Daily inspections to check whether the state of the closed oil-immersed transformer is good. Whether the results of the preventive test are normal. For large transformers.Detect whether the system of the copper winding transformer has a short circuit faul
the correct maintenance method is crucial for the operating life of outdoor copper winding oil filled distribution transformers. It is easy to cause damage to the individual components of the oil filled transformer during the overhaul process, resulting
For complex and variable outdoor environments, a three-phase oil-immersed outdoor transformer is the main choice because of its low cost and easy maintenance.
Once the oil immersed transformer has failed, it can be said that it has a huge impact on production, life and safe use of electricity. Therefore, it is very important to make an accurate judgment on the faults of the three-phase transformer and to elimin
They only know the amorphous alloy oil-immersed step-down transformer and the three-phase dry 500kva transformer.
The dry series iron core reactor is one of the main components of the shunt capacitor device. It acts as a limiting capacitor combination shunt current, suppresses power harmonics, prevents damage to the capacitor, and avoids excessive amplification of th
Transformer manufacturers want to get more orders, it is necessary to proceed from its quality and price, and constantly adjust the cheap three-phase dry-type transformer. For the transformer, it should improve its quality from the following four aspects
The reliability and service life of the motor winding operation depend to a large extent on the properties of the insulating material.
Oil-immersed transformers often have various problems during normal operation. What should be done when faced with these abnormal operation conditions can reduce the loss.
Hermetically Sealed Oil Filled Transformer:
Operating conditions of distribution transformers:
l. The voltage applied to the transformer should not exceed 105% of the corresponding tap (switch) voltage. The maximum load should not exceed the rated capacity of the transformer.
In order to ensure the normal use of dry power transformers, it is necessary to detect various aspects of the transformer and find problems in time to solve the problem.
When the overload capacity of the dry transformer is stronger, the overload time will be longer.
Therefore, the oil filled transformer is tested within the specified time, the test is passed, the transformer oil continues to be used, and if it is unqualified, the oil is changed.
In order to make the oil filled transformer work more smoothly, improve efficiency and be environmentally friendly. Therefore, oil-immersed transformers began to use environmentally friendly transformer oil.
