treatment of gases
Gas is treated before it can be supplied to the marketplace. The extent to which gas needs to be processed will depend on its quality, the amount of associated impurities such as water, carbon dioxide and sulphur compounds, and the ultimate end-use for the gas. Common gaseous impurities found in natural gas are carbon dioxide and sulphur compounds. Both have an acidic reaction and are given the generic name 'acid gases'. These gases can be removed by a number of commercial processes, using either a physical or a chemical solvent. Physical solvent processes tend to be used where gas pressures are high and for gases with lower levels of propane and heavier hydrocarbons. (Source: SHELL)

arc-resistant switchgear
A type of switchgear design which is designed to withstand the effects of an internal arcing fault, without causing harm to personnel who are located in defined areas. It is not intended to withstand these internal arcing fault without possibly causing physical damage to the structure and/or components, but often the physical damage is less with an arc-resistant design.
There are three classes of protection:
Type A - eliminates the emission of gases and particles from the front of the switchgear during an internal arcing fault,
Type B - eliminates the emission of gases and particles from the front and sides of the switchgear during an internal arcing fault,
Type C - eliminates the emission of gases and particles from the front and sides of the switchgear, from between compartments within the same cell, and between adjacent cells during an internal arcing fault.
Arc-resistant switchgear has traditionally been metal-clad, but the basic concept could also be applied to other types of switchgear as well.
arc-proof switchgear
An incorrect term. Please refer to arc-resistant switchgear
[Schneider Electric]
[ http://electrical-engineering-portal.com/glossary-of-medium-voltage-switchgear-terms]Параллельные тексты EN-RU
If the electric arc occurs inside LV switchgear it generates internal overpressures and results in local overheatings which may cause high mechanical and thermal stresses in the equipment.
Besides, the involved materials can generate hot decomposition products, gases or fumes, which, due to the overpressure, are almost always ejected to the outside of the enclosure thus jeopardizing the operator safety.
The European Directive 2006/95/EC states the fundamental safety requirements for low voltage electric materials (from 50 V to 1000 V in alternating current, from 75 V to 1500 V in continuos current) to be put on the market within the European Community.
Among the essential safety requirements defined by this Directive particular importance is given to the need of taking technical measures to prevent “temperature rises, electric arcs or radiations which may result in hazards” from occurring.
This aspect has always been highly considered for apparatus, but it has been wrongly neglected for electrical switchgear and only in the last 10-15 years it has been catching on both at Italian as well as at international level.
Safety for the operator and for the installation in case of arcing inside LV switchgear can be obtained through three different design philosophies:
1. assemblies mechanically capable of withstanding the electric arc (passive protection)
2. assemblies equipped with devices limiting the effects of internal arcing (active protection)
3. assemblies equipped with current limiting circuitbreakers.
These three solutions (also combined together) have found a remakable development in the industrial field and have been successfully applied by the main manufacturers of LV switchgear and controlgear assemblies.
As it can be seen hereafter by examining the first two solutions, an “active” protection against arc faults is intrinsecally more complex than a “passive” one.
This because of the presence of additional electromechanical/ electronic devices5 which limit the arcing effects and which, by their nature, may be subject to faults or not-tripping.
[ABB]Дуга, возникшая внутри НКУ, создает внутреннее избыточное давление и вызывает локальный перегрев, что может привести к воздействию на оборудование значительного механического напряжения и перепада температур.
Кроме того, под воздействием дуги различные материалы разлагаются на продукты, имеющие высокую температуру, в том числе газы и дым, которые почти всегда вырываются из оболочки НКУ под высоким давлением, подвергая опасности оперативный персонал.
Европейская директива 2006/95/EC определяет основные требования безопасности для низковольтного (от 50 до 1000 В переменного тока и от 75 до 1500 В постоянного тока) оборудования поставляемого на рынок Европейского Сообщества.
Одно из основных требований безопасности, определяемое данной директивой как наиболее важное, заключается в необходимости предпринять технические меры для предотвращения "подъема температуры, возникновения электрической дуги или излучения", которые могут причинить ущерб.
Данная проблема всегда учитывалась при создании различных аппаратов, но незаслуженно игнорировалась при разработке электрических комплектных устройств, и только в последние 10-15 лет ей стали уделять должное внимание как в Италии, так и во всем мире.
При возникновении электрической дуги внутри НКУ безопасность оператора и электроустановки обеспечивается тремя способами:
1. Конструкция НКУ должна выдерживать механические воздействия, возникающие при горении электрической дуги (пассивная защита).
2. НКУ должно быть оснащено устройствами, ограничивающими воздействие электрической дуги (активная защита)
3. НКУ должны быть оснащены токоограничивающими автоматическими выключателями.
Указанные три способа (применяемые совместно) получили дальнейшее развитие в промышленности и успешно применяются основными изготовителями НКУ распределения и управления.
Как будет показано далее при рассмотрении первых двух способов, активная защита от дуговых» неисправностей является более сложной, чем пассивная защита.
Это объясняется необходимостью использования дополнительных электромеханических или электронных устройств, задачей которых является ограничение воздействий дуги и которые сами могут оказаться неисправными и не сработать.

