- tap changing device 抽头转换开关
- Now RCM and CCM of channel 1 HI have no voltage across them. 现在,通道1的HI线路上的RCM和CCM上没有电压。
- Operation shows that this design has high practical value which can effectually reduce the adjust times of on-load tap changing and capacitor , thus improve the voltage quantity of supply power system. 运行结果表明,这种控制思想是可行的,可以有效减少有载调压变压器分接头和电容器动作次数,从而提高供电系统的电压质量。
- The transition from voltage to no voltage is referred to as the trailing edge of a clock signal. 电感从一定值下降到0值的跃迁叫做时钟信号的后沿。
- on-load tap changing / AC voltage regulator 有载调压/交流电压调节器
- Excess current of transformer tap changing winding is limited by controlling the switching of mutual repulsive thyristors at the instantaneous of current passing zero. 采用电流在过零点的瞬间来控制互斥晶闸管组的通断以实现有载调压过程限制调压绕组过电流。

- Also, lower voltage taps are usually provided for idling and slow heatups. 通常在机器空转或者缓慢加热时用到低电压插孔。
- Nanovoltmeters and nanovolt preamplifiers will rarely indicate zero when no voltage is applied to the input, since there are unavoidable voltage offsets present in the input of the instrument. 当输入端没有施加电压时,纳伏表和纳伏前置放大器很少会指示零读数。这是因为在仪器的输入端不可避免地存在着电压偏置。
- Added two cams changing device,can easily switch between one step two points and three steps four points only pulling the changing spanner.At the same time,with automatic compensatory mechanism, can make the cams long life. 采用双凸轮切换装置,只须扳动切换扳手就可以实现,在一台机器上进行二点和四点两种线迹的切换,使凸轮的使用寿命延长,更加经久耐用。
- on load tap changing transformer 带负载抽头变换式变压器
- Ideally, when a voltmeter is connected to a relatively low impedance circuit in which no voltages are present, it should read zero. 在理想的情况下,当把电压表连接到一个没有电压的、阻抗比较低的电路时,电压表的读数应当为零。
