| description | The present invention provides a method for preparing zinc oxide (ZnO) varistors with a high surge energy tolerance. According to the present invention, the large-capacity zinc oxide varistor preparing method includes the steps of: blending an additive including bismuth oxide powder, antimony oxide powder, iron oxide powder, manganese oxides, and alumina powder; pulverizing the blended additive primarily; mixing zinc oxide powder to the pulverized additive to blend an ingredient composition for a varistor; pulverizing the ingredient composition secondarily; forming the ingredient composition; and sintering the formed ingredient composition. The present invention can prepare the zinc oxide varistor with high reliability and high surge energy tolerance for surge energy such as high power electromagnetic pulses (HPEMP) and direct lightning.
본 발명은 높은 서지에너지 내량을 갖는 ZnO 바리스터의 제조 방법을 제공한다. 본 발명은 산화 비스무스 분말, 산화 안티몬 분말, 철족 산화물 분말, 망간 산화물 및 알루미나 분말로 이루어지는 첨가제를 배합하는 단계; 상기 배합된 첨가제를 1차 분쇄하는 단계; 상기 분쇄된 첨가제에 산화 아연 분말을 혼합하여 바리스터 원료 조성물을 배합하는 단계; 상기 원료 조성물을 2차 분쇄하는 단계; 상기 원료 조성물을 성형하는 단계; 및 상기 성형된 성형체를 소결하는 단계를 포함하는 대용량 산화 아연 바리스터의 제조 방법을 제공한다. 본 발명에 따르면, 직격뢰 또는 고출력전자기펄스(HPEMP; High Power Electro-Magnetic Pulse)와 같은 높은 서지에너지 내량을 갖고 신뢰성 있는 산화아연 바리스터의 제조가 가능하게 된다. |
