Intelligent harmonic suppression reactive power compensator is an integrated reactive power compensation device used in 0.4KV power grid. It consists of CPU measurement and control module, capacitor switching composite switch, capacitor protect!on module, series reactor and low-voltage self-healing power capacitor to form an in dependent 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 the power factor, improve voltage quality, energy saving and loss reduction.
Realize the perfect combi nation of measurement and control tech no logy and syn chronous 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, overvoltage, undervoltage 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 individuals lave machines exit without affecting the work of other machines. High degree of intelligence.
