To achieve these goals, the utility model solves the technical scheme that its technical problem adopts: transformer compression joint type sleeve pipe, comprise conductive pole, explosion-proof insulator, clamping cover for seat, first sealing clamping ring, second sealing clamping ring, pad, clamp nut, one end of described conductive pole is provided with axial limiting seat and connector lug, the main body of the conductive pole of the other end of conductive pole offers connecting thread, described first sealing clamping ring, explosion-proof insulator, second sealing clamping ring, clamping cover for seat successively encapsulation on conductive pole, and by pad and clamp nut locking, described axial limiting seat is provided with the annular groove of accommodation first sealing clamping ring, the degree of depth of described annular groove is less than the thickness of the first sealing clamping ring, the lower surface of described explosion-proof insulator offers recessed anchor ring, be positioned at recessed anchor ring and explosion-proof insulator upper surface all offers annular groove.
The transformer compression joint type sleeve pipe that the utility model provides further, the degree of depth of its annular groove is at least 1/3 of the first sealing clamping ring thickness;
The transformer compression joint type sleeve pipe that the utility model provides further, the socket through-hole wall that the middle part of its explosion-proof insulator 3 is offered is provided with ring-shaped step, and ring-shaped step is positioned at the upper end of explosion-proof insulator 3.
The transformer compression joint type sleeve pipe that the utility model provides further, its inside and outside trough rim diameter being positioned at the annular groove that recessed anchor ring is offered all is less than the outer annular edge diameter of the second sealing clamping ring and is greater than the inner ring limit diameter of the second sealing clamping ring;
The transformer compression joint type sleeve pipe that the utility model provides further, its inside and outside trough rim diameter being positioned at the annular groove that explosion-proof insulator 3 upper surface is offered all is less than the outer annular edge diameter of the first sealing clamping ring 2 and is greater than the inner ring limit diameter of the first sealing clamping ring.
The transformer compression joint type sleeve pipe that the utility model provides further, the width of its annular groove is 1 to 3 millimeter; Its degree of depth is 0.5 to 2 millimeter.
The beneficial effects of the utility model: the sealing structure of this transformer compression joint type sleeve pipe is good, there will not be because respective outer side edges crimps the defect closely not occurring seepage space within the seal durability time limit, even if aging the breaking of seal comes off, partial seal in embedded rings connected in star can not depart from and continues to play sealing function, ensures the stable of transformer useful life and performance to greatest extent.
