遵义Power Transformer
产品描述
The classification of commonly used power transformers can be summarized as follows:
1. According to the number of phases:
(1) Single-phase power transformer: used for single-phase loads and three-phase power transformer groups.
(2) Three-phase power transformer: used to increase and decrease the voltage of a three-phase system.
2. According to the cooling method:
(1) Dry-type power transformer: It is cooled by air convection, and is generally used for small-capacity power transformers such as local lighting and electronic circuits.
(2) Oil-immersed power transformer: relying on oil as the cooling medium, such as oil-immersed natural cooling, oil-immersed air cooling, oil-immersed water cooling, forced oil circulation, etc.
3. Classified by purpose:
(1) Power transformer: used to increase and decrease the voltage of the power transmission and distribution system.
(2) Instrument transformers: such as voltage transformers, current transformers, measuring instruments and relay protection devices.
(3) Test transformer: It can generate high voltage and conduct high voltage test on electrical equipment.
(4) Special transformers: such as electric furnace transformers, rectifier transformers, adjustment transformers, etc.
