"Box change" is the abbreviation of box-type substation, also known as pre-installed substation or pre-installed substation. It is a high-voltage switchgear, distribution transformer and low-voltage power distribution device. It is a prefabricated indoor and outdoor compact power distribution equipment that is integrated into a single wiring scheme. It combines the functions of transformer step-down and low-voltage power distribution organically. Together, it is installed in a steel structure box that is moisture-proof, rust-proof, dust-proof, rodent-proof, fire-proof, anti-theft, heat-insulated, fully enclosed and movable. It is especially suitable for urban network construction and renovation. It is a rise after the civil construction substation. A new 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 substation and becomes a new type of transformer distribution equipment.
Box-changing "combined" equipment containing high-voltage inlet and outlet lines, metering devices, transformers, low-voltage incoming lines, low-voltage distribution lines, etc., is equivalent to a complete substation. However, box-type substations are usually installed outside the building, so there is no special requirement for the selection of transformers, and oil-immersed transformers are generally used.
So what is the transformer? The following small series briefly introduces one of the transformers.
Dry-type transformer: It is only a kind of transformer. Because the heat dissipation of dry-type transformer winding is natural heat dissipation or forced air cooling (forced air convection by fan), it has no flammable and explosive substances, so it is widely used in places with high requirements. , such as the basement inside the building. Different from the oil-immersed transformer, the convection of the transformer oil is used to dissipate heat, and the transformer oil may be burned under the accident condition or may not be directly installed in the above place.
Summary: Box change is a box-type substation is a high-voltage switchgear, the transformer is a component of the box change. So the box is not a transformer.
