Description

Technical Field

[0001] The utility model relates to the technical field of solid-sealed poles, in particular to a loose-proof solid-sealed pole for a vacuum interrupter. Background Art

[0002] The sealed pole is an integral component formed by embedding the vacuum interrupter and the conductive parts related to the circuit breaker into solid insulating material. The solid insulating material shell can reduce the impact of the external environment on the vacuum interrupter and ensure that the vacuum interrupter can work normally.

[0003] During use, it is inconvenient to replace the conductive parts inside the existing sealed poles. For example, the detachable sealed pole described in the patent publication number CN 220041704 U provides a channel for replacing the vacuum interrupter through a window, thereby realizing the disassembly and replacement of the conductive parts inside the sealed pole. When the window is closed, it can effectively prevent external dust and moisture from entering the accommodating cavity and contaminating the interrupter, thereby reducing the impact of the external environment on the performance of the vacuum interrupter. However, when the sealed pole is in use, it works by connecting cables at the static outlet end and the dynamic outlet end. During long-term use, it is easy to become loose, causing the connection to be disconnected, which affects other devices.

[0004] Based on this, a vacuum interrupter sealed pole with an anti-loosening feature is now provided to eliminate the drawbacks of existing sealed poles. Utility Model Content
