4、stract: This standard covers the rating structure for all high-voltage circuit breakers, whichinclude all voltage ratings above 1000 V ac and comprise both indoor and outdoor types having thepreferred ratings as listed in ANSI C37.06-1997. Typical circuit breakers covered by thesestandards have maxi
5、mum voltage ratings ranging from 4.76 kV through 800 kV, and continuouscurrent ratings of 600 A, 1200 A, 2000 A, and 3000 A associated with the various maximum voltageratings. The rating structure establishes the basis for all assigned ratings, including continuouscurrent, dielectric withstand volta

20、roduction is not part of IEEE Std C37.04-1999, IEEE Standard Rating Structure for AC High-Voltage CircuitBreakers.)In 1964, consolidated standards for circuit breakers rated on a symmetrical current basis were published totake the place of standards established on the total current basis of rating.
21、This 1999 revision was undertakento update the standard to reflect todays circuit breaker technology and application on modern power sys-tems. The revision also continues harmonization with IEC 60056 Ed. 4.0b: 1987, a process that first began in1951.This document makes significant changes in the rat
22、ing structure for circuit breakers, such as the change ofthe voltage range factor, K, and the standard duty cycle. With these changes, information needed to properlyapply circuit breakers rated in accordance with the 1979 or 1964 editions of IEEE Std C37.04 are eliminatedfrom this new edition. Accor
23、dingly, users must refer to the prior editions of the relevant standards (includingIEEE Std C37.04-1999, ANSI C37.06, IEEE Std C37.09-1999, etc.) in order to properly select and apply cir-cuit breakers rated in accordance with the older standards.NOTEThese older standards are part of the IEEE archiv
24、es. Contact the IEEE Standards Association for orderinginformation.The changes in this standard are explained in the following clause-by-clause summary: 1. ScopeThe scope was expanded to clarify the type of circuit breakers specifically covered by thisstandard.2. ReferencesA complete updated listing
25、 of references is supplied.3. DefinitionsNo substantial changes.4. Service conditionsThe usual and unusual service conditions are given. Information given on howto deal with unusual service conditions has been moved to IEEE Std C37.010-1999.5. RatingsThe rated voltage range factor, K, defined in ear
26、lier versions of IEEE Std C37.04is com-monly recognized as being equal to 1.0 for modern interrupting technologies; consequently, the rat-ing structure has been simplified, because the use of a K factor of 1.0 has effectively eliminated Kfrom the rating structure. The rated permissible tripping dela
27、y, Y, has been incorporated in the ratedclosing, latching, and short-time current carrying capability (5.8.2.3).5.1 Rated maximum voltageNo major changes.5.2 Rated power frequencyNo major changes.5.3 Rated continuous currentChanges were made to Table 1 (Limits of temperature and temper-ature rise fo

32、nt carrying capability (5.8.2.3) incorpo-rates the permissible tripping delay and short-time current into values that coordinatewith IEC. The required reclosing capability is referenced to IEEE Std C37.010-1999.5.9 Rated transient recovery voltage (TRV)This subclause of the standard was expanded top
33、rovide a detailed explanation of how TRV values are calculated. The first pole-to-clear factorand transient amplitude factors have been harmonized with IEC in preparation for future har-monization of waveshapes for testing. The shortline fault surge impedance and amplitudeconstant were harmonized to
34、 a single value. The initial TRV was incorporated from IEEE StdC37.04i-1991.5.10 Rated operating endurance capabilitiesThis subclause replaced “Required load currentswitching capability and life.”5.11 Rated capacitance current switchingThis subclause was not changed. Requirements forcapacitance swit
