The invention discloses a combined intelligent
capacitor and relates to the technical field of capacitors. The combined intelligent
capacitor comprises a shell, a wiring terminal, a separating compensation
capacitor zero-phase output end and a three-phase capacitor output end, wherein the three-phase capacitor output end is arranged at one side of the top end of the shell and the wiring terminal and the separating compensation capacitor zero-phase output end is arranged at the other side of the top end of the shell; a compound switch is arranged in the shell; three-phase input ends L1, L2 and L3 of the compound switch are connected to a
power grid and three-phase output ends C1, C2 and C3 are connected to a capacitor or an electric reactor; a co-compensation switch is only connected to a separating compensation switch K1 to control three-phase output; the separating compensation switch K1 controls output of the C1, K2 controls the output of the C2 and K3 controls the output of the C3; V is connected to an
anode at the public end of a
control signal; and N is a
power grid null line input end. The combined intelligent capacitor has simple overall structure and simple wiring, a problem of
hybrid compensation installation space is solved, and meanwhile, the problems of narrow distance between parallel electric appliance groups and easiness in heating and damage are solved, the speed of
discharge can be accelerated, and the conditions are created for quick switching of the capacitor.
