Abstract
The utility model discloses a dry-type low-partial discharge winding which belongs to the field of electric transmission and transformation equipment and comprises a coil, a head terminal and an end terminal, wherein the head terminal is arranged at the upper part of the coil; the end terminal is arranged at the lower part of the coil; and the length of the head terminal and the end terminal is 120mm respectively. Compared with the prior art, the dry-type low-partial discharge winding has the characteristics of reasonable design, simple structure, easy processing, low production cost, convenience in operation, low partial discharge, etc.
Description
Technical field
The utility model relates to the power transmission and transforming equipment field, and specifically winding is put in the low office of dry type.
Background technology
As using electric unit, the safe operation that guarantees transformer is first-selected.For dry-type transformer, examining its partial discharge quantity is the prerequisite that insulate and whether wear out, if the limit value above national Specification is put in office, then there is very big potential safety hazard in transformer.For reduce dry-type transformer the office high-volume, manufacturing firm has to improve manufacturing cost.
The two ends of winding generally all are the electrified bodies that exposes, and it becomes the position that the outside emphasis of partial discharge quantity is considered, just outside creepage distance apart from earthy distance that iron core and folder etc. is located.Creepage distance is big more, and then partial discharge quantity is more little.The length of tradition head and the tail head end is generally 35mm, and this makes that the office of dry-type transformer is high-volume very undesirable.
Summary of the invention
The technical assignment of the utility model is to above weak point, provides that a kind of production cost is low, easy installation and removal, the low office of dry type that partial discharge quantity is little put winding.
The utility model solves the technical scheme that its technical problem adopted: the low office of this dry type puts winding and comprises coil, first head end and tail head end; First head end is on coil top; Tail head end is in the coil bottom, and the length of first head end and tail head end all is 120mm.
The low office of the dry type of the utility model puts winding and compares with prior art, have reasonable in design, simple in structure, characteristics such as be easy to process, production cost is low, easy to operate, partial discharge quantity is little.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Accompanying drawing is the structural representation that winding is put in the low office of dry type.
Among the figure: 1, coil, 2, first head end, 3, tail head end.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described further.
Winding is put in the low office of the dry type of the utility model; Its structure comprises coil 1, first head end 2 and tail head end 3, and first head end 2 is on coil 1 top, and tail head end 3 is in coil 1 bottom; The length of first head end 2 and tail head end 3 all is 120mm; This makes creepage distance increase greatly, and partial discharge quantity reduces greatly, and the whole relatively transformer of manufacturing cost is constant basically.
It is very simple and convenient that its processing and fabricating of winding is put in the low office of the dry type of the utility model, and processing and fabricating gets final product shown in the by specification accompanying drawing.
Except that the described technical characterictic of specification, be the known technology of those skilled in the art.
Claims (1)
1. winding is put in the low office of dry type, comprises coil, first head end and tail head end, and first head end is on coil top, and tail head end is characterized in that in the coil bottom length of first head end and tail head end all is 120mm.
