摘　　要：基于国家标准GB/T 3836.32—2021中的Power-i检测系统分析了模拟负载特性,得到负载直流和交流状态下的两种不同特性,直流状态时的软起动特性及电路中非线性元件的等效电路各参数之间的关系,软起动时间与电路参数间的量化特征,交流时体现出的回转器特性。经过Multisim仿真验证了两种特性的正确性,对于Power-i装置在本质安全电路的应用具有重要意义。Based on the Power-i detection system in GB/T 3836.32-2021, the artificial load characteristics are analyzed, and two different characteristics of the load under DC and AC conditions are obtained. The soft start characteristics under DC conditions, the relationship between the parameters of the equivalent circuit of the nonlinear components in the circuit, and the quantitative characteristics between the soft start time and the circuit parameters is introduced. The gyrator characteristics reflected in AC. The two characteristics is verified by Multisim simulation, which are of great significance for the application of Power-i device in intrinsically safe circuits.
