Will C4F7N replace sulfur hexafluoride gas as an insulating medium?
Perhaps many practitioners in the power industry have found that many places with sulfur hexafluoride gas have been replaced by C4F7N in recent years, and they will have this question, will sf6 be used in the future, and will it be replaced by C4F7N? To know if sulfur hexafluoride is really replaced. We should first understand the respective properties of these two insulating gases.
First of all, C4F7N gas is an organic compound, and now it is used as an insulating medium in some special environments. It is colorless, odorless, and mainly has the following properties:
1. High insulation performance :C4F7N has good insulation performance at high temperature and pressure, and can be used as an insulating medium for power equipment.
2. Low toxicity: Compared with other gases,C4F7N has very low toxicity and has little impact on the human body and living environment.
3. High chemical stability :C4F7N has good tolerance to most chemical substances and is not easy to react.
4. Low temperature thermal conductivity :C4F7N has low thermal conductivity and can be used to maintain the stability of low temperature environment.
Will C4F7N really replace SF6 gas?
The answer is of course no, at this stage it will not directly replace SF6 gas as an insulating medium. SF6 gas is widely used in some high-voltage power equipment because of its good insulation performance and strong arc extinguishing ability. The application of C4F7N is mainly in some special occasions, such as insulation requirements in high temperature, high pressure, and high humidity environments. In some specific application areas,C4F7N may be chosen as a replacement, but it is not suitable for all cases. The selection of insulating media needs to be evaluated and decided according to the specific application requirements and safety standards.
