Electricity driving operation/exit apparatus for protection pressing board

Abstract

The invention discloses an electric throwing and backing device for protecting a pressure plate, which comprises a pressure plate connecting sheet, a pressure plate base, a position checking bracket, a drum cover, and a magnet steel column, a lifting column, a straight edge rebounding ring, a bevel edge thrust ring, an E-type spacing collar and a drive motor which are mounted inside the drum cover. The device transforms the whirling action of the driving motor into the release, the whirl, the pullback and other movement of the pressure plate connecting sheet through driving the drive motor and the transmission coordination of all internal components, so that the throwing and the backing movements of the pressure plate are transformed. The device has the advantages of simple and reasonablestructure, lower production cost, convenient operation and use, good throwing and backing property and reliable mechanical breakpoint.

Description

technical field [0001] The invention relates to an automatic input and withdrawal device of a pressure plate, in particular to an automatic input and withdrawal device of a pressure plate in a power system protection cabinet. Background technique [0002] At present, a large number of protective pressure plates are required in the power protection system to switch on or off the protection signal. Since many substations are currently unattended stations, it is often necessary to go to the substation in order to return one or several pressure plates, which is inconvenient to operate and causes a lot of manpower and material resources consumption. Some protection manufacturers provide software pressure plates in their protection systems, which can automatically switch on and off through microcomputer protection, but because the software pressure plates cannot provide obvious mechanical disconnection points, the power system cannot be used with confidence.

Problems solved by technology

Since many substations are currently unattended stations, it is often necessary to go to the substation in order to return one or several pressure plates, which is inconvenient to operate and causes a lot of manpower and material resources consumption.

Some protection manufacturers provide software pressure plates in their protection systems, which can realize automatic switch-on and withdrawal through microcomputer protection, but because the software pressure plates cannot provide obvious mechanical disconnection points, the power system cannot be used with confidence
