Each tubular bus comprises a wire core which is successively wrapped in an insulated layer, a shielding layer, a heat-shrinkable sheath, and an insulated sheath. The wire core is in a regular octagonal shape and is provided with a plurality of heat-dissipating channels. A polytetrafluoroethylene layer wraps the wire core and is used as the insulated layer. The insulated layer is in a cylindrical shape and wrapped in the shielding layer in a regular decagonal shape. The shielding layer is an organosilicon flame-retardant heat-conducting silicone rubber insulating coating and is wrapped in the heat-shrinkable sheath in a cylindrical shape. The heat-shrinkable sheath is wrapped in the insulated sheath in a regular dodecagonal shape. The novel tubular bus system is good in toughness, insulating performance, and electrical performance.
Description
Technical field
The invention belongs to High-Voltage Electrical Appliances field, be specifically related to a kind of novel cast bus-bar system.
Background technology
Along with the development of domestic economy, the power load of each transformer station is surged thereupon, system running current is increasing, load is more and more concentrated, the main transformer capacity of transformer station is also increasing, and in the past in engineering more adopt the connected mode of multi-disc rectangle busbar or directly use cable connection, these well need not adapt to the working method of big current (more than 3000A), cause that supplementary load loss are large, CURRENT DISTRIBUTION is uneven simultaneously, skin effect coefficient increase cause current capacity to decline and the phenomenon such as contact heating more and more obvious.
Domestic bus, through technique improvement, makes insulating barrier mostly all adopt polytetrafluoroethylene to hold.The shortcoming of isolated bus is exactly mainly the middle insulation processing connected, the insulation of single pipe mother is all carry out before dispatching from the factory, transition joint is exactly for female the docking with single pipe mother of the single pipe in scene, the insulation processing of transition joint is done again after having docked, but the humidity of surrounding environment and temperature all can not meet, even manual hold time may bring impurity into, the electrical insulation properties of pipe mother is reduced greatly.
Summary of the invention
Technical problem to be solved by this invention provides a kind of New pipe for above drawback
typebus-bar system, good toughness, good insulation preformance, good electric property.
For solving the problems of the technologies described above, technical scheme of the present invention is:
One novel cast bus-bar system, comprise tube type bus and syndeton, adjacent tube type bus is fixedly connected with by syndeton, described tube type bus comprises core, the outer coated insulation layer successively of core, screen, sheath shrinkable sleeve and insulating sleeve, described core is octagon structure, some heat dissipation channels are provided with in core, described core outer cladding one deck polytetrafluoroethylene is as insulating barrier, described insulating barrier is cylindrical structural, the screen of insulating barrier outer cladding one deck regualr decagon, described screen is organic silicon flame-retardant heat-conducting silicon rubber insulating coating, the sheath shrinkable sleeve of described screen outer cladding one deck cylindrical structural, the insulating sleeve of described sheath shrinkable sleeve outer cladding one deck dodecagon,
Described connecting elements, comprise connecting elements main body, described connecting elements main body is the cylindrical structural of hollow, metallic conductor is provided with in connecting elements main body, metallic conductor will be divided into two bus lock chambers in connecting elements main body, the chamber wall progressive additive from inside to outside of described bus lock chamber, make tapered structure in bus lock chamber, described metallic conductor two ends are respectively provided with a splicing ear, described connecting elements main body is axially arranged with some pressing grooves, and connecting elements main body two ends engage a stainless steel annulus for sealing respectively.
Above-mentioned novel cast bus-bar system, wherein, described insulating sleeve forms by silastic elastomer is high temperature vulcanized.
Above-mentioned novel cast bus-bar system, wherein, the thickness of described insulating barrier, screen, sheath shrinkable sleeve and insulating sleeve successively decreases successively.
Beneficial effect of the present invention is:
Buses of insulation tubes is hollow conductor, and surface area is large, and conductive surface electric current distribution is even.Therefore, isolated bus is particularly suitable for the large loop of operating current.
The allowable stress of buses of insulation tubes is 4 times of rectangular bus bar, and the short circuit current that can bear is large, and mechanical strength is high, makes bus support span and strengthens.When 50KA short circuit current, the unsettled span of Φ 100 × 5mm isolated bus reaches 9 meters, bus bar cupport is utilized to support, the span of bus can reach 13 meters, because bus span is large, directly can enter hyperbaric chamber to be connected with indoor current limiting reactor or 10 KV switch cabinets, decrease corresponding post insulator, bus gold utensil and civil engineering framework basis.
Buses of insulation tubes adopts closed shield insulation mode, and earthing of casing current potential is zero, because electric shield has: a. makes Electric Field Distribution even; B. controlling potential and restriction electric field; C. avoid producing partial discharge at insulating surface; D. conduct leakage current and charging current; E. carry out the characteristic such as protecting to the touch voltage of danger, therefore the insulation tubular bus Electric Field Distribution of this band shielding is even, electrical insulation properties is strong.
Structure of the present invention is simple, easy for installation, only need in insertion bus lock chamber relative for tube type bus, splicing ear on metallic conductor is directly contacted with the core of tube type bus, and mechanical strength is high, is connected and more fits between conductor with connector, conduct electricity very well, in use can effectively avoid causing damage to bus, more safe and reliable, add useful life.
