Dry-type Transformer-power Transformer
Dry Type Transformer refers to a kind of power transformer whose core and winding are not immersed in insulating oil and adopts natural cooling or air cooling. As a late-emerging power distribution equipment, it has been widely used in power transmission and transformation systems in factory workshops, high-rise buildings, commercial centers, airports, docks, subways, oil platforms and other places, and can be combined with switch cabinets to form a compact complete set of substations.
At present, most of my country's dry-type power transformers are three-phase solid-molded SC series, such as: SCB9 series three-phase winding transformers, SCB10 series three-phase foil transformers SCB9 series three-phase foil transformers. Its voltage level is generally in the range of 6-35KV, and the maximum capacity can reach 25MVA. For dry-type transformers, do you want to know more? The following Xianji.com editor will introduce in detail the structural form, cooling method, type, and advantages of dry-type transformers compared with oil-immersed transformers? Installation and debugging, how to judge faults from sound, noise caused by external structure and solutions, and selection points. Let's take a look!
