在生产中,有些设备是不允许停电的,因其一旦停电将会造成巨大的损失,因此,许多单位都有自备的柴油发电机作为备用电源。但由于管理不严,工人操作时粗心大意常将切换开关投错,出现发电机向变压器倒送电的现象,严重时将烧坏发电设备。甚至危及检修工人的生命。我厂曾多次出现类似掌故。后来我们自己设计了一个如图所示的备 Some equipment in production does not allow power outage because it will cause huge losses in the event of a power outage. As a result, many units have their own diesel generators as backup power supplies. However, due to poor management, workers often careless care switch will switch the wrong vote, the emergence of the phenomenon of the generator back to the transformer power transmission, in serious cases will burn power generation equipment. Even endanger the life of overhaul workers. I have repeatedly appeared on similar occasions. Later, we designed ourselves as shown in the preparation
