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?In the case of using dry-type transformer,New MumbaiModel of power dry-type transformer, customers must master the method of wiring. If there are problems in wiring, it is easy to cause common faults in application. So, what is the wiring mode of dry-type transformer?New Mumbai,Overtemperature alarm and trip: collect winding or iron core temperature data signals according to the temperature measurement resistor of PTC discrete system thermistor embedded in the bottom voltage winding. When the transformer winding temperature rises again, if it reaches ℃, the system software outputs the overtemperature alarm system; If the temperature rises to ℃ again and the transformer can no longer operate the overtemperature trip data signal must be transported to the secondary maintenance circuit,Dry type transformer oscillation is solved by applying vibration damping platform to dry-type transformer and carrying out low-frequency vibration reduction management, which can control the oscillation below .%, and then reduce the building structure noise transmitted by dry-type transformer oscillation.The heat discharge pipe of heat pipe radiator is generally made of slotted seamless steel pipe after flattening by stamping die. When the heat discharge pipe is bent and welded by electric welding, oil leakage is often caused. This is due to the supporting force on the surface of the pipe and the working pressure on the inner cavity when stamping the heat discharge pipe.Operation and maintenance management of oil immersed transformer

Method and process of taking oil sample of power transformerPower transformer is indispensable for power stations and substations, but we must pay attention to many problems in the whole process of applying power transformer.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.Quality improvement,The main reason is that the welding quality of electric welding is poor, there are empty welding, open welding, needle holes, and the potential safety hazards are exposed after operation. In addition, the electromagnetic induction vibration will crack the electric welding and lead to leakage.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:There 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.

On load commissioning:install,Power transformer manufacturerIt should be said that after the development trend of these years, the overall level of China's transformer industry at this stage is basically international,New MumbaiHow much is a 50 KVA box transformer, and the quality level is no different from that of overseas goods& rdquo; The person in charge of the transformer Federation of China Household Appliance Industry Association said.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.New Mumbai,The technical specification of power consumption requires that the resistance of maintenance grounding wire shall be ≤ Ω, According to Ohm's law, when the insulating layer is damaged, the current is only / of the total current flow,New MumbaiPrice of dry type 800kVA transformer, so as to play a guarantee effect. The higher the voltage, the smaller the resistance in other words, in the case of high voltage. We can care about the power transformer plant and master a lot of professional knowledge.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.Avoid inadvertent damage of insulation during maintenance: when repairing the hanging core of power transformer special attention shall be paid to the maintenance of solenoid coil or insulating waterproof sleeve. If there is scratch damage, it shall be handled properly.
