Description

Energy meter withstand voltage test device

technical field

The utility model relates to the field of high voltage resistance testing of electric energy meters.

Background technique

Before the watt-hour meter leaves the factory, it is necessary to carry out a high-voltage test on the watt-hour meter. First, apply a high voltage to the single-phase watt-hour meter for a period of time, and then check whether the single-phase watt-hour meter is intact. Since the traditional wiring method is difficult to withstand high voltage, we must use probes for detection. At present, the withstand voltage test of the electric energy meter only stays in manual installation of probes for testing. This method is very low in safety, and the operator needs to be vigilant all the time, and it is even more unfavorable for convenient and quick detection and work in other aspects.
