Insulating housing with integrated functions and manufacturing method therefor

Abstract

An insulating housing with integrated functions comprises a barrel-shaped shell, an interior wall of which being provided with a protruded or recessed uneven texture configured to increase a creepage distance between both axial ends of the barrel-shaped shell, the path of the creepage distance formed by the protruded or recessed uneven texture having more than two flyover or bypass sub-paths, such that the creepage distance is increased, and the voltage withstanding is increased. Meanwhile, by employing a construction of creepage-increasing rings, not only the creepage distance is increased greatly, but also the barrel-shaped shell is avoided from full-interior wall contamination by metal vapor evapotranspiration. Thus, under the double effects of a greater creepage distance and a greater proportion of uncontaminated area, the voltage withstanding and after arcing insulation level of the insulating housing with integrated functions are improved greatly, while the after arcing electric insulation level of the vacuum interrupter is not decreased, such that the insulating housing with integrated functions and the vacuum interrupter is developing towards high voltage and ultra-high voltage.
