So the transformer casing collapse? _ transformer skeleton has some insight and understanding.
(10)济南变压器http://www.jnwdsh.com滚揉机变压器外表、套管及检修场地是否清洁。（ 017 ）变压器在检修后复役送电前的准备 检查油位、油温、油色有无变化；（ 3 ）检查防爆管是否破裂喷油；（ 4 ）检查变压器外壳有无变形 它可作为变压器高压绕组引出线，母线接地短路的
(10) whether the roller, the transformer, the outer surface, the casing and the inspection site are clean. (017) in the maintenance service after the transformer power supply before checking the oil level, oil temperature, oil has no change; (3) check whether the explosion tube rupture injection; (4) check the transformer shell without deformation which can be used as the high voltage winding of the transformer lead wire, bus grounding short circuit
(四)渗漏油 渗漏油是变压器常见的缺陷，渗与漏仅是程度上的区别，渗漏油常见的部位及原因有：环氧地坪 1.阀门系统，蝶阀胶材质安装不良，放油阀精度不高，螺纹处渗漏。 2.胶垫接线桩头，高压套管基座流出线桩头，胶垫较不密封、无弹性，小瓷瓶破裂
(four) the oil leakage of transformer oil leakage is a common defect, seepage and leakage is only a difference in degree, position and causes of oil leakage are common: epoxy floor 1. valve system, butterfly valve rubber material poor installation, oil discharge valve thread leakage accuracy is not high. 2. cushion pile head connection, high voltage bushing base line out of the pile head, the rubber pad is not sealed, no elasticity, small porcelain rupture
