The difference between spring positioning pins and positioning pins

Spring energy storage mechanisms are currently commonly used mechanisms, and their closing and opening rely on springs to provide energy. The tripping and closing coil only provides energy to pull out the positioning pin of the spring, so the tripping and closing current is generally not high. Spring energy storage is achieved by compressing the spring with an energy storage motor

For the spring operating mechanism, the closing buar mainly supplies power to the energy storage motor, and the current is not too large, so the difference between the closing buar and the control buar is not too significant. There is generally nothing special to pay attention to when protecting and cooperating with it

Spring positioning pin structure principle

(1) There are two springs inside the circuit breaker, namely the closing spring and the tripping spring.

. The closing spring relies on electric traction for energy storage (compression), while the tripping spring relies on the potential energy storage when the closing spring releases (tension)

After the circuit breaker is closed, the closing spring limit switch automatically starts the motor circuit for energy storage. The motor rotates and compresses the closing spring to a certain degree before stopping operation. The closing spring is locked by the positioning pin

(3) Before the next release of the closing spring, the motor will no longer run. After troubleshooting the motor, stopping the motor to a certain extent indicates that the energy storage of the closing spring is complete
