How to choose a 10kV distribution transformer?

Some newly built commercial and residential communities are densely built and have a large installation load. The distance between distribution transformers in the community is short. Among the line losses of the distribution network in the area, the loss of distribution transformers accounts for a larger proportion.

The newly-built community has a low occupancy rate, a lighter load and a more scattered area. The distribution projects in the community generally install distribution transformers in one step according to the planned power load, which causes serious waste.

Single Phase Transformer in Canada

In addition, the peak load in summer is lighter than the load in winter, and there will be waste every winter. The traditional way to solve this problem is to replace it with a small-capacity transformer.

For example, a 630 kVA distribution transformer is replaced with a 315 kVA distribution transformer, and the product parameters of a transformer factory are used as an example for calculation. The parameters of SC3-630/10 distribution transformer are:

P10=1 800 W, P1K=5 270 W, I1n=909.3 A; The parameters of SC3-315/10 distribution transformer are P20=1 200 W, P2K=3 150 W, I2n=454.7 A. Substituting formula (5) into I″=260.2 A.

High voltage electrical 3 Phase Transformer on concrete pole.

When the load current is less than 260.2 A, replacing the 630 kVA transformer with a 315 kVA transformer can reduce the loss of the transformer. If there are two adjacent 630 kVA distribution transformers, which are connected on the low-voltage side by a tie line, the load of the two distribution transformers will be supplied by one of them, and the other will be out of service for backup. According to formula (3), I’=375.8 A can be obtained.

If the tie line is very short, the loss of the tie line can be ignored. When the average load current of a single distribution transformer is less than 375.8 A, the above method can be used to reduce the loss of the transformer.

Suppose there are two adjacent 630 kVA distribution transformers, and compare the total losses of the two methods in the above example. If the average load current of a single distribution transformer is 200 A, and the two 315 kVA distribution transformers replace the 630 kVA distribution transformer with two 315 kVA distribution transformers, the loss of the two 315 kVA distribution transformers will be The sum is:

P2=2P20+2(I2/I22n) P2K=3619 W.

According to the latter method, a 630 kVA distribution transformer with 400 A load, its loss is: P1=P10+(I2/I21n)P1K=2820 W.

Obviously, if there are two adjacent distribution transformers, the latter method in the above example has a smaller total loss than the former method.

When the average load current of each distribution transformer is smaller, the loss reduction effect of the latter method in the above example is more significant. In practical applications, the low-voltage side tie line can be used to switch the operation mode by simply operating the low-voltage switch.

The replacement of transformers not only requires a lot of work, but also has a considerable number of spare transformers. The effect is not as good as the method of connecting wires, and it is not economically cost-effective. The tie-line method can be extended to multiple nearby transformers, and the critical load current can be obtained by simple calculations.

It is recommended to add a tie line on the low-voltage side in the design of the community distribution network. The wire diameter can be considered according to 1/3 to 1/2 of the rated load current of the distribution transformer. Flexible switching of the operating mode.

It should be the capacity, but now there is no 360KVA capacity segment. The upper and lower are 315KVA and 400KVA respectively. It is said that 400 generally refers to the distribution transformer of S11-M-400/10.
