Abstract
The present invention relates to an intelligent switch capacitor, which comprises a shell. The shell is provided with a capacitor core internally. A temperature sensor is arranged on the capacitor core. A top end of the capacitor core is connected to an intelligent switch wiring board. The intelligent switch wiring board is connected to a single chip computer, a capacity-switch, a temperature measurement module, a current measurement module and a current harmonic component measurement module, wherein the capacitor switch is connected to the capacitor core in an inner triangle way. Beneficial effects of the present invention are: 1. A switch and a power capacitor are integrated into a whole, which can implement quick capacity-switching and cutting of the switch; 2. The capacitor has an electronic thermal protection function; 3. Possibilities of capacitor damages and power grid accidents caused by resonance of a PFC capacitor in a power grid system are eliminated completely; 4. A power capacitor loss is reduced.
