Experimental Study on Breaking Capacity of Splitter Arc Extinction Type Load Switch in Medium High Voltage Ring Main Unit
摘要
对某型12kV环网柜SF6负荷开关进行了电流开断实验
观察研究了开断过程中的电弧运动特性
通过高速摄影仪拍摄的图像揭示了电弧运动规律。根据实验结果的分析
对负荷开关做了相应的改进
之后又进行了实验对比验证
经实际测试证明了改进的合理性和有效性
为负荷开关的设计和优化提供了参考。
Abstract
Current breaking experiments on a certain type of medium high voltage ring main unit’s SF6 load switch were conducted.The arc movement characteristics during breaking process were observed
and the movement law was revealed by the images recorded by a high-speed digital camera.According to the analysis of the experimental results
the load switch was improved correspondingly and validated by test.This study may provide a reference for design and optimization of load switches.
