压 力 释 放 阀PRESSURE RELEASE VALVE使用说明书OPERATION INSTRUCTION明远电器设备SHENYANG MINGYUAN ELECTRIC EQUIPMENT CO., Ltd.本说明书适用于我公司生产的系列变压器用压力释放阀，阐述其用途、性能、规格、技术参数、使用与安装，供用户参考。The Operation Instruction is applicable to pressure release valve of a series of transformers manufactured by our company, indicating its application, performances, specifications, technical parameters, usage and installation for uses’ 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、电力电容器与有载分接开关等，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 迅速动作，释放压力，保护油箱不致变形或爆裂。油箱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，变压器部不会受大气污染。1. Application and performance Pressure release valves play avital 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.2．型号、规格与基本参数 Type,specification and technical parameters 2.1 型号的含义 Meaning of typeY S F□—□ / □□□特别环境代号（Special environment）带机械信号标“J”（“J”：mechanical signal）带信号开关标“K...
