If you talk about transformer loss, then you can tell you that transformer loss is variable loss. Loss is divided into copper loss and iron loss. In order to facilitate the calculation of iron loss, it is generally a fixed value, which can be obtained according to the model and capacity of the transformer.
Copper loss is calculated at 15/1000 of the monthly electricity amount. Of course, this loss fee is only charged for the special transformer (special transformer), if the property right belongs to the power sector, and it is a transformer (public transformer) for residential use, this fee is not charged.
Generally speaking, the 50kva special transformer adopts the high supply and low meter metering method, and the metering device will not be installed far away from the transformer, so there should be no line loss in the low voltage. If the 10kV line specially erected due to the user's special transformer exceeds a certain length, the power department will calculate the line loss according to the line length and line diameter, and the charge for this part of the loss should be reflected in the power supply contract.

Generally speaking, the power loss of the transformer includes: iron loss, copper loss.
Iron loss refers to the loss caused by magnetic flux leakage in the iron core, while copper loss is the loss caused by the current flowing over the transformer coil (the coil has resistance).
For transformer parameters, there are mainly two losses: no-load loss and negative loss (full negative loss).
The difference is that the current flowing through the coil is different in both cases, so the heat generated is not the same, and the loss is also different.
Here are a few commonly used transformer parameters:
s11-10/。
200kva No load: 330W, Load: 2600W.
400kva No load: 570W, Load: 4300W.
630kva No load: 810W, load: 6200W.
A transformer is a device that uses the principle of electromagnetic induction to change the alternating 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.
Transformers can be divided into distribution transformers, power transformers, fully sealed transformers, combined transformers, dry-type transformers, oil-immersed transformers, single-phase transformers, electric furnace transformers, rectifier transformers, reactors, anti-interference transformers, lightning protection transformers, box-type substation test transformers, corner transformers, high-current transformers, excitation transformers, etc.

The landlord refers to the deterioration, right? This thing can refer to the factory manual of the transformer.

The electric loss of 200kVA transformer is: 900W*200=180000W. Because transformers have power loss, transformers with a capacity of 1kVA are generally about 900W.
The loss of the transformer is divided into two parts: iron loss and copper loss
1: Copper loss of winding, p=i2ri, note that it is the effective value of the current. The total copper loss of the transformer is the algebraic sum of each winding, when the diameter of the wire is less than twice the penetration depth, the skin effect is not considered, and the DC resistance can be directly calculated, otherwise the AC resistance is used.
2: Iron loss, depending on the frequency and magnetic induction intensity, circuit working state, material, etc., for bipolar switch p=pb*gb is the product of unit iron loss and mass, and unipolar is half of it.

The 125K A transformer uses 15,000 kilowatt-hours of electricity, and the line loss is much.
The 125K A transformer uses 15,000 kilowatt-hours of electricity, and the line loss in the transformer (including iron loss and line loss) occupies about 2%-7% of the electricity, and about 2%-3% in the energy-saving S11 transformer. The line loss of the transformer refers to the heat generated by the resistance of the coil when the current passes through the transformer line. The formula p (line loss) = i 2 * r (internal resistance).
Looking at the sum of the field plexus according to the formula, the line loss is proportional to the square of the current. Therefore, the temperature rise of the transformer is mainly caused by iron loss and copper loss.

The 125K A transformer uses 15,000 kilowatt-hours of electricity, and the line loss is much.
Hello Dear Kiss I am happy to answer for you. The loss in the 100-700 degree transformer (including the iron loss and line loss) occupies about 2%-7% of the electricity, and about 2%-3% in the energy-saving S11 transformer. The line loss of a transformer refers to the heat generated by the resistance of the transformer coil when a current is passed through the transformer coil.
The formula p (line loss) = i 2 * r (internal resistance). From the perspective of the male lead, the line loss is proportional to the square of the current. Therefore, the temperature rise of the transformer is mainly caused by iron loss and copper loss.
The above is mine, I hope it can help you, I wish you a happy life! <>

The 125K A transformer uses 15,000 kilowatt-hours of electricity, and the line loss is much.
125kA transformer uses 15,000 kilowatt-hours of electricity, how much is the line loss 125 kVA transformer no-load loss is 10159kw 1250kva transformer no-load loss: watts, daily loss is: degrees), this is cold-rolled data; watts, the daily loss is:

What is the daily loss of a 50 kVA transformer? Thank you.
What is the daily loss of a 50 kVA transformer? Thank you, hello, it is not the electrical loss rate of the transformer, the transformer loss is divided into: active loss, reactive loss, active loss = active iron loss + active copper loss + line loss Reactive power loss = reactive iron loss + reactive copper loss, 50kVA transformer, no-load loss, full-load loss, the most in one day.

What is the approximate line loss of a 10kV distribution transformer and how to calculate it? How much is normal?
For transformer parameters, there are mainly two losses: no-load loss and negative loss (counting full negative he) The difference is that the current of the Liuxiang empty ridge through the coil is different in the two cases, so the heating caused is not the same, and the analysis loss of Ou Song Jin seepage plate is also different.
