Pressure plate port voltage measuring meter of relay protection system

The utility model provides a pressure plate port voltage meter of a relay protection system, and relates to the technical field of voltage meters. The gear selection button is provided with a contact, and the gear selection button is rotatably connected with the protective shell; the integrated circuit board is fixedly installed in the protective shell, and a plurality of contacts are arranged at the positions, making contact with the gear selection button contacts, of the integrated circuit board; and the insulating layer is arranged in an area, opposite to the gear selection button, on the integrated circuit board and covers a part of the plurality of contacts on the integrated circuit board. According to the utility model, the problem that when a universal meter is used for measuring the voltage of the port of the pressing plate of the relay protection system, if the gear selection is wrong, the direct current system is grounded or the protection equipment malfunctions is solved. 本实用新型提供一种继电保护系统压板端口电压测量表，涉
