Outdoor sampling shall be carried out in sunny days or dry weather with low environmental humidity. During sampling, it is necessary to resolutely prevent the invasion of dirt such as rain, snow, wind and sand.

In the electric field of the winding to the yoke, there must be a strong line breaking component, so that sliding flash charge and discharge may occur at a lower current. In order to better solve this disadvantage, the appearance of the insulating parts between the winding and the iron yoke should be the same as that of the medium horizontal plane of the winding to the iron yoke insulation as far as possible, so as to reduce the electric field component intersecting with the insulating parts.

Yangon.According to statistics, to occupy the main global technical position, the transformer industry depends on two key data, commodity volume and voltage level. As early as & ldquo; Eleventh Five Year Plan; In the early stage, China has been a powerful country in the production, manufacturing and application of dry-type transformers all over the world, but it is not a big country.

Performance parameters of key work clothes, machinery and equipment of each process flow; The natural working environment is basically regulated.

& ldquo; YN, D11 & rdquo;,YangonComplete list of Transformer Models, as the minute hand,YangonTransformer box, refers to the position at 12 o'clock, the phase voltage phasor of the secondary side is at 11 o'clock. That is, the phase voltage UAB of the secondary side lags 30 degrees behind the working voltage uab330 of the primary side line (or 30 degrees ahead).

The voltage regulating tap changer is not in place or poor

The common dry-type transformer is an important electrical equipment, and the voltage is constantly regulated. However, because of certain necessity, and the whole process of boosting voltage is very complex, and there are many principles.

The tap changer of power transformer shall also have strong insulation. 10kV off load tap changer is generally insulated from the ground by the produced insulating paper pipe factory.

knowledge.In specific daily life, oil immersed transformers are released outward in the form of waves. This kind of wave is like a tide. It is also a kind of kinetic energy. In fact, the wave height of oil immersed transformer also shows the size of kinetic energy. Generally computer automatic system is used to control the wavelength and frequency of electromagnetic wave. The longer the light wavelength is, the greater the output power is. On the contrary it is very small.

What is the important role of power transformer

After no-load test run is normal for 24h, and the load shall be gradually increased from 25%, 50% and 75% by grade.

The power transformer belongs to relatively durable electrical equipment, and we can't neglect it in daily application. The common problems of power transformer conductor, power transformer winding and power transformer tapping power switch are analyzed below:

Discount.The vibration reduction solution of cable bridge is to modify the hard connection between bus bridge and dry-type transformer, and the vibration reduction solution is made at the cable bridge.

The rate of transformer is: n = P2 / p1x1o%, that is, when the copper loss of transformer is equivalent to iron loss, the rate is very large. Therefore, the load of transformer is: 0 = P / PK. Fully consider the active power loss caused by reactive power in the system software during transformer operation. The load adjustment is: it can be seen from the calculation of load formula that the large rate of transformer does not occur when the load is full, Generally, it is about 50%, but when selecting the transformer capacity, we should select effective transformers according to the load condition and load, so as to make the transformer in the situation of economic development and achieve the goal of power saving.

After no-load test run is normal for 24h, it can be transferred to on-load operation, and the load shall be gradually increased from 25%, 50% and 75% by grade.

Yangon.Falling foreign matters and piercing

Oil immersed transformer operation

Insulation and heat removal are different. Dry type transformers are generally insulated with epoxy resin cooled by natural air and large capacity by centrifugal fan. Oil immersed transformers are insulated by insulating oil, insulated by insulating oil in the circulating system inside the transformer and heat is discharged on the radiator (radiator) of the circulating system inside the transformer.
