KD-H dry environment-friendly capacitor adopts advanced German technology and is manufactured in an environment with a hundred level purification level. The element is heated under 10-3 Bar vacuum condition and the protective gas is injected at the same time. In this way, air and moisture can be discharged from the capacitor, thus avoiding electrode oxidation and partial discharge. Through this complex process and strict factory inspection and quality evaluation, it is ensured that the capacitor has excellent stability and long service life. It can be divided into single-phase and three-phase according to different occasions.

MOKN series capacitors imported from Germany are very popular in the Chinese market because of their unique technology. Nitrogen (N2) filling, special SINECUT slotting technology and unique metal processing technology, as well as the most reasonable inner core position, are used in the production process of capacitors to ensure that the capacitance of equipment remains unchanged under the impact of large AC high-voltage negative pressure. This unique feature of MOKN series products makes it particularly suitable for applications in controlling equivalent DC current and surge.

Low voltage intelligent capacitor
KD-Z series intelligent low-voltage power capacitor is a new generation of reactive power compensation equipment for 0.4KV low-voltage power grid, which can save energy efficiently, reduce line loss, and improve power factor and power quality. It consists of intelligent measurement and control unit, synchronous switch circuit, line protection unit and low-voltage power capacitor. It replaces the conventional automatic reactive power compensation device composed of intelligent controller, fuse, composite switch or mechanical contactor, thermal relay, low-voltage power capacitor, indicator light and other loose parts connected by wires in the cabinet and on the cabinet surface It has changed the bulky and cumbersome structure mode of the traditional reactive power compensation device, so that the new generation of low-voltage reactive power compensation device has the characteristics of better compensation effect, smaller volume, lower power consumption, cheaper price, more cost saving, more flexible use, more convenient maintenance, longer service life, and higher reliability, which adapt to the higher requirements of modern power grid for reactive power compensation.

Low voltage thyristor switching switch
The principle of KS/TSC silicon controlled switch (thyristor) is to ensure that the capacitor bank is put into operation near the voltage zero zone by detecting and controlling the zero crossing of voltage and current, so as to avoid the generation of closing inrush current, and the disconnection is completed when the current is zero crossing, so as to avoid the occurrence of transient over-voltage, which meets the requirements of zero crossing switching of capacitors in terms of function. In addition, there is no limit on the trigger times of silicon controlled rectifier, It can realize quasi dynamic compensation (the response time is in the millisecond level), so it is suitable for the frequent switching of capacitors, and is very suitable for the frequently changing load situation. Compared with the AC contactor, it has a qualitative leap. The advantage of SCR switch is that it can realize zero crossing switching, quick action and quick response, and is mostly used in the occasion of dynamic compensation.
