Abstract
The utility model discloses a kind of busbar formula composite bushings, it designs the main shirt rim including surface, using lengthening creep distance design on the right side of busbar formula composite bushing, ensure creepage distance ＞ 240mm, and insulation clear distance is increased to 142.5mm, ensure air clearance ＞ 125mm, outlet is connected with busbar is connect on the right side of busbar formula composite bushing, busbar is connected to overlap for naked T2 bus-types with busbar formula composite bushing junction, the busbar formula composite bushing right end with connect busbar lap-joint upper end and added half ring type isolation design, purpose is to reinforce phase insulation.The utility model, which designs, has good insulating, and the conformability of structure design advantages of simple and other accessories is good, has the advantages that extensive adaptability.
Description
Technical field
The utility model is related to the fields of casing, and in particular to a kind of busbar formula composite bushing.
Background technology
It is immersed in insulating gas on the left of conventional 202 composite bushings, is connected with conductor is connect；Right side by cable plug with into
Line cable connection.It is crosslinked polyetylene insulated, conventional 202 composite bushings because cable plug uses silastic material, inlet wire cable
Surface insulation with cable plug by silicon rubber ensures insulation performance, because of the insulation performance that silicon rubber is extremely strong, so using length
Insulation performance is can guarantee for the surface insulation of 90mm.Conventional composite bushing structure design is unreasonable, adaptability and poor reliability.
Busbar formula composite bushing is in the nonstandard scheme inflatable ring main unit, and one end is in insulating gas, and one end is in air
Busbar is connected, is usually used in metering cabinet or terminal incoming line cabinet.Unlike conventional 202 composite bushings, because one end exposes
In air, so wherein one end need to be made to increase creep distance design, the quarantine measures for making to reinforce phase insulation are also needed.
Utility model content
The purpose of the utility model is to overcome the shortcomings of the prior art, and provide a kind of busbar formula composite bushing.
The purpose of this utility model is completed by following technical solution：This busbar formula composite bushing, it is main to wrap
The shirt rim design on surface is included, is designed using lengthening creep distance on the right side of busbar formula composite bushing, ensures creepage distance ＞ 240mm, and add
Insulation clear distance has been grown to 142.5mm, ensures air clearance ＞ 125mm.
Outlet is connected with busbar is connect on the right side of the busbar formula composite bushing, and connection busbar is connect with busbar formula composite bushing
Place is that naked T2 bus-types overlap.
The busbar formula composite bushing right end with connect busbar lap-joint upper end and added half ring type isolation design, purpose
It is to reinforce phase insulation.
It is also to be immersed in insulating gas on the left of busbar formula composite bushing, so structure snd size and conventional 202 composite bushings
Identical, the utility model lower part can ensure phase insulation because busbar has heat-shrink tube supplementary insulation.
The beneficial effects of the utility model are：
1, the utility model has good insulating, and the conformability of structure design advantages of simple and other accessories is good, has wide
The advantages of general adaptability.

Specific implementation mode
Detailed introduction is done to the utility model below in conjunction with attached drawing：
As shown in the picture, this busbar formula composite bushing, the main shirt rim 61 including surface are designed, busbar formula composite bushing
6 right sides ensure creepage distance ＞ 240mm using creep distance design is lengthened, and increase insulation clear distance to 142.5mm, ensure air
Clear distance ＞ 125mm.
The 6 right side outlet of busbar formula composite bushing is connected with busbar 5 is connect, connection busbar 5 and busbar formula composite bushing 6
Junction overlaps for naked T2 bus-types.
6 right end of busbar formula composite bushing with connect 5 lap-joint upper end of busbar and added half ring type isolation design, mesh
Be to reinforce phase insulation.
It is also to be immersed in insulating gas on the left of 6 pipe of busbar formula compound sleeve, so structure snd size and conventional 202 composite bushings
1 is identical, and the utility model lower part can ensure phase insulation because busbar has heat-shrink tube supplementary insulation.
It is understood that it will be understood by those skilled in the art that the technical solution of the utility model and utility model structure
Think of, which is subject to equivalent substitution or change all, should belong to the protection domain of the utility model the attached claims.
