Abstract

The invention discloses a heat dissipation device for a dry-type transformer coil, which includes a transformer skeleton, a winding installation mechanism and a coil winding module are arranged on the outer periphery of the transformer skeleton, and a coil heat dissipation mechanism is arranged at the bottom of the transformer skeleton. The coil winding module includes several high-voltage side coil windings or low-voltage side coil windings, and the winding installation mechanism is used to nest and fix several high-voltage side coil windings or low-voltage side coil windings in the coil winding module An air duct for cooling the coil is reserved between any adjacent high-voltage side coil windings or low-voltage side coil windings, and the coil cooling mechanism is used to provide cooling wind force to each air duct for cooling the coil. The invention does not need to adjust the air duct specification for the capacity of the transformer, only needs to adjust the cooling wind force of the coil heat dissipation mechanism, and the splicing installation method facilitates subsequent cleaning and maintenance of the cooling channel without dismantling the coil winding.

Description

technical field [0001] The invention relates to the technical field of power transformation, in particular to a cooling device for a dry-type transformer coil. Background technique [0002] A transformer is a power device that uses the principle of electromagnetic induction to change the AC voltage. It can play the role of voltage conversion, current conversion, impedance conversion, and voltage stabilization in the circuit. It is widely used in many fields such as power supply, machinery manufacturing, metallurgy, and railways. ; [0003] With the increasingly fierce competition in the transformer industry, improving transformer production efficiency, reducing costs, improving product quality and paying attention to safety and stability have become important means to improve corporate competitiveness. The safety and stability of transformers is reflected in reducing the heat loss of transformer coils. For the current commonly used Coil cooling methods include an external b...
