NarvikS13-630 power transformerRecommend Consultation

There are also many problems to pay attention to in the preventive measures and process of dry-type transformer damping. What are the key effects and functions of dry-type transformer damping and the corresponding preventive measures? Let's master and consult in detail with the small editor of the dry-type transformer manufacturer.Some are tied with plastic tape, and some immediately press the two edges together, because the socket can not be pressed firmly during installation, and there is still oil leakage without sealing effect.Narvik,At that time, only a few companies in China could produce kV high-voltage transformers, and the market share of high-voltage transformers was basically monopolized by overseas leaders.The input and output three-phase power lines shall be connected to phase a, phase B and phase C respectively according to the color of yellow, green and red bus duct of transformer terminal board. The zero line shall be connected to the neutral zero line of transformer voltage, and the grounding wire, transformer casing and its transformer point shall be connected to each other. At ordinary times, the ground wire and zero wire are led out by the neutral wire of the transformer. (for example, the transformer box shall be matched with the ground wire mark of the shell and connected with each other). Check the input and output lines to ensure they are appropriate and accurate.Chimkent,The power transformer conductor refers to the connecting transmission line between each electromagnetic coil, between the electromagnetic coil and the group outlet pipe, and between the electromagnetic coil and the tap changer.After the oil is drained, all anchor bolts of the automobile oil tank at the upper end of the detachable oil cover shall be tied with the lifting jack, and the lifting point shall be on the common earrings or bolts. If necessary,NarvikPower transformer picture, the human resources traction belt shall be used as a guide.Naturally 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.

During no-load test run,NarvikDry type transformer unit, the transformer shall be connected with the working voltage from the switching power supply side, and then make the working voltage impulse closing.Visual inspection method for transformer inspectionProtective measures for damping of dry-type transformeroriginal,When the manufacturer of the power transformer samples from the automobile oil tank after opening the sealing cover, use the cleaned and dried rubber stopper to the oil. At the same time, clamp the branch pipe with your thumb, and loosen your thumb to make the oil enter the pipe,Noise pollution control and prevention measures of dry-type transformerPower transformer manufacturer

Before and after sampling,Note: in the whole process of safety patrol inspection the on-site operation and maintenance management staff must use temperature tester or thermal imager to carry out purposeful inspection on the transformer itself, terminal block and other accessories; The sound during the operation of the transformer is a symmetrical current sound. If the sound is found to be abnormal, significantly expanded, or there is local sound,Narvik6 kV Transformer, the cause shall be found immediately and certain effective measures shall be taken. If necessary, the load can be reduced or the operation of the transformer can be stopped.Maintenance contents of power transformer& ldquo; YN, D & rdquo;, in which indicates that when the working voltage phasor of the primary side line, as the minute hand, 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).Narvik, seal the flange, and solve the bolts that are likely to leak, so as to achieve the goal of complete treatment. Tighten the loose bolts strictly according to the actual operation and processing technology.The oil in the machinery and equipment of the oil storage tank shall generally stand for more than h before sampling; it is not necessary to stand when sampling on the running power transformer.
