Abstract
The utility model discloses a kind of novel oval coil machine body structure, comprise iron core, low-voltage coil and high-tension coil, iron core is the ellipse in closed assembly step by step, low-voltage coil and high-tension coil are the ellipse of coiling, low-voltage coil is sleeved on outside unshakable in one's determination, and high-tension coil is sleeved on outside low-voltage coil.The utility model is mainly applicable to the machine body structure of 10KV ~ 35KV laminated core oil-filled transformer, has the advantages that manufacturability is strong, easy to make, anti-short circuit capability is strong, safe and reliable.
Description
Technical field
The utility model relates to a kind of coil machine body structure.
Background technology
The oval coil that major part producer adopts not is real ellipse, but Long Circle, be exactly the main of the iron core of transformer thickeied, outer that is unshakable in one's determination and coil becomes Long Circle by a pure circle, and this oblong coil machine body structure mainly exists following problem:
1, Long Circle coil winding manufacturability is poor, do not seamlessly transitted to straight line portion by semi-circular portions in coil-winding process, coil rectilinear direction can to extending out, poor stability, short-axis direction (i.e. straight sides) the dimension overproof problem easily occurred in winding process, coiling speed is slow, and mass of coil difficulty controls, and directly has influence on life-span and the performance of transformer;
2, Long Circle coil anti-short circuit capability is poor, when transformer short-circuited outside phenomenon, the electric current of larger than rated current tens times will be flow through in transformer coil, coil can produce very large electric power and superheating phenomenon, Long Circle coil is under the effect of short circuit electric work power, coil is each point unbalance stress on girth, and as easy as rolling off a log unstability, causes coil burnout.
Summary of the invention
For solving the problems referred to above that existing coil machine body structure exists, the utility model provides a kind of novel oval coil machine body structure, and its technical scheme adopted is:
Comprise iron core, low-voltage coil and high-tension coil, iron core is the ellipse in closed assembly step by step, and low-voltage coil and high-tension coil are the ellipse of coiling, and low-voltage coil is sleeved on outside unshakable in one's determination, and high-tension coil is sleeved on outside low-voltage coil.
This structure achieves real ovalization coil winding, and coil winding manufacturability is strong, and coil winding is easy, and short-axis direction size easily controls, and coiling speed is fast, and coil each several part seamlessly transits, and coil uniform force, anti-short circuit capability is strong.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the vertical view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As depicted in figs. 1 and 2, iron core 1 adopts ovalization closed assembly step by step, and low-voltage coil 2 and the coiling of high-tension coil 3 ovalization, overlap high-tension coil 3 around or be sleeved on low-voltage coil 2, is sleeved on by low-voltage coil 2 on unshakable in one's determination 1.This structure is mainly applicable to the coil machine body structure of 10KV ~ 35KV laminated core oil-filled transformer, improves production efficiency, product quality and product anti-short circuit capability by the coil machine body structure after ovalization.
