Introduction This introduction is not part of IEEE Std C57.12.10-2010, IEEE Standard Requirements for Liquid-Immersed Power Transformers. This standard was prepared by the Revision of C57.12.10 Working Group

3、 of the Power Transformers Subcommittee of the Transformers Committee of the IEEE Power and Energy Society. The purpose of this standard is to cover the dimensional, electrical, and mechanical characteristics for liquid-immersed power transformers and autotransformers. This standard is a revision of

4、 ANSI C57.12.10-1997, American National Standard for Transformers230 kV and Below 833/958 through 8333/10 417 kVA, Single-Phase, and 750/862 through 60 000/80 000/100 000 kVA, Three-Phase Without Load Tap Changing; and 3750/4687 through 60 000/80 000/100 000 kVA with Load Tap ChangingSafety Requirem

5、ents. The focus of this revision was to expand the scope of the standard and to include the requirements for power transformers and autotransformers with high voltage up to 765 kV and with no limit on the megavoltampere rating. This revised standard includes the following significant changes: The ti

6、tle was changed. The scope was expanded to include autotransformers, increase the upper voltage limit to 765 kV, and remove the maximum megavoltampere limit. Distribution substation transformers, as defined in IEEE Std C57.12.36B1,awere excluded from this standard. Most of the clauses were revised,

7、rewritten, or rearranged. Significant changes were made in the load tap changer (LTC) section. Additional requirements for transformer paralleling operation were added. An informative annex on LTC considerations was added. This standard is a voluntary consensus standard. Its use may become mandatory

Overview 1.1 Scope This voluntary consensus standard sets forth the requirements for power transformer application. This standard is intended to be used as

42、 a basis for performance, interchangeability, and safety of the equipment covered and to assist in the proper selection of such equipment. This document is a product standard that covers certain electrical, dimensional, and mechanical characteristics of 50 Hz and 60 Hz, liquid-immersed power transfo

43、rmers and autotransformers. Such power transformers may be remotely or integrally associated with either primary switchgear or substations, or both, for step-down or step-up purposes and base rated as follows: 833 kVA and above single-phase, 750 kVA and above three-phase. This standard applies to al

44、l liquid-immersed power transformers and autotransformers that do not belong to the following types of apparatus: a) Instrument transformers b) Step voltage and induction voltage regulators c) Arc-furnace transformers d) Rectifier transformers e) Specialty transformers IEEE Std C57.12.10-2010 IEEE S
