Abstract
Description
Technical Field

[0002] Laying refers to the installation method of cables from one place to another. The laying and protection of high-voltage cables are key links to ensure stable and safe power transmission. During the cable laying process of the power system, various factors such as short circuit and grounding fault may cause damage to the cable and failure of the power system. In order to achieve the effect of safety protection, corresponding high-voltage protection devices are usually installed at the cable laying site. Common high-voltage protection devices include suspension insulators, post insulators, porcelain insulators and enclosed fuses. In the power system, fuses are used as a commonly used protection device to cut off the circuit when the current is overloaded, protect electrical equipment and lines from damage, and achieve the effect of high-voltage protection during cable laying.
[0003] However, in the actual laying process, since the number of enclosed fuses required at the installation location is more than one, and the distance between two adjacent enclosed fuses is generally relatively small, there is a lack of corresponding isolation components between the two adjacent enclosed fuses, and the separation operation cannot be achieved, which will cause mutual interference between the two adjacent enclosed fuses, especially in the case of discharge, the discharge of one enclosed fuse will cause a linkage effect on the adjacent enclosed fuse, causing losses. In view of this, we proposed a high-voltage protection device for cable laying. Utility Model Content
