不均匀的

On the basis of experiment analyses we would got that, When arc met with chute, it was blocked and had a stagnation, this made hot gas flow incrase near the chute; After arc went into the chute, mental vapor from arc root would lower the dielectric strength near the chute, meanwhile, High value of arc voltage and the corase face of the chute made electric strength increase. These factors might give rise to local restriking near the chute, and made arc voltage drop suddenly.

总结实验结果并加以分析，本文提出了这样的观点：电弧进入栅片时，在入口处受阻后的停滞，会使该区域的热气流增加；进入栅片后，弧根蒸发的金属蒸汽、电弧热气流会降低栅片入口区域的介质强度；电弧被栅片分割后，电压急剧上升，再加上栅片表面的不均匀会使局部区域的电场强度显著增加，这些因素的综合作用会导致电弧在栅片入口附近发生局部重击穿，引起电弧电压电压跌落。

三项埋入式电极盐浴炉采用盐类作加热剂，根据不同的工作温度，可选用不同成份的盐或混合盐，盐在熔化前是不导电的，因此盐浴炉使用时必须使用起动电极溶化，由于电流通过导电的溶盐不断产生热量，故可保持溶化状态，因电极在电磁力的作用下，通过自然对流和电磁搅拌而使熔盐不断循环，故可迅速和均匀的加热工件。

The influence of impulse voltage waveshape on particle-initiated breakdown voltage of a GIS system in SF6 and SF6/Air mixtures is reported. The results are compared with the characteristics of air gaps. For the SF6 gaps, breakdown voltage depends on wave-front duration but almost independs on wavetail duration. For the gaps in SF6/Air mixtures, the influence of impulse waveshape also depends on SF6 contents and electrical field non-uniformity
