Embodiment Construction

[0027] The specific embodiments provided by the present invention will be described in detail below in conjunction with the accompanying drawings.

[0028] Such as Figure 1-6 As shown, a new transformer oil baffle structure suitable for special environments, the coil of the transformer is a wire cake 4 type structure, the oil baffle structure includes an inner oil baffle 9 and an outer oil baffle 10, The inner oil baffle 9 and the outer oil baffle 10 have the same structure, both of which are U-shaped annular structures folded from corrugated cardboard. The oil plate 10 is on the outside of the wire cake 4 (that is, away from the iron core side), and the U-shaped openings are all facing the wire cake 4 to clamp the wire cake 4.

[0029] Such as figure 1 As shown, the coil of the transformer is divided into multiple oil areas from top to bottom, each oil area includes a multi-layer wire cake 4, an inner oil baffle plate 9 is placed at the head and end of the coil, and the o...

Abstract

The invention provides a novel transformer oil baffle plate structure suitable for a special environment. A coil of the transformer is of a wire cake type structure, the oil baffle plate structure comprises an inner oil baffle plate and an outer oil baffle plate, the inner oil baffle plate and the outer oil baffle plate are the same in structure and are both of an annular structure with a U-shapedsection formed by folding corrugated boards, the inner oil baffle plate is arranged at the inner side of a wire cake, and the outer oil baffle plate is arranged at the outer side of the wire cake, and the U-shaped openings face the wire cake to clamp the wire cake. A coil of the transformer is divided into a plurality of oil areas from top to bottom, each oil area comprises multiple layers of wire cakes, the head end and the tail end of the coil are each provided with the inner oil baffle plate, the inner oil baffle plates or the outer oil baffle plates are arranged at the oil area division positions in the middle of the coil, and the inner oil baffle plates and the outer oil baffle plates are arranged in a staggered mode. The temperature rise of the transformer coil is reduced, the transformer cost is reduced to the maximum extent, and the design requirement of high-temperature environment temperature is met.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to a novel transformer oil baffle structure suitable for special environments. Background technique [0002] Africa is known as the tropical continent, and its climate is characterized by high temperature, little rain and dryness. Over 95% of the continent has an average annual temperature above 20°C, and the highest ambient temperature is as high as 58.8°C. This requires us not to base our design on the current domestic ambient temperature of 20°C and the highest ambient temperature of 40°C when designing transformers for African projects. In order to ensure the safe operation of the transformer, it is necessary to reduce the temperature rise of the transformer coil. Therefore, we have designed a new oil baffle structure to reduce the temperature rise of the transformer coil and reduce the cost of the transformer to the greatest extent. [0003] At present, the oil baffle st...
