研究结果表明,输出保护电路的设计影响到整个电源的性能,因此,应该熟悉本质安全电源的结构、检测标准、火花试验装置等相关文件和标准。在此基础上,设计保护电路的结构、选择反应速度较快的电子元器件用于保护电路主要元件。使得保护电路的反应速度满足国家标准规定的要求。
关键词:保护电路、本质安全、本质安全电源、国家标准。
At present, China's production and use of essential safety-DC power supply are large linear power supply, output to protect its most traditional circuit simulation protection circuit. Therefore, intrinsically safe power supply capacity generally quite low. As China's coal mine mechanization and increase the degree of automation, intrinsically safe electrical equipment in underground surveillance, communications, signals, instruments and automation system becomes more widely. As a result of these equipment constantly in use, mining DC Power demand has been increasing steadily, and Meanwhile the capacity of its set higher requirements. In a certain sense, flameproof and intrinsically safe power output capacity of the output depends on the size of the protection circuit of reaction time. The issues against mining output power of the security protection circuit design, China to adapt to the rapid development of the coal industry needs, and has important practical significance. T
