Product introduction
H series intelligent power capacitor compensation device is a new generation of reactive power compensation equipment, which is 0.4, 50hz low voltage distribution high efficiency energy saving, reducing line loss, improving power factor and power quality. it consists of intelligent measurement and controlunit, thyristor compound switch circuit, line protection unit, two (△typ e) or one (y-type) l ow-voltage power capacitor. Replace the conventional automatic reactive power compensation device composedof fuse, composite switch or mechanical contactor, thermal relay, low voltage power capacitor, indicator light and sc on in the cabinet and the cabinet surface is connected by the wire. The new generation of low-voltage reactive power compensation equipment has the ch aracteristics of better compensation effet, smaller volume, lower power consumption, cheaper price, more cost saving, more flexible use, longer service life, longer service life, longer service life, and higher reliability.
H series intelligent power capacitor compensation device uses a customized segment LCD, which can display three-phase bu s voltage , three-phase bus current, th ree-phase power factor, frequ ency, switching state, active power, reactive power, total harmonic distortion, and the temp erature of capacitor.
H series intelligent power capacitor compensation device through the internal thyristor compound switch circuit, automatically find the best input(cut)point, realize the arc-free; G uaranteed zero- switching. no inrush current, no si ntering . micro-energy consumption , no h armonic , and with anti -interference, lightning protection and power shortage phase, no- load trip protection functi on, especially suitable for reactive power compensation switching capacitor, do not need to install the radiator.
Characteristics
The capacitor discharge circuit developed by our company independently, so that the capacitor can be released in 1-2s; reliable protection of the capacitor and the life of the composite switch. ( this technology can be more convenient for dynamic compensation device, the same industry compound switch ( no discharge circuit ) after the capacitor is cut, if the capacitor is not finished, it will cause silicon scr breakdown or capacitance damage ).
This product uses the advanced software zero-crossing detection technology, can accurately find out the zero, at the same time in the detection of harmonic does not issue the input command, the peers mostly adopt the hardware zero -crossing mode ( such as zero-crossing optical coupler, this method can not accurately capture the zero point due to the difference of the device ).
Phase protection : when the phase a, b and c phase in the power grid , the corresponding intelligent capacitor bank is no longer input, and the corresponding intelligent capacitor has been put into operation to protec the equipment.
