Description
Technical field
The utility model relates to a kind of device for switching, particularly high voltage isolator.
Background technology
At present, the structure of the revoling tube assembly of domestic rotating type high-pressure isolating switch is directly electric conductor to be penetrated porcelain insulating sleeve pipe or epoxy resins insulation sleeve pipe basically, the product that the big electric current of part also arranged is infusion epoxy resin between electric conductor and porcelain insulating sleeve pipe also, relies on the insulation between insulating sleeve realization center conductor and framework and the adjacent center conductor.Owing between center conductor and porcelain insulating sleeve pipe or the epoxy resins insulation sleeve pipe air is arranged, even infusion epoxy resin also exist thermal expansion, air do not drain, bonding not firm, non-uniform electric, rely on outside porcelain or epoxy resins insulation cover pipe insulation fully, because spatial volume restriction, the insulation safety nargin of porcelain or epoxy resins insulation sleeve pipe is not enough, causes electric accident easily.
Summary of the invention
The purpose of this utility model is to provide a kind of rotating type high-pressure isolating switch, has insulation safety nargin height, high low temperature adaptability is strong, has solved not enough, the easy shortcoming of discharge breakdown of traditional product insulation safety nargin.
The purpose of this utility model realizes by following scheme: a kind of rotating type high-pressure isolating switch, comprise framework, framework each side is provided with one group of post insulator, the setting that is centrosymmetric of the post insulator of the described framework left and right sides, post insulator is provided with contact, be elasticly connected with the copper fingertip on the contact, the horizontal center of described framework is provided with rotating shaft, be connected with and post insulator revoling tube assembly one to one through strutting piece in the rotating shaft, described revoling tube assembly comprises center conductor, interior insulating sleeve, external insulation casing pipe and end cap, insulating sleeve is sleeved on outside the center conductor in described, outside the insulating sleeve, described end cap was arranged on the external insulation casing pipe two ends in external insulation casing pipe was sleeved on; During combined floodgate, the center conductor two ends just simultaneously contact with copper fingertip on the post insulator of the framework left and right sides.
The utility model is insulating sleeve in the outer setting of center conductor, and interior insulating sleeve can be pyrocondensation insulating sleeve or shrinkage insulating sleeve; External insulation casing pipe is set again, and external insulation casing pipe can be magnetic insulation sleeve pipe or epoxy resins insulation sleeve pipe, and its good insulating can adopt the fastening or threaded engagement of screw between end cap and the center conductor; The beneficial effect of this device is: the revoling tube assembly has the good insulation performance performance, and certain elasticity is arranged, and has both strengthened insulation property greatly, has solved the problem of thermal expansion simultaneously; Owing to adopted technique scheme, rotating type high-pressure isolating switch of the present utility model to have insulation safety nargin height, the adaptable characteristics of high low temperature.
For guaranteeing that separating brake reliably reaches the static that discharges the revoling tube assembly, described framework is provided with and the corresponding fixed card of revoling tube assembly, and during separating brake, center conductor one end of revoling tube assembly snaps in the fixed card just.
Described center conductor can be the electric conductor of tubulose, bar-shaped or strip.
