摘要
云南是我国强震动观测台网分布较密集的地区,拥有强震动观测台站近300个,台网年平均正常运行率达99%以上。通过介绍云南强震动台网中台站特殊的供电方式及其原理、供电设备、加速度计和强震动记录器常见故障及维修方法,以期对其它地区强震动台网的维护有一定参考价值。
There are more than 300 strong earthquake stations in Yunnan, where displayed a dense strong motion ob- servation network in China. After observing for many years, the average annual normal operation rate of strong motion observation network have reached more than 99%. We introduce the special power supply mode and its working principles, power supply equipments of strong motion stations and the common troubles and mainte- nance method of accelerometers and strong motion recorders in strong motion seismic network in Yunnan. It could provide reference value for the maintenance of strong motion seismic network in the other areas.
