实用避雷地网工程的实施与改进技术

Improving of lightening arrester ground net

海南省琼北地区为我国雷击高发生区，野外测试仪器设备的安全保护问题极为重要。根据琼北遥测台网建台布局要求及台网子台所处的地理位置，气候环境等特点，自行设计了适应于遥测子台的避雷地网工程。实施中改进了地极的埋设和减阻剂的使用方法，大大降低了地极的接地电阻率。用此项改进技术实施的其它几个避雷地网工程，均达到和超过设计指标──接地电阻值小于４Ω。

The Northern area in Hainan Province is high lightening stroke area in China. Safety measures of field equipments are very important. According to features of layout requirement of N -Qiong telemetry network, geographical location of the substations, climate environment etc, we have designed a project of lightening arrester net suited to telemetased substations. In practice, ground connection resistance of the electrode is mostly decreased by improving buried method of the electrode. The several lightening arrester nets that have been put into effect by using the improving technology, all come up to or exceed the design target the ground connetion resistance is less than 4Ω.
