摘要:
煤矿井下设备和仪器对于安全有着特殊的要求,电源模块是保证煤矿井下设备安全稳定运行的关键组成部件。基于矿用钻孔成像仪对供电电源可靠性、稳定性、多路可控的需求,提出一种矿用双路可控本质安全型电源模块的设计和研究。采用高转换效率、输出电压及输出电流可调节的低压差线性稳压芯片和高精度、可调节过压和过流保护集成芯片,结合电池组、升压、降压和二级保护等方式进行了电路设计,并通过试验验证了电源模块的可靠性和稳定性,测试结果表明,该设计电源安全、可靠、稳定。电源模块的最大短路电流、最大容性负载、最大感性负载均符合GB3836.4—2010的本安要求,能够满足CXK 12矿用钻孔成像仪的使用需求。
Abstract:
Coal mine underground equipment and instruments have special requirements for safety.Power supply module is a key component to ensure safe and stable operation of coal mine underground equipment.Based on the demand of mine borehole imager power supply for reliability,stability and multichannel controllability,a new design and research of dual-channel controllability intrinsically safe power supply module for mining is proposed.A voltage regulator chip and a protection integrated chip are adopted to design this circuit.The voltage regulator chip has low voltage differential linear,high conversion efficiency,and adjustable output voltage & current.The overvoltage and overcurrent of the protection integrated chip have high precision regulation.Based on the battery pack,step-up,step-down and secondary protection methods,the circuit is designed.The reliability and stability of power supply module are verified by the experiment.Test results show that the designed power supply is safe,reliable and stable.The maximum short-circuit current,maximum capacitive load and maximum inductive load of the power supply module meet the intrinsic safety requirements of the GB3836.4—2010,which can meet the requirements of the CXK12 borehole imager for mining.
