C5F10O gas insulating medium has attracted wide attention in the power industry for its excellent environmental potential and insulation performance. When C5F10O gas is applied in power industry engineering, it will inevitably face the over thermal fault which often occurs inside the equipment. Under the long-term effect of the local over thermal fault, whether C5F10O itself can maintain stability is an important factor to determine its engineering application. However, the thermal stability characteristics of C5F10O and its mixture are still unknown. Therefore, through systematic experimental research on the existing experimental platform of partial over thermal of the gas insulating medium, this paper explores the initial decomposition temperature of 5% C(5)F(10)Oand 95% CO2 mixture, the formation conditions of decomposition components, the relationship between the generation characteristics of decomposition components and fault temperature, and so on. The results show that when the pressure of 5% C5F10O and 95% CO2 is 0.2MPa, the mixture begins to decompose at about 400 degrees to form C3F8 and C3F6. C2F6 and CF4 will be produced at above 500 degrees. The process of C3F6 formation is the endothermic reaction, while the process of C3F8, C2F6 and CF4 formation is an exothermic reaction, which is very beneficial to the formation of C3F6 un- der superheated conditions. As a result, the product concentration shows as C3F6 > C3F8 > C2F6 > CF4, and the rate of product formation is positively correlated with the over thermal fault temperature. The results of this study lay a foundation for the application of C5F10O gas in the electric industry. |
