transformateur immergé dans l'huile

[IEV number 421-01-14]Oil transformers
The magnetic circuit and the windings are immersed in a liquid dielectric that provides insulation and evacuates the heat losses of the transformer.
This liquid expands according to the load and the ambient temperature. PCBs and TCBs are now prohibited and mineral oil is generally used. It is flammable and requires protective measures against the risks of fire, explosion and pollution.
The most commonly used protective measures are the DGPT or the DGPT2: Gas, Pressure and Temperature sensor with 1 or 2 sensing levels on the temperature. This system cuts off the LV load (1st level) then the HV supply (2nd level) when there is a fault inside the transformer. A holding tank is used to recover all the liquid dielectric.
Of the four types of immersed transformer: free breathing transformers, gas cushion transformers, transformers with expansion tank and transformers with integral filling, only the latter are currently installed.
[Legrand]Масляные трансформаторы
Магнитная система и обмотки трансформатора погружены в жидкий диэлектрик, служащий изоляцией и теплоносителем.
Жидкий диэлектрик изменяет свой объем в соответствии с нагрузкой трансформатора и температурой окружающей среды. Поскольку в настоящее время применение полихлорированных дифенилов и тетрахлорбифенилов запрещено, то в основном используют минеральное масло. Оно огнеопасно, поэтому необходимо принимать меры против возникновения пожара, взрыва и загрязнения окружающей среды.
Как правило, применяются системы DGPT (одноуровневые системы, использующие датчики газа, давления и температуры) или DGPT2 – двухуровневые системы. В случае возникновения аномального состояния трансформатора данные системы отключают нагрузку цепей низшего напряжения (первый уровень защиты), а затем питание обмотки высшего напряжения (второй уровень защиты). Активная часть трансформатора находится в баке и полностью покрыта жидким диэлектриком.
Существует четыре типа масляных трансформаторов: трансформаторы с системой свободного дыхания, трансформаторы с газовой подушкой между зеркалом масла и крышкой трансформатора, трансформаторы с расширительным баком и трансформаторы с гофрированным баком. В настоящее время применяют только трансформаторы последнего типа

3 impact de l'énergie sur l'environnement
воздействие производства энергии на окружающую среду

[ http://www.eionet.europa.eu/gemet/alphabetic?langcode=en]EN
environmental impact of energy
Energy and environmental problems are closely related, since it is nearly impossible to produce, transport, or consume energy without significant environmental impact. The environmental problems directly related to energy production and consumption include air pollution, water pollution, thermal pollution, and solid waste disposal. The emission of air pollutants from fossil fuel combustion is the major cause of urban air pollution. Diverse water pollution problems are associated with energy usage. One major problem is oil spills. In all petroleum-handling operations, there is a finite probability of spilling oil either on the earth or in a body of water. Coal mining can also pollute water. Changes in groundwater flow produced by mining operations often bring otherwise unpolluted waters into contact with certain mineral materials which are leached from the soil and produce an acid mine drainage. Solid waste is also a by-product of some forms of energy usage. Coal mining requires the removal of large quantities of earth as well as coal. In general, environmental problems increase with energy use and this combined with the limited energy resource base is the crux of the energy crisis. An energy impact assessment should compare these costs with the benefits to be derived from energy use. (Source: RAU)

deep sea mining
The most valuable of the marine mineral resources is petroleum. About 15% of the world's oil is produced offshore, and extraction capabilities are advancing. One of the largest environmental impacts of deep sea mining are discharged sediment plumes which disperse with ocean currents and thus may negatively influence the marine ecosystem. Coal deposits known as extensions of land deposits, are mined under the sea floor in Japan and England. (Source: PARCOR / ERIB)

cash crop
Crops that are grown for sale in the town markets or for export. They include coffee, cocoa, sugar, vegetables, peanuts and non-foods, like tobacco and cotton. Huge areas of countries in the developing world have been turned over to cash crops. Those countries with no mineral or oil resources depend on cash crops for foreign money, so that they can import materials do develop roads, for construction, or to buy Western consumer goods and, indeed, food. However, critics argue that cash crops are planted on land that would otherwise be used to grow food for the local community and say this is a cause of world famine. Cash crops, such as peanuts, can ruin the land if it is not left fallow after six years of harvests. Moreover, if the best agricultural land is used for cash crops, local farmers are forced to use marginal land to grow food for local consumption, and this has a further dramatic effect on the environment.
