2、atingitsapplication,performances,specifications,technicalparameters,usageandinstallationforuses’reference.1.压力释放阀用途和性能压力释放阀适用于油浸式电力变压器、电力电容器及有载分接开关等,用来保护油箱。当油浸式变压器在运行中出现故障时,由于线圈过热,使一部分变压器油汽化,变压器油箱中压力迅速增加,这时压力释放阀在2ms内迅速动作,释放压力,保护油箱不致变形或爆裂。油箱内的压力再升高而达到开启压力时,压力释放阀应再次动作,直到
3、油箱内的压力降到正常值。由于压力释放阀动作后能可靠关闭,油箱外的水和空气不能进入油箱,变压器内部不会受大气污染。1.ApplicationandperformancePressurereleasevalvesplayavitalroleintheprotectionofoil-immersedelectricalequipments,suchastransformers,highvoltageswitchgears,capacitorandonloadtap-changers,etc.Thisdevicecanpreventtheo
