环网柜电缆头电接触部位温升阈值数学模型研究及分析

open access: yesGaoya dianqi
环网柜电缆头温升是反映其运行状况的一个重要指标,通过温升阈值判断其是否存在电接触缺陷可提高产品安全运行水平。文中通过温升试验研究了环网柜电缆头电接触部位的稳定温升与负荷电流之间的关系,并在此基础上建立了温升预警阈值数学模型。通过试验验证了温升预警阈值数学模型的正确性,为环网柜电缆头温升在线监测和预警系统提供了可靠的判断依据。

金属氧化物避雷器

open access: yesDianci bileiqi, 1991
提出了中性点绝缘网路一相长时间接地时线路和变电站的过电压保护装置的建议。避雷器接在被保护相与地之间,由两部分串连而成。接地的一部分阀片在正常时通过一个专用继电器触头短接。在一相接地时,健全相电压升高31/2倍,继电器触头跳开 ...
