Description

A kind of suspension insulator

Technical field

The utility model relates to field of electrical equipment, particularly a kind of suspension insulator.

Background technology

Insulator is widely used in power equipment, generally belongs to exterior insulation, and the external belt electric conductor of the bus of overhead transmission line, power plant and electric substation and various electric equipments must be supported with insulator.

Suspension insulator is the insulator of a kind of comparatively extensive use in insulator, is generally by porcelain piece and makes.Existing suspended porcelain insulator is generally comprised of suspension insulator porcelain piece, steel cap and steel pin.Steel cap, on suspended porcelain insulator porcelain piece, and is installed together by steel pin, and steel pin is through the bottom of suspension insulator porcelain piece and steel cap.

But inventor finds in realizing process of the present utility model:

In the process of mucilage binding suspension insulator, in order to prevent the expanding with heat and contract with cold for the impact of suspension insulator of mucilage binding agent, when producing suspension insulator, need between suspension insulator porcelain piece and steel cap, guarantee certain space, to guarantee that suspension insulator can not injured because expanding with heat and contract with cold.In order to guarantee this space, cause current production method very complicated, require great effort time-consuming.

Utility model content

In order to address the above problem, the utility model embodiment provides a kind of suspension insulator.Described technical scheme is as follows:

A suspension insulator, described suspension insulator comprises:

Suspension insulator porcelain piece (1), steel cap (2), steel pin (3) and isolation rubber pad (4);

Wherein, described steel cap (2) is installed on described suspension insulator porcelain piece (1) top by described steel pin (3), described isolation rubber pad (4), between suspension insulator porcelain piece (1) and described steel cap (2), and is passed by described steel pin (3).

Further, described isolation rubber pad (4) is circular.

Further, described isolation rubber pad (4) is colloid and has elasticity.

The beneficial effect that the technical scheme that the utility model embodiment provides is brought is: by install isolation rubber pad additional between suspension insulator porcelain piece and steel cap, can when producing, not need to guarantee gap, both can guarantee that suspension insulator was not injured by expanding with heat and contract with cold, during production, can laborsavingly save time again, alleviate manual labor, increase work efficiency, meanwhile, rubber cushion can promote the anti-radio interference function of suspension insulator.

Accompanying drawing explanation

In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.

Fig. 1 is the structural representation of the suspension insulator that provides in the utility model embodiment.

In above each figure, the meaning of label is as follows:

1 suspension insulator porcelain piece; 2 steel caps; 3 steel pin; 4 isolation rubber pads.

Embodiment

For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, the utility model execution mode is described in further detail.

As shown in Figure 1, the utility model embodiment provides a kind of suspension insulator, and this suspension insulator comprises:

Suspension insulator porcelain piece (1), steel cap (2), steel pin (3) and isolation rubber pad (4);

Wherein, steel cap (2) is installed on suspension insulator porcelain piece (1) top by steel pin (3), and isolation rubber pad (4), between suspension insulator porcelain piece (1) and steel cap (2), and is passed by steel pin (3).

Further, isolation rubber pad (4) is circular.

Further, isolation rubber pad (4) is colloid and has elasticity.

Wherein, the height of suspension insulator is as shown in Figure 1 146mm, and maximum gauge is 255mm.It should be noted that, the data in Fig. 1 are only used to exemplary illustration, can not limit the specification of suspension insulator.

In suspension insulator porcelain piece (1) in the suspension insulator that the utility model provides and the dilatation joint of steel cap (2), install isolation rubber pad (4) additional; be specially circular, soft, whippy isolation rubber pad; when producing; when theing cement solidifies; isolation rubber pad (4) need not divest (because of the soft high resilience of rubber cushion, equally can play protection product at the Shi Buhui that expands with heat and contract with cold, come to harm); directly into water curing; saved the loaded down with trivial details operation that rubber cushion divests; between product porcelain piece and steel cap, there is one deck insulation rubber cushion to be separated by simultaneously, can improve again the performance of anti-radio interference.

In order to adapt to more product, the specification of isolation rubber pad (4) can be:

Thickness 1.9 ± 0.1mm, external diameter 88 ± 0.5 internal diameters 78 ± 0.5, external diameter 95 ± 0.5mm, the plurality of specifications such as internal diameter 86 ± 0.5mm.

When implementing, due to isolation rubber pad, need to there is the performance requirements such as matter is soft, high resilience, the present embodiment also provides its manufacture method, specific as follows:

To be arranged on vulcanizing press for making the mould of isolation rubber pad (4);

Use the preheat temperature of vulcanizing press to be set to the first preset temperature;

When reaching the first preset temperature, methyl vinyl silicone rubber is dosed in mould;

Mould is closed up, and boost to 15 MPas and carry out vulcanisation operation;

Vulcanisation operation was carried out after 15 minutes, opened the finished product that mould obtains isolation rubber pad (4).

Further, the first preset temperature is higher than 140 ℃, lower than 160 ℃.

Further, by for making before the mould of isolation rubber pad (4) is arranged on vulcanizing press, method also comprises:

According to the specification of isolation rubber pad (4), make corresponding mould.

It should be noted that when making, also need to control the quality of isolation rubber pad finished product, product is smooth, flexible, it is qualified without burr, lump etc., to be.

By said method, make the isolation rubber pad matter obtain soft, insulate, have elasticity, meet the performance requirement of the required isolation rubber pad of suspension insulator in the utility model.

The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection range of the present utility model.
