Description

Technical Field

[0001] The utility model relates to the technical field of capacitor type bushings, in particular to a fixing mechanism and a capacitor type bushing disassembly device. Background Art

[0002] In power systems, capacitor bushings are critical high-voltage equipment that connect electrical equipment of varying voltage levels, such as transformers and circuit breakers. Due to their critical role in power systems, regular maintenance and inspection of capacitor bushings is essential to ensure safe and stable operation. However, traditional bushing disassembly and maintenance procedures present several technical and safety challenges.

[0003] Traditional casing disassembly work usually requires the casing to be placed horizontally. This working condition is highly dangerous and cannot complete the disassembly work for some casings with complex structures. In addition, when the casing is suddenly released during the disassembly process, the casing parts will suddenly pop out, which not only damages the equipment but also poses a serious threat to surrounding personnel.

[0013] The beneficial effects of the fixing mechanism of the present invention are as follows: by adopting an equilateral triangle structure composed of the first vertical pole, the second vertical pole and the third vertical pole, the stability of the structure is achieved, and the safety of the sleeve disassembly process is ensured. At the same time, the coordinated action of the jack and the clamping assembly effectively controls the disassembly process and avoids the risk of sudden popping out of the sleeve component.
