So the development of self - energy sf6 cb is very important . in the paper , the math model of arc - quenching chamber air - pressure character is built on the base of 126kv / 31 . 5ka self - energy sf6 cb ' s exploiting , then the theory analysis and calculation is deeply been done for cylinder radius , nozzle spout radius and opening position of moved contact that they have the essential effect for the use of arc energy in the course of opening . arc - quenching chamber parameter is confirmed according to the request of full opening and fault opening when the cb is opening
本文针对126kv31 . 5ka自能式sf _ 6断路器的研制，建立了相应的灭弧室气压特性数学模型，对自能式sf _ 6断路器开断过程中电弧能量利用有重要影响的灭弧室缸径、喷口直径、动触杆开口位置进行了详细深入的理论分析和计算，并根据断路器开断中的满容量开断和近区故障开断的要求确定了灭弧室参数。
