s4, sequentially connecting wires with all detection assemblies to diagnose and check the electric elements in the cabinet body in a mode in the step S3;
And S5, directly maintaining or replacing the damaged electric element according to the checking result.
6. The high-voltage switchgear capable of diagnosing system failure according to claim 5, wherein in step S1, when one of the detecting components is connected to the multimeter via a wire, the conductive pin at one end of the wire is inserted into the conductive contact,
The same hand pad is needed between the fixed plate and the door plate, so that the detection probe cannot be in false contact with the wiring pin when the conductive pin is inserted.
