GOST 21128-83

ГОСТ 21128-83

Power supply systems, nets, sources, converters and receivers of electric energy. Rated voltages to 1000 V

Системы электроснабжения, сети, источники, преобразователи и приемники электрической энергии. Номинальные напряжения до 1000 В

Status: Effective - Supersedes. IUS 2-1984

The standard applies to power supply systems, networks, sources, converters and directly connected to them receivers of electrical energy and sets for them a series of nominal values of constant and alternating voltages for frequencies according to GOST 6697-83. The standard does not establish the nominal values of voltages: corresponding to emergency, abnormal operating modes and transients; circuits closed within functional units, interstage connections of equipment, sources, converters and receivers of electrical energy; chains of products whose operation is not characterized by the principle of fixed voltage values (circuit of electric wires with motor speed regulation, etc.); circuits of reactive power compensation devices, protection, control and measurement; on the findings of cells and batteries; on the findings of primary measuring transducers; for electric vehicles (rail and trackless); on sources and means of secondary power supply of electronic equipment.

Стандарт распространяется на системы электроснабжения, сети, источники, преобразователи инепосредственно присоединяемые к ним приемники электрической энергии и устанавливает для них ряды номинальных значений постоянных и переменных напряжений для частот по ГОСТ 6697-83. Стандарт не устанавливает номинальные значения напряжений: соответствующих аварийным, ненормальным режимам работы и переходным процессам; цепей, замкнутых внутри функциональных узлов, межкаскадных соединений аппаратуры, источников, преобразователей и приемников электрической энергии; цепей изделий, работа которых по принципу действия не характеризуется фиксированным значениям напряжения (цепи электропроводов с регулированием скорости двигателя и др.); цепей устройств компенсации реактивной мощности, защиты, контроля и измерения; на выводах элементов и аккумуляторов; на выводах первичных измерительных преобразователей; для электрифицированного транспорта (рельсового и безрельсового); на источники и средства вторичного электропитания радиоэлектронной аппаратуры.
