我厂3～6千伏高压电动机共有8台,其启动全部使用老式油断路器人工操作。在启动过程中,电弧经常会把动、静主触头烧坏,造成接触不良,不但检修频繁,工作量大,而且操作笨重。我们学习了兄弟单位的先进经验,并结合生产实际情况,大搞技术革新,试制成3～6千伏、250安高压油浸启动器,代替老式手动操作的油断路器。经过几年来使用表明,操作简单方便,运行可靠,检修周期延长,为实现自动控 I plant 3 to 6 kV high-voltage motors a total of eight units, which start using all the old oil circuit breakers manual operation. During the start-up process, the arc often burns the movable contact and the static contact, resulting in poor contact. Not only frequent maintenance, heavy workload but also heavy and bulky operation are required. We learned the advanced experience of our brother units and tried our best to make innovations based on the actual situation in production. We tried out a 3 ~ 6 kV, 250 A high-pressure oil-immersed starter to replace the old-fashioned manual operated oil circuit breakers. After several years of use shows that the operation is simple and convenient, reliable operation, extended maintenance cycle, in order to achieve automatic control
