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

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.
