Abstract
This utility model discloses an insulation protection device for high-voltage switchgear, relating to the technical field of insulation protection devices. It includes an insulating sleeve one and an insulating sleeve two inserted together. One end of the insulating sleeve one is slidably provided with a fastening sleeve for securing the insulating sleeve two. At least two sets of equidistantly distributed limiting slots are spaced apart on the outer wall of the insulating sleeve one. The insulating sleeve one and the insulating sleeve two are inserted together, and are fixed by engaging with the positioning end using the limiting slots. The fastening sleeve then secures both, providing reliable electrical insulation protection for the cable connection. When it is necessary to disassemble the insulating sleeve one and the insulating sleeve two, the sliding fastening sleeve returns to its original position. At this time, the positioning spring drives the hemispherical head into the limiting slot, and the hemispherical head can press down on the positioning end, thereby releasing the engagement between the positioning end and the limiting slot, achieving quick disassembly of the insulating sleeve one and the insulating sleeve two. The device has a compact structure, is easy to install, and is reliable and not easily loosened during use.
