[0002] A substation is a place in the power system where voltage and current are transformed, electric energy is received and distributed. There are a large number of lines in the substation, and the normal use of these lines is the basis for the smooth operation of the substation. Using protectors to detect the use of wires and provide safety protection is a common method.

[0003] When installing the existing protector, the most common method is to drill a hole in the shell of the protector and then fix the protector on the mounting surface by bolts. However, this method has certain disadvantages. First, drilling a hole in the shell will affect the integrity of the shell and reduce the strength of the shell. When tightening the bolts, it is easy to cause the shell to deform or even break due to excessive force. Secondly, personnel need to regularly inspect, maintain or replace the protector, so they need to disassemble and assemble the bolts one by one, which is inefficient and inconvenient. Therefore, it is necessary to design a new protector to solve this problem. Utility Model Content
