摘要
雷电冲击耐压试验是检验GIS(Gas Instulated Switchgear,气体绝缘全封闭配电装置)设备绝缘性能的重要手段。特高压大容量GIS设备的雷电冲击试验经常遇到波头时间Tf和过冲系数?超标问题。本文依托厦门理工学院高压电力大厅的试验场地和3000kV/300kJ冲击电压发生器,以1100kV GIS设备(电容量为2500pF)为研究对象,试验中通过优化波头电阻排列、改善高压导线布置、串接阻容装置等方法,使试验波形中的波头时间Tf从最初的1.84?s降低到1.56?s,同时保证过冲系数β不超过10%。本文对特高压大容量设备雷电冲击试验具有一定借鉴意义。
Lightning impulse endurance test is an important means to check the insulation performance of GIS equipment. The lightning impulse test of UHV and large capacity GIS equipment often encounter the problem of wave head time Tf and overshoot coefficient ?. Based on Xiamen University of Technology high voltage power hall test site and the 3000kV/300 kJ impulse voltage generator, taking the 1100 kV GIS equipment(capacity 2500pF) as the research object, the test was carried out to reduce the wave front Tf from the original 1.84μs to 1.56μs by optimizing the arrangement of wave head resistance, improving the high voltage wire layout and concatenating resistance capacity device, and guarantee the overshoot coefficient β is maintained within 10% at the same time. This paper offers a reference for UHV large capacity equipment lightning impulse test.
