Abstract
The utility model relates to a transformer, in particular to a structure of an oil duct for a transformer. The structure is characterized by comprising an upper cable paper tape and a lower cable paper taper, wherein a plurality of support strips are evenly distributed between the upper cable paper tape and the lower cable paper taper, and two ends of each support strip are respectively bonded on the upper cable paper tape and the lower cable paper taper. Therefore, the structure has the beneficial effects that the structure is simple in structure, smooth in oil duct, convenient to use and high in insulating property, thereby being widely popularized and applied.
Description
(1) technical field
The utility model relates to a kind of transformer, particularly a kind of transformer oil duct structure.
(2) background technology
Present stage; In superhigh pressure, extra-high voltage transformer in order to reduce to improve in the main insulating structure dielectric strength of transformer; Surfaces externally and internally place near the high pressure winding adopts corrugated board, though it can improve the field intensity allowable at this place, because corrugated board itself is made difficulty; Particularly length is high higher and be used in the corrugated board on the large-scale power transformer than length and width degree broad, rib, and manufacturing cost is higher; Add the restriction of the mechanical strength of itself, restricting its extensive employing always.
(3) summary of the invention
The utility model provides the transformer oil duct structure that a kind of oil circulation is smooth, insulation property are high in order to remedy the deficiency of prior art.
The utility model is realized through following technical scheme:
A kind of transformer oil duct structure, its special character is: comprise cable paper tape and following cable paper tape, upper and lower cable paper interband is evenly distributed with several stays, and the two ends of stay are bonded in respectively on the upper and lower cable paper tape.
Therefore, the beneficial effect of the utility model is: this transformer oil duct structure, and simple in structure, the oil circulation is smooth, easy to use, and insulation property are high, are suitable for wide popularization and application.
(4) description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 looks sketch map for the master of the utility model;
Fig. 2 is the schematic top plan view of the utility model.
Among the figure, cable paper tape on 1,2 times cable paper tapes, 3 stays.
(5) embodiment
Accompanying drawing is a kind of specific embodiment of the utility model.This embodiment comprises cable paper tape 1 and following cable paper tape 2, and upper and lower cable paper interband is evenly distributed with several stays 3, and the two ends of stay 3 are bonded in respectively on the upper and lower cable paper tape.
Adopt the transformer oil duct structure of the utility model, the two ends of stay 3 are bonded in respectively on the upper and lower cable paper tape, and the cable paper tape is not placed at the middle part of stay 3, has stopped the bonding between stay 3 usefulness glue and paper or the adjacent paper web; Be arranged near between the adjacent paper web in high-tension coil surfaces externally and internally place; Avoided the electric strength of glue phenomenon low and that cause electric field to concentrate owing to the formed bubble of glue in the bonding process own; Improved the electric strength of Transformer Winding middle part under the surge voltage effect, be mainly used in the transformer of the first head of 220kV level and above high pressure at winding middle part inlet wire.Therefore, the beneficial effect of the utility model is: this transformer oil duct structure, and simple in structure, the oil circulation is smooth, easy to use, and insulation property are high, are suitable for wide popularization and application.
Claims (1)
1. transformer oil duct structure, it is characterized in that: comprise cable paper tape (1) and following cable paper tape (2), upper and lower cable paper interband is evenly distributed with several stays (3), and the two ends of stay (3) are bonded in respectively on the upper and lower cable paper tape.
