You have set the capacity, it depends on what material you use, whether you use copper or aluminum.

S means three-phase, it is the loss level of the transformer, 10 is smaller than the loss of type 9, 11 is smaller than the loss of 10, and the loss of 11 is about 70% of 9.

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.

S11 is the magnitude of the national standard for transformer loss copy, which is lower than the loss of S9; 10 is the rated voltage of 10 thousand volts on the high voltage side, 400 volts on the low voltage side, and 800kva is the rated capacity of 800kva. The price depends on what material you want to wind, more aluminum and less copper is much cheaper than asking all copper, and the impact is also required to answer the configuration of the protection device, insulation requirements, protection level, altitude, etc.

When the rated voltage is applied to one winding of the transformer, and the rest of the windings are open, the active power absorbed by the transformer is called no-load loss. No-load loss, also known as transformer iron loss, refers to the occurrence in the transformer core lamination, when the periodically changing magnetic field lines pass through the material, caused by the hysteresis and eddy current of the material, and its size is related to the operating voltage and tap voltage.

S11 is the magnitude of the national standard for transformer loss, which is lower than the loss of S9; 10 is the rated voltage of 10 kV on the high voltage side, 400 volts on the low voltage side, and 800kVA is the rated capacity of 800kva. **This depends on what material you want to wind, more aluminum and less copper is much cheaper than all copper, and the impact of ** is also required to configure the protective device, insulation requirements, protection level, altitude, etc.

s11 ；Indicates the power transformer.

type, S11 is a dry-type transformer, if followed by an "M" (e.g.; "S11-M"), an oil-immersed transformer.

10/ ；Represents the transformer ratio, which represents the primary input voltage of 10 kV and the secondary output voltage of kV.

800kva ；Indicates that the transformer power is 800 kVA.

The model of the transformer is usually composed of symbols that indicate the number of phases, cooling method, voltage regulation method, winding core and other materials, as well as the transformer capacity, rated voltage, and winding connection method.

You can inquire about Hedu and Hefei Yuanzhen at the market price, these two transformers are good!

**, Domestic brand, about 100,000 oil-immersed type, about 13 dry type, if it is a box change, add a box of about 70,000 for American style, and 100,000 for European basic configuration.

S11 is the device model.

10 is the rated voltage of 10 kV on the high voltage side, kV on the low voltage side, and 800kVA is the rated capacity of 800kva

Summary. What is the difference between S11M and S11 transformer "M" is the meaning of full sealing, "S11-M transformer" is a three-phase fully sealed transformer, from the appearance, there is no oil pillow on the transformer, compared with ordinary transformers, the fully sealed transformer technology has obvious advantages in terms of reliability, service life, operation and maintenance;

However, the S11 transformer is a newly developed and applied generation of transformers, and most of them are "M" type products.

What is the difference between S11M and S11 transformer.

Hello, I'm a co-teacher who asks and I'm happy to serve you.

Hello, I am inquiring for you here, please wait a while, I will reply to you immediately What is the difference between S11M and S11 transformer "M" is the meaning of full sealing, "S11-M transformer" is a three-phase fully sealed transformer, from the appearance, that is, there is no oil pillow on the transformer, compared with ordinary transformers, fully sealed transformer technology has obvious advantages in reliability, service life, operation and maintenance; However, the S11 transformer is a newly developed and applied generation of transformers, and most of them are "M" type products.

1. M is fully sealed, S11M is fully sealed transformer, no oil pillow. The S-11-M series fully sealed oil-immersed power transformer has the advantages of low loss, low noise and high efficiency, which can achieve good energy-saving effect and reduce pollution. Compared with the ordinary oil-immersed transformer, the fully sealed transformer cancels the oil conservator, and the change of oil volume is automatically adjusted and compensated by the elasticity of the corrugated oil tank bellows, and the transformer is isolated from the air to prevent and slow down the deterioration of oil and insulation aging, enhance the reliability of operation, and operate normally without maintenance.

The S11 transformer has an oil pillow.

2. Transformer is a device that uses the principle of electromagnetic induction to change the AC voltage, and the main components are the primary coil, the secondary coil and the iron core (magnetic core). The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage regulation (magnetic saturation transformer), etc.

According to the use, it can be divided into: power transformer and special transformer (electric furnace transformer, rectifier transformer, power frequency test transformer, voltage regulator, mine transformer, audio transformer, intermediate frequency transformer, high-frequency transformer, impact transformer, instrument transformer, electronic transformer, reactor, transformer, etc.). Circuit symbols often start with t.

Example: T01, T201, etc.

The performance of the oil-immersed transformer S13 is much higher than that of the S11. Among the main parameters, in addition to the load loss parameters, the no-load loss and no-load current parameters are much better than S11, and the main parameters are compared as follows

S13: Load loss 600(W);No-load loss 65(W);No-load current ;

S11: load loss 600 (W);No-load loss 100 (W);No-load current ;

The no-load current and loss of S13 transformer are lower than that of S11 transformer, but S13** is more expensive than S11, and there are more commonly used transformers in China or S10 and S11.

In terms of process and materials, S13 has been greatly improved, and in the end, it depends on the loss index of the transformer, which has been greatly reduced.
