The utility model discloses a reactive combination control device used for 10 kV circuit voltage, comprising a breaker, an arrester, a reactive compensator, a feeder voltage regulator and an isolation switch. The inner of the reactive compensator is provided with a control device and a metering device used for metering the electric energy to the high-voltage side. The control device checks the electric voltage, the current and the reactive power of the circuit according to the predetermined value, and the control instruction is sent to adjust the electric voltage and the reactive load of the circuit automatically. All the above components are arranged on an electrical pole by a conducting wire, an insulator, a mounting frame and a pull force steel cable. The can proceed with switching operation, over-current protection, checking and metering, line voltage regulation and circuit reactive compensation to a specific circuit, the power factor is improved, and the line loss is reduced. The reactive combination control device is arranged on the proper position of the 10 kV circuit for protecting the circuit, the voltage quality is improved, and the reactive combination control device is especially suitable for the net allocated circuit with large line voltage fluctuation and low power factor.
