Thermodynamic snow accumulation prevention type outdoor transformer

Abstract

The invention discloses a thermodynamic snow accumulation prevention type outdoor transformer, belongs to the field of transformers, and particularly relates to the thermodynamic snow accumulation prevention type outdoor transformer. An expansion snow melting column in a rod-type closed chain is heated to expand by utilizing heat generated during operation of a transformer body, and under the sizelimitation of non-equidistant chutes, the whole rod-type closed chain is driven to rotate in a loop; on one hand, the expansion snow melting column expanded after being heated moves to the outside tosweep and melt ice and snow at the upper end of a protective shell, and on the other hand, the expansion snow melting column restored to the original state after being shrunk in the outside moves tothe interiors of the non-equidistant chutes to be expanded again after being heated; and therefore, continuous circulating movement of the whole rod-type closed chain is achieved, ice and snow at theupper end of the protective shell are circularly removed and melted in the loop moving process, the situation that the upper end of the protective shell is covered with snow and ice is greatly reduced, and normal use of the transformer body is effectively guaranteed.

Description

technical field [0001] The invention relates to the field of transformers, and more particularly, to a thermal snow-proof outdoor transformer. Background technique [0002] A transformer is a device that converts alternating current, alternating current, and characteristic impedance. When there is an AC circuit in the primary electromagnetic coil, the iron core (or iron core) will cause the AC magnetic flux to be communicated, thereby causing the working voltage (or current amount) in the secondary electromagnetic coil. Classified according to main purposes: power engineering transformers, special-purpose transformers (furnace wall transformers, rectifier transformers, DC experimental transformers, voltage regulators, mine-proof transformers, etc.). [0003] When the transformer is used outdoors, due to the large changes in environmental factors, it must have the requirements of good heat dissipation, waterproof, high temperature resistance, cold resistance, and UV resistan...

AI Technical Summary

Problems solved by technology

[0003] When the transformer is used outdoors, due to the great changes in environmental factors, it must have the requirements of good heat dissipation, waterproof, high temperature resistance, cold resistance, and UV resistance. It will increase the load of the transformer and accelerate the corrosion of the transformer. Long-term ice and snow will easily cause the inside of the transformer to be damp. Therefore, the phenomenon of snow and ice will seriously affect the use of the transformer.
