CJX4-kd系列切换电容器接触器的工作原理
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.
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;
△ 安装地点海拔不超过2000m。Elevation ≤2000m
△ 安装地点的空气相对湿度在最高温度为+40℃时不超过50%,在较低温度下可以 有较高的相对湿度最湿月的月平均最低温度不超过+25℃,该月的月平均最大相 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显著摇摆、冲击和振动的地方。
Contactor should be installed at no significant sharking or vibration place.
△ 接 触 器 应 按 正 常 位 置 安 装 , 安 装 面 与 垂 直 面 倾 斜 度 不 超 过 ±30° , 安 装 可 采 用 螺 钉 安 装 或 卡 装 在35mm或
75mm安装轨上。
Installed according normal place, the tilt gradient with vertical face ≤ ±30°, can mounted by screw or by
35mm、 75mm standard rail.
