Why do electric furnace transformers leak oil?
Yixing Xingyi Special Transformer Co., Ltd. was founded in 1992. The company covers an area of 68,000 square meters, including 45,000 square meters of standard workshops. There are 360 employees, including 2 professor-level special transformer experts and 18 professional transformer designers. There are 15 manufacturing process control personnel, 22 quality control personnel, and 260 front-line production personnel. The main products are various electric furnace transformers with a single capacity of 110KV and below, and a single capacity of 50000KVA, rectifier transformers, magnetic voltage regulators, special transformers, power transformers, wind power transformers Power generation, photovoltaic power substations, reactors, etc.
The oil leakage of the electric furnace transformer is the main problem of the transformer. The oil leakage of the electric furnace transformer will not only affect the normal use of the transformer, but also bring hidden dangers, stop the operation of the electric furnace transformer, and even seriously damage the transformer, which seriously affects the normal operation of the transformer. Common electric furnace transformer oil leakage has the following phenomena:
1) Oil leakage at the link flange. The reason for this phenomenon is mainly due to the incorrect installation of the rubber gasket at the joint.
2) Oil leaks from the oil sampling valve or the vent plug. This is mainly due to the frequent use of these parts, which can easily lead to oil leakage.
3) There is oil leakage between the oil chamber of the on-load switch and the oil chamber of the transformer body. This is mainly because the large sealing flange of the oil chamber of the on-load tap-changer is not tightly sealed, which leads to the oil chamber of the on-load switch. The acetylene in the main body diffuses into the oil chamber of the main body, causing the transformer oil acetylene in the main body to exceed the specification.
