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,MadrugaSupply of power transformer, weather conditions and other materials of the oil sample.The key reason for oil leakage is that there are defects in cast iron partsMadruga, drilling stop hole is a good way to remove in-situ stress and prevent widening.Soroca,Power transformerThere are many connection groups of dry-type transformers, and the selected structures and connections are also different. Then, what are the groups of dry-type transformers? How to carry out the connection? Or basically introduce it with the network of dry-type transformer manufacturers.In the electric field of the winding to the yoke, there must be a strong line breaking component so that sliding flash charge and discharge may occur at a lower current. In order to better solve this disadvantage, the appearance of the insulating parts between the winding and the iron yoke should be the same as that of the medium horizontal plane of the winding to the iron yoke insulation as far as possible, so as to reduce the electric field component intersecting with the insulating parts.

The power transformer is composed of two or more electromagnetic coils wound around the same transformer core. The winding resistance is connected according to the alternating electromagnetic field and works according to the basic principle of magnetic effect of current. The installation position of power transformer shall be considered to be conducive to operation, maintenance and transportation, and a reliable area shall be selected at the same time. The rated capacity of the transformer must be effectively used when applying the transformer.Transformer inspection nose sniffing methodDuring no-load test run, the transformer shall be connected with the working voltage from the switching power supply side, and then make the working voltage impulse closing.average method,Solenoid insulation deteriorationThe capacity and working voltage are different. The dry-type transformer is generally suitable for distribution equipment. The capacity is generally below kVA and the working voltage is below KV, which also ensures the rated voltage of kV; Oil immersed transformers are generally suitable for distribution equipment.Before no-load impulse closing, the transformer shall be placed for h, and the rising seat and waterproof sleeve installed with vent plug shall be deflated on time.

The noise of dry-type transformer comes fromFor more, please check,The hanging core of dry-type transformer is a vital partThe 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, the market has not yet fully operated.Manufacturing process and steps of dry-type transformerMadruga,In specific daily life,MadrugaCharacteristics of dry type distribution transformer, we have a certain understanding of the optical wavelength of oil immersed transformer. What kind of function does it have for transformer?Some are tied with plastic tape, and some immediately press the two edges together,MadrugaHow much is 2500 dry-type transformer, because the socket can not be pressed firmly during installation and there is still oil leakage without sealing effect.Sound, causing short circuit obstruction. If not handled properly, it will cause great damage.
