Abstract

A wall feed-through sleeve of a soft supporting bus for high voltage switching equipment comprises an inner side part and an outer side part, wherein the inner side part is a ring pipe made of soft supporting conductive rubber playing the roles of supporting and fixing, the inner side part plays the role of supporting a high voltage bus and offering radial fixing to the high voltage bus, as well as eliminating noises caused by bus vibrations during electrified operations, in addition, the conductive rubber of the inner side part is electrically communicated with the bus and an inner shading ring of the outer side part, so as to enable the inner shading ring and a conductor of the bus to be isoelectric; the outer side part serves as the shielding and insulating part of the sleeve, and includes a sleeve cast by epoxy resin as well as the inner shading ring and an outer shading ring cast inside the sleeve; and the outer side part plays the role of optimizing a wind farm and providing sleeve installation.

Description

A kind of high voltage switchgear is with soft support bus wall bushing
Technical field
The utility model relates to a kind of high voltage switchgear in the metal enclosed switchgear with soft support bus wall bushing.
Background technology
Metal enclosed switchgear, its inside are equipped with high pressure elements such as circuit breaker, on-load switch, on-load switch-current limiting fuse combined electrical apparatus, isolating switch or earthed switch, and they form complete high voltage switchgear jointly.
The installation of each high voltage device in cabinet is electrically connected by main bus bar and branch bar.For the switchgear of 40.5kV electric pressure, it is very crucial how solving Insulation Problems.In addition, under the situation that guarantees dielectric strength, the installation of bus copper bar, fixed form and the mode of introducing in the cabinet are just very crucial.At present high voltage bus wall bushing insulation system complexity, support unreasonable.
Summary of the invention
The purpose of this utility model be to provide a kind of simple in structure, effectively reduce electric field strength, the high voltage switchgear that improves insulating reliability is with soft support bus wall bushing.
For achieving the above object, the technical solution used in the present invention is: comprise the sleeve pipe of poured with epoxy resin and be cast in the interior inside and outside shading ring of this sleeve pipe, be provided with the endless tube that the conductive rubber of soft support is made in inner shield ring inboard, bus is by passing in the described endless tube.
The utility model consists of inside and outside two parts, inside part is the endless tube of being made by the conductive rubber that works the soft support of supporting and fixing, its effect is that high voltage bus is formed support and provides radially fixing, and the noise that the bus vibrations bring when eliminating charging operation, in addition, the conductive rubber of inside part is communicated with the inner shield ring of bus and Outboard Sections on electric, makes the conductor equipotential of inner shield ring and bus; Outboard Sections is the shielding and the insulated part of sleeve pipe, is made up of the sleeve pipe of poured with epoxy resin and the inside and outside shading ring that is cast in this sleeve pipe, and its effect is to be optimized and to provide sleeve pipe to install to electric field.
The utility model changes the coaxial electric field distribution into by the vertical electric field distribution that electric Field Optimization is about to common wall bushing, can effectively reduce electric field strength, improves insulating reliability.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
Referring to Fig. 1, the utility model comprises the sleeve pipe 1 of poured with epoxy resin and is cast in inside and outside shading ring 4,2 in this sleeve pipe 1, is provided with the endless tube 3 that the conductive rubber of soft support is made in inner shield ring 4 inboards, and bus 6 is by passing in the described endless tube 3.
Wherein, 1 is the poured with epoxy resin part of high voltage bus wall bushing, and its effect is to provide main insulation and support for bushing; 2 are the external shield ring; 3 endless tubes of making for the conductive rubber of soft support, its effect are that bus 6 is provided support with inner shield ring 4 equipotentials and to bus, reduce the noise of bus when through-flow; 4 are the inner shield ring, and its effect is and 2 actings in conjunction of external shield ring to make that the electric field of wall bushing is a coaxial electric field, evenly distribution of electric field like this; 5 is the thermal shrinkable sleeve or the sulfuration coat of the insulation usefulness of bus outer wrapping, and its effect is the reinforced insulation to bus.
The utlity model has following beneficial effect:
1, compact conformation, all sleeve structures all are arranged together compactly, have avoided in disorder design;
2, good looking appearance, complete function. This sleeve structure is both artistic and practical, and part can also provide support for bus except the usefulness as the high voltage bus insulating sleeve.
3, easy to process, this sleeve structure simplicity of design does not have high-leveled and difficult part and high-precision part requirement, and processing is simple.
But effective noise reduction function when 4, moving. Since adopt soft supporting, so that busbar shakes minimizing when through-flow, noise in the time of can effectively reducing operation.
5, suitable use from little electric current to heavy current busbar.
