Description

Technical Field

[0001] This utility model belongs to the field of relay protection technology, specifically a device for preventing accidental contact with relay protection pressure plates. Background Technology

[0002] Relay protection circuit boards are an important control element in power systems. They enable or deactivate relay protection devices through physical or electronic means, serving as the first line of defense for ensuring the safe and stable operation of the power grid.

[0003] The relay protection pressure plate consists of a pressure plate body, an indicating device, and connecting terminals. The pressure plate body is usually made of metal, which has good conductivity and mechanical strength. It is used to connect circuits and withstand operating forces. The working principle of the relay protection pressure plate is that when the pressure plate is in the engaged state, the circuit it is connected to is conducting, allowing the relay protection device to receive signals and execute corresponding protection actions. When the pressure plate is in the disengaged state, the circuit is disconnected, the relay protection device is isolated, and it cannot protect the power system. The state is usually changed by rotating and pushing / pulling the handle of the pressure plate, thereby realizing the control of the protection function.

[0004] In existing relay protection pressure plate technology, the exposed handle is easily subjected to external force, which can change the state of the relay protection device and thus affect the working state of the relay protection.

[0005] Therefore, this utility model provides an anti-accidental contact device for relay protection pressure plates. Utility Model Content
