Embodiment 1

[0025] The heat sink structure of the transformer, such as figure 1 As shown in the top view, a first groove 2 is provided at one end of the outer side of the heat transfer oil chamber 1, and a second groove 6 is provided at the other end. The openings of the first groove 2 and the second groove 6 are mutually Orientation, a rotating shaft 3 is also provided on the first groove 1, an elastic member 4 (spring) is also provided inside the first groove 2, and a cooling fin 5 is also included, and one end of the cooling fin 5 is arranged in the first concave In the open opening of the slot 2, it is tightened by a spring so that the other end of the cooling fin 5 is located inside the second slot 6.

[0026] When the heat sink 5 needs to be disassembled, such as figure 2 As shown, the cooling fin 5 is pressed to the left so that the spring is tightened, and then the first groove 2 is rotated to rotate the cooling fin 5 to an angle, so that the cooling fin 5 can be pulled out conv...

Embodiment 2

[0029] The heat transfer oil is made of the following components by weight: 10 parts of sunflower oil, base oil (the kinematic viscosity at 100°C is 20-35mm 2 / s mineral oil) 90 parts, 2-aminoethyl heptadecenyl imidazoline 5 parts, glyceryl triacetate 5 parts, 2,6-tert-butyl p-cresol 2 parts, rust inhibitor dodecenyl 3 parts of succinic acid, 3 parts of surfactant isomeric tridecanol polyoxyethylene ether, 3 parts of dispersant polyalkenyl succinimide, 3 parts of antioxidant thiophosphobutyloctyl zinc salt; the preparation method is , mix each component evenly, heat up to 50-60°C, stir, and let cool.

Abstract

The invention relates to a heat sink structure of a transformer, which belongs to the technical field of electric equipment. One end of the outer side of the heat conduction oil chamber is provided with a first groove, and the other end is provided with a second groove, the openings of the first groove and the second groove are facing each other, and there is also a groove on the first groove The rotating shaft is also provided with an elastic member inside the first groove, and also includes a heat sink, one end of the heat sink is arranged in the opening of the first groove, and is tightened by a spring, so that the other end of the heat sink is positioned at the second Inside the groove. The cooling fin structure provided by the invention is easy to disassemble, has good heat transfer effect and is easy to clean.

Description

technical field [0001] The invention relates to an easily disassembled heat sink structure of a transformer, which belongs to the technical field of electric equipment. Background technique [0002] Transformer is a kind of voltage transformation equipment used in power transmission system, which plays a very important role in power grid system. When the transformer is running, the internal coil will generate a lot of heat. If the heat generated by the coil cannot be dissipated in time, it will affect the normal use of the transformer, and even seriously affect the entire power transmission system; therefore, the current transformers are all There is an oil tank, and the transformer oil is stored in the oil tank. Through the circulation of the transformer oil in the transformer, the heat generated by the coil during the operation of the transformer is absorbed, and then the heat absorbed by the transformer oil is dissipated to the outside through the flat cooling box set on ...
