Abstract
The invention provides a bus connector for a cabinet type gas-insulated metal-enclosed switchgear, which is characterized in that a connector rubber sleeve is inserted between a bus bushing and a bus, the outside of the connector rubber sleeve is pressed tightly by a pressing plate, the pressing plate is fixed on a cabinet side plate by a screw nut B, the bus bushing is fixed on the cabinet side plate by a screw nut A, a sealing ring is arranged in a groove between the bus bushing and the cabinet side plate, and a conductive spring contact finger is arranged in a semi-circle groove between the bus bushing and the bus. When the bus connector is used, epoxy resins are taken as external insulation of a cabinet bus, the elasticity of the bus connector rubber sleeve is utilized to edge out air gaps between the rubber sleeve and the bus bushing as well as between the rubber sleeve and the bus. The bus connector has the advantages that solid insulating materials are used as the external insulation, and the electric-field distribution is reasonable, thus the potentials of different insulating media are exerted sufficiently; the self-compensation and adjustment of installation deviation can be realized, and the installation is convenient and reliable, thus the size of an insulation structure is reduced effectively; and only 10mm is reserved between two cabinets, thus saving the space.
Description
Technical field
What the present invention relates to is that a kind of cabinet type Cubicle Gas-Insulated Switchgear is used bus tie, belongs 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; The control of the connecting method between cabinet and the cabinet, the design Selection of insulating part and installation quality thereof; 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 to be prone to one of link that breaks down in the entire equipment most.The Cubicle Gas-Insulated Switchgear of early development, bus generally are inflation bus or cable bus.They exist on-the-spot difficult installation, autgmentability poor, defective such as cannot plug.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
What the present invention proposed is that a kind of cabinet type Cubicle Gas-Insulated Switchgear is used bus tie; Its purpose is intended to overcome the existing above-mentioned defective of existing equipment, after the present invention uses, and 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 invention: 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, and 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 invention: 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.
