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-gushi
