Summary

The ADDZN series intelligent integrated power capacitor compensation device (hereinafter referred to as intelligent capacitor) is composed of power parameter detection technology, reactive power compensation control technology, display technology, power capacitor switching control technology, intelligent capacitor networking technology, fault monitoring and protection technology, as well as power capacitors and circuit breakers. A single intelligent capacitor can form a complete compensation system. No need to set any control parameters to start up and use normally, simple and flexible to use. Mainly used for static reactive power compensation in 0.4KV power systems, improving the power factor of the power grid, reducing power grid losses, increasing the output capacity of transformers, improving voltage output quality, and avoiding penalties for power regulation fees.

Functional characteristics

☆ Adopting low-power design, more energy-efficient than traditional compensation structures

☆ Quickly complete automatic networking and shorten the waiting time for on-site installation and debugging

☆ Automatically identify the same name end of the current signal to prevent abnormal operation of the current line from being reversed

☆ Zero crossing switching technology, with no surge current input and no arc pulling during cutting

☆ The average power factor within the delay time is used as a reference physical quantity to avoid frequent switching

☆ Both self-control and controlled modes are optional. In self-control mode, automatic optimization compensation can be achieved without the need for an external controller

☆ Multiple protection functions such as overvoltage, undervoltage, undercurrent, phase loss, harmonics, and over temperature are provided to improve the stability of the system
