应用于500 kV故障限流器的罐式快速开关研制

Gaoya dianqi
随着500 kV主网不断扩容，局部区域出现短路容量超标问题，在线路中串入由快速开关和限流电抗器并联组成的故障限流器是解决短路容量超标的有效手段，有必要研制一种应用于500 kV故障限流器的快速开关。快速开关采用罐式、多断口串联结构，依托电磁斥力机构实现断口快速分合闸；开展了斥力机构、屏蔽结构、均压、温升的仿真设计；通过单断口机械寿命、对地绝缘、端间绝缘、温升等试验，对设计进行了验证。结果表明：斥力机构方面，真空灭弧室触头分闸时间小于1 ms，最大分闸速度为7.6 m/s，连接杆上最大受力为120 kN ...

252 kV罐式断路器瓷套管断裂机理分析

Dianci bileiqi
为了明确瓷套管水泥胶装层进水冻胀导致断裂的机理，本研究以某252 kV罐式断路器瓷套管在冬季温度降低时发生断裂故障为例，建立了温差、含水率与瓷套管所受应力的数学模型，利用有限元方法计算了水泥胶装层进水冻胀时对瓷套管产生的挤压应力。最后，用试验的方法验证了计算模型的有效性。研究表明：造成瓷套管断裂的根本原因为水泥胶装层中的水分在低温下结冰膨胀对其产生挤压应力，当挤压应力超过套管的许用应力时发生断裂；运行时，水泥胶装层的含水率应控制在2.77%以内；水泥胶装层的含水率与体积膨胀率呈双曲函数关系。
