Three precautions for dry power transformer maintenance

For modern people, transformers are indispensable modern equipment, because of its oil-free, flame retardant, low operating loss, and good resilience. Transformer manufacturers stressed that if the transformer is damaged, the impact on the national economy and people's lives is enormous. Therefore, caring for equipment and ensuring normal power supply is always a concern, so it is necessary to maintain it. Specifically, the maintenance of dry Power Transformers has three main considerations.

First, pay attention to cleaning and maintenance

It is necessary to do a good inspection on a daily basis, especially in an environment with harsh environmental conditions and dusty conditions. During the inspection process, the transformer manufacturer should clean up the dust and pay special attention to the presence or absence of dust in the important event. The transformer manufacturer recommends that the air duct and surface dust be blown off with a compressed air compressor of no more than 2 atmospheres. Transformer manufacturers also reminded not to touch any part of the device by hand, because it is connected to the entire power system, so take measures to prevent electric shock.

Second, pay attention to the maintenance of the load operation

The load monitoring dry power transformer has strong overload capability and can tolerate short-time overload. However, the transformer manufacturer reminds that the product is not infinitely overloaded. There are limitations in this respect, such as depending on the ambient temperature and start. The load is different, so it cannot be generalized. It should be controlled in this regard. Transformer manufacturers should ensure that the relevant system automatic tripping and alarming functions do not have any problems, and can be operated at any time. At the same time, attention should be paid to the winding and core temperature not exceeding the specified range, and the overload state should pay close attention to all aspects. Changes, should not damage the insulation due to excessive temperature rise, can not resume operation.

Third, pay attention to regular experiments and maintenance

Transformer manufacturers remind the dry power transformers of the periodic test cycle dry power transformer maintenance is generally 3 to 5 years, and should be checked once a year or longer. Transformer manufacturers introduced in other occasions, such as air that may be contaminated by dust or chemical smog, every quarter or half a year to do an in-depth inspection and maintenance, while running for several years, it is necessary to test the insulation resistance to determine the transformer Can you continue to run?

The above are the three precautions for the maintenance of dry power transformers introduced by transformer manufacturers. In addition, pay attention to whether the key parts are firm and loose, as well as rust and carbonization. In order to do this kind of processing work, the transformer manufacturer also reminded that before operation, it should also check whether the grounding system is intact to ensure safety.
