摘要
10 kV配电变压器一次保护配置主要有高压断路器、高压熔断器和高压负荷开关—熔断器组合电器等。高压断路器技术性能好,但设备投资较高,使用复杂;高压熔断器可断开短路电流,具有经济方便的功效;高压负荷开关—熔断器组合电器可切断短路电流,操作简单方便。
Primary protectors of 10kV distribution transformers include high-voltage breaker,high-voltage fuse plug,the combi-nation high-voltage switch-disconnector and fuse.The high-voltage breaker is good in technological performance,but expensive and com-plex.The high-voltage fuse plug may disconnect the short-circuit current and is economic.The combination of high-voltage switch-discon-nector and fuse may cut off the short-circuit current and is easy to operate.
