If the above provisions are not met, the problem of dryness shall be solved. Generally, it must be eliminated to ensure indoor ventilation and avoid insulation penetration. In particular, pay attention to cleaning the insulators of the power transformer and the top and bottom ends of winding resistance installation. Portable centrifugal fan or dry air compression or N shall be used to clean the dust in indoor space that is not easy to reach, such as ventilation duct,For oil transformer oil replenishment, unused transformer oil conforming to the new standard should be selected first. In addition, the oil with the same basic, same brand and same additive type is expected to have a stronger effect. The characteristics of the oil should not be lower than that of the oil in mechanical equipment. When the new remaining oil is less than %, there is generally no problem. However, if there is more new remaining oil, oil shall be added before oil type Chromatographic analysis and pressure test shall be carried out to establish that there is no oil stain, and the acid value and dielectric loss shall not exceed the oil in the machinery and equipment.& 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).Nandaime,Manufacturing process and steps of dry-type transformerNoise pollution control and prevention measures of dry-type transformerProtective measures for damping of dry-type transformer


Curva Transformer power transmissionA few tips to improve efficiency



Dry type transformerHand touch method for transformer inspectionWhen the new oil filled by the power transformer and the oil sample that has just been considered are used,Curva 25kV power transformer,Curva Box transformer 630kVA price, the oil sample can be used only after sufficient standing.reform,Brief introduction of zero line of power transformerA zero line of the power transformer is connected with the working equipment. Since the voltage formed by the server during operation will be sent to the power transformer along with the cable, the power transformer will be transported and sent to the power consuming machines and equipment. What is the zero line of the actual power transformer? Let's introduce it to us.Sound, causing short circuit obstruction. If not handled properly, it will cause great damage.

The tap changer of power transformer shall also have strong insulation. kV off load tap changer is generally insulated from the ground by the produced insulating paper pipe factory.Word of mouth recommendation,The plastic shells of electrical products and office supplies are equipped with grounding wires. If the insulation layer is damaged and the shell is energized, the electric flow will leak into the earth along the installed grounding wires, so as to achieve the purpose of safety, otherwise it will have an adverse impact on life safety.The efficiency of transformer is closely related to the output power level of transformer. Generally, the greater the output power, the smaller the loss to output power ratio and the higher the efficiency. On the contrary the smaller the output power, the lower the efficiency.The long-term overload of power transformer will slowly cause the scalding and insulation aging of solenoid coil, resulting in short circuit between coils two-color short circuit or short circuit on the ground, resulting in the ignition of power transformer. Therefore, the insulation compressive strength of power transformer shall be tested before installation and operation, and overload is not allowed in the whole process of operation.Curva , there are empty welding, open welding, needle holes, sand holes and other shortcomings in welding. The oil transformer is easy to be covered with welding powder and paint when leaving the factory, and the potential safety hazards are exposed after operation. In addition, the electromagnetic induction vibration will crack the electric welding and lead to leakage.If you want to check the activated carbon fiber for the hanging cover, first take out the low-voltage waterproof sleeve and the on load transformer power switch, then lower the bell cover anchor bolt of the large cover, slowly hang the galvanized steel wire rope with sufficient lifting net weight on the commonly used earrings, wear round steel from top to bottom in the surrounding screw holes, and count the spacing and specifications for easy reinstallation. At the same time, the cable wind shall be added on all sides to ensure that the core international body will not be damaged during the whole lifting process. After lifting for mm, stabilize the bell cover, and check the bearing capacity of the lifting core, center of gravity and Jack. After everything is normal, lift it again until the bell cover exceeds the relative height of the body, and rotate the crane to place the bell cover on the clean skid.If the power transformer stops running for more than h (if the allowable time should be reduced when the ambient humidity is & amp; gt; %), it should be insulated before putting into use, and accurately measured with a V grounding megger. The insulation resistance from the primary side to the secondary side and the ground should be ^ mfl, the insulation resistance from the secondary side to the ground should be ^ mh, and the insulation resistance from the iron core to the ground should be & amp; gt; mfl (note that the grounding device piece should be removed).
