A transformer uses the principle of electromagnetic induction to change the AC voltage, and the main components are the primary coil, the secondary coil and the core (core).
The main functions of the transformer: voltage conversion, current conversion, impedance.
Transversion, virtual isolation, voltage regulation (magnetic saturation transformer) and other transformers.
According to the use, it can be divided into: distribution transformer, fully sealed transformer, combined transformer, dry-type variable code voltage, oil-immersed transformer, single-phase transformer, electric furnace transformer, rectifier transformer, etc.
The transformer converts the AC voltage and alternating current.
and impedance of the device, when the primary coil is passed.
When there is an alternating current, an alternating current is generated in the iron core (or core).
Causes a voltage (or current) to be induced in the secondary coil.
The transformer is composed of an iron core (or magnetic core) and a coil, the coil has two or more windings of Xunlu, of which the winding connected to the power supply is called the primary coil, and the rest of the windings are called secondary coils.

Anonymous users2024-01-31Summary. Hello dear! Thank you for your patience, according to the information given in the title, the rated capacity of the S10-40000 type 10 transformer is 40000 kVA, and the conversion ratio is 10, that is, the ratio of input voltage to output voltage is 10:
1。The calculation of the weight of a transformer requires consideration of several factors, including the material and size of the transformer's core, coils, and other components, as well as additional equipment and oil levels. According to the provisions of the national standard GB T 6451-2015 "Technical Conditions for Transformers", the relative quality coefficient of S10-40000 type 10 transformer is, that is, the weight of the transformer is several times of its rated capacity.
Therefore, the weight of the S10-40000 Type 10 transformer is about 138 tons (40000 .
How many tons does the s10-40000 10 transformer weigh.
Hello dear! Thank you for your patience, according to the information given by the topic, the rated capacity of S10-40000 10 transformer is 40000 kVA, and the conversion ratio is 10, that is, the ratio of input voltage to output voltage is 10:1.
The calculation of the weight of a transformer requires consideration of several factors, including the material and size of the transformer's core, coils, and other components, as well as additional equipment and oil levels. According to the provisions of the national standard GB T 6451-2015 "Technical Conditions for Transformers", the relative quality of S10-40000 type 10 transformer is a combination factor, that is, the weight of the transformer is several times of its rated capacity. Therefore, the weight of the S10-40000 Type 10 transformer is about 138 tons (40000 .
Generally speaking, the larger the conversion ratio, the more material and weight are required for components such as cores and coils of a transformer. At the same time, the larger the capacity of the transformer, the greater the number of wires and windings required to wind the coil, thus increasing its weight. 2.
In addition to the weight of the transformer itself, it also needs to consider factors such as its additional equipment and oil volume. For example, the cooling system of the transformer, the disconnecting switch, the control equipment, etc., will increase its weight. The density of transformer oil is generally around 850 900 kilograms per cubic meter.
Therefore, the amount of oil in the transformer also has an impact on its total weight. 3.The weight of the transformer is a problem that needs special attention during its transportation, transportation, transmission and installation.
Due to the large size and heavy weight of the transformer, special equipment and measures are required for lifting and transportation to ensure its safety and reliability.
When the primary winding of the transformer is energized, the magnetic flux generated by the coil flows in the iron core, because the iron core itself is also a conductor, and the electric potential will be induced in the plane perpendicular to the magnetic field lines, and this electric potential will form a closed loop on the section of the iron core and generate a current, as if p a vortex is called "eddy current". This "eddy current" increases the loss of the transformer and increases the temperature rise of the transformer's core heating transformer. The loss caused by "eddy currents" is called "iron loss". >>>More
The easiest way is to buy a ready-made control transformer, dismantle the secondary stage, and remember how many turns are used for how much voltage when dismantling, so that you can calculate how many turns the 5000V voltage should be around. If there are no special requirements, it can be made in the form of an autotransformer, so that the problems of interlayer insulation and lead wires can be simplified when designing the transformer. If there is an isolation requirement, between the primary and secondary pads around 3 layers of barley paper, and then around the secondary, pay attention to the enameled wire must be densely wound neatly, do not cross, do not go around to the very edge of the transformer skeleton, so as to prevent the coil from discharging the core, wrap a layer of pad around a layer of insulating paper, and wrap the outermost layer of 3 layers of insulating paper after winding, and then pre-dry, when the transformer wire package is not cool, soak in the prepared insulating paint, the insulating paint can not be too viscous, thin and easy to soak, Dry and then assemble the core. >>>More

To choose a 150kva transformer.
In line with the principle of "small capacity, dense distribution point", the distribution transformer should be located in the load center as far as possible, and the power supply radius should not exceed one kilometer. The load factor of the distribution transformer is the most efficient between, and the capacity of the transformer at this time is called the economic capacity. However, if the load is relatively stable, the transformer capacity can be selected according to the economic capacity in the case of continuous production. >>>More
