CJX4-6021Kd 切换电容器交流接触器々CJX4-kd系列切换电容器接触器
CJX4-kd Range Contactor for Capacitor Switching
一、用途 APPLICATION
CJX4-kd系列切换电容器接触器（以下简称接触器）主要用于交流50Hz（或60Hz）， 额定绝缘电压为690V， 在AC-6b使用类别下，额定工作电压为400V时额定工作电流至87A的低压无功功率补偿设备中，通断低压无功功率补 偿用的电容器组，用以调整电系统的功率因数COSΦ值。接触器附有抑制涌流 装置，能有效地减少合闸涌流对电容器组的冲击和降低操作过电压。
CJX4-Kd range contactor for capacitor switching in used in AC 50Hz(or
60Hz), rated insulation voltage 690V, rated current is up to 87A under rated voltage 400V and category AC-6b of low-voltage no power compensation device, for adjust power factor COSΦContactor attached inhibit flow device that can effectively reduce impact from trip flow and reduce operation over- voltage.
二、结构特点 STRUCTURE FEATURE
△ 接触器为防护式，动作机构为直动式，触头为双断点。
Contactor is protection type, direct-moving and double breaking contact terminals;
△ 接触器由一台CSC1系列交流接触器，一台转换触头组和六根限流电阻线等零部 件组成，转换触头组挂接在CSC1系列交流接触器的上方，主触头系统分上、下 两层布置，上主触头接通瞬间后自行断开复位，下主触头继续闭合到位。 Contactor composite by a GSC1 AC contactor、 a conversion contact group、 six limiting current resistor line and other component parts, conversion contact group articulated on the above of GSC1 range AC contact, the main contact system arranged on up-low level. Up main contact disconnect and reset after making, the next main contact contains closed reset.
△ 在接触器两侧可加装辅助触头组（F3－20d1）以增加辅助触头对数。
Both sides can be added auxiliary contact （F3－20d1） for add the volume of auxiliary contact;
■ 触头数量：Contact volume
△ 接触器具有三对常开主触头，每对主触头分上、下两层，每对上主触头与两根 限流电阻线串联后与一对下主触头对应并联。接触器本身还具有两对辅助触头
（上层一对，下层一对，仅CJX4-25kd～40kd）或三对辅助触头（上层一对， 下层两对，仅CJX4-50kd～125kd）。
Contactor has three pairs of normally open main contact, every main contact arranged to upper and lower level, each upper main contact series with limiting resistor line, than counterparts with one lower main contact. Contactor itself also has two pairs of auxiliary contacts (one pair upper and one pair lower, only to CJX4-25kd～ 40kd), or three pairs of auxiliary contacts (one pair upper and two pairs lower, only to CJX4-50kd～125kd）.
△ 本系列产品的安装尺寸均与GSC1-d系列交流接触器对应相同。
Installation dimensions of the range product, all small GSC1-d range Ac contactor.
三、工作原理 WORKING PRINCIPLE
当控制回路通电后，接触器吸合，串入限流电阻线的上主触头先于下主触头 接通，从而达到抑制涌流作用，完成后瞬间断开复位，其间下主触头进入正常 工作，而断开回路时则由下主触头完成，各司其责。因限流电阻瞬间接入，所 以不会造成长期的电力浪费和烧损电阻线等现象。
When control circle is making, the contactor will pull in, the upper main contact with limiting resistor line making before the lower main contact, to achieve to inhibit flow, after that, the upper main contact breaking instantly and reset. At the same time, the lower main contact start normally working, lower main contact should complete breaking circle. All have themselves responsibility. Because of the limiting resistor instantly accession, it will not cause the phenomenon of long-term electricity waste and burning resistance line.
四、工作条件和安装条件
WORKING CONDITION AND INSTALLATION WAY

△ 周围空气温度：-5℃～ 40℃，24小时的平均值不超过 3 5℃。
Ambient temperature: -5℃～ 40℃. Average temperature ≤ 3 5℃ in 24H;

△ 安装地点的空气相对湿度在较高温度为 40℃时不超过50%，在较低温度下可以 有较高的相对湿度湿月的月平均较低温度不超过 25℃，该月的月平均较大相 对湿度不超过90%；由于温度变化发生在产品上的凝露情况必须采取措施。 Relative humidity is not exceeding 50% at the maximum ambient temperature 40℃ . With lower temperature, higher humidity would be permitted. And average maximum relative humidity ≤ 90% in the most humidity month, at the same time, the average minimum temperature should ≤ 25℃, and should give consideration to dews on the good surface,which would appear due to temperature change.
△ 接触器应安装和使用在无摇摆、冲击和振动的地方。
Contactor should be installed at no significant sharking or vibration place.
