Description
(1) technical field
The present invention relates to voltage-regulating winding structure technical field, particularly to a kind of ULTC tap-changing windings and lead-in wire thereof
Structure.
(2) background technology
Present stage, in order to meet road conditions requirement to transformer impedance drop size to transformer transporting size and user, sometimes
Tap-changing windings need to be designed to single layer cylinder formula structure, and be arranged in the inside of transformer body, i.e. place against core limb,
For the transformator that low capacity, small area analysis, tapping range are relatively small, by the axial component of tap-changing windings electric current and flow through line
The electric current that circle end occurs is little on the impact of vented fire electric current, does not typically interfere with the safe operation of transformator；But for especially big appearance
From the point of view of the transformator of amount, big electric current, tapping range (± 10-± 14 are the biggest) greatly, if still using single layer cylinder formula structure,
With a circulation transformator: model ZZDFPZ-405200/500, rated voltageAs a example by,
Its pitch angle alpha is up to 2.1, and the axial component electric current of the every circle of coil is 360A, and more seriously transformator is in limit tap fortune
During row, need to be together in series by each tapping step, the electric current of such tap-changing windings upper and lower side outlet is up to ampere up to ten thousand；At this moment will
In the loop of folder, the loop of arm-tie composition and window composition unshakable in one's determination, induce the highest vented fire electric current, thus cause additional damage
Consumption increases, and even produces hot-spot phenomenon.
For this both at home and abroad some expert through argument and analysis repeatedly, take series of measures, the most most effective have most
Representational method has: one is most end one-level unshakable in one's determination to be removed, and changes copper coin into, utilizes the high conductivity of copper, reduces additional damage
Consumption and local temperature rise；Two is side post arm-tie and upper clamping piece to be insulated, and uses annealed copper strand wire instead and connects, alleviate to a certain extent by
The problem that local temperature rise caused by and conduction rate variance less in other post arm-tie cross section is too high.But both approaches is for the above-mentioned change of current
For transformator, also having its weak point, one is that progression is many, electric current is big, conductor cross-section is big due to tap-changing windings tap, adjusts
Pressure winding upper and lower end parts outlet difficulty；On the two pressure regulation tap leads being in addition at the tap of transformator place outside circulating current, quilt
Other tap lead sealed in also flows through electric current, so can cause transformer lead resistance loss, and current-carrying tap lead institute
In the path surrounding metal structures part passed through, stray loss increases, and directly affects the performance indications of transformator, even can cause gold
Belong to the generation of structural member hot-spot；Three is to be reduced according to the effective cross-section that above-mentioned first method is unshakable in one's determination, causes change
Depressor open circuit loss, no-load current and noise increase.
(3) summary of the invention
The present invention is in order to make up the deficiencies in the prior art, it is provided that a kind of simple in construction, be easy to outlet, easy to operate, feasibility
Good ULTC tap-changing windings and pin configuration thereof.
The present invention is achieved through the following technical solutions:
A kind of ULTC tap-changing windings and pin configuration thereof, including the tap-changing windings A against core limb, its feature exists
In: being orderly arranged outside each oil duct A, paper web and oil duct B at tap-changing windings A, the outside of oil duct B is provided with tap-changing windings B, its
In, tap-changing windings A be right around to, tap-changing windings B be a left side around to；Lift one's head in the upper end of tap-changing windings A and tap-changing windings B and lower end is touched
Head causes shunting switch after being connected respectively.
Tap-changing windings by original one, is designed to two tap-changing windings, leaves cooling between two coils by the present invention
Oil duct, considerably increases area of dissipation, and the winding of two tap-changing windings is contrary, makes pyller sense according to electromagnetic induction principle
Magnetic flux cancel out each other, effectively prevent vented fire electric current.
The more excellent technical scheme of the present invention is:
The width of described oil duct A and oil duct B is 7mm, and the thickness of paper web is 8mm.
The present invention, according to electromagnetic induction principle, uses around to two contrary tap-changing windings, adds these two in advance
The upper end of tap-changing windings lift one's head and lower end lift one's head be connected respectively after cause the technological measures such as shunting switch, efficiently solve
There is the vented fire electric current of sensing in axial current component and tap-changing windings end, eddy-current loss that tap lead electric current causes, spuious
Loss, resistance loss increase and tap lead connects difficult problem, have saved raw material, it is ensured that the performance of transformator refers to
Mark, it is to avoid hot-spot phenomenon, is beneficial to design the on-load voltage regulation converter power transformer that high-capacity, big electric current and tapping range are big
(± 200KV-± 800KV) and power transformer tap-changing windings.
Present configuration is simple, it is simple to outlet, easy to operate, and feasibility is good, can effectively weaken and even avoid vented fire electricity
The voltage-regulating winding structure of stream and lead design thereof, improve transformator operational reliability and economy.
