As the stateFully Insulated ring mesh cabinetsThe performance requirements are more and more high, and more and more attention has been paid to the high reliability of environmental protection ring cabinets. The future development trend of solid insulated ring network Cabinet technology can be divided into the following four aspects.

1. Development of a new high performance thermal insulation material

Epoxy resin as a solid insulated ring cabinet used in an insulating material, although its performance is very superior, but in the pouring ceramic vacuum arc extinguishing chamber, there is still the problem of cracking of the original parts. Therefore, it is necessary to develop a high performance biodegradable epoxy resin that completely exceeds the characteristics of existing epoxy resins.

2014, the journal Science published an article on the discovery of new recyclable thermosetting polymers. Significant progress has been made in the area of recyclable thermosetting plastics (Poly six hydrogen tri-piperazine). This paper points out that this new type of polymer can dissolve in strong acid, destroy its original physical properties, make it degrade effectively, then separate the single molecular structure, produce new products through the newly processed process, and realize the recycling of materials. This polymer has superior recyclable properties and is likely to replace non-recyclable thermosetting plastics within five years. Recyclable thermosetting materials will be used for all new products produced over the next 10 years.

2. Development of high efficiency casting technology

Traditional epoxy resin pouring process is time-consuming and laborious, low efficiency and high cost. In order to solve the problem of high cost and low efficiency, it is necessary to develop efficient pouring technology. In addition to the improvement of the catalyst, the flow hardening analysis technology is also used. By optimizing the composition of the resin catalyst and controlling the temperature of the metal mold, the resin in the metal mold can react well from the upper part of the injection port, make the resin shrink during the hardening process, and provide the pressure of the non-hardened liquid resin to the injection port, so as to obtain the non-deformed castings. Parts. High-efficiency pouring technology, one day pouring 8~12 times, a metal mold can produce 14 pouring parts. Productivity can be increased by 8 to 160 times times compared to the past. Through the development of these technologies, many low-cost, high-quality castings can be produced in a short period of time.

3. Development of interface connections between built-in components

The solid insulated ring cabinet is the main circuit part of the main circuit wire and the placement element is poured with a fixed insulator, so the connection between the built-in components is not flexible. Therefore, it is necessary to standardize the connecting conductors of various casting elements and rationalize the overall composition of the ring cabinet. The connecting conductor must also pour epoxy resin, so a reasonable product with a certain degree of freedom is required to maintain the connecting part of the casting body. For this reason, the interface connection technology of silicone rubber compression connected casting body and conductor connection part is developed. By using this interface connection method, the size of the connector can be reduced, the connection wire combined with the receiver should be standardized, the receiving element should be configured reasonably, and the whole structure of the solid insulating ring should be miniaturized.
