摘要
针对公司两台220 kV变电站站用变压器在一台变压器检修时,另一台变压器带站内所有负荷时,就会出现过负荷,变压器温度升高等现象,本文提出了采用更换变压器和增加无功补偿装置两种方案,通过两种方案对比,最终采用增加无功补偿装置方案,实施后,获得了较好的效果。
When one transformer for 200 kA substation is under repair, the other one will bear all the loads of substation, it will lead to excess load and increasing transformer temperature. For these problems, this paper proposes changing transformer and adding reactive power compensating device, by contrast of two schemes, the later one was adopted and realized better effects in production.
