Background
In the process of transformer maintenance, the SF6 gas pressure of the 220kV or 110kV circuit breaker is often found to be low, and the circuit breaker needs to be supplemented with gas. In the air supply process, because the air charging interface of the circuit breaker SF6 is in plane contact, when air charging is carried out, an air charging connector on the side of the air charging pipe and an air charging opening of the circuit breaker need to be pressed by an adjustable wrench or connected by a bolt, so that the air path is ensured to be smooth. However, in the actual working process, the method has two problems:
1. when the adjustable wrench is pressed and connected, the pressing force needs to be kept all the time, otherwise, air is possibly mixed, and when the adjustable wrench is used for supplementing air for a long time, the phenomenon that an overhaul worker often falls off when holding the adjustable wrench due to physical problems;
2. after the gas is filled, the pressure of about 0.6Mpa exists in the gas chamber, so that when the gas-filled connector is pulled out, the connector is pressed out, and the risk of damaging maintainers exists.
The air supply process is time-consuming and labor-consuming when the air supply interface is connected with the circuit breaker, and the risk is high in the operation process, and the air supply work is large in daily work in consideration of the fact that equipment with the type of interface occupies a large proportion in a transformer substation, so that the air supply process is very necessary to be simplified and the operation risk is reduced.
