Problems solved by technology
If numerous protective pressure plates are put in or out by mistake, it will affect the normal signal transmission of the relay protection device, making it impossible for the power monitoring background to obtain on-site information correctly, and it will cause the relay protection device to malfunction or refuse to operate, seriously threatening the power grid safe operation
In the process of regular maintenance of the power system, it often happens that some pressure plates are frequently switched on and off and some pressure plates are fixed.
[0003] The existing power system relay protection operation and maintenance regulations require that the switching on and off of the pressure plate is managed by the operating personnel, and part of it is open to the maintenance personnel during maintenance. There is a phenomenon of double management, which increases the risk of misoperation

Embodiment Construction
[0026]Such asfigure 1 As shown, a relay protection pressure plate based on a magnetic lock is configured by a block cover, a magnetic lock, a controller, and a keyboard indicating four parts, and the block cover is mainly used to cover the protective device pressure plate, prevent errors, Made from the transparent plastic material, it can be observed through the pressure plate to observe the retraction of the pressure plate; the magnetic lock is used to force the pressure plate to prevent the device to be strongly adsorbed on the pressure plate mounting plate; the controller is mainly used to control the magnetic lock suction, accept the keyboard The operation command and the current device status; the keyboard is displayed as a human-machine operation interface, and the password input can be received by the keyboard, the opening and closing of the control device's magnetic lock, the opening and closing state can also be set by the keyboard setting device. Specifically, the relay pr...

The invention provides a relay protection pressing plate anti-misoperation device and method based on a magnetic lock, and the device comprises a pressing plate cover which is used for covering a protection device pressing plate and preventing misoperation, a magnetic lock used for strongly adsorbing the pressing plate anti-misoperation device to a pressing plate mounting plate, a controller used for controlling the suction force of the magnetic lock, receiving an operation command and indicating the current device state, and a man-machine interaction module used for receiving password input, performing an opening and closing operation command of the magnetic lock, displaying an opening and closing state and setting an unlocking password of the device. According to the invention, the problem of misoperation of the relay protection pressing plate in the operation and maintenance process is solved.
Description
Technical field[0001]The present invention belongs to the technical field of power system safety, which is specifically related to a relay protection pressure plate arranging by a magnetic lock-based locking device and method.Background technique[0002]The relay protection device is an indispensable safety protection device that power system, and various relay protection devices are equipped with protective pressure plates for relaying protection and derivation brakes for devices. It is generally protected on the switchgear to protect the platen, and some normal runtime is in the input state, some are in the exit state, and some of the platens are only in the input state when overhaul. If a large number of protective platen occurs, if you exit, you will make the normal signal transmission of the relay protection device, so that the power monitoring background cannot obtain the field information correctly, and the relay protection device is mishaped or refused, and severely threatened...
