避雷器

LIGHTNING ARRESTER

    闪电雷击对无线电设备意味着一场考验。在几微秒的瞬间，浪涌电压高达几十千伏/ 米，整个系统将承受巨大的负载，后果可能损坏设备。避雷器是在建设机站时采用的**保护性、预防性的附件。正确的选用可确保系统**运作。

    Lightning strike by lightning means a calamity to the radio equipment. At the severalty microseconds twinkling of an eye, well up to the dozens ofth kilovolt of at voltage at waves /rice, bear enormous load of whole systems, May damage the equipment in consequence. It is with lightning arrester must protecting nature, preventative enclosure fully. Correct exertion, guarantee system high-efficient operation.

气体管式避雷器GAS TUBE DISCHARGE TYPES

利用特殊的气体管放电原理来压制过高电压。

Utilizing special gas to be in charge of discharging, the principle suppress the too high voltage.

当浪涌电压大于气体管的规定时，气体管会将过高的电压放电接地，保护系统器材。

When the wave wells up the regulation that the voltage is greater than the gas and in charge of, gas in charge of discharge earth connection too high voltage, Protect the apparatus systematically.

正常情况下，不会影响系统的工作

Under the normal situation, will not influence the systematic work
