱的运行方向上，所述的磁敏开关的两触点分别与接线柱导电片的两触点相连，所述的导电片中段为由绝缘材料构成形成两端导电中间不导电的结构。An electric energy meter anti-stealing device is characterized in that it includes a magnetic sensitive switch, a magnetic sheet, a sliding insulating pole, a start and stop column, a combination lock, a return spring and a terminal, and the magnetic sheet is arranged on the two contacts of the magnetic sensitive switch. Nearby, and can do reciprocating linear motion away from or close to the magnetic sensitive switch. The magnetic sheet is connected with the sliding insulating pole, and the sliding insulating pole is inserted into the terminal through the pre-tightening force spring and can perform reciprocating linear motion relative to the terminal. , the pre-tightening force spring presses the magnetic sheet connected to the sliding insulating pole at the position where the two contact points of the magnetic sensitive switch can be pulled together, and a groove is arranged on one side of the sliding insulating pole, and the combination lock The start-stop column of the control is pressed and arranged on the groove side of the sliding insulating pole, and in the running direction of the sliding insulating pole when the pre-tightening force spring is in the released state, the two contacts of the magnetic sensitive switch are respectively connected to the wiring The two contacts of the column conductive sheet are connected, and the middle section of the conductive sheet is made of insulating material to form a structure in which both ends are conductive and the middle is non-conductive.

这种结构的电能表防窃电装置，由于磁敏开关是一种特殊开关，它的两个触点由特殊材料制成，被封装在真空的玻璃管里。只要用磁铁接近它，两个触点就会吸合在一起，使电路导通。因此本发明利用磁敏开关的这一特点，将磁敏开关引入到防窃电装置中，并在磁敏开关附近设置磁片，利用磁片来控制磁敏开关的吸与合，而磁片又通过简单巧妙的结构，即将磁片与滑动绝缘极柱相连，将滑动绝缘极柱通过预紧弹簧压在接线柱中，一旦有人窃电将输入电源火线从电表接线柱拨出，这时滑动绝缘极柱由于预紧弹簧的作用立即动作，使绝缘极柱带动磁片远离磁敏开关，从而使磁敏开关的两触点分离，使得输入端火线被断开，从而达到切断输入火线的功能，在绝缘极柱动作的同时，起止柱在绝缘极柱的凹槽与其相吻合的那一刻滑入凹槽内，由于密码锁的作用，起止柱将滑动绝缘极柱锁死，使之无法复位，从而实现切断供电，以起到防窃电的目的。如需恢复供电，必须有供电部门人员将设置好的密码打开后，使得滑动绝缘极柱复位并将电源火线接入接线柱从而使滑动绝缘极将磁片顶起使其靠近磁敏开关，使接点动作闭合恢复正常工作。The electric energy meter anti-stealing device of this structure, because the magnetic sensitive switch is a kind of special switch, its two contacts are made of special materials, are encapsulated in the glass tube of vacuum.

The insulated pole moves immediately due to the action of the pre-tightened spring, so that the insulated pole drives the magnetic piece away from the magnetic sensitive switch, so that the two contacts of the magnetic sensitive switch are separated, and the live wire of the input terminal is disconnected, thereby achieving the function of cutting off the input live wire , while the insulating pole is moving, the start-stop column slides into the groove at the moment when the groove of the insulating pole matches with it. Due to the function of the code lock, the start-stop column locks the sliding insulating pole so that it cannot be reset , so as to cut off the power supply, so as to prevent electricity theft. If the power supply needs to be restored, the personnel of the power supply department must open the set password, reset the sliding insulating pole and connect the live wire of the power supply to the terminal, so that the sliding insulating pole can lift the magnetic piece and make it close to the magnetic switch, so that The contact action is closed to resume normal operation.

具体实施方式Detailed ways

下面结合实施例对本发明进行更详细的描述。The present invention will be described in more detail below in conjunction with examples.

