Description
Technical field
The present invention relates to structure of transmitting electricity, more particularly to a kind of high current power transmission and distribution all insulation cast transmission of electricity bus.
Background technology
At present, 35kv tube type bus use bare bus bar, the wrapped all-insulating tubular bus of filling type teflin tape, ternary
EP rubbers or the multi-layer co-extruded insulating tube type busbar of silicon rubber and poured with epoxy resin or the automatic class cast of gel process four of pressure
Bus.
Wherein, for bare bus bar, the transformer station of compact conformation to be particularly used in use, often meeting is alternate exhausted because bus
Edge is weak and there is single-phase earthing or phase fault accident, poor reliability and floor space is big.
For the wrapped all-insulating tubular bus of filling type teflin tape, due to using wrapped production, it is difficult to avoid layer
Between entrained air bubbles, cause teflin tape and the screen layer can not to be kept away along the moving of bus axis while teflin tape is smooth
Exempt from, thus product partial discharge be difficult to it is up to standard, with operation the time limit increase, the bubble or impurity being mingled with constantly discharge, around bubble
Dielectric constantly corrode, partial discharge level runs down, until flashover breakdown, the safe operation to power network brings greatly
It is dangerous.
For ethylene propylene diene rubber or the multi-layer co-extruded insulating tube type busbar of silicon rubber, Chinese patent CN104392801A (is awarded
Power date of publication is 2015.03.04) a kind of coextrusion insulated tube type bus of bright rubber multi-layer of ternary second are disclosed, this structure cannot
Realize that bend pipe structure is extruded, while the easy watered and wetting of shielding layer grounding line causes tube type bus inside salt face to climb electricity.Additionally, with mother
Comb is further added by one layer of protecting pipe and is difficult in adapt to the exceedingly odious outdoor environment such as salt fog high, peracidity as protective layer, difficult
To ensure the service life of 30 years.
For poured with epoxy resin or the automatic gel shaped tube type bus of pressure, using existing cylinder capacitive structure
Form, between insulating barrier set screen layer and ground plane, such as Chinese patent CN204215799A (authorize date of publication be
2015.03.18), there are problems that insulating materials and conductor material expand with heat and contract with cold it is inconsistent may cause insulating barrier be cracked, cause to split
Constantly discharged at seam, partial discharge level runs down, therefore possible partial discharge is exceeded at long conductor after in a few years running, and causes line
Road flashover.
Therefore, for drawbacks described above, existing technology need to be innovated.
The content of the invention
It is an object of the invention to provide a kind of 35kv all insulations enclosed busbar, by improving bus structure to reach reliability

A kind of 35kv all insulations enclosed busbar, including housing, contact tube, spring contact, disc insulator, supports insulative
Post, the housing is located at outermost, is cylindric pipe structure, for protecting installed in its internal high-pressure conductor not by any
Extraneous adverse circumstances influence, meanwhile, housing is imported in the middle of earth mat Arbitrary Fault electric current as the passage of earth-return circuit；Housing
On be provided with inflation valve device, can be to filling insulating gas in enclosure interior closed air chamber by inflation valve device；
The supports insulative post is integrally located at enclosure interior, and supports insulative post is fixed on shell by inserts bottom by rebound
The housing of body is pulled out at mouthful shrouding, for supporting contact tube；The insulated column center conductor and contact tube of supports insulative post internal package
Coaxially；Be conducive to electric fields uniform；Supports insulative post is internally provided with a spring and touches fat, makes contact tube and the same current potential of the insulated column；
Sealed by seal between supports insulative post and housing；
The disc insulator is fixed on inside the flange at housing two ends by metal insert, is not exposed in the middle of air,
Isolate with housing and the external world for contact tube, spring to be touched into fat, to reach the purpose of product all insulation；
Accordingly, the side that housing upper flange is contacted with disc insulator is provided with step, and the step is provided with bolt hole,
With fixing pot type insulator；
Described spring contact one end is fixed and is connected on the center conductor of disc insulator, and other end is with contact tube activity even
Connect, inside device has fairlead；
The contact tube is hollow-core construction for inside, is installed on enclosure interior, and is coaxial circles body with housing, conductive
Pipe is inserted in spring contact through insulated column center insert, and contact tube the selection of material can be copper tube or aluminum pipe；Preferably,
Using aluminum pipe；
