Description
The product represented by this dataset is a dry-type reactor, namely an oil-free power device using a coil containing a dielectric as the impedance element, with a single-unit weight of about 836.18 kg, mainly composed of electrical steel, channel steel, magnet wire and epoxy resin, etc., manufactured through processes such as iron core production, coil production, assembly and testing. The key upstream raw materials of this product are insulating materials such as electrical steel, channel steel, magnet wire and epoxy resin, and the downstream is mainly applied to power system stability and the power transmission and loss control of places such as converter stations, cable lines and generators. As for the system boundary, the packaging of the product and its post-delivery transport, use, scrapping, recycling and final disposal, as well as infrastructure such as the manufacture of production equipment and plant construction, are not included within the dataset boundary. In terms of data sources and data processing, the data inventory is formed by merging data from multiple sources.
Activity Description
The system boundary for the dry-type reactor is set from cradle to gate, with the starting point being the input of raw materials and the end point being the dispatch of the finished dry-type reactor from the plant. The primary stages, in sequential order, comprise core production (including electrical steel and channel steel), coil production (including magnet wire and epoxy resin), assembly, and testing.
Process Description
Reactors are electrical components in circuits that use inductance to resist changes in current. They are mainly divided into dry-type reactors and oil-immersed reactors. Reactors play an important role in the fields of power system stability, electronic equipment protection, and precise signal control by virtue of their current control capabilities. Dry-type reactor is a kind of power equipment used to improve power transmission efficiency and reduce losses in power transmission, distribution, transformation and other occasions. It uses coils containing dielectric as impedance elements. It is mainly composed of iron core (electrical steel, channel steel, etc.), coil (magnetic wire wound) and insulating materials (such as epoxy resin). The structure is oil-free to avoid shortcomings such as oil leakage and flammability. It is in the form of bench-mounted or cabinet-mounted reactors. It is widely used in power stabilization and transmission in converter stations, cable lines, generators and other places.

Technology comment
The production of dry-type reactors mainly includes core production, coil production, assembly, testing, and packaging. Channel steel and electrical steel are processed, stacked, spray-coated, and dried to form the core; magnet wire is wound into a coil, and insulation materials are vacuum-cast and dried before being assembled with the core. After testing, the finished dry-type reactor is obtained.
