  • Patent number: 11015987
    Abstract: A temperature estimation method estimating a temperature of a heat generating site in an oil-immersed electric appliance immersed in insulating oil, the insulating oil being silicone oil or ester oil. The temperature estimation method includes measuring concentrations of two types of thermal decomposition products in the insulating oil and calculating a temperature of the heat generating site in the oil-immersed electric appliance based on a concentration ratio between the two types of thermal decomposition products and a relational expression between the temperature of the heat generating site and the concentration ratio prepared in advance. When the silicone oil is adopted as the insulating oil, at least one of the two types of thermal decomposition products is straight-chain siloxane, alcohol containing silicon, or benzene. When the ester oil is adopted as the insulating oil, the two types of thermal decomposition products are fatty acids.

  • Publication number: 20210075169
    Abstract: An IC socket incudes a socket body having a housing portion for accommodating an IC package; a contact pin electrically connected to a solder ball of the IC package; an operating member provided movably up and down on the socket body; and a pad which is opened and closed by an up and down movement of the operating member and covers an upper side of the IC package in a closed state. The housing portion is provided with an annular portion surrounding a side periphery of an accommodating area of the IC package, an accommodating space for the electric component is formed when the pad is closed and abuts the annular portion, and the pad is configured to be spaced upwardly from an upper surface of the IC package which is accommodated in the accommodating space when the pad is closed and abuts the annular portion.
