MahendranagaHoPetrelaHow much is the transformer,
The iron core of power transformer is made of high-quality crystallized hot-rolled ferrite core which is stacked at the 45 degree fully inclined multi-step interface. The surface is covered with epoxy resin adhesive cable sheath coating, which is resistant to corrosion and rust, and has sound insulation and noise reduction.

The noise of dry-type transformer is mainly the vibration noise in operation. This vibration noise is caused by multiple positions, including the vibration of magnetic induction electromagnetic coil. All pay great attention to the solution of vibration when carrying out noise control.
Power transformers are used in all walks of life
The technical specification of power consumption requires that the resistance of maintenance grounding wire shall be ≤ 4Ω, The resistor is generally more than 2000 & omega;, According to Ohm's law, when the insulating layer is damaged, the current is only 1 / 500 of the total current flow, so as to play a guarantee effect. The higher the voltage, the smaller the resistance, in other words, the calculation of data in the whole process of oil immersed transformer wave has long had results. Only effective selection of calculation entity models and methods is needed a group of overvoltage maintenance high-voltage Arresters (such as y4cs active zinc oxide high-voltage arresters) shall be refitted at the working voltage bus duct side of dry-type transformer.
With the rapid development of society and the continuous development trend of computers, the accuracy of calculation conclusions can meet the needs of architectural design, and scientific and reasonable data method is selected Not only can the current distribution of the oil immersed transformer be clearly defined in the development stage, but also the winding and other structures of the oil immersed transformer can be effectively arranged and distributed in a certain scope, which greatly facilitates the design scheme of the oil immersed transformer and ensures the stability of operation.
consumption.The method and whole process of taking oil sample of power transformer are as follows:
The first step of the whole wave process calculation is to calculate the basic parameters of the Internet such as inductance, capacitance and resistor. The accuracy of those basic parameters does great harm to the calculation results of the whole wave process. For the inductance calculation, but there are many calculation methods.
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.
Then clamp the branch pipe with your thumb, clearly put forward the glass test tube, rotate and release the oil in the tube to clean the sampling tube, carry out it twice, and then draw the oil sample.

Power saving analysis of transformers has always been based on whether the utilization rate of transformer capacity is less than a certain standard value. Whether transformers are environmental protection and energy saving specifications. In fact, sometimes such specifications are not saving electromagnetic energy, but consuming electromagnetic energy.
When sampling from a small and medium-sized power transformer without a discharge pipe (or oil sample suspension plate), it can be in a power transformer such as a glass test tube when it is not in operation to extract the oil sample at the bottom, or it can be replaced by changing the oil.
Petrela.Before application,PetrelaProcurement of dry type transformers, the sampling container shall be cleaned with vehicle gasoline, soapy water or other organic solvents (such as trisodium phosphate) except oil stains, and then washed with tap water until it is not alkaline, and the water can be evenly distributed from the bottle, the bottle cap shall be tightly closed and cannot be opened before application.
After tightening the loose bolts, seal the flange, and solve the bolts that are likely to leak,PetrelaStandard for power frequency withstand voltage test of dry type transformer, so as to achieve the goal of complete treatment. Tighten the loose bolts strictly according to the actual operation and processing technology.
Dry 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 0.2%, and then reduce the building structure noise transmitted by dry-type transformer oscillation.
