Abstract
A hermetically sealed construction for a suspended insulator arrester comprises an insulated canister covered with an outer compound insulating casing, an insulator mandrel arranged in the center of the insulated canister and a bulb. A flange is arranged on the head of the insulated canister; a seal ring is arranged between the flange and the end face of the insulated canister; the bulb is pressed and connected on the insulator mandrel; a seal ring is arranged between the outer side face of the bulb and the inner wall of the flange. The hermetically sealed construction not only ensures the seal performance, but also improves the intensity to resist tension load, and is processed and assembled conveniently.
Description
Technical field
The utility model relates to a kind of suspended isolator lightning arrester hermetically-sealed construction, mainly is the sealing problem that solves insulating cylinder.
Background technology
The suspended isolator lightning arrester has insulator and lightning arrester dual-use function because of it, begins to use in batches at power transmission and transformation system.Though and existing suspended isolator lightning arrester has higher mechanical strength, good tensile load performance, because flange and bulb partly are the monoblock cast structures, insulating cylinder and insulating rod are subjected to pulling force simultaneously in actual the use.Bulb is crimped on the insulating glass rod, and the stretch-proof load intensity is very up to more than the 10t.And the stretcher strain elongation reaches 1% more greatly, and insulating cylinder and flange are that the stretch-proof load intensity that is threaded is not high.Because of glass insulation tube and glass insulation rod stretcher strain amount or stretch-proof load-bearing capacity are different, product in use or insulating glass tube threaded portion is damaged when adding tensile load, the sealing property forfeiture, accident appears in lightning arrester.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of suspended isolator lightning arrester hermetically-sealed construction at above-mentioned prior art present situation, has both guaranteed sealing property by this structure, improves the stretch-proof load intensity, is convenient to processing, assembling again.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this suspended isolator lightning arrester hermetically-sealed construction, comprise that external packets is covered with the insulating cylinder of composite insulation outer coat, place the insulation mandrel at insulating cylinder center, and bulb, wherein the head of insulating cylinder is equipped with flange, between the end face of flange and insulating cylinder sealing ring is housed, its feature is provided with sealing ring being that described bulb is crimped on the insulation mandrel between the lateral surface of bulb and the flange inner wall.
Compared with prior art, advantage of the present utility model is: because bulb and insulation mandrel are crimped on together, be provided with sealing ring between bulb side and the insulating cylinder, thereby insulation mandrel extends when being subjected to tensile load, bulb moves outward but because the protection of side seal circle is arranged, can not influence sealing property; Because bulb and flange separate, can not have influence on the insulating cylinder insulating cylinder during stretching and not bear pulling force simultaneously, more can not cause sealing property failure or insulating cylinder to damage certainly; Also need not be again during check the elongation of strict control insulation mandrel, thereby by this structure can accomplish to assemble more convenient, sealing property is more excellent, the stretch-proof load performance is higher.
