Phase generator, LVP Series Load phase advancer

Overview: LVP Series Load Phase is using pulse width modulated AC - AC inverter technology and microcomputer automatic control technology and the development of a high-tech product development, belonging 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 notable features are: Winding motor can be widely used in a variety of load conditions, variable load more than twice the load of mutations nominal amount of power factor compensation conditions, the full realization of medium-sized wound rotor induction motor's energy consumption, highlighting the traditional reactive power compensation device incomparable advantages, it is connected in series with the motor rotor circuit, by varying the phase relationship between the rotor and the rotor voltage, current, and then change the corresponding relationship between the motor stator current and voltage, to improve their motor power factor and efficiency and overload, reduce motor stator current, reduce motor own loss purposes. In the mining industry, the power consumption of reactive power mainly from the three-phase AC induction motor, so the high-power induction motor reactive power compensation is the main way the mining industry energy conservation. Currently, domestic and medium-sized wound reactive power compensation, there are two main ways: one is the motor stator side shunt capacitor; the other is a tandem rotor circuit device into phase; the two methods of compensation are in constant use load conditions, such as: ball mill can achieve better compensation, but in varying load conditions, due to the varying load fluctuation, and have frequent mutations characteristics, and exhibit batch process, capacitors and existing static phase Winding motor control can not meet the varying 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 load conditions varying 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, the timely detection of anti-motor potential, according to the anti-electric motor to determine the rate of change of the potential size of the load of the motor, the use of phase-locked loop phase lock technology timely compensation phase locked tracking, automatic adjustment additional superimposed on the rotor circuit emf amplitude, automatically adjust the parameters, so that the motor Reactive power compensation remains the best compensation effect, energy saving is significant. Smooth and efficient operation of the motor, which greatly reduces 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 load or constant load change state medium-sized wound rotor induction motor in place compensation. Such as: ball mill, rolling mills, presses, fans, pumps, crushers, compressors. Main features: 1, using 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, the timely detection of the back EMF of the motor. 2, variable load conditions to reduce the stator current 10% to 80%, reduce line losses, copper loss of 20% -50%; constant load conditions to reduce the stator current 10% to 20%, reduce line losses, copper loss of 20% -30 %. 3, significant energy saving, into phase allows the motor power factor to 0.95, reactive power saving of more than 80% of its outstanding ordinary into the phase compensation effect can not be compared drafted. 4, with soft Phase function, electrical and mechanical equipment without shock, extending the life of the soft phase generator and electrical and mechanical equipment. 5, the motor temperature significantly reduced, overload and operational efficiency is greatly improved, thus prolonging the life of the motor. 6, automatic tracking changes in the motor operating conditions and automatically adjusts the overlay attached to the rotor circuit emf amplitude, automatically adjust the parameters, so that the reactive power compensation motor always maintain the best compensation effect. 7, the compensation capacitance characteristics than existing Phase compensated, both to improve the power factor of the line, but also improve the power factor of the motor itself. 8, with automatic fault protection function, simple operation, maintenance without affecting production.
