Hard pressing board, hard pressing board remote control system and method

Abstract

Embodiments of the present invention provide a rigid platen, a rigid platen remote control system and method, wherein the rigid platen includes a motor, a platen connecting piece, a platen seat, a protective screen, a return spring, a screw rod, a bracket and a telescopic locking mechanism. The invention converts the rotating action of the motor into actions such as pushing out, rotating 90 degrees, and pulling back the connecting pieces of the hard pressing plate through the transmission cooperation among the components of the hard pressing plate, so as to realize the switching of the hard pressing plate between the throwing and the retreating. The connecting plate of the pressure plate rotates 90 degrees to open, and continues to rotate 90 degrees to close, the control process is simple, the workload of the operator is greatly reduced, and it is safe and reliable. In addition, the switching of the hard platen can be controlled manually to avoid the inability to control the state of the hard platen when the controller hardware fails. The hard platen remote control and method provided by the embodiments of the present invention can realize the remote control of the hard platen, avoid the remote control of the staff to the scene, save manpower, and facilitate the monitoring and verification of the hard platen.

Description

technical field [0001] The invention relates to the field of hard pressing plate control, in particular to a hard pressing plate, a hard pressing plate remote control system and method. Background technique [0002] The hard platen, also known as the protection platen, is a contiguous piece installed on the protective screen cabinet. Its closing and opening represent throwing and retreating. As the protection method of relay protection circuit, hard platen is widely used in the relay protection circuit of substation. The working state of the hard platen determines whether the control circuit is energized or not, which has a great impact on the safety of circuit maintenance work. [0003] At present, a large number of hard pressing plates need to be used in the power protection system to protect the signal on or off. For example, there are nearly 100 protective screens in a 220kV substation, and most of the protective screens have dozens of hard pressing plates. Checking the...

AI Technical Summary

Problems solved by technology

For example, there are nearly a hundred protective screens in a 220kV substation, and most of the protective screens have dozens of hard pressure plates. Checking the status of the hard pressure plates one by one will cause heavy work for the substation operators

In the face of a huge workload, it is very easy for individual equipment to fail or the hard platen to fail to be detected in time, resulting in a major power accident
