2025年3月1日 · Recently, we determined that CO 2 gas readily diffuses through porous ceramic thermal insulators, and then measured diffusion rates for several such aluminum silicate and calcium magnesium silicate insulators acting as CO 2 -membranes [15].

In this paper, we describe the fundamental insulation breakdown characteristics of high-pressure CO2 gas at gas pressures of up to 1.0 MPa under simulated practical conditions, including the insulation breakdown characteristics of a high-voltage conductor with an insulating coating and the effect of decomposition products on the creeping insulat...

Abstract: This article reports on an investigation into the surface flashover characteristics of the 252-kV conical insulator in a C4F7N/CO2 mixture, which is used as an alternative to sulphur hexafluoride (SF6). This study was done for a quasi-uniform …

2022年2月28日 · Surface flashover along the insulator/gas interface is a restrictive factor in the design of gas-insulated equipment. Thus, the surface flashover properties is very important. In this paper, the one-minute test with power frequency and surface flashover test are preformed using a 220kV GIL and the electric field is also simulated.

2008年8月8日 · In this paper, we describe the fundamental insulation breakdown characteristics of high-pressure CO 2 gas at gas pressures of up to 1.0 MPa under simulated practical conditions, including the insulation breakdown characteristics of a high-voltage conductor with an insulating coating and the effect of decomposition products on the creeping ...

2006年3月9日 · This paper deals with a suitable insulation gas which has no greenhouse effect as an SF 6 alternative gas. The N 2 /O 2 mixed gas was investigated by changing the ratio of O 2. Moreover, the effect of an insulation coating was investigated and compared with the dielectric strength of SF 6 /N 2 mixed gas.

Insulation for Sustainability A Guide A study by XCO2 for BING Global warmingis the most immediate threat to global sustainability, driven primarily by CO2 emissions. Achieving optimum thermal designof buildings can achieve large cuts in CO 2, with numerous other benefits. But at least half of Europe’s existing buildings are uninsulated ...

According to today’s consideration the most suitable insulating alternatives are nitrogen (N 2), carbon-dioxide (CO 2) and mixtures of both gases. For insulation and switching behavior no acceptable alternatives have been found1.

2005年9月1日 · In this study, HFO‐1336mzz(E) and N2/CO2 mixtures are proposed as SF6 substitutes for their short atmospheric lifetime, low GWP and superior insulation performance.

2024年9月1日 · Here, a method of effective CO 2 diffusion is demonstrated that simultaneously thermally insulates the decarbonization source gas from the high-temperature C2CNT system. Open pore, low-density, thermal insulations are implemented as membranes that facilitate effective CO 2 diffusion for high-temperature decarbonization.
