查询词典 circuit breaker

During the motion process, the stagnation and back commutation occur and worsen the performances of circuit breaker. According to the real interruption process, a three-dimensional(3-D) model of arc motion under the effect of external magnetic field is built based on magnetohydrodynamic, which can predict the restriking phenomena. With air vents opened to 60%, the restriking phenomena occur under 3mT magnetic field; when the magnetic field is increased to 5mT, the restriking phenomena disappears.

该文以磁流体动力学为基础建立了三维空气电弧等离子体在外部磁场作用下运动的数学模型，此模型可以预测电弧的重击穿现象，并发现当灭弧室的出口面积为60%时，电弧在3mT磁场的作用下运动时出现了重击穿现象，而当磁场增大到5mT时重击穿现象消失。
