Rollen för olje-nedsänkta transformatorer i transformatorstation
"Box-type transformer" is the abbreviation of box-type substation, also known as standby substation. High-voltage switch gear, distribution transformers, low-voltage power distribution devices. The factory is a prefabricated indoor and outdoor small power distribution equipment, which is configured according to a certain wiring scheme. The transformer's step-down and low-voltage power distribution functions are organically combined, and are set in terms of moisture-proof, rust-proof, dust-proof, rat-proof, fire-proof, and anti-theft. The insulated, fully enclosed, mobile steel structure box is especially suitable for the construction and transformation of urban power grids. It is a new substation emerging after civil substations. Box-type substations are suitable for mines, factories, enterprises, natural gas fields and wind power stations.
Instead of the existing civil power distribution room and power distribution station, it becomes a new type of substation equipment. On the other hand, a transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. The main parts are the coil, the secondary coil and the iron core, that is, the magnetic core. In electrical equipment and wireless circuits, upper and lower voltages, corresponding impedances, safety insulation, etc. are very common. The main functions are voltage transformation, current transformation, impedance transformation, insulation, voltage adjustment (magnetic saturation transformer), etc. According to the variety of applied transformers, it can be divided into distribution transformers, power transformers, etc. Transformers, fully sealed transformers, control transformers, dry-type transformers, waterproof transformers, single-phase transformers, three-phase transformers, rectifier transformers, etc.
Transformatorn av -typ koncentrerar endast transformatorn och dess höjd-,-lågspänningsutrustning för in- och utgångsledning i en låda, och tar inte hänsyn till investeringen i byggnader som kraftdistributionsrum. Transformatorstationen av box-typ integrerar primär och sekundär utrustning såsom strömbrytare, samlingsskenor, sekundärutrustning (skydd, mätare, etc.), DC-system, etc. i en låda. Den ena är att minska golvytan och spara markresurser, och den andra är att spara investeringar i byggnader som eldistributionsrum. Generellt sett är transformatorer inte koncentrerade i transformatorstationer av-lådtyp. Därför är transformatorn av-typ en hög-växlingsenhet, och transformatorn är en komponent i transformatorn av-typ. Lådtransformatorer är inte transformatorer.
