Power Supply Design of Intrinsically Safe Gas Detector

以本质安全型便携式气体探测器为基础,对其电源部分的充电、放电电路的本安设计进行讨论,提出一种符合本质安全要求的电源管理设计方案。

Intrinsically safe gas detector is widely used in petroleum,chemical,pharmaceutical and other process industries,which is of great significance to ensure industrial safety in production.Based on the intrinsically safe portable gas detector,this paper discusses the intrinsically safe design of the charging and discharging circuit of its power supply,and puts forward a power management design scheme meeting the intrinsically safe requirements.
