Magnetic flux leakage telescopic circulating type heat dissipation oil tank of single-phase oil-immersed transformer

Abstract

The invention discloses a magnetic flux leakage telescopic circulation type heat dissipation oil tank of a single-phase oil-immersed transformer, and the oil tank comprises a tank body; a plurality offixing blocks are symmetrically installed on the inner wall of the tank body, piston cylinders are installed on the portions, located on the upper side and the lower side of each fixing block, of theinner wall of the tank body, and a magnetostriction rod is inserted into each fixing block; the two ends of each magnetostriction rod extend into the two corresponding piston cylinders respectively and are provided with piston plates, three-way one-way liquid discharging pipes are installed at the upper ends of the multiple piston cylinders on the upper layer, and three-way one-way liquid pumpingpipes are installed at the lower ends of the multiple piston cylinders on the lower layer. Magnetic flux leakage of the transformer is directly converted into telescopic mechanical energy through themagnetostriction rod to push the piston plate piston to move, three-dimensional circulating heat dissipation is achieved through a three-way one-way liquid discharging pipe, a three-way one-way liquid pumping pipe and hollow cooling fins, the circulating speed can be automatically adjusted along with increase of loads, the heat dissipation reliability is improved; the structure is simple, and thetransformer volume is unaltered.

Description

technical field [0001] The invention relates to the field of transformers, in particular to a single-phase oil-immersed transformer magnetic leakage telescopic circulation type cooling oil tank. Background technique [0002] Single-phase transformers are widely used in various residential areas and villages as one of the commonly used power devices for residential electricity consumption. Oil-type single-phase transformers are especially common in rural areas, and because the power supply in rural areas is weaker than that in urban areas, and the peak power consumption in rural areas is relatively concentrated. Therefore, the transformer needs to run at high load at certain moments. [0003] The existing heat dissipation method for transformers resistant to high-load operation adopts external air-cooled heat dissipation, and an air-cooled box is added outside the transformer to speed up the heat transfer speed, but this method will not only increase the volume and structure ...
