low voltage compensator for power distribution

  Product Description The details show   Low voltage GBD serial dynamic reactive power compensation devices are developed from the Company's original low voltage TSC serial dynamic reactive power compensation device. Operating environment/h2> u  Ambient temperature: -25℃ ~+40℃ u  Maximum daily temperature difference: 25℃ u  Altitude: ≤2000m, special design available over 2,000m u  Environment relative humidity: annual average value≤90% u  Seismic intensity: 8 Richter scale u  Pollution level: III u  Installation method: indoor installation   Power Supply Condition   u  System Standard Voltage: 400V, 690 (660)V   u  Maximum working voltage: 440V, 759V   u  Rated frequency: 50Hz, 60Hz   u  Phase number: 3 Technical indicators u  Rated capacity: It is possible to be configured in accordance with users' demands with the single cabinet rated compensation capacity ≤600kvar. In case of an exceeding of this compensation capacity, it shall be advised to adopt the configuration of combination of the main cabinet with auxiliary cabinet. u  Grouping condition: grouping arbitrarily based on users’ actual requirements u  Dynamic overload capacity: Long-time operation under 1.30 In (rated current). Over-current is the interaction result of harmonics and 1.1 Un (rated voltage). Long-time operation under 1.10 Un. Longest operation of 30min under 1.15 Un every 24 hours. u  Power factor: over 0.95 (set between 0.8 and 1) u  Controlled pathway: 24 pathways u  Respond time: ≤20ms u  Reactance rate: 5%, 6%, 7%, 12%, 13% u  Switching delay: set according to users’ requirements u  Protection grade: IP30 (can be designed according to users’ requirements) u  AC sampling voltage: the voltage of System power supply; AC sampling current: 0~5A Technical features u  Instead of manual intervention, the achievement of automatic fling-cut and adjustment in accordance with the grid system reactive power and voltage control requirement makes it possible to compensate the reactive power automatically as well as to increase the system power factor, by which, in case of a sufficient compensation capacity, it will be ensured to retain the system power factor equal to or above 0.95. u  There is an achievement of non-contact electronic switch developed with the technology of thruster with two-way anti-parallel connection, which makes it possible to extend the service life of switches to a great extent. u  There are achievements of zero-triggering fling-cut, shock-free, flow-free and over-voltage, and non-introducing of transient state or harmonics. u  The fast switching makes it possible to complete the fling-cut od capacitor within 20ms. u  There are options of three-phase common compensation, separate phase compensation and mixed compensation. u  With the superior "e-dog software" circuit and fault-tolerant technology, it is made possible to automatically discover the runtime error and thoroughly eliminate the "crash" phenomenon. u  The unique “hardware circuit fault protection circuit” can ensure it will not cause output false operation. u  The service life of the capacitor is extended. u  Improve static and dynamic stability of power system. u  There is a decrease of the imbalanced voltage and current, which is also an improvement of the voltage quality and stabilization of system voltage as well as restraining of voltage flicker. u  It gives a decrease of grid loss, efficient energy conservation, an improvement of the efficiency of electrical equipment, and an increase of transformer load. u  Complete protection measures (overvoltage, undervoltage, phase loss, over-current and short circuit etc ). u  The series inductance may prevent from harmonic amplifying and absorb part of the harmonic current. u  It is provided with full digital control, real-time detection and calculation of the amount of reactive power. u  There is a dynamic display for quality parameters of system power factor, voltage, current, frequency, active and reactive power and harmonic. u  There are functions of on-line parameter setting and parameters memory. u  The number of ways of fling-cut shall be displayed for indicating the conditions of work. u  Both manual and automatic fling-cuts are available with an easy and flexible operation. u  The RS485 and CAN communication interfaces are able to be connected with computers or other equipments. u  The function of automatic recovery from power-off is available.     specifications model  and working principle are as follows :   Company Information             Harbin Codm Electric Co., Ltd.
