Abstract
The utility model discloses a directly operated type two-station isolation switch of solid insulation looped network cabinet. The cabinet comprises an insulating casing; a static contact at the front of the insulating casing and a middle static contact at the middle part of the insulating casing are arranged in the insulating casing; a movable contact coaxial with the static contact and the middle static contact and capable of moving back and forth in the insulating casing is also arranged in the insulating casing; the back and forth movement of the movable contact can make the static contact and the middle static contact be electrically connected or disconnected; a rear end of the movable contact is connected with an insulating pull rod; and an operation end of the insulating pull rod extends out of the insulating casing through a guide sleeve located at a rear end of the insulating casing. The above structure can change a rotation movement of a traditional isolation switch into linear motion, so as to make the movement more directly, save the space occupied by the movable contact; meanwhile, the motion state can be judged directly through the length of the insulating rod extending out of the insulating casing, thereby eliminating the safety hidden troubles.
Description
Technical field
The utility model relates to a kind of switch, specifically a kind of solid insulation ring main unit Direct Action Type two station disconnecting switchs.
Background technology
Isolating switch is to use maximum a kind of electrical equipment in the high-voltage switch electric appliance, the principles and structure of itself is fairly simple, but because use amount is large, functional reliability requires high, and existing isolating switch mostly is greatly knife switch, although can reach reliability requirement, but because that its structure arranges is unreasonable, on the one hand occupy the space larger, be difficult on the other hand judge the residing state of switch, bring many inconvenience to people thus, also had numerous potential safety hazards simultaneously.
Summary of the invention
The technical problems to be solved in the utility model provide a kind of simple in structure, use reliable and solid insulation ring main unit Direct Action Type two station disconnecting switchs of display working condition directly perceived.
In order to solve the problems of the technologies described above, solid insulation ring main unit Direct Action Type two station disconnecting switchs of the present utility model, comprise insulation shell, be provided with fixed contact and a middle fixed contact that is positioned at the insulation shell mid portion that is positioned at the insulation shell front end in the insulation shell, also has a moving contact that also can in insulation shell, move forward and backward with fixed contact and the coaxial setting of middle contact in the insulation shell, the moving forward and backward of moving contact can make fixed 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 insulation shell by the guide pin bushing that is positioned at the insulation shell rear end.
Described insulated tension pole is provided with one section bellows near an end of moving contact.
Be respectively arranged with spring touch finger in described fixed contact and the middle fixed contact.
After adopting above-mentioned structure, owing to being provided with fixed contact and middle contact in the insulation shell, also be provided with one with fixed contact and the coaxial setting of middle fixed contact and the moving contact that can in insulation shell, move forward and backward, arrange thus and can change rotatablely moving of traditional isolating switch into rectilinear motion, make thus its motion more direct, save the shared space of moving contact action, also can stretch out the outer length of insulation shell by insulated tension pole simultaneously and directly judge motion state, eliminated potential safety hazard.
