摘要: 10KV电缆的超低频耐压试验方法 1、将与试品相连的电器设备全部脱离试品电缆。 2、采用10000V兆欧表对试品电缆各相分别进行绝缘电阻试验,记录试验值。 3、试验电压峰值:Umax=3Uo,其中Uo为电缆导体对地或金属屏蔽之间的额定工作电压。例如:额定电压为10KV电缆,单相额定电压 Uo: Uo=10/√3kV 所以试验电压峰值为:Umax=3Uo =3×10/√3kV =√3×10kV =17.32kV 4、试验时间:3分钟。 5、可分相进行测试。试品电缆的电容值在试验...

o=10/√3kV

所以试验电压峰值为:Umax=3Uo

=3×10/√3kV

√3×10kV

=17.32kV
