Dianci bileiqi, 1993 据日本电气学会1992年大会论文报道,交流用避雷器阀片用于直流时未必能胜任,其寿命特性较差.因此日本开发了AC110kV/DC125kV换流站用保护晶闸管阀的直流氧化锌避雷器.介绍了该避雷器的荷电寿命特性,即使在荷电率108%和环境温度40 ...

Dianci bileiqi, 2010 从冲击老化机理,冲击老化与冲击电流峰值、波形、作用次数以及环境温度因素的相关性等方面,阐述了ZnO电阻片中流过冲击大电流的次数与寿命的关系。通过试验观察ZnO电阻片在冲击作用下的老化情况,测量ZnO电阻片变化率、功率损耗等参数来反应老化程度,分析了不同冲击电流峰值、不同波形及不同温度下的冲击次数对避雷器寿命的影响。并以此总结出一种反映避雷器大电流通过次数与寿命关系的规律,给出了以超过避雷器标称放电电流一定值的大电流通过避雷器的次数,作为避雷器寿命终结的判据。

TiO2NTs/Sb-SnO2-Ni电极制备与电化学处理废水性能
Gongye shui chuli, 2018 采用阳极氧化法制备二氧化钛纳米管（TiO2NTs）电极基底，使用热分解方法制备了Ti/Sb-SnO2-Ni和TiO2NTs/Sb-SnO2-Ni两种电极。通过扫描电镜（SEM）、X射线衍射仪（XRD）、电化学工作站等分析仪器分别研究了基底对电极表面结构、组分和电化学性能的影响。采用阳极快速寿命测试法对电极进行寿命测试，并以亚甲基蓝为模拟污染物研究了电极的电催化性能。研究结果表明，TiO2NTs为基底可有效改善电极表面结构，从而提高电极的寿命和催化性能。相比平板钛基底 ...
