Abstract
The utility model discloses a box cover panel structure of a transformer, which is characterized in that the four peripheral edges of a box cover made of steel plates have downward flangings. The box cover panel structure has simple structure, low cost, high productivity and attractive appearance, utilizes the downward flangings of the four edges of the box cover to cover horizontal outer edges and sealing rubber strips of an upper opening of the box edges, effectively avoids ultraviolet ray from irradiating and ageing, improves the sealing performance, has good protecting effect and can be applicable to medium and small-sized transformers.
Description
Technical field
The utility model relates to a kind of transformer, specifically is a kind of novel transformer case lid panel construction with flanging.
Background technology
Present transformer tank cover panel, employing be a kind of plate armature, directly by a steel plate in the cutting of numerical control or automatic gas cutting machine, make through boring, leveling.The steel plate case lid directly covers along parallel with case, and case lid, case are along connecting by fastening bolt, and sealing joint strip places between case lid and the case edge, does not ooze, does not leak with assurance.Since the case lid panel directly with case along parallel connection, sealing joint strip easily quickens ageing of rubber because of sunlight, ultraviolet direct irradiation, influences its sealing property and useful life, causes transformer to be prone to the infiltration phenomenon.
The utility model content
The purpose of this utility model is to provide a kind of transformer tank cover panel structure at the deficiencies in the prior art, can hide transformer tank effectively along last sealing joint strip, avoid sunlight, ultraviolet direct irradiation, improved the sealing property of sealing joint strip, prevent that the infiltration phenomenon from appearring in transformer.
The technical scheme that the utility model adopted:
A kind of transformer tank cover panel structure, comprise the case lid panel, the surrounding that it is characterized in that the case lid panel made at steel plate is provided with downward flanging, utilize the flanging of case lid to cover case along horizontal outer suitable for reading, both improved the intensity of case lid, and prevented from when bolt is strained, to produce distortion around the case lid, and made the sealing joint strip that places between case lid and the horizontal outer of casing not be subjected to sunlight, ultraviolet direct irradiation simultaneously, prevent that sealing joint strip is aging, has improved sealing property.
The utility model is simple in structure, and cost is low, productivity ratio is high, good looking appearance, utilize the downward flanging in four limits of case lid to cover case, avoid ultraviolet irradiation aging effectively, improved sealing property along horizontal outer and sealing joint strip suitable for reading, protection effect is good, applicable to middle-size and small-size transformer.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, case lid panel; 2, flanging.
Embodiment
In the structure shown in the figure, the utility model is cut in numerical control or automatic gas cutting machine by a steel plate, the edge that has flanging around cutting out, be placed on then on the lathe of automatic bender, the edge is carried out four springs foldings, be made into transformer case lid with case lid panel 1 and downward flanging 2.During use, sealing joint strip is placed on the horizontal outer of casing, then case lid is directly covered transformer tank along horizontal outer suitable for reading, case lid, case are along connecting by fastening bolt, flanging 2 can hide transformer tank along last sealing joint strip, avoids ultraviolet irradiation aging fully, has improved sealing property.
