1.After the integral DCS modification of No. 1 generator set in Zhujiang power plant, the control tactics of tripcircuit for pulverizing system, test and the improvement of related circuit were introduced.
2.Power system relay protection can detect that faults or abnormal operating conditions occurring in the electric equipments and trip the circuit breakers or send signals.
4.Shunt Trip Shunt trip is a feature added to a circuit breaker or fusible switch to permit the remote opening of the breaker or switch by an electrical signal.
5.The electromagnetic system design of instantaneous trip used to be calculated on the basis of experience and magnetic circuit and made low precision.
6.Air Circuit Breaker An air circuit breaker automatically interrupts the current flowing through it when the current exceeds the trip rating of the breaker.
7.The double isotope release unit applying piston-like igniter and efficient control electric circuit can release "the tiny ball" and isotope at one pass trip, and enhances testing efficiency.
8.The structure design of spring actuator for 110kV selfenergy type SF_6 circuit breaker is introduced. The structure design of the trip for open operation and the relationship between the energy storage and the work of open/close operation are high-lighted.
