Abstract
The utility model discloses an oil duct of transformer, including the insulating board strip, even interval is provided with a plurality of cross -over blocks on the insulating board strip, the both sides fixedly connected with insulating pad at every cross -over block both ends, and cross -over block and insulating pad pass through the adhesive to be fixed on the insulating board strip, the oil duct skin is equipped with the pyrocondensation insulated tape, increases structure firmness. The utility model discloses simple structure, safe and reliable practices thrift the cost, and insulating properties is good, has improved the life of oil duct, reduces the noise of transformer.
Description
Technical field
This utility model relates to electrical equipment technical field, is specifically related to a kind of transformer oil passage.
Background technology
The oil duct unshakable in one's determination of current power transformer mainly adopts the fixing means of sticky pad block on lamination, the processing of this fixed structure and bonding workload are big, the reliability that is adhesively fixed is not high, add the work workload of workman, owing to the bonding iron core oil channel cushion block that loosely easily causes comes off with lamination in iron coring vibration process, block oil duct unshakable in one's determination, between lamination, cause that transformer body noise increases owing to non iron-core oil channel cushion block supports.
Utility model content
For making up the deficiencies in the prior art, this utility model provides transformer oil passage a kind of firm in structure, that noise is little.
This utility model is achieved by the following technical solution:
A kind of transformer oil passage, it is characterized in that and includes insulating paper lath, and on described insulating paper lath, uniform intervals is provided with some cross-over blocks, and the both sides at each cross-over block two ends are fixedly connected with insulation spacer；Described cross-over block and insulation spacer are fixed on insulating paper lath by binding agent；Oil duct outer layer is provided with pyrocondensation insulating tape, increases structural integrity.
Transformer oil passage of the present utility model, the height of described insulation spacer is 0.1-1mm, and cross-over block height is 3-5mm, and the existence of insulation spacer will not block oil stream.
The beneficial effects of the utility model are: this utility model simple in construction, safe and reliable, save cost, good insulation preformance, improve the service life of oil duct, reduce the noise of transformator.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
Accompanying drawing 2 is the structural representation of this utility model embodiment.
In figure, 1 insulating paper lath, 2 cross-over blocks, 3 insulation spacers, 4 pyrocondensation insulating tapes.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail.
Accompanying drawing is a kind of detailed description of the invention of the present utility model.This embodiment includes insulating paper lath 1, and on described insulating paper lath 1, uniform intervals is provided with some cross-over blocks 2, and the both sides at each cross-over block 2 two ends are fixedly connected with insulation spacer 3；Described cross-over block 2 and insulation spacer 3 are fixed on insulating paper lath 1 by binding agent；Cross-over block 2 interleaved arrangement on adjacent two insulating paper laths 1；Oil duct outer layer is provided with pyrocondensation insulating tape 4, and the height of the insulation spacer 3 of the present embodiment is 0.5mm, and cross-over block 2 is highly 4mm.
The insulation spacer 3 of the present embodiment both can increase the bonding strength between cross-over block 2 and insulating paper lath 1, simultaneously again without influence on oil stream, keeps passage smooth and easy, and oil duct is strengthened fastening by pyrocondensation insulating tape 4, reduces transformer noise.
