Abstract

The utility model relates to a bus connector for a cubicle gas-insulated metal-enclosed switchgear. The bus connector is characterized in that a connector rubber sleeve is inserted between a bus bushing and a bus, the outer side of the connector rubber sleeve is compressed by pressure plates, the pressure plates are fixed to cubicle side plates through nuts B, the bus bushing is fixed to the cubicle side plates through nuts A, a sealing ring is mounted in each of grooves between the bus bushing and the cubicle side plates, and a conductive spring contact is mounted in each of semicircular grooves between the bus bushing and the bus. When the bus connector is used, epoxy resin is used as outer insulation for the cubicle bus, and clearances among the bus bushing, the rubber sleeve and the bus are squeezed off by the aid of the elastic bus connector rubber sleeve. The bus connector has the advantages that solid insulating materials are used as outer insulation, electric field layout is reasonable, potentials of different insulating media are fully utilized, mounting errors of the bus connector can be compensated and adjusted automatically, the bus connector is simple and reliable in mounting, the size of the insulation structure is reduced effectively, and only a 100mm distance needs to be reserved between two cubicles so that excessive space is not occupied.

Description

A kind of cabinet type Cubicle Gas-Insulated Switchgear bus tie
Technical field
The utility model relates to a kind of cabinet type Cubicle Gas-Insulated Switchgear bus tie, belong to cabinet type Cubicle Gas-Insulated Switchgear technical field.
Background technology
In the process that the design and installation of cabinet type Cubicle Gas-Insulated Switchgear are used, connecting method between cabinet and the cabinet, the design of insulating part are selected for use and the control of installation quality, it is the emphasis that product design personnel and project installation personnel consider always, this is that its technical merit directly has influence on the fail safe and the reliability of integral device because insulating part is one of link that the most easily breaks down in the entire equipment.The Cubicle Gas-Insulated Switchgear of early development, bus generally are inflation bus or cable bus.There are the on-the-spot defectives such as difficult, that autgmentability is poor, cannot plug of installing in they.Recent years, develop a kind of solid insulation bus abroad, solved above-mentioned shortcoming.It is big that but its existence takes up room, and installation accuracy requires high, shortcomings such as cost height.Limited its occupation rate of market.
Summary of the invention
The utility model proposes a kind of cabinet type Cubicle Gas-Insulated Switchgear bus tie, its purpose is intended to overcome the existing above-mentioned defective of existing equipment, after the present invention uses, can self-compensating and regulate installation deviation, simple installation, reliable in quality has good insulation property and barrier propterty simultaneously, improves the reliability and the fail safe of equipment.
Technical solution of the present utility model: it is characterized in that: connector gum cover inserts between bus casing and the bus, the connector gum cover outside compresses with pressing plate, pressing plate is fixed on the side cabinet with the B nut, bus casing is fixed on the side cabinet with the A nut, in the groove between bus casing and side cabinet sealing ring is installed, the power spring fingertip is housed in the half slot between bus casing and bus.
With the external insulation of epoxy resin as the cabinet bus, bus is to utilize bus connector gum cover to insert between cabinet bus casing and the bus with the connection of cabinet.Utilize the elasticity of bus connector gum cover that the air gap between gum cover and bus casing, gum cover and the bus is squeezed out.Thereby reach the purpose of interface insulation.
Advantage of the present utility model: use solid insulating material as external insulation, Electric Field Distribution is reasonable, has given full play to the potentiality of different insulative medium.Simultaneously can self-compensating and regulate installation deviation, simple installation, reliable has reduced the size of insulation system effectively.The present invention only needs to reserve between the cabinet of two sides the distance of 100mm, does not take other space.
Description of drawings
Accompanying drawing 1 is the structural representation of cabinet type Cubicle Gas-Insulated Switchgear with bus tie.
Among the figure 1 is connector gum cover, the 2nd, bus casing, the 3rd, bus, the 4th, A nut, the 5th, side cabinet, the 6th, pressing plate, the 7th, B nut, the 8th, sealing ring, the 9th, spring touch finger, the 10th, external shroud, the 11st, insulating barrier, the 12nd, internal shield, the 13rd, circular arc drum type, the 14th, the step, the 15th of projection, screen, the 16th, screen, the 17th, conductive seat, the 18th, insulated leg, the 19th, mounting flange.
Embodiment
The contrast accompanying drawing, its structure is that connector gum cover 1 inserts between bus casing 2 and the bus 3, connector gum cover 1 outside compresses with pressing plate 6, pressing plate 6 usefulness B nuts 7 are fixed on the side cabinet 5, bus casing 2 usefulness A nuts 4 are fixed on the side cabinet 5, sealing ring 8 is installed in the groove between bus casing 2 and side cabinet 5, in the half slot between bus casing 2 and bus 3 power spring fingertip 9 is housed.
Bus tie is the element that the galvanic circle of two sides cabinet is connected.And to guarantee that the gas-insulated medium in the cabinet is not leaked to the cabinet outside.
