商品详细描述
朗菲相序保护器是一种应用大规模数字集成电路、无变压器设计的新型高科技专利产品(独家生产，如有雷同纯属仿冒) 通用性强(3Ph220V～500V 50Hz/60Hz均可使用)体积超小，外观非常漂亮是取代施耐德相序保护器(RM4-TG20)、ABB、西门3TK2825-1BB40)、日本欧姆龙(OMROM)及其它国产相序保护器(XJ3、XJ5系列)JVR等相序保护器 这款相序保护器为最理想的产品。 LF-RD6系列相序保护器操作指南（1）把三相电源的三相电线，分别接入LF-RD6相序保护器的L1、L2、L3（2）再将出现端分别对应的L1、L2线，接入出现端（28、25或者18、15）。（3）接好线之后通电，这时电源（红）灯，正常（绿）灯，出现亮灯状态。则表明接线正确，线路正常 故障指示信息当正常接入线之后，两个灯是亮灯状态的时候。当线路中出现错相、缺相、相序不平衡时候，正常（绿）灯，就会熄灭。这时应该检查电路中是否出现故障当工程师排除故障之后，相序保护器会呈现正常状态。
一、保护特点 Characteristics of protection
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，绿灯熄灭；
Phase loss protection: It means that any phase occurs phase loss when the protected circuit is in running or stopping status. In this case, the red indicator light will 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：红灯亮，绿灯熄灭；
Phase opposite protection: It is a safeguard acting immediately, which protects L1, L2, and L3 three phase against wrong connection sequence. In this case, the yellow indicator light will 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20%时。指示灯形式为：红灯亮，绿灯熄灭；
Voltage imbalance protection: While a protection of voltage imbalance rate > 20%, the imbalance of three phase voltage will affect the safe running of the equipment. In this case that there is a phase losing, the red indicator light will be lighted and be priority.
4.延时保护：有故障出现时监视器延时1~3秒后动作，继电器释放；
Delay protection：When the fault happens, the monitor will delay 1~3 seconds to act 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 protection functions of relay don’t be affected by current intensity of circuit or load, impulse current, imbalance current and load characteristic. The relay could long term work under full capability and full climate. 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 is no requirement for connecting method when it is used in protection of motor.
3.本产品符合GB/T 14048.1-2000、GB14048.5-2001 eqv IEC60947-1:1999；
This product measures up GB/T 14048.1-2000、GB14048.5-2001 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 methods of measurement of radio disturbance characteristics of GB4343-1995.
