Problems solved by technology

[0002] In machinery, metallurgy, military industry and other industries, circuit breakers play a very important role. The circuit breaker can not only connect, carry and break the current under normal circuit conditions, but also can connect and carry the current under the specified abnormal conditions. For a certain time and breaking current, when the circuit is under abnormal conditions, the circuit breaker must be able to make a reasonable response according to the user's needs. The existing tests on low-voltage electrical appliances can only be limited to the functions of traditional low-voltage electrical appliances. Due to the test equipment, it is impossible to complete the test of all functions under the existing conditions

Embodiment Construction

[0010] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0011] As shown in the figure, a low-voltage electrical appliance detector is mainly composed of an industrial computer, a PLC module, a data acquisition module, a signal transmitter, a sensor module, and a thyristor controller. The sensor module detects low-voltage electrical appliances and transmits them to the signal acquisition module through the signal transmitter. The PLC module is connected to the relay cabinet, and the relay cabinet controls the DC motor, voltage gear and switch.

[0012] The system is also provided with a manual switch and a status display, which can manually operate the l...
