Dry type test transformer is mainly rely on air convection cooling equipment. Therefore, it has good heat dissipation performance and good environmental usability. Simple dry transformer with its unique advantages has been widely introduced into every corner of people's life, so how to maintain high quality and reliable dry transformer to extend its service life?
First: pay attention to iron core inspection
We should pay attention to the use of clean compressed air and oxygen blowing equipment core, fixture surface and clearance, in order to effectively remove foreign bodies in the equipment. In addition, the user should also pay attention to carefully check the fixture of the equipment, tension bolts, fixed bolts and internal screw is loose, if the core of the clip and the surface coating is damaged, the user needs to repair with the same color paint in time
Two: pay attention to the maintenance of the coil
Users should pay attention to regular inspection of weather resistance dry transformer lead must be intact, there is no deformation, brittle and leadfree lines in addition, users should pay attention to dry transformer lead and overheating joint test, lead connector is reliable, when the user found that the insulation layer of the coil deformation open brittle, need to be replaced in time
Third: Pay attention to electrical connections
According to the study, during reliable dry transformer operation, the user has a certain contact pressure in the electrical connection to ensure good electrical conductivity of the equipment. In addition, the user should carefully check the effective connection between the low-voltage outlet line of the dry transformer and the connecting busbar, the high-voltage terminal and the high-voltage cable terminal.
Of course, in addition to the above problems that users need to pay attention to when using dry transformers, users also need to carefully check whether all equipped fans can be turned on and off at the same time.
