    Didn't he/she do well? Le jeu télévisé britannique The Generation Game fut présenté pendant de nombreuses années par un nommé Bruce Forsyth. Cette expression ("il/elle s'est bien débrouillé(e), vous ne trouvez pas?") était l'une des petites phrases qu'il employait immanquablement au cours de l'émission. Il utilisait cette formule en s'adressant au public lorsqu'un concurrent venait de terminer une épreuve. Aujourd'hui, on emploie cette expression pour féliciter quelqu'un sur un ton légèrement condescendant.

    chalk
    A soft, pure, earthy, fine-textured, usually white to light gray or buff limestone of marine origin, consisting almost wholly (90-99%) of calcite, formed mainly by shallow-water accumulation of calcareous tests of floating microorganisms (chiefly foraminifers) and of comminuted remains of calcareous algae (such as cocoliths and rhabdoliths), set in a structureless matrix of very finely crystalline calcite. The rock is porous, somewhat friable, and only slightly coherent. It may include the remains of bottom-dwelling forms (e.g. ammonites, echinoderms, and pelecypods), and nodules of chert and pyrite. The best known and most widespread chalks are of Cretaceous age, such as those exposed in cliffs on both sides of the English Channel. (Source: BJGEO)

    A switchboard as defined in the National Electrical Code is a large single panel, frame, or assembly of panels on which are mounted, on the face or back or both switches, overcurrent and other protective devices, buses, and, usually, instruments.
    Switchboards are generally accessible from the rear as well as from the front and are not intended to be installed in cabinets.
    The types of switchboards, classified by basic features of construction, are as follows:
    1. Live-front vertical panels
    2. Dead-front boards
    3. Safety enclosed boards( metal-clad)


    [American electricians’ handbook]

    Параллельные тексты EN-RU

    The switchboard plays an essential role in the availability of electric power, while meeting the needs of personal and property safety.

    Its definition, design and installation are based on precise rules; there is no place for improvisation.

    The IEC 61439 standard aims to better define " low-voltage switchgear and controlgear assemblies", ensuring that the specified performances are reached.

    It specifies in particular:

    > the responsibilities of each player, distinguishing those of the original equipment manufacturer - the organization that performed the original design and associated verification of an assembly in accordance with the standard, and of the assembly manufacturer - the organization taking responsibility for the finished assembly;

    > the design and verification rules, constituting a benchmark for product certification.

    All the component parts of the electrical switchboard are concerned by the IEC 61439 standard.


    Equipment produced in accordance with the requirements of this switchboard standard ensures the safety and reliability of the installation.

    A switchboard must comply with the requirements of standard IEC 61439-1 and 2 to guarantee the safety and reliability of the installation.

    Managers of installations, fully aware of the professional and legal liabilities weighing on their company and on themselves, demand a high level of safety for the electrical installation.

    What is more, the serious economic consequences of prolonged halts in production mean that the electrical switchboard must provide excellent continuity of service, whatever the operating conditions.

    [Schneider Electric]

    НКУ играет главную роль в обеспечении электроэнергией, удовлетворяя при этом всем требованиям по безопасности людей и сохранности имущества.

    Выбор конструкции, проектирование и монтаж основаны на чётких правилах, не допускающих никакой импровизации.

    Требования к низковольтным комплектным устройствам распределения и управления сформулированы в стандарте МЭК 61439 (ГОСТ Р 51321. 1-2000).

    В частности, он определяет:

    > распределение ответственности между изготовителем НКУ - организацией, разработавшей конструкцию НКУ и проверившей его на соответствие требованиям стандарта, и сборщиком – организацией, выполнившей сборку НКУ;

    > конструкцию, технические характеристики, виды и методы испытаний НКУ.

    В стандарте МЭК 61439 (ГОСТ Р 51321. 1-2000) описываются все компоненты НКУ.

    Оборудование, изготовленное в соответствии с требованиями этого стандарта, обеспечивает безопасность и надежность электроустановки.

    Для того чтобы гарантировать безопасность эксплуатации и надежность работы электроустановки, распределительный щит должен соответствовать требованиям стандарта МЭК 61439-1 и 2.

    Лица, ответственные за электроустановки, должны быть полностью осведомлены о профессиональной и юридической ответственности, возложенной на их компанию и на них лично, за обеспечение высокого уровня безопасности эксплуатации этих электроустановок.

    Кроме того, поскольку длительные перерывы производства приводят к серьезным экономическим последствиям, электрический распределительный щит должен обеспечивать надежную и бесперебойную работу независимо от условий эксплуатации.

