Abstract
A gas insulation apparatus has a sealed container, an insulation gas, a high-voltage portion, and a removal material. The insulation gas has CO2 and O2 filling the sealed container as main components. The high-voltage portion is stored in the sealed container. The removal material reduces concentrations of HF, CO, and O3 in the insulation gas.
Claims8
A gas insulation apparatus comprising:
- a sealed container;
- an insulation gas that has CO2 and O2 filling the sealed container as main components;
- a high-voltage portion that is stored in the sealed container;
- and
- a removal material that reduces concentrations of HF, CO, and O3 in the insulation gas,
- wherein:
- the removal material is a synthetic zeolite in which a mole ratio of silica/alumina is 5 or higher,
- the sealed container includes an exhaust cylinder through which the insulation gas is able to flow after being sprayed to arc discharge generated inside the sealed container, and
- the removal material is disposed at an end of the exhaust cylinder and disposed coaxially with the exhaust cylinder.
