Technical field

The present invention relates to a kind of intelligent tube type bus of bullet train traction power supply.

Background technique

Tube type bus, using more and more extensive in China's electric system, is especially existed due to its good electric property In bullet train traction power supply, the tube type bus advantage incomparable with conventional busbars.

But often its structural strength is not strong for existing tube type bus, can not effectively adapt to the use in bullet train field It needs, a kind of intelligent tube type bus of superhigh voltage DC insulation, has there is use as shown in publication number CN201721417630.4 The mode of reinforcing rib, the technical solution of the structural strength of Lai Tigao tube type bus.

But specific in use, since tube type bus internal structure is all cylindrical, so after long-time use, it is internal There can be certain torsion phenomenon, the structural strength of tube type bus can be greatly reduced, especially when internal structure severe bends When torsion, insulating capacity also has certain decline, it is easy to cause the generation of peril.

Summary of the invention

The purpose of the present invention is to solve the above the deficiencies in the prior art, propose a kind of bullet train traction power supply use Intelligent tube type bus.

A kind of intelligent tube type bus of bullet train traction power supply, including be successively socketed from inside to outside cast conductor, Insulating layer, shielded layer, protective layer, alumina ceramic layer and outer jointing jacket；

Wherein the material of cast conductor can obtain biggish sectional area and surface area by the design of cast for brass, So that conductor surface current density is evenly distributed.

The Ω shape protrusion of several circumferentially array distributions, the inner wall of the shielded layer are connected on the outer wall of the insulating layer It is equipped with the Ω connected in star to match with Ω shape protrusion.

The outer jointing jacket is equipped with several snap-type reinforcing ribs, and the snap-type reinforcing rib includes reinforcing muscle portion Point, horizontal buckle group and vertical buckle, the vertical buckle is connected with the bottom of reinforcing rib part, outside alumina ceramic layer Wall is equipped with the vertical card slot to match with vertical buckle, and the horizontal buckle group includes two horizontal cards being symmetrical set Button, the outer jointing jacket are spliced by multiple arcs pipe, are equipped on the side wall of the curved pipe and are matched with horizontal buckle Horizontal card slot.

Preferably, the end of the horizontal buckle is trapezoidal.

Preferably, the end buckled vertically is trapezoidal.

Preferably, the quantity of the snap-type reinforcing rib is three, and the quantity of the curved pipe is three.

Preferably, the material of the snap-type reinforcing rib is hard aluminium alloy.

Preferably, metal net shaped braiding layer is equipped with inside the shielded layer.

Preferably, the cross section of the reinforcing rib part is rectangle, and the lower semisection of reinforcing rib part is embedded in outer protection It covers in the square groove on outer wall

Preferably, the quantity of the Ω shape protrusion is 12.

The utility model has the advantages that

1, effectively insulating layer and shielded layer can be connected by multiple Ω shape protrusions, with and overcome due to The case where insulating layer is different from shielded layer material, reverses between each other after long-time use, can be big by Ω shape protrusion The big frictional force increased between insulating layer and shielded layer, and the raised surface for also corresponding to insulating layer simultaneously of Ω shape increases Several reinforcing ribs can effectively promote the structural strength of whole tube type bus.

2, the horizontal buckle in snap-type reinforcing rib can effectively connect two adjacent curved pipes, pass through water The cooperation of flat buckle and horizontal card slot, guarantees to be completely embedded between adjacent curved pipe, while vertical buckle is made pottery with aluminium oxide again Vertical card slot on enamel coating outer wall matches；It on the one hand, can be effectively by outer jointing jacket and oxidation by snap-type reinforcing rib Aluminium ceramic layer is closely coupled, and will not allow the phenomenon that reversing between the two；On the other hand, the reinforcement on snap-type reinforcing rib Muscle portion point can greatly promote the structural strength of whole tube type bus.
