In view of how to strengthen the receiving-signal intensity of field of TV relay stations and increase the ability to resist jamming so as to garrantee the TV relay ing quality , this article combining with the actual conditions introduces the way of making ,setting up and site-choosing of 8 -unit biserial antenna array.

本文从如何提高电视转播台接收信号场强、增强抗干扰能力、保证电视转播质量这个角度出发，结合实际介绍了8单元双列天线阵的制作、架设与选址方法。

Time graded schemes such as over-current or distance protection schemes are examples of those providing inherent back-up protection; the faulty section is normally isolated discriminatively by the time grading, but if the appropriate relay fails or the circuit breaker fails to trip, the next relay in the grading sequence will complete its operation and trip the associated circuit breaker, thereby interrupting the fault circuit one section further back.

过流保护或距离保护可作为前一种方案的例子，通常采用分时限区别来隔离故障段，如果相应的继电器拒动或断路器拒跳，按时限下一个继电器动作跳开有关的断路器，这样就断开了故障回路的下一段。采用这种方法就获得了完整的后备保护。
