Electric arc phenomenon
The electric arc is a phenomenon which takes place as a consequence of a discharge which occurs when the voltage between two points exceeds the insulating strength limit of the interposed gas; then, in the presence of suitable conditions, a plasma is generated which carries the electric current till the opening of the protective device on the supply side.
Gases, which are good insulating means under normal conditions, may become current conductors in consequence of a change in their chemical-physical properties due to a temperature rise or to other external factors.
To understand how an electrical arc originates, reference can be made to what happens when a circuit opens or closes.
During the opening phase of an electric circuit the contacts of the protective device start to separate thus offering to the current a gradually decreasing section; therefore the current meets growing resistance with a consequent rise in the temperature.
As soon as the contacts start to separate, the voltage applied to the circuit exceeds the dielectric strength of the air, causing its perforation through a discharge.
The high temperature causes the ionization of the surrounding air which keeps the current circulating in the form of electrical arc. Besides thermal ionization, there is also an electron emission from the cathode due to the thermionic effect; the ions formed in the gas due to the very high temperature are accelerated by the electric field, strike the cathode, release energy in the collision thus causing a localized heating which generates electron emission.
The electrical arc lasts till the voltage at its ends supplies the energy sufficient to compensate for the quantity of heat dissipated and to maintain the suitable conditions of temperature. If the arc is elongated and cooled, the conditions necessary for its maintenance lack and it extinguishes.
Analogously, an arc can originate also as a consequence of a short-circuit between phases. A short-circuit is a low impedance connection between two conductors at different voltages.
The conducting element which constitutes the low impedance connection (e.g. a metallic tool forgotten on the busbars inside the enclosure, a wrong wiring or a body of an animal entered inside the enclosure), subject to the difference of potential is passed through by a current of generally high value, depending on the characteristics of the circuit.
The flow of the high fault current causes the overheating of the cables or of the circuit busbars, up to the melting of the conductors of lower section; as soon as the conductor melts, analogous conditions to those present during the circuit opening arise. At that point an arc starts which lasts either till the protective devices intervene or till the conditions necessary for its stability subsist.
The electric arc is characterized by an intense ionization of the gaseous means, by reduced drops of the anodic and cathodic voltage (10 V and 40 V respectively), by high or very high current density in the middle of the column (of the order of 102-103 up to 107 A/cm2), by very high temperatures (thousands of °C) always in the middle of the current column and – in low voltage - by a distance between the ends variable from some microns to some centimeters.
[ABB]Явление электрической дуги
Электрическая дуга между двумя электродами в газе представляет собой физическое явление, возникающее в тот момент, когда напряжения между двумя электродами превышает значение электрической прочности изоляции данного газа.
При наличии подходящих условий образуется плазма, по которой протекает электрический ток. Ток будет протекать до тех пор, пока на стороне электропитания не сработает защитное устройство.
Газы, являющиеся хорошим изолятором, при нормальных условиях, могут стать проводником в результате изменения их физико-химических свойств, которые могут произойти вследствие увеличения температуры или в результате воздействия каких-либо иных внешних факторов.
Для того чтобы понять механизм возникновения электрической дуги, следует рассмотреть, что происходит при размыкании или замыкании электрической цепи.
При размыкании электрической цепи контакты защитного устройства начинают расходиться, в результате чего постепенно уменьшается сечение контактной поверхности, через которую протекает ток.
Сопротивление электрической цепи возрастает, что приводит к увеличению температуры.
Как только контакты начнут отходить один от другого, приложенное напряжение превысит электрическую прочность воздуха, что вызовет электрический пробой.
Высокая температура приведет к ионизации воздуха, которая обеспечит протекание электрического тока по проводнику, представляющему собой электрическую дугу. Кроме термической ионизации молекул воздуха происходит также эмиссия электронов с катода, вызванная термоэлектронным эффектом. Образующиеся под воздействием очень высокой температуры ионы ускоряются в электрическом поле и бомбардируют катод. Высвобождающаяся, в результате столкновения энергия, вызывает локальный нагрев, который, в свою очередь, приводит к эмиссии электронов.
Электрическая дуга длится до тех пор, пока напряжение на ее концах обеспечивает поступление энергии, достаточной для компенсации выделяющегося тепла и для сохранения условий поддержания высокой температуры. Если дуга вытягивается и охлаждается, то условия, необходимые для ее поддержания, исчезают и дуга гаснет.
Аналогичным образом возникает дуга в результате короткого замыкания электрической цепи. Короткое замыкание представляет собой низкоомное соединение двух проводников, находящихся под разными потенциалами.
