Title:
INSULATION STRUCTURE FOR ELECTRIC VEHICLE
Document Type and Number:
Japanese Patent JP2017118661
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an insulation structure for an electric vehicle that prevents insulation breakdown without being limited by output even at a high altitude.SOLUTION: An insulation structure for an electric vehicle that prevents insulation breakdown of at least a rotary electric machine mounted in an electric vehicle, comprises: a sealed case 3a holding pressure in the rotary electric machine 3; a sealed case 4a holding pressure in an inverter 4; pressure sensors 32A, 32B that detect pressure in the sealed case; an atmospheric pressure sensor 33 that detects atmospheric pressure; pressure adjustment valves 31A, 31B that switch sealing of the sealed case and communication with atmosphere; and a pressure control part 30 that controls a pressure adjustment valve. A pressure control part exerts control such that if pressure in the sealed case is equal to or higher than atmospheric pressure, the pressure adjustment valve is closed, and if pressure in the sealed case is lower than atmospheric pressure, the pressure adjustment value is opened.SELECTED DRAWING: Figure 2
