IC693CPU352RR (1)采用变频器控制后启动风机时可以实现软启动,避免了启动时对电网冲击,可以有效地延长电气设备的使用周期。
(2)按需调节风量,调速范围宽且调速精度高,避免浪费。进行变频改造后,风机的风量通过变频调节电机的转速来实现,可以根据生产需要调节风量,避免了浪费。
(3) 降低了风机的工作强度,延长了使用寿命。进行变频改造后,大大降低了风机的机械强度和电气冲击,大大延长了风机寿命。
(4) 变频器具有短路、过载、过压、欠压、缺相等各种保护,有效地保护了电机。
(5)改善了现场工作环境,由于降低了风机的转速,风机噪声大大降低,深受现场工作人员的欢迎。
(6)在以后的新上项目中可以减少增速机及其油站,直接采用高压变频器控制,缩减了中间环节,节约了能源,提高了效率。
