Tube type bus is one of crucial part of appliance in electric power power transmission and transformation system, to power transmission and transformation system and power equipment
Safe and reliable operation play a crucial role.Currently, the tube type bus that there is now is the smooth circle copper in surface mostly
Pipe, and as the diameter of increases tubular bus of conveying voltage and current grade also increases with it, not only increase manufacturing cost with
Project cost, and in large span can sag bent, cause bus junction be deformed with poor contact and cause to overheat
Overvoltage causes the accident.In addition, copper valence constantly rises due to the shortage of copper resource and the contradiction of consumption rapid growth, make with
Copper material is that the cost of the tubular bus of raw material rises rapidly, and product competitiveness in the market receives serious restriction.
In existing tube type bus, some uses aluminium alloy as busbar pipe to reduce cost, but aluminium
Alloy conductive performance is lower, and heat dissipation performance is poor, can largely influence the fan-out capability and efficiency of cable, in the big electricity of transmission
Stream process kind causes very big energy loss.The method using Cu-AL pipe or aluminum-cladding copper pipe also, this kind of tube type bus are easy
It is influenced by environment, especially encounters the snowy weather that rains, be easy to cause certain corrosion, since the presence of defect can be led
The failure for causing busbar pipe, seriously threatens the safe operation of power grid.
Utility model content
It conducts electricity very well and safe and reliable composite pipe bus the purpose of this utility model is to provide a kind of.
The technical solution that the utility model solves above-mentioned technical problem is as follows: a kind of composite pipe bus, including contact tube base
Body layer, the copper alloy layer being coated on the contact tube base layer inner wall, the aluminium being coated on the contact tube base layer outer wall
Alloy-layer and the insulating protective layer being set to outside the aluminium alloy layer；The contact tube base layer is magnesium alloy material；
The copper alloy layer includes thin segment, the changeover portion connecting with thin segment and the heavy wall connecting with the changeover portion
Section.
Further, there is heat dissipation channel inside the composite pipe bus.
Further, the insulating protective layer is made of polytetrafluoroethylene (PTFE).
Further, which is seamless tube body.
Further, which is made of extrusion forming mode.
The utility model has the following beneficial effects:
The composite pipe bus service performance is more excellent, and comprehensive benefit is higher, uses magnesium alloy for the contact tube base of material
Body layer can effectively realize the lightweight of conducting tube bus, the sag bent of contact tube base layer when avoiding large span；Pass through
Insulating layer improves weatherability, anticorrosive property, and eliminates the influence of the factors such as extraneous moisture, dust, reliable with height
Property, prolong the service life；And by the copper alloy layer of inner wall not uniform thickness, own wt is not only alleviated, also reduces metal throwing
Dosage reduces cost in turn；And by the structure of the not uniform thickness, so that contact tube base layer inner wall is formed certain linear structure, have
Help improve heat dissipation performance.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is the utility model schematic cross-section；
Appended drawing reference shown in Fig. 1 to Fig. 2 respectively indicates are as follows: 1- contact tube base layer, 2- copper alloy layer, 3- aluminium alloy
Layer, 4- insulating protective layer, 5- heat dissipation channel, 201- thin segment, 202- changeover portion, 203- heavy wall section.
Specific embodiment
The principles of the present invention and feature are described below in conjunction with attached drawing, example is served only for explaining that this is practical
It is novel, it is not intended to limit the scope of the utility model.
As shown in Figure 1 to Figure 2, a kind of composite pipe bus, including contact tube base layer 1, be coated in contact tube base layer 1
It copper alloy layer 2 on wall, the aluminium alloy layer 3 being coated on 1 outer wall of contact tube base layer and is set to outside aluminium alloy layer 3
Insulating protective layer 4；Contact tube base layer 1 is magnesium alloy material.There is heat dissipation channel 5 inside the composite pipe bus.
The composite pipe bus is seamless tube body, and entirety uses extrusion forming mode to be made, no-welding-seam, structural strength
Height, long service life.
Contact tube base layer 1 is used as base layer, while being also used as shielded layer and heat dissipating layer, and elasticity modulus is high, effectively keeps away
Exempt from contact tube sag bent when large span, avoid bus junction be deformed with poor contact and cause to overheat overvoltage
Problem.And it facilitates reduction pair with good heat dissipation performance, excellent electromagnetic shielding characteristic and excellent damping capacity
The electromagnetic interference problem of other electronic equipments guarantees the transmitting and stabilization of communication signal, and reduces noise.
The copper alloy layer 2 of internal layer cladding has good electric conductivity, and the skin effect of high-frequency signal can guarantee that signal exists
Transmission in the layers of copper of inner surface, as the conductive layer for being used for transmission current detection signal, in addition, copper alloy has preferable extend
Rate and intensity improve the comprehensive mechanical property and electric conductivity of multiple tube.
Copper alloy layer 2 includes thin segment 201, the changeover portion 202 connecting with thin segment 201 and connect with changeover portion 202
