压 力 释 放 阀 PRESSURE RELEASE VALVE 使 用 说 明 书 OPERATION INSTRUCTION 沈阳明远电器设备有限公司 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、使用及安装，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. 2． 型号、规格及基本参数 Type, specification and technical parameters 2.1 型号的含义 Meaning of type Y S F □ — □ / □ □ □ 特殊环境代号（Special environment） 带机械信号标“J”（“J”：mechanical signal） 带信号开关标“K”（“K”：electrical signal） 两者都带标“KJ”（“KJ”：Both with signal） 喷油有效口径（Caliber of oil-gushing tube）mm 开启压力（Opening pressure）kPa 设计序号（Design serial number） 阀（valve） 释放（release） 压力（pressure） 注：特殊环境代号 note: special environment: TA: 干热带地区 dry tropic TH: 湿热带地区 humid tropic T: 干、湿热带地区 dry、humid tropic 例：YSF16-55/130KKJT开启压力为55kPa，喷油口径为φ130mm，带电信号、机械信号。适用于干、湿热带地区的压力释放阀。 Example: YSF16-55/130KKJT in which, opening pressure is 55kPa, caliber
