In relay protection dry-type transformer， the disconnection of the fault point is related to each other. In a word， if there is any problem at a certain point， it will affect the whole power circuit
MaldacanThe person in charge of a transformer manufacturer said that because of the hazards of raw materials and other factors， the cost of energy-saving transformers is significantly higher than that of traditional transformers， and the price factor is also a key factor endangering the popularization and marketing of energy-saving transformers. Although there are energy-saving and convenient subsidy projects to help energy-saving transformers， the market has not yet fully operated.
The switching power supply lacks one phase of power;
Christian SanAvoid inadvertent damage of insulation during maintenance: when repairing the hanging core of power transformer， special attention shall be paid to the maintenance of solenoid coil or insulating waterproof sleeve. If there is scratch damage，MaldacanPower transformer M， it shall be handled properly.

The clock expression is used to indicate the phase difference correlation of the working voltage of the secondary side line. The phasor of the working voltage of the primary side line is used as the minute hand the fixed finger is at o"clock， and the phasor of the phase voltage of the secondary side is used as the second hand.
Equipped with a temperature controller， platinum thermistor (pt) is placed beside the embedded hole on the top of the low-voltage solenoid coil to test the winding resistance temperature rise of the transformer， stop the cooling centrifugal fan， set up common problem alarm， and provide reliable overvoltage protection machinery and equipment for the dry test transformer， so as to test the safety performance of the transformer operation.
The insulation between silicon steel sheets is damaged， resulting in overheating and melting of the iron core;

Equipped with a temperature controller platinum thermistor (pt) is placed beside the embedded hole on the top of the low-voltage solenoid coil to test the winding resistance temperature rise of the transformer， stop the cooling centrifugal fan， set up common problem alarm， overtemperature alarm and overtemperature tripping effect， and provide reliable overvoltage protection machinery and equipment for the dry test transformer， so as to test the safety performance of the transformer operation.
Due to poor sealing， generally， the sealing of box edge and machine cover is sealed with acid-base resistant rubber rod or rubber plate. If the joint is not solved well， it will lead to common faults of oil leakage.

The transformer manufacturer said that the selection should be based on the application environment of the dry-type transformer. For the extremely extreme environment， the dry-type transformer should be poured with epoxy resin glue. Because this kind of environment does not need to heat the dry-type transformer， it can operate immediately. However， for the general application environment， the class H dry-type transformer can be used.

In the whole process of transmitting electromagnetic energy in the power supply system， it will inevitably cause the loss of voltage and output power. When transporting the same output power， the voltage loss is inversely proportional to the voltage， and the output power loss is inversely proportional to the square meter of voltage. The transformer is used to increase the voltage and reduce the closing damage.
