ARIES采集站的加电过程及四级雷电保护原理

ARIES仪器野外采集站单元采用了分布式供电,没有常规的电源站。在采集站内提供了独特的加电方式:若采集站没收到仪器指令,即使接通电瓶仍处于待机状态,不会给传输电路和模拟电路供电;收到仪器指令后,又能迅速接通排列上所有采集单元的供电系统,这样既可以最大限度地节约电瓶能量,又确保了采集设备的及时供电。为保护电器设备免遭天电破坏,采集站内还设计了完备的四级雷电保护电路。本文详细地介绍了ARIES采集站的加电过程和雷电保护措施,旨在为检修采集站的各类电源故障提供理论依据。

Introduction of the power-on process of ARIES acquisition station and the working principle of 4 stage lightning protection

The acquisition unit RAM of ARIES system uses distributed power supply to replace the conventional power station. These is a special way in the RAM to power-up： if the acquisition station did not receive instrument instruc- tion, even on the battery is in the standby state, then the transmission circuit and analog circuit will not power-on; but if the acquisition station received the instrument instruction, all acquisition units will be powered-on timely. This way can save the battery energy maximum. Four stage lightning protection circuit is designed to avoid the elec- trical equipment from the danger of thunder. This paper mainly describes the power up process and the lightening production measures of RAM as well as provides a theoretical basis for the maintenance of all kinds of power failure of acquisition station.
