Reduce Power And Distribution Transformer Losses
Dry-type power and distribution transformer is a very widely used transformer at present. It is a very important transformation equipment in the power system, but it is also a large energy consumer, and its loss accounts for half of the entire network loss. How can we reduce the energy consumption of dry-type transformers?
On the one hand, it is necessary to reduce the loss of the power and distribution transformer itself. Silicon steel sheets, steel, insulating materials, magnet wires, transformer oil, etc. are all necessary materials for transformers. These materials consume a lot of power. The saving of these materials directly saves power.
On the other hand, it reduces the loss of the power and distribution transformer. Transformer losses include no-load losses and load losses. In order to reduce the load loss, it is necessary to use copper materials or use transposition wires; in order to reduce the no-load loss and choose to reduce the magnetic density, silicon steel sheets or good silicon steel sheets are used more, which increases the production cost of the transformer. The sales price has also increased, which depends on how long the operation takes to recover the extra money. The gas storage inside the transformer is divided into two parts: one is the gas storage inside the insulating parts of the transformer body and the coil, and the other is the storage gas in the transformer body. It is the gas stored in the accessories of the transformer, including radiators, oil purifiers, pressure relief valves, oil conservators, etc. When the transformer body is evacuated, the space between them and the transformer body are mutually blocked. The internal space of the gas should be discharged. Therefore, it is necessary to exhaust the transformer after vacuum oil injection and oil replenishment. Exhaust is a very important operation. The specific method is: first go down and then go up, block the oil tank and drain it separately.
