Description

Flange form filling transformer insulator
Technical field
The utility model relates to High-Voltage Electrical Appliances field of components, particularly a kind of flange form filling transformer insulator.
Background technology
Porcelain shell for transformer is the primary insulation device outside transformer tank, and the lead-out wire of Transformer Winding has to pass through insulated porcelain sleeve, makes to insulate between lead-out wire and between lead-out wire and transformer case, plays fixing lead-out wire simultaneously.Because electric pressure is different, insulated porcelain sleeve has the forms such as true procelain cover, oil-filled insulator and electric capacity insulator.Oil-filled insulator is multiplex, and at 35kV level transformer, it is oil-filled at insulator, and in insulator, wear a conducting rod, conducting rod is provided with binding post.At present, the flange form filling transformer insulator of prior art has following point: conducting rod and gap between insulator larger, cannot realize good location between conducting rod and insulator, conducting rod can produce rotation, the unbalance stress of hermetically-sealed construction can be caused, thus affect the sealing of product.
Summary of the invention
Technical problem to be solved in the utility model is: provide that circumferential limit effect between a kind of conducting rod and insulator is better, product sealing effectiveness better flange form filling transformer insulator.
The technical scheme in the invention for solving the above technical problem is: a kind of flange form filling transformer insulator, comprise sleeve pipe, the conducting rod of inner chamber that fit is installed on sleeve pipe and the binding post that is fixed on conducting rod, the top of described conducting rod is fixedly connected on insulator upper end by least one nut; Described conducting rod is provided with position limiting convex ring, and described insulator inner chamber is provided with limited step, is provided with cushion pad between described position limiting convex ring and described limited step; The top of described limited step is provided with at least one location notch, and described conducting rod periphery is provided with and realizes the spacing alignment pin of circumference for matching with described location notch.
Compared with prior art, the utility model has the advantage of: the conducting rod of this flange form filling transformer insulator is provided with position limiting convex ring, and insulator inner chamber is provided with limited step, is provided with cushion pad between position limiting convex ring and limited step; The top of limited step is provided with at least one location notch, and conducting rod periphery is provided with and realizes the spacing alignment pin of circumference for matching with location notch.Like this, be provided with cushion pad between position limiting convex ring and limited step, axial limiting can be realized well, good location can be realized by alignment pin and arranging between conducting rod and insulator inner chamber of location notch, conducting rod not easily produces and rotates in a circumferential direction, and better can ensure the sealing effectiveness of product.
As preferably, the bottom fit of described sleeve pipe is provided with flange, and is provided with silastic-layer between described flange and described sleeve pipe periphery.Like this, flange is more convenient by the fixed installation of silastic-layer.
As preferably, the inner surface of described flange is provided with the jog matched with described silastic-layer of multiple continuous setting, and the bottom of described sleeve pipe is provided with the one wave part for matching with described silastic-layer.Like this, the fixed effect between silastic-layer and flange and sleeve pipe is better.
As preferably, between described nut and conducting rod, be provided with the sealant beads for sealing.Like this, sealing effectiveness is better.
As preferably, the bottom of described nut is also provided with trim ring, and is provided with sealing gasket before described trim ring and described sleeve upper end face.Like this, sealing effectiveness is better.
