    • PROBLEM TO BE SOLVED: To provide an environment harmonious-type gas-insulated apparatus for electric power capable of removing CO gases generated by reduction of a COgas in a gas-insulated apparatus for electric power using the COgas as an insulation medium and allowing safe maintenance and inspection.SOLUTION: The gas-insulated apparatus for electric power of an embodiment is configured in such a way that a carbon dioxide gas or a mixed gas containing the carbon dioxide gas is filled, as an arc-extinguishing gas, in a hermetically sealed container, and a pair of contacts are disposed inside the hermetically sealed container. At electricity conduction time, both are maintained in a contact state to establish electricity conduction, and at electricity cutoff time, the contacts are separated to generate an arc discharge in the insulation gas, and a current is cut off by extinguishing the arc discharge. A metal oxide is disposed at a place in the hermetically sealed container contacted by a heat flux arising from the arc discharge.
    • 要解决的问题:提供一种用于电力的环境协调式气体绝缘设备,其能够使用CO气体作为绝缘介质,去除用于电力的气体绝缘设备中的CO气体还原产生的CO气体,并且允许安全维护 检查。实施方式的电力用气体绝缘装置构成为将二氧化碳气体或含有二氧化碳气体的混合气体作为灭弧气体填充在气密密封 容器和一对触点设置在密封容器内。 在导电时,两者保持接触状态以建立导电,并且在断电时间,触点被分离以在绝缘气体中产生电弧放电,并且通过熄灭电弧放电来切断电流。 金属氧化物设置在与由电弧放电产生的热通量接触的密封容器中的位置处。
