Title:
ON-VEHICLE TRANSFORMER AND OIL FLOW RELAY
Document Type and Number:
WIPO Patent Application WO/2019/220587
Kind Code:
A1
Abstract:
An on-vehicle transformer (100) is provided with a transformer body, a tank (110), an insulating oil (120), a cooler (130), a connection pipe (140), a pump (150), and an oil flow relay (160). The oil flow relay (160) includes a blade member (162), a movable contact element (164), and a fixed contact (166). The movable contact element (164) includes a movable contact (164c), and rotates about a center axis in association with rotation of the blade member (162). The fixed contact (166) is located on the rotating path of the movable contact (164c). The oil flow relay (160) is configured such that the operating flow rate in the oil flow relay (160), which is the flow rate of the insulating oil (120) flowing through the connection pipe (140) at the time of contact between the movable contact (164c) and the fixed contact (166), becomes lower with a decrease in the temperature of the insulating oil (120).
