Preferably, in above-mentioned a kind of gas-insulated ac metal closing switch gear, in described independently gas tank, insulating gas SF6 is full of.
Preferably, in above-mentioned a kind of gas-insulated ac metal closing switch gear, one end of described cabinet arranges an aperture, and described in making, independently the SF6 gas atmosphere of gas tank and described cabinet inside is consistent.
Preferably, in above-mentioned a kind of gas-insulated ac metal closing switch gear, in described operating mechanism, be provided with the on-load switch that model is CY-FLN36-40.5/T630, and adopt resin-cast to insulate and SF6 gas double insulation arc extinguishing.
Preferably, in above-mentioned a kind of gas-insulated ac metal closing switch gear, described in described operating mechanism is fixed on by fixed mount independently in the middle of gas tank.
Preferably, in above-mentioned a kind of gas-insulated ac metal closing switch gear, the line of described inlet-outlet line device can enterprising on go out, upper entering and lower leaving, bottom in and top out, under enter under the free way that goes out.
Preferably, in above-mentioned a kind of gas-insulated ac metal closing switch gear, the on-load switch of described operating mechanism and the line of described inlet-outlet line device are by expand and copper bar is connected, the copper bar heat-shrink tube that on-load switch is connected with expansion and full skirt insulate, and the use standard of copper bar is 3 (60 × 6).
Known via above-mentioned technical scheme, compared with prior art, the utility model openly provides a kind of gas-insulated ac metal closing switch gear, it is one of visual plant in pressure equipment for power transmission and distribution, break the arc extinguishing insulation of traditional pure gas, but adopt resin-cast insulation and SF6 gas double insulation arc extinguishing, insulation effect is better, and with CY-FLN36-40.5/T630 on-load switch for main element, arc extinguishing insulation dual fail-safe, dispensing can be continued more stable, more reliable electric energy, change the model of traditional all insulation totally enclosed type gas-filling cabinet in appearance, use independently gas tank, and the structure of gas tank is made up of case raising middle flask, instead of the exposed on-load switch in gas tank inside of tradition, but covered with cabinet, outward appearance is more novel, more reasonable structure.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiment of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to the accompanying drawing provided.
Fig. 1 accompanying drawing is structural representation of the present utility model.
In FIG, 1 be independently gas tank, 2 be cabinet, 3 be operating mechanism, 4 for inlet-outlet line device.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
The utility model embodiment discloses a kind of gas-insulated ac metal closing switch gear, specifically comprises: independently gas tank 1; Be arranged at the cabinet 2 that independently gas tank 1 is middle; Be configured in the operating mechanism 3 in cabinet 2; Inlet-outlet line device 4.
First the utility model changes traditional all insulation totally enclosed type gas-filling cabinet, adopt box structure in case, setting operation mechanism cabinet in the middle of independently gas tank, the on-load switch that instead of in traditional operating mechanism is exposed in gas tank, and an aperture is set on cabinet, not only can keep the stable of air pressure, and the leakage of gas can be prevented; It is single that next has departed from dielectric, and use resin-cast insulation and SF6 gas double insulation arc extinguishing, decrease exposed charged area, better, coefficient of safety is higher for insulation effect.
In order to optimize technique scheme further, be independently full of insulating gas SF6 in gas tank 1, this gas is colourless, tasteless, nontoxic, has excellent insulation property, and can not the inert gas of aged deterioration.
In order to optimize technique scheme further, one end of cabinet 2 arranges an aperture, and independently gas tank 1 is consistent with the SF6 gas atmosphere of cabinet 2 inside, and such design safety factor (DSF) is higher, avoids the sudden change because of pressure to cause the leakage of gas.
In order to optimize technique scheme further, be provided with the on-load switch that model is CY-FLN36-40.5/T630 in operating mechanism 3, and adopt resin-cast to insulate and SF6 gas double insulation arc extinguishing, change the dielectric arc extinguishing that tradition is single, insulation effect is better, safer.
In order to optimize technique scheme further, it is middle that operating mechanism 3 is fixed on independently gas tank 1 by fixed mount, and from amechanical angle, uniform force, fixed effect is better.
In order to optimize technique scheme further, the line of inlet-outlet line device 4 can enterprising on go out, upper entering and lower leaving, bottom in and top out, under enter under the free way that goes out, such selectivity is stronger, handled easily.
In order to optimize technique scheme further, the on-load switch of operating mechanism 3 and the line of inlet-outlet line device 4 are by expand and copper bar is connected, the copper bar heat-shrink tube that on-load switch is connected with expansion and full skirt insulate, the use standard of copper bar is 3 (60 × 6), surface area is large, good heat dissipation, can boring be connected with in dish cabinet, part is convenient, the advantages such as the maximum utilization dish cabinet space of energy.。
