42、 2015 IEEE. All rights reserved. viiIntroduction This introduction is not part of IEEE Std C37.14-2015, IEEE Standard for DC (3200 V and below) Power Circuit Breakers Used in Enclosures. IEEE Std C37.14-1979 superseded IEEE Std C37.14-1969, and included recognition of the widespread use of solid-sta

43、te rectifiers in industry, particularly for the traction power systems that evolved in the 1970s. It was based on known applications as well as considerations for future system development, with basic ratings and tests evolving from the classic mathematical solutions available at the time. The revis

44、ion working group for IEEE Std C37.14-1992 concluded that certain major changes were necessary. One of the changes made was the replacement of the 1200 V maximum design rating, with a new 1000 V rating. Dielectric withstand test voltages were correspondingly increased. The revision working group mai

45、ntained the peak-current multiplier of 1.65 times the sustained current, even though it can be shown that a multiplier of 1.42 can be utilized for 12-pulse rectifier designs. However, since the 6-pulse rectifier designs can produce the 1.65 peak, and because of unknown future applications with addit

46、ional and/or replacement circuit breakers, it was preferred to maintain the 1.65 value. Rated peak current was maintained as a rating because depending on the transformer/rectifier-design impedance coupled with the primary short-circuit current capacity and a lower dc inductance, it may be possible

47、to obtain a higher peak current and/or sustained current, depending on conditions. This design combination should be investigated to prevent inadvertent application of circuit breakers above their ratings. Some considerations that were addressed in the IEEE Std C37.14-1992 revision are as follows: a

48、) The need for lower rated circuit breakers for light-duty transit systems, which are generally 800 V catenary surface systems, was recognized. The power requirements are approximately one-half those of a heavy-duty transit system, with the rectifier circuit breakers requiring maximum continuous cur

49、rent ratings of 4000 A and feeder circuit breakers with proportionately lower ratings. Tables 12 and 12A were replaced with a new Table 12 in ANSI C37.16a, which was revised to reflect a reduced base rating of 4000 kW in order to provide a lower level of design rated circuit breakers, which allows the use of designs differing from those utilized for heavy-duty systems. b) The question of rectifier and feeder circuit breakers being rated identically was previously addressed in the IEEE C37.14-1979 appendix, but this was now recognized and addressed in the body of the standar
