Intelligence fan power saving device

The utility model provides an intelligence fan power saving device, include: start cabinet, power saving device, PID controller and start chain ware, power saving device connect in parallel original start -up cashier's office in a shop, the input through start chain ware, the circuit breaker is connected to the power, the output is connected to the fan breaker protector, is connected to the fan through the breaker protector. In this way, the utility model discloses can fundamentally eliminate fan class equipment because lectotype or the big horse dolly of variation in load ubiquitous'' the power wasting phenomenon, make the fan move at best work state all the time to save a large amount of electric energy. 本实用新型提供种智能风机节电装置，包括：启动柜、节电装置、PID控制器和启动连锁器；所述节电装置并联在原有启动柜上，输入端通过启动连锁器、断路器连接至电源，输出端连接至风机断路保护器，通过断路保护器连接至风机。通过上述方式，本实用新型能够从根本上消除风机类设备由于选型或负荷变化普遍存在的"大马拉小车"的动力浪费现象，使风机始终运行在最佳工作状态，从而节省大量的电能。