实施例1 Example 1

一种如图1-6所示的电能表防窃电装置，包括一个16A干簧管1、一块钕铁硼磁片2、滑动绝缘极柱3、起止柱4、三位数字密码锁5、预紧弹簧6及接线柱7共同组成一个电能表防窃电装置。钕铁硼磁片设置于干簧管两触点的附近，并可相对干簧管做远离或靠近的往复直线运动，磁片与滑动绝缘极柱相连，滑动绝缘极柱通地预紧力弹簧插于接线柱内并可相对接线柱做往复直线运动，所述的预紧力弹簧将与滑动绝缘极柱相连的磁片压在能让干簧管两接触点吸合的位置处，在滑动绝缘极柱的一侧设置有一凹槽，由密码锁控制的起止柱被压紧的设置于滑动绝缘极柱的凹槽侧并在预紧力弹簧处于释放状态时滑动绝缘极柱的运行方向上，所述的干簧管的两触点分别与接线柱导电片9的两触点相连，所述的导电片中段为由绝缘材料—胶木绝缘体10构成形成两端导电中间不导电的结构。An electric energy meter anti-stealing device as shown in Figure 1-6, comprising a16A reed switch 1, a NdFeBmagnetic sheet 2, a slidinginsulating pole 3, a start andstop column 4, a three-digit combination lock 5, The pre-tensionspring 6 and theterminal post 7 jointly form an electric energy meter anti-stealing device. The NdFeB magnetic sheet is set near the two contacts of the reed switch, and can move away from or close to the reed switch in a reciprocating linear motion. The magnetic sheet is connected to the sliding insulating pole, and the sliding insulating pole is connected to the ground preload spring. It is inserted into the terminal and can perform reciprocating linear motion relative to the terminal. The pre-tightening force spring presses the magnetic piece connected to the sliding insulating pole at the position where the two contact points of the dry reed switch can be pulled together. There is a groove on one side of the insulating pole, and the start-stop column controlled by the combination lock is pressed tightly on the groove side of the sliding insulating pole and is in the running direction of the sliding insulating pole when the pre-tightening force spring is in the released state. , the two contacts of the reed switch are respectively connected to the two contacts of the conductive sheet 9 of the terminal, and the middle section of the conductive sheet is made of insulating material—bakelite insulator 10 to form a conductive structure at both ends and a non-conductive middle.

在正常的情况下，干簧管是一组闭合的接点，接点1、2静态闭合，正常供电，即导线8顶住滑动绝缘极柱3，使钕铁硼磁片2接近16A干簧管1，干簧管接点1、2闭合，接通输入电路，使电能表处于正常工作状态。一旦有人窃电将输入电源火线从电表接线柱拔出，这时防窃电滑动绝缘极柱3由于预紧弹簧6的作用立即动作，起止柱4滑向槽内，使钕铁硼磁片2离开16A干簧管1，此时干簧管的静合接点1、2被拉开，将输入端火线断开，从而达到切断输入火线的功能。这时由于三位数字密码锁5的作用，起止柱4将滑动绝缘极柱3锁死，使之无法复位，实现切断供电，这样起到防窃电的目的。如需恢复供电，只有供电部门人员用设置好的密码打开后，滑动绝缘极柱3才能复位，并重新接入导线8，复位后的滑动绝缘极柱3将钕铁硼磁片2顶起，靠近16A干簧管1，使干簧管1动作，接点1、2闭合，闭合后恢复正常工作。Under normal circumstances, the reed switch is a group of closed contacts, thecontacts 1 and 2 are statically closed, and the power supply is normal, that is, thewire 8 withstands the sliding insulatingpole 3, so that the NdFeBmagnetic sheet 2 is close to the16A reed switch 1 , the dryreed switch contacts 1 and 2 are closed, and the input circuit is connected, so that the electric energy meter is in a normal working state. Once someone steals the electricity and pulls out the live wire of the input power from the terminal of the ammeter, the anti-theft sliding insulatingpole 3 will act immediately due to the effect of thepre-tightening spring 6, and the start andstop column 4 will slide into the groove, so that theNdFeB magnet 2 Leaving the 16Adry reed switch 1, thestatic contact 1 and 2 of the dry reed switch are pulled apart at this time, and the live wire of the input terminal is disconnected, thereby achieving the function of cutting off the live wire of the input. At this time, due to the effect of the three-digit combination lock 5, the start and stoppost 4 locks the slidinginsulation pole post 3, so that it cannot be reset, and the power supply is cut off, so that the purpose of preventing electricity theft is played. If the power supply needs to be restored, the sliding insulatingpole 3 can be reset only after the personnel of the power supply department open it with the set password, and thewire 8 is reconnected, and the reset sliding insulatingpole 3 lifts the NdFeBmagnetic sheet 2, Close to the 16Adry reed switch 1 to make thedry reed switch 1 act, thecontacts 1 and 2 are closed, and the normal operation resumes after closing.

本实施例未述部分与现有技术相同。The parts not described in this embodiment are the same as the prior art.
