Along with China's rapid development of economy, the demand of entire society to electric power increases day by day.Current 110kV and 220KV electric substation low-pressure side all adopts 10kV, 35kV electric pressure, and along with the increasing of main transformer capacity, the rated current of step down side inlet wire side is also continuing to increase.Conventional rectangular bus technically with the more and more difficult requirement meeting bus heating and short-circuit electromotive force in structure, cause the increase of supplementary load loss, skin effect coefficient thus, cause the decline of the ability of damming, CURRENT DISTRIBUTION uneven.Especially separate unit main transformer capacity be 180MVA and above time, main transformer 10kV outgoing line side not only has electric power problem, the heating problem of bus bridge itself, also has the heating problem that the reinforcing bar near bus bridge post insulator, Steel Structure and bus bridge in coagulation upper prop, basis causes in elect magnetic field inductive loop.Insulation copper pipe bus is as the substitute of rectangular bus bar.It has following characteristics: ampacity is large: the main body of insulation copper pipe bus is hollow copper tubing or aluminium-alloy pipe, and surface area is large, relative conventional rectangular bus, and its conductive surface electric current distribution is even, and maximum amount determines electric current can reach 12000A.Good insulation preformance: insulation copper pipe bus adopts closed shield insulation mode, and earthing of casing current potential is zero, and bus surface electric field distribution is even, and electrical insulation properties is strong.Can directly by cable trough and cable interlayer.Mechanical strength is high: insulation copper pipe busbar body allowable stress is 4 times of rectangular bus bar, and the short circuit current that can bear is large, and mechanical strength is high, and bus is supported, and span is maximum reaches 8 meters.Good heat dissipation, temperature rise are low: insulation copper pipe bus is hollow conductor, and bus two ends have ventilation hole, and internal diameter air channel can self-assembling formation hot-air convection, and radiating condition is compared well conventional bus bar and will be got well.Loss is low: to determine its surperficial skin effect coefficient low for the profile of insulation copper pipe bus, and Kf≤1, AC resistance is little, and thus the power loss of bus is little.The dielectric loss of the insulating barrier of cross-linked shielding isolated bus is lower than 0.01%.Insulating material heat-resistance coefficient is high: the main insulation material of cross-linked shielding insulation tubular bus is polytetrafluoroethylene, there are excellent electric property and chemical stability, normally can work in-200 DEG C ~+200 DEG C, dielectric loss is little, fire-retardant, ageing-resistant, coordinate other insulating material, Shi Shou Ming≤30 year of product.Anti-electric vibration resistance is strong: Dynamic stability result of the test surface, and the copper pipe of voltage 10kV, rated current 4000A is female, can bear 63kA(4s) short-circuit current rush.Bus can directly be fixed on Steel Structure or on concrete support by it, cancels wall bushing and post insulator, has stronger shock resistance.Not by environmental interference, reliability is high: the every of insulation copper pipe bus is lock shield insulation mutually, innerly produces without condensation, and eliminates extraneous moisture, and dust and the ground connection caused by foreign object and phase fault, run and have reliability highly.Bus framework is simple and clear, it is clear, easy for installation to arrange, maintenance workload is few.
Traditional insulating tube type busbar production method is first by after glass fiber impregnated, then carries out vacuumizing process.By such method in the process of producing, easily there is micropore, can puncture, shortcomings such as being placed with impact of playing a game.
Therefore, for above-mentioned defect, first proposing the production technology of improvement, solving the problems referred to above by increasing by a heat-shrinkable T bush.And find in the process of producing, if time on direct lateral wall heat-shrinkable T bush being enclosed within conductor, in the process of infusion epoxy resin, easily occur the phenomenon that epoxy resin overflows from two ends, and the gas between heat-shrinkable T bush and conductor is not too easily discharged.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of epoxy resin that prevents and overflows and the insulating tube type busbar production method conductors dedicated of easy to exhaust.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of insulating tube type busbar production method conductors dedicated, and its innovative point is: comprise a conductor main body;
The lateral wall of described conductor main body is set with heat-shrinkable T bush, at the two ends of conductor main body, there is a spacing ring respectively, be respectively the spacing ring A being positioned at conductor main body left end and the spacing ring B being positioned at conductor main body right-hand member, spacing ring A has a greasing mouth be connected with the cavity between conductor main body and heat-shrinkable T bush, spacing ring B has an exhaust outlet be connected with the cavity between conductor main body and heat-shrinkable T bush, and the upper gas outlet of exhaust outlet is positioned at the upper end surface of spacing ring B.
Further, described spacing ring B has one end height of exhaust outlet higher than the height after filling epoxy resin between conductor main body and heat-shrinkable T bush.
The utility model has the advantage of: increase by a spacing ring respectively by the two ends at conductor main body, thus the phenomenon that epoxy resin overflows from two ends can well be avoided, set up greasing mouth convenient to injection ring epoxy resins in the cavity between conductor main body and heat-shrinkable T bush, set up exhaust outlet convenient by the air discharge in the cavity between conductor main body and heat-shrinkable T bush.
