Problems solved by technology
[0002] The power protection switch is to generate voltage when the neutral point shifts to the ground when an electric shock occurs, so as to make the protection action cut off the power supply. It protects the entire distribution transformer low-voltage network and has a large safety protection range. However, the traditional power protection switch It only has a separate switch function, the only thing is to protect the circuit and prevent the power supply from overloading. If the circuit fails, if the power supply protection switch fails internally, the circuit protection will not be realized. For this purpose, a power supply protection switch is designed.

The invention relates to an electric power supply protection switch, and the switch comprises a protection switch shell, a replaceable safety structure, a push-pull electric brake, a button electric brake, a wiring clamping piece and a clamping piece clamping bolt; the replaceable safety structure is arranged at the left rear side of the top surface of the protection switch shell, and the button electric brake is arranged at the left front side of the top surface of the protection switch shell; and the push-pull electric brake is arranged on the right side of the top surface of the protectionswitch shell. The arrangement of the circuit protection switch is optimized, the single structure of a traditional power supply protection switch is changed, the design of multi-stage disconnection protection is improved into the design of multi-stage disconnection protection, the power utilization safety is protected more effectively during installation and use, the push-pull type electric brakeis uniquely designed, and the closing structure of the electric brake is improved by changing one structure; in addition, paths designed at different horizontal heights are adopted inside, contact ofcross circuits is avoided, electricity safety is further improved, and application and popularization are facilitated.
