Project Description: ZHAOWEI micro drive system can be applied to automatic reclosing (small circuit breaker). It adopts multi-stage helical worm gear to optimize the service life and performance of automatic reclosing, and realize intelligent opening and closing of circuit breakers. An intelligent reclosing device (circuit breaker) can be installed as an effective anti-accident measure on overhead power lines (cannot be applied to general cable power lines). That’s to say when the line fails, the relay protection causes the circuit breaker to trip. The automatic reclosing device recloses the circuit after a short time interval, thereby improving the reliability of the power supply of the power system. In most cases, line faults (caused by lightning strikes, wind damage, etc.) are temporary. After the circuit breaker trips, the insulation performance (insulators and air gaps) of the line can be restored, and the recloser can reclose the circuit.
Advantages
- Enhancing the effectiveness of transmission lines.
- Improving the stability of system operation.
- Avoid mistaken tripping of the circuit breaker.
- Speed up voltage recovery of the power system after accident treatment.
