Closing resistor carbon ceramic material for high-voltage circuit breaker and preparation method of closing resistor carbon ceramic material
The invention discloses a closing resistor carbon ceramic material for a high-voltage circuit breaker and a preparation method thereof, and relates to the field of electrical ceramics, and the preparation method comprises the following steps: S1, ball-milling alpha alumina, cristobalite, kaolin and a carbon material to obtain ball-milled slurry; s2, the ball-milled slurry is dried and sieved, and raw material powder is obtained; s3, putting the raw material powder into a mold, and sintering to obtain a sintered body; and S4, performing post-treatment on the sintered body, and spraying a coating to obtain the closing resistor disc. According to the preparation method, the required analytically pure aluminum oxide raw material and carbon material are selected, so that on one hand, research on each component is facilitated, and a proper raw material formula system is analyzed and screened, and on the other hand, compared with the prior art that all the raw materials are mineral raw materials, the cost is reduced; the problems that excessive impurities are introduced, and the performance of the resistor discs produced in batches is unstable due to uncontrollable raw material components are solved.
本发明公开了一种高压断路器用合闸电阻碳陶瓷材料及其制备方法，涉及电工陶瓷领域，包括以下步骤：S1：将α氧化铝、方石英、高岭土和碳材料球磨，得到球磨浆料；S2：将球磨浆料烘干，过筛，得到原料粉体；S3：取原料粉体装入模具中，进行烧结，得到烧成体；S4：对烧成体后处理、涂层喷涂，制得合闸电阻片。本发明选择所需要分析纯的氧化铝原料、碳材料，一方面便于开展各组成部分的研究，分析筛选出做适合的原料配方体系，另一方面相较于现有技术中原料全部使用矿物原料，避免了引入过多杂质、因原料组分不可控导致批量生产的电阻片性能不稳定等问题。
