An adjustable high voltage supply to operate the counter is necessary . 必须备有一台供给计数器用的可调高压电源
Calibration of a single range dc high voltage supply 校正一单量程直流高压电源。
The high voltage supply to the test electrode shall beeither alternating current , direct current , high frequency current or impulsedcurrent as specified in 4 . 1 通常采用的测试高压电源有交流、直流、高频和脉冲。在4 . 1中有详细介绍。
Discuss the method to improve the efficiency of collecting signal and signal - noise ration . make the setup of detection device , high voltage supply of pmt and low - noise preamplifier ; doing lif detection experiment to green fluorescent dye 详细讨论了提高荧光采集效率和信噪比的措施,制作了探测机构、光电倍增管的高压供电电路和前置放大器。
Dc high voltage supplies rated up to 30 kv can be calibrated . the basic calibration will include measurement of output high voltages at appropriate settings or values indicated by an output voltmeter ( normally not exceeding 5 voltage values ) 本所可校正30kv或以下的直流高压电源,基本校正工作包括测量该电源在其输出定位或显示数值下的高压电量。
Owners of premises having high voltage fixed installations that are fed directly from a high voltage supply are required to have their high voltage fixed electrical installations inspected , tested and certified at least once every year 房产如设有由高压电源直接供电的高压固定电力装置,则该房产的拥有人须安排该高压固定电力装置每年最少作一次检查、测试及领取证明书。
Since for ages , most of the mine high voltage support system are adopted 6kv power over energy , but recent years , with the development of highly output , highly efficient technologies , with the widely adopted of a large number of heavy excavated equipments and high power lifting services , especially the dramatically increase in load under the well and the usage of 10 kv high pressure motors , 10kv high voltage supply has gradually become dominant power supply for coal mining power supply system 长期以来,我国煤矿高压供电多采用6kv供电系统。但近年来随着煤矿高产高效技术的发展,大量重型采掘设备和大功率提升设备被广泛采用,特别是井下负荷急剧增加,以及10kv高压电机的投入使用,使得10kv供电开始逐渐开始进入煤矿高压供电系统。
