第三章整流火花的测定 3-3 测量结果及分析 3-3-1 火花等级及火花持续时间请看图3-5。每片换向片上产生火花是不一样大的,图中就反映出它们的实际状况。(α)为目测4火花(见第一章)。在4级火花时,整流火花持续时间极短(平均1.12微秒),而且不同换向片又有很大差别(从0到约5微秒)这也是容易理解的。 7火花是指整个换向器表面都有火花,且火花持续时间可长达约7微秒之久。
Chapter 3 Determination of Rectifier Spark 3-3 Measurement Results and Analysis 3-3-1 Spark Ratings and Spark Duration See Figure 3-5. Each piece of commutator sparks are not the same size, the figure reflects their actual situation. (α) is the visual 4 spark (see Chapter 1). Rectifier sparks have very short durations (average 1.12 microseconds) at level 4 sparks and are very different for different commutators (from 0 to about 5 microseconds) as is easy to understand. 7 Spark means that there is a spark across the face of the commutator and the spark lasts up to about 7 microseconds.
