Abstract
The utility model relates to a high-insulation level mutual inductor framework made of nylon. The two ends and the middle part of a primary framework are provided with projections, and the middle parts of the projects are provided with grooves. With the structure, the mutual inductor framework increases the creep distance and has high insulation level.
Description
Technical field
The utility model relates to a kind of instrument transformer skeleton of high insulation level.
Background technology
For a long time; The tradition instrument transformer skeleton all adopt cylinder frame made of paper, on the skeleton behind secondary coil around multilayer PMP composite-insulating paper as main insulation, again around primary winding; One, two coil is wound on the cylinder made of paper simultaneously, yet there is following problem in cylinder frame made of paper always:
Behind the cylinder frame coiling made of paper, behind carrying and dress mould, make the coil move left and right easily, make creepage distance minimizing between the secondary, it is defective to insulate;
Easy deformation after the cylinder frame coiling made of paper, assembling difficulty when iron core is put into;
Individual skill when creepage distance relies on the operator to wind the line between the distance of the left and right sides line parlor of primary winding and the secondary at two ends guarantees to have randomness.
The utility model content
For solving the long-standing problem of cylinder frame made of paper, the utility model provides a kind of instrument transformer skeleton of high insulation level.The utility model is realized through following technical scheme:
Framework material is a nylon; Design is protruding in the middle of the primary winding skeleton in skeleton; Separating with part about the primary line bag of this coil, is frame design secondary skeleton and a skeleton, is provided with convexity in the two ends and the centre of a skeleton and is provided with fluting in the convexity centre.
The beneficial effect of the utility model:
The randomness of the individual skill when having solved creepage distance between the secondary of cylinder frame made of paper and relying on the operator to wind the line; Guaranteed the reliability of creepage distance; This skeleton can obviously improve the product insulation property, and the insulating capacity of product is reached more than the 60kV, is convenient to coil winding and assembling; Can improve the circulation of transformer oil to the oil immersed type batch meter, delay the transformer oil deterioration.
Description of drawings
Fig. 1 is the utility model structural representation Fig. 1, is skeleton, 2, be protruding, 3, be fluting.
Embodiment
Framework material is a nylon, is provided with convexity and in the middle of protruding, is provided with fluting in the two ends and the centre of a skeleton.
Claims (1)
1. the instrument transformer skeleton of a high insulation level is characterized in that framework material is a nylon, is provided with convexity and in the middle of protruding, is provided with fluting in the two ends and the centre of a skeleton.
