Description

Technical Field

The utility model is provided with an iron block, an electromagnet and a tension spring. During the use of the new energy inverter leakage test device, the grip rod can be held and the electromagnet is turned on. The electromagnet is energized to adsorb the iron block on one side, and the contact is in a retracted state. Then, the two sets of side plates are located outside the inverter. At this time, the side plate position is maintained, and the electromagnet is turned off. The tension spring gives the iron block a force, so that multiple sets of contacts are respectively against the concave and convex areas at various places on the outside of the inverter. Compared with the existing leakage test device, there is no need to move the conductive rod to perform multi-point leakage detection on the surface of the inverter, which effectively improves the efficiency of leakage and leakage detection.

[0004] The contact position is not adjustable. When detecting inverters of different sizes, it is easy for the contact to fail to fit the concave and convex areas at various locations, which affects the detection effect of the inverter.
