Description
Technical field
The utility model relates to a kind of tubular bus, in particular to a kind of novel tubular bus.
Background technique
With China's rapid development of economy, demand of the entire society to electric power increasingly increases, at present 110kV and 220KV
Electric substation's low-pressure side is all made of 10kV, 35kV voltage class, with the increasing of main transformer capacity, the volume of step down side enter line side
Constant current is also continuing to increase, conventional rectangular bus technically be increasingly difficult to meet bus fever in structure and short circuit is electronic
The requirement of power, tubular bus come into being as the substitute of rectangular bus bar.Tubular bus is made using copper pipe or aluminium-alloy pipe
For conductor, a kind of bus bar products to insulate are applied with, are referred to as " tubular cable " in foreign countries, tubular dielectric bus has big electricity
The characteristics such as stream, high mechanical strength, good insulation, applied widely, so by more and more client's recognitions and acceptances.But
In the prior art, insulation performance is high not enough, and bus surface electric field distribution is uniform not enough, the skin effect coefficient of tubular bus
Not low enough, AC resistance is not small enough, and the power loss of bus compared with cannot be applicable in the occasion of more high current well.
Utility model content
The purpose of the utility model is to provide a kind of novel tubular bus to be mentioned by increasing shielded layer two and insulating layer two
The insulation performance of high tube type bus keeps bus surface electric field distribution more uniform, so that the skin effect coefficient on bus surface is more
Low, AC resistance is smaller, and the power loss of bus greatly reduces, and can be adapted for the occasion of more high current.
To achieve the above object, the utility model provides a kind of novel tubular bus, including tubular conductor, described tubular
Wrapped insulating layer one on conductor is surrounded with shielded layer one on the insulating layer one, is surrounded with insulating layer on the shielded layer one
Two, shielded layer two is surrounded on the insulating layer two, is surrounded with outer protective sleeve on the shielded layer two.
Compared with prior art, the beneficial effects of the utility model are, by increasing shielded layer two and insulating layer two, mention
The insulation performance of high tube type bus keeps bus surface electric field distribution more uniform, so that the skin effect coefficient on bus surface is more
Low, AC resistance is smaller, and the power loss of bus greatly reduces, and can be adapted for the occasion of more high current, and the utility model can
With for transformer low-pressure line-outgoing side.
The shielded layer two and shielded layer one are grounded as a further improvement of the utility model, can make pipe in this way
Shape bus surface electric field distribution is more uniform, and power loss is lower.
It is provided with drain wire in the shielded layer one and shielded layer two as a further improvement of the utility model, in this way
It can prevent from being struck by lightning, tubular bus is avoided to damage.
Insulating layer three, the outer protective sleeve are surrounded on the shielded layer two as a further improvement of the utility model,
On the insulating layer three, the insulation performance of tube type bus can be made more preferable in this way, bigger electric current can be born.
Anti- water segregation is provided between the outer protective sleeve and insulating layer three as a further improvement of the utility model,
Band can allow tubular bus to be preferably suitable for moist environment in this way.
The insulating layer one, insulating layer two and insulating layer three are ethylene three as a further improvement of the utility model,
Fluorine vinyl chloride copolymer can make tubular bus can be applied to the voltage of greater degree, additionally it is possible to prevent tubular lead in this way
Body is etched.
One layer of steel band is enclosed on the outer protective sleeve as a further improvement of the utility model, can be made in this way
Tubular bus is protected on surface during shipment, will not be worn.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model.
Wherein, 1 tubular conductor, 2 insulating layers one, 3 shielded layers one, 4 insulating layers two, 5 shielded layers two, 6 insulating layers three, outside 7
