Description
Technical field
The utility model relates to sleeve pipe, relates in particular to a kind of High Voltage Outdoor sleeve pipe.
Background technology
In wind power transformation depressor, be mainly at present to adopt sleeve pipe to do the connection inside and outside transformer, he mainly comprises core body and silicon rubber full skirt, described core body comprises conducting rod and is arranged on the pour mass of conducting rod outside, the outer surface of described pour mass is provided with flange, described silicon rubber full skirt is wrapped in the position that pour mass upper flange is kept right, the position that described pour mass upper flange keeps left is stretched in oil by transformer box wall perforate, is fixed, and be equipped with sealing ring and prevent leakage of oil by flange screw.
But the sleeve pipe of prior art is owing to using outside, so environment for use is more severe, and be the high-tension electricity of 35kv electric pressure because of what transmit on sleeve pipe again, and flange is connected with ground, therefore make the non-uniform electric of flange, the serious flashover phenomenon of normal appearance in industrial frequency withstand voltage test or actual use, thus impact is used safety greatly; The conducting rod of prior art sleeve pipe is directly fixing with pour mass, and conducting rod can be because heating be expanded after transferring high voltage electricity, and then affects the combination of conducting rod and pour mass, causes sleeve pipe to move unreliable; And the sleeve pipe of prior art is because conducting rod is wrapped in pour mass, so be not easy to detect whether conducting rod switches on.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of security performance good, reliable and can detect the High Voltage Outdoor sleeve pipe whether its inner conductive bar switches on.
The technical scheme that the utility model adopts is: a kind of High Voltage Outdoor sleeve pipe, comprise core body and silicon rubber full skirt, described core body comprises conducting rod and is arranged on the pour mass of conducting rod outside, the outer surface of described pour mass is provided with flange, described silicon rubber full skirt is wrapped in the position on pour mass upper flange and flange right side, the position in described pour mass upper flange left side is stretched in oil and by flange screw and is fixed by transformer box wall perforate, in pour mass between described flange and conducting rod, be provided with one for preventing the metal net mask of flashover phenomenon generation, described flange is provided with two symmetrical screws, and described screw is all electrically connected with metal net mask by wire, between described conducting rod and pour mass, be also provided with one deck resilient coating.
Adopt above structure compared with prior art, the utlity model has following advantage: a metal net mask is set in the pour mass between flange and conducting rod, can effectively solve like this problem that flange non-uniform electric arrives, avoid the flashover phenomenon occurring in industrial frequency withstand voltage test or actual use, thereby made whole casing safety performance higher; And a resilient coating is set between conducting rod and pour mass, and conducting rod energising can not affect after expanding and the combination of pour mass like this, and then makes operational reliability higher; Again because be provided with screw at flange, and described screw is electrically connected with metal net mask by wire, because metal net mask can sense in conducting rod whether switch on, connect on electrification display of direct connection at screw place so again, so just can detect whether conducting rod has been with a little.
As preferably, described silicon rubber full skirt comprises multiple large full skirts and little full skirt, and described large full skirt and little full skirt are arranged alternately.Arrange like this and can meet the requirement of sleeve pipe to various environment and the class of insulation.
As preferably, the side of described flange is provided with the annular groove of accommodating sealing ring.The casing flange that the application is set like this can effectively avoid sealing ring to expose, make sealing effectiveness better.
