石河子干式变压器：石河子干式变压器油箱机械强度及升高油压试验

石河子干式变压器油箱机械强度及升高油压试验 　　
油箱机械强度试验仅在不装有器身的单独油箱上进行.它是将油箱充满油，并用压力机(有的厂用水压机代替)加压0.1MPa，测量油箱外形尺寸。解除压力后，再进行测量.要求无残留永久变形或永久变形不得超过油箱壁厚的两倍(不包括箱盖)，所有焊接部分也不应有损伤和开裂，供装配和密封部分均保持正常，则认为试品机械强度试验合格。如在有关标准或产品技术条件中规定，需施加部分真空，则要求解除真空后箱盖等不发生凹陷才合格。

Tank mechanical strength and increased hydraulic test

Tank mechanical strength test in a separate tank equipped with a body only, it is a tank full of oil, and the press (and some plant presses instead of water) pressure 0.1MPa, measuring tank Dimensions. Relieves stress, and then measured. Requires twice the residual permanent deformation or permanent deformation shall not exceed the tank wall thickness (not including the cover), all welded part is not due damage and cracking, for the assembly and sealing parts to maintain normal that the mechanical strength of the test product test qualified. Such provisions in the relevant standards or product technical conditions required to impose a partial vacuum, they are required to l华盈非晶合金变压器有限公司ift the cover such as vacuum after the occurrence of depression qualified.
