Corrugated pipe assembly, vacuum arc-extinguishing chamber and vacuum circuit breaker

The invention relates to the technical field of corrugated pipes, in particular to a corrugated pipe assembly, a vacuum arc-extinguishing chamber and a vacuum circuit breaker. The corrugated pipe assembly comprises a corrugated pipe main body, wherein corrugations for fixing are respectively arranged at two axial ends of the corrugated pipe main body; and flanges which are arranged at the two axial ends of the corrugated pipe main body, wherein inner ring grooves are formed in the inner circumferential faces of the flanges; the corrugations for fixing are embedded into the inner ring groove, and the two root portions of the corrugations for fixing are fixed to the flanges. The corrugations for fixing are embedded into the inner ring grooves of the flanges; the two root parts of each corrugations are fixed on the flanges; the effect of integrating corrugations at the end part of the corrugated pipe main body with the flanges is achieved, therefore, the stress of the end part of the corrugated pipe main body is
