Description

The soft bag vacuum arc suppressing transformer of a kind of striped with projection

Technical field

The utility model belongs to arc suppressing transformer technical field, is specifically related to the soft bag vacuum arc suppressing transformer of a kind of striped with projection.

Background technology

Prior art improves the method for epoxy resin and silicon rubber bonding force for pole, the process means generally taking the caking agent between epoxy resin and silicon rubber and silastic-layer outside surface to improve roughness ensures, but the process means that existing silastic-layer outside surface improves roughness exists following defect:

1. the soft pack layer of vacuum interrupter needs shaping and high temperature vulcanized formation, is eliminated the silicon rubber of surface cure after formation by the method for mechanical workout, and treatment process is loaded down with trivial details;

2. the uneven surface that the mechanical workout of vacuum interrupter soft pack layer plucking is formed, defines and compares surging electrostatic force, is difficult to remove at the dust of its surface adsorption, greasy dirt, paper scrap, rubber end;

3. although vacuum interrupter soft pack layer mechanical workout has uneven surface, but simple dependence uneven surface still is difficult to make epoxy resin and silicon rubber to combine closely;

4. the powder produced in the uneven surface mechanical processing process of vacuum interrupter soft pack layer plucking easily sucks the respiratory system of operator.

Practical novel content

The purpose of this utility model is to provide the soft bag vacuum arc suppressing transformer of a kind of striped with projection, the shortcoming poor in conjunction with effect of the dependence uneven surface that the soft bag surface solving existing vacuum interrupter exists and epoxy resin.

The technical scheme that the utility model adopts is: the soft bag vacuum arc suppressing transformer of a kind of striped with projection, comprising vacuum interrupter body and be wrapped in the silastic-layer of this external surface of vacuum interrupter, silastic-layer is provided with the striped of many projections on the surface.

Feature of the present utility model is also,

The both sides of the striped of every bar projection and the surperficial angle of silastic-layer are 40 °-50 °, and the head of the striped of projection is circular arc shape.

The striped of many projections is staggered mutually encloses webbed shape.

The striped of many projections surrounds multiple diamond shape.

The striped of silastic-layer and projection is formed in one formation.

The beneficial effects of the utility model are: the soft bag vacuum arc suppressing transformer of a kind of striped with projection of the present utility model solve the soft dependence uneven surface of bag surface existence and the shortcoming poor in conjunction with effect of epoxy resin of existing vacuum interrupter. The soft bag vacuum arc suppressing transformer of a kind of striped with projection of the present utility model have the following advantages:

The even structure on the soft pack layer surface 1, making vacuum interrupter corresponding with ceramic insulation shell, the bonding collection maintained between silicon rubber with epoxy resin is more evenly distributed, netted projection also add the bonding force of silastic-layer and epoxy resin, compare with plucking product, it is to increase pole withstand voltage ability and reliability;

2, the product originally needing two works step (soft bag and plucking) to complete shortening is completed by integrated silastic-layer and netted projection work step (soft bag), reduces energy consumption of unit product and shortens the process-cycle;

3, make uneven surface without the need to mechanical workout so that silastic-layer is band electrostatic force not, thus solve the easy attract dust of plucking product surface, greasy dirt, paper scrap, rubber end and be difficult to the shortcoming of removing;

4, owing to Product processing eliminates plucking work step, rubber end does not occur, stopped to adhere to the factor at rubber end, eliminate process facility and process time that product surface removes rubber end, reduce the manufacturing cost of product;

5, owing to having eliminated soft pack layer uneven surface mechanical processing tools, so that rubber powder no longer occurs in the course of processing, decrease the hazard factor of Occupational health or occupational illness, optimize production environment.

Embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.

The structure of the soft bag vacuum arc suppressing transformer of a kind of striped with projection that the utility model provides is as shown in Figure 1, comprising vacuum interrupter body 1 and be wrapped in the silastic-layer 2 of vacuum interrupter body 1 outside surface, silastic-layer 2 is provided with the striped 3 of many projections on the surface.

As shown in Figure 2, the both sides of the striped 3 of every bar projection and the surperficial angle of silastic-layer 2 are 40 °-50 °, and the head of the striped 3 of projection is circular arc shape.

The striped 3 of many projections is staggered mutually encloses webbed shape.

The striped 3 of many projections surrounds multiple diamond shape.

The striped 3 of silastic-layer 2 and projection is formed in one formation.

The silastic-layer 2 of soft bag vacuum arc suppressing transformer of a kind of striped with projection of the present utility model and the striped 3 of netted projection are formed in one and make, one-body molded process can be first make a soft bag fixture adapted with vacuum interrupter soft pack layer shape, internal surface at soft bag fixture is carved and is established the groove that striped 3 shape with netted projection adapts, then adopt after soft bag fixture parcel vacuum interrupter body 1 note process for filling colloid obtain the soft bag vacuum arc suppressing transformer of a kind of striped with projection of the present utility model. The soft pack layer making processes of the soft bag vacuum arc suppressing transformer of a kind of striped with projection of the present utility model is simple, striped 3 even structure of the projection on its surface, the bonding collection maintained between silicon rubber with epoxy resin is more evenly distributed, and the plucking step eliminated in conventional manufacture craft, reduce production cost, improve production efficiency, and not stuck foreign matter, avoid rubber powder to the injury of human body.
