Relevant steps for debugging in nine aspects of KYN28 high -voltage cabinet
2022-11-30
High -voltage metal closed switch device consists of two parts: box and hand cart. The cabinet is separated from four independent compartments from the metal partition: the bus room, switching room, cable room, relay instrument room. Hand -to -vehicle can be divided into circuit breakers, quantity, and hand -to -hand cars according to the purpose. Band cars with different parameters can be freely swapped. The hand car has a test location and working location in the cabinet. Each position has a reliable connection device. High -voltage switch cabinets are chain, safe and reliable, and meet the "five defense" requirements:
1. Prevent errors from using circuit breakers;
2. Prevent the isolation pull switch with load, that is, to prevent the load from pushing the pull -pull car;
3. To prevent connecting the power cord, that is, to prevent the charging of the ground switch;
4. To prevent the ground wire from sending electricity, that is, to prevent the ground switch from sending electricity when the ground switch is located;
5. Prevent errors from entering the charged interval.
When the hand car of the circuit breaker is tested or working position, the circuit breaker can run together. After the circuit breaker is closed, the hand car cannot be moved to prevent the load from being pulled out and pushing away from the router.Only when the ground switch is at the position of the gate, the circuit breaker vehicle can move from the test location to the working location, and the ground switch can be closed only when the circuit breaker is in the test position, so as When you are closed, prevent ground switch from closed. When the ground switch is at the positioning position, the lower and rear doors cannot be opened to avoid errors in the band.
The plug was locked and could not be pulled out when I was working. In order to ensure the security and reliability of each chain device, it is not damaged, and it is necessary to operate in accordance with the lock -locking error operation program. When the hand car of the circuit breaker is tested or working position, the circuit breaker can run together. After the circuit breaker is closed, the hand car cannot be moved to prevent the load from being pulled out and pushing away from the router.
