YLQ水阻启动柜的基本工作原理
高压液体电阻由具有负温度特性的三相平衡液体电阻组成,当该电阻通入电流时,通过改变动,定极板之间距离从而使导电液体中串入电机定子回路中的电阻值无极减小,从而实现鼠笼式大中型电动机的轻载平滑启动。
1、启动电流小且恒定,对电网无冲击;启动电流不大于额定电流的3.5倍,因此可以降低电机重载启动对变压器容量的要求,减少一次性投资;
1. The starting current is small and constant and has no impact on the power grid; The starting current is not more than 3.5 times of the rated current, so that the requirement on transformer capacity for heavy-duty starting of the motor can be reduced, and one-time investment can be reduced;
2、平滑启动,减少对机械设备的冲击,可延长机械设备及电机寿命30%左右;
2, smooth start, reduce the impact on mechanical equipment, can prolong the service life of mechanical equipment and motor by about 30%;
3、热容量大,可连续启动3~4次;
3, the heat capacity is large, and can be continuously started for 3 to 4 times;
4、启动时,电机功率因数高,无谐波污染。
4. When starting, the motor has high power factor and no harmonic pollution.
5、结构简单,维护方便,可靠性优于电抗、自藕降压启动器。
