What is the difference between box type substation and box type transformer? Transformer is a device that transforms AC voltage, 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) to induce voltage (or current) in the secondary coil. The transformer consists of an iron core (or magnetic core) and a coil. The coil has two or more windings. The winding connected to the power supply is called the primary coil, and the other windings are called the secondary coil. In the generator, no matter whether the coil moves through the magnetic field or the magnetic field moves through the fixed coil, the potential can be induced in the coil. In both cases, the value of magnetic flux remains unchanged, but the number of magnetic flux in the chain intersecting the coil changes, which is the principle of mutual inductance. Transformer is a device that uses electromagnetic mutual inductance to transform voltage, current and impedance.
Box type substation:
It is also called prefabricated substation or prefabricated substation. It is a factory prefabricated indoor and outdoor compact power distribution equipment with high-voltage switchgear, distribution transformer and low-voltage power distribution device arranged according to a certain wiring scheme, that is, the functions of transformer step-down and low-voltage power distribution are organically combined and installed in a moisture-proof, rust proof, dust-proof, rat proof, fire-proof, anti-theft, heat insulation, fully enclosed and movable steel structure box, It is especially suitable for urban network construction and transformation. It is a new substation rising after civil substation. Box type substation is suitable for mines, factories, oil and gas fields and wind power stations. It replaces the original civil power distribution room and power distribution station and becomes a new complete set of power transformation and distribution equipment.
Box type transformer:
As a complete set of distribution equipment, box transformer is organically composed of transformer, high voltage control equipment and low voltage control equipment. Its basic principle is that through the pressure starting system, armored wire, substation automatic system, DC point and corresponding technical equipment, all components are reasonably assembled according to the specified sequence, and all components are installed in the specific waterproof, dustproof and rat proof fully sealed toughened box structure, so as to form a specific transformer. At present, box transformer has been widely used in power engineering construction.
difference:
Box type substation and box type transformer are a kind of distribution equipment, which are called differently in different places.
