摘要

在电力系统的配电电路中，使用负载断开开关和分段器来执行开关操作是很常见的。隔离输电网局部区域的功能需求正在扩大，因此需要一种新型的具有成本效益和可靠的开关设备。本文讨论了利用传输类交换设备性能的一些应用。SF/sub 6/断流器通过在72.5 kV至242 kV电压范围内使用单个断流断流器，解决了传输级开关可靠性问题。新的设计配置提高了具有成本效益的传输级交换器件的额定电流。文中还对几种应用进行了说明和成本比较。

New improvements in transmission switching using SF/sub 6/ interrupter technology

The use of load break switches and sectionalizers to perform switching operations is common in the distribution circuits of electrical power systems. The functional need to isolate local regions of the transmission grid is expanding and, as a result, a new class of cost effective and reliable switching devices is needed. This paper discusses some applications where the capabilities of a transmission class switching device are employed. The SF/sub 6/ interrupter solves transmission class switching reliability concerns by utilizing a single break interrupter for voltages of 72.5 kV through 242 kV. The new design configuration increases the ampacity ratings available in cost effective transmission class switching devices. Several application descriptions and cost comparisons are included in the paper.
