TRANSFORMER UNIT FOR HIGH-PRESSURE DEVICE AND POWER SUPPLY DEVICE FOR HIGH-PRESSURE DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a transformer unit for a high-pressure device capable of preventing a decrease in power efficiency of a power transformer due to eddy current loss in a metal component near a core.;SOLUTION: A transformer unit 10 for a high-pressure device comprises a core 12, and a power transformer 11 including a primary winding 13 and a secondary winding 14. The core 12 is annularly formed by a magnetic material, and the primary winding 13 and the secondary winding 14 are wound around the core 12. The power transformer 11 boosts the voltage supplied to the primary winding 13 to a voltage for driving the high-pressure device, and outputs the boosted voltage from the secondary winding 14. The transformer unit 10 comprises a pedestal 51 for fixing the power transformer 11 to a fixed part 30 in a state in which a part of the power transformer 11 is mounted. The pedestal 51 is composed of a non-magnetic material having insulation properties.;SELECTED DRAWING: Figure 3;COPYRIGHT: (C)2018,JPO&INPIT
