Abstract
The utility model relates to a bus connecting sleeve tube of a switch cabinet, and belongs to the fields of a switchboard, a substation or a switch device for electricity supply or electricity distribution. The bus connecting sleeve tube of a switch cabinet comprises an epoxy-resin outer sleeve and an electric conductor, wherein, the electric conductor is arranged in the outer sleeve. One end of the electric conductor is provided with a connecting head, and the other end thereof is provided with a screw hole. The rear end of the outer sleeve is provided with a jack and a mounting hole, and the front end thereof is provided with a conical hole. The connecting head of the electric conductor is arranged at the center of the conical hole, and a conical groove is formed between the inner hole of the conical hole of the outer sleeve and the electric conductor. The utility model has the advantages of simple structure and reasonable design, and solves the problem of the transition of the gas insulation bus to the air insulation bus in the ring main unit, thus realizing the purposes of combined use of the air insulation cabinet and the gas insulation cabinet.
Description
Technical field
The utility model switch cubicle bus joint sleeve belongs to distribution board, transformer station or the switching device field that power supply or distribution are used, and particularly relates to a kind of bus connected mode.
Background technology
For distribution field widely used ring main unit, its bus connected mode is common two kinds of air insulation and gas-insulateds, and gas-insulated generally is meant uses SF6 gas as dielectric, so that reduce electric clearance significantly, thereby reduces the switch cubicle volume.The ring main unit gas insulated bus is when the transition of air insulation bus, since bus in gas electric clearance and creepage distance than much smaller in the air, therefore bus needs a suitable media just can reach air-insulated requirement to the air insulation transition time, and existing simple employing air insulation or gas isolated bus tie all are not suitable for as the media of gas insulated bus to the transition of air insulation bus.
Summary of the invention
The purpose of this utility model is to avoid the deficiencies in the prior art part, provide a kind of ring main unit gas insulated bus that is suitable for to the transition of air insulation bus, with the supporting use of bus tie, realize the switch cubicle bus joint sleeve of transition effectively from the gas-insulated mode to the air insulation mode.
The purpose of this utility model reaches by following measure, switch cubicle bus joint sleeve of the present utility model is made up of epoxy resin overcoat and electric conductor, electric conductor is arranged in the overcoat, one end of electric conductor has connector, the other end has screw, there is a jack rear end of overcoat, be used for inserting copper bar, on the rear end of overcoat installing hole is arranged, bolt comes on the screw of electric conductor by the installing hole fixed copper, the front end of overcoat is provided with bellmouth, the connector of electric conductor is at the bellmouth center, forms the ring-type cone tank between the bellmouth inwall of overcoat and the electric conductor, when bus tie is inserted in the bellmouth of overcoat, bellmouth and bus tie adopt taper fit, and the connector of electric conductor keeps closely being connected with bus tie.With the condition of metal cabinet insulation under, realize being electrically connected of air insulation cabinet and gas-insulated cabinet.
The utility model is provided with circular port at the bellmouth front end of overcoat, conveniently is connected with bus tie.
The utility model is provided with annular full skirt at the outer surface of overcoat, increases creepage distance.
The utility model is simple in structure, reasonable in design, gas insulated bus is to the problem of air insulation bus transition in the solution ring main unit, meet the requirement of insulation, can realize transition effectively, thereby realize the purpose that air insulation cabinet and gas-insulated cabinet and cabinet use from gas insulated bus to the air insulation bus.
