Description
Technical Field
The utility model relates to a circuit breaker overhauls supplementary multiplexer utensil, concretely relates to an assembly and disassembly tools that is arranged in 10kV to put cabinet circuit breaker energy storage spring.
Background
The 10kV centrally installed switchgear circuit breaker generally adopts a spring energy storage mechanism, and currently, the circuit breaker is commonly in models such as Senyuan VS1, Pa Weier WEP, general VB2 and east VED 4. The existing common breaker of the centrally installed switchgear adopts 2 types of energy storage spring structures and installation forms, one type is a bare spring, and hook-shaped structures or installation holes at two ends of the spring are directly connected with a breaker mechanism; the other type is that the two ends of the spring are arranged in the clamping sleeve and then are connected with the circuit breaker mechanism through a hook or a mounting hole of the clamping sleeve. When internal elements (such as a closing coil, an energy storage motor or an internal transmission connecting rod and the like) of the circuit breaker break down and need to be repaired and replaced, the energy storage spring is detached after releasing energy, and then the next step of pertinently detaching the fault elements can be carried out; even if the energy storage spring is in an energy release body, the energy storage spring is actually in a pre-stretching state, has great energy and is not easy to disassemble; when the energy storage spring is reassembled, the shaft pin can be installed only by stretching the energy storage spring for a certain distance, and the energy storage spring cannot be stretched by bare hands. Therefore, the tools for assisting the disassembly and assembly of the energy storage spring of the circuit breaker are researched frequently, for example, the Chinese patent document with the publication number of CN202656147U discloses a spring disassembling and assembling tool of a scissor type vacuum circuit breaker, the lower structure of the clamp handle is close to the structure of the scissor blade, when the energy storage spring is disassembled and assembled by the tool, the energy storage spring disassembling and assembling tool clamps the energy storage spring on the spring operating mechanism of the vacuum circuit breaker, then the handle is rotated to make the clamping frame move downwards, so that the clamping handles of the disassembling tool move oppositely until the blade-shaped part at the lower part of the clamping handle is embedded into the gap of the spring, the energy storage spring is pushed towards the two ends to overcome the pretension force of the energy storage spring, so that the energy storage spring is jacked and stretched, the device can accomplish the effect of clamping spring through the handle rotation, but with the spring to both sides tensile, the effect is not too obvious, and is harder during the use moreover. For another example, chinese patent document No. CN207522519U discloses a tool for disassembling, assembling and repairing an energy storage spring of a vacuum circuit breaker, which must hook the spring in advance when in use, but for a spring in a release state, the hook portion of the spring cannot be put into the spring, and the use of the tool has obvious limitations. For another example, chinese patent document No. CN207344505U discloses an energy storage spring replacer for a switch cabinet circuit breaker, however, the device must be provided with a stressed position at both ends of a target spring for removal, and the energy storage spring in the switch cabinet circuit breaker is generally a bare spring and has no stress point, so that the applicability is greatly limited.
By the aforesaid can know, the dismouting multiplexer utensil that is arranged in putting cabinet circuit breaker energy storage spring among the prior art generally only uses and designs to the dismouting of the energy storage spring of a certain specific model or type, however in the electric wire netting each manufacture factory design structure of the cabinet circuit breaker energy storage spring of adoption and actual layout are different, the energy storage spring size of adoption is also different, the commonality of current dismouting multiplexer utensil is not strong, can not be applicable to the supplementary dismouting of different models and structure circuit breaker energy storage spring.
