Description
Technical field
The present invention relates to a kind of water proof bus bar slot, belong to the technical field of transmission facility.
Background technology
Along with emerging in large numbers of modernization project facility and equipment, the fast increasing of power consumption of all trades and professions, the appearance in especially numerous skyscrapers and large-sized workshop workshop, can not meet the demands as in the present big current conveying system of traditional cable of transmission pressure, the parallel connection of multiway cable uses and brings inconvenience to in-site installation construction connection.Bus duct arises at the historic moment as a kind of new distribution wire.Traditional bus duct comprises housing, current－carrying conductor, current－carrying conductor is arranged in housing, in order to ensure the insulating properties of bus duct, spacing between adjacent current－carrying conductor is larger, insulation is realized by air, but larger heat can be produced in water proof bus bar slot running, easily by air breakdown, destroy the insulating properties between current－carrying conductor; In order to address this problem, the water proof bus bar slot of recent appearance, usually fill insulant or at current－carrying conductor outer cladding insulating barrier between current－carrying conductor, insulating material of the prior art or insulating barrier are generally ceramic coating or sulphurated siliastic layer, the water proof bus bar slot of this structure, although make the insulation property of bus increase, because the resistance to elevated temperatures of these insulating coatings is poor, the place that temperature is higher can not be used for.On the high temperature furnace of particularly Lian Gang factory or non-ferrous metal, the high temperature furnace temperature of general steel mill or non-ferrous metal is with at 2000 degree, and the temperature of operational environment is at about 180 degree; In addition, around the steam pipe line of petroleum chemical enterprise etc., temperature is very high; Therefore, the high temperature resistant requirement for bus is higher.
Summary of the invention
Technical problem to be solved by this invention is to provide that a kind of resistance to elevated temperatures is good, insulation property are strong and high temperature water proof bus bar slot under the hot environment of safety.
In order to solve the problems of the technologies described above, adopt following technical proposal:
A kind of high temperature water proof bus bar slot, comprise housing, some conductive carriers are provided with in described housing, wherein, described housing is integrated member, establishes Packed cavity in described housing, waterproof material is filled with in described cavity, described housing comprises upper cover plate, lower cover, is provided with and is respectively equipped with left and right side plate between described upper and lower cover plate, and described upper cover plate, lower cover, left plate and right plate are by one-body molded formation isosceles trapezoid component; Described conductive carrier is triangle disposition arrangement, and the described conductive carrier being positioned at top is arranged on described casing center line position; Insulator is filled with in described housing; Described conductive carrier is that cross section is curved, and the radian measure alpha of described conductive carrier is 70 °.
Above-mentioned high temperature water proof bus bar slot, wherein, the sidewall of described cavity is provided with insulating coating.
Above-mentioned high temperature water proof bus bar slot, wherein, described fire proofing material is alumina powder and magnesium oxide powder, described alumina powder: magnesium oxide powder is 1:2, and by weight, alumina powder particle diameter is 4 microns; Magnesium oxide powder particle diameter is 6 microns.
The beneficial effects of the utility model:
The utility model due to described housing be integrated member, Packed cavity is established in described housing, waterproof material is filled with in described cavity, described housing comprises upper cover plate, lower cover, be provided with between described upper and lower cover plate and be respectively equipped with left and right side plate, described upper cover plate, lower cover, left plate and right plate are by one-body molded formation isosceles trapezoid component; Described conductive carrier is triangle disposition arrangement, is filled with insulator in described housing; Described conductive carrier is that cross section is curved, and the radian measure alpha of described conductive carrier is 70 °, improves the heat conductivility of housing, and uses Shell Mechanics performance to be increased; In addition, the utility model by different-grain diameter filler distribution, filled up the hole of piling up between Large stone by small particle diameter, improve closely knit performance between material molecule, heat conductivility is improved greatly.
