Overview Load Phase LVP series is the use of pulse width modulation AC - AC conversion technology and microcomputer automatic control technology and the development of a high-tech product development, belongs to the State Ministry of Science and Innovation key support areas. The product is designed for medium-sized wound rotor induction motor dedicated reactive power compensation device in place, its salient features are: winding motor can be widely used in a variety of load conditions, variable load more than twice the load mutation conditions rated amount of power factor compensation, the full realization of medium-sized wound rotor induction motor energy consumption, highlighting the traditional reactive power compensation device can not match advantage, it is in series with the motor rotor circuit, by varying the phase relationship between the rotor and the rotor voltage, current, thereby changing the corresponding relationship between the motor stator current and voltage, to improve their motor power factor and efficiency and overload, reduce the motor stator current, lower motor own loss purposes. In the industrial and mining enterprises, power grid reactive power consumption, mainly from the three-phase AC induction motor, therefore asynchronous motor reactive power compensation is the main way the mining industry for energy efficiency. At present, domestic and medium-sized wound reactive power compensation, there are two main ways: one is the motor stator side parallel capacitor; the other is the motor rotor circuit Phase apparatus series; the two methods were used in the constant compensation load state, such as: ball mill can achieve better compensation, but in varying load conditions, due to the varying load fluctuation, and have frequent mutation of characteristics, and presents a batch process, the capacitor and the existing static phase Winding motor control can not meet the changing load conditions for reactive power compensation requirements. In view of this, the company independently developed KP series universal electronic soft phase generator, completely solve the winding motor varying load conditions of the reactive power compensation issues. Load Phase LVP series uses an advanced AC - AC inverter technology and computer control technology, high sensitivity electronic measurement technology and phase-locked loop phase lock technology that automatically track changes in motor load operating conditions, timely detection of anti-motor potential, based on the potential change rate of the anti-electric motor the size of the motor load is determined using phase-locked loop phase lock technology to track locking timely compensation phase, automatically adjusts the rotor circuit superimposed on the magnitude of the additional force, automatically adjust the parameters, so that the motor Reactive power compensation always maintain the best compensation effect, significant energy saving. The motor is running smoothly and efficiently, greatly reducing the temperature of the motor, extending the life of the motor. 75 ~ 10000kW phase generator can be widely applied to steel, wood, sugar, rubber industry, metallurgy, mining, cement, chemicals, paper, pharmaceutical and other industries and medium-sized wound rotor induction motor Variable load or constant load state Large and Medium Asynchronous Motor spot compensation. Such as: ball mill, rolling mills, presses, fans, pumps, crushers, compressors. Main features.
