A dry-type transformer is a transformer that does not require oil cooling.
It has the following precautions during operation:
1. Temperature control: Temperature control is the key to dry-type transformers. Excessive temperature may cause damage to the transformer. Therefore, the temperature of the transformer should be tested regularly to ensure that it always operates within a safe range.
2. Insulation inspection: conduct routine inspections on the insulation of dry-type transformers to ensure that the insulation materials are not aging or damaged. Good insulation conditions can ensure the normal operation of the transformer and avoid other safety hazards such as electric shock.
3. Maintenance: Regularly carry out daily maintenance work such as cleaning, tightening bolts, and lubricating dry-type transformers. This not only prolongs the life of the transformer, but also reduces the risk of failure and damage.
4. Environmental conditions: The dry-type transformer should be placed in a well-ventilated and dry environment.
Avoid direct contact with water or wet items to prevent short circuits and other failures.
5. Overload protection: When using a dry-type transformer, care should be taken not to make its load exceed the rated value. Overloading may cause the transformer to overheat, damage it, and even cause a fire in severe cases. When it is necessary to use a current that exceeds the rated load, a transformer with a larger capacity should be considered at this time.
6. Regular inspection: Regular inspection of the current, voltage, temperature and other indicators of the dry-type transformer.
If any abnormality is found, it should be repaired or replaced in time.
