新闻摘要：5月7日20时45分，±660千伏银东直流输电系统双极一次性解锁成功，银川东换流站全面恢复运行，标志着该站2026年度直流系统综合检修工作顺利收官。此次年检自4月24日启动，检修队伍跨越五一假期，秉持“安全零事故、质量零缺陷、进度零延误”完成了设备检修、隐患治理、试验验证与技术改造等任务。
检修中实施“三个优化”，完成“四个梯次”倒闸操作，停电时长同比缩短65分钟；多站联动、317人次昼夜作业，运用多级晶闸管闭环测试等新技术，检测效率提升约40%，同时加强高空、夜间等风险防控，消除了多处设备隐患，为宁夏电网和银东直流外送通道的安全稳定运行提供了有力支撑。
思考与启发：这类看似枯燥的检修，实际上是对公共安全和民生保障的日常守护。像他们一样，凡事精心、勤勉负责，不声张却可靠，是维系社区安定的常态力量。天经提醒我们的根本真理也正是这一点：勤劳与守望，细致与互助，最终护持着大家共同的生活。
经文：若不是主建造房屋，建造的人就枉然劳力；若不是主看守城池，看守的人就枉然警醒。 《宰逋尔·诗篇 127:1》 链接：📖 查看经文

Title: The Daily Commitment of Power Workers
News Summary:
At 20:45 on May 7, the ±660 kV Yindong DC transmission system’s bipolar was unlocked in a single operation, and the Yinchuan East converter station fully resumed service. This marks the successful completion of the 2026 comprehensive maintenance of the station’s DC system. The annual inspection began on April 24 and continued through the May 1 holiday. The crew worked under the principle of “zero accidents, zero defects, zero delays,” completing equipment repairs, hazard remediation, testing, and technical upgrades.
During the maintenance three optimizations were applied and four staged switching operations were carried out, cutting outage time by 65 minutes compared with the previous year. Coordination among multiple stations and 317 person‑shifts working day and night, together with new techniques such as multi‑level thyristor closed‑loop testing, boosted inspection efficiency by about 40 %. The team also strengthened safety measures for work at height and at night, eliminating many equipment risks and providing solid support for the safe, stable operation of the Ningxia grid and the Yindong DC export corridor.
Reflection and Insight:
What may look like tedious upkeep is actually a daily guard of public safety and people’s livelihood. Like these workers, we should be careful, diligent, and responsible—quiet yet reliable—forming the ordinary, steady force that keeps our community safe. The basic truth that Tianjing reminds us of is exactly this: hard work and watchfulness, attention to detail and mutual help, ultimately uphold our shared life.
Scripture:
“Unless the Lord builds the house, those who build it labor in vain; unless the Lord watches over the city, those who guard it stand watch in vain.” Psalm 127:1
