, 1985 将异步电机的定子剖开后平直展开,就得到一直线型的电磁感应器。其三相绕组通以三相电流,产生一个沿着感应器运动的行波磁场,这是我们通常称之为直线电机的感应器。一般谈及的直线电机,不管此感应器是作为固定边还是运动边,另一边总是固体的金属导电板或线圈。我们这里讨论的直线式电磁感应器的作用对象是液态金属,如输送液态金属的电磁流槽、直线型平面电磁泵,线型电磁搅拌器等。它的特点是由于液态金属总有管道或者流槽,且一般温度较高,须有隔热层(保温层),致使其气隙相当大 ...

Dianci bileiqi, 2018 雷电感应过电压是架空线路安全运行面临的主要威胁之一,需要对比分析采用避雷线和避雷器对线路感应过电压的防护效果。利用EMTP软件建立线路模型,编程计算雷电感应过电压,分析安装避雷线或避雷器对感应过电压的防护效果,讨论雷击点距线路距离、避雷线高度、避雷器安装间距、接地电阻等因素对感应过电压抑制效果的影响。分析结果表明:线路安装避雷线或避雷器后,感应过电压得到了不同程度的抑制,避雷器抑制过电压效果更为明显;雷击点距线路越远,避雷线的抑制效果有所增强,避雷器抑制效果减弱越明显;避雷线高度越高 ...

Dianci bileiqi, 2022 雷击是引发配电网故障的主要原因之一，可靠有效辨识雷击故障性质对配电线路防雷设计评估和采取针对性防雷措施有重要意义。本研究提出雷击配电线路电流能量溯源的原理，利用Prony算法对检测到的线路电流信号进行模式分解，分离出静电感应能量成分和电磁感应能量成分，根据不同雷击性质时能量成分占比不同的特征，对直击雷故障与感应雷故障进行辨识。通过MATLAB与ATP-EMTP联机的仿真测试，结果表明该方法能可靠有效的判别雷击故障性质。

Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT Ti‐15Mo‐2.5Ag alloy exhibited a low modulus and strong antibacterial ability but poor bioactivity. To resolve this problem, sandblasting and anodization were used to create a hydrophilic and nano‐Ag2O‐containing TiO2 coating. Subsequently, the microstructure and physicochemical properties were investigated by scanning electron microscopy, X ...
