Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces GB/T 21663-2008 "Small-capacity energy-saving and environmentally-friendly hidden-pole synchronous generator technical requirements", and GB/T 21663-
Compared to.2008, the main technical changes are as follows.
--- Revised the efficiency rating of some generators (see Chapter 4, Chapter 4 of the.2008 edition);
--- Increased corona test requirements (see Chapter 5);
--- Increased rotor overcurrent requirements (see Chapter 5);
--- Increased grid-connected, asynchronous operation requirements (see Chapter 5);
--- Increased maintenance measures during long-term downtime (see Chapter 5);
--- Increased the basic requirements information required by the purchaser, prime mover and generator supplier when ordering (see Appendix E).
This standard was proposed by the China Electrical Equipment Industry Association.
This standard is under the jurisdiction of the National Large Generator Standardization Technical Committee (SAC/TC511).
