Q&A:

? What voltage withstand tests are required for the switchgear? ?

If the switch cabinet needs to be withstand voltage overall, it is necessary to find out what the equipment in the cabinet is, and then use the low voltage withstand standard of the components in the cabinet as the overall withstand voltage test standard;

If the main body of the switchgear is the cabinet shell and the insulator, just hit 42kV according to the standard of the insulator;

If there is a dry-type transformer inside the switchgear, the lead wire is not removed during the test, and the hardware withstand voltage is applied together. It needs to be applied to 28kV when leaving the factory and 24kV for handover;

Before the AC withstand voltage test, some things must be removed from the lead, such as the lightning arrester in the cabinet, the overvoltage absorption device, the load of the voltage transformer, the live indicator, etc.

?What is the main purpose of the high and low voltage switchgear energization test bench?

The high and low voltage switchgear energization test bench is used for the high and low voltage switchgear manufacturers to conduct various energization tests on the high and low voltage switchgear produced before leaving the factory. It can provide various AC and DC power supplies to facilitate the detection of switch cabinets and improve work efficiency.
