According to the requirements of relevant regulations, it is necessary to regularly check the status of substation equipment, especially to conduct safety inspections on the relay protection outlets of substations. The relay protection detector is a universal test device for relay protection, which is mainly used for testing and researching various types of electromagnetic, integrated circuit and microcomputer protection relays and protection systems of various voltage levels. It can realize flexible control of voltage and current amplitude, phase frequency, and has special test modules for various relays and protections. It is an essential tool for commissioning and regular inspection of protection devices of power grassroots units before commissioning.

[0003] In the prior art, generally when conducting safety inspections on the relay protection outlets of substations, the multimeter does not have a temporary fixing structure, which makes installation inconvenient, reduces detection efficiency, and affects use. It is installed by adsorption with the shell of the relay protection equipment through a strong magnet, and can only be used for equipment with a magnetic shell. In addition, the strength of the strong magnet is difficult to control, resulting in poor stability of the multimeter and easy sliding. The traditional fixing structure cannot fix multimeters of different sizes, and its practicality is low. Utility Model Content
