Abstract
The invention relates to a phase change method of insulating tube buses. The phase change method of the insulating tube buses comprises the steps that (1) a run layout plan of the insulating tube buses to be laid is made according to the layout of a main transformer and inflatable switch cabinets, and (2) according to electric connection situations, a phase change design is carried out in a space range meeting phase change requirements, wherein phase change design is carried out in a space not less than 80cm above three-phase insulating tube buses A, B and C, and the sideward three-phase insulating tube buses A and C are selected from the three-phase insulating tube buses A, B and C to carry out phase change. The phase change method of the insulating tube buses meets the wiring requirements when two rows of the inflatable switch cabinets are arranged face to face, due to the fact that the insulating tube buses are bent at an angle in a specific range, it is ensured that the carrying capacity, heating and deformation of the insulating tube buses are in a reasonable range, and normal use of the insulating tube buses is not affected.
Description
Technical field
The invention belongs to the buses of insulation tubes commutation technology in generating, power transformation and distribution technique field, particularly a kind of buses of insulation tubes phase change method.
Background technology
Buses of insulation tubes is power distribution equipment important in the transformer station of rising in recent years, in electric power system, plays an important role.Be generally used for being subject to the situation that total current is larger 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, the cable unbalanced drawback that distributes.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, can change trend and layout according to the flexible arrangement of transformer, switch cubicle, mutually corresponding to guarantee A, B, the C three-phase of wire and transformer, switch cubicle.Because buses of insulation tubes belongs to hard conductor to a certain extent, in actual arrangement, just have problems, as, when switch cubicle adopts inflatable switch cabinet and power distribution equipment is indoor when being biserial and arranging face-to-face, because busbar arrangement in inflatable switch cabinet is certain, during towards gas-filling cabinet, its busbar arrangement is determined, A, B, C from left to right, can not change.Therefore, when gas-filling cabinet is arranged face-to-face, the A of two row gas-filling cabinets, B, C three-phase are not corresponding one by one, and buses of insulation tubes from main transformer side, come to be connected to gas-filling cabinet be subject to master switch side, in the mode of connection, require the female pair branches that need of one group of insulated tube that come, two gas-filling cabinets corresponding to Qie Shuan branch are arranged face-to-face,, when same listing, do not go wrong.If put in order and be as the criterion with the bus of one of them gas-filling cabinet, will inevitably cause buses of insulation tubes and opposite row to be subject to the bus erection sequence of total gas-filling cabinet 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 phase change method, comprises that step is as follows:
(1), according to the layout of main transformer, inflatable switch cabinet, formulate the arrangement that moves towards that buses of insulation tubes lays;
(2), according to electrical connection situation, in the spatial dimension with commutation condition, carry out commutation design; Concrete grammar is:
1. select A, B, C three phase isolated pipe bus top has the place that is not less than 80cm space and carries out commutation design;
2. choose A, B, the A on side in C three phase isolated pipe bus, two of C carry out commutation, and as shown in Fig. 1 or 2, the concrete grammar of commutation is:
I, chooses A, definite bending part everywhere separately on C buses of insulation tubes, and every two bending part center position intervals are greater than 50cm;
II, by A, the first fold crook alignment of C two-phase buses of insulation tubes, by A, the upwards bending of obtuse angle that two exposed insulated tube bus-bar ducts of C two-phase are spent with 135 degree-150, wherein a C starts the second bending part after extending upward mutually 40cm, with the same angle horizontal direction of turning back, and with the obtuse angle of 135 degree-150 degree, be folded in the horizontal direction the buses of insulation tubes direction of opposite side A phase, in the middle of C phase buses of insulation tubes strides across, B phase top position arrives after the 3rd place's bending point of top, the original position of opposite side A phase buses of insulation tubes, original direction of turning back in the same way again, 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 everywhere during bending point, go back to again and B phase buses of insulation tubes arrangement position in the same way, wherein another root A phase buses of insulation tubes adopts the mode mutually same with C after four bendings, to turn back to the opposite side of B phase buses of insulation tubes after extending upward 80cm,
III, wraps buses of insulation tubes screen in all buses of insulation tubes conductors outside, and commutation is complete.
And the arrangement that moves towards that the bus of described step (1) lays specifically comprises: while having cable interlayer, utilize the cable bearer of cable interlayer, make full use of the layout of moving towards of existing cable bearer during layout, independent suspension bracket is set while being necessary.
And, in the 1. step of described step (2), determine 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 that is not less than 40cm space and carry out commutation design;
And, the concrete grammar of described another kind of commutation scheme is: the mode that wherein C phase buses of insulation tubes still keeps up and bends, extend upward the horizontal direction of turning back after 40cm, and the opposite side of B phase buses of insulation tubes in the middle of finally getting back to, A phase buses of insulation tubes side is selected the mode of bending downwards, to the horizontal direction of turning back after downward-extension 40cm, and the opposite side of B phase buses of insulation tubes in the middle of finally getting back to.
And, described A, on C two-phase buses of insulation tubes, the knuckle angle of all bending parts is identical.
Advantage of the present invention and good effect are
1, the present invention proposes a kind of buses of insulation tubes phase change method, utilize the space of buses of insulation tubes to arrange trend, at buses of insulation tubes, lay the design of carrying out three-phase commutation in the process of path.In needs commutation place, buses of insulation tubes inner wire is upwards bent after certain angle along space, then lay along former trend, then wrap the female screen of insulated tube at conductor skin, to realize commutation scheme.Thereby guaranteed that the buses of insulation tubes of coming from transformer has A, B, C and C, B, two kinds of layout characteristics of A, meets wiring requirement while arranged face-to-face by total inflatable switch cabinet biserial.
2, buses of insulation tubes phase change method of the present invention is owing to adopting the angle of particular range to bend, 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.
