以前我们使用的地磁仪电源是由晶体管收音机稳压电源代用的,虽是成品,但用于地磁仪电源容量嫌小,器件容易损失,不能保证仪器长时间连续可靠地工作。交直流转换时,磁照记录的线条浓淡差异较大,影响了记录质量。为此需要设计一种适宜于地磁仪要求的稳压电源。DWK—1型稳压源就是为此而设计的。经过技术鉴定和台站试用,符合地磁仪使用的技术要求。本电源具备三项功能:一是提供稳定的直流电源;二是交直流电源自动切换;三是远距离操作控制。
In the past we used the geomagnetic power by the transistor radio power supply substituting, although the finished product, but for the geomagnetic power capacity is too small, the device is easy to lose, can not guarantee the instrument for a long time continuous and reliable work. AC and DC conversion, the magnetic strokes of the difference between the larger shades, affecting the recording quality. To do this, it is necessary to design a regulated power supply suitable for geomagnetism. DWK-1-type regulator is designed for this purpose. After technical appraisal and station trial, in line with the technical requirements of geomagnetic use. The power supply has three functions: First, to provide a stable DC power supply; Second, AC and DC power automatically switches; Third, long-distance operation control.
