SF6/N2 gas mixture is a temporary choice for SF6 substitute as insulation dielectrics. We made use of the collision ionization concept As an instance the system with the temperature impact over the insulation efficiency of SF6/N2 gasoline mixture. Also, we verified the experimental success on the insulation performance of SF6/N2 gas combination by theoretical Investigation, which was considered one of SF6 option decisions, underneath superior pressure and low temperature at −35℃, −18℃ and 0℃. The sphere-plate and rod-plate aluminum electrodes have been applied to build the uniform and non-uniform electric powered subject. The polarity effect of breakdown voltage of SF6/N2 and pure SF6 along with the electric subject coefficient is usually received. It’s located that the electrical field sensitivity element of SF6/N2 at 0.seven MPa with 20% SF6 is reduce than that of SF6 at 0.4 MPa beneath a constructive impulse voltage. However, the electrical subject sensitivity component of SF6/N2 or SF6 is similar under a detrimental voltage. LV Engineers In the meantime, it truly is located which the p-T characteristics of true gases deviate from ideal gases, which gets to be better as the temperature lowers. The compressibility variable of SF6/N2 gas mixture with stress of 0.7 MPa and SF6mole ratio of twenty% is obtained with the exam. The compressibility variable raises linearly While using the lower of temperature from 0℃ to −35℃. © 2017, High Voltage Engineering Editorial Division of CEPRI. All proper reserved.
Development in Researching Electrical Attributes of Surroundings-pleasant
So that you can critique the analysis development inside the electrical Homes of environment-helpful insulating gases recently, and also to progress the investigation and software of new gases, We now have refined two tips on how to evaluate gas insulation general performance and the appropriate situations from 3 areas of discharge mechanism, discharge qualities, and new gas research, specifically vital lowered area energy and breakdown field strength. The influences of neighborhood uneven electrical subject, strain, temperature, and gas combination on electrical Attributes are acquired, which is useful for analyzing the electrical Qualities of latest gas. To resolve the situation of very poor performance of latest fuel investigation, the speculation of efficiency prediction according to microscopic parameters of gasoline molecules are introduced. Finally, two Instructions are set forward while in the exploration of surroundings-welcoming fuel. 1 is always to enhance the insulation general performance considering the coupling influence aspects in the practical equipment. The next is toexplore new gases with improved electrical Houses based upon the speculation of molecular structure parameters prediction. © 2018, High Voltage Engineering Editorial Department of CEPRI.
