Circuit breaker simulation screen

Circuit breaker simulation screenSimulated circuit breaker screen is a combination of multiple independent simulated circuit breakers into a standard cabinet to form a simulated screen, which can be used for teaching and testing in educational institutions and research institutes.

This simulated circuit breaker is a new product developed by our company using the 51 microcontroller based on the original simulated circuit breaker. Due to the use of a new type of microcontroller and program control, the accuracy of the entire machine has been improved, making it a commonly used equipment for testing relay protection devices. This product has the characteristics of innovative design ideas, reliability and durability, convenient wiring, small size, and light weight. It is a commonly used equipment for testing relay protection devices. This product has the characteristics of innovative design ideas, reliability and durability, convenient wiring, small size, and light weight. It can be used in conjunction with various microcomputer based relay protection testing devices to complete the experimental and testing work of complete sets of relay protection devices for various voltage levels in the power system relay protection department, ensuring the integrity of the complete set of relay protection devices and improving the calibration quality of the devices.
