The driving force for this research is to enable power electronic components to operate in pressurized dielectric environment. The intended application is the converters for operation down to 3,000 meters ocean depth, primarily for subsea oil and gas processing. The paper focuses on the needed modifications to a general purpose gate driver for IGBT （insulated gate bipolar transistors） that will give pressure tolerance. Adaptations and modifications of the individual driver components are presented.The results from preliminary testing are promising, which shows that the considered adaptations give feasible solutions.展开更多
在某油田作业时,我厂生产的一只2i n×105M P a弯头失效,据用户统计,其工作时间累计近500h。该产品材质为20C r N i M o合金钢,制造流程为：原材料入厂检验→下料→加热镦粗→镗孔→加热揻弯→调质→粗加工→渗碳淬火→回火→精加...在某油田作业时,我厂生产的一只2i n×105M P a弯头失效,据用户统计,其工作时间累计近500h。该产品材质为20C r N i M o合金钢,制造流程为：原材料入厂检验→下料→加热镦粗→镗孔→加热揻弯→调质→粗加工→渗碳淬火→回火→精加工→磁粉无损检测→装配。出厂前按《高压流体控制产品出厂实验程序》的要求进行158MPa本体强度试验,检测结果符合技术要求。为了找到失效原因,对产品解剖分析。展开更多
