Influence of compulsory convection on acetylene gas mass transfer process in insulation oil
In order to optimize the sampling procedure of dissolved gas analysis(DGA),and to improve the universality and accuracy of DGA results,a compulsory convection method was proposed to accelerate the mass transfer process of decomposition gas dissolved in insulating oil.Firstly,the mass transfer process without compulsory convection was studied.And the time gas travels from failure source to sam-pling port was measured.Secondly,the mass transfer process with compulsory convection was studied and corresponding travel time was measured.Plus,the difference between those two travel times was dis-cussed.Thirdly,the difference was studied among the mass transfer processes of different compulsory convection motion periods.The research findings may serve as a reference for the development of online monitoring equipment for bushing.
