      2)电网集控管理(人机界面)

      电网的人机界面,我们提供丰富的可选测控功能供用户选择,包括:

      a)电网状态、数据集中监测;

      b)电网各开关状态集中控制;

      c)到人的短信状态报警及状态通报功能;

      d)基于互联网的远程抄表、状态监测、控制功能;

      2、电力拖动

      1)高炉主抽起动方案

      钢铁行业高炉主抽风机,尤其是新上高炉,所配高压电机一般功率很高,为减少电网投资,要求较小的起动电流;同时,由于在工艺上的特殊性,要求可靠性非常高。针对这种需求,我们向广大客户推荐使用我公司的电磁调压补偿软起动系列产品(链接),他具有起动时电网电流、电网压降小、可靠性高、起动过程平稳、起动重复性好的特点,非常适用于大功率、超大功率高压电机的软起动。其典型的一次解决方案图如下,用户可根据不同需要选择:

     

     

      本方案同时适用于制氧、烧结及其他工艺中的大功率高压电机的起动;

      对于预算有限,电网条件稍好的客户,也可以选用水电阻调压补偿软起动产品(链接),或较小功率电机且电网条件很好的客户,可使用传统的软起动产品:电磁调压软起动装置、高压固态软起动装置、水电阻软起动装置等。

      2) 烧结主抽起动方案

      烧结主抽风机一般起动阻力距很大,起动时要求电机输出较高的转矩,因此,起动电流大,起动时间长。为保证最好的起动效果,既控制电机电流在限定值以内使电网压降不至过大,又将起动时间控制在最小,就需要软起动设备控制电机电流从起动开始到结束尽量保持在设定值,减少爬坡和下降时间。针对这种工况需求,我们在电磁调压和高压固态设备上使用了我公司专有的智能化起动模式,通过软件人工智能预判,最大程度的减小电流爬坡和回落时间,使电机在设定的电流值上完成整个起动过程,达到最佳起动效率和最小起动时间。对于电网较小的客户,我们推荐使用电磁调压补偿软起动设备,能更好的控制电机起动时电网压降,减小起动时间,减小负荷机械冲击,降低电机发热,保护电机和负荷。

      3) 喷煤、连铸等工艺上的皮带机起动方案

      皮带机通常要求频繁起停,传统的液电阻软起动设备不能满足要求。对于这类负载,我们采用电磁调压或高压固态软起动设备来完成其起动,这两类产品单次起动温升1-3℃,能满足多次频繁起动要求,特别适合皮带机等需要频繁起动的设备。

      (案例链接:酒钢喷煤皮带机起动方案)

      4) 制氧、炼铁、连铸、焦化、喷煤、高炉、烧结等各工艺上的抽风机、除尘风机、循环水泵、氨水泵、破碎机等的起动方案

      我们有丰富的各种特性负载软起动方案提供经验,提供品类最全、质量最优的软起动设备,包括电抗器起动、水电阻类、高压固态、电磁调压等各种软起动方式,满足各种不同特性的负载软起动要求。

      5) 各类低压电机节能控制、起动方案

      对各类低压电机,我们提供变频器和低压固态软起动两种拖动方式。

      对于运行时效率较低的风机、水泵及其他类负载,我们建议使用低压变频器进行拖动,既能很好的完成软起动功能,同时,通过变频运行,节能降耗;

      对于运行效率较高的设备,或需要经济型软起动方案时,我们提供低压固态软起动产品,以最低的成本,可靠的完成电机起动过程,减小电网压降和负荷冲击,保护设备。
