In large and medium-sized transformers, the pressure releaser is generally arranged on an oil tank of the transformer, and when the transformer works normally, the oil of the transformer is protected from the outside air. When the transformer is short-circuited, the transformer winding generates electric arcs and sparks, so that a large amount of gas is instantly generated by transformer oil, the pressure in the oil tank is increased greatly, when the pressure reaches a set pressure, the pressure releaser is opened and releases the pressure, and the pressure releaser is automatically closed after the pressure is released. Therefore, the transformer oil tank is prevented from being deformed and exploded due to overlarge pressure. At present, in a transformer manufacturing process, before a pressure releaser is installed, the reliable action of the pressure releaser must be checked, and the prior art has no special pressure releaser checking device, so that the reliable action of the pressure releaser is very inconvenient to check, and the quality of a transformer product is possibly influenced.
