Title:
INSULATING TRANSFORMER
Document Type and Number:
Japanese Patent JP3665945
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To reduce discharge current and to absorb energy, so that the energy accumulated in a capacitor formed between a low-tension side shield plate on a primary coil of an insulating transformer and a high-tension side shield plate under a secondary coil do not give damages to a load at load-grounding.
SOLUTION: Where a transformer 2 is housed is provided, and the metal case 1 is filled with an insulating oil 6, and the metal case 1 is provided with a low-tension side power supply terminal 3, a high-tension side power tapping bushing 4, and a ground terminal 5. Here, a metal conduit 16 is provided at a central part of the high-tension side power tapping bushing 4. Then a plurality of iron cores 31 are split-allocated around the metal conduit 16 with an insulating plate 32 in between, so as to provide a gap.
