Today's first-class dry-type transformer is primarily equipment that relies on air convection to cool. Therefore, it has good heat dissipation performance and excellent environmental applicability. Thus, a simple dry-type transformer is universally introduced into every corner of people's lives with its unique advantages. Then, how do users maintain a high-quality and reliable dry-type transformer to extend its service life? The details are as follows:
First: pay attention to the iron core inspection
Users should pay attention to the use of clean compressed air and oxygen to purge the core of the equipment, the surface of the clamp and the gaps in order to effectively remove foreign matter in the dry type transformer
configuration with excellent effect. In addition, the user should also pay attention to carefully check the clamps of the equipment, the pull bolts, the clamp bolts and the core screw for looseness. If the core and the surface coating of the clip are damaged, the user needs to repair with the same color paint in time.
Second: pay attention to the maintenance of the coil
Users should pay attention to regularly investigate whether the weather-resistant dry type transformer lead insulation is intact, with or without deformation, brittleness, and lead-free strands. In addition, the user should pay attention to the test of the dry transformer lead and joints for overheating and lead connectors can be reliable. When the user finds that the insulation of the coil is deformed and becomes brittle, it needs to be replaced in time.
Third: pay attention to electrical connections
According to the research, the user has a certain contact pressure in the electrical connection during the operation of the reliable dry-type transformer to ensure the good electrical conductivity of the equipment. Moreover, the user should carefully check the effective connection between the low-voltage lead-out line of the dry-type transformer and the connecting busbar, the high-voltage terminal and the high-voltage cable connection nose.
Of course, in addition to the above problems that users need to pay attention to when using dry-type transformers, users also need to carefully check whether all equipped fans can be turned on and off at the same time. Moreover, the recommended transformers for reactor manufacturers can’t be separated from the time of manufacture to the start of operation for a long time to avoid the insulation of the equipment and the subsequent use effect.
