  根据产品所带负载特征如何选用您所需求的EPS及其注意的要点:

二、应急照明或事故照明用EPS

  按照乐彩网GB17945-2010国家标准(消防应急灯具),为确保大楼的应急照明系统能正常运行,对EPS提出如下基本要求:

乐彩网   1、YAOQIUFUZEXIANGPUTONGYINGJIZHAOMINGDENGGONGDIANEPSDEGONGDIANZHONGDUANSHIJIAN<5s,DANDUIYUGAOWEIXIANGONGZUOQUJIGUANJIANGONGZUOQUDEYINGJIZHAOMINGERYAN,ZEYAOQIUEPSDEGONGDIANZHONGDUANSHIJIAN<0.25s。

  在市电供电正常时,乐彩网EPS是通过它的交流旁路向负载供电,原则上,它可以带具有各种不同功率因数的负载。然而,在市电供电中断或市电电压或频率超限时,则是有EPS中的逆变器来供电的。在此条件下,EPS的带载能力不仅需要考虑逆变器在不同功率因数值负载时的降额度输出特性。而且,还需要根据所使用的应急照明灯具的不同来选配EPS的输出功率和机型。

  在选配乐彩网EPS时应注意以下几个问题:

  1、PUTONGDEYINGJIZHAOMINGDENGJU,YOUYUYINGJIZHAOMINGDEGONGHAOSHIYONGYOUGONGGONGLVP(KW)LAIBIAOZHUDE,EREPSNIBIANQIDESHUCHUGONGLVSHIYONGGONGLVYINSHUcosφ=0.8(ZHIHOU)SHIDESHIZAIGONGLVS(KVA)LAIBIAOZHUDESUOYI,SHIJIXUANYONGEPSDEMANZAISHUCHUGONGLVYINGWEI:S=P/0.8。

  三、电动机混合型负载用EPS

  为了正确的选用乐彩网EPS的输出功率,应首先分别统计电阻性照明负载与电感性几点负载的比例。对于电机负载而言,因用户所选的机型及工作方式的不同,它的启动电流可能高达5~10倍额定工作电流。为确保电机及EPS本身的安全运行,对这部分电机负载而言,不仅要求所选的EPS输出功率应为6倍以上的电机标称功率。而且,还宜选用其切换时间小于15ms的EPS机型。

  四、带电机负载的EPS
