FILTER COMPENSATING PLANT Russian patent published in 2019 - IPC H02J3/01 

FIELD: electrical engineering.

SUBSTANCE: filter compensating apparatus comprising a compensated network, a filter compensating device made in the form of a magnetic conductor of U-shaped rods, a capacitor made in the form of series-according to two-wind windings from foil wound on rods of the magnetic core in the form of two separate parts, in each part the foil windings inputs are isolated from each other by the dielectric films, is characterized by that it is equipped with two additional filtering-compensating devices identical to the filtering compensating device, in each filter compensating device, the foil cross-section along the length of each of the series-according to the winded parts of the windings is variable, and section of foil part of windings half of length, which is adjacent to compensated network, is three-seven times larger than cross sections of remaining parts of windings, in parallel to the compensated network, all filter compensating devices are connected with adjustment performed for each of network voltage harmonics by changing length of non-magnetic gap of magnetic conductor.

EFFECT: reduced level of irreversible losses of electric energy, reduced weight and dimensions, increased power factor and reduced coefficients of harmonic components of electric circuit voltage.
