The column mounted outdoor line reactive power compensation complete set device is suitable for high-voltage distribution lines with rated voltage of 10kV or 6kV, and is used to improve power factor, reduce line losses, and enhance voltage quality. By automatically switching capacitor banks, the reactive power of 10kV/6kV distribution lines is dynamically compensated, improving power factor (up to 0.95 or above), reducing line loss (15%~30%), and stabilizing voltage.
This device consists of a full film high-voltage parallel capacitor, an outdoor type switching capacitor dedicated vacuum contactor (with built-in current transformer), a control power transformer, a zinc oxide lightning arrester, a drop out fuse, a reactive power compensation automatic controller, an outdoor high-voltage current transformer, and installation fittings. Complete configuration, compact structure, and easy installation.
This device can automatically switch parallel capacitors based on the actual needs of the circuit, pre-set by the user, and controlled by a microcomputer to achieve a predetermined range of power factor for the circuit. At the same time, it has protection functions such as short circuit, overcurrent, overvoltage, undervoltage, voltage loss, preventing capacitors from closing with charges, phase loss, and fault lockout self diagnosis. Moreover, various parameters can be changed at any time.
The outdoor high-voltage vacuum AC contactor used in this device is a specialized switch developed by our company for switching high-voltage parallel capacitor banks. It can absolutely guarantee "no bounce when closing" and "no reignition when opening", with an electrical and mechanical lifespan of over 300000 times.
