On load commissioning:The noise of dry-type transformer is mainly the vibration noise in operation. This vibration noise is caused by multiple positions, including the vibration of magnetic induction electromagnetic coil. All pay great attention to the solution of vibration when carrying out noise control.Birkikara,Under normal conditions, different oil-based oils cannot be mixed. Under special circumstances, if it is necessary to use new oil of different grades, it should be determined whether the mixed oil with ice degree can be used according to the requirements of the region and then the oil mixing test should be carried out.Analysis of common faults of oil immersed transformer:Mbaiki,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.A specific part of dry-type transformer is the hanging core of dry-type transformer. The hanging core of dry-type transformer is a vital component. How to carry out the hanging core?Brief introduction of zero line of power 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.In fact, apart from the application of the Finance Bureau, the industry has been trying to formulate and upgrade transformer commodities according to the specifications,Birkikara1250KW dry type transformer, so as to promote the improvement of energy consumption level of transformer commodities.Avoid the load operation of power transformer: if the load operation is long-term, it will lead to the scalding of solenoid coil, slow aging of insulation, short circuit fault between boxes, two-color short circuit fault or short circuit to ground fault and dissolution of oil.For more, please check,From the appearance, the packaging types are different. The transformer core and electromagnetic coil can be seen immediately for dry-type transformer, and only the shell can be seen for oil immersed transformer;Due to careless transportation of the transformer and the thin high-voltage conductor, the transformer was disconnected by vibration (but there was no grounding device).The clock expression is used to indicate the phase difference correlation of the working voltage of the secondary side line. The phasor of the working voltage of the primary side line is used as the minute hand, the fixed finger is at o'clock, and the phasor of the phase voltage of the secondary side is used as the second hand.

Falling foreign matters and piercingOnline consultation, the calculation of data in the whole process of oil immersed transformer wave has long had results. Only effective selection of calculation entity models and methods is needed,BirkikaraDistribution transformer wiring group, the accuracy of calculation conclusions can meet the needs of architectural design, and scientific and reasonable data method is selected,BirkikaraPower transformer customization, Not only can the current distribution of the oil immersed transformer be clearly defined in the development stage, but also the winding and other structures of the oil immersed transformer can be effectively arranged and distributed in a certain scope, which greatly facilitates the design scheme of the oil immersed transformer and ensures the stability of operation.The insulation of the through core anchor bolt clamping the iron core is damaged, resulting in a short circuit fault between the silicon steel sheet of the iron core and the through core anchor bolt;Turn off the gate valve (butterfly valve) of the left and right tablet computers of the heat pipe radiator to isolate the oil in the heat pipe radiator from the oil in the tank, so as to reduce the working pressure and leakage. After the leakage location is determined, appropriate surface treatment shall be carried out, and then Fushi blue raw materials shall be selected for sealing treatment.Birkikara,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.In order to better reduce the probability of short-circuit fault of relay protection dry-type transformer
