6) dynamical thermal stability test
动热稳定试验
1.
When donig the dynamical thermal stability test of GW4-126 series grounding switch, the type of clap-close grounding switch is hard to pass the test, but using the rise and fall structure switch can pass successfully the test, the main reason is caused by the direction of the electrokinetic force, so solves the problem by changing the current flow direction of contact finger.
GW4-126系列接地刀闸在做型式试验中的动热稳定试验时,拍合式接地开关一般很难通过,采用升降式结构则能较顺利通过试验。
补充资料：大气暴晒试验、自然老化试验
