光纤布拉格光栅电气测温系统的研究和设计

open access: yesGuangtongxin yanjiu, 2013
为了避免电力系统中设备或者线缆发热引起火灾事故,实现对电气设备的在线温度监测已成为电力系统安全与稳定的重要保障。文章设计并实现了一种高速率、高精度和低成本的适合工程应用的分布式光纤光栅电气测温系统,对陶瓷封装的光纤光栅传感器的温度响应特性进行了实验验证,结果表明,光纤光栅传感器的反射波长与温度具有良好的线性关系。通过对电力高压开关柜的长期温度监测,证明了该系统具有良好的稳定性和较高的测温精度,适用于电力系统测温领域。

城市配电网中性点接地方式适应性评价研究

open access: yesDianci bileiqi
随着城市的不断发展,城市配电网负荷快速增长和电缆线路的普及,电容电流逐渐增大,城市配电网现有中性点接地方法存在安全问题。为加强10 kV配电网电容电流治理,适应不同城市配电网发展,防止接地电弧引发火灾、电缆起火等故障发生,本研究提出一种10 kV配电网中性点接地方式适应性评价策略。首先,通过分析配电网中性点接地方式中不同影响因素,构建不同情况下影响因素的权重系数模型,并对不同的影响因素进行权重分配。然后,根据不同主要因素的权重分配结果确定初步方案,在此基础上根据次要因素进行校核并确定最终中性点接线方式 ...
