SantaremUnit price of box type transformerHow to promote industrialization quickly

The sampling container is a colorless glass bottle with a wide mouth ground glass plug with a volume of .kg or kg. - bottles shall be collected at a time for analysis and experiment. Labels shall be attached during sampling. Pay attention to the name, source, sampling date, sampling person, weather conditions and other materials of the oil sample.Caused by sand holes and cracks. For crack leakage, drilling stop hole is a good way to remove in-situ stress and prevent widening.Santarem,Precautions for trial operation of power transformer manufacturersIf 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,SantaremHigh voltage bushing of oil immersed transformer, 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,SantaremModel of 35kV dry type transformer, 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,Power transformer is an idealized supporting facility transformer for medium cabinet and high-voltage cabinet at the present stage and rotate the crane to place the bell cover on the clean skid.Beyla, and can be equipped with safety protective casing according to different waterproof grades. It is applicable to key or unique natural environment sites such as multi-storey buildings, commerce, airports, tunnel construction, chemical enterprises and factories.The bearing capacity of each load is different. Generally, dry-type transformer should operate under rated capacity, while oil transformer has better load working capacity.In order to better carry out the experiment of power transformer oil, it is necessary to sample the power transformer oil. The sampling work should be carried out on a dry sunny day. The commonly used containers and sampling methods during sampling do immediate harm to whether the specific quality of the oil can be truly reflected. The oil sample for AC voltage withstand test shall not be less than .kg,SantaremPerformance of dry type transformer, and the oil sample for simplified experiment shall not be less than kg.

Power transformers are used in all walks of lifeThe transformer manufacturer will introduce the efficiency of the transformer to youDry type transformer factoryOK or not?, the power transformer will be transported and sent to the power consuming machines and equipment. What is the zero line of the actual power transformer? Let's introduce it to us.Common problems of tap changer of power transformerThe flange surface is uneven, and the installation and processing process is wrong, so that the bolts are not tightened well, resulting in oil leakage.

The voltage regulating tap changer is not in place or poorreform,The heat discharge pipe of heat pipe radiator is generally made of slotted seamless steel pipe after flattening by stamping die. When the heat discharge pipe is bent and welded by electric welding, oil leakage is often caused. This is due to the supporting force on the surface of the pipe and the working pressure on the inner cavity when stamping the heat discharge pipe.When the operating oil is mixed with different types of new oil or used for oil, in addition to the accurate measurement of the cold filter point of the mixed oil, it is also necessary to carry out high and low temperature test and sludge test, and observe the sludge accumulation. The accumulation cannot be accessed. The results of the operation of the mixing template are not that the original oil is very poor, so it can be managed and used in a mixed manner.Before no-load impact closing, the pose period of overcurrent protection shall be set to zero, and the data signal circuit of steam vehicle relay shall be temporarily connected to the pull-in circuit.Santarem,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.According to the condition of cracks, galvanized iron wire can be punched into the leakage or riveted with hammer. Then clean the leakage point with toluene and seal it with raw materials. Coated sand casting eyes can be sealed with raw materials immediately.The representative mode of connection group of dry-type transformer is: English capital letters indicate the wiring on the primary side (or primary side), and English letters indicate the wiring on the secondary side (or secondary side). Y (or y) is star wiring
