The difference between fully sealed three-phase oil-immersed transformer with chip radiator and flat
Everyone knows that a fully sealed three-phase oil-immersed transformer will generate a large amount of heat during operation. In order to ensure the safety of the transformer, improve the efficiency of the transformer and reduce the loss, the oil-immersed transformer is often equipped with a finned radiator. There are two common types of radiators, chip radiators and flat tube radiators.
Chip radiator: Suitable for three-phase oil-immersed transformers below 6300KVA. When the chip radiator is added with a fan, it can be used for fully sealed three-phase transformers above 6300KVA. Structural features: After stamping two symmetrical corrugated plates from 1mm steel plate, they are seam welded to each other to form a heat sink. The heat sinks are arranged one behind the other and welded to the oil guiding tube to form a heat sink. The utility model has the advantages of light weight, low oil consumption, and can be directly welded to the wall of the mailbox to become a non-removable co-type, and can also be connected to the oil in the mailbox through the oil inlet pipe and the travel pipe to form a detachable cooperative radiator. Adding a fan to the side or bottom becomes a blower type radiator, which improves cooling capacity. The expandable chip radiator can be used in a fully sealed three-phase dry type transformer.
Flat tube radiator: It is suitable for three-phase transformers below 6300KVA. When the flat tube radiator is added with a fan, it can be used for three-phase transformers above 8000~40000KVA.
Structural features: 100 flat tubes are welded to the upper and lower oil collecting boxes to form a flat tube radiator. After the oil inlet pipe and the oil outlet pipe are connected with the oil inside the fuel tank, a fan is arranged in the middle space of the flat pipe arrangement structure. Become a blower radiator to increase cooling capacity.
