Press plate shunting device

Abstract

The invention provides a press plate shunting device. The press plate shunting device comprises a base, a plurality of movable covers and an interlocking sheet, wherein the base is arranged in a way that a plurality of press plates are encircled, the plurality of movable covers and the plurality of press plates are arranged on the base in one-to-one correspondence, the plurality of movable coversare movably connected with the base, the plurality of movable covers are used for matching with the base during buckling to form a plurality of accommodating spaces so as to accommodate the press plates, and the interlocking sheet is matched with the base and is used for pressing the movable covers needed to be shunted in parallel in the plurality of movable covers after the plurality of movable covers are buckled so that the movable covers needed to be shunted in parallel are closed. The press plate shunting device is convenient to install and simple to operate, the movable covers corresponding to the press plates needed to be shunted in parallel can be arranged below the interlocking sheet, parallel shunting is performed, the movable covers corresponding to the press plates independentlyshunted are arranged above the interlocking sheet and are independently shunted, so that the workload of an operator is reduced, and the press plate shunting device is flexible and is easy to use.

Description

Technical field [0001] The present invention relates to the field of electric power, in particular to a pressure plate locking device. Background technique [0002] The relay protection device in the secondary equipment of the power system is the basic equipment to ensure the safe operation of the electric primary equipment. The secondary equipment of the substation is increasing with the improvement of the degree of automation. Therefore, the misoperation of the secondary equipment is gradually increasing. The correct input and withdrawal of the pressure plate is an important guarantee for the protection of the secondary equipment. [0003] However, in the traditional power system, the secondary pressure plate generally does not have the function of preventing errors. The operation of the secondary pressure plate is only based on the experience of the operation and maintenance personnel. The operation and maintenance personnel will control the operation ticket and record it in rea...

Problems solved by technology

[0003] However, in the traditional power system, the secondary pressure plate generally does not have the function of error prevention. The operation of the secondary pressure plate only depends on the experience of the operation and maintenance personnel. The anti-misoperation measures of the pressure plate generally only take some measures in management, such as standardized double naming, color code management, and installation of anti-mis-collision covers, etc., which cannot fundamentally prevent operators from going to the wrong interval and reversing the operation sequence. Misoperations caused by other behaviors cannot realize the forced locking of the secondary pressure plate, and fundamentally solve the problem of preventing mistakes such as mis-input, mis-return, missed throw, and missed return of the secondary equipment.
