On Some Details of the Intrinsically Safe Circuit Design
介绍了工作在危险区域中的本质安全电路通过阻止工作在危险区域中的仪器和低电压电路释放出足够的能量即限制超过标准的以电压和电流形式存在的电能而使电路达到本质安全的原理。阐述了模拟量输入输出和数字量输入输出的安全栅是如何保证各种应用是本质安全的。最后给出了本质安全系统的接线、安装、接地维护和故障诊断等细节。
The article presents that the intrinsically safe circuit can stop the instruments and low voltage devices such as thermocouples, analog I/O, digital I/O working in the hazardous area from emitting excessive energy which exists in the forms of electric voltage or current and maintain the working devices safe intrinsically by using intrinsic safe barrier and gives some information on the details of wiring, installing, rounding, sealing, maintaining and detecting of the intrinsically safe system .
