市电频率 meaning in Chinese
commercial electricity frequency
commercial frequency
commercial power frequency
mains frequency
Examples
- This is fairly commonly utilized , and affects the line frequency component ( and odd harmonics )
这种作法已经被广泛应用，并可以用以改善市电频率成分（包括奇次谐波。 ） - The cathode bypass should be " effective " well below the " mains " frequency " , which is usually the case anyway
阴极旁路电容的截至频率应该远低于市电频率，这点应该在任何情况下都需要注意的。 - Physically , the filament minutely heats up and cools down at twice the line rate , due to ac applied to the filament
实际上，由于加载在灯丝上的交流电，灯丝基本上是以两倍市电频率加热或冷却。 - The hardware of the control system mainly consists of the dsp controller , the sampling and pre - processing units of analog signals such as output voltage , output current , input voltage , etc , and the insulation and driving units of pwm signals
系统硬件部分主要包括输出电压、输出电流、市电频率相位等各类信号的采集和处理，以及输出pwm信号的隔离、驱动等。 - At power frequencies ( 45 hz to 60 hz ) , the measuring range can be extended to 100 a . however , the calibrator under test must be capable of driving inductive loads as precision current transformers will be used for the measurements in this extended range
有关的测量量程在市电频率( 45hz至60hz )可扩大至100a 。但由于在此扩大量程的测量需使用精密电流变压器，故此接受测试的校正器必须有驱动电感负载的能力。
