Description
Technical field
The present invention relates to a kind of bus duct of intensity, more particularly, the present invention relates to bus duct a kind of intensity, that be used to carry mesohigh electric power.
Background technology
Develop rapidly along with the city, skyscraper is more and more, the building power load sharply increases thereupon, and original electric wire is because its capacity is little, branch is inconvenient, be not easy to reason such as boundling management, and is progressively big by capacity, branch convenient, boundling manages easily that bus duct replaces.Bus duct is widely used in key projects such as the electric power conveying route of fire-fighting fire fighting service and fire-fighting emergent equipment main line, for example be used for important engineerings such as hotel, airport, subway, so the safety and stability performance of bus duct product is most important.
But bus duct also exists some shortcomings, such as, because arranging, the boundling between the bus duct can produce bigger heat usually, the heat dissipation problem of bus duct also is a hang-up that all the time perplexs the bus duct research staff.Particularly for the mesohigh bus duct, because this type of bus duct mainly is the electrical power mains line of mesohigh, so heat-sinking capability, security performance and whether effectively to reduce electric energy loss be vital.If such mesohigh bus duct does not possess necessary heat dispersion,, just bring fire safety hidden danger probably in case the high temperature that the connection busbar in the bus duct is produced can not in time leave.
Mesohigh bus duct in the market is divided into common box type, it is box to divide, copper pipe formula or the like.But the said goods all exists the structure heat-sinking capability poor, and the copper resource cost is big, and temperature rise and electric energy loss are big, poor safety performance, and defective such as short-circuit strength is low, and bulky, external form is not attractive in appearance.
China's utility model patent discloses a kind of high pressure enclosed busbar groove for No. 94203181.4, comprise housing, be arranged in the housing one group of parallel electric conductor and in order to clamping, fixedly the insulation holder and the Jia Gai of electric conductor, the bottom of insulation holder and folder lid has corresponding through hole, in order to make by bolt on its madial wall that is fixed on housing; Electric conductor is coated by irradiation interlinkage ethylene-propylene polymer sleeve pipe, and electric conductor adopts the socket connection termination.
China's utility model patent discloses a kind of low pressure enclosed busbar groove for No. 02218490.2, its cover plate and side plate are made of special flute profile aluminium alloy extrusions, lateral surface vertically sets up 2-4 root reinforcement at the bottom of slot cover, be big flute profile in the middle of the side plate cross section, two is little flute profile, and two sulculus shape notches and big flute profile notch towards opposite.The phase isolation block of bus duct is made of resistant to elevated temperatures Merlon, and phase isolation block is for pegging graft in opposite directions in twos up and down, and the every rectangular hollow form of phase isolation block, its top front and back sides are provided with corrugation shape eyebrow curtain.
Yet above-mentioned prior art all exists heat-sinking capability poor, and the copper resource cost is big, and electric energy loss is big, and the problem that security performance is relatively poor can't satisfy the requirement of mesohigh transmission line.
Therefore, provide the concentration bus duct that a kind of thermal diffusivity is strong, electric energy loss is little and security performance is high to become the problem that industry need solve.
Summary of the invention
