Description
Technical field
The utility model belongs to the power transmission and distribution technical field, relates in particular to the special-purpose section that bus duct is used in a kind of low voltage power transmission.
Background technology
Low-voltage intensive bus duct mainly carries power delivery task of low pressure, is widely used in the nominal insulation voltage of transformer station, industrial enterprise, engineering construction less than the once transmission of electricity place of 1000v, belongs to flexible for installation, uses low-voltage bus bar extremely widely; Arrangement is flexible: along the floor plan of heavy construction surrounding, being arranged vertically of floor gap arranged other all possible layout between the cabinet between transformer and power distribution cabinet, between power distribution cabinet and power distribution cabinet; Due to the heavy construction space is large, story height, various pipeline in length and breadth, transmission facility walks the network complexity, require high to bus duct version, particularly large span product, in use exist distortion, heat radiation, corona and power frequency vibrations and device start impact endurance test shock; Compare with traditional bus duct, Novel bus duct must possess higher integral rigidity, good anti-seismic performance and heat dispersion.
Section bar is the critical piece of intensive low voltage power transmission bus duct equipment.Low voltage bus bar groove is important transmission facility, and it forms a closed transmitting loop by housing and conductor, completes the power delivery of transmission of electricity primary circuit; Bus groove case is formed by section bar and side plate riveted joint, the bus duct section bar not only plays rigidity support, fixation, or the positioning supports of main bus bar system, degree of protection ensures, therefore the quality of its version, rigidity size, mechanical performance and Electric Field Distribution is directly connected to the ability that current capacity, heat dispersion, non-deformability, fail safe and the fault-resistant of a transmission facility operation destroy.
At present, intensive low-voltage bus bar channel section kind popular on market is a lot, and material has iron-based, aluminium base dividing, and there are the defectives such as eddy current, magnetic hysteresis heating in iron, and is not recommended.Popular aluminium base section bar mainly contains three kinds of versions: the first be traditional concentration bus duct without the single limit H section bar of hanging in location, advantage be quality light, economize material, shortcoming is the section bar insufficient rigidity, cause the housing integral rigidity poor, connect unreliable; Without Position Design, can't guarantee assembly precision.The second is the single limit H section bar of hanging in location of the concentration bus duct of improvement, compares with the first section bar, and section bar rigidity makes moderate progress, and Position Design can guarantee the whole assembly precision of bus duct; But for the above lengthy product of 4m, the housing integral rigidity is still not enough.The third is the single limit heat radiation H section bar of hanging in location of follow-on concentration bus duct, compare with front two kinds of section bars, the heat dispersion of product has obtained certain improvement, shortcoming is that section bar rigidity is still not enough, can't satisfy the rigidity requirement of the above large scale product of 4m, very easily cause deformation of products, connect unreliablely, have potential safety hazard.
The utility model content
For above-mentioned technical problem, the utility model provides the special-purpose section of the good bus duct of a kind of Rigid Large-span Steel.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is that a kind of bus duct special-purpose section comprises web and the wing plate that is positioned at the web two ends, described wing plate employing opening E type structure to the inside.
The utility model special-purpose section, two ends at slabbing web, adopt the wing plate of E type structure, be that end right cylinder and up and down twice level are hung the limit combining structure, improved to greatest extent the integral rigidity of section bar, thereby improve the bus duct integral rigidity, the electric energy bearing capacity of whole bus duct system is got a promotion; Simultaneously, guarantee the rigidity requirement of the above large span bus duct of 6m, reduce conductor and connect, reduce operation risk, reduce the customer investment cost.
Further improve as the utility model, described web one side is provided with protruding rib body, to increase the heat-delivery surface of special-purpose section, has further increased the rigidity of section bar simultaneously; The another side is provided with opening to the L-type positioning bar at web middle part, quick location in place and accurate when facilitating the bus duct integral installation.
