Abstract
The utility model discloses an insulating cover extinguishing arc with a vacuum bubble and applied to a solid insulating switch cabinet, and is aimed at providing an insulating cover for a solid insulating switch cabinet, wherein the insulating cover has advantages of simple structure, low production and maintenance cost, good insulating performance, convenient connector modular management and installation, and prevention of environmental pollution caused by using SF6 gas. The insulating cover comprise a cover body (1) formed by pouring epoxy resin, a bus sleeve (2), an inlet and outlet wire sleeve (3), and a three-position operation chamber and a vacuum bubble chamber disposed in the cover body (1). The vacuum bubble chamber is disposed under the three-position operation chamber and is communicated with the three-position operation chamber. The bus sleeve (2) is communicated with the three-position operation chamber. The inlet and outlet wire sleeve (3) is communicated with the vacuum bubble chamber. The insulating cover can be used in switch cabinet field.
Description
Technical field
The utility model relates to a kind of solid insulation switch cabinet insulating cover that can be applicable to solid insulation switch cabinet field.
Background technology
At present, the 10-35kV switchgear on market adopts gas-insulated ring network cabinet mostly, and the arc extinguishing operation in gas-insulated ring network cabinet will adopt SF6(sulphur hexafluoride conventionally) gas and supporting arc-blowing device.SF6(sulphur hexafluoride) gas is one of internationally recognized six kinds of greenhouse gas, " the United Nations's climate change pact " and Kyoto Protocol all have clear and definite restriction to require and reduce discharging target to greenhouse gas emission; Meanwhile, sulphur hexafluoride can be electrolyzed to produce the toxic gases such as low sulfur fluoride in the time that switch cut-offs arc extinguishing, can cause great pollution to environment if be discharged in atmospheric environment.
The switch block of existing gas insulation switch cabinet be installed in form with Plate Welding in, because gas tank volume is large, switch parts are more, complex structure, processing technology is complicated and gas tank air-tightness is had relatively high expectations, so its cost of producing, safeguarding is higher.
Utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, aims to provide a kind ofly to utilize vacuum bubbles arc extinguishing and be applied in simple in structure, the production on solid insulation switch cabinet and maintenance cost is cheap, insulating properties good, be convenient to connector modularization management and installation and avoid adopting SF6 gas and the solid insulation switch cabinet insulating cover that causes environmental pollution.
The technical scheme that the utility model adopts is: the utility model comprises cover body, bus casing, the inlet-outlet sleeve being formed by poured with epoxy resin and is arranged on three station action chamber and vacuum bubbles chambeies of described cover body inside, described vacuum bubbles chamber is arranged on the below in described three station action chambeies and is communicated with described three station action chambeies, described bus casing is communicated with described three station action chambeies, and described inlet-outlet sleeve is communicated with described vacuum bubbles chamber.
Further, described solid insulation switch cabinet is provided with at least two symmetrical gathering sill groups in groups front and back with insulating cover inside, described three station action chambeies are separated out three station intervals by described gathering sill group, be respectively isolating partition, ground connection interval and vacuum bubbles interval, described vacuum bubbles chamber is arranged on the below at described vacuum bubbles interval, and described bus casing is arranged on the below of described isolating partition.
Further, described solid insulation switch cabinet also comprises the through hole on the sidewall that is arranged on described cover body and is arranged on described cover body outside and for sealing the transparent cover plate of described through hole, between described through hole and described transparent cover plate, is provided with sealing ring with insulating cover.
Further, be provided with annular groove at the upper surface of described cover body and along the sidewall of described cover body, described annular groove inside is provided with sealing ring.
Further, described bus casing and described inlet-outlet sleeve are to go out formula structure before taper.
The beneficial effects of the utility model are: because the utility model comprises the cover body being formed by poured with epoxy resin, bus casing, inlet-outlet sleeve and be arranged on three stations actions chamber and vacuum bubbles chambeies of described cover body inside, described vacuum bubbles chamber is arranged on the below in described three station action chambeies and is communicated with described three station action chambeies, described bus casing is communicated with described three station action chambeies, described inlet-outlet sleeve is communicated with described vacuum bubbles chamber, so be not difficult to find out, the utility model adopts solid dielectric insulation form, effectively avoid prior art to use SF6(sulphur hexafluoride) gas and the potential safety hazard that produces and the pollution to environment, meanwhile, the utility model adopts insulating material epoxy resin one-time cast-forming, and not only insulation property are good for it, and can not reduce due to severe external environment the grade of insulation, and then cause the generation of security incident.In addition, the utility model compact conformation, simply small and exquisite, be convenient to modularization management and the installation of interconnect, fundamentally reduce maintenance cost and maintenance difficulties.
Further, because the utility model also comprises the through hole on the sidewall that is arranged on described cover body and be arranged on described cover body outside and for sealing the transparent cover plate of described through hole, between described through hole and described transparent cover plate, be provided with sealing ring, so the utility model can be observed insulating cover inner case under the prerequisite that guarantees insulating properties, and then guarantee the stable of inner body operation.
Further, the upper surface of described cover body and the sidewall along described cover body are provided with annular groove, and described annular groove inside is provided with sealing ring, and described sealing ring can further be guaranteed overall insulating properties.
Further, because described bus casing and described inlet-outlet sleeve are to go out formula structure, the installation of cable connector head and maintenance so the utility model is more convenient for before taper.
