Abstract
The utility model relates to the technical field of transformer insulation, in particular to an end insulation structure of a transformer spiral coil. The end insulation structure of the transformer spiral coil comprises coil wires, insulation end rings and radial oil duct cushion blocks. The end insulation structure of the transformer spiral coil is characterized in that each insulation end ring is a horizontal circular ring, the radial oil duct cushion blocks are mounted between the insulation end rings and the spiral coil, and the contact surface of the radial oil duct cushion blocks and the spiral coil is set to be in a tilting shape which is matched with the gradient of the spiral coil. According to the end insulation structure of the transformer spiral coil, the insulation end rings are made to be flat, so that processing is facilitated, the matching position of the insulation end rings and the coil wires is levelled through the radial oil duct cushion blocks, the coil is evenly stressed in the pressing process, the number of radial oil ducts in the end of the coil is increased, the coil can be cooled conveniently, the overload capacity of a transformer is effectively improved, and the end insulation structure is suitable for being widely popularized and applied.
Description
(1) technical field
The utility model relates to transformer insulated technical field, particularly a kind of helical transformer coil overhang insulation structure.
(2) background technology
Present stage, the helical winding of 35～220kV level transformer, its insulating end ring is made tilted shape because of the inclination of coil, but coil inclined height is difficult for holding, the insulating end ring of making coordinates unbalanced with coil, discontinuity while causing coil press mounting, coil turn insulation is easily damaged, is unfavorable for the safe operation of transformer.
(3) summary of the invention
The utility model, in order to make up the deficiencies in the prior art, provides a kind of helical transformer coil overhang insulation structure simple in structure, easy to process.
The utility model is achieved by the following technical solution:
A kind of helical transformer coil overhang insulation structure, comprise winding wire, insulating end ring and width are to oil channel cushion block, it is characterized in that: helical winding is the individual layer cylindrical layer winding by winding wire coiling, insulating end ring is the horizontal circular ring that is provided with opening, the two ends up and down of helical winding are all provided with insulating end ring, winding wire is drawn through the opening on insulating end ring, between insulating end ring and helical winding, width is installed to oil channel cushion block, width is set to the tilted shape adapting with the gradient of helical winding to the contact-making surface of oil channel cushion block and helical winding.
The beneficial effects of the utility model are: the utility model is simple in structure, easy to process, the insulating end ring of helical transformer coil is made flat, be convenient to processing, with winding wire cooperation place by width to oil channel cushion block leveling, make coil stressed even in the time press-fiting, increased again the width of end winding to oil duct, be convenient to the heat radiation of coil, the capability of overload that effectively improves transformer, is suitable for wide popularization and application.
