Description

Technical Field

[0001] The utility model relates to the technical field of relay protection pressure plates, in particular to a dustproof protective cover for a relay protection pressure plate of new energy equipment. Background Art

[0002] The relay protection pressure plate is a kind of power equipment, which is mainly used for centralized control of protection relays. In the power system, the relay protection pressure plate is widely used in various electrical equipment, such as generators, transformers, line protection, etc. Its performance and reliability are crucial to the safe operation of the power system. Therefore, when selecting and applying it, it is necessary to consider many factors such as electrical performance, mechanical strength, insulation level, etc. to ensure the quality and reliability of the relay protection pressure plate.

[0003] The relay protection pressure plate plays the role of connecting and disconnecting in the protection circuit, which is equivalent to a switch. By putting in or out of the corresponding protection function, precise control of the power equipment can be achieved. For example, when the pressure plate of the quick-break protection is turned on, if the load of the switch cabinet is short-circuited, the switch will not trip, which may cause over-tripping and large-scale power outages. Therefore, in actual operation, it is necessary to operate the relay protection pressure plate with caution to avoid safety accidents caused by misoperation. However, when the existing relay protection pressure plate is in use, there is no corresponding structure to protect it. The relay protection pressure plate is directly exposed to the outside. When in use, it may be affected by the external environment and cause collision damage to it, thereby causing damage to it. Utility Model Content
