Description

Technical Field

[0001] This utility model relates to the field of high-voltage switch housing processing technology, and more specifically, it relates to a high-voltage switch housing port cutting device. Background Technology

[0002] High-voltage switches are metal-enclosed switchgear and control equipment that uses at least a part of a gas with a pressure higher than atmospheric pressure as the insulating medium. The switchgear is completely enclosed in a grounded metal shell, which is filled with SF6 insulating gas at a certain pressure. Therefore, the sealing performance of the switch shell is particularly important, that is, the connection points must be able to ensure a tight seal when the high-voltage switch shell is processed.

[0003] Currently used cutting mechanisms, especially those for cutting pipes along an inclined direction, typically have a movable blade in one direction to cut from one side. This cutting method uses pressure applied to the blade for entry, which, combined with the high temperature during cutting, can easily deform the cut surface, thus affecting the subsequent connection of the pipe ends. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a high-voltage switch housing port cutting device with a cut surface that is not easily deformed.
