Abstract
The utility model discloses a fixing structure for high-voltage leads of oil-immersed distribution transformers. The fixing structure is characterized in that high-voltage head leads are bound with tapping leads of coils by thermal shrinkage straps, the tapping leads are tightened with one another by thermal shrinkage straps and are fixedly and firmly bent, and an insulating paperboard with the thickness of 1 millimeter is additionally arranged between each tapping lead and a clamp, so that an insulation reinforcing effect can be realized; tapping leads of a switch are skinned according to measured sizes, and insulating crepe paper tubes sleeve the tapping leads of the switch and slide down after the tapping leads of the switch are welded with the tapping leads of the coils, so that exposed welded positions can be completely packaged. The fixing structure has the advantages that raw materials can be saved, the fixing structure is simple and is low in production cost, workers can conveniently operate the fixing structure, and accordingly the production efficiency can be improved; lead supports do not need to be welded on the clamp, welded spots of the clamp are reduced, and accordingly the clamp is attractive.
Description
Technical field
The utility model belongs to field transformer, relates to a kind of fixed structure of oil immersion-type distribution transformer high-voltage connection.
Background technology
Present stage, the high-voltage connection of oil-filled transformer steps up the first head of high pressure and tap lead with wood clamp part, uses the cost of wood clamp part higher, workman's inconvenient operation, and workman's the amount of labour is large, and production efficiency is low; Switch leads and coil tap lead weld are in layer wrapped up with crimped paper, increase workman's working time, cause production efficiency low.Folder welding lead support, solder joint is many, and outward appearance is plain.
Summary of the invention
The utility model is in order to make up the deficiencies in the prior art, and a kind of fixed structure of simple in structure, easy to operate, the oil immersion-type distribution transformer high-voltage connection of enhancing productivity is provided.
The utility model is achieved by the following technical solution:
The fixed structure of oil immersion-type distribution transformer high-voltage connection of the present utility model, it is characterized in that: iron core and folder are installed in transformer-cabinet, on iron core, cover has coil, transformer box cover bottom connects bushing and without field switch, bushing connects the first head lead-in wire of downward high pressure, with pyrocondensation belt by together with the tap lead colligation of first high pressure head lead-in wire and coil, and also tie tight with pyrocondensation belt between tap lead and tap lead, tap lead is bended fixed, between tap lead and folder, install the insulating board of 11 millimeters thick additional, play reinforced insulation, the tap lead of switch strips off the skin according to measured size, puts insulation wrinkle paper tube, after the tap lead of switch and the tap lead of coil weld together, slides insulation wrinkle paper tube, and exposed weld is set with completely.
The beneficial effects of the utility model are, 1, do not re-use wood clamp part and clamp the first head of high pressure and tap lead, raw material are saved, structure is simpler, and production cost is lower, and workman is more convenient to operate, improve production efficiency, welding lead support no longer on folder has reduced the solder joint of folder simultaneously, makes the outward appearance of folder more beautiful.2, with insulation crimped paper pipe box dress switch leads and coil tap lead weld, reduce workman's working time, enhance productivity.
