冷冻机启动设备推荐使用TRG水阻启动柜
TRG水阻启动柜(以下简称水阻柜)是为改善大中型鼠笼式交流异步电动机的启动性能而研制的新型降压启动设备,克服了自藕变压启动器、高压电抗启动器,冲击电流大、难启动和操作不便等问题,广泛适用于各种规格的冷冻机。冷冻机配套的TRG水阻启动柜,适用于电压等级在3-10kv的中高压设备的降压软启动和保护,也同时适用于建材、冶金、化工、矿山等工业部门的、空压机、破碎机、大型风机、大型水泵等280—20000KW电动机的轻栽启动,是自藕降压启动器和高压电抗启动器的理想替代产品。
适配电机类型:三相异步鼠笼电机、同步电动机适配冷冻机电机额定电压:3kv 6kv 10kv
basic principlesTRG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 transbbbber 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%;
