GB/T 23753-2020 (English Version) PDF

Scope: This standard specifies the terms, definitions, conditions of use, performance parameters, technical requirements, design and structure, inspection rules and methods, symbols, Lifting `packaging. Transport and storage. It also stipulates the performance parameters, technical requirements, design and structure, inspection rules and methods, marking, lifting, packaging, transportation and storage of the neutral point grounding reactor used for supporting oil-immersed shunt reactors of 110 kV and above. This standard applies to single-phase and three-phase oil-immersed shunt reactors with a rated frequency of 50 Hz and a nominal voltage of 110 kV and above, and neutral point grounding reactors for 110 kV and above oil-immersed shunt reactors . For reactors with special requirements, such as capacity-adjusting reactors, if the rated impedance has ±5%% or ±10%% taps, the adjustment of reactor capacity can be realized through off-excitation tap changers, and its technical requirements can be referred to. .
