摘要
对一种SF6 气体绝缘电流互感器外绝缘试验结果进行了分析 ,认为增加套管高度并不能有效地提高空气间隙的放电电压 ,提出了两种改进措施。
The test results on the outer insulation electric strength of a SF 6 gas-insulated current transformer are analyzed. It is pointed out that the increase of porcelain bushing height can not improve the discharge voltage of air clearance effectively. Two improving measures are given.
