Description

Technical Field

[0001] The utility model relates to the technical field of box-type transformer substations, and in particular to a prefabricated transformer substation lead-in duct type air duct system structure. Background Art

[0002] During transformer operation, the primary heat sources are the iron core and high- and low-voltage coils. The heat dissipation of the iron core is primarily due to no-load losses, while the heat dissipation of the coils is primarily due to internal resistance current heat losses. During actual transformer operation, coil leakage flux generates eddy currents and stray losses, which are known as parasitic losses. Transformer load losses include both resistance losses and parasitic losses. Consequently, significant heat losses are generated during transformer operation, impacting both operational stability and service life. Addressing these issues is crucial. Utility Model Content
