A protective hard pressure plate with outlet and function simultaneous throwing and withdrawing

Abstract

A protective hard pressure plate with an outlet and a function of simultaneous throwing and withdrawing of the present invention includes a first contact, a second contact, a contact mounting support, a connecting piece, and a connecting piece mounting support; the connecting piece mounting support It includes an upper end support, a lower end support and a bearing bracket; the contact mounting support includes a beam, a first carrier plate, a second carrier plate and a hanging plate; the second contact is provided with moving parts for relatively The second carrier board moves vertically; the lower end support is provided with an adjustment component for adjusting the initial movement position of the plectrum relative to the connecting piece during the synchronous movement of the plectrum and the connecting piece. The beneficial effect of the present invention is embodied in that the setting of the adjustment part in the connecting piece mounting support is used to adjust the initial movement position of the relative connecting piece during the synchronous movement of the picking piece and the connecting piece, and provide different working states of the picking piece under different environmental uses The gear position is convenient for the operator to operate, not only realizes the function and the synchronous operation of the outlet hard pressure plate, but also realizes the special operation of a single input of the outlet connecting piece.

Description

technical field [0001] The invention belongs to the field of electric power grids, and in particular relates to a protective hard pressing plate for simultaneous switching on and off of outlets and functions. Background technique [0002] At present, the protective pressure plates used in substations can be divided into outlet pressure plates and functional pressure plates. Among them, the outlet pressure plate is directly related to the reliable outlet tripping of the circuit breaker on this side or other sides; the function pressure plate realizes protection functions, such as main transformer protection, distance protection, zero protection and other protection functions such as switching and withdrawing. There are many protection outlets and function pressure plates on the protection screen cabinet of the substation. It is inevitable that the operator will miss the protective outlet or the function pressure plate during the operation process, that is, the protection outl...

AI Technical Summary

Problems solved by technology

There are many protection outlets and function pressure plates on the protection screen cabinet of the substation. It is inevitable that the operator will miss the protective outlet or the function pressure plate during the operation process, that is, the protection outlet and the function pressure plate are not put in at the same time, which will cause the protection or the switch to refuse to move. etc., bringing great safety hazards to the safe operation of primary and secondary substation equipment
