Abstract
The utility model provides a kind of coaxial-type high current sleeve pipe temperature-rise test device, and its main points is：The front and back end portses of stainless steel cylinder are in flange shape, and copper ring flange and adpting flange are connected respectively, constitute drum-shaped fuel tank；The soft one end of each Ω shape copper connects an outer copper line, and the soft other end of all Ω shapes copper is trapped among all outer copper lines on the outside of drum-shaped fuel tank and coaxial with drum-shaped fuel tank by radially fixed on the lateral surface of copper ring flange；There is the inner copper line that high current inside pipe casing binding post that can be with being tested is connected in drum-shaped fuel tank, one end of inner copper line is fixed on copper ring flange medial surface with vertical.Good effect of the present utility model is：As a result of the galvanic circle of coaxial configuration, the influence in magnetic field between wire is reduced significantly, so as to be obviously reduced the influence of kelvin effect and approach effect.
Description
Technical field
The utility model is related to a kind of transformer high current sleeve pipe temperature-rise test device, and the high current refers to that 1 Wan An is trained
Electric current above.
Background technology
At present in the experiment of transformer high current sleeve pipe temperature rise, because test current is very big, power supply to high current sleeve pipe
Connection conductor cross sectional area need it is very big, so in practice typically using many conductors it is used in parallel, such as by power supply with two
Heavy in section conductor is directly connected to sleeve pipe two ends.Because conductor size is big, the effect of kelvin effect and kindred effect will be non-
Chang Mingxian, can cause conductor seriously to generate heat, and cause experiment can not continue to carry out.
The content of the invention
In order to solve the above technical problems, the purpose of this utility model is to provide a kind of coaxial-type high current sleeve pipe temperature rise test
Device.
What the purpose of this utility model was realized in：The front and back end portses of stainless steel cylinder are in flange shape, and copper ring flange connects
It is connected on stainless steel cylinder rear flange, adpting flange is connected on stainless steel cylinder forward flange, on adpting flange lateral surface also
Be connected the counter flange that can be docked with the high current casing flange tested, and they constitute drum-shaped fuel tank；Each Ω shape copper is soft
One end connect an outer copper line, all Ω shapes copper soft other ends by copper ring flange the radially uniform copper ring flange that is fixed on
On lateral surface, it is trapped among all outer copper lines on the outside of drum-shaped fuel tank and coaxial with drum-shaped fuel tank, has on each outer copper line
Two dielectric support blocks, are separately fixed on the forward and backward flange of stainless steel cylinder；Having in drum-shaped fuel tank can be with the big electricity tested
The inner copper line of inside pipe casing binding post connection is flowed, one end of inner copper line is fixed on copper ring flange medial surface with vertical.
Application method is that the high current sleeve pipe tested is arranged on the utility model, is specifically big by what is tested
Electric current casing flange is connected on counter flange of the present utility model, makes inside pipe casing binding post and the utility model inner copper line
Connection.The external wiring terminal and outer copper line of sleeve pipe are coupled with the two ends of power supply, and the conduction for constituting a coaxial configuration is returned
Road；Load transformer oil in drum-shaped fuel tank, you can high current is passed through according to the requirement of testing standard and carries out sleeve pipe temperature rise examination
Test.
Compared with prior art, good effect of the present utility model is：As a result of the galvanic circle of coaxial configuration, greatly
The big influence for reducing magnetic field between wire, so as to be obviously reduced the influence of kelvin effect and approach effect, makes the conduction of conductor
Sectional area can be fully used, it is to avoid the problems of excessive heat of connection conductor；Secondly, the utility model uses stainless steel fuel tank
The mode being combined with conducting copper, not only reduces material cost, and manufacture processing is more prone to.

The utility model is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is schematic diagram of the present utility model.
Fig. 2 is Fig. 1 B portions enlarged drawing.
Fig. 3 is Fig. 1 A direction views.
Fig. 4 is that the high current sleeve pipe tested is arranged on the schematic diagram on the utility model.
Embodiment
Referring to Fig. 1-3, the front and back end portses of stainless steel cylinder 11 are in flange shape, and copper ring flange 4 is connected to after stainless steel cylinder
On flange 13, adpting flange 5 is connected on stainless steel cylinder forward flange 12, and being also connected on adpting flange lateral surface can be with subject
The counter flange 6 that the high current casing flange 83 tested is docked, they constitute drum-shaped fuel tank 1；One end of each Ω shape copper soft 3 connects
Connect an outer copper line 2, the other ends of all Ω shapes copper soft 3 by copper ring flange the radially uniform lateral surface for being fixed on copper ring flange
On, it is trapped among all outer copper lines on the outside of drum-shaped fuel tank and coaxial with drum-shaped fuel tank, there are two on each outer copper line absolutely
Edge support block 9, is separately fixed on the forward and backward flange of stainless steel cylinder；Having in drum-shaped fuel tank can be with the high current set tested
The inner copper line 7 of the internal wiring terminal 82 of pipe 8 connection, one end of inner copper line is fixed on copper ring flange medial surface with vertical.
Referring to Fig. 4, application method is, the high current sleeve pipe 8 tested is arranged on the utility model, and being specifically will be by
The high current casing flange 83 of experiment is connected on counter flange of the present utility model, makes inside pipe casing binding post 82 and this reality
Connected with new inner copper line.The external wiring terminal 81 and outer copper line of sleeve pipe are coupled with the two ends of power supply, constitute one together
The galvanic circle of axle construction；Load transformer oil in drum-shaped fuel tank, you can high current is passed through according to the requirement of testing standard
Carry out sleeve pipe temperature rise test.
