9月7日,济南轨谈交通6号线首个车站牵引羼杂变电所——济南东站牵混所35kV一样送电见效,为下一步斗殴网送电、热滑考试等专科施工提供了电力保险。
在施工现场,跟着现场退换下达倒闸操作任务,变电所操作主谈主员严格按照送电启动决议,准确推论倒闸操作,牵混所35kV开关柜Ⅰ、Ⅱ段母线奏凯进入分段入手,进入带电入手景象。
牵引羼杂变电所就像地铁供电系统的“腹黑”,通过整流变压器、整流器和直流柜将外部电网提供的35千伏一样高压电变换为1500伏直流电,运送到电客车上方架设的斗殴网,给电客车供电。另外,在牵引羼杂变电所内,通过配力变压器将外部电网提供的35千伏一样高压电变换为400伏一样电,给地铁站各个开荒提供电源。
为确保济南轨谈交通6号线首座变电所送电见效,济南轨谈交通集团建投公司6号线情势部会同中铁上投、中铁电气化局等参建单元组建了现场保险队伍,编制了受电启动决议,送电前严格按照送电决议全靠近接工夫法度,对各项开荒的功能、绝缘进行了屡次查验和测试,同期对参与送电东谈主员进行安全工夫交底,模拟演练送电要领和门径,作念好送电前预核查及变电所圭臬化成就等职责。参建东谈主员克服多专科交叉功课、既有清爽接口工艺复杂、工期紧任务重等多项辛勤,确保了这次送电职责圆满见效。受电见效后,工夫东谈主员对所内主变压器、断路器等枢纽开荒进行顾惜查验,效劳透露各项参数达标,开荒运转宽泛。
济南轨谈交通6号线是一语气济南主城区的东西向骨主线,串联济南西站、济南火车站、济南东站三大交通要津,换乘点多,发射面积广。自清爽开工成就以来,6号线参建雄师,永久保握攻坚克难、敢为东谈主先的职责气魄,工程成就获取了显赫成效。阻抑现在,全线已有32个站点进场施工,22座车站封顶,20个区间双线交融,18座车站终了机电装修进场施工,情势成就稳步高效快速鼓吹。
