Pressing plate anti-misoperation cover for relay protection test

Abstract

The invention provides a pressing plate anti-misoperation cover for a relay protection test, and relates to an anti-misoperation device. When the relay protection test is conducted in an incomplete power failure state, careful confirmation is needed, once misoperation is generated, primary equipment of a power substation is tripped, and even the whole substation loses power. The pressing plate anti-misoperation cover comprises an anti-misoperation cover body and an anti-misoperation cover fixing frame. The anti-misoperation cover body is detachably connected to the anti-misoperation cover fixing frame and is a transparent insulator shaped like a left square bracket, and the anti-misoperation cover body comprises a front plate, connecting plates located on the upper side and the lower side of the rear face of the front plate, positive electrode conductors and negative electrode conductors. Light sources are embedded into the middle of the front plate, the positive electrode conductors and the negative electrode conductors are connected to the upper sides and the lower sides of the light sources respectively, the tail ends of the positive electrode conductors and the tail ends of the negative electrode conductors are located on the connecting plates, and the anti-misoperation cover fixing frame is of a hollow square shape and provided with a power source, a positive electrode connecting end and a negative electrode connecting end, wherein the positive electrode connecting end is connected with the positive electrode of the power source, the negative electrode connecting end is connected with the negative electrode of the power source, and the positive electrode connecting end and the negative electrode connecting end are respectively of a long strip shape. By the adoption of the technical scheme, safety of the relay protection test is guaranteed.

Description

technical field [0001] The invention relates to an anti-misoperation device. Background technique [0002] At present, in the relay protection test of the conventional power system, for the relay protection test in the state of incomplete power failure, the operation status of the relay protection pressure plate needs to be carefully confirmed. All the equipment trips, and in serious cases, it will cause the power failure of the whole station. Contents of the invention [0003] The technical problem to be solved and the technical task proposed by the present invention are to perfect and improve the existing technical solutions, and to provide a pressure plate error-proof cover for relay protection tests, so as to avoid misoperation. For this reason, the present invention takes the following technical solutions. [0004] A pressure plate anti-mistake cover for relay protection test, characterized in that it includes an anti-mistake cover body and a fixed frame for the ant...
