Description
Technical field
The invention belongs to field of electrical equipment, relate to a kind of totally-enclosed fire resistant flame retardant bus of big electric current in using in generating, in the power transmitting device specifically.
Background technology
Bus refers to that copper, the aluminum material with high conductivity process, and in order to electric energy transmitting, has the product that compiles with electrical power distribution.Usually in the power station or total lead of using of transformer station's transmission of electric energy be bus structure.Can give each user or other electric substations with the power delivery of generator, transformer or rectifier output through it.The bus structure of prior art usually with conductive strips be fixed on bus poor in, realize connecting through bus duct, because therefore not sealing of bus duct is easy to cause the generation of short circuit current fault even cause casualties.As a kind of improvement of bus technology, closed bus technology develops gradually, maturation.Closed bus is made up of current, housing and insulating sleeve material usually, and the bus housing adopts the high-quality cold-rolled steel sheet to process usually, has enough mechanical strengths, degree of protection; Current adopts the electrician meet the GB5585.1-5585.3 standard to carry out special processing with the contact-making surface of copper product, conductor contact and makes the connecting portion contact reliably; It is low to generate heat; Safe and reliable, insulating material has a performance index such as good insulation preformance, anti-aging, nontoxic, low cigarette.
Enclosed busbar is divided into two kinds of forms according to its purposes, and a kind of enclosed busbar ampacity is big, but non-refractory can only work under 200 ℃ of temperature, is installed in usually on the circuit of carrying civil power, and this kind bus also is the intensive enclosed busbar; Another kind of enclosed busbar can be high temperature resistant, generally under the condition of 700～1000 ℃ of ambient temperatures, can keep 1.5 hours transmission operation, and its ampacity maximum can reach 5000A, and this kind enclosed busbar is fire-resistant enclosed busbar.But owing to scribble one deck fireproof coating on the housing of fire-resistant enclosed busbar, and intensive enclosed busbar surface plastic spraying, smooth, anticorrosive coat strong adhesion.Therefore, when fire-fighting circuit and emergency power supply line design employing bus, all adopt fire-resistant enclosed busbar.Fire-resistant enclosed busbar needs bigger space, the inconvenience of turning round when mounted.Traditional fire-resistant closed bus owing to scribble fireproof coating, causes cost higher, and adopts the spraying coating process more complicated, causes the inhomogeneous faults such as high-voltage breakdown that cause of spraying easily; In addition, the greatest drawback of traditional bus is, can not arbitrarily change shape according to environment for use.
Summary of the invention
The objective of the invention is to propose a kind of totally-enclosed fire resistant flame retardant bus by new structure in order to solve the above-mentioned defective of existing closed bus, it has totally enclosed insulation, fire performance, and can bend according to environment for use.
Realize that above-mentioned purpose technical scheme of the present invention does; A kind of totally-enclosed fire resistant flame retardant bus comprises insulating coating, steel band and conductive strips; Wrap up mica tape on the conductive strips; Fill insulating barrier between the adjacent conductive band, the high flame retardant glass tape will be twined by steel band after will being filled with the whole parcel of conductive strips of insulating barrier again, and insulating coating covers the outermost layer of bus.Insulating coating adopts polyvinyl chloride, crosslinked polyethylene, electro-insulating rubber, synthetic resin, silicon rubber, fluoroplastics, the fine compound of fourth or mineral insulating material.The material of filling insulating barrier between the adjacent conductive band can adopt and the insulating coating identical materials.
Conductor strip is by the range upon range of structure of forming of high conductivity metal sheet.
The busbar cross-section profile is a rectangle, and the conductive strips quantity in the bus is 4 and becomes 3 phase 4 line structures or 5 one-tenth 3 phases 5 line structures.The insulating barrier of filling between the adjacent conductive band is through the pouring type moulding.
The advantage that technical scheme of the present invention has comprises: (1) adopts mica tape parcel conductive strips structure more to strengthen fire resistance; (2) high flame retardant glass tape and steel band all are arbitrarily to change the structure of shape, thereby have realized the shape of generatrix flexibility and changeability; (3) insulating coating and high flame retardant glass tape are refractory material, have realized fire-resistant, the anti-flaming function of bus; (4) conductor strip is the range upon range of structure that forms of multilayer high conductivity metal sheet, thus conductor strip more soft, curve.

Fig. 1 is a totally-enclosed fire resistant flame retardant bus sectional structure chart according to the invention;
Among the figure 1, insulating coating; 2, steel band; 3, high flame retardant glass tape; 4, conductive strips; 5, mica tape; 6, insulating barrier.
Embodiment
Specifically describe in the face of technical scheme of the present invention down; Fig. 1 is a totally-enclosed fire resistant flame retardant bus sectional structure chart according to the invention; As shown in the figure; Utilize the conductive strips 4 of multilayer high conductivity metal sheet through range upon range of making, between 0.1～1mm, material selects copper sheet or aluminium strip etc. to have the material of good cold draw property to the sheet thicknesses of range upon range of making conductive strips usually usually.The conductor strip of making like this has softness, bent characteristic, has improved the flexibility ratio of bus.
Conductor strip can significantly improve the fire-resistance property of conductive strips with mica tape 5 parcel, promptly externally under the situation of environment breaking out of fire, plays the mica fire retardation.Between the adjacent conductive band, fill insulating barrier through pouring type; The material that cast forms insulating barrier is polyvinyl chloride, crosslinked polyethylene, electro-insulating rubber, synthetic resin, silicon rubber, fluoroplastics, the fine compound of fourth or mineral insulating material; These materials not only have insulating effect; And all be exotic material, under the situation of conductive strips, can not form short trouble owing to the material sex change causes the insulation effect variation through big electric current heating.For insulating requirements is satisfied in the flexibility that increases bus simultaneously; At cast cured explosive parcel high flame retardant glass tape 3 on the conductive strips of insulating barrier; On the high flame retardant glass tape, be enclosed with steel band 2 to strengthen the intensity of bus; Outside steel band, be with insulating coating 1, make the material of insulating coating and can select for use and the insulating barrier identical materials.Bus be shaped as rectangle so that bend more flexibly.The number of conductor strip can select 4 to become 3 phase 4 line structures or 5 one-tenth 3 phases 5 line structures according to actual needs.
Technique scheme has only embodied the optimal technical scheme of technical scheme of the present invention, the technical staff in present technique field to some part wherein some changes that possibly make all embodied principle of the present invention, belong within protection scope of the present invention.
