Abstract
The utility model provided an insulation pull bar structure, which comprises an upper end joint, an insulation pull bar and a lower end joint which are connected in sequence; and a plug at the upper end joint is plugged in a left end of the insulation pull bar and bonded, a plug at the lower end joint is plugged in a right end of the insulation pull bar and bonded, and a shielding separator plate is arranged between a handle part and the plug of the upper end joint. The beneficial effects are that: an original upper end joint and a shielding cover are designed into one connector, problems that an original is not firm in compression joint, processing difficulty is great and cost is high are solved, impact resistance of the insulation pull bar is increased, and a sliding friction force is reduced when an arc extinguish chamber is open and closed; an electric field is improved, cost is saved and security when the arc extinguish chamber is open and closed is improved; and a phenomenon that the shielding cover falls off to cause a power failure accident when the breaker arc extinguish chamber is open and closed is prevented.
Description
Technical field
The utility model belongs to high-voltage switch circuit breaker arc control device and operating mechanism, relates to a kind of insulated tension pole structure.
Background technology
Present stage, the GIS arc-extinguishing chamber of circuit breaker of 126kV and following electric pressure and operating mechanism are connected to insulated tension pole and radome crimping structure.This project organization difficulty of processing is large, contact-making surface crimping discontinuity, in the situation that do not have buffering area easily occur radome obscission, processing and manufacturing cost expensive, to providing arc-extinguishing chamber of circuit breaker deciliter operability poor, easily having an accident during short-circuit current rush.
Summary of the invention
The utility model provides in order to make up the deficiencies in the prior art the insulated tension pole structure that a kind of cost is low, simple and reliable for structure, be convenient to assemble.
The utility model is achieved by the following technical solution:
Insulated tension pole structure of the present utility model, its special character is: comprise the upper end connector, insulated tension pole and the lower end connector that connect successively, it is inner and bonding that the plug of upper end connector inserts the insulated tension pole left end, it is inner and bonding that the plug of lower end connector inserts the insulated tension pole right-hand member, is provided with shielded partitions between the shank of upper end connector and plug.
The beneficial effects of the utility model are, original upper end connector and radome are designed to a joint form, the insecure problem of original coupling compression joint and the high problem of the large expense of difficulty of processing have been solved, the impact resistance of reinforced insulation pull bar, the force of sliding friction when having reduced arc control device deciliter; Improved electric field, saved cost, the fail safe when having improved arc control device deciliter.This design is mainly used in the GIS(Cubicle Gas-Insulated Switchgear of 126kV and following electric pressure).Avoid radome to come off when arc-extinguishing chamber of circuit breaker deciliter and cause the phenomenon of power outage.
Description of drawings
Fig. 1 is that tradition embeds the insulated tension pole sectional arrangement drawing, and Fig. 2 is the outline drawing of Fig. 1.Fig. 3 is the utility model insulated tension pole assembling cutaway view, and Fig. 4 is the outline drawing of Fig. 3.
In figure: end connector on 1,2 insulated tension poles, 3 times end connectors, 4 epoxy bond places, 5 shielded partitions, 6 radomes.
Embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.
Insulated tension pole structure of the present utility model, comprise the upper end connector 1, insulated tension pole 2 and the lower end connector 3 that connect successively, it is inner and bonding that the plug of upper end connector 1 inserts insulated tension pole 2 left ends, it is inner and bonding that the plug of lower end connector 3 inserts insulated tension pole 2 right-hand members, is provided with shielded partitions 5 between the shank of upper end connector 1 and plug.
Insulated tension pole structure of the present utility model, namely 126kVGIS with New insulated pull bar bonded structure, belongs to high-voltage switch gear inner with a kind of new structure of insulated tension pole.Mainly comprise end connector, insulated tension pole, lower end connector, it is inner and bonding by the 0.1kg epoxy adhesive that the plug of upper end connector 1 inserts insulated tension pole 2 left ends, formation epoxy bond place 4, it is inner and bonding by the 0.1kg epoxy adhesive that the plug of lower end connector 1 inserts insulated tension pole 2 right-hand members, forms the epoxy bond place.In this structure, original upper end connector and radome are designed to a joint form, have solved the insecure problem of original coupling compression joint and the high problem of the large expense of difficulty of processing, the impact resistance of reinforced insulation pull bar, the force of sliding friction when having reduced arc control device deciliter; Improved electric field, saved cost, the fail safe when having improved arc control device deciliter.This design is mainly used in the GIS(Cubicle Gas-Insulated Switchgear of 126kV and following electric pressure).Avoid radome to come off when arc-extinguishing chamber of circuit breaker deciliter and cause the phenomenon of power outage.
