本厂生产的变压器用压力释放阀完全执行行业标准 JB7065-2004Me Factory production of transformers with pressure release valve to fully implement the industry standard JB7065-2004该压力释放阀适用于变压器、电力电容器、有载开关、压力容器罐等,用来保护油箱和容器罐。 The pressure release valve for transformers, power capacitors, load switches, pressure vessel tanks and so on, used to protect the fuel tanks and tank containers. , 如何选用压力释放阀?how to Selected pressure release valve ? a 、喷油口径的选用 Selection of Spray oil -caliber : 油箱内油量(Oil mass of oil box)1.5T 1.5T 4.5T 4.5T 11.5T 11.5T 23T 阀有效口径(Effective -caliber of valve): ∮25 50 80 130 如果油量超过 23T 可按下式选择:If the oil can be pressed more than 23T Selection 130 口径压力释放阀的数量 = 总油量重量 T / 23T 130 caliber pressure release valve number = total weight of oil T / 23T b 、压力释放阀开启压力的选择 Pressure release valve opening pressure of the choice开启压力等级的选择决定于关闭压力的大小,关闭压力 PG 按下式计算: The choice of opening pressure level determined by the size of the pressure off, close the pressure of PG determined by the formula: PG = PH + PK + PQ 其中 Thereinto PH = 压力释放阀承受静压值 Pressure release valve to withstand static pressure values ( V×H ) KPa V 是指变压器油柱压 Refers to the transformer oil column pressure 89 KPa / m H 是指最高油面至阀座底面的距离 Refers to the maximum of oil to the distance from the bottom seat(m) PK 是附加的安全裕度压力,一般取 Is an additional margin of safety, the general public to take 5 7 KPa PQ 是附加的强油、风冷裕度压力,一般取 There is an additional strong oil, air-cooled margin, the general public to take 5 7 KPa 求得关闭压力 PG , 通过下表(基本技术参数)可知道开启压力值 PG obtained after the closure of the pressure, by the following table (basic technical parameters) can be aware of the


YSF 代表压力释放阀, 5 代表设计序号, 55 代表开启压力, 130 代表有效口径,
