[0002] Air switch test tool is used to test air switches. A circuit breaker is a switching device that can close, carry and interrupt current under normal or abnormal circuit conditions. Circuit breakers are important electrical devices for the protection and operation of power systems [3]. They can be used to distribute electrical energy, start asynchronous motors infrequently, and protect power lines and motors. There are many structures and types of circuit breakers, but they are basically composed of a conductive main circuit, insulating support components, arc-extinguishing chamber and operating mechanism. Circuit breakers are classified into high-voltage circuit breakers and low-voltage circuit breakers according to their application range.

[0003] For example, the authorized patent with publication number CN221100967U (Stable Air Switch Testing Device): its technical solution includes a propulsion cylinder, a mounting platform, a fixing platform, a connecting seat, and a contact assembly. The propulsion cylinder is installed on one side of the fixing platform, and the connecting seat is installed on the top of the fixing platform. Contact assemblies are installed on both sides of the top of the connecting seat. A base plate is disposed within the contact assembly. A spring sheet is welded to one side of the base plate. A connecting plate is installed on the side of the spring sheet away from the base plate, and an arc-shaped plate is installed on the side of the connecting plate away from the spring sheet. This utility model, by installing an arc-shaped plate on one side of the connecting plate, allows the arc-shaped plate to contact the contacts inside the air switch. The elastic force ensures a tight connection between the arc-shaped plate and the inside of the air switch, guaranteeing the stability of the device during operation and preventing the detection device from disconnecting from the air switch, thus affecting the detection effect.

[0004] The testing devices described above are not comprehensive enough, cannot perform a full visual inspection of air switches, and are not convenient to use, as they cannot be controlled by a test pen and ammeter, and are not flexible enough in operation. Utility Model Content
