The internal discharge with high temperature of the type on transformer fault is certained after analysis of the transformer oils and gas chromatographing to insulations burning of No. 2 main transformer in Pudong Substation. 通过对浦东变2号主变压器烧损后的检测和油、气样色谱分析,确定了变压器故障类型为内部高温放电。
Subsequently, the residual proteins were removed by shaking with organic solvents, treating with adsorbent and chromatographing with ion-exchange resin. 然后再采用有机溶剂沉淀法,活化浮石土吸附法以及离子交换树脂等,以去除少量的残余蛋白。
