随着电力工业的迅速发展,电网不断扩大,电力系统主要设备之一的变压器的总容量和单台容量都有了很大增加。几年来变压器的运行情况基本是好的。但也发生了一些事故。根据1970年至1974年对电压为110千伏及以上的变压器事故的不完全统计,五年内共发生损坏事故93台次,问题是比较严重的。特别是一些高电压大容量的变压器在运行中发生事故,不仅损坏了设备,而且由于修复工期较长,对工农业生产的影响也较大。对变压器的事故应引起足够的重视。因此,必须提高变压器的制造质量和加强运行维护管理。
With the rapid development of the power industry and the expansion of the power grid, the total capacity and single capacity of the transformers, one of the major power system equipment, have greatly increased. Transformers in recent years the operation is basically good. But some accidents happened. According to the incomplete statistics on transformer accidents of 110 kV and above from 1970 to 1974, a total of 93 damage accidents occurred within five years, the problem is more serious. In particular, some high-voltage high-voltage transformers in operation accidents, not only damaged the equipment, but also because of the longer repair period, the impact on industrial and agricultural production is also greater. The transformer accident should cause enough attention. Therefore, it is necessary to improve the quality of transformer manufacturing and strengthen the operation and maintenance management.
