Abstract

This utility model relates to a high-temperature resistant and high-voltage resistant electrical insulation device, including a high-temperature resistant insulation plate, an inlaid sleeve, and an inlaid fixing mechanism. The high-temperature resistant insulation plate is set at the entrance of the electrostatic precipitator equipment cavity and the cathode insulation box through the inlaid fixing mechanism. There are two high-temperature resistant insulation plates, which are symmetrically arranged and have an inlaid hole in the center. The inlaid sleeve is installed between the inlaid hole of the high-temperature resistant insulation plate and the head of the cathode rapping shaft. The inlaid fixing mechanism is used to prevent the high-temperature resistant insulation plate from moving, which can significantly reduce the dust accumulation in the insulation box. When the cathode insulation is damaged, it can be easily replaced, improving maintenance safety.
