Description

Technical Field

[0001] This utility model belongs to the technical field of relay protection devices, and in particular, it relates to a relay protection device. Background Technology

[0002] Relay protection devices are key equipment in power systems, used to quickly disconnect faulty circuits when a power grid fault occurs, thereby protecting the safe and stable operation of power equipment and systems. Currently, the main unit of a relay protection device is usually installed in a distribution box or control cabinet and fixed to the mounting bracket or guide rail of the box by bolts.

[0003] However, existing fixing methods have the following drawbacks:

[0004] (1) Inconvenient disassembly: When bolts are used for fixing, special tools are required for installation and disassembly, which is cumbersome. Especially in environments with limited space or insufficient light, the disassembly efficiency is low, which increases the time cost of maintenance and replacement.

[0005] (2) Low maintenance efficiency: When equipment needs to be repaired or replaced, the bolts need to be loosened one by one. If the bolts are rusted or stripped, it will further increase the difficulty of disassembly and affect the rapid restoration of the power system.

[0006] (3) Poor adaptability: Different models of relay protection device main units may need to be matched with different mounting hole positions. If the cabinet structure is not standardized, there may be installation incompatibility problems when replacing new equipment. Utility Model Content
