Modularized combined type multi-position disconnecting switch

Abstract

The invention discloses a modularized combined type multi-position disconnecting switch which is characterized in that an operating handle is fixed at one end of a main rotating shaft through a handle rod, and a moving contact cam is mounted on a shaft body of the main rotating shaft; the locking pins respectively lock the operating handle at different rotating positions, and the operating handle can be unlocked by the locking pins by controlling the handle ball; the contact group is installed in the switch frame, and the moving contact cam can shift the contact group at the corresponding position in the rotation process so as to adjust the contact state of the contact group. And the combination of the angle of the moving contact cam corresponding to the preset contact group relative to the main rotating shaft and the contact state of the contact group stirred by the moving contact cam conforms to the preset switch state of the current rotating position. According to the technical scheme, circuit switching of multiple rotation position states is achieved, the size of the disconnecting switch is greatly reduced, a complicated structural system is modularized and integrated, and operability and maintainability of the disconnecting switch are greatly improved.

Description

technical field [0001] The invention relates to the technical field of isolating switches, in particular to a modular combined multi-position isolating switch. Background technique [0002] At present, the control element in the isolation switch system is to control the on-off of the contacts. The rail vehicle can meet the different power supply requirements of the vehicle in the normal position, the workshop power position and the ground position under control or under interference conditions. The existing isolation switch structure It is complex, has a wide variety, and is generally designed with custom design. There is no unified structural design requirement, and there are few common parts, which increases the design difficulty, manufacturing cost and maintenance cost. It cannot meet the requirements of rapid response to customer plans, energy saving and environmental protection. SUMMARY OF THE INVENTION [0003] In view of the above problems, the present invention pro...

[0002] At present, the control element in the isolating switch system is to control the on-off of the contact. The rail vehicle can meet the different power supply requirements of the vehicle in the normal position, the workshop power position and the grounding position under control or interference. The existing isolating switch structure Complicated, with a wide variety, custom designs are commonly used, there is no unified structural design requirement, and there are fewer common parts, which increases design difficulty, manufacturing cost and maintenance cost, and cannot adapt to the requirements of quick response to customer solutions, energy conservation and environmental protection
