四川：8座换流站“体检”完成 冬季用电有保障|人妻被黑人猛烈进入A片
中新网成都11月29日电 (刘忠俊 郑自豪)11月29日，四川省凉山州境内的布拖±800千伏特高压换流站双极直流系统已完成解锁，四川省内8座换流站2025年度集中检修工作全部完成。此次集中检修有效提升了主干电网设备健康水平，为迎峰度冬电力稳定供应奠定了坚实基础。
据了解，8座换流站的年度检修安排在春、秋两季电网负荷相对较低的时段分批开展。从春季复龙±800千伏特高压换流站率先启动，到秋末布拖±800千伏特高压换流站收官，总时长累计52天。国网四川电力先后累计投入检修人员3300余人次，高效完成数百项检修及技改任务，实现对关键输电枢纽的全面“体检”与效能提升。
在雅砻江、布拖等±800千伏特高压换流站，国网四川电力试点应用换流变主动防御系统，将防爆燃保护从被动应对转向主动干预，显著提升设备本质安全水平。针对复龙±800千伏特高压换流站、德阳±500千伏换流站等投运时间较长的换流站，检修团队“一站一策”更新关键部件，有效延长设备使用寿命，夯实跨区输电通道稳定运行基础。
国网四川直流公司提供的数据显示，截至目前，四川直流输电通道已累计外送电能超1.6万亿千瓦时。本次集中检修的顺利完成，进一步增强了电网运行可靠性，为四川省内及华东、华中地区冬季电力供应提供了有力保障。(完)
