By adopting technique scheme, when two clavate support insulators are interconnection, in utilization, the projection of joint flange snaps fit onto in the groove of lower joint flange, and the limited block group of upper joint flange snaps fit onto realize two joint flanges in the spacing groove group of lower joint flange circumferential spacing, finally by bolt limit shaft to radial direction, reduce due to two joint flanges circumferences not spacing time relatively rotate and improve the shear-stress of bolt, and then improve the work-ing life of insulator and connect fixing.
As preferably, described limited block group comprises at least one piece of the first limited block and one piece of the 2nd limited block, the width of described 2nd limited block is greater than the width of the first limited block;Described spacing groove group comprises the spacing groove of the spacing groove at least one place first and a place the 2nd, and described first limited block is connected in the first spacing groove, and the 2nd limited block is connected in the 2nd spacing groove.
By adopting technique scheme, the 2nd limited block distinguishes the first limited block, as a preset pieces and mark action so that can connect location two support insulators fast.
As preferably, described insulator also comprises gold utensil, lower gold utensil and connects the insulation plug of upper and lower gold utensil, described upper joint flange is located on the end face of gold utensil, lower joint flange is located on the end face of lower gold utensil, described insulation plug is outside equipped with multiple full skirt group, described full skirt group comprises the first full skirt setting up and down and the 2nd full skirt, and the diameter of described first full skirt is greater than the diameter of the 2nd full skirt.
By adopting technique scheme, the setting of full skirt group increases creepage distance, it is to increase breakdown characteristics.
As preferably, the circumference of described upper and lower gold utensil offers uniform bar-shaped trough, it is connected between two bar-shaped troughs to be formed strengthen block.
By adopting technique scheme, bar-shaped trough offer the quality first reducing two gold utensils, the reinforcement block secondly formed between two bar-shaped troughs ensure that the intensity of two gold utensils.
As preferably, described full skirt group is coated with silicon rubber.
By adopting technique scheme, improve the insulativity of insulator further.
Compared with prior art, the utility model has the advantage of: be connected in spacing groove group by limited block group and realize circumferential spacing to upper and lower joint flange, and utilize the 2nd limited block as mark positioning action Fast Installation two joint flange, it is to increase the rapidity installed.
