Abstract
The utility model relates to a high -voltage switch field especially relates to high voltage circuit breaker's insulation system. Contain the insulator, it is protruding all to contain more than one on the inside and outside wall of insulator. Adopt as above technical scheme the utility model discloses, there is following beneficial effect for prior art: external shed and interior full skirt dual function for the insulating properties of holistic structure is better, has avoided internal discharge.
Description
Technical field
The utility model relates to high-voltage switch gear field, particularly relates to the insulation system of primary cut-out.
Background technology
At present, in the electric power system of 35KV electric pressure, the main outdoor breaker run and use has following several: vacuum circuit-breaker ZW7-40.5; The usage quantity of the bulk-oil circuit-breaker DW8-40.5. vacuum circuit-breaker of SF6 sulfur hexafluoride breaker LW8-40.5 and only a few accounts for the overwhelming majority.
In use, current ZW7-40.5 circuit breaker, build is large, highly reaches about 2500mm, transport and installation risk large; Frame adopts the welding of full-shape steel, and operation is loaded down with trivial details, makes trouble, and total man's work manufactures, and consistency is poor; Core operating mechanism adopts the CT19 mechanism of the eighties, and part is many, and fault is many, and structure closely, is difficult to maintenance.The connected driving parts such as insulated tension pole exposes among air, is subject to the impact of outside climatic, is easy to get rusty, and is easy to freeze to death, often can not action message.The transmission link of whole circuit breaker is more, and energy loss is serious, so require that the combined floodgate merit of mechanism is large, comparatively large to the impact of correlated parts, load is comparatively large, is difficult to mechanical endurance be up to state standards.Especially crucially insulation property are bad, affect fail safe.
Utility model content
The object of utility model: in order to provide a kind of insulation system of primary cut-out of better effects if, specific purposes are shown in multiple substantial technological effects of concrete implementation section.
In order to reach as above object, the utility model takes following technical scheme:
The insulation system of primary cut-out, comprises insulator, and the inside and outside wall of described insulator all comprises more than one projection.
The further technical scheme of the utility model is, also comprises the connecting rod that contact can be driven to contact at arc control device, connection rotating shaft below connecting rod, and rotating shaft connects brace, and brace side is fixed on the end of action axle, and action axle can stretch.
The further technical scheme of the utility model is, the projection on described inside and outside wall is respectively external shed and interior full skirt.
The further technical scheme of the utility model is, the diameter of described interior full skirt multiple skirt body structure is consistent.
The further technical scheme of the utility model is, it is silicon rubber umbrella skirt that described external shed and/or interior full skirt outside are coated with one deck silica gel.
The further technical scheme of the utility model is, described external shed and/or each own skirt body structure diameter of interior full skirt not necessarily consistent.
The further technical scheme of the utility model is, the skirt face of described external shed and/or interior full skirt is horizontal plane.
Adopt the utility model of as above technical scheme, have following beneficial effect relative to prior art: external shed and interior full skirt double action, make the insulation property of overall structure better, avoid internal discharge.
Accompanying drawing explanation
In order to further illustrate the utility model, be described further below in conjunction with accompanying drawing:
Fig. 1 is utility model structural representation; Wherein: 1. full skirt in; 2. external shed; 3. connecting rod; 4. rotating shaft; 5. brace; 6. action axle.
Embodiment
Be described embodiment of the present utility model below in conjunction with accompanying drawing, embodiment does not form restriction of the present utility model:
The insulation system of primary cut-out, comprises insulator, and the inside and outside wall of described insulator all comprises more than one projection.The technique effect of the essence that the technical scheme at this place plays and implementation procedure thereof are as follows: inside and outside wall all comprises more than one projection, all insulate inside and outside can realizing, make overall insulation effect better, effectively can increase creepage distance, after especially preventing condensation, cause electric discharge.
Also comprise the connecting rod that contact can be driven to contact at arc control device, connection rotating shaft below connecting rod, rotating shaft connects brace, and brace side is fixed on the end of action axle, and action axle can stretch.The technique effect of the essence that the technical scheme at this place plays and implementation procedure thereof are as follows: this place provides concrete manner of execution, can effectively realize cut-offfing of overall circuit breaker.
Projection on described inside and outside wall is respectively external shed and interior full skirt.
The diameter of described interior full skirt more than 1 skirt body structure is consistent.It is silicon rubber umbrella skirt that described external shed 2 and/or interior full skirt 1 outside are coated with one deck silica gel.The technique effect of the essence that the technical scheme at this place plays and implementation procedure thereof are as follows: adopt silicon rubber secondary package in the outside of entirety, increase creepage distance by increasing silicon rubber umbrella skirt.
Described external shed 2 and/or each own skirt body structure diameter of interior full skirt 1 not necessarily consistent.The technique effect of the essence that the technical scheme at this place plays and implementation procedure thereof are as follows: inconsistent structure, can not have the isolation material of the through entirety of possibility by rainwater, make the fail safe of structure and insulating properties better.
The skirt face of described external shed and/or interior full skirt is horizontal plane.The technique effect of the essence that the technical scheme at this place plays and implementation procedure thereof are as follows: due to the existence of horizontal plane, make flowing water directly can not form surfacewise through runner, also just avoid the electric discharge phenomena that water wire causes.
In a creative way, each effect above independently exists, and can also complete the combination of the above results with a nested structure.
It is clear that the technique effect that above structure realizes realizes, if do not consider the technical scheme of adding, this patent title can also be a kind of insulation system.Not shown part details.
It should be noted that, multiple schemes that this patent provides comprise basic scheme own, separate, mutually do not restrict, but it also can combine when not conflicting mutually, reaching multiple effect and jointly realizing.
More than show and describe general principle of the present utility model, principal character and advantage of the present utility model.Those skilled in the art should understand the utility model and not be restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed scope.
