COOLING SYSTEM FOR A DRY-TYPE AIR-CORE REACTOR
First Claim
1. A cooling system for a dry air-core reactor, the reactor comprising a winding around the air-core, the air core comprisingfirst open spaces to let air flow through the winding in parallel with an axis of symmetry of the reactor andsecond open spaces crossing the first open space to let air flow through the winding angular to the axis of symmetry, the cooling system comprising:
- a ventilation unit producing a forced-air flow, where a first part of the forced-air flow enters one of the first or second open spaces,at least one guiding element which is arranged with respect to a crossing of the first and the second open spaces in such a way that the first part of the forced-air flow leaves and a second part of the forced-air flow enters the one of the first or second open spaces, anda shielding element is arranged at another crossing of the first and the second open spaces so that substantially no air can leave or enter the one of the first or second open spaces.

Abstract
An air-core reactor with natural-air cooling of a winding includes first open spaces to let air flow through the winding in parallel with an axis of symmetry of the reactor and second open spaces crossing the first open spaces to let air flow through the winding angular to the axis of symmetry. A ventilation unit to produce a forced-air flow is arranged in such a way to the air-core reactor that a first part of the forced-air flow enters one of the first or second open spaces and at least one guiding element is arranged with respect to the crossing of the first and the second open spaces in such a way that the first part of the forced-air flow leaves and a second part of the forced-air flow enters the one of the first or second open spaces. A shielding element is arranged at another crossing of the first and the second open spaces so that substantially no air can leave or enter the one of the first or second open spaces.

10. A method to convert an air-core reactor with natural-air cooling into an air-core reactor with forced-air cooling, wherein the air-core reactor comprises
a winding around the air core, first open spaces to let air flow through the winding in parallel with an axis of symmetry of the reactor and second open spaces crossing the first open space to let air flow through the winding angular to the axis of symmetry, the method comprising: -
arranging a ventilation unit to produce a forced-air flow towards the air-core reactor so that a first part of the forced-air flow enters one of the first or second open spaces, arranging at least one guiding element with respect to a crossing of the first and the second open spaces in such a way that the first part of the forced-air flow leaves and a second part of the forced-air flow enters the one of the first or second open spaces, and arranging a shielding element at another crossing of the first and the second open spaces so that substantially no air can leave or enter the one of the first or second open spaces.
