Description

technical field [0001] The invention belongs to the field of electricity, more specifically, it is a circuit breaker detector. Background technique [0002] In order to ensure the reliability of the circuit breakers used in the switchgear, testing and testing equipment is required to detect, verify and debug the circuit breakers used. Ensure that the circuit breakers used in the switchgear are fault-free. Since the existing circuit breaker can only be tested on the complete machine, it takes time and effort to test, validate and debug. [0003] The object of the present invention is to provide a circuit breaker detector. Contents of the invention [0004] Aiming at the above technical problems, the present invention provides a single-phase power supply, small size, safe and reliable circuit breaker detector. The invention includes: CD air switch (1), ZB1 closing coil voltage regulator (2), ZB2 undervoltage coil voltage regulator (3), ZB3 shunt coil voltage regulator (4)...
