背景技术Background technique
电能表，是专用来计量一段时间内电能累积值的仪表，也称电度表、表计。电能表的工作原理为，当把电能表接入被测电路时，电流线圈和电压线圈中就会流过交变电流，交变电流在铁芯中产生交变的磁通，交变磁通穿过铝盘时，在铝盘中感应出涡流，涡流在磁场中受到力的作用，从而使铝盘获得转矩而转动，进而带动计数器将所消耗的电能指示出来。若电能表出现故障如烧毁，计量的电能示数则不能正常显示出来。An electric energy meter is an instrument dedicated to measuring the cumulative value of electric energy over a period of time, also known as an electric watt-hour meter or a meter. The working principle of the electric energy meter is that when the electric energy meter is connected to the circuit under test, the alternating current will flow through the current coil and the voltage coil, and the alternating current will generate alternating magnetic flux in the iron core, and the alternating magnetic flux will When passing through the aluminum disk, an eddy current is induced in the aluminum disk, and the eddy current is subjected to force in the magnetic field, so that the aluminum disk obtains torque and rotates, and then drives the counter to indicate the consumed electric energy. If the watt-hour meter breaks down, such as burning out, the metered electric energy indication cannot be displayed normally.

However, in the method described above, the operator needs to touch the connection clip, and the metal body of the connection clip is not sufficiently insulated, which is prone to electric shock accidents and has low safety.
