矿用本质安全型远程中继电源设计

Design of mine-used intrinsically safe remote relay power supply

  • 摘要: 为满足井下超长工作面传感器的远距离传输需求,设计了矿用本质安全型远程中继电源。在本安电源与传感器之间并联一级输出为24 V的矿用本质安全型远程中继电源,可补偿单级24 V本安电源在供电电缆上产生的压差,从而延长本安电源的供电距离。测试结果表明,该中继电源可使24 V本安电源的供电距离延长至少2 km,且具有启动电流小、输出电压稳定、性价比高等优点。

     

    Abstract: In order to satisfy long-distance transmission requirements of sensor used on underground super long working face, a mine-used intrinsically safe remote relay power supply was designed. Parallel connecting a mine-used intrinsically safe remote relay power supply between the sensor and intrinsically safe power supply can compensate differential pressure on power supply cable of single 24 V power supply, and extend power supply distance. The test results show that the relay power supply can make power supply distance of 24 V intrinsically safe power supply extend at least 2 km, and has small start current, stable output voltage and high performance to price ratio.
