黔东南干式变压器：电流互感器安装和运行的注意事项

电流互感器安装和运行的注意事项 　　
1)外壳(铁心)和二次侧必须同时接地。
2)二次侧不允许装刀黔东南干式变压器和熔断器。
3)二次回路的连接导线应用铜心绝缘线，不得使用铝心线，截面积不小于1.5mm平方。
4)二次回路的负载(Ω)，不得大于对应精确级的额定值。
5)运行中的电流互感器，二次侧不得开路，否则二次绕组产生高压，危及人身安全，并引起铁心过热。烧坏电流互感器。在运行中，如在电流互感器的二次回路上装拆仪表时，必须先将电流互感器二次侧用短路条或铜线短路。

Current transformer installation and operation precautions

1) shell (core) and secondary side must also be grounded.
2) the secondary side does not allow loaded knife switch and fuse.
3) the secondary circuit wiring applications copper heart insulated lines, may n邮 箱：1262980066@qq.comot use the aluminum center line, the cross-sectional area not less than 1.5mm square.
4) the secondary circuit load (Ω), shall not be greater than the corresponding precision level rating.
5) the operation of the current transformer secondary side shall open, or the secondary winding to generate high pressure, threat to personal safety, and caused the core overheating. Burn current transformer. In operation, such as in the current transformer secondary circuit assembly and disassembly instrument, you must first current transformer secondary short-circuit short-circuit bar or copper.
