Before and after the EMC immunity test, it is necessary to verify whether the main performance indicators of the tested equipment are reduced. The protection and action characteristics test device is the equipment to verify the main performance indicators of mining electrical switches and motors. Its research and development involves a variety of equipment to cooperate to realize its system functions. However, there is no single manufacturer in the market to produce such equipment or system, which needs independent research and development according to the needs of the electrical equipment tested in the laboratory. The protection and action characteristic test device is applied to the mechanical characteristic test of high-voltage switch. It can be used as the test equipment for high-voltage and low-voltage leakage action value and time test, as well as the leakage current and capacitive current compensation efficiency test. It can also be used for the characteristic test of the test device, overcurrent protection characteristic test and other test items.
