monterey How mPower transformer is one of the key equipment in power station and substation. The function of power transformer is in all aspects. It can not only raise the voltage and send electromagnetic energy to the power consumption area, but also reduce the voltage to each application voltage, so as to meet the needs of power consumption. In short, voltage transformation and blood pressure reduction must be carried out by the transformer.
The tap changer of power transformer shall also have strong insulation. 10kV off load tap changer is generally insulated from the ground by the produced insulating paper pipe factory.
Monterivano.The common dry-type transformer is an important electrical equipment, and the voltage is constantly regulated. However, because of certain necessity, and the whole process of boosting voltage is very complex, and there are many principles.
The scientific research of power transformer oil is generally carried out according to the way of sampling. What are the common sampling methods and processes?
.Different diversion methods,MonterivanoS13-50 power transformer, dry-type transformers mostly use silica gel waterproof casing while oil transformers mostly use porcelain waterproof casing;
The no-load impulse closing working voltage shall not exceed 5% of the working voltage marked on the gear of the transformer, the delay time after power receiving shall not be less than 10min the closing frequency shall be 5 times, and the time interval of each closing shall not be less than 5min.
What about oil immersed transformer fire?
The vibration reduction solution of cable bridge is to modify the hard connection between bus bridge and dry-type transformer, and the vibration reduction solution is made at the cable bridge.
Protection mode for type selection of dry-type test transformer
Therefore, in the installation process of substation equipment, the lightning rod should be set according to the specific situation to prevent damage to the relay protection dry-type transformer caused by lightning. In addition, in the installation and use process of lightning rod, select reasonable types of lightning rod according to the operation situation to determine that they are in the same situation. In addition, during the installation of lightning rod, please connect all routes as far as possible to prevent other faults.
Product line.Equipped with a temperature controller, platinum thermistor (pt10) 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.
Avoid aging and damage of power transformer iron core insulation: aging of iron core insulation or damage of waterproof sleeve holding anchor bolt will cause large vortex of iron core, and long-term scalding of iron core will lead to insulation aging.
After the oil is drained all anchor bolts of the automobile oil tank at the upper end of the detachable oil cover shall be tied with the lifting jack, and the lifting point shall be on the common earrings or bolts. If necessary, the human resources traction belt shall be used as a guide.
Manufacturing process and steps of dry-type transformer
Where can I find it?.Method and process of taking oil sample of power transformer
The 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.
It is generally made due to unreasonable installation or ineffective sealing. Polymer composite materials can bond metal materials, laminated glass and other materials very well, so as to achieve the pressure management of oil leakage.
Monterivano.The cross-sectional wiring of transformer input and output power plugs shall comply with the provisions of their current size; It should be equipped according to the current intensity of 2-5A / Min2.
If the volume of power transformer is too small, the transformer will be overloaded for a long time and it is easy to destroy machinery and equipment. Therefore, the rated capacity of the transformer should be selected according to the power consumption, which is not suitable for too large or too small.
The noise of dry-type transformer belongs to low-frequency noise. In a small area,Monterivano800 box type transformer,MonterivanoTransformer distribution room, most of it is scattered according to the building structure. This kind of low-frequency noise is scattered to the household house according to the house building, which is then scattered to the ears of consumers. Although the amount of noise is not very large, the dispersion spacing and adverse effects are very large.
