Causes of high-energy pump motor is running normally direct start or Y / D start, fan energy, starting current equal to 4-7 times the rated current, which requires not only high network capacity, Tengzhou fan energy, and when you start caused by equipment and the electricity grid will severe impact, affecting life. After using an inverter device using the frequency of the current soft-start function will start from scratch, do not exceed the maximum rated current, Zibo fan energy, reducing the impact on power and power capacity requirements, to extend the use of the equipment life. Frequency of energy-saving technologies, Q- reactive power, COSФ- power factor, Yantai fan energy, known COSФ the greater the greater the active power P, Common pump motor power factor between 0.6 to 0.7, using frequency control devices later, due to the inverter internal filter capacitor, COSФ≈1, thereby reducing the reactive power loss, increasing the active grid. Chen Ju Energy saving soft start (Figure), Yantai fan energy, fan energy provided by the Shandong morning Poly Energy Technology Services Co., Ltd.
