insulation breakdown

基本解释

Under high frequency continuous impulse, partial discharge is one of the most important factors, which even cause insulation breakdown of PWM inverter-fed motors.
局部放电是引起PWM变频电机绝缘在高频连续脉冲条件下发生老化的重要因素之一，严重时将导致电机绝缘的击穿。
Air breakdown for composite alternating and direct voltages in a rod plane gap at standard atmospheric conditions were studied to understand insulation breakdown in electrical appliances.
为了分析实际运行中稳态预电压对电力设备绝缘的影响，研究了在标准气象条件下，棒-板间隙的操作冲击特性和交直流预电压的关系。
In the series-resonant state, when the test insulation breakdown weaknesses , the circuit is immediately off the harmonic , the loop current is rapidly decreased to normal test current of 1 / Q.
在串联谐振状态，当试品的绝缘弱点被击穿时，电路立即脱谐，回路电流迅速下降为正常试验电流的1/Q。
