Description
The product represented by this dataset is an electronic current transformer, namely a current transformer using electronic devices to achieve signal conversion, with a single-unit weight of about 2.4 kg, mainly composed of an iron core, coils wound from enamelled wire and insulating materials such as epoxy resin, manufactured through processes such as iron core fabrication, coil winding, insulation and assembly. The key upstream raw materials of this product are the iron core, enamelled wire and epoxy resin, etc., and the downstream is mainly applied to measurement and protection in industries such as power, industrial automation, construction and electric energy metering. As for the system boundary, infrastructure such as the manufacture of production equipment and plant construction is not included within the dataset boundary. In terms of data sources and data processing, the data inventory is taken from the actual situation of production enterprises, and energy such as electricity is calculated using China's average energy mix.
Activity Description
The system boundary for the electronic current transformer 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 electronic current transformer from the plant. The primary stages, in sequential order, comprise core fabrication (including magnetic cores), coil winding (including magnet wire), insulation (including epoxy resin), and assembly.
Process Description
A current transformer is a transformer in which the secondary current is actually proportional to the primary current under normal use conditions, and the phase difference is close to zero when the connection method is correct. According to the insulation material and operation mode, it can be divided into dry type, oil-immersed type, SF6 and electronic current transformer. Electronic current transformers refer to current transformers that use electronic devices to achieve signal conversion. They are mainly composed of cores, coils (wound by enameled wire) and insulating materials (such as epoxy resin). They are in the form of bench-mounted or cabinet-mounted transformers. They are widely used in measurement and protection in industries such as electric power, industrial automation, construction, and electric energy measurement.

Technology comment
The production of electronic current transformers mainly includes processes such as core making, coil winding, insulation and assembly. The enameled wire is wound to form a coil, and after being assembled with the iron core into an assembly, it is insulated and assembled with epoxy resin to form a finished electronic current transformer.
