Title:
MAGNETIC LEAKAGE SHIELDING METHOD OF SUPER-LARGE CAPACITY TRANSFORMER
Document Type and Number:
WIPO Patent Application WO/2010/078682
Kind Code:
A1
Abstract:
A magnetic leakage shielding method of a super-large capacity transformer comprises the following steps: a first magnetic shield group (4) is arranged laterally on a tank wall at an upper and a lower ends of the corresponding coils between pole I and pole II and between pole II and pole III, the lateral magnetic shield makes the leakage flux of the pole II balance with each half of the leakage flux of pole I and pole III, and the first magnetic shield group is arranged to keep away from the middle of a high voltage outlet line of the middle pole II; a second magnetic shield group (3) is arranged vertically on the corresponding tank wall outside pole I and pole III, and the second magnetic shield group is used to flow the leakage flux of pole I and pole III which is not balance with that of the pole II.
