Portable Microcomputer-based High Voltage Circuit Breaker Simulation Device Model: SB6250
1. Main Hardware Configuration
Six independent trip and close coils; 12 pairs of circuit breaker position output contacts;
One auxiliary DC power output (switchable between 110V/220V)
2. Main Functional Features
The SB6250 microcomputer-based high voltage circuit breaker simulation device is mainly used for complete group testing of relay protection devices and to replace actual high voltage circuit breakers in projects such as standby power supply automatic switching device tests. During complete group testing, it simulates the tripping and closing of high voltage circuit breakers to avoid adverse effects caused by repeated complete group tests leading to repeated opening and closing of high voltage circuit breakers. This simulation device is a supporting product for the microcomputer relay protection testing system and can also be used in conjunction with relay protection calibration devices from other manufacturers. Especially in cases where the high voltage circuit breaker in new plants or substations has not been properly adjusted or the DC power supply has not been energized, using this device for relay protection tests will not be affected by external factors, thereby shortening debugging time and improving testing work efficiency. Additionally, the instrument can be optionally equipped with remote control function. The host computer software monitors the circuit breaker's opening and closing status through serial port (USB), Ethernet port, WiFi, and other connection methods. It can also connect multiple devices via the network to form a scenario-based simulated circuit breaker panel, making the system more effective with less effort in relay protection manufacturers and scientific research departments.
