<p>A gas-insulated switching device (1) uses, as an insulating gas, a mixed gas with a pressure higher than atmospheric pressure including as principal components a nitride gas and a gas with a global warming potential of no more than one. In the gas-insulated switching device (1), the gas pressure in a breaker container (10a) containing a vacuum breaker (10) equals the gas pressure in a line disconnector container (25a), the gas pressure in bus containers (17a, 18a) equals the gas pressure in bus disconnector containers (15a, 16a), and the gas pressure in the bus disconnector containers (15a, 16a) and the gas pressure in the bus containers (17a, 18a) are higher than the gas pressure in the breaker container (10a) and the gas pressure in the line disconnector container (25a).</p> |