Assemblies mechanically capable of withstanding the electric arc (passive protection)
The switchboards which take constructional precautions suitable to the containment of the arc and to the successive outlet of the exhausted gases belong to this type of assemblies.
Two are the peculiar characteristics of these types of switchgear:
• reinforced mechanical frame able to withstand the stresses (overpressures) caused by internal arcing;
• creation inside the assembly of a preferential path for the discharge of the hot gases generated by arcing.
Both characteristics are indispensable to satisfy the safety requirements for the operator and the installation established by the Document IEC 61641.
As a consequence, the manufacturers take design measures to prevent the accidental opening of the doors (or their perforation) due to the pressure wave generated by the arc.
Besides, also the instruments which can be positioned on the doors must be able to withstand an overpressure of about 1bar (=1kg/cm2) without being ejected and projected outside the switchboard.
The thermal consequences of arcing (exhausted gases at high temperature) are then limited by designing the inside of the switchgear so that the outlet of gases takes place in the top part (over 2 m) and not at lower heights which might be potentially dangerous for the operator.
It is evident that each opening of significant dimensions on the doors might constitute a vent for the gases and result dangerous for the operator; therefore such openings are usually avoided in this type of switchgear.
[ABB]НКУ, стойкие к механическому воздействию электрической дуги (пассивная защита)
К данному типу НКУ относятся такие устройства, конструкция которых предусматривает противостояние механическому воздействию электрической дуги и обеспечивает выхлоп образующихся газов.
В НКУ указанного типа используются два специальных конструктивных решения:
• усиленный каркас, способный противостоять нагрузке (избыточному давлению) возникающему при воздействии электрической дуги внутри НКУ;
• установленный внутри НКУ периферийный канала для выпуска горячих газов, образующихся в процессе горения дуги.
Согласно документу МЭК 61641 для удовлетворения требований безопасности оператора и электроустановки наличие обоих конструктивных решений является обязательным условием.
В результате изготовители используют конструктивные решения, направленные на предотвращение случайного открытия дверей (или их отверстий) при возникновении волны избыточного давления создаваемого электрической дугой.
Кроме того, приборы, размещаемые на дверях должны выдерживать избыточное давление, равное приблизительно 1 бар (1 кг/см2) и оставаться при этом на своих местах (не выдвигаться из комплектного устройства наружу).
Газы, возникающие при горении дуги, имеют высокую температуру.
Конструкция НКУ должна обеспечивать выход газов в верхней части (на высоте более 2 м) и не допускать выход газа в нижней части, поскольку это опасно для оператора.
Совершенно очевидно, что каждое достаточно большое отверстие в дверях шкафа может пропускать газы, и это опасно для оператора.
Поэтому, в НКУ рассматриваемого типа такие отверстия обычно отсутствуют.

Effects of the electrical arc on human beings
From the above, it is evident that the electrical arc represents a hazard source for people and goods.
The hazards to which a person is exposed due to the release of energy generated by an arc event are:
• burns;
• injuries due to ejection of materials;
• damages to hearing;
• inhalation of toxic gases.
Burns
The high temperature levels of the gases produced by the electrical arc and the expulsion of incandescent metal particles may cause more or less severe burns to people.
Flames can cause all degrees of burn up to carbonization: the red-hot solid bodies, such as the metal fragments of the assembly involved, cause third degree burns, superheated steam causes burns analogous to those by hot liquids whereas radiant heat generally causes less severe burns.
Injuries due to ejection of materials
The ejection of metal particles or other loose items caused by the electrical arc can result in severe injuries to the weakest parts of the human body as, for example, the eyes.
The materials expelled owing to the explosion produced by the arc may penetrate the cornea and hurt it.
The extent of the lesions depends on the characteristics and on the kinetic energy of these objects.
Moreover, the ocular region can sustain injuries to the mucosa because of the gases released by the arc and the emission of ultraviolet and infrared rays can injure the cornea and the retina depending on the radiation wavelengths.
Hearing
As already mentioned, the electrical arc is a real explosion, whose sound may cause permanent injuries to hearing.
Inhalation of toxic gases
The fumes produced by burnt insulating materials and by molten or vaporized metals can be toxic.
The fumes are caused by incomplete burning and are formed by carbon particles and by other solid substances suspended in the air.
[ABB]Воздействие электрической дуги на человека
Из сказанного выше совершенно очевидно, что электрическая дуга является источником опасности для людей и имущества.
При высвобождении энергии электрической дуги человек может подвергнуться следующим опасностям:
• получение ожогов;
• повреждения от выброса продуктов горения дуги;
• нарушение слуха;
• вдыхание ядовитых газов.
Ожоги
Высокая температура газов, образующихся при горении электрической дуги, и выброс раскаленных частиц металла могут явиться причиной достаточно тяжелых ожогов.
Можно получить любую степень ожогов, вплоть до обугливания. Раскаленные до красна твердые частицы, такие как металлические частицы НКУ, вызывают ожоги третьей степени. Перегретый пар вызывает ожоги, аналогичные ожогам от горячих жидкостей. Лучистая энергия вызывает менее тяжелые ожоги.
Повреждения от выброса продуктов горения дуги
Выброс металлических или иных частиц, происходящий при горении электрической дуги, может привести к серьезным телесным повреждениям, особенно при попадании в глаза.
Частицы, выбрасываемые при горении дуги, могут проникнуть в роговую оболочку глаза и повредить ее.
Степень поражения зависит от характеристик и кинетической энергии выбрасываемых частиц.
Кроме того, газы, выделяющиеся в процессе горения дуги, могут повредить слизистую оболочку глаз, а ультрафиолетовое и инфракрасное излучение – роговую оболочку и сетчатку в зависимости от длины волны воздействующего излучения.
Орган слуха
Как уже упоминалось, электрическая дуга представляет собой реальный взрыв, звук которого может нанести тяжелую травму органу слуха.
Вдыхание ядовитых газов
Продукты горения изоляционных материалов и пары металлов могут быть ядовитыми.
Дым, образующийся при неполном сгорании и содержащий частицы углерода и других веществ, попадает в окружающий воздух.
