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 relays and pressure protection devices. Oil-immersed transformers of 800kVA and below can also be equipped with gas relays 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. Double winding transformer is a common type of transformer, characterized by two windings on the iron core, namely the primary winding and the secondary winding. A three winding transformer is a type of high capacity (over 5600 kVA) transformer used to connect three transmission lines with different voltages. In special cases, there are also Satons transformers with more windings.

Structural classification

It can be divided into the core transformer and the 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 the iron core, winding, oil tank, conservator, insulating sleeve, tap changer, gas relay, etc.
