Dry-type test transformers mainly rely on air convection cooling equipment. Therefore, it has good heat dissipation performance and good environmental usability. Simple dry-type transformers are widely introduced into every corner of people’s lives with their unique advantages. So, how do users maintain high-quality and reliable dry-type transformers to extend their service life? The details are as follows:

? Dry-type test transformer

First: Pay attention to the core inspection

When using it, everyone should pay attention to using clean compressed air and oxygen to purge the core of the equipment, the surface and gap of the fixture to effectively remove foreign objects in the equipment. In addition, the user should also pay attention to carefully check the fixtures, tightening bolts, fixing bolts and inner screws for looseness. If the core and surface coating of the clamp are damaged, the user needs to repair it with the same color paint in time.

Second: Pay attention to the maintenance of the coil

The user should pay attention to regularly check whether the lead of the weather-resistant dry-type transformer is intact, whether there is any deformation, brittleness, and lead-free lines. In addition, the user should pay attention to test the dry transformer leads and overheated joints, and whether the lead connector is reliable. When it is found that the insulation layer of the coil is deformed and becomes brittle, it needs to be replaced in time

?Third: Pay attention to electrical connections

According to research, during the operation of a reliable dry-type transformer, 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 lead wire of the dry-type transformer and the connection bus bar, the high-voltage terminal and the high-voltage cable terminal.

?Of course, in addition to the above-mentioned 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.
