Abstract
Provided is an on-line ice-melting apparatus. The apparatus is configured for melting the ice on a three-phase line. The apparatus includes an adjustable reactor, a grounding transformer, a controller, and an auxiliary circuit. The grounding transformer, the adjustable reactor, the auxiliary circuit, and a line of any phase of the three-phase line form a first control loop. The adjustable reactor includes a working winding, a control winding, and a short-circuit winding. The working winding is connected between the grounding transformer and the auxiliary circuit. The controller is electrically connected to the control winding and the short-circuit winding separately.
Claims10
An online ice melting apparatus, applied for melting ice on a three-phase line, comprising an adjustable reactor, a grounding transformer, a controller, and an auxiliary circuit;
- wherein the grounding transformer is electrically connected to the three-phase line and a first terminal of the adjustable reactor separately, the auxiliary circuit is connected between a second terminal of the adjustable reactor and a line of any phase of the three-phase line, and the grounding transformer, the adjustable reactor, the auxiliary circuit, and the line of the any phase of the three-phase line form a first control loop;
- and
- wherein the adjustable reactor comprises a working winding, a control winding, and a short-circuit winding;
- the working winding is connected between the grounding transformer and the auxiliary circuit, the controller is electrically connected to the control winding and the short-circuit winding separately, and the controller is configured for adjusting a reactance value of the control winding and/or a reactance value of the short-circuit winding to adjust a reactance value of the working winding so as to control a current of the first control loop.