Проводящий элемент с малым сопротивлением, например, металлический инструмент, забытый на шинах внутри комплектного устройства, ошибка в электромонтаже или тело животного, случайно попавшего в комплектное устройство, может соединить элементы, находящиеся под разными потенциалами, в результате чего через низкоомное соединение потечет электрический ток, значение которого определяется параметрами образовавшейся короткозамкнутой цепи.
Протекание большого тока короткого замыкания вызывает перегрев кабелей или шин, который может привести к расплавлению проводников с меньшим сечением. Как только проводник расплавится, возникает ситуация, аналогичная размыканию электрической цепи. Т. е. в момент размыкания возникает дуга, которая длится либо до срабатывания защитного устройства, либо до тех пор, пока существуют условия, обеспечивающие её стабильность.
Электрическая дуга характеризуется интенсивной ионизацией газов, что приводит к падению анодного и катодного напряжений (на 10 и 40 В соответственно), высокой или очень высокой плотностью тока в середине плазменного шнура (от 102-103 до 107 А/см2), очень высокой температурой (сотни градусов Цельсия) всегда в середине плазменного шнура и низкому падению напряжения при расстоянии между концами дуги от нескольких микрон до нескольких сантиметров.

16 "дуговая" неисправность
"дуговая" неисправность
Неисправность, приводящая к возникновению дуги.
[Интент]Параллельные тексты EN-RU
An arc fault occurs when there is a reduction in the dielectric strength of the insulating means (air, in LV switchboards) interposed between two or more conducting elements at different potential.
The arc is generated at the moment when, due to the high ionization of the air, there is a breakdown of the dielectric of the medium and the consequent flow of the current through it.
In an arc fault the highest stresses are of thermal type and proportional to RaI2 owing to the high value taken by the arc resistance Ra; this because the fault current flows in a medium which is always insulating, even if extremely ionized.
Such stresses manifest themselves essentially in the form of:
• high thermal gradients caused by the quick and intense rise in the air temperature;
• high pressure gradients in the form of pressure wave;
• high ionization of the air with consequent reduction of its insulating strength.
Generally speaking, in a LV assembly designed and tested according to the Standard IEC 60439-1 an arc fault is not very likely to occur; however, should it occur, the consequences would be extremely harmful to both the equipment as well as the personnel (see Chapters 2.2 and 2.3).
The causes of an arc fault can be both technical as well as non technical; among the latter the most frequent are the following:
• personnel errors, above all during maintenance operations;
• installation operations not sufficiently accurate;
• inadequate maintenance, above all in the case of severe environmental conditions.
Among the technical causes of an arc fault in a LV assembly the following ones are to be remembered:
• breakdown of the insulation essentially in the proximity of the supports of the busbars and of the plug-in contacts of the withdrawable units (75% of cases);
• overvoltages generating disruptive discharges between the points at minimum clearances (15% of cases);
• constructional defects of the apparatus (10% of cases).
[ABB]К «дуговой» неисправности, относится неисправность, обусловленная уменьшением электрической прочности изолирующей среды (воздуха в НКУ) между двумя или более токоведущими частями, находящимися под разными электрическими потенциалами.
Дуга образуется в тот момент, когда вследствие высокой ионизации воздуха происходит пробой изолирующей среды, вследствие чего через нее начинает протекать электрический ток.
Проявлением дуговой неисправности, является тепловое воздействие, пропорциональное RaI2 и достигающее большого значения вследствие большого сопротивления дуги Ra.
Дело в том, что ток дуги протекает через среду, которая всегда является изолирующей, пусть даже и чрезвычайно ионизированной.
Указанные воздействия очевидны сами по себе особенно в форме:
• теплового градиента температуры, вызванного быстрым и интенсивным подъемом температуры воздуха;
• высоким градиентом давления в форме волны давления;
• высокой ионизацией воздуха с последующим уменьшением электрической прочности.
Вообще говоря, в НКУ, разработанных и испытанных в соответствии с требованиями стандарта МЭК 60439-1 «дуговая» неисправность маловероятна. Однако, если дуга все таки возникнет, ее последствия буду чрезвычайно тяжелыми как для оборудования, так и для персонала (см. п. 2.2 и 2.3).
Причина дуговой неисправности может носить как технический, так и нетехнический характер. Среди последних наиболее часто возникают следующие:
• ошибки персонала, совершаемые главным образом во время технического обслуживания;
• недостаточно аккуратное выполнение монтажа;
• ненадлежащее техническое обслуживание, главным образом при эксплуатации НКУ в тяжелых условиях окружающей среды.
Среди технических причин дуговой неисправности в НКУ необходимо помнить о следующих:
• пробой изоляции, особенно вблизи опор шин и втычных контактов выдвижных частей НКУ (75 % случаев);
• перенапряжения, вызываемые разрушительными электрическими разрядами между точками с минимальными зазорами (15 % случаев);
• конструктивные дефекты аппаратуры (10 % случаев).
