软启动液位控制方案GKYX1A

软启动柜的主要用途及使用方法一）用途软起动柜，主要用于接收液位控制仪（器）所输出的高、低水位控制信号，控制液泵电动机的自动开起与停止，其控制形式有全压起动、降压起动、软起动、变频控制等。

（二）调试与使用方法本系列控制柜（箱）控制回路中，既设自动控制亦有手动控制，还具备过流、过压、欠压、缺相保护及事故报苦功能，本产品使用前，必须按电气原理图复核后接线，按照电动机实际要求调整相应元件设定值，然后起动。

1 、自动操作：接通电源，电源指示灯亮，将转换开关转至“自动”位置，检查控制柜（箱）所控制的电机是否按液位控制仪的指令动作。

当液位达到控制液位时，对应液位指示灯发光，相应的限位控制继电器常开触点自动闭合，二次控制回路自动接通，电机起动，同时运行指示灯亮。

当水位达到停止水位时，对应的指示灯发光，液位测控仪的对应限位控制继电器常闭触点断开，二次控制回路开路，电机停止工作，运行指示灯熄灭。

2 、手动操作：接通电源，电源指示灯亮，将转换开关转至“手动”位置，按下起动按钮，电机开始运转，运行指示灯亮，按下”停止”按钮，电机停止运转，其运行指示灯熄灭。

3 、不论采用何种控制方式，当达到极限水位时，其超限水位信号触点接通，二次控制回路失电，使电机停止运转，并发出声光报苦信号。

在电机运行过程中如有事故出现，事故指示灯亮，电铃自动报苦，这时，按下停止按钮，迫使电机停止工作。

软起动器的日常维修与检查∙平时注意检查软起动器的环境条件，防止在超过其允许的环境条件下运行。

注意检查软起动器周围是否有妨碍其通风散热的物体，确保软起动器四周有足够的空间（大于150mm）。

∙定期检查配电线端子是否松动，柜内元器件有否过热、变色、焦臭味等异常现象。

∙定期清扫灰尘，以免影响散热，防止晶闸管因温升过高而损坏，同时也可避免因积尘引起的漏电和短路事故。

清扫灰尘可用干燥的毛刷进行，也可用于皮老虎吹和吸尘器吸。

对于大块污垢，可用绝缘棒去除。

若有条件，可用0.6MPa左右的压缩空气吹除。

起动加速时间在0—30S之间，由用户自行调节。

起动斜坡加速期间，输出至电机的电压不断上升，当软启动器的控制器检测到电动机已达到额定转速状态，则输出电压将自动切换到全电压。

（若设定的起动时间为30S，在20S的时候如果电动机已达到额定转速，电机端电压已达到全电压，则不必等到30S）2．限流起动：限流起动顾名思义，限制电机的起动电流，该方式为电动机提供一固定电压的降压起动。

限流水平可由用户在电机满载电流的500-600%间调节，限流起动时间0—20S由用户设定。

在起动过程中，当软起动器的控制器检测到电机的额定转速时，输出电压将自动切换成全压输出，这点与软起动方式有些区别：软起动过程电压是无级不断增加的；而限流起动是始终以一固定电压起动的。

3．全压起动：该方式同一般设备的启动相同，一般来说，既然选用了软启动器就不太会选用该方式进行起动。

4．可选择的突跳起动：该起动功能一般是附加于软起动方式或限流起动方式之中，为电动机起动提供一个大提升转矩以克服负载惯性，突跳时间可由用户在0.0—2.0S之间设定。

我厂采用的软起动方式主要有以下两种：1．限流加突跳起动方式：该方式主要用于PVC的水环压缩机、抽风机、鼓风机和排渣泵等设备，因为这些设备的电机容量较大，起动电流较大，其供电线路也较长，采用限流起动，可减少对配电室母线电压的影响，以免造成当大设备启动时，母线压降大，使照明及其他设备失电跳闸的情况发生。
