Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of transformers, in particular to a double-split oil-immersed transformer. BACKGROUND

[0002] The double-split oil-immersed transformer is a special power transformer, which is designed and constructed to meet the requirements of specific electrical systems. It is mainly used in situations where high short-circuit impedance or the need to limit short-circuit current is required. This type of transformer is very useful in large industrial facilities, power stations, and complex power distribution networks. The existing transformers generally rely on heat sinks to assist in heat dissipation, or use external integrated heat dissipation mechanisms. The existing external integrated heat dissipation mechanisms are generally water-cooled or air-cooled for cooling. Whether it is a heat sink or an external heat dissipation mechanism, when fixed to the outside of the transformer, it cannot be quickly disassembled. Generally, the heat dissipation mechanism needs to be replaced and maintained after it fails. During the maintenance process, if it is in high-temperature weather, the transformer without the assistance of the heat dissipation mechanism will not be able to operate normally and will have to be shut down. This situation will directly affect the operation of the entire power system and is fixedly set, which makes it impossible to adjust the heat dissipation mechanism according to the operating state of the transformer, resulting in poor heat dissipation effect.
