Problems solved by technology

In order to improve the safety of the product, the current solid-state ring network cabinet uses epoxy resin to implement integrated pouring of the module unit bus system, cable connectors, and vacuum interrupter to form an insulating shell of epoxy resin, but due to the ring network Oxygen resin has certain limitations in terms of mechanical strength and electrical insulation performance. The thickness of the casting layer is roughly 10-12mm, so that although the solid-state ring network cabinet realizes the integration of devices, its volume is still large and is insulated from gas. Compared with the ring network cabinet, the quality has been improved, but the volume has not been reduced, which limits the application range of the solid state ring network cabinet.

Abstract

Belonging to the technical field of solid-sealed polar poles, the invention relates to an insulating material for solid-sealed polar poles, a solid-sealed polar pole and a preparation method thereof. The insulating material for solid-sealed polar poles is prepared from the following components by weight percentage: 25.0%-28.0% of nylon, 48.0%-51.5% of glass fiber, 2.0%-3.0% of a toughening agent, 20.0%-23.0% of a flame retardant, 0.2% of an antioxidant, 0.3% of a lubricant, and 1.0% of color masterbatch. The toughening agent is ethylene propylene diene monomer; the lubricant is a fatty acid ester lubricant; and the color masterbatch is carbon black. The insulating material for solid-sealed polar poles provided by the invention adopts nylon and glass fiber, guarantees the mechanical strength and electrical properties, at the same time can effectively reduce the thickness of an insulation shell outside the solid-sealed polar pole, and the solid-sealed polar pole insulation shell prepared from the insulating material for solid-sealed polar poles provided by the invention only requires a thickness of 3-5mm.

Description

technical field [0001] The invention relates to an insulating material for a solid-sealed pole, a solid-sealed pole and a preparation method thereof, belonging to the technical field of solid-sealed poles. Background technique [0002] Most of the gas insulation of medium voltage ring network cabinets currently adopts SF 6 gas, SF 6 The chemical properties of the gas are very stable, with excellent insulation and arc extinguishing properties, and are widely used in power equipment. SF 6 The gas insulated switchgear is small in size and compact in structure, not affected by external environmental factors, and has strong adaptability. However, SF 6 Gas is one of the six internationally recognized greenhouse gases. From the perspective of environmental protection, SF should be used less or not 6 gas. With the advancement of insulating material technology, solid-state ring network cabinets based on epoxy resin have been greatly developed. [0003] With the development of ...
