Abstract

The utility model relates to the field of manufacture and design of high voltage switches and discloses a flow guide shield used for a composite apparatus arc extinguish chamber. The flow guide shield comprises an insulation support, an outer flow guide shield, an inner flow guide shield, a contact base and a shielding case which are arranged coaxially, and further comprises an arcing contact and a contact piece which are located on the contact base and in the shielding case. The outer flow guide shield is fixed on the insulation support. The inner flow guide shield is disposed in the outer flow guide shield. A part of the contact base extends into the outer flow guide shield to be contacted with the inner flow guide shield. The shielding case is disposed at the end, which is opposite to the inner flow guide shield, of the contact base. The flow guide shield can diffuse high temperature free gas generated by arc to the inside of the outer flow guide shield rapidly and thus increases the recovery speed of insulation in breaks, and meanwhile guarantees the dielectric strength in main breaks. With the flow guide shield, the size of the shell of a breaker of a composite apparatus can be reduced and the objective of miniaturization can be achieved.

Description

A kind of kuppe for combined electrical apparatus arc control device
[technical field]
The utility model relates to high-voltage switch gear manufacturing and design field, particularly a kind of kuppe for combined electrical apparatus arc control device.Be applicable to each electric pressure, be specially adapted to the product of the frame grounds such as GIS combined electrical apparatus, potting breaker and the compound electric apparatus in high-voltage switch gear field, effectively reduce shell dimension, reach the object of miniaturization.
[background technology]
Realizing product miniaturization, further reduce operating work, improve reliability and the economy of product, is the emphasis of power equipment development.Guaranteeing that under the constant prerequisite of integral insulation level, overall through-current capability, circuit breaker break performance, dwindling of arc-extinguishing chamber of circuit breaker shell dimension, will reduce the integrated spaced size of combined electrical apparatus, reduces Financial cost, improves the competitiveness of product in market.
[utility model content]
The purpose of this utility model is to design a kind of kuppe for combined electrical apparatus arc control device.The application of the utility model kuppe can reduce the size of Shell of circuit breaker in combined electrical apparatus, reaches the object of miniaturization.
In order to achieve the above object, the utility model is achieved by the following technical solutions.
A kind of kuppe for combined electrical apparatus arc control device, comprise the insulation column of coaxial setting, outer kuppe, interior kuppe, contact base, radome, and be arranged on contact base and be positioned at arcing contact and the contact of radome, described outer kuppe is fixed on insulation column, described interior kuppe is arranged on outer kuppe inside, described contact base part stretches in outer kuppe and contacts with interior kuppe, and it is the end relative with interior kuppe that described radome is arranged on contact base; Interior kuppe centre position has radial ruler modest ability, the first short rectangle pod apertures of lateral dimension, have the second rectangle pod apertures short with the radial dimension of this first rectangle pod apertures relevant position, that lateral dimension is long at the apical position of interior kuppe, the high temperature free gas that electric arc causes diffuses to outer kuppe from the first rectangle pod apertures and the second rectangle pod apertures.
The part of described contact base is positioned at outer kuppe, and part is stretched out outer kuppe.
Described the first rectangle pod apertures and the second rectangle pod apertures have respectively 3, and the area sum of these 6 rectangle pod apertures is greater than 270 square centimeters.
On described outer kuppe surface, have and both prevent that thermal current from quickly diffusing to main fracture, guarantees again the small sircle hole that air-flow is unobstructed.
The internal diameter of described outer kuppe is 250-300cm.
Described interior kuppe has ledge, and this ledge ends in the outer surface of outer kuppe, by this ledge, interior kuppe is connected with external electrical.
Compared with prior art, a kind of kuppe for combined electrical apparatus arc control device of the utility model at least has following beneficial effect: the utility model comprises interior kuppe and outer kuppe, interior kuppe is provided with the first rectangle pod apertures and the second rectangle pod apertures, so, the high temperature free gas that electric arc causes diffuses to outer kuppe from the first rectangle pod apertures and the second rectangle pod apertures, improve the insulation recovery speed between fracture, thereby reduce the size of Shell of circuit breaker in combined electrical apparatus, realize miniaturization object.In other words, the decline of the gas density that the utility model has suppressed to be caused by electric arc, meanwhile, has strengthened the discharge efficiency of hot gas, has further improved medium situation, reaches the object of miniaturization.
[accompanying drawing explanation]
Below in conjunction with accompanying drawing, the utility model is described in further details:
Fig. 1 is the structural representation of a kind of kuppe for combined electrical apparatus arc control device of the utility model.
Wherein: 1 is insulation column; 2 is outer kuppe; 3 is interior kuppe; 4 is contact base; 5 is arcing contact; 6 is contact; 7 is radome; 8 for electrically connecting.
[embodiment]
As shown in Figure 1, the utility model discloses a kind of kuppe for combined electrical apparatus arc control device, comprise coaxial setting insulation column 1, outer kuppe 2, interior kuppe 3, contact base 4, radome 7, be arranged on contact base 4 and be positioned at arcing contact 5 and the contact 6 of radome, and electrically connect 8.Described outer kuppe 2 is fixed on insulation column 1, and described interior kuppe 3 is arranged on outer kuppe 2 inside, and described contact base 4 parts stretch in outer kuppe 2 and contact with interior kuppe 3, and described radome 7 is arranged on end relative with interior kuppe 3 on contact base 4.
Described kuppe has double-deck kuppe: interior kuppe 3 and outer kuppe 2; Interior kuppe 3 and outer kuppe 2 are all fixed on insulation column 1, contact base 4 is connected with interior kuppe 3, its part is positioned at outer kuppe 2, part is stretched out outer kuppe 2, arcing contact 5 and contact 6 are all fixed on contact base 4, within being loaded on radome 7, electrically connecting 8 is the projection of interior kuppe, for being connected with external electrical.
Wherein, there is radial ruler modest ability, the first short rectangle pod apertures of lateral dimension in the centre position of interior kuppe 3, there is the second rectangle pod apertures short with the radial dimension of the first rectangle pod apertures opposite position, that lateral dimension is long at the apical position of interior kuppe 3, these both types, the high temperature free gas that totally 6 rectangular pod apertures (the area sum of 6 rectangle pod apertures is greater than 270 square centimeters) can cause electric arc rapidly diffuses in outer kuppe 2.The internal diameter of described outer kuppe is 250-300cm, and outer kuppe has multiple small sircle holes on 2 surfaces, and this small sircle hole can either prevent that thermal current from quickly diffusing to main fracture, can guarantee that again air-flow is unobstructed.The decline of the gas density that this technical scheme has suppressed to be caused by electric arc, meanwhile, has strengthened the discharge efficiency of hot gas, has further improved medium situation, and the combined electrical apparatus size of space is reduced greatly.
Achievement accordingly, has developed the GIS self energy circuit breaker that domestic first size of space is less than 1600mm, and the size of space dwindles 20%, reaches the object of product miniaturization.
