Dismounting tool used for breaker mechanism energy storage spring

Abstract

The invention discloses a dismounting tool used for a breaker mechanism energy storage spring. The tool comprises a connecting rod, a first clamping plate and a second clamping plate. Two ends of the connecting rod are provided with screw thread segments with opposite rotation directions. The first clamping plate is provided with a first screwed hole and is installed on one end of the connecting rod through the first screwed hole. The second clamping plate is provided with a second screwed hole and is installed on the other end of the connecting rod through the second screwed hole. The tool possesses advantages that the structure is simple; making is convenient; and mechanism energy storage spring dismounting efficiency can be effectively increased and so on.

Description

technical field [0001] The invention relates to a maintenance tool for a power system, in particular to a disassembly tool for an energy storage spring of a circuit breaker mechanism. Background technique [0002] Circuit breakers, especially 10kV vacuum circuit breakers, are widely used in power systems, and there are many types of mechanism failures. The most common and typical troubleshooting is the replacement of coils and energy storage motors. When replacing coils and energy storage motors, the mechanism needs to be removed Energy storage springs and other components can be carried out. Such as figure 1 with figure 2 As shown, the structural design of most circuit breakers is very compact. The energy storage spring 1 of the mechanism is installed and positioned by the fixing plates 2 at the upper and lower ends. The space on the left and right sides of the energy storage spring 1 of the mechanism is very narrow. The disassembly and assembly of the energy storage sp...

Problems solved by technology

like figure 1 and figure 2 As shown, the structural design of most circuit breakers is very compact. The energy storage spring 1 of the mechanism is installed and positioned by the fixing plates 2 at the upper and lower ends. The space on the left and right sides of the energy storage spring 1 of the mechanism is very narrow. The disassembly and assembly of the energy storage spring 1 is very difficult and the efficiency is very low, which greatly reduces the quality of maintenance. Sometimes it is necessary to contact the manufacturer's personnel to deal with it, resulting in the failure of the circuit breaker to be eliminated in time, which seriously affects the normal operation and service quality of the power system.
