Abstract

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.

Description

technical field [0001] The invention relates to the technical field of capacitors, in particular to a combined smart capacitor. Background technique [0002] At present, the smart capacitors commonly used are mostly one capacitor unit, and the shell generally has a relatively large reserved space. If the core group is placed unbalanced, long-term accumulation will lead to serious internal energy accumulation, and the explosion-proof mechanism will not start. The risk of breaking down the capacitor core or causing the assembled capacitor to bulge and even cause a fire is increased. In addition, the problems and causes of the traditional low-voltage reactive power compensation system: large volume, poor heat dissipation of the whole cabinet, once the product is formed, it is inconvenient to expand. [0003] Due to the current power grid operation process, it is very easy to have three-phase unbalanced phenomena. For example, if a single AC contactor device with the same input...
