Oil immersed transformerTherefore in the installation process of substation equipment, in the installation and use process of lightning rod, during the installation of lightning rod, please connect all routes as far as possible to prevent other faults.Luca,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,LucaPower transformer oil immersed, 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.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.Mchinji,High voltage fuse of transformer breaks one phase;The flange surface is uneven, the tightening bolts are loose, and the installation and processing process is wrong, so that the bolts are not tightened well, resulting in oil leakage.When the full load test is carried out and everything is normal, the load can be connected.

Before and after sampling, clean the periphery of the sampling port with clean or hairless linen.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.When the power transformer operates at full load, it needs a large reactive load. This reactive load shall be provided by the power supply and distribution system. If the transformer volume is too large, but also make the transformer operate at full load or load for a long time, expand the proportion of full load loss, reduce power factor and increase Internet loss. Such operation is neither economic development nor scientific.Job description,Oil leakage of porcelain pot and laminated glass oil level gaugeOil immersed transformer operationWhen the manufacturer of the power transformer samples from the automobile oil tank, after opening the sealing cover,LucaModel and meaning of oil immersed transformer, 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,

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.Quality improvementAnalysis of common faults of oil immersed transformer:How to maintain dry-type transformer?After no-load test run is normal for h,LucaEnergy efficiency class I oil immersed transformer, it can be transferred to on-load operation, and the load shall be gradually increased from %, % and % by grade.Luca,It will also produce many faults, effectively deal with various faults of oil immersed transformer, make full use of the performance indicators and advantages of oil immersed transformer, and continuously improve the safety factor of oil immersed transformer. Ignition is a common fault of oil immersed transformer. The key fault of oil immersed transformer is short-circuit fault, and short-circuit fault is more general.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, weather conditions and other materials of the oil sample.The method and whole process of taking oil sample of power transformer are as follows:
