Ensure the power safety of users and ensure that the voltage can meet the power needs of different electric appliances
1.Change the voltage so that the high voltage is reduced or the low voltage is increased. Transformer is a device that transforms AC voltage, AC current and impedance. When AC current is connected in the primary coil, AC magnetic flux will be generated in the iron core (or magnetic core), causing voltage (or current) to be induced in the secondary coil.
2.What matters need to be paid attention to in the installation of transformer? The convenience of operation, maintenance and transportation shall be considered in the installation of transformer. The nameplate items of transformer shall be complete, and the installation position shall be convenient for live patrol. The installation of transformer shall consider that it can check the oil color, oil level, upper oil level temperature and gas relay of transformer.
3.What kinds of transformers are there? Dry type transformer: relying on air convection for natural cooling or increased fan cooling, which is mostly used for small capacity transformers such as high-rise buildings, high-speed toll stations, local lighting and electronic circuits. Oil immersed transformer: relying on oil as cooling medium, such as oil immersed self cooling, oil immersed air cooling, oil immersed water cooling, forced oil circulation, etc.
