目前大多数地磁台所使用的地磁配电装置，均是北京地质仪器厂７０年代生产的配电盘。这种配电设备不但功能较少，而且由于年长日久，元件已趋于老化，工作中故障率较高，给台站观测质量带来一定的影响。为改善不足，保障台站的观测质量，乌鲁木齐地震台于１９９７年初与新... At present, most geomagnetic units used by geomagnetic power distribution equipment are produced by Beijing Geological Instrument Factory in the 1970s. Such distribution equipment not only has fewer functions, but also has a higher failure rate due to aging of the components as time goes by, which has an impact on station observation quality. In order to improve the inadequacy and ensure the observational quality of the station, Urumqi Seismic Station in early 1997 and new ...
