Abstract

The invention discloses a material for a secondary fusion equipment shell, and mainly solves the problems that an existing common epoxy resin material is relatively low in physical property (such as impact strength) in one aspect and relatively high in specific gravity in another aspect, and can hardly meet requirements of secondary fusion equipment. The material is characterized by being preparedfrom the following components in percentage by weight: 41 to 61 percent of PET, 3 to 6 percent of a red phosphorus flame retardant, 15 to 21 percent of a glass fiber, 20 to 30 percent of mica and thebalance of a processing aid and a stabilizer. The invention provides the material for the secondary fusion equipment shell, and the secondary fusion equipment shell made of the material has the characteristics of relatively small specific gravity and good physical properties.

Description

technical field [0001] The invention relates to the field of materials for manufacturing high-voltage electrical appliances, in particular to materials for shells of primary and secondary fusion equipment. Background technique [0002] State Grid aims to create "safety, reliability, integration and efficiency" as its technical goal, takes demand as the guide, and detection as the guarantee. For the pole-mounted circuit breakers in the construction and transformation of the distribution network, the standardization of overall design, the independence of functional modules, and the exchange of equipment The idea of ​​flexibility is to give priority to solving the problems faced in the construction of distribution automation, such as remote signal jitter, compatibility and scalability of primary and secondary interfaces, and the new line loss collection function of the terminal. It is proposed that the circuit breaker on the pole should be set with high precision, A wide range ...
