Research on microcontrol technology of gas insulated switch solenoid valve based on environmental monitoring characteristics

with the application of GIS in transmission line more and more widely, people pay more attention to the line insulation problems caused by VFTO and the interference problems caused by the later equipment. Based on the full analysis of the working process of gas insulated switch, this paper constructs the theoretical model of the switch, comprehensively considers the influence of the switch resistance on VFTO, and discusses the influence of the working speed of the switch solenoid valve on GIS, especially on the residual charge in the line and the number of reburning. At the same time, this paper considers the influence of the environment change with the characteristics of lightning stroke on the disconnector, and considers the influence of MOA and other components on VFTO in the process of establishing the disconnector, and establishes its dynamic model. The experimental results show that the model is effective, which has a certain guiding significance for the construction and operation of GIS Substation in China.
