摘要:

我们的特点是样品的金属氧化物电阻器和测量其击穿电压在液体氩气中施加高电压(HV)脉冲超过3秒的时间。该测试模拟高压分压器链中发生击穿时的情况,电阻两端的电压从静态值迅速上升到更高的值。所有电阻器在液态氩中的击穿电压均高于其在室温空气中的供应商额定值。失效模式从完全破坏到涂层损坏。在击穿不是灾难性的情况下,随后的击穿电压在随后的测量运行中较低。一种电阻器类型可承受131kV脉冲,这是测试设置的极限。

英文摘要:

We characterized a sample of metal-oxide resistors and measured their breakdown voltage in liquid argon by applying high voltage (HV) pulses over a 3 second period. This test mimics the situation in a HV-divider chain when a breakdown occurs and the voltage across resistors rapidly rise from the static value to much higher values. All resistors had higher breakdown voltages in liquid argon than their vendor ratings in air at room temperature. Failure modes range from full destruction to coating damage. In cases where breakdown was not catastrophic, subsequent breakdown voltages were lower in subsequent measuring runs. One resistor type withstands 131\,kV pulses, the limit of the test setup.
