Description

Technical Field

[0001] This utility model belongs to the field of hard pressure plate protection, specifically relating to a hard pressure plate anti-accidental collision protective cover. Background Technology

[0002] Protection circuit breakers include rigid and flexible circuit breakers. They serve as a bridge and link between relay protection devices and automatic devices, connecting them to external wiring. They are crucial for the realization of protection functions and the proper functioning of the action outputs. Changes in power system operation often involve the activation or deactivation of circuit breakers. Accidental activation or deactivation, or even accidental contact with a rigid circuit breaker, can directly affect the relay protection function. In severe cases, it can cause protection failure or malfunction, leading to power equipment burnout or widespread power outages, thus impacting the safe operation of the power grid.

[0003] To address this, Chinese Patent CN205811285U discloses a protective cover for preventing misoperation of a pressure plate, comprising a cover body, an arc edge A, an arc edge B, and a side baffle connecting arc edge A and arc edge B. The cover body is a semi-enclosed waist-shaped structure, with arc edge A and arc edge B respectively provided at the arc on the back of the cover body. The cover body and the protected pressure plate are fastened together by the staggered arc edges and arc edge A to form a semi-enclosed inner cavity. This semi-enclosed inner cavity seals the pressure plate screws and the pressure plate connecting piece inside, and the pressure plate screws are connected by the pressure plate connecting piece.

[0004] However, this anti-misoperation protective cover still has the following problems: It adopts a semi-enclosed design, which has certain limitations in protection; when workers accidentally come into contact with the metal part of the protective pressure plate during operation, they face the safety risk of electric shock.

[0005] The enclosure is a semi-enclosed, waist-shaped structure, which is prone to loosening and detachment, and cannot effectively protect the equipment from temperature and safety issues during operation.

[0006] In view of the above, this utility model is hereby proposed. Utility Model Content
