Description
Technical Field
The utility model relates to a transformer manufacturing technology specifically is a low temperature rises transformer tank.
Background
Both the national standard of distribution transformers and the national network have temperature rise requirements, and the temperature rise requirements are mandatory. The original transformer oil tank structure has the following problems:
in order to ensure that the requirement of temperature rise is met, the volume of an oil tank needs to be increased, but the length and the width of the oil tank cannot be enlarged due to the influence of a field environment or a box transformer substation shell, so that the requirement of temperature rise is difficult to meet; meanwhile, the radiator structure is used for radiating, so that the manufacturing cost is increased.
SUMMERY OF THE UTILITY MODEL
Not enough such as rise to transformer temperature among the prior art, with high costs, the utility model aims to solve the problem that a low temperature that can reduce cost rises transformer tank is provided.
In order to solve the technical problem, the utility model discloses a technical scheme is:
the utility model relates to a low temperature rise transformer tank, including main tank and four auxiliary tanks, four auxiliary tanks are installed respectively in the four corners position of main tank, one side and the inside intercommunication of main tank of each auxiliary tank.
Each auxiliary tank is of a cuboid structure, one side of each auxiliary tank is arranged at the end part of the long shaft edge of the main oil tank, and the adjacent surface at one side of each auxiliary tank is flush with the short shaft edge of the main oil tank in the horizontal direction.
Short shaft corrugated sheets are respectively arranged on two short shaft edges in the horizontal direction formed by the main oil tank and the auxiliary tanks at the two ends; major axis corrugated sheets are respectively arranged in concave parts formed by two major axis sides and two end auxiliary tanks of the main oil tank; one side surface of the auxiliary box is connected with the short-shaft corrugated sheet.
The auxiliary tank is welded on the main oil tank, and the total size of the short shaft in the horizontal direction is smaller than or equal to the size of the main oil tank after the long shaft corrugated sheet is installed on the main oil tank.
The utility model has the following beneficial effects and advantages:
1. the utility model effectively reduces the temperature rise of the transformer under the condition that the total external dimension of the oil tank is not changed, and the temperature rise is reduced by 5-10k compared with the transformer without an auxiliary tank under the same external dimension;
2. the utility model discloses compare in the transformer with the temperature rise, length and width are little more than 300 mm.
Drawings
FIG. 1 is a front view of the transformer tank structure of the present invention;
fig. 2 is a top view of fig. 1.
The oil tank comprises an auxiliary tank 1, an oil tank body 2, a tank cover 3, a lifting plate 4, a tank bottom channel steel 5, a tank bottom 6, a tank wall 7, a long-axis corrugated sheet 8, a short-axis corrugated sheet 9, a high-voltage sleeve 10 and a low-voltage sleeve 11.
Detailed Description
The invention will be further explained with reference to the drawings attached to the specification.
As shown in fig. 1-2, the utility model relates to a low temperature rise transformer tank, including main tank 2 and four auxiliary tanks 1, four auxiliary tanks 10 are installed respectively in the four corners position of main tank 2, and one side and the inside intercommunication of main tank 2 of each auxiliary tank 1.
Each auxiliary tank 1 is of a cuboid structure, one side of each auxiliary tank is arranged at the end part of the long shaft side of the main oil tank 2, and the adjacent surface at one side of each auxiliary tank is flush with the short shaft side of the main oil tank 2 in the horizontal direction.
Short shaft corrugated sheets are respectively arranged on two short shaft sides in the horizontal direction formed by the main oil tank 2 and the auxiliary tanks 1 at the two ends; major axis corrugated sheets 8 are respectively arranged in concave parts formed by two major axis sides of the main oil tank 2 and the auxiliary tanks 1 at two ends; one side surface of the auxiliary box 1 is connected with the short-shaft corrugated sheet 9.
In the embodiment, four auxiliary tanks 1 are welded at four corners of a main oil tank 2, one surface of each auxiliary tank 1 is arranged at one end of the edge of the main oil tank 2 in the long axis direction, the surface is communicated with the main oil tank 2, the four auxiliary tanks 1 form an I-shaped structure in the overlooking direction after being welded, long axis corrugated sheets 8 are arranged on concave parts at two sides of the I-shaped structure, and short axis corrugated sheets 9 are arranged at two ends of the I-shaped structure; the height of the auxiliary tank 1 is greater than the height of the short-axis corrugated sheet 9.
One side surface of the auxiliary tank 1 is connected with the short-shaft corrugated sheet 9, so that the total length of the short-shaft corrugated sheet 9 can extend out of the main oil tank 2, and the effect of enlarging the heat dissipation area is achieved. After the auxiliary tank 1 is welded on the main oil tank 2, the total size of the short shaft in the horizontal direction is smaller than or equal to the size of the main oil tank 2 after the long shaft corrugated sheet 8 is installed, and the shape size is guaranteed to be unchanged.
The oil tank cover 3 is arranged on the upper part of the main oil tank 2, and the high-voltage sleeve 10 and the low-voltage sleeve 11 are arranged on the oil tank cover 3. Four lifting plates 4 are arranged on the oil tank cover 3 for lifting.
The tank wall 7 of the main oil tank 2 is arranged on the tank bottom 6 and welded with the long-axis corrugated sheet 8 and the short-axis corrugated sheet 9 to form an oil tank body.
The long-axis corrugated sheet 8 and the short-axis corrugated sheet 9 are used for heat dissipation of the transformer, and the temperature rise of the transformer can be effectively reduced by increasing the surface area of the transformer.
