Summary of the invention:

The purpose of this utility model is to provide construction standardization according to above-mentioned deficiency, the round bus duct of the copper-aluminium transition of modularization, and it overcomes the problem of above-mentioned copper aluminium contact technique deficiency effectively, and has all performances and the effect that copper bus duct has.Be convenient to installation, maintenance, energy-conservation, material-saving, fire prevention, good waterproof performance, safe and reliable etc., particularly save the copper resource, product cost descends at double, it has transmission of electricity, two kinds of mains systems of distribution, be widely used in the occasion that capacity such as skyscraper, high residential building, factory, indoor and outdoor are big, branch is many, at present just in force.

The utility model is to realize like this, this round bus duct is hereinafter to be referred as bus, it is made of bus, jack box, inlet wire case, elbow, joint case, erection bridge, shell adopts short steel pipes or the aluminium-alloy pipe through processing, main fixing two insulation board and the protective action of rising, and conductor adopts the aluminum pipe of 90% length, the conductor two ends are with the copper pipe of 8% length, take the copper-aluminium transition solder technology, i.e. copper and aluminium welding is integral, and the conductor of bus is welded into conductor 1 by the short copper pipe of aluminum pipe and conductor two ends.Bus is made up of conductor 1, short steel pipes 2, two insulation board 3, long bolt 4, heat-shrink tube 5, cushion rubber 6, conductor 1 is positioned in the short steel pipes 2 for 90 ° by two insulation board 3 mutual deviations, the one end is fixed with inlet wire case C, and the other end is fixed with several jack boxes B, or joint case E, elbow D.Bus length is by some short steel pipes 2 combination, and short steel pipes 2 steps and seam are embedded with two exhausted plates 3, are lined with cushion rubber 6, conductor 1 supporting point is with heat-shrink tube 5, is strained and fixed by long bolt 4, and two insulation boards 3 clamp conductors 1 combination and fix.

Jack box B: the copper sleeve plug connector of jack box B, adopt copper material to make and silver-plated processing, it is core in the bus-bar system, be the joint case be again feeder pillar, similar threeway.The copper pipe of bus inserts in the silver-plated copper joint also fastening.Be communicated with main line and branch, branch connects switch-box, automatic switch control, protection output current by the sound insert-connecting plate.Jack box is the place that bus connects, grafting is the most concentrated, and is easy to maintenance.This bus can realize that with aluminium for copper technology, the structural design of jack box has important relationship.

Inlet wire case C: be divided into busbar or cable connected mode by inlet wire mode difference, inlet wire case major function is that electric power incoming line is converted to bus-bar system by the silver-plated copper joint.

Elbow D: bus is turned, and realizes by the bend part connection bus.

Joint case E: bus is generally produced by several full-lengths, and bus is connected with bus by joint case extended link, also can extend by jack box and elbow on demand.

Be that copper accounts for 14%～18%, aluminium 82% with the copper al proportion comprehensively with Up Highway UHW, jack box, inlet wire case, elbow, joint case.

Erection bridge F: for several meters long heavy again buses is easy, install preferably, install in two steps and be very important, earlier erection bridge is put down, vertically installed, adjusts by horizontal at the scene, it is just easy that bus, jack box, inlet wire case etc. are installed then, erection bridge is in factory's die production, the technology that difficulty is big is finished in factory, realized the installation batch production.After erection bridge was zinc-plated, the double ground connection main line of doing had played the three-phase five-wire mode effect, and wherein the three-phase and four-line shielding when skyscraper is struck by lightning, avoids the ground connection main line that three-phase and four-line is discharged in metal tube, makes the low-pressure system electric equipment exempt from thunderbolt.Therefore utilize erection bridge to make both safety, reliable of ground connection main line (PE line), save copper material again, decades, the operating experience of power distribution equipment was told us, and is practical.
