The Role Of Oil-Immersed Transformers In Box Type Substation
"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.
The box-type transformer only concentrates the transformer and its height, low-voltage input and output line equipment in one box, and does not consider the investment in buildings such as power distribution rooms. The box-type substation integrates primary and secondary equipment such as circuit breakers, busbars, secondary equipment (protection, meters, etc.), DC systems, etc. into one box. One is to reduce the floor space and save land resources, and the other is to save investment in buildings such as power distribution rooms. Generally speaking, transformers are not concentrated in box-type substations. Therefore, the box-type transformer is a high-voltage switching device, and the transformer is a component of the box-type transformer. Box transformers are not transformers.
