システムが必要である。Conventionally, a gas-insulated electric device has insulation performance,
Pure SF 6 gas, which is highly isolated, has been used as an insulating gas. However, in order to prevent global warming, it is required to reduce the amount of SF 6 gas used. As a countermeasure, a mixed gas of a gas having a low global warming potential and SF 6 is considered. In FIG.
An example of the insulating properties of a mixed gas of F 6 and N 2 is shown. In a place where the mixing ratio of SF 6 is low, even a slight increase in SF 6 sharply increases the dielectric strength. When the mixing ratio of SF 6 is 20% or more, the increase in the dielectric strength shows a tendency to be saturated. By several% to 20% mixing ratio of SF 6, it can significantly reduce the amount still and will be able to ensure the dielectric strength. When applying this range, it is necessary to consider that the dielectric strength greatly changes depending on the mixing ratio. Therefore, it is necessary to compensate the concentration of SF 6 at the time of initial filling within a specified range. For example, when a mixed gas of 10% SF 6 and N 2 is applied to the insulating gas, it is necessary to reduce the dielectric strength within 10% in order to secure the insulation reliability of the device. Therefore, the concentration of SF 6 must be kept within ± 20%. For this reason, when a mixed gas is applied to the insulating gas of the gas insulated electric device, a system for compensating the gas concentration of SF 6 is required.
