Description

The reinforced heat resisting diameter enlarging bus bar of a kind of improvement

Technical field

The present invention relates to electric wire field, be specifically related to the reinforced heat resisting diameter enlarging bus bar of a kind of improvement.

Background technology

Bus is generally used for electrical equipments such as connection and the transformator of voltage power distribution equipments at different levels in transformer station and corresponding The effect of the connection of power distribution equipment, i.e. bus is to collect, distribute and transmit electric energy.In the power transformation being positioned at High aititude geographical position Standing, the electric field of bus used by it, magnetic field, audible noise and radio interference level can substantially exceed related request, and this is not only Can bring environmental pollution, and can produce a large amount of energy loss, the best technique means solving these problems are that increase bus is straight Footpath.

At present, the traditional method increasing bus diameter is: 1, increase steel core or the area of aluminium lamination, but this will certainly increase mother The weight of line, thus add the load of bus two bottom bearing tower；2, employing takes out the mode of stock, i.e. the mother of common lay configuration Line extracts some single lines relatively to increase bus stranded layer out, thus reach expanding purpose, but this expanding mode of stock of smoking Enlarging rate is very limited, it is difficult to meet the high altitude localities requirement to bus.

To this end, Chinese invention patent ZL201420223833.X, disclose a kind of transformer station aluminum pipe supporting type heat resisting and expand Footpath bus, including expanding stay tube made of aluminum and the conductive layer being stranded in expanding stay tube periphery.But, this diameter enlarging bus bar Have the disadvantage that 1, the cross section of its heat-resisting aluminium alloy single line is circle, when by twisted for the aluminium alloy single line of many circular cross-sections Behind the periphery of embossing aluminum pipe, adjacent two aluminium alloy single lines are linear contact lay, there are gap the most between the two, thus cause mother Line outer surface curvature radius changes, and then causes bus surface field intensity to raise, and reduces the initial corona voltage of bus, limit Make the bus use in high altitude localities transformer station；2, after many aluminium alloy single lines are stranded, its stranded compactness is low；3, aluminum is used Pipe is as support, and aluminum is the most softer, it is easy to be crushed, and support effect is undesirable.

It addition, the conductive layer of a lot of buses all uses Z-type and S type conduction single line, between Z-type and Z-type conduction single line closely Degree is not tight, the loosest.

Summary of the invention

In order to overcome the deficiencies in the prior art, it is provided that the heat resisting diameter enlarging that a kind of anti-extrusion is more preferable, compactness is good Bus.

For achieving the above object, the present invention provides a kind of reinforced heat resisting diameter enlarging bus bar, including by expanding aluminum pipe and stranded At the Z-shaped conductive layer of expanding aluminum pipe periphery, described Z-shaped conductive layer includes many along the circumferentially distributed Z-shaped of expanding aluminum pipe Conduction single line, adjacent two Z-shaped are conducted electricity between single line, be face between Z-shaped conduction single line and expanding aluminum pipe contacts；Described The outer peripheral face of Z-shaped conduction single line is plane, and in adjacent two Z-shaped conduction single line, a Z-shaped conduction single line outer peripheral face Edge extend to another root Z-shaped conduction single line outer peripheral face edge；One layer of aluminium foil is added outside described Z-shaped conductive layer Layer.

Preferably, described Z-shaped conduction single line includes suitable protuberance and concave part, adjacent two conduction single lines In, the protuberance of a conduction single line is mutually stranded with the concave part of another root conduction single line.

The beneficial effects of the present invention is:

Compared with prior art, the simple in construction of the present invention, aluminum pipe as support structure, owing to aluminum pipe is softer, not anti-extrusion, So adding one layer of aluminium foil layer outside aluminum pipe, all of holding capacity is on aluminium foil, and it is not in the case of increasing conductive layer area Considerably increase the diameter of bus, and then meet the high altitude localities requirement to diameter enlarging bus bar；It addition, in the application, conduction is single Line uses Z-shaped, between adjacent two conduction single lines, is face and contact between conduction single line and expanding stay tube, thus raising is led The electricity stranded compactness of single line, however, to ensure that compactness is more preferable, is pricked into Z-shaped conductive layer by aluminium foil layer；Meanwhile, led by many The outer peripheral face unusual light of the conductive layer that electricity single line is constituted.
