摘要

文中从c-C

的绝缘性能和绝缘子沿面闪络特性角度出发

进行了球板电极下对c-C

的工频击穿实验和雷电冲击实验

以及常压下绝缘子的沿面闪络击穿实验。同时进行了SF

、N

和CO

的对比实验。实验结果表明

对于气隙击穿的工频耐压实验和雷电冲击实验

c-C

的击穿电压值都随着间隙距离的升高而增加

并呈线性趋势;在稍不均匀电场中

c-C

的绝缘性能约为SF

的1.4倍;c-C

中绝缘子的闪络电压明显大于SF

。从绝缘性能的角度来看

c-C

在某些条件下可以作为SF

的一种替代气体

用在电力设备中。

Abstract

From the perspective of c-C

insulation performance and insulator flashover characteristics

the breakdown voltage of c-C

in sphere-plate electrode gap under different pressures and with different gap lengths have been measured. The power frequency breakdown voltage

lightning impulse withstand voltage and surface flashover voltage are compared with SF

and CO. Results show that the breakdown voltage increases with the gap length linearly. In slightly nonuniform field

the breakdown voltage of c-C

is about 1.4 times that of SF

;the flashover voltage of c-C

around an insulator is significantly greater than that of SF

. Therefore

from an insulation point of view

c-C

can be used as an alternative to SF

under certain conditions.
