Layered anti-aging insulation cover for solid insulation ring network cabinet

Abstract

The invention discloses a layered anti-aging insulating cover for a solid insulating ring network cabinet, which belongs to the field of solid insulating ring network cabinets. A layered anti-aging insulating cover for a solid insulating ring network cabinet includes an insulating sleeve body, an insulating The lower end of the sleeve body is fixedly connected with the busbar inlet pipe, which can effectively prevent the fungus or bacteria attached to the "wound" from continuing to enter the epoxy resin insulation layer when the insulation cover is accidentally bumped through the use of nano-sterilizing layer and carbon fiber. The effect of spreading, and at the same time inhibiting the "wound" from continuing to grow into the epoxy resin insulation layer, effectively hindering the scope of biological aging, can reduce the aging speed of the insulation sleeve body, and at the same time, the setting of high thermal conductivity layer and heat radiation film can effectively It conducts the heat generated by the switch components to the outside and reduces the heat deposition in the insulating sleeve body, so as to effectively maintain the benign heat distribution inside and outside the insulating sleeve body and improve the service life of the insulating sleeve body.

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
