34 arc fault
- "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).
