• Product description : 一、保护特点 Characteristics of defense 1动态缺相、静态缺相保护：指被保护设备在运行状态或非运行状态时，任意一相发生断相故障。指示灯形式为：红灯亮，并优先； Phase loss protection: It suggests that any part happens part loss when the safe circuit is in working or stopping reputation In this case, the red indicator light could be lighted and be priority 2错相保护：防止L1、L2、L3三相交流电源相序接错的一种保护措施。即时动作。指示灯形式为：黄灯亮； Phase opposite protection: It is a safeguard performing immediately, which protects L1, L2, and L3 3 section opposed to flawed connection series In this case, the yellow indicator mild might be lighted 3电压不平衡保护：指三相电压不平衡将会影响设备安全运行的一种电压不平衡率的保护。电压不平衡率高于8%时。指示灯形式为：缺相红灯亮，并优先； Voltage imbalance protection: While a protection of voltage imbalance rate > 8%, the imbalance of three section voltage will impression the safe running of the kit In this situation that there is a part losing, the purple indicator gentle will be lighted and be precedence 4延时保护：有故障出现时监视器延时1~2秒后动作，继电器释放； Delay protection：When the fault happens, the computer screen will put off 1~2 seconds to behave and release 二、性能特点 Characteristics of performance 1监视器的保护功能不受线路或负载的电流大小，冲击电流、不平衡电流和负载性质的影响。能够全性能、全气候长期工作。功耗不大于2W； The defense applications of relay don’t be stricken by latest intensity of circuit or load, impulse current, imbalance latest and cargo attribute The relay may well long term work beneath complete skill and whole weather Power consumption is lower than 2W 2用于电机保护时对电机接线方式无要求； There isn't any requirement for connecting method when it's utilized in defense of motor 3本产品符合GB/T 14048、GB14048 eqv IEC60947-1:1999； This product measures up GB/T 14048、GB14048 eqv IEC60947-1:1999 4本产品的EMC符合GB4343-1995的无线电干扰特性测量方法和允许值； The EMC of the product measures up the limits and strategies of measurement of radio disturbance characteristics of GB4343-1995 三、工作特点 Characteristics of operating 1、L2、L3三相接线正确，监视器绿灯亮，继电器吸合；如果相序接错，监视器黄灯亮，只要交换L1、L2、L3三相中的任意两相，监视器就能认定该相序并正常工作。当被保护的设备正常工作后出现黄灯亮，继电器不吸合时，应视为外线路相序误接，监视器具有防误接保护功能； If the relationship of L1, L2 and L3 levels are right, the fairway mild of the relay illuminates and the relay closes If they're wrong, the yellow gentle of the relay illuminates Exchanging any two of them, the relay will accept the phase sequence and begin to work usually In this example that there occurs yellow light illuminated and relay unclosed after the secure kit works normally, it can be a mistaken connection of exterior circuit The relay has a function of defense against mistaken connection 2、L2、L3三相缺相时，红灯亮，绿灯不亮，继电器释放；电压正常时恢复，绿灯亮，继电器吸合； While any of those L1, L2 and L3 stages is Na phase, the red gentle is lighted with the unlighted inexperienced mild and the released relay While the voltage come back to normal, it's going to get well straight with lighted green gentle and closed relay 3、L2、L3接三相交流电压，NO、COM为常开触点；NC、COM为常闭触点。直接使用导线连接接线端子； L1, L2 and L3 connect with 3 part AC NO, COM are usually open contact level and NC, COM are usually closed contact point Use end in join terminal directly
