Abstract

The invention discloses a cooling device for an immersion type transformer. The cooling device comprises a barrel-shaped transformer box body, an iron core, a coil and scattered pieces. The barrel-shaped transformer box body is provided with two opposite side walls and two opposite end walls. The top corners of the inner walls of the end walls and the inner walls of the adjacent side walls of the barrel-shaped transformer box body are provided with bearing angle steel. The inner surfaces of the bearing angle steel installed on the top corners of the inner walls of the end walls and the inner walls of the adjacent side walls are fixedly connected with cooling liquid guide devices respectively. Cooling liquid in the scattered pieces form relatively isolated space with the coil, iron core and the other components in the barrel-shaped transformer box body, the turbulence phenomenon is avoided in the convection process of the immersion type transformer cooling liquid, the convection and cooling effect of the immersion type transformer cooling liquid is improved, and stable running of the immersion type transformer is ensured.

Description

technical field [0001] The invention belongs to a component product of a liquid-immersed transformer, in particular to a cooling device for a liquid-immersed transformer. Background technique [0002] At present, the existing liquid-immersed transformer is mainly composed of a barrel-shaped transformer box, iron core, coil, cooling liquid, and chips. When the liquid-immersed transformer is running, a part of the electromagnetic energy is converted into heat, which is dissipated from the hottest point of the coil and iron core to the surface of the component by conduction, and the heat is dissipated from the surface of the component to the cooling liquid, which is realized by convection. Cooling of components such as coils and cores. However, the existing liquid-immersed transformer coolant is prone to turbulence or turbulent flow during the convection process, which sometimes causes unstable cooling of components such as coils and iron cores, and the cooling effect of the c...
