---Expanded the scope of application of the standard (see Chapter 1, Chapter 1 of the.2009 edition);
---Modified the normative references (see Chapter 2, Chapter 2 of the.2009 edition);
---Added the conditions of use (see Chapter 4);
---Modified the technical content of 330kV and 500kV (see Chapter 7 and Chapter 8, Chapter 4 ~ Chapter 8 of the.2009 edition
chapter);
---The technical parameters and requirements of 110kV, 220kV, 750kV and 1000kV oil-immersed shunt reactors have been added (see Chapter 5,
Chapter 6, Chapter 9, and Chapter 10);
--- The content of the appendix has been modified and supplemented (see Appendix A, Appendix A of the.2009 edition).
This standard was proposed by China Electrical Equipment Industry Association.

---GB/T 23753-2009.
110kV and above oil-immersed shunt reactor
Technical parameters and requirements
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.
