Layered anti-aging insulating cover for solid insulating ring main unit

Abstract

The invention discloses a layered anti-aging insulation cover for a solid insulation ring main unit, and belongs to the field of solid insulation ring main units. The insulating cover comprises an insulating sleeve body, and the lower end of the insulating sleeve body is fixedly connected with a bus inlet pipe. A nanometer sterilization layer and a carbon fiber are used, so when the insulating cover is accidentally bumped, fungi or bacteria attached to a wound can be effectively prevented from continuing to spread into the epoxy resin insulating layer, and the wound is prevented from continuously enlarging into the epoxy resin insulating layer, thereby effectively preventing the enlarging of the biological aging range, and decreasing the aging speed of the insulating sleeve body. Meanwhile, the insulating cover is provided with a high heat conduction layer and a heat radiation film, so the heat generated by the switch assembly can be effectively conducted to the outside, the depositionof the heat in the insulation sleeve body is reduced, the benign dissipation of heat inside and outside the insulation sleeve body can be effectively maintained, and the service life of the insulation sleeve body is prolonged.

Description

technical field [0001] The invention relates to the field of solid insulation ring network cabinets, and more specifically relates to a layered anti-aging insulation cover for solid insulation ring network cabinets. Background technique [0002] The solid insulated ring network cabinet is a ring network cabinet that uses solid insulating materials as the main insulating medium. The main conductive circuits such as the vacuum interrupter and its conductive connections, isolating switches, grounding switches, main busbars, and branch busbars are single or combined with solid insulation. The insulating medium is encapsulated into one or several fully insulated and fully sealed modules with certain functions that can be recombined or expanded. Grounded ring main unit. [0003] At present, my country's solid insulated ring network cabinet has entered a mature stage of development. Common solid insulating materials include: SMC, DMC and other thermosetting insulating materials, ...

AI Technical Summary

Problems solved by technology

[0006] However, during the installation process of the existing solid insulated ring main unit, the insulation cover may be accidentally broken or scratched. At the same time, during the use process, due to long-term power frequency vibration, Cracking occurs due to the influence of the solid insulation ring network cabinet, thus forming a "wound". The "wound" is directly exposed to the air of the solid insulation ring network cabinet. When the solid insulation ring network cabinet is in use, the insulation cover will absorb its internal switching elements. The heat generated will cause the temperature of the insulation cover itself to be high, making the "wound" part very easy to be oxidized, which will accelerate the aging of the insulation cover. At the same time, fungi in the air will also attach to the "wound", causing biological Aging, under multiple aging effects, the service life of the insulating cover will be shortened sharply
