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。
Application and performance
Pressure release valves play a vital role in the protection of oil-immersed electrical equipments, such as transformers, high voltage switch gears, capacitor and on load tap-changers, etc. This device can prevent the oil-immersed electrical equipment from deformation or rupture. Should a fault occur in such electrical equipment, from deformation of rupture? Should a fault occurring in such electrical equipment, they are instantaneously vaporize the oil causing extremely rapid build-up of gaseous pressure? If mounting this type pressure release device on the oil-tank, when the pressure reaches to its opening pressure, it opens automatically within 2ms and relieves the pressure.
