Description
Technical field
The invention belongs to the buses of insulation tubes commutation technology, particularly a kind of buses of insulation tubes phase change method in generating, power transformation and distribution technique field.
Background technology
Buses of insulation tubes is power distribution equipment important in the transformer station of rising in recent years, plays an important role in electric power system.Be generally used for situation larger by total current in 35kV, 10kV electric power system.Application buses of insulation tubes, not only can improve the ampacity of conductor, can also solve the three-phase currents such as conventional flexible conductor, cable and to distribute unbalanced drawback.But, buses of insulation tubes also emerges the problem that some conventional wires do not have in application process, because conventional wires is generally steel reinforced aluminium conductor or cable, its two ends all have certain flexibility when being connected with transformer, switch cubicle, trend and layout can be changed, to ensure that wire is mutually corresponding with A, B, C three-phase of transformer, switch cubicle according to the flexible arrangement of transformer, switch cubicle.Because buses of insulation tubes belongs to hard conductor to a certain extent, just have problems in actual arrangement, as, when adopting inflatable switch cabinet when switch cubicle and arrange face-to-face in biserial in power distribution equipment indoor, because busbar arrangement in inflatable switch cabinet is certain, during towards gas-filling cabinet, its busbar arrangement is determined, i.e. A, B, C from left to right, can not exchange.Therefore, when gas-filling cabinet is arranged face-to-face, A, B, C three-phase of two row gas-filling cabinets is not one_to_one corresponding, and buses of insulation tubes come from main transformer side to be connected to gas-filling cabinet by master switch side, when one group of insulated tube mother that the mode of connection requires needs two branch, and two gas-filling cabinets corresponding to two branch are arranged face-to-face, time not on same row, namely go wrong.Be as the criterion if put in order with the bus of one of them gas-filling cabinet, then the bus erection sequence that buses of insulation tubes and opposite will inevitably be caused to arrange by total gas-filling cabinet is inconsistent.Therefore, the present invention proposes the buses of insulation tubes phase change method that a kind of practicality is stronger.
Summary of the invention
The object of the invention is to for the deficiencies in the prior art, a kind of buses of insulation tubes phase change method is provided.
The present invention solves its technical problem and takes following technical scheme to realize:
A kind of buses of insulation tubes phase change method, comprises step as follows:
(1) according to the layout of main transformer, inflatable switch cabinet, what formulation buses of insulation tubes laid moves towards arrangement;
(2) according to electrical connection situation, in the spatial dimension with commutation condition, commutation design is carried out; Concrete grammar is:
1. select A, above B, C three phase isolated pipe bus, there is the place being not less than 80cm space and carry out commutation design;
2. choose A, the A on side in B, C three phase isolated pipe bus, C two carries out commutation, and as shown in the figures 1 and 2, the concrete grammar of commutation is:
I, chooses A, the bending part that C buses of insulation tubes is determined separately everywhere, and every two bending part center position intervals are greater than 50cm;
II, by A, first bending part alignment of C two-phase buses of insulation tubes, by A, the exposed two insulated tube bus-bar ducts of C two-phase upwards bend with the obtuse angle of 135 degree of-150 degree, the second bending part is started after wherein a C phase upwards extends 40cm, with same angle recursion level direction, and the buses of insulation tubes direction of opposite side A phase is folded in the horizontal direction with the obtuse angle of 135 degree of-150 degree, when after the 3rd place's bending point that C phase buses of insulation tubes strides across above the arrival original position of opposite side A phase buses of insulation tubes, middle B phase top position, to turn back in the same way more original direction, be folded to below simultaneously, when C phase buses of insulation tubes extends downward the plan position approach of B phase buses of insulation tubes, namely during the point of bending everywhere, go back to again and B phase buses of insulation tubes arrangement position in the same way, adopt the mode same with C phase after four bendings, turn back to the opposite side of B phase buses of insulation tubes after wherein another root A phase buses of insulation tubes upwards extends 80cm,
III, outside all buses of insulation tubes conductors, wrap buses of insulation tubes screen, commutation is complete.
And the arrangement that moves towards that the bus of described step (1) lays specifically comprises: when having cable interlayer, utilize the cable bearer of cable interlayer, what make full use of existing cable bearer during layout moves towards layout, arranges independent suspension bracket when being necessary.
And, determine in the 1. step of described step (2) that the another kind of scheme in commutation space is, choose three phase isolated pipe bus upper and lower and respectively there is the place being not less than 40cm space carry out commutation design;
And, the concrete grammar of described another kind of commutation scheme is: wherein C phase buses of insulation tubes still keep up bending mode, upwards recursion level direction after extension 40cm, and finally get back to the opposite side of middle B phase buses of insulation tubes, the mode of bending is downwards selected in A phase buses of insulation tubes side, recursion level direction after downward-extension 40cm, and the opposite side finally getting back to middle B phase buses of insulation tubes.
And the knuckle angle of all bending parts is identical on described A, C two-phase buses of insulation tubes.
Advantage of the present invention and good effect are
1, the present invention proposes a kind of buses of insulation tubes phase change method, namely utilize the space of buses of insulation tubes to arrange trend, lay the design carrying out three-phase commutation in path process at buses of insulation tubes.After buses of insulation tubes inner wire is upwards bent certain angle along space by needs commutation place, then lay along former trend, then wrap the female screen of insulated tube, to realize commutation scheme at conductor skin.Thus ensure that the buses of insulation tubes of coming from transformer has A, B, C and C, B, A two kinds arranges characteristic, meet wiring requirement when arranging face-to-face by total inflatable switch cabinet biserial.
2, buses of insulation tubes phase change method of the present invention bends owing to adopting the angle of particular range, and therefore for the ampacity of buses of insulation tubes, heating and deformation are all guaranteed in the reasonable scope, do not affect the normal practicality of buses of insulation tubes.
