The high-voltage circuit breaker simulation device is mainly used for the whole set of relay protection devices and to replace the real high-voltage circuit breakers in the standby power supply self-injection device test (the five sets of circuit breakers can be flexibly simulated as needed). In the whole set of tests, the jump and closing of the high-voltage circuit breaker are simulated to avoid the adverse effects caused by the repeated splitting of the high-voltage circuit breaker due to the repeated whole set of tests. The simulation device is an accessory product of the microcomputer relay protection test system, especially In the case that the high-voltage circuit breakers of new power plants and substations are not adjusted or DC power is not supplied, the relay protection test using this device will not be affected by external factors, thus shortening the commissioning time and improving the test work efficiency. Manufacturers and research institutes and other departments will use the device to get twice the result with half the effort. Other similar applications can be handled on a case-by-case basis.
Analog device principle
The simulation device adopts a single-chip microcomputer as the control core, realizes the functions of analog high-voltage circuit breaker jumping and closing time setting, input signal logic control, etc., thereby simulating the jumping and closing action of the high-voltage circuit breaker, and providing a completely isolated DC. Voltage output, the device is simple and reliable.
