DC reactors, as key components in power electronics systems, are primarily used to suppress harmonics, stabilize current, and improve system reliability. Their performance and safety are directly related to the operational efficiency of the entire power system, and therefore must strictly adhere to relevant implementation standards.
Internationally, the manufacture and testing of DC reactors generally refer to IEC (International Electrotechnical Commission) standards, such as IEC 60076-6 (Power Transformers - Part 6: Reactors) and IEC 61000 (Electromagnetic Compatibility Series of Standards). These standards specify reactor electrical parameters, insulation performance, temperature rise limits, and electromagnetic interference (EMI) control requirements. In addition, IEEE (Institute of Electrical and Electronics Engineers) standards such as IEEE C57.12.00 also provide guidance on reactor design, testing, and operation.
In China, the standards for DC reactors are primarily based on GB/T 10229-2015 (General Technical Requirements for Reactors) and GB/T 17468-2019 (Sound Level Measurement for Power Transformers and Reactors). These national standards set clear requirements for reactor rated voltage, current, temperature rise, insulation level, and mechanical strength, and prescribe strict testing methods, including no-load tests, load tests, and short-circuit withstand tests. DC reactors must also comply with GB/T 14549-1993 (Power Quality - Public Grid Harmonics) to ensure their ability to suppress grid harmonics.
In industrial applications, different scenarios (such as renewable energy generation, rail transit, and industrial frequency conversion) may have additional requirements for DC reactors. Therefore, companies should also refer to specific industry standards, such as NB/T 42022-2013 (Technical Specifications for DC Reactors for Photovoltaic Power Generation).
In summary, the implementation standards of DC reactors cover multiple levels at the international, national and industry levels, ensuring that they reach the optimal level in terms of safety, reliability and electromagnetic compatibility, thereby ensuring the efficient and stable operation of the power system.
