Jinneng Power Technology (Hubei) Co., Ltd.

Anti-harmonic intelligent power capacitor used in 0.4KV power grid. It consists of CPU measurement and control module, capacitor switching composite switch, capacitor protection module, series reactor and low-voltage self-healing power capacitor to form an independent and complete intelligent compensation unit The low voltage reactive power compensation device composed of intelligent capacitors has the characteristics of flexible compensation mode (co-compensation and sub-compensation can be any combi nation), easy installation and maintenance, strong protection function, small device size, good compensation effect, low power consumption, high reliability, etc., to meet the requirements of users for reactive power compensation, and in deed to improve power factor, improve power quality, energy saving and loss reduction.

Realize the perfect combi nation of measurement and control tech no logy and synchronous switch, no thyristor, high voltage resistance between contacts, synchronous switching, automatic tracking and calibration of closing phase, switch to achieve millions of switching life. Compared with the existing smart capacitors of the same type, it has many advantages such as high reliability, low fault and long life.

Product measurement protection function is complete, with capacitor internal temperature, lack of phase, over voltage, under voltage and other protection functions.

Products can be used in multiple building blocks, different capacities flexible collocation,when multiple sets are used, the host is automatically generated, the rest are slave machines, and individual slave machines exit without affecting the work of other machines, high degree of intelligent.

Note: Products with a reactance of 7% are mainly used for occasions with higher harmonic content of 5times or more; Products with a reactance of 14% are mainly used for occasions with higher harmonic content of 3or more times;
