What about oil immersed transformer fire?

& ldquo; YN, D11 & rdquo;, in which 11 indicates that when the working voltage phasor of the primary side line as the minute hand, 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 scientific research of power transformer oil is generally carried out according to the way of sampling. What are the common sampling methods and processes?

Falling foreign matters and piercing

Noise dispersion of dry-type transformer

Transformer is

After 24 hours of continuous trial operation with a certain load, the main body and accessories of the transformer are all normal, and the transformer will turn to all normal operation.

Interpretation and observation.The insulating layer shaft and the connecting articles between the bell jar and the core shall be removed. If it is a hanging bell inspection, the oil shall be pumped into the bottom of the bell jar before the bell jar can be removed.

When we apply oil immersed transformer, we all know that it works with the help of oil. What if the oil immersed transformer is on fire? What countermeasures should we do?

When the power transformer operates at full load, it needs a large reactive load. This reactive load shall be provided by the power supply and distribution system. If the transformer volume is too large, it will not only increase the initial project investment,TiberiaEconomic operation of power transformer,Tiberia315 KVA oil immersed transformer, expand the proportion of full load loss, reduce power factor and increase Internet loss. Such operation is neither economic development nor scientific.

Test conclusion.What is the reason for the shutdown of power transformer?

Several detection methods for installing transformer

From the appearance, the packaging types are different. The transformer core and electromagnetic coil can be seen immediately for dry-type transformer, and only the shell can be seen for oil immersed transformer;

Tiberia.Common problems of tap changer of power transformer

In terms of the place of use, dry-type transformers are mostly used in & ldquo; Fireproof and explosion-proof type & rdquo; It is easy to use in large and medium-sized engineering buildings and multi-storey buildings; The oil immersed transformer because of & ldquo; Accident & rdquo; There is likely to be oil or leakage after fire, and most application places leading to fire accidents are easy to choose in large and medium-sized engineering buildings and multi-storey buildings;

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, wind and sand.
