Background technique

The air circuit breaker is an air circuit breaker (also known as an automatic switch), which is a kind of circuit breaker. As long as the current in the circuit exceeds the rated current, it will automatically disconnect the switch; the air circuit breaker is widely used in AC and DC devices below 500V. In the circuit, it is used to connect, break and carry the rated working current and short circuit, overload and other fault currents; when overload, short circuit, voltage drop or disappears in the circuit, it can automatically cut off the circuit for reliable protection. In order to ensure the safe and reliable operation of the power grid, during the switching operation, the power circuit breaker needs to be switched accordingly; while the conventional substation circuit breaker must be in the disconnected state (that is, the panel button shows "OFF" state), only in the switching operation. During the gate operation, the corresponding switching is carried out; through the statistical analysis of the time of each link of the actual switching operation, it is found that the switching operation takes a lot of time, which affects the efficiency of the switching operation. The reason is that the operation and maintenance personnel are performing the switching operation task Among them, the operation of the 500kV circuit breaker must be performed in strict accordance with the regulations after the motor power circuit breaker is operated in the terminal box of the switchyard, and then the remote pulling operation is performed on it, and the 500 kV substation occupies a large area, and it is necessary to go back and forth during switching. More time-consuming, resulting in more time-consuming switching operation.

Therefore, there is a need for an air breaker assembly that can be switched remotely, which can realize remote switching operations on the air breaker, thereby shortening the operating time of the air breaker for the equipment power supply, improving the switching operation efficiency, and reducing the labor intensity of the staff.
