矿用隔爆兼本安型ia电源电路设计与检测

Design and Test Method of Mining Flameproof and Intrinsically Safe Power Supply Circuit for Level of Protection "ia"

矿用隔爆兼本安型电源是矿用电气产品的重要电源供给,其设计和检测都是矿用电气产品的设计和检测重点。该文通过三重化的电子电路设计后串限流电阻的方式进行保护,并通过瞬态能量测试方法检验其输出参数的本安符合性,试验结果显示,设计可行,检验结果在允许范围内。

Mine flame-proof and intrinsically safe power supply is an important power supplyfor electrical products, and its design and testing are central issue. After triple string electronic circuit, resistance in series is to limit the current. The circuit is tested by the transient energy test method, and the test result show that the design is feasible, the test result is within the allowable range.
