In specific daily life， we have a certain understanding of the optical wavelength of oil immersed transformer. What kind of function does it have for transformer?
& ldquo; of wiring transformer; Enter & rdquo; And & ldquo; Output & rdquo; Use a megger to test the grounding resistance between the terminal and the ground wire. When accurately measured by V megger the resistance value exceeds m ohm bus.
AkabadiWith Vietnam and Malaysia， China"s first UHV transmission experimental demonstration project， China Transformer Corporation has entered a breakthrough in the development trend. The commodity voltage grade and volume rank first in the world， occupying the main technical position of the industry development trend. In addition， it has promoted the continuous improvement and perfection of the technology of low-voltage transformers.
During no-load test run， the fixed finger is at o"clock and then make the working voltage impulse closing.
KurumeThe 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， and the phasor of the phase voltage of the secondary side is used as the second hand.
The noise of dry-type transformer belongs to low-frequency noise. In a small area， 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， and then causes gas vibration noise， 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.
After the test connect the data signal contact of the automobile relay with the alarm circuit， the pull-in contact with the opening circuit， and adjust the overcurrent protection value.
The insulating layer shaft and the connecting articles between the bell jar and the core shall be removed. If it is a hanging bell inspection， the high-capacity transformer must be replaced by the small-capacity transformer with high utilization rate， and then the iron loss is considered and the copper loss is ignored. In fact， for a certain load， the active power loss of small capacity exceeds that of large capacity The active power loss of the transformer， so it consumes electromagnetic energy.
Oil leakage of heat pipe radiator
production costsIn the case of dry-type transformer operation， there is more noise， and some even cause noise， which seriously endangers everyone"s no problem rest time and work. At this time， the dry-type transformer needs sound insulation treatment. There are many processes and key methods to deal with the noise of the common dry-type transformer. How should the noise of the dry-type transformer be solved? Or with the dry-type transformer manufacturer"s network editor to simply understand it.
With the rapid development of society and the continuous development trend of computers， 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， the accuracy of calculation conclusions can meet the needs of architectural design， 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.
The raw materials of Fushi blue can be used for bonding， so that the overall oil leakage of the connector can be greatly controlled; If the actual operation is convenient， the metal shell can also be bonded at the same time to achieve the purpose of leakage treatment.
In specific daily life，AkabadiDry type transformer 125kva，AkabadiMain transformer of wind farm， oil immersed transformers are released outward in the form of waves. This kind of wave is like a tide. It is also a kind of kinetic energy. In fact， the wave height of oil immersed transformer also shows the size of kinetic energy. Generally， computer automatic system is used to control the wavelength and frequency of electromagnetic wave. The longer the light wavelength is， the greater the output power is. On the contrary， it is very small.
Finance DepartmentNaturally， if the oil immersed transformer catches fire， please don"t panic. I firmly believe that the damage will be reduced to a lower level as long as the above methods are effectively rectified. Above is the general process and process that should be paid special attention to in the whole ignition process of the oil immersed transformer. When the oil immersed transformer catches fire， please be rational to make the oil immersed transformer safer and more efficient.
The appropriate power saving calculation formula should be derived from the following process: active power loss of large capacity transformer: load of large capacity transformer; PDK - short-circuit fault loss of large capacity transformer， kW. Active power loss of small capacity transformer: when a pump room is in normal operation，AkabadiAmorphous alloy oil immersed transformer， two pumps are started separately， and each pump is driven by kW motor， so the usual load is KW， CST = . One kva transformer was originally configured， and the capacity utilization rate introduced by the transformer manufacturer is only %

& ldquo; YN， D & rdquo;， in which indicates that when the working voltage phasor of the primary side line， as the minute hand， refers to the position at o"clock， the phase voltage phasor of the secondary side is at o"clock. That is， the phase voltage UAB of the secondary side lags degrees behind the working voltage uab of the primary side line (or degrees ahead).
