Abstract
The utility model relates to a 12kv reinforced insulation switch cabinet for a high altitude area. In a metal enclosed casing, a main circuit is composed of a bus, a branch bus, a vacuum circuit breaker handcart, a contact box, a voltage transformer and an earth switch correspondingly assembled, and is equipped with a fixed supporting insulating part and an overlap valve. An epoxy resin insulating layer with the thickness of more than or equal to 0.8 mm is formed on the surface of the bus and the branch bus, the edge of the overlap valve and one surface opposite to the contact box, insulating covers with corresponding shapes and sizes are respectively enclosed at the overlapping position of the bus and the branch bus and the connecting position of the branch bus and the fixed supporting insulating part, and the break length of the earth switch is increased to be more than or equal to 144 mm. In the switch cabinet, the air insulation structure of the main conductive circuit is improved and strengthened to be suitable for the areas with the high altitude of 2500m.
Description
Technical field
The utility model is a kind of 12kV switch cubicle of reinforced insulation performance, especially is fit to the 12kV air insulation switch cubicle that use the high altitude localities.
Background technology
There is the territory of 2/3rds areas in China more than height above sea level 1000m reaches, and the electric switch equipment of design and use is applicable to below the height above sea level 1000m usually, can not adapt in the high altitude localities and use.Height above sea level increases and will make the dielectric strength of air reduce, thereby influences the electric property and the security reliability of electric switch equipment.The dielectric strength nargin of present 12kV air insulation switch cubicle is less, entering the high altitude localities uses, except using the components and parts that are fit to the high altitude localities instead, also must improve the insulation system form of switch cubicle inner conductive parts, strengthen its insulation property, to guarantee the electric property and the security reliability of equipment.
The utility model content
Be not suitable for the deficiency used in the high altitude localities in order to overcome common 12kV air insulation switch cubicle, the utility model provides a kind of 12kV air insulation switch cubicle of reinforced insulation performance, its technical scheme that adopts is: the insulation system form of improving and strengthen the inner major loop electric conductor insulation of switch cubicle weak part: with the major loop conducting copper, cover valve and carry out vulcanizing treatment respectively, solidify to form the epoxy resins insulation layer at their suitable position; Seal up insulating cover at major loop conducting copper overlapping part and fixed support position thereof; The fracture of earthed switch is opened apart from increasing.
A kind of high altitude localities 12kV switch cubicle of reinforced insulation, in metal enclosed shell, major loop is made of bus, branch bar, vacuum circuit-breaker handcart, contact box, voltage transformer, the corresponding assembling of earthed switch, and the fixed support insulating part is housed and covers valve, it is characterized in that: at the surface of bus and branch bar and the thick epoxy resins insulation layer of one side sulfuration formation 〉=0.8mm of edge that covers valve and relative contact box thereof.
Wherein, the insulating cover of sealing up correspondingly-shaped and size respectively at the connecting portion of overlapping part, branch bar and its fixed support insulating part of bus and branch bar.
Wherein, the fracture of earthed switch is opened apart from increasing to 〉=144mm.
The utility model is simple and practical, and it can strengthen the insulation property of 12kV air insulation switch cubicle, has to improve the beneficial effect of switch cubicle in the security reliability of high altitude localities use.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the total structure schematic diagram of the utility model embodiment.
Fig. 2 is the schematic diagram that insulating cover is sealed up at the female copper bar of embodiment, branch's copper bar overlapping part and fixed support position.
Among the figure: 1. female copper bar, 2. branch's copper bar, 3. fixed support insulating part, 4. contact box, 5. voltage transformer, 6. earthed switch 7. covers valve, 8. vacuum circuit-breaker handcart, 9. insulating cover.
Embodiment
Present embodiment is suitable for high height above sea level to the area of 2500m to be used, in its metal enclosed shell, major loop is by bus (1), branch bar (2), vacuum circuit-breaker handcart (8), contact box (4), voltage transformer (5), the corresponding assembling of earthed switch (6) constitutes, and fixed support insulating part (3) is housed and covers valve (7), vulcanizing treatment is carried out with the one side of edge that covers valve (7) and relative contact box (4) thereof in surface at switch cubicle bus (1) and branch bar (2), solidify to form 〉=epoxy resins insulation layer that 0.8mm is thick, and at the overlapping part of bus (1) with branch bar (2), the insulating cover (9) that the connecting portion of branch bar (2) and its fixed support insulating part (3) is sealed up correspondingly-shaped and size respectively, the fracture of earthed switch (6) is opened apart from increasing to 〉=144mm, to improve and to strengthen the air insulation structural form of switch cubicle major loop conductive component.
Claims (3)
1. the high altitude localities 12kV switch cubicle of a reinforced insulation, in metal enclosed shell, major loop is made of bus, branch bar, vacuum circuit-breaker handcart, contact box, voltage transformer, the corresponding assembling of earthed switch, and the fixed support insulating part is housed and covers valve, it is characterized in that: at the surface of bus and branch bar and the thick epoxy resins insulation layer of one side sulfuration formation 〉=0.8mm of edge that covers valve and relative contact box thereof.
2. the high altitude localities 12kV switch cubicle of a kind of reinforced insulation according to claim 1 is characterized in that: the insulating cover of sealing up correspondingly-shaped and size respectively at the connecting portion of overlapping part, branch bar and its fixed support insulating part of bus and branch bar.
