Composite guide fulgurite bus is the conductor wire for delivery of power frequency heavy-current, and its live flow is large, and temperature rise is low, and mechanical strength is high, can improve operating safety factor, is being used in recent years the electric power transfer of wind turbine generator.

Existing composite guide fulgurite bus; such as Chinese utility model patent; publication number is CN2660752; name is called the high disclosed a kind of structure of full-shield protection conductive metal pipe bus of coincideing; the insulating barrier that it comprises the pipe bus conductive body and covers the core surface; the connectivity port of pipe bus conductive body be processed into special-purpose gold utensil connector adaptive be connected aspect, ground plane rabbet in insulation material layer, extexine is that current potential is zero protective layer.The surface coverage insulating barrier of pipe bus conductive body comprises from the inside to the outside high pressure resistant insulation enamelled coating, configuration high pressure resistant insulation material layer, cover insulation screen, filler and strengthens outer jacket; The ground plane interlocking is in described each insulating barrier.There is the defective aspect following two in the pipe bus of this structure when work: on the one hand, space shared when the multi-channel power transmission passage is worked simultaneously is larger, and on the other hand, the radiating effect of this pipe bus is relatively poor.

Summary of the invention

It is little that the technical problems to be solved in the utility model provides the space that takies when a kind of multi-channel power transmission passage is worked simultaneously, and the good composite guide fulgurite bus of radiating effect of pipe bus.

For solving the problems of the technologies described above, the utility model adopts a kind of like this composite guide fulgurite bus, the A phase conducting tube bus that this conducting tube bus comprises at least two hollows and B be conducting tube bus mutually, described A phase conducting tube bus places the inner chamber of described B phase conducting tube bus, is provided with successively from inside to outside inner insulating layer, shielding equipotential layer and heat dissipating layer between described A phase conducting tube bus and B phase conducting tube bus.

As a kind of preferred implementation of the present utility model, described conducting tube bus also comprises the C phase conducting tube bus of a hollow, described B phase conducting tube bus places the inner chamber of described C phase conducting tube bus, is provided with successively from inside to outside inner insulating layer, shielding equipotential layer and heat dissipating layer between described B phase conducting tube bus and C phase conducting tube bus.

As a kind of improvement of the present utility model, on the outside wall surface of described C phase conducting tube bus, be provided with successively from inside to outside inner insulating layer, shielding equipotential layer, heat dissipating layer and external insulation layer.

Inner insulating layer of the present utility model is made and is attached on the outside wall surface of each conducting tube bus by insulating material, described shielding equipotential layer is made and is attached on the outside wall surface of described inner insulating layer by flexible metallic material or electrically-conducting paint, described heat dissipating layer is made and is attached at by heat-conducting insulation material on the outside wall surface of described shielding equipotential layer, and described external insulation layer is made and is attached on the outside wall surface of described heat dissipating layer by insulating material.

As further improvement of the utility model, in described heat dissipating layer, also be provided with some the vent passages that extend along its length direction.

The beneficial effects of the utility model are: after having adopted said structure, so that the multi-channel power transmission passage combines, volume is little, has saved the space; The utility model is owing to be provided with heat dissipating layer between the pipe bus, thereby make the pipe bus when work, have good heat dispersion, in addition, the utility model preferably arranges some vent passages in heat dissipating layer, thereby produced stack effect in when work, the heat that the pipe bus is produced can distribute sooner, better heat-radiation effect.
