Abstract
The invention relates to an insulator, in particular to a hollow insulator for a column type circuit breaker, which is capable of resisting hydrofluoric acid corrosion. The hollow insulator comprises a cylindrical pipe, a parachute cluster and flanges. The parachute cluster is wrapped on the outer layer of the cylindrical pip; the flanges are sleeved at both ends of the cylindrical pipe; a polytetrafluoroethylene liner is installed in the cylindrical pipe; and a corrosion resistance coating is filled at the joint of the flanges and the end surface of the cylindrical pipe. By adopting the structure, the insulator is avoided being corroded by hydrofluoric acid gas generated by electrical arcs, and the service life of the insulator is prolonged.
Description
Technical field
The present invention relates to a kind of insulator, particularly a kind of hollow insulator that is used for column type circuit breaker.
Background technology
Column type circuit breaker tends to produce higher cut-off overvoltage and electric arc when cut-offfing, and discharges hydrofluoric acid gas, and the corrosion insulator reduces its useful life.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of hollow insulator for column type circuit breaker of hydrofluoric acid corrosion resistance.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of hollow insulator for column type circuit breaker, comprise cylindrical tube, cluster parachute and flange, the cylindrical tube skin is coated with cluster parachute, two ends in described cylindrical tube are with flange, and its innovative point is: in described cylindrical tube polytetrafluoroethyllining lining is housed; The end face junction of described flange and cylindrical tube is filled with corrosion-resistant finishes.
The advantage of invention is: the end face junction that polytetrafluoroethyllining lining and described flange and cylindrical tube are housed in the insulator cylindrical tube is filled with the corrosion resistance that corrosion-resistant finishes improves insulator, improves its useful life.
Description of drawings
Fig. 1 is a hollow insulator for column type circuit breaker structural representation of the present invention;
Fig. 2 is the partial schematic diagram of hollow insulator for column type circuit breaker of the present invention.
Embodiment
