Abstract
The utility model relates to a box type sulfur hexafluoride switch cabinet, which is composed of a cabinet body, a main loop switch, an electrified accessory chamber, a fuse chamber, an operating mechanism chamber and a cable chamber, wherein the utmost upper part of the switch cabinet is provided with the fuse chamber, the middle part of the switch cabinet is provided with the operating mechanism chamber, the main loop switch and the electrified accessory chamber which are positioned behind the operating mechanism chamber, and the entire space of the lower part of the switch cabinet is provided with the cable chamber. The utility model is characterized in that the main loop switch and the electrified accessory chamber are a sealed box body filled with SF< 6 > gas. Because the utility model has the adoption that the main loop switch and electrified accessories are all fixed in the SF< 6 > gas sealed box body, which just makes up for the defects of the switch of air type and other types, the utility model can satisfy the insulation distance of all the electrified accessories, can enable the size of the entire switch cabinet to shrink, and really lives up to all insulation, all working condition, no need of maintenance, and high reliability.
Description
Technical field
The utility model belongs to a kind of High-Voltage Electrical Appliances power distribution cabinet, particularly a kind of box sulphur hexafloride circuit breaker cabinet.
Background technology
The looped network wiring is the typical wiring pattern of China's city 12kV electrical network, and looped network switch apparatus is the developing direction of transformation, newly-built distribution, realizes the inherent requirement of distribution automation especially.Looped network switch apparatus mostly adopts on-load switch and on-load switch-fuse combined electric apparatus thereof, and this is because it has more excellent technical-economic index and distribution transformer short-circuit protection performance than circuit breaker.At present, China's distribution realizes that the looped network wiring mainly contains air class and sulphur hexafluoride (SF
6) switch cubicle such as class.Air class switch cubicle is simple in structure, and is cheap, but volume is big, and insulation and arc extinction performance are poor, and maintenance is very big.Along with the continuous increase of net capacity, the user more and more lays particular stress on the break performance of switch, has promoted SF objectively
6The using and popularizing of switch.SF
6Switch has good break performance, and the volume ratio air switch greatly reduces, but owing in whole switch cubicle, also have other charged annex (as line row) need satisfy its insulation distance, even used SF
6Switch, the volume of switch cubicle is still bigger.
Summary of the invention
The purpose of this utility model provides a kind of insulation distance that can satisfy all charged annexes, can make the box sulphur hexafloride circuit breaker cabinet of whole switch cubicle volume-diminished again, to overcome above-mentioned deficiency.
To achieve these goals, the utility model is by cabinet, major loop switch and charged annex chamber, fuse chamber, four parts in operating mechanism chamber and cable vault are formed, wherein the top is the fuse chamber, the centre is operating mechanism chamber and major loop switch that is positioned at back, mechanism chamber and charged annex chamber, the most whole space of below then is the cable vault, and be characterized in: major loop switch and charged annex chamber are seal cases, are full of SF in the seal case
6Gas;
Action bars in the aforesaid operations mechanism chamber is connected with the action bars of major loop switch in the seal case by a bellows, wherein an opening of bellows is close solid on the housing of seal case, the action bars of major loop switch is separately fixed at the both sides of metal derby in the close intrinsic metal derby on another opening, action bars in the operating mechanism chamber and seal case;
Also be provided with inflation inlet and venting on the housing of above-mentioned seal case.
Because the utility model adopts major loop switch and charged annex all to be fixed on a SF
6In the air seal casing, just in time remedied the shortcoming of air class and other switches, made the utility model can satisfy the insulation distance of all charged annexes, can make whole switch cubicle volume-diminished again, all insulation, full operating mode have really been accomplished, non-maintaining, high reliability.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the utility model bellows syndeton schematic diagram.
Embodiment
Further specify the utility model below in conjunction with drawings and Examples.
The utility model is by cabinet, and major loop switch and charged annex chamber 1, fuse chamber 2,4 four parts in operating mechanism chamber 3 and cable vault are formed.The top is fuse chamber 2, and the centre is operating mechanism chamber 3 and the seal case 1 that is positioned at 3 back, operating mechanism chamber, and the most whole space of below then is cable vault 4.Seal case 1 joins by the fuse pipe box on its top and the fuse in the fuse chamber 2.And the operation of three position on-load switches in the seal case 1 is to be finished by the action of the bellows 5 of its front portion of operating mechanism control, wherein an opening of bellows 5 is close solid on the housing 1.1 of seal case 1, a close intrinsic metal derby 6 on another opening, the action bars of major loop switch is separately fixed at the both sides of metal derby 6 in action bars 3.1 in the operating mechanism chamber and the seal case 1, and inner turnover line then is that inlet wire, the feeder line sleeve pipe by seal case 1 preceding bottom cooperates the plug-in type elbow type plug in the cable vault to be connected with cable.In the bottom of seal case 1 inflation inlet and venting are arranged, be respectively applied for inner SF
6Pressure release when replenish and the internal pressure of gas increases to above critical value suddenly.Only when fuse 2 of chambers and Xiamen were closed, fusing chamber interlocking device in the operating mechanism chamber 3 and switch and Xiamen interlocking device discharged the utility model, and spring operating mechanism can move.This moment the operating spring operating mechanism, the action of the bellows 5 that links to each other with seal case 1 by operating mechanism, thus control the branch of three position on-load switches-close-ground connection.
Bellows 5 welded seal structures (Fig. 2) are adopted in the utility model operation part sealing, when having solved conventional employing static and dynamic sealing circle sealing, and the gas leakage that this place causes owing to relative motion wearing and tearing and ageing of rubber.Then adopted sleeve pipe and the hermetically sealed welding of casing to solve the gas leakage maintenance issues that conventional employing seal washer brings in turnover line coupling part.
It is known that the content that is not described in detail in this specification belongs to this area professional and technical personnel
Prior art.
