With the development of power industry, dry-type transformer, as a new type of transformer equipment, is widely used in various fields. The dry-type transformer has the advantages of simple structure, easy maintenance, safety and reliability, but some matters still need to be paid attention to during use to ensure its normal operation and extend its service life.

1、the installation location of the dry transformer should be installed in a well-ventilated, dry and dust-free place with appropriate temperature. Avoid direct sunlight, high temperature environment and humid areas to avoid affecting the heat dissipation and insulation performance of the transformer.

2、In the process of transportation and handling, attention should be paid to avoid violent vibration and collision, so as not to damage the internal structure of the transformer and insulation materials. Use tools to avoid accidental injuries caused by manual handling.

3、Insulation testing The insulation performance of dry transformer is the key to its normal operation. Before use, the insulation should be tested to ensure that the insulation resistance meets the requirements. Insulation resistance test should be carried out regularly to discover and deal with insulation faults in time to ensure the safe operation of the transformer.

4、Temperature control Dry transformer will generate a certain amount of heat during operation, so temperature control is required. The temperature of the transformer should be checked regularly to ensure that it does not exceed the rated temperature. If the temperature is abnormal, the fault should be removed in time to avoid affecting the normal operation of the transformer.

5、Maintenance Regular maintenance of dry type transformers is an important measure to ensure their normal operation. The transformer surface and ventilation holes should be cleaned regularly to prevent dust accumulation from affecting the heat dissipation effect. At the same time, the terminal and insulation parts of the transformer should be checked regularly to ensure that they work normally.

6、Dry-type transformers are vulnerable to lightning strikes in lightning weather, so corresponding lightning protection measures need to be taken. Devices such as lightning rods and grounding devices can be installed to protect the transformer from lightning damage.

7、Pay attention to safety in the use of dry transformer, should pay attention to safe operation. Do not stack inflammable and explosive materials around the transformer to avoid fire. To avoid personal injury and equipment damage, it is prohibited to disassemble or maintain the transformer without authorization.

As a new type of transformer equipment, dry transformer has many advantages, but in the process of use, it is still necessary to pay attention to installation location selection, transportation and handling, insulation detection, temperature control, maintenance, lightning protection measures and safe operation. Only the correct use and maintenance can ensure the normal operation and prolong the service life of the dry-type transformer.
