VladivostokMaintenance specification for box type transformerCan you work at height

Sound, causing short circuit obstruction. If not handled properly, it will cause great damage.After hours of continuous trial operation with a certain load, and the transformer will turn to all normal operation.Vladivostok,Transformer manufacturerWhen 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.Mytilini, 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,VladivostokDry type transformer scb10-100, 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).Oil immersed transformerThe key reason for oil leakage is that there are defects in cast iron parts

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, 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.The fundamental reason for this kind of inaccuracy is that when the transformer & ldquo; Dalar trolley & rdquo; is considered according to the size of capacity utilization rate the ground wire and zero wire are led out by the neutral wire of the transformer. (for example, the high-capacity transformer must be replaced by the small-capacity transformer with high utilization rate, and then the iron loss is considered and the copper loss is ignored. In fact, for a certain load, the active power loss of small capacity exceeds that of large capacity The active power loss of the transformer, so it consumes electromagnetic energy.Then clamp the branch pipe with your thumb,VladivostokOil immersed regulator, 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.Total quality assurance,How to reduce the failure of dry-type transformer?(III) dry type transformers of KVA and below can be installed on poles. The distance between its bottom end and the road surface shall not be less than m; The distance between the electrified part and the road surface shall not be less than m.Before and after sampling, clean the periphery of the sampling port with clean or hairless linen.

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.Test method,VladivostokVarious models of transformer,After the test connect the data signal contact of the automobile relay with the alarm circuit, the pull-in contact with the opening circuit, and adjust the overcurrent protection value.First of all, although dry-type transformer has strong moisture resistance, it is generally open structure or very susceptible to moisture, especially the insulation level of dry-type transformer manufactured in China is low (lower flame retardant grade) Therefore, the dry-type transformer can obtain high stability only when the air humidity is below %. The dry-type transformer shall also be prevented from stopping operation for a long time to prevent serious damp. When the grounding resistance value is less than / V (operating voltage), it indicates that the transformer is seriously damp, and the trial operation shall be terminated.After no-load test run is normal for h, it can be transferred to on-load operation, and the load shall be gradually increased from %, % and % by grade.Vladivostok,When the new oil filled by the power transformer and the oil sample that has just been considered are used, the oil sample can be used only after sufficient standing.Power transformer is an idealized supporting facility transformer for medium cabinet and high-voltage cabinet at the present stage, and can be equipped with safety protective casing according to different waterproof grades. It is applicable to key or unique natural environment sites such as multi-storey buildings, commerce, airports, tunnel construction, chemical enterprises and factories.In specific daily life, we have a certain understanding of the optical wavelength of oil immersed transformer. What kind of function does it have for transformer?
