Chassis uses and functions:

1, only when the hand car is in the test/isolation or working position, the circuit breaker can be closed, and after the circuit breaker is closed, the hand car can not move, thereby preventing the occurrence of mis-connection and mis-closing isolation contacts with load.
2, the hand car in the working position or away from the test/isolation position of about 10mm, the grounding switch can not be closed, to prevent live mis-closing of the grounding switch.
3, when the grounding switch is closed, the hand car can not move from the test/isolation position to the working position to prevent the grounding switch from closing the circuit breaker when the grounding switch is in the closing position.
4. After the chassis car enters the cabinet, once it leaves the test/isolation position, the hand car cannot be extracted from the cabinet.
