Abstract

The invention discloses an insulating material structure and a production method thereof. The insulating material structure is used as an insulating medium of electrical equipment in high-voltage direct-current transmission, and comprises a polymer base layer, wherein a first polydopamine layer, a nano-silver layer and a second polydopamine layer are sequentially arranged on the surface of the polymer base layer from inside out, the nano-silver layer comprises a plurality of nano-silver particles, the range of the particle size RA<g> of the nano-silver particles is as follows: 0<RA<g><100 nm. The insulating material structure can effectively inhibit injection and accumulation of space charges in a polymer insulating medium under high voltage and direct current, reduces electric field distortion, caused by a space-charge effect, in an insulating material, improves the breakdown performance of the insulating material, and thus prolongs the service life of the electrical equipment, achievement is simple, the practicability is high, the safety is high, equipment needed in a production method of the material is simple and easy to obtain, treatment conditions needed in the production method of the material are simple and easy to achieve, and the repeatability is high.

Description

technical field [0001] The present application relates to the technical field of high voltage direct current transmission, in particular to an insulating material structure and a preparation method thereof. Background technique [0002] High-voltage direct current transmission has the characteristics of large transmission capacity, long transmission distance, small loss, low cost, fast adjustment speed, high stability, etc., and is widely used in long-distance and large-capacity power transmission. With the development of my country's power system and the increase of power transmission capacity and transmission distance, the superiority of HVDC transmission in the national power grid will become increasingly prominent. [0003] Polymer insulating materials have the characteristics of low cost, excellent electrical, thermal, and mechanical properties, and are widely used in electrical equipment such as cables, capacitors, and transformers. For example, cross-linked polyethyl...
