HYTBBD series low voltage dynamic reactive power compensation device

Short Description:

In systems with large load changes, the amount of compensation required for reactive power compensation is also variable, and traditional fixed reactive power compensation devices can no longer meet the compensation needs of such systems; HYTBBD low-voltage dynamic reactive power compensation devices are specially designed for such systems System design, the device can automatically track and compensate in real time according to load changes, so that the power factor of the system can always be kept at the best point. At the same time, it adopts a modular series, which can be combined freely. The assembly and maintenance are extremely convenient and can be expanded at will, cost-effective very high.

Application field

HYTBBD low-voltage dynamic reactive power compensation device is suitable for working conditions with rapid load changes in metallurgy, machinery, mining, building materials, petroleum, chemical, municipal and other industries.

working principle

HYTBBD low-voltage dynamic reactive power compensation device adopts advanced control algorithm to detect and calculate the compensation amount required by the system in real time, control the switching of each compensation branch, and realize accurate reactive power compensation. The switching switch can choose a contactor or a thyristor non-contact switch according to the characteristics of the load change. The contactor adopts a special switching capacitor contactor, and the contactor is equipped with a surge current suppression device, which can effectively reduce the impact of the closing surge current on the capacitor bank Reduce the operating overvoltage; and the thyristor non-contact switch adopts the advanced technology of equal pressure input and zero-crossing cut-off, which can effectively suppress switching surges, improve system reliability, and prolong the service life of capacitors.
