Embodiment Construction

[0011] The present invention will be further described below in conjunction with accompanying drawing:

[0012] Such as figure 1 and figure 2 As shown, the installation screen 3 is to install the protective screen screen of the present invention, and a plurality of throwing and withdrawing devices can be installed on it. The plate connecting piece 1 of the device is plugged on the plate base 2 and electrically connected with the plate base 2. The fixing columns of the plate base 2 pass through the round holes on both sides of the installation screen 3, and the top of the position detection bracket 5 is fixed by nuts. both sides of the face. The fixing rod of the pressure plate connecting piece 1 passes through the pressure plate seat 2, the middle hole of the installation screen 3, the inner circle cavity of the position detection bracket 5 and the magnetic steel column 6 in order downwards, and the magnetic steel column 6 is connected with the magnetic steel column 6 below...

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 reasonable structure, 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. Contents of the inve...
