They are usually installed on the load side of MV/LV transformers or generators.
These assemblies include one or more incoming units, bus ties and a relatively reduced number of outgoing units.
There are also present measuring instruments and other switching and control equipment.
These assemblies have a sturdy structure to withstand the electrodynamic stresses and the weight of big sized apparatus.
As a matter of fact peculiar characteristics of the power center are high rated currents and shortcircuit currents.
The constructional type is a cubicle structure, with metal enclosure and sections divided into compartments with selective access.
[ABB]Такие устройства обычно подключают на стороне нагрузки СВ/НВ трансформаторов или генераторов.
В их состав входят один или несколько блоков ввода, шины и относительно небольшое число блоков вывода.
В состав комплектного устройства первичного распределения электроэнергии входят также измерительные приборы, коммутационные устройства и средства контроля состояния.
Данные комплектные устройства имеют прочную конструкцию, способную выдерживать электродинамическое действие токов и вес крупногабаритной аппаратуры.
Центры распределения электроэнергии характеризуются высокими номинальным током и током короткого замыкания.
С точки зрения конструктивного исполнения они представляют собой многошкафное комплектное устройство в металлической оболочке, состоящее из секций, каждая из которых разделена на отсеки с независимым доступом.
[Перевод Интент]Safety enclosed boards are used for most new installations. Common terms used to designate equipment of this type are metal-enclosed switchgear and metal-clad switchgear.
Most safety enclosed boards are of the unit or sectional type. They consist of a combination of the desired number and type of standardized unit sections.
Each section is a standard factory-assembled combination of a formed steel panel and apparatus mounted on a steel framework.
Safety enclosed switchgear may be classified with respect to purpose of application as follows:
1. General medium- or high-voltage switchgear
2. Primary unit substations
3. Rectifier unit substations
4. Secondary unit substations or power centers
5. General low-voltage switchgear
6. Low-voltage distribution switchboards
7. Motor-control-center switchboards
