Abstract
Abstract Device for supplying power from a three-phase network to an ozonizer comprising at least two discharge elements (3, 4) having a capacitive character, and comprising two single-phase step-up transformers (1, 2) having air gaps connected in a SCOTT circuit and connected between the three-phase network and said discharge elements (3, 4). The device further comprises a three-phase transformer (8) whose secondary windings (5, 6, 7) are connected between said single-phase transformers (1, 2) and the three-phase network and whose primary windings (9, 10, 11) are star-connected and connected to the three-phase network through a dimmer (12).

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
108 words
A device for supplying from a three-phase network an ozonizer comprising at least two discharge elements having a capacitive character, said device comprising two single-phase step-up transformers having secondary windings, primary windings and air gaps connected in a SCOTT circuit and connected between the three-phase network and said discharge elements, said device further comprising a three-phase transformer having primary windings and secondary windings, the secondary windings of the three-phase transformer being connected between said single phase transformers and the three-phase network and the primary windings of the three-phase transformer being star-connected and a dimmer connects each of the primary windings of the three-phase transformer to the three-phase network.
Claim 2
Independent Claim
108 words
A device for supplying from a three-phase network an ozonizer comprising at least two discharge elements having a capacitive character, said device comprising two single-phase step-up transformers having secondary windings, primary windings and air gaps connected in a SCOTT circuit and connected between the three-phase network and said discharge elements, said device further comprising a three-phase transformer having primary windings and secondary windings, the secondary windings of the three-phase transformer being connected between said single phase transformers and the three-phase network and the primary windings of the three-phase transformer being star-connected and a dimmer connects each of the primary windings of the three-phase transformer to the three-phase network.
Claim 3
Dependent Claim
19 words
