Description

Technical Field

[0001] The present invention relates to the technical field of disconnect switches, and in particular to a disassembling and assembling device for an elastic component of a disconnect switch. Background Art

[0002] A disconnect switch is a switching device mainly used for "isolating power sources, performing switching operations, and connecting and disconnecting small-current circuits" without arc-extinguishing function. When the disconnect switch is in the open position, there is an insulating distance that meets the specified requirements and an obvious disconnection mark between the contacts; when in the closed position, it can carry the current under normal circuit conditions and the current under abnormal conditions (such as short circuit) within a specified time. Generally used as a high-voltage disconnect switch, that is, a disconnect switch with a rated voltage above 1 kV, its working principle and structure are relatively simple, but due to the large usage amount and high requirements for working reliability, it has a greater impact on the design, establishment, and safe operation of substations and power plants. The main feature of a disconnect switch is its lack of arc-extinguishing ability, and it can only disconnect and connect the circuit without load current.

[0003] Generally, most disconnect switches are provided with elastic components such as springs or elastic pieces for resetting. When disassembling and assembling the elastic components, the elastic components need to be compressed or stretched. Currently, generally, the elastic components are compressed or stretched directly by hand or using tools such as pliers to complete the disassembly and assembly steps. Using the above methods to disassemble and assemble the elastic components has the following disadvantages: it is very labor-intensive; the elastic components may be damaged due to excessive force; it is possible to cause personal injury when disassembling and assembling due to not grasping the elastic components tightly; the elastic force of the elastic components cannot be accurately controlled. Summary of the Invention
