Abstract
The utility model discloses a directly operated grounding switch of a solid insulation ring main unit. The switch comprises an epoxy resin soleplate; a grounding static contact and an intermediate static contact are arranged in the epoxy resin soleplate; a moving contact is arranged in the epoxy resin soleplate; back and forth movement of the moving contact realize conductive connection or break of the grounding static contact and the intermediate static contact; a rear end of the moving contact is connected with an insulation pull bar; an operation terminal of the insulation pull bar extends out of the epoxy resin soleplate through a guide sleeve at a rear end of a insulation shell. The above structure can change a rotation movement of a traditional grounding switch into linear motion, and the moving contact is in a rod structure, which offers a stable conductive contact performance, so as to make the movement more directly, save the space occupied by the moving contact; meanwhile, the motion state can be judged directly through the length of the insulation pull bar extending out of the insulation shell, thereby eliminating the safety hidden troubles.
Description
Technical field
The utility model relates to a kind of earthed switch, specifically a kind of solid insulation ring main unit Direct Action Type earthed switch.
Background technology
AC high voltage ground switch in the existing high-tension distribution equipment, its moving contact is for rotatablely moving, and dynamic/static contact mainly adopts the incision structure of blade type; Existing this structure is so that the conductive contact unstable properties of dynamic/static contact, and the overall space size is large, is unfavorable for the requirement of equipment for power transmission and distribution miniaturization.
Summary of the invention
The technical problems to be solved in the utility model provide a kind of simple and compact for structure, to take the overall space size little, the solid insulation ring main unit Direct Action Type earthed switch of conductive contact stable performance.
In order to solve the problems of the technologies described above, solid insulation ring main unit Direct Action Type earthed switch of the present utility model, comprise the epoxy resin mount pad, be provided with grounding static contact and a middle fixed contact that is positioned at epoxy resin mount pad mid portion that is positioned at epoxy resin mount pad front end in the epoxy resin mount pad, also has a moving contact that also can in the epoxy resin mount pad, move forward and backward with fixed contact and the coaxial setting of middle fixed contact in the epoxy resin mount pad, the moving forward and backward of moving contact can make grounding static contact and middle fixed contact conduction be connected or disconnect, the rear end of moving contact is connected with one and thoroughly does away with the edge pull bar, and the operating side of insulated tension pole reaches outside the epoxy resin mount pad by the guide pin bushing that is positioned at the insulation shell rear end.
Be provided with fixed contact in the described grounding static contact, the front end of moving contact is provided with an auxiliary contact that matches with the fixed contact of fixed contact.
Be provided with spring touch finger in the fixed contact in the middle of described.
After adopting above-mentioned structure, because the grounding static contact and the middle fixed contact that arrange in the epoxy resin mount pad, also has a moving contact with fixed contact and the coaxial setting of middle fixed contact in the epoxy resin mount pad, arrange thus and can change rotatablely moving of traditional earthed switch into rectilinear motion, and moving contact is club shaped structure, so that the conductive contact stable performance of dynamic/static contact, make thus its motion more direct, saved the shared space of moving contact action, be conducive to the miniaturization requirement of transmission facility, also can stretch out the outer length of insulation shell by insulated tension pole simultaneously and directly judge motion state, eliminate potential safety hazard.
