Description
Technical field
The present invention is a kind of waterproof bus mains system that is used for big electric current power and distribution supply cable, belongs to the technical field that automatically controlled controller switching equipment is made.
Background technology
Bus mains system (abbreviation bus duct) is extensive use of in the power and distribution supply cable engineering of China, product structure has air insulation type, intensive insulated type, fire safe type, water proof type, more than except that the water proof type bus has the performance of waterproof or immersion, the performance that other do not have waterproof does not especially have the performance of corrosion resistant.Need waterproof and corrosion resistant special operation condition environment for use in order to be applicable to, domestic have a lot of manufacturing enterprises to develop totally-enclosed composite resin material pouring bus groove in succession, and this waterproof bus has following shortcoming in actual use:
1, the water resistance of individual event has reached instructions for use substantially, but because the ampacity of bus-bars conductor is bigger, the solid insulating material thermal resistance of cast is big, and is cast between phase and phase together, and area of dissipation is little, be unfavorable for distributing of conductor heat, the heat radiation difficulty has become the defective of this product maximum, for guaranteeing the safety of bus transmission of electricity process, the calculating of cross-sectional area of conductor, generally will be higher than more than 30% of common bus-bars conductor, so its cost is high;
2, integrated poured bus is limited to structure, when overall length surpasses 40 meters, there is the insurmountable expansion problem of stretching, the stress that produces when variations in temperature concentrates on local when a bit, cause product cracking, insulating barrier destroyed, cause serious potential safety hazard, even short circuit occurs, blow out phenomenon, make the paralysis of whole supply line and be difficult to recover;
3, the drawback of integrated poured bus maximum is non-dismountable property, in case bus breaks down, can't check and be out of order a little, can not thoroughly recover the function of product, and the power supply that has a strong impact on circuit is used;
4, integrated poured bus insulation layer and conductor closely link together, be difficult to dismounting, because what insulating barrier adopted is that thermoset macromolecule material can't be degraded, so on the conductor metal MAT'L recycling, have problems from now on, this problem does not solve, and will bring the waste of a large amount of metal material resources and the pollution of environment.
Technology contents
Goal of the invention: goal of the invention of the present invention provides a kind of high-performance, low cost, corrosion-resistant, airtight water-tolerant, easy heat radiation, safe and reliable, removable phase-splitting insulation combined water proof bus bar slot.
Technical scheme: phase-splitting insulation combined water proof bus bar slot of the present invention comprises insulating sleeve shell, connection spacer block and connecting bolt, metallic conductor row; In the abdominal cavity of metallic conductor ranking in the insulating sleeve shell, connect spacer block between two insulating sleeve shells, connecting bolt pass the insulating sleeve shell be connected spacer block with the insulating sleeve shell be connected spacer block and connect into an integral body.Described connection spacer block can divide some compositions along the length direction of insulating sleeve shell.Connect spacer block and can divide two compositions along insulating sleeve cross-sectional outer direction.
Beneficial effect: phase-splitting insulation combined water proof bus mains system of the present invention is owing to the electrical insulating material that has adopted non-absorbency is made insulating sleeve, so insulating sleeve has the good water-fast water proofing property and the characteristic of dielectric insulation.Insulating sleeve is combined into three-phase four-wire system bus main line with single-phase insulation separation, interval has between phase and phase enlarged the area of dissipation and the heat-dissipating space of bus shell, maximally utilised the heat exchange of air, guaranteed the heat radiation of every phase bus-bars conductor, compare with integrated poured bus duct, have good heat dissipation, conductor unit cross section ampacity is big, line loss is low, save electric energy and save the advantage of cost.Phase-splitting insulation combined water proof bus mains system is owing to be single-phase insulation, fine solution on the problem of linear expansion, utilized the single-phase flexible sealing expansion pipe that is flexible coupling, thoroughly solve the flexible problem of stress concentration of linear expansion, stopped the generation of product cracking, the ruined serious potential safety hazard accident of insulating barrier.Phase-splitting insulation combined water proof bus mains system easily assembles, quick detachable, the unit is connected the waterproof and antiseepage that adopts dismoutability and connects way with the unit, so the whichever unit breaks down, can get rid of very expediently, at any time dismantled and assembled, can in time recover the function of product and use.The conductor of phase-splitting insulation combined water proof bus mains system and insulating sleeve are the ways of taking suit; so very be convenient to separating of metallic conductor and insulating sleeve material; be beneficial to the processing of recycling of materials and solid waste; concerning the user; use, the amortization cost of equipment had both been reduced; saved the environmental protection treatment expense of solid waste again; meet the regulation of country about recycling economy promotion law and Law on Environmental Protection; therefore, this technology of the present invention has good economic benefits and social benefit.
