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...

Embodiment Construction

[0010] see Figure 1-3 , the combined smart capacitor is realized through the following technical solutions: it includes a shell 1, a terminal 2, a sub-compensation capacitor zero-phase output end 3, and a three-phase capacitor output end 4 manufactured by a special mold, and the shell 1 The top side is provided with a three-phase capacitor output terminal 4, and the other end is provided with a binding post 2 and a zero-phase output terminal 3 of the sub-compensation capacitor. A composite switch is provided inside the housing 1, and the three-phase input terminals L1, L2, L3 is connected to the power grid, and C1, C2, and C3 at the three-phase output end are connected to capacitors or reactors. The common compensation switch is only connected to the distribution switch K1 to control the three-phase output. The distribution switch K1 controls the output of C1, K2 controls the output of C2, and K3 controls C3. Output, V is connected to the positive pole of the common terminal ...