    [Перевод Интент]

     

    LV switchgear assemblies are undoubtedly the components of the electric installation more subject to the direct intervention of personnel (operations, maintenance, etc.) and for this reason users demand from them higher and higher safety requirements.

    The compliance of an assembly with the state of the art and therefore, presumptively, with the relevant technical Standard, cannot be based only on the fact that the components which constitute it comply with the state of the art and therefore, at least presumptively, with the relevant technical standards.

    In other words, the whole assembly must be designed, built and tested in compliance with the state of the art.

    Since the assemblies under consideration are low voltage equipment, their rated voltage shall not exceed 1000 Va.c. or 1500 Vd.c. As regards currents, neither upper nor lower limits are provided in the application field of this Standard.

    The Standard IEC 60439-1 states the construction, safety and maintenance requirements for low voltage switchgear and controlgear assemblies, without dealing with the functional aspects which remain a competence of the designer of the plant for which the assembly is intended.

    [ABB]

    Низковольтные комплектные устройства (НКУ), вне всякого сомнения, являются частями электроустановок, которые наиболее подвержены непосредственному вмешательству оперативного, обслуживающего и т. п. персонала. Вот почему требования потребителей к безопасности НКУ становятся все выше и выше.

    Соответствие НКУ современному положению дел и вследствие этого, гипотетически, соответствующим техническим стандартам, не может основываться только на том факте, что составляющие НКУ компоненты соответствуют современному состоянию дел и поэтому, по крайней мере, гипотетически, - соответствующим техническим стандартам

    Другими словами, НКУ должно быть разработано, изготовлено и испытано в соответствии с современными требованиями.

    Мы рассматриваем низковольтные комплектные устройства и это означает, что их номинальное напряжение не превышает 1000 В переменного тока или 1500 В постоянного тока. Что касается тока, то ни верхнее, ни нижнее значение стандартами, относящимися к данной области, не оговариваются

    Стандарт МЭК 60439-1 устанавливает требования к конструкции, безопасности и техническому обслуживанию низковольтных комплектных устройств без учета их функций, полагая, что функции НКУ являются компетенцией проектировщиков электроустановки, частью которых эти НКУ являются.

    Star-delta Y/Δ starting

    Star-delta starting is the best known system and perhaps the commonest starting system at reduced voltage; it is used to start the motor reducing the mechanical stresses and limiting the current values during starting; on the other hand, it makes available a reduced inrush torque.

    This system can be used for motors with terminal box with 6 terminals and double supply voltage.

    It is particularly suitable for no-load starting or with low and constant load torque or lightly increasing load torque, such as in the case of fans or low power centrifugal pumps.

    Making reference to the diagram of Figure 6, the starting modality foresees the initial phase with star-connection of the windings to be realized through the closing of the circuit-breaker, of the line contactor KL and of the star contactor KY.

    After a suitable predetermined period of time, the opening of the contactor KY and the closing of KΔ allow switching to delta-connection, which is also the configuration of normal running position.

    Пуск переключением со звезды на треугольник

    Пуск переключением со звезды на треугольник является самым известным способом и, возможно, самой распространенной схемой пуска на пониженном напряжении. С одной стороны, этот способ используется для снижения механических нагрузок и ограничения пускового тока, а с другой - обеспечивает уменьшение пускового момента.

    Такая возможность может быть реализована в двигателях с шестью зажимами в выводной коробке, что позволяет питать его от двух напряжений.

    Особенно этот способ подходит для ненагруженного пуска и пуска с низким постоянным или немного увеличивающимся вращающим моментом, например, для пуска вентиляторов или маломощных центробежных насосов.

    Схема пуска переключением со звезды на треугольник представлена на рисунке 6. В начальный момент пуска обмотки статора соединяют звездой путем замыкания контактов автоматического выключателя, линейного контактора KL и контактора KY со схемой "звезда".

    По истечении заданного времени контакты контактора KY размыкаются и замыкаются контакты контактора КΔ со схемой треугольник.
    В результате выполняется переключение обмоток статора со схемы «звезда» на схему «треугольник».
    Обе схемы соединения обмоток являются схемами нормального рабочего режим

    tidal power
    Mechanical power, which may be converted to electrical power, generated by the rise and fall of ocean tides. The possibilities of utilizing tidal power have been studied for many generations, but the only feasible schemes devised so far are based on the use of one or more tidal basins, separated from the sea by dams (known as barrages), and of hydraulic turbines through which water passes on its way between the basins and the sea.
