Description

Technical Field

[0001] The utility model relates to the technical field of quality inspection equipment. More specifically, the utility model relates to a power circuit breaker detection device. Background Art

[0002] When a power circuit breaker enters the factory for inspection, due to the lack of professional detection equipment, generally only the appearance quality can be inspected. If the appearance quality is qualified, the product is put into storage, and the power circuit breaker is used as a qualified product for assembly and wiring on an electrical output control cabinet.

[0003] The product output control cabinet has no function of opening and closing the circuit breaker and displaying the state. These functions are operated and displayed on an electrical control panel. In this case, it is necessary to wait until the electrical system of the product is wired before conducting a power supply inspection test on the functions and states of the circuit breaker in the output control cabinet.

[0004] During the product system inspection process, if the power circuit breaker cannot be closed, it is necessary to find the reasons from multiple places. However, since the multiple circuit controls are interconnected, it is very difficult to find the real reason why the power circuit breaker cannot be closed. Due to the above reasons, the ineffective inspection of multiple power circuit breakers has a great impact on the later work, wasting time and labor and delaying the product delivery period.
