HestarMaximum temperature of oil immersed transformerExecutive agency

Avoid inadvertent damage of insulation during maintenance: when repairing the hanging core of power transformer, it shall be handled properly.Brief introduction of zero line of power transformerHestar,How to make up oil for oil immersed transformer?Wiring mode of dry-type transformer:Aksarai,Oil immersed transformer operationWhat is the important role of power transformerThe 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.

What about oil immersed transformer fire?Transformer inspection earIn the case of dry-type transformer operation, there is more noise, and some even cause noise, which seriously endangers everyone's no problem rest time and work. At this time,HestarMaintenance items of oil immersed transformer, the dry-type transformer needs sound insulation treatment. There are many processes and key methods to deal with the noise of the common dry-type transformer. How should the noise of the dry-type transformer be solved? Or with the dry-type transformer manufacturer's network editor to simply understand it.Inspection standard,(IV) the transformer on the column shall be stable and firm, and the waist rail shall be & phi; mm galvanized wire shall be wound over turns in an even number. The iron wire shall not have a connector and shall be tightened after winding. The distance between the waist rail and the energized part shall not be less than .m.Note: in the whole process of safety patrol inspection, terminal block and other accessories; The sound during the operation of the transformer is a symmetrical current sound. If the sound is found to be abnormal, significantly expanded,HestarManufacturer of 80 KVA dry type transformer,HestarProspect of distribution transformer, or there is local sound, the cause shall be found immediately and certain effective measures shall be taken. If necessary, the load can be reduced or the operation of the transformer can be stopped.When the manufacturer of the power transformer samples from the automobile oil tank, after opening the sealing cover, 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,

The first step of the whole wave process calculation is to calculate the basic parameters of the Internet such as inductance, capacitance and resistor. The accuracy of those basic parameters does great harm to the calculation results of the whole wave process. For the inductance calculation, the good model is the solid model of infinite transformer core column, but there are many calculation methods.Equipment maintenance,The power transformer belongs to relatively durable electrical equipment, and we can't neglect it in daily application. The common problems of power transformer conductor, power transformer winding and power transformer tapping power switch are analyzed below:At rated power the ratio of output power to input power of transformer is called the efficiency of transformer, i.e. & ETA; Is the efficiency of the transformer; P is the input power and P is the output power.The long-term overload of power transformer will slowly cause the scalding and insulation aging of solenoid coil, resulting in short circuit between coils, two-color short circuit or short circuit on the ground, resulting in the ignition of power transformer. Therefore, the insulation compressive strength of power transformer shall be tested before installation and operation, and overload is not allowed in the whole process of operation.Hestar,Loose core screwAfter 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.The noise of dry-type transformer comes from
