Basic functions and performance characteristics of intelligent capacitors

The intelligent capacitor can be used by single or multiple on-line. Instead of the general active reactive power compensation assembly composed of intelligent controller, fuse, composite switch or machine type war fighter, thermal relay, high voltage power capacitor, instigator lamp and so on.

Modular layout

The intelligent capacitor is of modular layout, small size, simple field wiring and convenient protection. The expansion of reactive power compensation system can be realized only by increasing the number of modules.

High quality capacitor

The self-healing high-voltage compensation capacitor is adopted, the temperature sensor is built in the capacitor, and the temperature inside the reaction capacitor is high enough to realize over temperature protection.

Embedded switch module

The intelligent capacitor has built-in switch module. The switching switch module is composed of thyristor, magnetic link Relay, zero crossing trigger conduction circuit and thyristor protection circuit to realize "zero switching" of capacitor and ensure no inrush strike and no operation over-voltage in the switching process. The switch module has fast response speed and can be operated frequently.

Perfect shelter

The intelligent capacitor has the functions of power failure protection, short circuit protection, voltage phase loss protection, capacitor over temperature protection, etc., which can effectively guarantee the quiet of the capacitor and extend the service life of the equipment.

Master of technology control

Control the physical quantity as reactive power, adopt the technology of reactive tide prospect and delay multi-point sampling to ensure the switching without oscillation. In case of heavy load, the reactive power will be fully compensated.

Anti switching oscillation technology

Adopt the strange idea to avoid the site of the compensation or over compensation caused by the controller crash, and avoid the switching oscillation of the capacitor.

Active compensation for reactive power

According to the size of the load reactive power, the intelligent capacitor switches on and off actively, compensates the reactive power statically and improves the power quality. The intelligent capacitor can be used by single or multiple on-line.

Friendly human-computer interface

Display the operation parameters of current, voltage, reactive power and other equipment.

Display switching status, fault status of composite switch module and communication status.

And it is convenient to realize the functions of debugging / event state switching and manual / active control.

The intelligent capacitor integrates intelligent control module, fast switching switch and capacitor shelter. It is envisaged that the layout is exquisite and the equipment can be set flexibly to meet the user's demand for reactive power compensation.
