Abstract

The utility model relates to an intensive bus duct which comprises an upper cover plate, a lower cover plate, a left side plate, a right side plate, a conducting bar and a joint assembly. The upper cover plate and the lower cover plate are fixedly connected with the left side plate and the right side plate to form a cavity. The conducting bar is disposed in the cavity formed by the upper cover plate, the lower cover plate, the left side plate and the right side plate. The upper cover plate, the lower cover plate, the left side plate and the right side plate are fixedly connected via fixing mechanisms. The joint assembly is fixedly connected on two ends of a bus duct body. According to the utility model, insulating cushion blocks are avoided, gaps are minimized, the shaft well chimney function of the bus duct is eliminated, the intensity is enhanced, the heat radiation performance is improved, the environment can be protected, materials are saved, and the processing cost is lowered.

Description

Concentration bus duct

Technical field

The utility model relates to a kind of concentration bus duct.

Background technology

Concentration bus duct is applicable to and exchanges three-phase and four-line, three-phase five-wire mode, frequency 50～60Hz, rated voltage is to 690V, the power supply-distribution system of rated operational current 250～5000A, auxiliary equipment as power supplying and distributing equipment in industrial and mineral, enterprises and institutions and the skyscraper, be specially adapted to the transformation of workshop, long-established enterprise, and present on the market concentration bus duct, its insufficient strength, heat dispersion are poor, in the time of breaking out of fire, can give out pernicious gas, not environmental protection, and its production cost of existing concentration bus duct is all than higher, waste material.

Summary of the invention

The purpose of this utility model is to overcome the defective of prior art, a kind of intensity height, perfect heat-dissipating, environmental protection are provided, can reduce production costs, economical with materials, concentration bus duct that performance is high.

For achieving the above object, the utility model adopts a kind of concentration bus duct, comprise upper and lower cover plate, left and right side plate, busbar, adapter assembly, described upper and lower cover plate and left and right side plate are fixedly connected to form a cavity, described busbar is arranged in the cavity of upper and lower cover plate and the formation of left and right side plate, is fixed together by fixed mechanism between described upper and lower cover plate, the left and right side plate, and described adapter assembly is fixedly connected on the two ends of bus duct body.

The utility model further is provided with again, and the outer surface of described left and right side plate is formed with many reinforcements.

The utility model further is provided with again, and described adapter assembly comprises L1 bus, L2 bus, L3 bus, N bus and PE bus, and each bus is close to setting in order, between each bus copper bar insulating barrier is installed, and described insulating barrier adopts the fire retardant mylar manufacturing.

The utility model further is provided with again, and described upper and lower cover, left and right side plate all adopt the aluminium alloy extrusions manufacturing.

In sum, the beneficial effects of the utility model are: the bus duct in-discard cross-over block, reduced the space, eliminated the vertical shaft chimney effect of bus duct, what the shell of bus duct adopted now is aluminium alloy extrusions, and be provided with many reinforcements, and strengthened intensity, also improved heat dispersion greatly, and played the effect of fixedly connected side plate, what described insulating layer material adopted in the past is poly-tetrafluoro orientation film, and pernicious gas is issued during breaking out of fire, and use now is fire retardant mylar 6023, not having pernicious gas when breaking out of fire sends, be a kind of environment-friendly products,, excellent conducting performance arranged because shell is an aluminium alloy extrusions, the PE line that replaces bus, reduce cost, also improved performance, and by above setting, the utility model has also been saved manufacturing materials, as the 1000A/5 bus duct was to be 4 (6*80)+3*80 with copper bar in the past, can be 4 (4*100) with copper bar now, and every meter bus is saved copper material 4.984Kg like this.
