    摘 要:壓力釋放閥作為油浸式電力變壓器的泄壓防爆裝置,是非電量保護(hù)系統(tǒng)中的關(guān)鍵設(shè)備之一。梳理了壓力釋放閥裝置試驗(yàn)分類,分析了其關(guān)鍵性能參數(shù),針對性能試驗(yàn)中存在的試驗(yàn)標(biāo)準(zhǔn)滯后、檢測設(shè)備復(fù)雜且缺乏規(guī)范、例行試驗(yàn)不合格率偏高、開啟時間檢測難以實(shí)施、排量性能試驗(yàn)不完善等若干問題,進(jìn)行了具體的原因分析及難點(diǎn)解剖,并提出了相應(yīng)的處理措施及合理化建議。
    關(guān)鍵詞: 變壓器;壓力釋放閥;性能試驗(yàn);開啟壓力;開啟時間

    Abstract: As a pressure relief and explosion prevention device of oil-immersed power transformer, the pressure relief valve is one of the key equipment in non-electric protection system. This paper sorted out the test classification of pressure relief valve device and analyzed its key performance parameters, the specific reasons and difficulties were analyzed for the problems existing in the test, such as the hysteresis of test standard, the complex testing equipment without unified technical specifications, the high unqualified rate of routine tests, the difficult implementation of the open time test, and the imperfect displacement performance test. Finally, this paper put forward the corresponding measures and rationalization suggestions.
    Key words: transformer; pressure relief valve; performance test; operating pressure; open time
