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.The power transformer is designed according to the temperature protection scheme. The embedded parts in the material layer of high (low) pressure electromagnetic coil poured with integral concrete are provided with longitudinal ventilation duct, which can be equipped with air-cooled machinery and equipment (cooling centrifugal fan). After selecting air-cooled machinery and equipment, the output capacity can be increased by %.South Boston,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, so as to promote the improvement of energy consumption level of transformer commodities.In relay protection dry-type transformer, the disconnection of the fault point is related to each other. In a word, if there is any problem at a certain point, it will affect the whole power circuitSaint Etienne, there are empty welding, open welding, needle holes, sand holes and other shortcomings in welding. The oil transformer is easy to be covered with welding powder and paint when leaving the factory,South Boston660V to 380V three-phase transformer, and the potential safety hazards are exposed after operation. In addition, the electromagnetic induction vibration will crack the electric welding and lead to leakage.The time difference between different steps of three-phase power switch of switching power supply shall be less than ms, and the neutral line of transformer shall be reliably grounded (it shall be grounded immediately).Fault judgment of power transformer

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,South BostonRecycling power transformer manufacturer, appropriate surface treatment shall be carried out, and then Fushi blue raw materials shall be selected for sealing treatment.Transformer isPower transformers are also used for testing, which are called test power transformers. They can be divided into inflatable, oil transformer, dry test and other test power transformers. They are the basic test equipment for communication AC compression test for many consumers such as power stations, power supply bureaus and scientific research institutions. According to the specifications of the Bureau of quality supervision, It is used to carry out insulation compressive strength test under required current for various electrical products, electrical components and insulating raw materials.High value,Power transformerThe main reason is that the welding quality of electric welding is poor, open welding, needle holes, sand holes and other shortcomings in welding. The oil transformer is easy to be covered with welding powder and paint when leaving the factory, and the potential safety hazards are exposed after operation. In addition, the electromagnetic induction vibration will crack the electric welding and lead to leakage.Wiring mode of dry-type transformer:

Power transformerPriceThere 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.The appropriate power saving calculation formula should be derived from the following process: active power loss of large capacity transformer: load of large capacity transformer; PDK - short-circuit fault loss of large capacity transformer, kW. Active power loss of small capacity transformer: when a pump room is in normal operation two pumps are started separately, and each pump is driven by kW motor, so the usual load is KW, CST = . One kva transformer was originally configured, and the capacity utilization rate introduced by the transformer manufacturer is only %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.South Boston,Protective measures for damping of dry-type transformerDue to careless transportation of the transformer and the thin high-voltage conductor, the transformer was disconnected by vibration (but there was no grounding device).Plug in the power with full load first, observe and detect that the input and output voltage meets the regulations. At the same time,South BostonTypes of dry-type transformers, check whether the equipment has abnormal sound ignition, odor and other abnormal conditions. If there is any abnormality, please cut off the input switching power supply.
