Description
Technical field
The utility model relates to transformer coil winding equipment, specifically a kind of oil-immersed low voltage winding in transformers winding tool.
Background technology
The iron core of oil-immersed transformer is the triangle stereochemical structure being pieced together by three identical Winding iron core single frames of physical dimension, the core limb that is three dimensional wound core transformer is surrounding closing structure, and its coil can only coiling on the core limb of surrounding closure.At present, low-voltage coil coiling on oil-immersed transformer is mainly divided into two kinds of modes: a kind of is that winding former system is become to polylith watt shape sheet, again these watt of shape sheet is assembled into cartridge type integral body, be sleeved on two hemizonids and be connected on the coiling gear forming, under the rotation of coiling gear, drive coiling die body rotation coiling low-voltage coil; Another kind is to adopt certain thickness board rolls to make cylindrical structure, then is sleeved on two hemizonids and is connected on the coiling gear forming, and drives coiling die body rotation coiling low-voltage coil under the rotation of coiling gear.
The features such as coiling die body is detachable though above-mentioned the first winding method has, winding former body can be reused, finished product low-voltage coil inwall unobstructed (can form good heat exchange with transformer oil, thermal diffusivity is good); But it is complicated due to winding former body structure, have the defects such as moulding trouble, yielding, dismounting and positioning difficulty are large, and then coiling efficiency is low, poor reliability, practical not.Though above-mentioned the second winding method has effectively overcome the defect that the first winding method exists, but because its coiling die body is to adopt cardboard to roll the cartridge type overall structure forming, cannot split, must stay in finished product low-voltage coil, this blocks the inwall of the low-voltage coil die body that wound the line, the inwall of low-voltage coil can not form fully and contact with transformer oil, and then make the inwall of low-voltage coil not form good heat exchange with transformer oil, the poor radiation of low-voltage coil, in use poor reliability, also practical not.
In addition, because end and the distance between iron yoke of low-voltage coil are less, so low-voltage coil is in winding process, and lead-in wire is hidden in coil often, will draw after curved 90 ° of line Wei axial lead after coil winding again.This is for single wire, comparatively easy, but many electromagnetic wires and around in the situation that, there are many lead-in wires, if still according to the processing mode of drawing of single wire, many lead-in wires are directly tapped into row Wei simultaneously on coil curved, existing winding tool can not guarantee that every lead-in wire can both form effective impetus, thereby cannot guarantee that Yin Xian Wei is bent to position, and then affect insulation distance, also to carry out necessary repairing treatment to the overhang insulation of finished product coil simultaneously, increase workload, affect enterprises production efficiency; If the mode that employing is pulled out coil by the electromagnetic wire of many coiling moulding is entered line lead Wei crook reason, because the soft end of the coil yielding characteristic that insulate makes many coiling moulding electromagnetic wires that go between into merit Wei crook reason cannot effectively pack coil into, this not only makes the reliability of finished product low-voltage coil poor, and can increase workload equally, affect enterprises production efficiency.
Summary of the invention

Further, described frock also includes overhang insulation, this overhang insulation is divided into soft end insulation, the hard end insulation of coiling and finished product and firmly holds insulation, described soft end insulation and the hard end insulation of coiling are for being fixed on coiling die body at winding process, form respectively non-leading-out terminal insulation and leading-out terminal insulation, described finished product holds insulation firmly to hold insulation for replacing the coiling of semi-finished product low-voltage coil firmly.
Further, the rectangular triangle of the developed surface of insulation is held in described coiling firmly, has long straight flange, hypotenuse and short straight flange, and the long straight flange of the hard end insulation of coiling is towards coiling gear, and the hypotenuse of the hard end insulation of coiling is towards electromagnetic wire.
Further, described soft end insulation is to be sheared and formed by cardboard.
Further, described coiling die body is to be formed by impregnating resin curing fiberglass gridding coiled sheet system, rolls two end limits of crowding around and ties up fixing.
Further, described coiling die body is one deck at least.
Further, the central hole of described coiling gear has the cambered outwards boss of axle, and boss is used for being set with coiling die body.
Further, described coiling gear is two, two coiling gear intervals layouts, and the boss of two coiling gears is in opposite directions.
Further, described coiling gear is connected and is formed by two hemizonids.
The beneficial effects of the utility model are:
1. the waffle slab etc. with insulation rolls the coiling die body that forms cylindrical structure, this coiling die body integral body is loop configuration, can not be split, have simple in structure, with low cost, moulding is easy, location is convenient, the feature such as not yielding, after coiling without dismounting, directly stay in low-voltage coil, coiling efficiency is high, because it has some grid holes, these grid holes have formed oil duct, the low-voltage coil of finished product in use, transformer oil is formed fully and contacts with the inwall of low-voltage coil by oil duct, and then carry out fully, good heat exchange, the thermal diffusivity of low-voltage coil is good, reliability is high, practical,
2. by setting up interim coiling, firmly hold insulation to make electromagnetic wire smooth according to the angle of inclination of design, coiling fast, and the hard end insulation of utilization coiling reliable curved impetus of Biao Chu Wei on electromagnetic wire, the curved lead-in wire of handled easily Kong Jian Wei that after coiling completes, the hard end insulation of recycling coiling is taken out, going between successfully after processing holds insulation to replace the hard end insulation of coiling to be contained on low-voltage coil with finished product firmly, not only effectively making to go between can be curved at the Li Dian Wei of design, guarantee that Yin Xian Wei is bent to position, insulation distance is reliable, and firmly hold insulation without repairing treatment finished product, effectively alleviated workload, be conducive to significantly improve the production efficiency of enterprise, and then raising enterprise productivity effect, practical,
The features such as in sum, this frock has reasonable in design, simple in structure, with low cost, convenient formation, easy operating, coiling efficiency is high, lead-in wire is easy to draw, the heat radiation of finished product coil and good insulation preformance, reliability are high, practical.
