The insulating cylinder is simple in structure, easy for operation and manufacture, and high in stability.
Description
Technical field
The utility model is a kind of insulating cylinder, particularly a kind of insulating cylinder device that is used for power transformer enclosure.
Background technology
Insulating cylinder complex structure of the prior art, and the production cycle is long, and the production cost height is made complexity relatively, makes high voltage bushing bottom voltage equalizing ball to seat wall and the wall square corner burr generation disruptive discharge phenomenon of raising easily.
Chinese patent CN2598304 discloses a kind of insulating cylinder, and it comprises cylindrical shell, cover, and the openend outside of cylindrical shell has two wedge shape boss at least, with wedge shape boss corresponding position annular notches is arranged on the cover, and the wedge shape boss just in time is stuck in the annular notches.This utility model complex structure is made complicated.
Summary of the invention
Utility model mainly is to solve the deficiencies in the prior art, and a kind of insulating cylinder device that is used for power transformer enclosure is provided.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of insulating cylinder device that is used for power transformer enclosure, comprise pedestal, described pedestal is provided with the seat that raises, be provided with insulating cylinder in the described rising seat, described insulating cylinder comprises insulating cylinder I, insulating cylinder II and insulating cylinder III, described insulating cylinder II is socketed in the insulating cylinder I, described insulating cylinder III is socketed in the insulating cylinder I and pastes on the insulating cylinder I, be provided with the sleeve pipe voltage equalizing ball in the described insulating cylinder, described sleeve pipe voltage equalizing ball is connected with lead-in wire, and described insulating cylinder I, insulating cylinder II and insulating cylinder III are complementary.The insulating cylinder III is pasted on the insulating cylinder I, insulating cylinder II and insulating cylinder I leave the gap, guarantee that the insulating cylinder II can arbitrarily move, main working voltage grade 220kv and voltage equalizing ball place, above sleeve pipe bottom, when this structure is convenient to observe cooperating of sleeve pipe voltage equalizing ball and lead-in wire, effectively prevented the disruptive discharge phenomenon of bushing bottom voltage equalizing ball to raise seat wall and wall square corner burr.
As preferably, the sidewall of described insulating cylinder II is provided with the button breach that concaves, and the sidewall of described insulating cylinder III is provided with the button mouth of stretching to the upper edge, and described button mouth and button breach are complementary.
As preferably, be provided with two layers in the described rising seat and support ring layers, described support ring layer is positioned at the top and bottom of the seat that raises, and supports ring layer and insulating cylinder by securing member close-fitting mutually.
As preferably, the cross section shape of described support ring layer is " L " shape, and an end that supports ring layer fixes with the inwall of the seat that raises, and supports the other end of ring layer and the outer wall of insulating cylinder and fixes.
Therefore, the insulating cylinder device that is used for power transformer enclosure that the utility model provides, simple in structure, easy to operate, make simple, stable high.
