液体电阻起动器
 YRQ系列液体电阻起动器是为改善大中型绕线式交流异步电动机的起动性能而研制的新型起动
器，它是通过在电机转子回路串入液体电阻，自动无级调整电阻阻值使其由大变小最后为零，进而
实现电机降压无冲击地下滑起动。适用于建材、冶金等行业的球磨机、风机、轧机、破碎机、水泵
等70-6000KW电动机的重载起动。
性能特点
    。平滑起动：对设备无机械应力冲击，可延长电机和机械设备的使用寿命。
    。起动电流小且恒定，对电网无冲击。起动电流小于额定电流的1 .3倍。可以降低电机重载起
动对变压器容量的要求，减小一次性投资。
    。可连续起动5-10次，且具有点动功能。
    。可低压起动。只要电网电压能保证电机正常运行，就能保证顺利起动。
    。具有起动超时、超温、失压、超行程等多重保护功能。
    。结构简单、可靠、全部操作自动化、安装、维护方便。
订货须知
    订货时请提供以下资料：
    。电动机型号、额定功率、额定转子电流、转子电压、额定转速。
    。电动机拖动负载特性。
    。柜体表面颜色要求。
    。通讯接口要求。
    若用户有特殊要求请与我公司协商订制。
