Description

High-voltage fuse mounting structure convenient to quick replacement Technical Field The utility model relates to the technical field of power equipment, in particular to a high-voltage fuse mounting structure convenient for quick replacement. Background In a power system, a high-voltage fuse is used as an important protection device and is widely applied to overload and short-circuit protection of equipment such as transformers, motors, capacitor banks, switch cabinets and the like. The core function is that when the current in the circuit exceeds the rated value, the melt melts due to heat, so that the circuit is cut in an extremely short time, and the back-end equipment is protected from damage. In the prior art, a conventional high-voltage fuse mounting structure usually depends on fastening a plurality of screws, an operator is required to screw or loosen the plurality of screws one by one in the process of disassembly and installation, the operation is complicated and the efficiency is low, particularly, when working aloft, the plurality of screws are positioned at different positions, the disassembly difficulty of the operator is increased, the operator is required to continuously adjust the posture and the angle of the body to disassemble all the screws, and each movement of the body in the aloft work is accompanied with safety risks, such as the operator may need to extend the body out of a safety range when trying to screw or loosen the screws positioned at the bottom or the top, and the falling risk is increased.
