Description

Technical Field

[0001] The utility model relates to the technical field of circuit breakers, in particular to a maintenance tool for high-voltage circuit breakers. Background Art

[0002] There are many types of mechanisms used in high-voltage circuit breakers, such as pneumatic mechanisms, electromagnetic mechanisms, hydraulic mechanisms, electric mechanisms, and spring mechanisms. However, in actual operation, spring mechanisms are the most common. Spring mechanisms mainly use motor energy storage to stretch or compress springs to provide energy. From the perspective of operation, this type of mechanism is more reliable than other mechanisms. In recent years, with the transformation and upgrading of substations, the operating mechanisms commonly used in vacuum circuit breakers of central high-voltage cabinets are all spring energy storage operations. However, when the spring energy storage operating mechanism fails during use and the energy storage spring needs to be disassembled and assembled, the spring pressure value reaches about 30kN, which is quite difficult to disassemble and assemble. The existing disassembly and assembly of energy storage springs is time-consuming and labor-intensive, and the operation is relatively difficult.

[0003] At present, when a screwdriver is inserted into the gap between the springs and used with the tying wire to tie the tension spring, the screwdriver may slip and the tying wire may break, causing injuries. In addition, since the sizes of the energy storage springs in various types of high-voltage switch cabinets are different, simple tools of different sizes need to be made. Therefore, the simple tools are not universal. There is no protection in the middle when disassembling the energy storage spring, and it is relatively laborious to fix and clamp the two ends of the spring. In this regard, the utility model provides a maintenance tool for a high-voltage circuit breaker. Utility Model Content
