Abstract:
Quite a lot of medium voltage switchgear manufacturers lack understanding of power system operation mode deeply and knowledge reserves of insulation material characteristics，which leads to imperfectness of qualification schemes，and unreasonable selection of qualification test items.As a result，it is impossible to ensure that the equipment can correctly perform safety functions in abnormal or even normal operation condition，and a lot of qualification expenses are wasted.This paperdiscusses the type test and special performance test of qualification and puts forward an economical and operable qualification scheme.This study provides reference and guidance for the qualification of domestic 1E medium voltage switchgear manufacturers.
