Description
Technical field
The utility model relates to a kind of pipe bus, belongs to T & D Technology field.
Background technology
Development along with domestic economy, the power load of each transformer station is surged thereupon, system running current is increasing, load more and more concentrated, the main transformer capacity of transformer station is also increasing, and in engineering, adopted the connected mode of multi-disc rectangle busbars more or directly used cable to connect in the past, these need not well adapt to the working method of large electric current (more than 3000A), cause that supplementary load loss are large, CURRENT DISTRIBUTION is uneven, skin effect coefficient increases phenomenons such as causing current capacity decline and contact heating more and more obvious simultaneously.
Domestic bus, through technique improvement, makes insulating barrier mostly all adopt polytetrafluoroethylene to hold.The insulation processing that the shortcoming of isolated bus connects in the middle of being exactly mainly, single pipe mother's insulation is all to carry out before dispatching from the factory, transition joint be exactly for the single pipe in scene female with the docking of single pipe mother, after having docked, do again the insulation processing of transition joint, but the humidity of surrounding environment and temperature all can not meet, even manual hold time may bring impurity into, make to manage female electrical insulation properties and greatly reduce.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of pipe bus for above drawback, can under awful weather condition, move, be widely used in power plant, power station, electric substation, photovoltaic plant, wind power generation transformer station, be one of power transmission and transformation transmission visual plant, solve electric field problem of non-uniform, improve bus surface mechanical strength.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of pipe bus; comprise pipe bus main body; wherein; described pipe bus main body is built one deck epoxy resin main insulating layer outward, in described epoxy resin main insulating layer, is filled with nano imvite particle, and described nano imvite particle is oval hollow bead; its surface uniform is provided with some through holes; described epoxy resin main insulating layer is coated the first metal screen layer, separator, the second metal screen layer and protective layer outward successively.
Above-mentioned a kind of pipe bus, wherein, described pipe bus main body two ends are provided with stress cone, in described stress cone, are filled with nano imvite.
The beneficial effects of the utility model are:
In epoxy resin, be filled with nano imvite, improve bus operational reliability, meet dynamic and thermal effect, reduction office puts, and production cost is low, is more suitable for large-scale production, the loss of bus insulation material medium is little, safe and reliable, long service life in service, improves bus junction surface corona voltage, reduces junction surface field intensity.
Adopt Bimetallic shielding and one deck separator, insulating material adopts filling nano organic montmorillonite in epoxy resin, by the optimization to nano organic montmorillonite content, interface interaction, dispersity, can make the mechanical energy of material be greatly enhanced, on block-water performance, be all improved, naturally also can improve its hydrothermal aging performance, naturally also can improve ageing-resistant performance under its illumination.By epoxy resin, insert organic montmorillonite layer and react at interlayer, make lamella expand, dissociate, final formation dissociated or the nano composite material of intercalation.Be applicable to indoor outside, reduce electric radiation magnetic wave, reducing electromagnetic pollution, to make it be minimum, avoids or eliminate electromagnetic radiation to human health damage, preserves the ecological environment.Improve easy for installation, contact resistance is little, good heat dissipation, meet that large electric current is carried, moving and thermal stability is high.While having solved bus operation by the variation of temperature, cause that bus axial dimension changes to be compensated, this is the not enough problem that overcomes background technology.
