The utility model discloses a pressure relief valve of a transformer. The device comprises a marking rod arranged on a pressure releaser, a metal indicating piece is arranged at the end, away from thepressure releaser, of the marking rod, a proximity switch used for sensing the change of the distance between the pressure releaser and the metal indicating piece is arranged on the pressure releaser, and the proximity switch is electrically connected with a tripping loop. The pressure relief valve has the advantages that a microswitch is changed into the metal proximity switch, so that equipmentdetection is more visual, accessories are more convenient to replace, and the pressure relief valve is not affected by environmental factors. 本实用新型公开了一种变压器压力释放阀，包括设置在压力释放器上的标志杆，所述标志杆远离压力释放器的一端设置有金属指示件，所述压力释放器上设置有用以感知与金属体指示件间距变化的接近开关，所述接近开关与跳闸回路电连接。本实用新型具有以下有益效果：这种压力释放阀将微动开关改为金属接近开关，使设备检测更为直观，更换配件更为便捷且不受环境因素影响。
