Product introduction
1000kVA and above Oil Immersed Transformers must be equipped with outdoor signal thermometers and can be connected to remote signals. Oil immersed transformers of 800kVA and above shall be equipped with gas relay and pressure protection device. Oil immersed transformers of 800kVA and below can also be equipped with gas relay according to the use requirements and through consultation with the manufacturer. Dry type transformers shall be equipped with temperature measuring devices according to the manufacturer's regulations, generally 630kVA and above transformers.
The products are classified according to the phase number of a single transformer, which can be divided into three-phase transformers and single-phase transformers. In three-phase power systems, three-phase transformers are generally used. When the capacity is too large and limited by transportation conditions, three single-phase transformers can also be used in three-phase power systems to form transformer banks.
Winding division
It can be divided into two winding transformers and three winding transformers. Generally, transformers are double winding transformers, that is, there are two windings on the iron core, one is the primary winding and the other is the secondary winding. The three winding transformer is a transformer with large capacity (above 5600 KVA), which is used to connect three different voltage transmission lines. In special cases, there are also Satons transformers with more windings. Structural classification It can be divided into core transformer and shell transformer. If the winding is wrapped around the iron core, it is an iron core transformer; If the iron core is wrapped around the winding, it is a shell type transformer. However, they are slightly different in structure and have no essential difference in principle. All power transformers are iron core type. The transformer is mainly composed of iron core, winding, oil tank, conservator, insulating sleeve, tap changer, gas relay, etc.
