Bhairawa Pricethe purchase price of dry-type transformer is much higher than that of oil immersed transformer.
When the whole process of winding wave of oil immersed transformer is calculated by using the marking method, and each module is replaced by an equivalent circuit, and its power circuit includes an inductance and vertical capacitance, a capacitance to ground or capacitance between windings, They also have mutual inductors between the inductors of each module, and collect the chain Internet as the equivalent power circuit of oil immersed transformer. The precision of the conclusion can completely meet the needs of practical projects.

Dry type transformer
.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.
Method and process of taking oil sample of power transformer
In specific daily life, 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.
The no-load impulse closing working voltage shall not exceed 5% of the working voltage marked on the gear of the transformer, the closing frequency shall be 5 times, the delay time after power receiving shall not be less than 10min, and the time interval of each closing shall not be less than 5min.
The transformer manufacturer shall not use hand touch method to detect energized high-voltage equipment, such as transformer in operation and neutral grounding equipment of arc suppression coil. For the equipment without power supply and whose shell is reliable grounding device, the temperature or temperature rise must be tested by hand. The secondary equipment can be inspected by hand touch method when it is hot and vibrated.
Use fiber materials to seal the bolts to achieve the goal of controlling leakage. The other is to screw out the bolt (nut) wipe the Fushi blue film remover on the surface,Lesbridge80 box type transformer, and then tighten it after wiping the raw materials on the surface. After drying,LesbridgePower transformer 2, the treatment goal can be achieved.
Convenient and efficient.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.

Fault judgment of power transformer
Before application, 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, and then cleaned with purified water for many times. The cleaned sampling container shall be dried in a 105 ℃ drying oven. After refrigeration, the bottle cap shall be tightly closed and cannot be opened before application.
Development Curriculum.If the power transformer stops running for more than 72h (if the allowable time should be reduced when the ambient humidity is & amp; gt; 95%), it should be insulated before putting into use, and accurately measured with a 2500V grounding megger. The insulation resistance from the primary side to the secondary side and the ground should be ^ 300mfl, the insulation resistance from the secondary side to the ground should be ^ 100mh, and the insulation resistance from the iron core to the ground should be & amp; gt; 5mfl (note that the grounding device piece should be removed).
The secondary inductive equipment of the distribution station (such as transformer, voltage transformer,LesbridgeWhat is the price of 1000 KVA transformer, automobile relay, AC, etc.) operates normally. According to the AC current, the winding transformer core will send out a symmetrical rhythm and a certain tone & ldquo; Buzz, buzz & rdquo; Sound. The operation staff of the transformer manufacturer should understand and grasp the characteristics of the noise. When the equipment has common faults, there will be noise and even & ldquo; Crackle & rdquo; The charging and discharging sound can distinguish the generation and characteristics of common equipment faults according to the music law and sound transformation when everything is normal and abnormal.
