【摘要】 黑龙江省"十五"数字地震观测网络项目自2007年完成建设并开始运行,其中牡丹江地震台新增形变、火山测震台网等观测项目,密山台新增测震,大地电场等观测项目。台站运行期间,地震专业仪器设备出现设备故障及损坏情况,经过对台站技术系统的分析,判断牡丹江地震台和密山地震台由农电局供电的交流供电系统存在问题,本文分析了故障产生的原因,以牡丹江台为例并给出了解决办法,通过改造供电线路,2009年至今台站交流供电系统工作稳定,取得了良好效果。更多还原

【Abstract】 Since the digital seismological observation network project of the tenth five-year plan in Heilongjiang province ran in 2007,the deformation observation,volcanic earthquake observation and earthquake monitoring,telluric electricity field observation items have been separately started in Mudanjiang and Mishan Seismic Station.The professional instruments for earthquake observation were out of order or damaged during the operation period.By means of the analysis of the station’s technology system,it was estimated that there were problems in the exchange power system supplied by the local Power Supply Bureau.Taking Mudanjiang Seismic Station as an example,the causes of the power supply problems were analyzed in this paper.And after transforming the charging lines,the instruments have worked steady since 2009,which leads a good effect.更多还原
