Electrical Chassis Car

main application and function

The Electrical Chassis Car is mainly used to install the circuit breaker, transformer and other components in the extraction switching equipment, and to advance and exit them as the auxiliary operation of the connection of the components and the bus.

When the chassis car works with the internal mechanism of the circuit breaker and other interlock mechanism of the middle cabinet, it can meet the requirements of "five defense" interlock in GB3906. The specific functions are as follows: 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 will be unable to move, so as to prevent the occurrence of the wrong isolation contact with load.

2. When the hand car is about 10mm in the working position or away from the test / isolation position, the ground switch cannot be closed to prevent the misclosing of the ground switch.

3. When the ground switch is closed, the mobile vehicle shall not move from the test / isolation position to the working position to prevent the ground switch from closing the circuit breaker in the closing position.

4. After the chassis car enters the cabinet, once leaving the test / isolation position, the hand car cannot be drawn out from the cabinet.

• chassis car ordering instructions

1. Indicate the chassis car model, lock plate code, auxiliary switch specifications, grounding mode, etc.

2. The specification of auxiliary switch refers to the specifications of the auxiliary switch itself (that is, the specifications in front of the chassis).Generally for 5 groups, 6 groups of contacts, can also provide 10 sets of contacts (composed of 2 auxiliary switches in series)

3. 24kV chassis car only travel from 200mm to 300mm, the rest unchanged, add / X300 after the prototype number.

4. If there are special requirements, please negotiate with our factory to solve the problem.
