可适用于南京贝特、上海川源、蓝深集团、扬子江泵业、南京布鲁克林或其它类同类的所有潜水泵保护器。
1.2.原理根据QW2型保护器长年工作在水下的结构与特性在对QW2型保护器的保护装置中必要加入油室泄漏保护与电机超温保护：油室泄漏保护：在潜水泵保护器油室内置入水份检测电极，在油室中如果出现有水份超限时电极出现信号跳变，QW2潜水泵保护器能检测到此信号的变化，而停止QW2潜水泵保护器运行并以故障指示。
电机超温保护：在潜水泵保护器三相电机绕组每相上安装135℃的PTC热敏电阻，在任一相绕组出现温度上升到135℃±5时，电阻值出现跳变，QW2潜水泵保护器能检测到此信号的变化，而停止QW2潜水泵保护器运行并以故障指示。
电机过载保护：在潜水泵保护器三相电机运行回路上每相线上串入相对应用电流的热继电器，一旦电流过大，热继电器会状态跳变，QW2潜水泵保护器能检测到此信号的变化，而停止QW2潜水泵保护器运行并以故障指示。
低水位保护：在潜水泵保护器工作的水池中，使用液位检测器检测水位，但水位低于潜水泵保护器工作的水位时，液位检测器会状态跳变，QW2潜水泵保护器能检测到此信号的变化，而停止QW2潜水泵保护器运行并以低水位指示。
1.3.主要性能传感器供电：传感器DC12V供电。
供电电源变压器隔离。
信号输入：超温信号：电机超温保护。
泄漏信号：油室泄漏保护。
输入回差控制：±2%。
潜水泵使用规范
内蒙古××煤化科技有限公司潜水排污泵使用规范编写：审核：审定批准：日期：潜水排污泵使用规范1、长期停用的潜水电泵再次使用前，应拆开最上一级泵壳，盘动叶轮后再行启动，防止部件锈死启动不出水而烧坏电动机绕组。
这对充水式潜水电泵更为重要。
2、潜污泵在无水的情况下试运转时，运转时间严禁超过额定时间。
吸水池的容积能保证潜污泵开启时和运行中水位较高，以确保电机的冷却效果和避免因水位波动太大造成的频繁启动和停机，大中型潜污泵的频繁启动对泵的性能影响很大。
3、安装漏电保护器漏电保护器也叫保命器，它的作用从“保命器”这三个字就可以理解。
因为潜水泵在水下工作，容易漏电造成电能损失甚至引发触电事故。
如果装有漏电保护器，只要潜水泵漏电值超过漏电保护器的动作电流值(不超过30毫安)，漏电保护器就会切断潜水泵的电源，避免漏电浪费电能，确保安全。
4、电源电压异常莫开机，当相电压低于198伏，线电压低于342伏时，潜水泵电机转速下降，当达不到额定转速的70%时，启动离心开关会闭合，造成启动绕组长时间通电而发热甚至烧坏绕组和电容器。
相反，电压过高引起电机过热而烧坏绕组。
因此，潜水泵在作业中，操作者必须随时观察电源电压值，若低于额定电压10%以下，高于额定电压10%以上，应使电机停止运转，找出原因并排除故障。
5、莫让潜水电泵长期超负荷工作为避免潜水电泵长期超负荷工作，不要抽含沙量大的水并随时观察电流值是否在铭牌上规定的数值，若发现电流过大，应停机检查。
另外，电泵脱水运行的时间不宜过长，以免使电机过热而烧毁。
6、避免频繁开关，不要频繁地开关潜水泵，这是因为电泵停转时管路内的水产生回流，若立即开机，会使电机负载启动，导致启动电流过大而烧坏绕组。
另外，潜水泵过于频繁开、停将损坏承受冲击能力较差的零部件，并带来整个电泵的损坏。
由于启动时电流很大，频繁启动也会烧坏潜水泵电动机绕组。
7、电机的旋转方向要正确应搞清电机的旋转方向，现在有许多类型的潜水泵正转和反转时皆可出水，但反转时出水量小、电流大，其反转时间长了会损坏电机绕组。
人民电器 RDM1L系列漏电断路器(透明壳) 使用说明书
R D M1L剩余电流动作断路器符合标准：GB/T 14048.2警告1 漏电断路器对同时接触被保护电路两线引起的触电危险不能进行保护，使用时请务必注意。

4 严禁湿手操作漏电断路器，否则可能发生电击事故。
注意1 漏电断路器安装场所应无爆炸危险、无腐蚀性气体，并应注意防潮、防尘、防震动。
2 漏电断路器安装位置应避开强电流电线和电磁器件，避免磁场干扰。
3 四极漏电断路器上接线端子必须接入中性线，以利于电子线路正常工作。
安装时必须严格区分中性线(N)和保护线（PE），经过漏电断路器的中性线不得作为保护线, 不得重复接地或接设备外露可导电部分。
保护线不得接入漏电断路器。
4 漏电断路器的漏电、过载、短路保护特性均由制造厂整定，在使用中不可随意调整，以免影响性能。
5 绝缘测试本漏电断路器出厂前已按标准规定进行绝缘测试，因漏电断路器带有电子线路板，安装前如进行复测，必须按如下步骤：a) 用500V DC兆欧表；b) 在漏电断路器处于断开状态时, 对进出联结板1-2、3-4、5-6之间分别进行；断路器处于闭合状态时，严禁对漏电断路器的1-5或2-6之间进行测试；c) 绝缘电阻应不小于10MΩ。
1 用途及适用范围RDM1L系列剩余电流动作断路器(以下简称断路器)，主要适用于交流50Hz，额定工作电压为400V,额定电流至800A的配电网络中，用来对人提供间接接触保护，也可用来防止因设备绝缘损坏, 产生接地故障电流而引起的火灾危险，并可用来分配电能和保护线路及电源设备的过载和短路, 还可作为线路的不频繁转换和电动机不频繁启动之用。

电子潜水泵漏电断路器使用说明
1.首先使用螺丝刀将产品接通电源。
2.其次按下产品上面的试验按钮，观察保护器是否跳针，若跳闸，说明产品是完好的，若没有跳闸，说明产品是坏的，是无法起到缺相保护的作用的。
3.然后将保护器上面的闸刀重新开启，即将闸刀向上拉即可。
4.最后将产品的输出端接三相用电设备即可，然后就能够正常使用！
漏电断路器也叫保命器，它的作用从“保命器”这三个字就可以了解。
因为潜水泵在水下作业，容易漏电形成电能损失甚至引发触电事端。
假如装有漏电保护器，只要潜水泵漏电值超过漏电保护器的动作电流值(一般不超过30毫安)，漏电保护器就会堵截潜水泵的电源，防止漏电糟蹋电能，确保安全。
潜水泵注意事项：不要频繁地起停潜水泵，这是因为电泵停转时会发生回流，若立即开机，会使电机负载发动，导致发动电流过大而烧坏绕组。
因为发动时电流很大，频繁发动也会烧坏潜水泵电动机绕组。
