Description
Technical Field
The utility model belongs to the technical field of electrical overhaul, concretely relates to extension spring assembly and disassembly tools for circuit breaker operating device overhauls.
Background
The high-voltage circuit breaker is an electric appliance with contacts, and the purpose of opening and closing a circuit is achieved by opening and closing the contacts, so that the circuit can be completed only by depending on a certain mechanical operation system. The mechanical operating device outside the circuit breaker body is called an operating mechanism, and the transmission part connected between the operating mechanism and the movable contact of the circuit breaker is called a transmission mechanism and a lifting mechanism.
The method is characterized in that maintenance cycle requirements are provided for maintenance of breaker operating mechanisms A in 'power equipment maintenance test regulations' in the south, the maintenance cycle is set to 12 years, and the requirements are that 'when the maintenance cycle is limited by field conditions, overhaul is completed in a maintenance workshop in an integral rotation mode in principle', Guangxi power grid companies comb and analyze expired operations according to self conditions, and summarize reports of standardized maintenance of primary equipment of power transformation for three years are formed, the problem that the maintenance cost of joint venture breaker mechanisms A is high in the reports is most prominent, the core capability of independent maintenance of maintenance personnel of the companies is improved, the situation that the core skills are limited by people is broken away, the companies establish a subject attack and hardness group to carry out attack and hardness research on the independently completed joint venture breaker mechanism A, and related work of disassembly of breaker operating mechanisms is completed at present.
In the disassembly and overhaul operation of the circuit breaker operating mechanism, the disassembly and assembly work of the tension spring is often involved, and no particularly suitable tool is used for disassembling and assembling the tension spring at present.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a extension spring assembly and disassembly tools for circuit breaker operating device overhauls.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a tension spring disassembling tool for overhauling an operating mechanism of a circuit breaker mainly comprises a hook head, a straight rod and a nut; the hook head is fixedly arranged at one end of the straight rod, and the other end of the straight rod is provided with a groove; the nut is fixedly arranged on the straight rod.
Further, the hook head and the straight rod are connected in a threaded manner.
Further, the nut is arranged on the straight rod close to the groove.
The utility model discloses the beneficial effect who possesses:
the utility model has the advantages of simple structure and reasonable design, can satisfy the needs of circuit breaker operating device disintegration overhaul, the dismouting extension spring is quick simple, has improved work efficiency, has reduced operating time, has reduced the operation personnel simultaneously and has probably injured risk.
