TSXP57354M变频恒压供气

降低压缩机转速调节供气压力，是达到压缩机经济运行的有效方法，而变频调速方法，是一种调速方法。考虑在储气罐上安装一只压力变送器，将压力信号反馈到变频器的端子上，构成恒压供气系统，供气压力0.8MPa。本例选用一台KE300A-132kW变频器，压力变送气选用森纳斯DG13W=BZ-A，1.6MPa。

变频器控制第一台压缩机，给定调节用变频器上的操作键盘，变频器的多功能输出T1、T2分别接第二和第三台的压缩机的自耦减压起动器的起动/停止电路，这样可由变频器的输出控制另外两台压缩机的运行或停机。

手动运行时，第一台压缩机由变频器控制，第二和第三台的压缩机可用自耦减压起动器人工起动/停止。自动运行时，第一台压缩机首先变频运行，当变频器的输出频率已达到50.00Hz，供气量仍不足，变频器的输出节点T1、T2动作，起动第二和第三台的压缩机工作；如供气量大于给定值时，系统自动停止第二和第三台的压缩机工作，通过闭环调节可实现恒压供气。

氢气为可燃性气体，压缩机的工作场地有爆炸危险，KE300A系列变频器的防护等级为IP20，显然不能安装在有爆炸危险的场合。将变频安装在没有爆炸危险的配电房内，用远方控制盒在压缩机旁进行操作，远方控制盒也要考虑为本质。
