Analog Circuit Breaker Unit

The MOEORW-WKM36 simulated circuit breaker device is a real circuit breaker replacement device specifically for relay protection testing, positioned as a core supporting device for industrial-grade testing.

It boasts core advantages such as manual operation, adjustable multiple parameters, and intelligent control, offering stable performance and adaptability to various testing needs.

It is applicable to various testing scenarios, including relay protection system testing, power plant construction and commissioning, and power production research.

The MOEORW-WKM36 simulated circuit breaker device is mainly used for the overall testing of relay protection devices , and as a substitute for real circuit breakers in other test projects. It serves as a replacement for the actual circuit breaker during the transmission testing of relay protection and automatic devices with switches, offering accurate and reliable operation with unlimited operation times. This significantly improves the correctness and completeness of the test, minimizes the number of actual circuit breaker operations, and extends service life . This simulation device can be used in conjunction with relay protection calibration devices or independently . Especially in newly built plants and substations where high-voltage circuit breakers are not properly adjusted or have not been connected to DC power, using this device for relay protection testing will not be affected by external factors, thus shortening the commissioning time and improving testing efficiency. Its use in manufacturing plants and research institutions is particularly effective. Other similar applications can be handled according to specific circumstances. ( This device is mainly for simulating the opening and closing of permanent magnet circuit breakers .)

• Six sets of switch contacts, corresponding to the opening and closing coils ;
• Two sets of switching and sluice coils are also provided ;
