Northwest power grid company 25 measures evening dresses uk a full range of 750,000 volts of power transmission and transformation equipment hidden quality troubleshooting
National grid company height attention Northwest 750,000 v lose variable electric device quality problem, this year February, national grid company specifically Organization held “Northwest 750,000 v device quality problem informed analysis will”, in-depth research analysis Northwest 750,000 v grid cast games yilai, main once device in installed debugging, and junction test and device run, links exposed out of device quality problem, made Xia stage Northwest 750,000 v lose variable electric device quality problem rectification and reform programme, further strengthening 750,000 v device network quality management, Ensuring safe operation of power grids.
conscientiously Northwest power grid company national grid company deployment requirements, full in-depth analysis of prom dresses under 100 750,000 in recent years volt power transmission problems in equipment, grid design to new equipment commissioning process key points, key link, as “five unification” principle, proposes technical specifications and measures. Organization five Northwestern provinces (autonomous regions) and their subordinate departments and units of the company, combined with 750,000 volts to is under construction and soon begins construction project, from planning and design, equipment, equipment manufacturing, construction and installation, test and acceptance of the transfer, for transport equipment run 6 stages, adopted 25 measures against hidden quality investigation and rectification work for all aspects of device.
five measures in the planning and design phases: feasibility study and preliminary design of extension project of strengthening new depth; strengthening of equipment design; strengthening first the first set of product design margin check; conduct a comprehensive safety evaluation work; increased gradually Northwest 750,000 volts power level of equipment. In device tender stage take four item measures: research device tender new mechanism, from source improve device quality; will 750,000 v device fault analysis results application to tender process in the, on fault rate higher of device take extended warranty period of measures; strengthening on first Taiwan first sets device design aspects of assessment, comments on marked focus placed in key components, and insulation material selection, aspects; established supplier, and prison made party quality dates back system. Equipment manufacturing stage four-pronged approach: to strengthen the technical supervision work of the main equipment manufacturing; combination of technical supervision and supervision, research supervision management mechanism; expand range in mill supervision, the test report must have an owner field witnessed; equipment supervision work organization “look” checks. Three measures in the construction and installation phase of transport: construction management, improve construction quality; strengthening the primary transportation management, ensure transport safety; development guide for power transmission and transformation equipment installation process, strengthen the management of field equipment installation. Test and acceptance of the transfer stage taking three measures: again analysis of transformer equipment transfer test standard study, improving field transfer test standard; strengthening acceptance of power transmission line to prevent failure in accordance with the “five unification” requirement and 750,000 kV transmission project is commissioned, expert assessment before the commissioning of the work done within the organization network, perfect the evaluation rules. In device run stage take six item measures: deepening implementation Northwest 750,000 v grid security assessment rectification and reform measures; do new cast device charged monitoring and infrared temperature measurement work, improve run monitoring level; strictly implementation State overhaul provisions, do device technology supervision, and State evaluation, work; continued do has occurred quality problem of analysis informed, formation fault analysis compilation; further increased first-line personnel skills training; combination on fault device causes of again analysis, on has bid has not been supply of products made rectification and reform measures.
2005 years, 750,000 volts of power transmission and transformation equipment quality problem in the Northwest has been more prominent, a total of 49 quality problems, mainly in 2008-2010 and transformers (reactor) class, high-voltage switch equipment, account for more than 80%.
