Description

A kind of tubulose bus docking structure

Technical field

The utility model belongs to electrical equipment technical field, particularly a kind of tubulose bus docking structure.

Background technology

Tube type bus is a kind of power transmitting device of efficient conveying high-pressure electric current, tube type bus is compared with traditional rectangular bus bar, there is the features such as kelvin effect is good, unit section ampacity is large, radiating condition good, allowable stress is large, span is large, mechanical strength is high, electrical insulation properties is strong, main insulation stability of material is high, insulating process is reasonable, effectively can ensure the power supply reliability of power transmission and transformation net.Along with the growth steady fast of national economy, social power consumption linearly rises, and transforming plant main transformer capacity is constantly strengthened, and the rated current of main transformer low-pressure line-outgoing side also increases thereupon, and power department more and more uses tube type bus.

Two kinds of modes are connected with: 1, directly weld, its shortcoming is that weld bond resistance is large, weld bond easily ruptures between the tube type bus of current use; 2, hood type connects, in high voltage situation, connecting portion is owing to making securing member with bolt, connecting portion surface irregularity, insulation conducting tube bus connecting portion can not do shielding insulation process, easily there is ground connection and phase fault by people, animal and other object brought into incidental contact, be unfavorable for safe operation.

For overcoming the defect that above-mentioned pipe bus connects, the patent No. be 200410052284.5 patent propose a kind of connector of compound conductive tube, this connector of compound conductive tube is made up of non magnetic opening stainless steel sleeve and opening conducting metal cover, for insulating, conducting tube bus is connected uses with insulation conducting tube bus, it is large that it holds power, contact resistance is little, meets big current conveying.But the connector of compound conductive tube of this structure, complex process during connection, again layer overlaps, joint external diameter is large, is unfavorable for later stage insulation recovery process, and owing to being all locked by outside stainless steel sleeve between opening conducting metal cover and bus, hidden danger point is many.

Utility model content

For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of tubulose bus docking structure, its innovative point is: mainly comprise a pair symmetrically arranged tubulose bus bulk A and bus bulk B, and the electro-conductive liner pipe that is embedded in the inner joint of bus bulk A, bus bulk B;

The joint surface of bus bulk A is provided with the through hole on the inside and outside surface of some conducting bus bulk A, one end of described electro-conductive liner pipe just embeds in this bus bulk A, and the end face of bus bulk A and electro-conductive liner pipe center outer surface full weld are fixed, and fix in the end outer surface spot welding of the through hole of bus bulk A and electro-conductive liner pipe;

The inner joint of bus bulk B is distributed with some grooves extending to end face along bus bulk long axis direction, is set with a lock sleeve at the joint of described bus bulk B, and the other end of the joint of bus bulk B and electro-conductive liner pipe is locked by this lock sleeve.

Further, described lock sleeve is a metallic sheath, metallic sheath has one and axially extends and through opening along it; Lock sleeve welds at opening part after being locked at bus bulk B joint.

The utility model has the advantage of:

(1) tubulose bus docking structure of the present utility model, at the embedded electro-conductive liner pipe of the inner joint of bus bulk A, bus bulk B, wherein, bus bulk A and electro-conductive liner pipe are by being welded and fixed, and bus bulk B and electro-conductive liner pipe are fixed by lock sleeve; This structure, not by being directly welded and fixed, thus avoids the shortcoming that weld bond resistance is large, weld bond easily ruptures; Meanwhile, electro-conductive liner pipe is embedded in the inner joint of two bus bulks, makes joint surface be tending towards smooth attractive in appearance, avoids the phenomenon that joint external diameter is large simultaneously, and then be beneficial to later stage insulation recovery process; Only have while fix with lock sleeve, thus reduce potential safety hazard;

(2), in the utility model, lock sleeve is an open metal cover, and this lock sleeve is convenient to be enclosed within outside joint under open state, then by wlding, opening part is welded, and then stainless steel sleeve is tightly wrapped in outside joint, strengthen the intensity of joint, also have protective action simultaneously;

(3), in the utility model, the joint surface of bus bulk A is provided with the through hole on the inside and outside surface of some conducting bus bulk A, thus facilitates operation personnel electrical verification, thermometric, handling safety.
