The utility model relates to an anti-harmonic capacitor, and specifically relates to an intelligent integrated power capacitor. The intelligent integrated power capacitor comprises a cabinet, an intelligent measurement and control device, a switching switch control unit, and four capacitors, wherein the four capacitors are arranged on the bottom of the cabinet; a separator is arranged in the middle of the cabinet; the intelligent measurement and control device and the switching switch control unit are fixed on the separator; the intelligent controller is connected with the switching switch control unit; and the switching switch control unit is connected with the capacitors. According o the utility mode, the structure of the intelligent integrated power capacitor is simplified into several modules, so that the power capacitor is simple in structure and small in size, and the wiring is simplified; and the power capacitor is provided with a temperature sensor which can indicate the heating inside the capacitor caused by over current, over harmonic, over electric leakage and over environment temperature, thereby achieving over-temperature protection. When the temperature exceeds a preset temperature, the switching switch control unit automatically disconnects the capacitors, and stops operation, thereby protecting the equipment.
