Noise solution of dry-type transformerWhen leaving the factory,SanzakatHow much is a 160 box transformer, the production and processing are not smooth and the sealing is poor. The common fault of oil leakage will be caused after the oil transformer is sealed for a period of time.Sanzakat,Several detection methods for installing transformerThe tap changer of power transformer shall also have strong insulation. kV off load tap changer is generally insulated from the ground by the produced insulating paper pipe factory.Boke,For the installation of lightning rod, it is very easy to damage the relay protection inside and outside of dry-type transformer by lightning. If it is a serious situation, damage to machinery and equipment power failure, etc.In order to better reduce the probability of short-circuit fault of relay protection dry-type transformer, prevention and key are & ldquo; Prevention and Manipulation & rdquo; Is dominant.Oil leakage of heat pipe radiator
Solenoid insulation deteriorationProtection mode for type selection of dry-type test transformerDry type transformer oscillation is solved by applying vibration damping platform to dry-type transformer and carrying out low-frequency vibration reduction management, which can control the oscillation below .%, and then reduce the building structure noise transmitted by dry-type transformer oscillation.Welcome calls Gradually, high-frequency vibration damping mechanical equipment, such as low-frequency vibration damping platform, is installed at the bottom of the dry-type transformer, which can reduce the downward dispersion of the vibration of the dry-type transformer. Then replace the connection between the dry-type transformer and the surrounding engineering buildings, roads, etc. with flexible connection, the dry-type transformer room can also be soundproofed and decorated, and sound-absorbing plates and silencing shutters can be used to improve the soundproofing capacity of the dry-type transformer room.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,SanzakatDry type transformer scb10-100, 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.Solenoid insulation deterioration
The input and output three-phase power lines shall be connected to phase a, phase B and phase C respectively according to the color of yellow, green and red bus duct of transformer terminal board. The zero line shall be connected to the neutral zero line of transformer voltage, and the grounding wire, the transformer box shall be matched with the ground wire mark of the shell and connected with each other). Check the input and output lines to ensure they are appropriate and accurate.Superior quality the ground wire and zero wire are led out by the neutral wire of the transformer. (for example,Sanzakat500 kV dry type transformer,Noise solution of dry-type transformerTwo point grounding device of iron core caused by residual welding scar;If you want to check the activated carbon fiber for the hanging cover, first take out the low-voltage waterproof sleeve and the on load transformer power switch, then lower the bell cover anchor bolt of the large cover, slowly hang the galvanized steel wire rope with sufficient lifting net weight on the commonly used earrings, wear round steel from top to bottom in the surrounding screw holes, and count the spacing and specifications for easy reinstallation. At the same time, the cable wind shall be added on all sides to ensure that the core international body will not be damaged during the whole lifting process. After lifting for mm, stop the lifting, stabilize the bell cover, and check the bearing capacity of the lifting core, center of gravity and Jack. After everything is normal, lift it again until the bell cover exceeds the relative height of the body, and rotate the crane to place the bell cover on the clean skid.Sanzakat,The key reason for oil leakage is that there are defects in cast iron partsThe power transformer is designed according to the temperature protection scheme. The embedded parts in the material layer of high (low) pressure electromagnetic coil poured with integral concrete are provided with longitudinal ventilation duct, which can be equipped with air-cooled machinery and equipment (cooling centrifugal fan). After selecting air-cooled machinery and equipment, the output capacity can be increased by %.A specific part of dry-type transformer is the hanging core of dry-type transformer. The hanging core of dry-type transformer is a vital component. How to carry out the hanging core?
