Cooling oil tank of high-voltage pulse power electronic equipment

The utility model belongs to the technical field of high-voltage pulse power electronic equipment, and relates to a cooling oil tank of high-voltage pulse power electronic equipment. A pressure relief component (2) is arranged at the bottom of the oil tank body (1), a component shell (9) of the pressure relief component (2) is connected to the bottom of the oil tank body (1) and communicated with the oil tank body (1), and a pressure relief bag (10) is arranged at the position, close to the upper portion, in the component shell (9) and is of a structure made of high-temperature-resistant flexible materials. According to the cooling oil tank for the high-voltage pulse power electronic equipment, the creepage or sparking risk caused by high-voltage exposure due to the fact that the liquid level is lowered when the temperature of insulating oil in the oil tank body is lowered can be avoided; the problems that when the temperature of insulating oil in the oil tank body rises, the insulating oil expands to cause s
