The common commonly used transformer classification may induce as follows:
First, presses for several minute:
(1) single phase transformer: Uses in the single-phase load and three-phase 变压器组.
(2) three-phase transformer: Uses in the three-phase system to rise, to fall the voltage.
Second, according to coolant conditions minute:
(1) doing -like transformer: The dependence air convection carries on cooling, generally uses in the local lighting, the electronic circuit and so on the low-power transformer.
(2) oil bath type transformer: Depends upon the painter's shop cooling medium, like the oil bath self-cooling, the oil bath forced-air cooling, the oil bath water cooling, the force 油循�? and so on.
Third, according to use minute:
(1) power transformer: Uses in to lose the electrical power distribution system to rise, to fall the voltage.
(2) the meter uses the transformer: If the voltage transformer, the current transformer, use in the measuring instrument and 继电保护 the installment.
(3) testing transformer: Can produce the high pressure, carries on the high voltage test to the electrical equipment.
(4) special transformer: If electric stove transformer, rectification transformer, adjustment transformer and so on.
Fourth, according to winding form minute:
(1) double winding transformer: Uses in to connect in electrical power system two voltages rank.
(2) three windings transformers: Generally uses in the electrical power system region transformer substation, connects three voltages ranks.
(3) from pair converter: Uses in to connect the different voltage the electrical power system. Also may do after ordinary rises to press or to fall the transformer to use.
Fifth, according to ferrite core form minute:
(1) core type transformer: Uses in the high-pressured power transformer.
(2) shell type transformer: Uses in the big electric current special transformer, like electric stove transformer, welding transformer; Or uses in the electronic instrumentation and the television, the radio and so on the power transformer.
