To facilitate insulation.

What are the types of transformer windings ? What are the types of concentric windings?

Transformer Oil

The composition of transformer oil is very complex, mainly composed of naphthenic hydrocarbons, alkanes and aromatic hydrocarbons. Transformer oil plays two roles in distribution transformers: one is to insulate between transformer windings and windings, windings and cores and oil tanks. effect. The second is that the transformer oil will generate convection after being heated, which will radiate heat to the transformer core and windings. Commonly used transformer oil has three specifications, No. 10, No. 25, and No. 45. The label indicates the temperature when the oil starts to solidify below zero. For example, “No. 25” oil means that this oil starts to solidify at minus 25°C.

Three functions and performance requirements of transformer oil

Oill Tank

The location of the oil drum is usually above the 10 kv transformer. Daelim can design oil drums of different capacities according to different transformer requirements.

When the transformer is affected by temperature, expands or shrinks. The oil drum will fill the iron core and windings with oil through the oil pipeline. This can ensure that the core part of the 10 KV transformer is always in an insulated state. Ensure the smooth operation of the 10 KV transformer.

10 KV transformers are equipped with an oil standard, which is also a standard gauge for oil level. This is to allow the staff to better observe the size of the oil in the drum.

Insulating sleeve

It is the main insulation device outside the 10 kv transformer box, and most of the 10 kv transformer insulation sleeves use porcelain insulation sleeves.

The 10 kv transformer leads the high and low voltage winding leads of the transformer from the oil tank to the outside through the high and low voltage insulating bushings, so that the transformer windings are insulated from the ground (shell and core), and it is also the main part of the fixed lead connecting with the external circuit.

The high-pressure porcelain bushing is relatively tall and the low-pressure porcelain bushing is relatively short.


A device for changing the tap of the high-voltage winding of a transformer to adjust the tap position, which can increase or decrease the number of turns of the primary winding to change the voltage ratio and adjust the output voltage.

After the transformer is out of operation and disconnected from the grid, the position of the tap switch is manually changed, and the output voltage adjustment is called no-load voltage regulation.

Gas relay

The gas relay is installed between the connecting pipe of the transformer oil tank and the oil conservator, and is connected with the control circuit to form a gas protection device.

The upper contact of the gas relay and the light gas signal form a separate circuit, and the lower contact of the gas relay is connected to the external circuit to form a heavy gas protection.

The heavy gas action causes the high-voltage circuit breaker to trip and send out the heavy gas action signal.

Riot Tube

The riot tube is a safety protection device for the transformer , Installed on the large cover of the transformer, the anti-riot tube communicates with the atmosphere, the heat will vaporize the transformer oil in the event of a fault, and trigger the gas relay to send an alarm signal or cut off the power supply to avoid the fuel tank from bursting.

A Complete Guide to Dry-type Transformer

10kv Transformer Single Phase

In the early days, people mostly used three-phase four-wire power distribution technology to complete power supply in residential areas. This caused the serious power loss.

In order to achieve energy-saving goals. More and more communities are equipped with single-phase transformers. The 10KV transformer single phase can directly transmit 10 kV high voltage to every household.

The use of 10 kV transformer single phase reduces the line loss caused by power transmission. Conducive to improving economic efficiency.

10 kV transformer single phase has the advantages of small size and lightweight. Therefore, the 10 kV transformer single phase can reach the load center as far as possible.
This shortens the transmission radius of the low-voltage power grid and greatly reduces power loss.

The 10 kV transformer single phase is usually installed on a concrete pole with a length of 12 meters to 15 meters. It occupies a small area, so its use is less affected by topographical factors.

The Advantage of 10kv Transformer Single Phase

  • First, the use of cold-rolled silicon steel sheet, coiled core and flame technology can reduce the power consumption of single-phase equipment.
  • Second, combined core products are used in single-phase transformers. The thickness and grades of various silicon steel sheets are different, and the core structure is optimized.
  • Third, the no-load loss of a single-phase transformer with an amorphous alloy wound core structure can be further reduced, which truly realizes energy saving and consumption saving.

Taking power with a capacity of 50kVA as an example, the S9 three-phase load has a phase load power consumption of 170W, but the no-load consumption of the single D12 model is 110W, which is 35% lower than that of the S9 model.

The Features of 10kv Transformer Single Phase

First, the power distribution room uses 10kV lines to feed power to residential users or commercial offices.

Second, single-phase transformers are generally connected to households with low-voltage lines by hanging poles. This can shorten the length of the entrance line. Generally, the length of the entrance line cannot exceed 20 meters.

Third, the capacity of single-phase transformers should be selected reasonably to match the maximum power consumption of residential buildings, forming a situation of densely distributed small capacity.

Fourth, the electricity meter is a device for centralized recording of the amount of electricity used. It should be centrally installed in the meter box at the appropriate location in the corridor of the residential building, so that one meter per household can be accurately counted.

10kv Transformer Single Phase Application

When the electricity load in the 10kV distribution network is in a normal state, the current situation of excessive line loss can be reduced by reducing the equipment capacity. The load of the low-voltage distribution network changes at any time, which will occur with the time of electricity use, seasons, etc. Change.

In the 10kV distribution network design process, a single-three-mixed distribution transformer installation plan is generally adopted. This plan can be configured with one or more 10kv single-phase distribution transformers. According to the specific changes in the electrical load and the low-voltage power grid The operation mode of the single-phase transformer determines the capacity requirement of the single-phase transformer so that a more suitable transformer is selected for power supply.

10kv Transformer Single Phase Installation

The 10 kv single-phase transformer is designed to provide users with more stable electrical energy products and reduce various problems caused by excessive electrical load. There are usually three ways to install single-phase transformers, depending on the situation. Choose the appropriate installation method:

  • First, independent installation. There is no connection between the installation of the 10 kv single-phase transformer and other low-voltage power grids. The 10 kv single-phase transformer forms its own system and operates independently. In this installation method, the single-phase transformer is closest to the load center, especially in some suburbs and scattered villages.
  • Second, the branch type installation. In this installation method, the low-voltage branch line of the 10 kv single-phase transformer should be kept disconnected from the main line, and a new power supply should be connected. In order to achieve a good and smooth transition between the three-phase transformer power supply and the single-phase transformer power supply and the branch line.
  • Third, the main line type installation. This method is mainly applicable to the situation that there is no three-phase load at the end of the three-phase station area. First, disconnect the mainline and connect a 10 kv single-phase transformer to the end of the main line to realize the conversion between power sources.

Connection 10 kv Transformer Single-phase

When wiring a 10 kv single-phase transformer, there are mainly two schemes: manual lay-up and disassembly method and knife-switch conversion method.

  • Using manual lay-up and disassembly, a 10 kv single-phase transformer on the high-voltage side will use a drop-out fuse as the main controller for operation. On the low-voltage side, when the 10 kv single-phase transformer is put into operation, it is necessary to manually remove the mainline connection with the three-phase low-voltage power supply. Then lap the low-voltage side of a 10 kv single-phase transformer. When the single-phase transformer is out of operation, the low-voltage side of the 10 kv single-phase transformer needs to be removed, and then the three-phase low-voltage power supply mainline should be lapped back.
  • Using a four-pole double-throw switch for control can realize the conversion of a single-phase transformer power supply and a three-phase transformer power supply on the low-voltage side of the distribution network.
