GB/T 23753-2020Technical parameters and requirements for 110 kV and above oil-immersed shunt reactors (English PDF)

1 Scope

This standard specifies the terms and definitions of oil-immersed shunt reactors (hereinafter referred to as reactors) with a nominal voltage of 110kV and above.

Definition, use conditions, performance parameters, technical requirements, design and structure, inspection rules and methods, marking, lifting, packaging, transportation and storage. Unify

The performance parameters, technical requirements, design and structure of neutral point grounding reactors for 110kV and above oil-immersed shunt reactors have been determined.

Inspection rules and methods, marking, lifting, packaging, transportation and storage.

This standard applies to single-phase and three-phase oil-immersed shunt reactors with a rated frequency of 50 Hz and a system nominal voltage of 110 kV and above

The neutral grounding reactor is matched with 110kV and above oil-immersed shunt reactor.

For reactors with special requirements, such as capacitor-adjusting reactors, if the rated impedance has a ±5% or ±10% tap, it is opened through a non-excitation tap

To realize the adjustment of reactor capacity, its technical requirements can be used as reference.
