摘 要：
The fire-fighting special purpose circuit-breaker is a special low-volt circuit-breaker, which is used for remote control in fire-fighting engineering.This paper introduces composition, principle of work and application about fire-fighting special purpose circuit-breaker.At the same time,the author identifies the defects of the current fire-fighting special purpose circuit-breaker in engineering by engineer testing,and by analyzing the factors of its low-reliability due to unstable mechanical trip force and heavy voltage loss.Finally,a solution based on experimentation was prop- osed,which modifies product process structure and adapts mini-power coil,and increases reliability of fire-fighting special purpose circuit-breaker.
