Product features

1. Realize the perfect combination of measurement and control technology and synchronous switch, contro the motion speed of switching switch, eliminate the bounce, improve the life, track and correct the closing phase Angle, and realize the switching life of millions of times. Compared with the existing similar intelligent power capacitors, it has many advantages such as high reliability, low fault, low power consumption and long life.
2. Closing without inrush current, it can realize zero-crossing input of capacitor voltage and zero-crossing excision of current and svnchronous switching can compietelv avoid over-vo tage of switch. no over-votage breakdown. no arc tension and relignition
3. Compensation in the most appropriate way, complete control functions, with high-end power analyzer functions, complete functions, good performance, but also can be configured with a variety of peripherals to meet different customer needs The measurement and protection function of the product is complete, with special protection of temperature inside the control room, harmonic content of the power grid, broken phase, three-phase unbalance, etc
4. The product can be used by multiple building blocks, and the host machine will be automatically generated when used, while the rest are slave machines, constituting the reactive automatic control system. The automatic exit of individual failures from the machine will not affect the work of other machines. Automatic exit of host failure. new host, the composition of new svstem work, high degree of inteigence. The monomer capacitor disnlavs the product working condition and the electrical circuit condition, the man-machine dialogue is simple and intuitive

Operation principle of each component

1. MCUintelligent measurement and controlpart
All electronic components in the intelligent measurement and control module adopt wide temperature type and industrial grade which can adapt to the harsh environment with arge temperature change and serious electromagnetic interference, and can work reliably without interruption for a long time, with high inteligence degree and stable control performance.
2. Zero-crossing switch synchronization technology based on mechanical contact
The company summarizes the characteristics and disadvantages of mechanical contactless thyristors, contactless thyristors and composite switches. Combined with vears of development and practica operation experience the companv independentl develops a new generation and USES microelectronic software and hardware technology to effectively control mechanica alectromagnetic relav contacts, The svnchronous switch technology of ow voltage power capacitor based on mechanica contact i realized. When the ac current at the two ends of the contact is zero. it is closed: when the contact is closed. itis disconnected when the AC voltage at the two ends is zero. Avoid the impact of the inrush current on the system voltage when the capacitor is put in Reduce equipment loss and increase capacitor service life.
3. Low voltage power capacitors
The low-voltage power capacitor in the product adopts self-healing low-voltage shunt compensation capacitor, and progresive thickening zinc-aluminum metallized polypropylene film is used as dielectric, with high stability and reliability. Among capacitors of the same brand, the larger a single capacitor is, the longer and thicker its core components are. The length of the element leads to the increase of resistance loss, the thickness of the element is large, the conductive layer area of the end surface is large, and the temperature difference between the inside and outside of the element increases. which makes the conductive laver more likely to be separated from the plate. Therefore, the use of single-closed large-capacity capacitor is not as reliable as the use of sma -capacity capacitor in paralel. and the switching series of the capacitor can be eectively increased. At the same time. them temperature sensor is built in the capacitor to reflect the intermal heating degree of the capacitor in the case of over-voltage, over-harmonic, leakage flow and high ambient temperature, so as to realize over-temperature protection.
