Abstract
The invention discloses an insulating cover which uses vacuum bubble arc extinction and is applied to a solid insulating switch cabinet, and aims to provide the insulating cover used for the solid insulating switch cabinet, wherein the insulating cover is simple in structure, low in production and maintenance cost and good in insulativity, facilitates modularized management and installation of a connecting piece and avoids pollution to the environment caused by the adoption of SF6 gas. The insulating cover comprises a cover body (1), a bus sleeve (2), an inlet and outlet line sleeve (3), a three-position motion cavity and a vacuum bubble cavity, wherein the cover body (1) is formed by pouring epoxy resin, and the three-position motion cavity and the vacuum bubble cavity are formed in the cover body (1). The vacuum bubble cavity is arranged below the three-position motion cavity and communicated with the three-position action cavity, the bus sleeve (2) is communicated with the three-position motion cavity, and the inlet and outlet line sleeve (3) is communicated with the vacuum bubble cavity. The insulating cover can be applied to the field of switch cabinets.
Description
Technical field
The present invention relates to a kind of solid insulation switch cabinet insulating boot that can be applicable to solid insulation switch cabinet field.
Background technology
At present, the 10-35kV switchgears on market adopt gas-insulated ring network cabinet mostly, in gas-insulated ring network cabinet
Arc extinguishing operation is typically employed to SF6（Sulfur hexafluoride）Gas and supporting arc-blowing device.SF6（Sulfur hexafluoride）Gas is international public
One of six kinds of greenhouse gases recognized,《The United Nations's climate change pact》With《The Kyoto Protocol》Greenhouse gas emission is had clearly
Restriction requirement and emission reduction targets；Meanwhile, sulfur hexafluoride can be electrolyzed to produce the toxic gas such as less fluorinated sulfur when switch cut-offs arc extinguishing,
If greatly pollution can be caused in being discharged into atmospheric environment to environment.
In the switch block of existing gas insulation switch cabinet is installed in, due to gas tank volume
Larger, more switch parts, complex structure, processing technique are complicated and higher to the requirement of gas tank air-tightness, so its production, dimension
That what is protected is relatively costly.
The content of the invention
The technical problem to be solved is to overcome the deficiencies in the prior art, it is desirable to provide one kind is gone out using vacuum bubbles
Arc simultaneously applies that simple structure on solid insulation switch cabinet, production and maintenance cost are cheap, insulating properties is good, be easy to connector
Modularization management and install and avoid causing the solid insulation switch cabinet insulating boot of environmental pollution using SF6 gases.
The technical solution adopted in the present invention is：The present invention include by the cover body of poured with epoxy resin, bus casing,
Inlet-outlet sleeve and three station action chambers being arranged on inside the cover body and vacuum bubbles chamber, the vacuum bubbles chamber is arranged on institute
State the lower section in three station action chambers and connect with the three stations action chamber, the bus casing is connected with the three stations action chamber
Logical, the inlet-outlet sleeve is connected with the vacuum bubbles chamber.
Further, the solid insulation switch cabinet insulating boot is internally provided with gathering sill symmetrical before and after at least two groups
The three stations action chamber is separated out three stations interval by group, the gathering sill group, respectively isolating partition, ground connection interval with
And vacuum bubbles interval, the vacuum bubbles chamber is arranged on the lower section at vacuum bubbles interval, the bus casing be arranged on it is described every
Sow discord every lower section.
Further, the solid insulation switch cabinet insulating boot also include being arranged on through hole on the side wall of the cover body and
It is arranged on outside the cover body and for sealing the transparent cover plate of the through hole, arranges between the through hole and the transparent cover plate
There is sealing ring.
Further, the upper surface in the cover body and side wall along the cover body is provided with annular groove, the annular groove
Inside is provided with sealing ring.
Further, the bus casing and the inlet-outlet sleeve are to go out formula structure before taper.
The invention has the beneficial effects as follows：As the present invention includes by the cover body of poured with epoxy resin, bus casing, enters
Outlet casing tube and three station action chambers being arranged on inside the cover body and vacuum bubbles chamber, the vacuum bubbles chamber are arranged on described
The lower section in three station action chambers is simultaneously connected with the three stations action chamber, and the bus casing is connected with the three stations action chamber
Logical, the inlet-outlet sleeve is connected with the vacuum bubbles chamber, so being not difficult to find out, the present invention adopts solid dielectric insulating forms,
Effectively avoid prior art and use SF6（Sulfur hexafluoride）Gas and the potential safety hazard that produces and the pollution to environment；Meanwhile,
The present invention adopts insulant epoxy resin one-time cast-forming, its not only insulating properties it is good, and will not be due to severe
External environment and reduce the grade for insulating, and then cause the generation of security incident.In addition, present configuration is compact, it is simple compact,
It is easy to modularization management and the installation of internal connector, fundamentally reduces maintenance cost and maintenance difficulties.
Further, due to present invention additionally comprises the through hole that is arranged on the side wall of the cover body and being arranged on outside the cover body
Portion the transparent cover plate for sealing the through hole, are provided with sealing ring between the through hole and the transparent cover plate, so this
Invention can be observed to insulating boot inner case on the premise of insulating properties is ensured, and then guarantees the steady of inner body operation
It is fixed.
Further, the upper surface of the cover body and side wall along the cover body is provided with annular groove, in the annular groove
Portion is provided with sealing ring, and the sealing ring may further ensure that overall insulating properties.
Further, as the bus casing and the inlet-outlet sleeve are to go out formula structure before taper, so the present invention is more
It is easy to the installation and maintenance of cable connector head.
