Description
(1) technical field
The utility model relates to a kind of new-type branch mailbox GIS case main bus structure altogether, belongs to SF
6a part for Cubicle Gas-Insulated Switchgear.
(2) backgroundtechnology
Present stage, 110kV SF
6cubicle Gas-Insulated Switchgear divides box structure progressively to step down from the stage of history, altogether box structure progressively comes into vogue because of plurality of advantages such as its floor space is little, working service cost is low, compact conformation, good looking appearance, security reliability height, but more domestic provinces, more external client are still higher for separate-box type high voltage switchgear degree of recognition, and market demand is still very large.In 252kV and above equipment, because the restriction of the factors such as it is cut-off, insulation, maintenance still relies on separate-box type structure at present, separate-box type high voltage switchgear remains the developing direction of high voltage switchgear, has higher economic worth and market value.Separate-box type high-voltage combined electrical apparatus equipment is through technological improvement, current technology are relatively ripe several times, stabilization of equipment performance, fail safe obtain users' generally accreditation, be subject to the restriction of its structure, at present separate-box type high voltage switchgear together box type high-voltage switchgear compare exist cost high, install and use process complexity, the relatively large shortcoming of floor space.This technology is intended to optimize separate-box type GIS case main bus structure, simplification installation process, the equipment Installation Flexibility that improves altogether, and enhancing safe and stable equipment operation, has effectively solved a series of problem existing in separate-box type high-voltage switch gear structure.
(3) utility modelcontent
The utility model, for making up the deficiencies in the prior art, provides a kind of new-type branch mailbox GIS simple in structure, stable and reliable for performance, that be convenient to install to be total to case main bus structure.
The utility model is achieved by the following technical solution:
New-type branch mailbox GIS of the present utility model is case main bus structure altogether, comprise bus housing, it is characterized in that: also comprise three disc insulators that are arranged on bus housing, and be arranged on the three-phase bus conductor in bus housing, touch base, Mume flower contact, main bus conductor, three-phase bus conductor upper end is bolted separately on disc insulator, disc insulator is kept apart main bus bar air chamber and interval body air chamber, three-phase bus conductor lower end connects touch base, touch base one side is installed Mume flower contact, Mume flower contact connects main bus conductor, touch base opposite side selectivity is installed Mume flower contact or end cap.
Shading ring is installed in contact site between bus-bars conductor and disc insulator, to prevent contact portion point discharge, plays the homogenizing effect of Electric Field Distribution around.
The outside guide ring of installing of Mume flower contact, increases the effective contact area of connecting portion when main bus conductor is contacted with Mume flower contact.Guide ring contacts with touch base.
The beneficial effects of the utility model are, the advantages such as simple in structure, good looking appearance, cost are low, safe and reliable, highly versatile, this structure cost-saving 30% compared with traditional structure, save labour nearly 40%, simplify installation and maintenance process, there is high cost performance, be highly suitable for unattended operation transformer station operation.Perforate on housing before having changed, insulating cylinder support labyrinth fixing, air seal, have avoided the harm such as insulation breakdown, gas leakage.This connection can be widely used in separate-box type 126kV high-voltage combined electrical apparatus and 252kV separate-box type high-voltage combined electrical apparatus equipment, uses flexibility high, and it is very convenient to install.
(4) brief description of the drawings
Fig. 1-4 are followed successively by front view, left view, the A-A cutaway view of original main bus structure, the schematic diagram of C-C cutaway view.Fig. 5,6 is followed successively by front view of the present utility model, left view schematic diagram.
In figure, 1-bus housing, 2-shading ring, 3-B phase bus-bars conductor, 4-A, C phase bus-bars conductor, 5-main bus conductor, 6-Mume flower contact, 8-touch base, 9-end cap, 10-bolt, 11-hand hole cover plate, 12-insulating supporting, 13-insulator.
(5) embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.
New-type branch mailbox GIS of the present utility model is case main bus structure altogether, comprise bus housing 1, also comprise three disc insulators 13 that are arranged on bus housing, and be arranged on the A phase bus-bars conductor 4 in bus housing, B phase bus-bars conductor 3, C phase bus-bars conductor 4, touch base 8, Mume flower contact 6, main bus conductor 5, three-phase bus conductor upper end is bolted separately on disc insulator, shading ring 2 is installed in contact site between bus-bars conductor and disc insulator, to prevent contact portion point discharge, play the homogenizing effect of Electric Field Distribution around, three-phase bus conductor lower end connects touch base 8, touch base one side is installed Mume flower contact 6, cancel original structure insulating supporting part, cost 30% saves material, simplify main bus bar Installation and Debugging process, save labor cost nearly 40%.Mume flower contact connects main bus conductor 5, and the outside guide ring of installing of Mume flower contact, obtains more balanced stress distribution when main bus conductor is contacted with Mume flower contact, increase the effective contact area of connecting portion, reduce contact resistance, reduce equipment temperature rise, improve safe and stable equipment operation.Touch base opposite side can selectivity be installed Mume flower contact or end cap 9, can realize the two-way or unidirectional connection of main bus bar, and main bus bar Installation Flexibility is improved significantly.Three-phase bus conductor dbus is crossed touch base, Mume flower contact is connected with other structures, forms galvanic circle.This utility model reduces sealing surface 3 places compared with original structure, effectively reduce the Leakage Gas phenomenon that equipment too much causes because of hermetically-sealed construction, in addition the use of disc insulator can make main bus bar air chamber and interval body air chamber keep apart, the processing time of gas while having simplified main bus bar fault, transmission of electricity quality obtains stronger guarantee, and advantage is particularly remarkable.
This structure is installed the support of exempting from of bus-bars conductor by changing the realization of bus-bars conductor structure, Installation Flexibility improves greatly, three-phase bus conductor is bolted on insulator, by the further homogenizing conductor of radome Electric Field Distribution around, reduction equipment office discharges water flat, improves equipment safety in operation.
This structure can be improved plum blossom fingertip stress distribution effectively by the Self-centering Action of guide ring, increases the obvolvent degree of fingertip and conductor, reduces contact resistance and equipment temperature rise.
