Multiply Auto-switching Reactive Power Compensation Device

Multiply Auto-switching Reactive Power Compensation Device
General
Multiply auto-switching reactive power compensation device is based on a conventional high-voltage shunt capacitor devices, and add a dedicated vacuum capacitor switching and automatic switching control circuit breaker in order to achieve the reactive power groups of  capacitor (2-5 group ) auto-switching, achieved the purpose of load capacity-adjustable capacity.
The device generally is connected by the capacitor switch outlet cabinet through cable.
Application
   The device is mainly used for power frequency system l0kV (6kV), through auto adjustment of the transformer on-load tap and the automatically switching of capacitor banks on l0kV (6kV) bus to achieve integrated control of the substation voltage and reactive power. Improve the system power factor, reduce transformer and line loss, improve the quality of power supply voltage.

The device is mainly designed for corporate users, and can be widely used in chemical, petroleum, metallurgy, coal system, the on-site guidance for product installation and commissioning, taking into account the harmonic problem of business users , we can design reactors rate of 4.5 series reactance or more to make business users get a certain control of Harmonics.
Second, the device can be used for large-scale rural substation, considering the characteristics of rural substation, load and seasonal variation of diurnal variation to achieve the maximum reactive power compensation system.
Third, the device can be used for urban network unattended substation, with "four remotes". Fourth, the device can be used to transform capacitor devices in the old substation to improve the level of substation automation and operational level.
Main features
Special vacuum switch is used which passed the capacitor capacitive switching back to back test, impact resistance, suitable for frequent switching.
Automatic compensation is divided into 2-5 road switching, high precision compensation, the impact is small, can maximize the effect of reactive power compensation.
Controller uses intell6 bit microcontroller, a large-screen character display menu with a friendly interface, real time display of operating parameters and fault information; with RS-485 communication interface, to achieve four remote functions with the substation automation interface, to achieve place, three back-plane and scheduling control and management.
4. Controller with "nine domain areas" control theory, automatic identification of substation transformers and capacitors of various operation modes, to prevent switching shock.
5. Each Way capacitor with over-current protection and internal fault protection, timely and effective fault isolation capacitors, and with voice alarm capabilities, to protect the overall safety and reliability.
