    摘 要:現(xiàn)有換流變壓器冷卻系統(tǒng)在大負(fù)荷期間散熱能力不足,一定程度上導(dǎo)致?lián)Q流變壓器運行工況惡化,對換流變壓器的壽命產(chǎn)生不利影響。在現(xiàn)有換流變壓器冷卻方式不變的前提下,提出了一種利用水噴霧方式輔助降低換流變壓器本體和冷卻器溫升的設(shè)計方案,給出了各個輔助降溫系統(tǒng)的設(shè)計流程及換流變壓器事故油池排水量計算,并在工作現(xiàn)場取得了較好的降溫效果。該方案以現(xiàn)有換流站閥外冷水池為水源,投入較小,便于工作人員運行維護(hù),方便換流站的綜合管理,有一定的推廣價值。

    Abstract: The existing cooling system of converter transformer is insufficient in heat dissipation potential during periods of heavy load,which to some extent leads to the deterioration of the operating conditions of the converter transformer, and has a negative impact on the life of the converter transformer. Under the premise that the existing converter transformer cooling method remains unchanged, this paper proposes a design scheme that uses the water spray method to help reduce the temperature rise of converter transformer body and cooler, the design process of each auxiliary cooling system and the calculation of the displacement of oil pool in rheological accident of the converter transformer are given, and good cooling effect is achieved in the work site. The scheme uses the cold water pool outside the valve of the existing converter station as the water source, has less input, is convenient for the operation and maintenance of the staff, and is convenient for the comprehensive management of the converter station, and has certain promotion value.
    Key words: converter transformer; water spray; cooling system; dissipate heat
