1、Recognized as an American National Standard (ANSI) IEEE C57.12.26-1992 (Revision of ANSI C57.12.26-1987) IEEE Standard for Pad-Mounted, Compartmental-Type, Self-Cooled, Three-Phase Distribution Transformers for Use With Separable Insulated High- Voltage Connectors (34 500 Grd Y/19 920 V and Below; 2
2、500 kVA and Smaller) Sponsor Transformers Committee of the of the IEEE Power Engineering Society Approved June 18, 1992 IEEE Standards Board Approved June 9, 1993 American National Standards Institute Abstract: This standard is intended for use as a basis for determining performance, interchangeabil
3、ity, and safety of the equipment covered, and for assisting in the proper selection of equipment. It covers certain electrical, dimensional, and mechanical characteristics and takes into consideration certain safety features of three-phase, 60 Hz, mineral-oil-immersed, self-cooled, pad-mounted, comp
4、artmental-type distribution transformers with separable insulated high-voltage connectors. These transformers are rated at 2500 kVA and smaller, with high voltages of 34 500 Grd Y/19 920 V and below and with low voltages of 480 V and below. These transformers are used generally for step-down purpose
5、s from an underground primary cable supply. Connector and terminal arrangements for both radial-feed and loop-feed systems are included. This is an approved IEEE Standard. Previous versions of this standard were copyrighted by the American National Standards Institute. Permission has been granted to
6、 include ANSI copyrighted C57 standards in this collection. Single copies are not yet available. IEEE Standards documents are developed within the Technical Committees of the IEEE Societies and the Standards Coordinating Committees of the IEEE Standards Board. Members of the committees serve volunta
7、rily and without compensation. They are not necessarily members of the Institute. The standards developed within IEEE represent a consensus of the broad expertise on the subject within the Institute as well as those activities outside of IEEE that have expressed an interest in participating in the d
8、evelopment of the standard. Use of an IEEE Standard is wholly voluntary. The existence of an IEEE Standard does not imply that there are no other ways to produce, test, measure, purchase, market, or provide other goods and services related to the scope of the IEEE Standard. Furthermore, the viewpoin
9、t expressed at the time a standard is approved and issued is subject to change brought about through developments in the state of the art and comments received from users of the standard. Every IEEE Standard is subjected to review at least every five years for revision or reaffirmation. When a docum
10、ent is more than five years old and has not been reaffirmed, it is reasonable to conclude that its contents, although still of some value, do not wholly reflect the present state of the art. Users are cautioned to check to determine that they have the latest edition of any IEEE Standard. Comments fo
11、r revision of IEEE Standards are welcome from any interested party, regardless of membership affiliation with IEEE. Suggestions for changes in documents should be in the form of a proposed change of text, together with appropriate supporting comments. Interpretations: Occasionally questions may aris
12、e regarding the meaning of portions of standards as they relate to specific applications. When the need for interpretations is brought to the attention of IEEE, the Institute will initiate action to prepare appropriate responses. Since IEEE Standards represent a consensus of all concerned interests,
13、 it is important to ensure that any interpretation has also received the concurrence of a balance of interests. For this reason IEEE and the members of its technical committees are not able to provide an instant response to interpretation requests except in those cases where the matter has previousl
14、y received formal consideration. Comments on standards and requests for interpretations should be addressed to: Secretary, IEEE Standards Board 445 Hoes Lane P.O. Box 1331 Piscataway, NJ 08855-1331 USA IEEE Standards documents are adopted by the Institute of Electrical and Electronics Engineers with
15、out regard to whether their adoption may involve patents on articles, materials, or processes. Such adoption does not assume any liability to any patent owner, nor does it assume any obligation whatever to parties adopting the standards documents. -,-,- iii Foreword (This foreword is not a part of I

The Accredited Standards Committee on Transformers, Regulators, and Reactors, C57, has for many years b
17、een developing standards on transformers, regulators, and reactors. The data has been obtained from many sources, including the standards of the Institute of Electrical and Electronics Engineers (IEEE) and the National Electrical Manufacturers Association (NEMA), reports of committees of the Edison
18、Electrical Institute, and others. This standard was prepared by the Working Group of the Subcommittee on Distribution Transformers, Overhead and Padmounted C57.12.2, and is a revision of the 1987 edition. Significant additions to this edition are the percent impedance voltage for transformers below
19、750 kVA, a drain value requirement, and additional sections on storage and installation. The Accredited Standards Committee on Transformers, Regulators, and Reactors, C57, that reviewed and approved this document, had the following members at the time of approval: P. J.
