为了进一步提高地震台站现有仪器的技术性能,充分现有观测仪器及时获得连续、可靠、准确的第一手资料,针对地磁仪时号钟的缺点,考虑到SY2石英钟准确、稳定、可靠的优点,对地磁仪时间服务系统作了一些改进,试制了石英钟时号变换器。地磁时号钟原来是用机械闹钟外加一对时号触点改装而成,到整点时刻,触点闭合,接通时号灯供电回路,时号灯发亮,从而在照象纸上打出时号来。但机械闹钟的精度较低,而
In order to further improve the technical performance of the existing instruments at the seismic station and to fully obtain the continuous, reliable and accurate first-hand information of the existing observing instruments in time, in view of the shortcomings of the geomagnetic hour-counting clocks, taking into account the accurate, stable and reliable SY2 quartz clocks Advantages, made some improvements to the geomagnetic time service system, trial production of quartz clock time converter. The geomagnetic clock was originally a mechanical alarm clock plus a pair of HHD contacts modified to the whole point of the moment, the contact closed, when connected to the light power supply circuit, the hour light shining, which shot in the photographic paper Times to come. However, the accuracy of mechanical alarm clock is low, however
