, 2001 近年来俄罗斯的科技工作者发明了一种把水(水蒸气)同时作为冷却剂和工作介质的、切割和焊接两用的新型等离子枪,我们借鉴于他们的技术正在进行这种等离子枪的研制。这种等离子枪具有一些独特的优点:电弧热能得到充分的利用,因而效率极高;省去了笨重的高压气瓶和水/气管路,也无高压电路和高压电缆,整套设备不超过6kg ...

Dianci bileiqi, 2018 为使动车组高压设备箱满足高海拔地区运行条件,需将高压设备箱雷电冲击耐受电压设计值从铁道行业标准TB/T 1333.1-2002中的OV3（Overvoltage 3,125 kV）考核指标提高到OV4（170 kV）考核指标。考虑到高压设备箱空间结构限制,提出了在高压设备箱内电缆终端、断路器端部等关键部位加装绝缘护套的方法,针对电缆终端及断路器端部高压电极形状设计不同结构的绝缘护套,试验研究不同优化策略下冲击闪络电压耐受值。结果表明,通过加装结构合理的绝缘护套,高压设备箱雷电冲击电压耐受值可满足海拔3 ...

Guangtongxin yanjiu, 2004 随着电压等级的不断提高,超高压输电线路发展非常迅速.但是这些架空输电线路在运行时,附近存在较高的电场,对周围物体和公用走廊的其它线路会产生影响.电压等级越高,产生的电场影响越大.输电线路产生的电场越来越受到人们的重视.尤其是对于超高压输电线路,由于在电力铁塔上同塔悬挂全介质自承式光缆（ADSS）,因此分析工频电场对ADSS光缆特性的影响非常必要.
