Walker MattModel and parameters of power transformerWhat's the development prospect now

During no-load test run,Walker MattModel and specification of power transformer, the transformer shall be connected with the working voltage from the switching power supply side, and then make the working voltage impulse closing.Noise dispersion of dry-type transformerWalker Matt, it is necessary to carry out voltage transformation and blood pressure reduction according to the transformer to reduce the loss of electromagnetic energy in the whole process. Therefore, the power consumption of the processing plant is all connected with kV switching power supply, which is converted into bottom voltage electromagnetic energy through transformer.Deterioration damage of transformer core insulationIreland,When the transformer is out of phase, if the second phase is blocked, there is still no sound when the second phase is sent, and there is sound when the third phase is sent; If the third phase is blocked, the sound will not change, as in the case of the second phase. There are three reasons for phase deficiency: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.& 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).

The vibration reduction solution of cable bridge is to modify the hard connection between bus bridge and dry-type transformer, and the vibration reduction solution is made at the cable bridge.This is the example of power consumption engineering as power saving. The key reason is that the habitual calculation method ignores the copper loss.The insulating layer in the middle of the silicon steel plate is aging, the anchor bolt cover with the iron core is damaged, the iron core causes large vortex resulting in heat, temperature rise, and the aging of the insulating layer is accelerated. The core insulation compressive strength of power transformer must be measured on time and accurately. If it is found that the insulation compressive strength is less than the index value, please remove and replace the anchor bolt cover or carry out insulation for the copper core cable.Quality documents,Oil immersed transformer operationThen clamp the branch pipe with your thumb, clearly put forward the glass test tube, rotate and release the oil in the tube to clean the sampling tube, carry out it twice, and then draw the oil sample.When oil samples are used,Avoid the load operation of power transformer: if the load operation is long-term,Walker MattHow much is a 160 power transformer, it will lead to the scalding of solenoid coil, slow aging of insulation short circuit fault between boxes, the flange plate, barrel skin and the middle of the waterproof sleeve at the upper end of the automobile oil tank. The internal iron core and winding clamp are hot due to partial magnetic leakage, resulting in insulation damage.A 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.Walker Matt,Manufacturing process and steps of dry-type transformerWhen leaving the factory, the production and processing are not smooth and the sealing is poor. The common fault of oil leakage will be caused after the oil transformer is sealed for a period of time.During 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.
