Abstract
A solid insulated switchgear consists of a casing, a breaker, a three station isolating/grounding switch, a bus, a connecting conductor, a current transformer, and a cable; wherein the breaker and the three station isolating/grounding switch of the solid insulated switchgear are combined into a whole and share a solid insulated housing; a conductive connecting piece between the breaker and the three station isolating/grounding switch is sealed, thereby reducing components, movable members and an assembling process, raising operating safety of the solid insulated switchgear, at the same time, spatial sizes of the breaker and the three station isolating/grounding switch are greatly reduced, thus the solid insulated switchgear becomes more miniaturized; in addition, a solid insulating material is coated on other components to serve as an external insulation, then a layer of semiconductive material is sprayed on a surface of the solid insulating material to serve as a ground layer, thus the solid insulated switchgear has the advantages of excellent insulating property, safety, and reliability; a plug-in type connection is adopted between the components, thus assembling adjustment and maintenance become more convenient.
Description
Technical field

Background technology
The insulation property of medium voltage switchgear equipment and volume are two principal elements of restriction medium voltage switchgear equipment development; Around above-mentioned two principal elements, air external insulation-compound inslation-gas-insulated-solid insulation stage has been experienced in the development of medium voltage switchgear equipment technology.Solid-state insulated switchgear is a kind of switchgear that new development is in recent years got up, and it has, and volume is little, reliability Gao Bingneng reduces greatly and reduce the maintenance frequency, prolong advantages such as time between overhauls(TBO), have a extensive future, and also be the inexorable trend of switch industry development.
Existing solid-state insulated switchgear; Circuit breaker and three-station isolating/grounding switch are modules independently separately; Its advantage is that modular combination is flexible, but the conducting connecting part in the middle of also needing between the two, thereby increased parts, movable piece and assembling link; Simultaneously also brought unsafe factor to equipment operation; And the space that its volume size dwindles in addition needs further optimal design thus again, reduces a kind of solid-state insulated switchgear of parts, movable piece and assembling link as far as possible.
Summary of the invention
The purpose of the utility model provides a kind of solid-state insulated switchgear that circuit breaker, three-station isolating/grounding switch are combined into one; Technical problem to be solved is an optimal design; Reduce parts, movable piece and assembling link; With the safe operation of raising equipment, and the compact apparatus of trying one's best.
The technical scheme that the utility model adopted is:
A kind of solid-state insulated switchgear; Mainly form by casing, circuit breaker, three-station isolating/grounding switch, bus, bonding conductor, current transformer and cable; It is characterized in that: described circuit breaker and three-station isolating/grounding switch are combined into one and are installed in the casing; Described circuit breaker, three-station isolating/grounding switch and the conducting connecting part between them are through solid envelope, and a shared solid insulation housing is made external insulation.
Preferred version as the utility model:
Said bus is a T type structure, and first end and second end at two are fixed on the casing, and the 3rd middle end is connected with three-station isolating/grounding switch.
Link to each other through bonding conductor between said circuit breaker and the current transformer, current transformer links to each other with cable.
Said bus, bonding conductor and cable are the plug-in type parts, and they adopt plug-in type, adjustment convenient for assembly and repair and maintenance on connecting;
The skin of said bus, bonding conductor, current transformer and cable all adopts solid insulating material to coat and makes external insulation;
All be coated with the tangibly ground plane of one deck semiconductive on the solid insulating layer of solid insulation housing, bus, bonding conductor, current transformer and cable outer layer that said circuit breaker and three-station isolating/grounding switch are shared, with the safe electronegative potential of acquisition personnel contact.
Adopt above-mentioned solid-state insulated switchgear, owing to circuit breaker, three-station isolating/grounding switch are combined into one, and a shared solid insulation housing is made external insulation; Conducting connecting part between circuit breaker, three-station isolating/grounding switch has also carried out solid envelope; Thereby reduced parts, movable piece and assembling link, the fail safe that has improved equipment operation, simultaneously; The bulk of circuit breaker and three-station isolating/grounding switch is dwindled greatly, and equipment is miniaturization more; In addition, make external insulation, and make ground plane at solid insulating material surface spraying one deck semiconductive material, apparatus insulated excellent performance, safety, reliable because other components and parts also adopt solid insulating material to coat; The socket connection that interelement adopts, assembling adjustment and repair and maintenance are convenient.
