"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.
Kast-tüüpi trafo koondab trafo ja selle kõrguse, madalpinge sisend- ja väljundliiniseadmed ühte kasti ega arvesta investeeringuid hoonetesse, näiteks elektrijaotusruumidesse. Kast-tüüpi alajaam integreerib ühte kasti primaar- ja sekundaarseadmed, nagu kaitselülitid, siinid, sekundaarseadmed (kaitse, arvestid jne), alalisvoolusüsteemid jne. Üks on vähendada põrandapinda ja säästa maaressursse ning teine on säästa investeeringuid hoonetesse, näiteks elektrijaotusruumidesse. Üldiselt ei ole trafod koondunud kast-tüüpi alajaamadesse. Seetõttu on kast-tüüpi trafo kõrgepinge-lülitusseade ja trafo on kast-tüüpi trafo komponent. Kasttrafod ei ole trafod.
