广州电网10kV SF_6全绝缘环网柜一次送样检测结果分析

Analysis of 10kV SF_6 Fully Insulated Ring Network Cabinet Admission Testing Result in Guangzhou Power Grid

送样检测是资产管理关口前移的重要措施,其结果用于评估供应商产品质量和生产、研发能力的品控行为。本文对10k V全绝缘环网柜一次送样检测的送检情况、检验策略进行了描述,并分析了其检验结果,发现不合格项目由多至少依次为短时耐受和峰值耐受电流试验、防护等级验证、机械操作、分合闸时间、回路电阻测量、机械性能试验、雷电冲击试验,说明了当前环网柜供应商仍然是良莠不齐。同时还对送样检测发现的不合格检验项目可能产生的影响和原因进行了详细分析,同时提出了相应的建议。

Admission testing is an significant measure for asset management of Guangzhou Power Grid. It is used to as- sess the supplier＇s product quality, and research ability in quality control. The test strategy of Guangzhou power grid 10kV fully insulated ring network cabinet sample detection inspection situation,described, and analyzed the test results, found unqualified project by turns short -time and peak withstand current test, protection grade verification, mechanical operation, switching time, loop resistance measurement, mechanical performance test, lightning impulse test, shows that the current ring network cabinet supplier is still uneven, some good and some bad. Influence and reason also to send sam- ples detected unqualified projects may have carried out a detailed analysis, and put forward the corresponding suggestion.
