Product introduction The Oil Immersed Transformer is a high-performance transformer with more reasonable structure and better performance. The iron core is made of electrical steel strip, and the laminations at all levels are prepared in order...
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.
According to the phase number of a single transformer, it can be divided into three-phase transformer and single-phase transformer. 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 to form a transformer bank in three-phase power systems.
According to the number of windings, 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 transformers with more windings.
According to the structure, it can be divided into core type transformer and shell type 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.
According to insulation and cooling conditions, it can be divided into Oil Immersed Transformer and Dry Type Transformer. In order to strengthen the insulation and cooling conditions, the core and winding of the transformer are immersed together in the oil tank filled with transformer oil. In special cases, such as street lamps and mine lighting, dry-type transformers are also used.
In addition, there are various special transformers for special purposes. For example, high-voltage transformer for test, transformer for electric furnace, transformer for electric welding and transformer for SCR circuit, voltage transformer and current transformer for measuring instrument.
