1．Device Overview

Simulated Circuit Breaker Device IIIMainly used for whole set testing of relay protection devices，And replacing real circuit breakers in other experimental projects,As a substitute equipment for the actual circuit breaker during the transmission test of the relay protection and automatic device with switch assembly system；Accurate, reliable, and unlimited number of actions can greatly improve the correctness and completeness of the test, minimize the actual number of actions of the circuit breaker, and improve its service life.Simulated Circuit Breaker Device IIIcan be paired withUsed in conjunction with relay protection verification device，It can also be used independentlyEspecially in the case of newly built factories or stations where the high-voltage circuit breakers are not properly adjusted or the DC power supply is not connected, using this device for relay protection testing will not be affected by external factors, thereby shortening the debugging time and improving the efficiency of the testing work. The use of this device in manufacturers and research departments is more efficient and effective. Other similar applications can be handled on a case by case basis.
