Description
Technical field
The utility model is related to lead link structure at a kind of winding protruding head, belongs to technical field of transformer equipment.
Background technology
China's high-power transformer when being designed, based on the consideration of the factors such as electrical strength, mechanical strength and temperature rise,
Lead between coil and sleeve pipe is generally more from copper pipe lead, and using phosphor-copper weldering between winding protruding head original line and copper pipe
Mode is attached, as shown in Figure 1.The frame mode advantage is reliable connection, is had the disadvantage due to by winding protruding head original line length
Limited, it is necessary to which, near device body welding operation, because operating space is limited, and welding slag is easily splashed down in device body in welding process,
Cause a hidden trouble influence transformer reliability service.
Utility model content
The utility model purpose is to provide lead link structure at a kind of winding protruding head, by introducing one section of annealed copper strand wire,
Pressure joint is used between winding protruding head original line and annealed copper strand wire, phosphor-copper weldering is carried out between annealed copper strand wire and copper pipe lead, so that
Make pad away from device body, prevent potential safety hazard, efficiently solve above mentioned problem present in background technology.
The technical solution of the utility model is：Lead link structure at a kind of winding protruding head, it is former comprising coil, winding protruding head
Line, joint, copper pipe lead, pressure joint and annealed copper strand wire, the winding protruding head original line are arranged at winding protruding head, annealed copper strand wire
One end interconnected by joint and copper pipe lead, the other end is interconnected by pressure joint with winding protruding head original line, is connect
Head is made for phosphor-copper welding.
The sectional area of the annealed copper strand wire matches with winding protruding head original line.
Being wrapped outside the pressure joint has insulating barrier, and thickness and the voltage class of insulating barrier match.
The beneficial effects of the utility model are：By introducing one section of annealed copper strand wire, winding protruding head original line and annealed copper strand wire it
Between use pressure joint, phosphor-copper weldering is carried out between annealed copper strand wire and copper pipe lead, so that pad prevents safety away from device body
Hidden danger, with low cost, easy to operate, structure reliability, with very big practicality, it is easy to popularization and application.
Brief description of the drawings
Fig. 1 is structure chart of the present utility model；
In figure：Coil 1, winding protruding head original line 2, joint 3, copper pipe lead 4, pressure joint 5, annealed copper strand wire 6.
Specific embodiment
Below in conjunction with accompanying drawing, by embodiment, the utility model is described in further detail.
Lead link structure at a kind of winding protruding head, comprising coil 1, winding protruding head original line 2, joint 3, copper pipe lead 4, pressure
Joint 5 and annealed copper strand wire 6, winding protruding head original line 2 are arranged on coil 1 and lift one's head place, and one end of annealed copper strand wire 6 is by joint
3 are interconnected with copper pipe lead 4, and the other end is interconnected by pressure joint 5 with winding protruding head original line 2, and joint 3 is welded for phosphor-copper
Connect and be made.
The sectional area of the annealed copper strand wire 6 matches with winding protruding head original line 2.
Being wrapped outside the pressure joint 5 has insulating barrier, and thickness and the voltage class of insulating barrier match.
In actual applications, the winding protruding head original length in reserve of line 2 is suitably shortened, and provides what one section of suitable cross-section was accumulated again
Annealed copper strand wire 6, during assembling, first welds one end of annealed copper strand wire and copper pipe lead phosphor-copper, now, due to no longer receiving winding protruding head former
Line length is limited, can be carried out in the good place away from device body, it is to avoid the defect of prior art.After welding, then will be soft
The other end of copper stranded conductor is wrapped suitable thickness by the original cold weld of line 2 of pressure joint 5 and winding protruding head further according to voltage class
Insulation.
