摘要
介绍了超额定电流负载系数和时间的计算方法;探讨了500 kV变电站大型电力变压器可能出现的长期急救周期性负载运行情况;对500 kV主变压器是否允许保持运行状态进行校核判断;阐述了长期急救周期性负载运行的不利因素与解决方案。
The paper introduces the calculation about overload factor and time duration. It studies the operation condition under probable long-term periodical emergent overload of the large power transformer; checks and determines the allowance of keeping in operation for 500 kV power transformer; and thus demonstrates the unfavorable factors together with related solutions during long-term periodical overload operation.
