failure of insulation的意思|示意

The cause of failure in high-voltage switch cabinet model 35KV is analyzed from insulation and structure and some countermeasures are introduced in order to avoid such failure.

主要从绝缘及结构两方面分析了35kV小车式高压开关柜易发故障的原因；介绍了为避免类似故障发生可采取的对策。

The feature extraction of partial discharge signal of transformer is the front research project in online monitoring and diagnosing high voltage insulation failure.

大型电力变压器局部放电信号的特征提取是电气设备绝缘在线监测及故障诊断技术领域的前沿研究课题。

NOTE 2 Failure of basic insulation is not considered likely to occur in normal use.

注2：不考虑在正常使用中可能发生的基本绝缘失效。

The temperature rise of electrical insulation, other than that of windings, is determined on the surface of the insulation at places where failure could cause.

除绕组绝缘温升外，其他电气绝缘的温升是在其绝缘体的表面上来确定，其位置是可能引起下列故障的位置。

However, Pulse Width Modulation (PWM) which was input from inverter is characterized by steep rising edge and high frequency, resulting in the too early failure of motor insulation.

然而，逆变器输出的PWM(脉冲宽度调制)连续高压脉冲的上升沿很陡、频率很高，导致在脉冲电压下牵引电机绝缘过早失效。

The general failure model and mechanism of circuit break, loose contact, instant break, male insulation, short-circuit, false matching, poor fix and bad seal were discussed.

阐述了断路、接触不良、瞬断、绝缘不良、短路、误配线、固定不良和密封不良等常见失效模式和失效机理。
