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.
