在介绍本质安全电路中简单电容电路火花放电和简单电感电路弧光放电特性的同时,从实际电路出发,分析了电容电感复合型电路放电特性,提出了电容电感复合型电路在火花点燃试验中特定时间段内放电能量大于简单电容电路和简单电感电路放电能量,希望给本质安全电路设计提供指导性建议。
This paper introduces the spark discharge of simple capacitance circuit and arc discharge characteristic of simple inductance circuit in intrinsically safe circuit. At the same time, from the actual circuit, analyzes the discharge characteristics of capacitance-inductor composite circuit, and puts forward that the capacitance-inductance composite circuit can be used in spark ignition test for a specific time The discharge energy in the segment is larger than the discharge energy of the simple capacitor circuit and the simple inductor circuit, hoping to provide the guidance suggestion for the intrinsically safe circuit design.
