Description

Technical Field

[0001] The utility model relates to the technical field of vacuum interrupter chambers, in particular to a vacuum interrupter chamber opening tool. Background Art

[0002] To ensure excellent insulation performance within the vacuum interrupter, all internal components are constructed of materials with low gas content. However, during current interruption, due to the high surface temperature, a large amount of gas may be released, affecting the interrupter's interrupting capacity. Therefore, effective measures such as power frequency voltage aging are necessary. During power frequency aging, the moving contacts must be separated by a certain distance. Because the interior of the interrupter is in a vacuum state and there is a pressure difference of 1 atmosphere inside and outside, there is a certain self-closing force, so certain tools are required to separate them.

[0003] The prior art pull-out tooling is as follows Figure 1 As shown, the handle is hinged with a hook and a support rod. The hook connects to an adapter, which in turn connects to the vacuum interrupter's movable conductive rod. The lower end of the support rod is fixedly connected to a sleeve placed on the movable end cover of the vacuum interrupter. To open the tool, the handle is pressed, causing the hook to rise and lift the movable conductive rod. During the opening process, the handle generates a lateral force that can easily shift the vacuum interrupter. Opening a single vacuum interrupter may require several repetitive operations, which is inefficient. For some small and lightweight vacuum interrupters, the bottom friction is minimal, making them prone to slipping, which can damage the product during opening. Utility Model Content
