Abstract
The ratio of decomposition products with physical meaning is used as quantity: c(SO2F2)/c(SOF2) c(CF4)/c(CO2) and c(CF4+CO2)/c(SO2F2+SOF2) used to treat four different typical defects (metal protrusions air gaps metal particles and...). Maintain the room temperature of 20°C and constant humidity of 40%. Obtain the corresponding relationship between local overheating temperature and decomposition products through experiments. Use temperature controller to control local overheating hot-spot temperature at the fixed value. Experimental temperature range is 200°C~575°C. The power system for C5F10O gas can control the output voltage by adjusting the air pressure of the Marx generator and the main switch. The single-stage charging capacitor of the Marx generator is 40nF and the output pulse rising edge is as fast as 30ns half width is 500ns output pulse amplitude is up to 250kV and short-circuit current can reach 40kA. The order of the generation of the seven decomposition components of C5F10O from easy to difficult or from the high to low is as the follows: CO>C3F6>C2F6>C2F4≈C3F8>CF4. As the frequency increases the dielectric loss tangent of the cardboard at different temperatures also shows the process of first decreasing and then increasing. However for the frequencies ranging from 100 to 103 variation in the tangent of the loss angle is relatively small at the low temperatures while it is relatively large at high temperatures.
