Abstract
The utility model relates to a post insulator, which comprises an insulator, a cast iron seat and cement stuffing arranged between the insulator and the cast iron seat, wherein the insulator comprises an insulator body and an insulator boss arranged at the lower end of the insulator body. In the utility model, the stress state of the joint of the post insulator and the cast iron seat is improved by changing the joint part of the insulator so as to prevent the insulator from cracking because the cast iron is tightened, and thereby, the service life of the insulator is prolonged.
Description
Technical field
The utility model relates to a kind of post insulator.
Background technology
The column support type insulator is used in usually in the disconnecting link switch and supports transmission pressure.When the weather cataclysm, crackle can take place in the root of post insulator, and the crackle expansion causes the fracture of column support type insulator to fall.Analyzing one of crack reason is that coefficient of expansion cast iron is relatively large because the thermal coefficient of expansion of pottery is little, and when temperature decrease, the cast iron seat forms excessive inflexible tight power to ceramic insulator, thereby forms crackle; Former two is because insulator use cemented in the cast iron seat therefore, and cement is met water the phenomenon that rises that wets can occur, and then ceramic insulator is formed the appearance that excessive inflexible tight power causes crackle.
The utility model content
Technical problem to be solved in the utility model provides a kind of insulator that prevents and crackle occurs, effectively prolongs the insulator post insulator in useful life.
The utility model adopts following technical scheme:
The utility model comprise insulator, cast iron seat and be arranged on insulator and the cast iron seat between the cement inserts, described insulator is made of insulation daughter and the insulator boss that is arranged on insulation daughter lower end.
Insulation daughter described in the utility model and surface, insulator boss junction are arc chord angle.
The beneficial effects of the utility model: thus the utility model is to improve column support type insulator and cast iron seat joint stress state by the profile that changes the insulator junction, avoid forming the cast iron seat and arrest tight and make insulator crackle occur, prolong the useful life of insulator.
Description of drawings
Accompanying drawing 1 is the utility model structural representation;
Accompanying drawing 2 is the utility model plan structure schematic diagram.
In the accompanying drawings: 1 insulator, 2 cement inserts, 3 cast iron seats, 4 insulator boss, 5 arc chord angles.
Embodiment
Shown in accompanying drawing 1,2, the utility model comprise insulator 1, cast iron seat 3 and be arranged on insulator 1 and cast iron seat 3 between cement inserts 2, described insulator 1 is made of insulation daughter and the insulator boss 4 that is arranged on insulation daughter lower end, and described insulation daughter and surface, insulator boss 4 junctions are arc chord angle 5.The utility model insulator 1 root strengthens, insulator boss 4 promptly is set, insulator boss 4 adopts arc chord angle 5 transition with top insulation daughter, when cast iron seat 3 shrinks, shrinkage stress disperses by the core of arc chord angle 5 to insulator 1, can avoid cast iron seat 3, cement inserts 2 to concentrate, avoid occurring crackle with the stress of insulator 1 bonding station.The position, arc chord angle 5 lower edge of the utility model insulator boss 4 should be a little less than cast iron seat 3 or concordant with it.
Claims (2)
