摘要： An object is to provide gas insulated switchgear that is able to inhibit heat generation of a pressure container. Electrically-conductive members that are non-magnetic and have higher electric conductivity than that of the material of which the pressure container is made, are provided on the inside and on the outside of the pressure container, while being positioned along a main bus and being attached via a flange of the pressure container. Thus, eddy current that occurs when an electric current flows through the main bus are caused to flow through the electrically-conductive members having higher electric conductivity than that of the pressure container. Also, a current return path for the eddy current is formed by a flow path including the electrically-conductive members. Consequently, it is possible to reduce the eddy current flowing on the pressure container and to inhibit an increase in the temperature of the pressure container.

摘要： A DC circuit breaker includes: a mechanical switch (2) provided on an electrical path (1) through which a direct current flows; and a semiconductor switch (20) connected in parallel with the mechanical switch (2). The mechanical switch (2) includes a gas disconnector (3) and a vacuum circuit breaker (4) connected in series. Normally, the direct current flows through the mechanical switch (2). When interrupting the direct current, the vacuum circuit breaker (4) is made nonconductive to allow the direct current to be commutated to the semiconductor switch (20), and subsequently the gas disconnector (3) and the semiconductor switch (20) are made nonconductive. A vacuum circuit breaker (4) having a low withstand voltage can be used.
