Insulation coordination for low-voltage power system equipment. Part 1. Principles, requirements and tests
Координация изоляции для оборудования низковольтных систем питания. Часть 1. Принципы, требования и испытания
Status: Accepted
This standard specifies insulation coordination requirements for equipment connected to low-voltage power systems and having a rated voltage up to and including 1,000 V AC or 1,500 V DC. This standard is applicable for frequencies up to and including 30 kHz. The standard applies to equipment intended for use up to 2,000 m above sea level and provides clarification for use at higher altitudes (see 5.2.3.4). The standard contains requirements for technical committees to determine air gaps, leakage paths and criteria for solid insulation, including electrical test methods related to insulation coordination. The minimum air gaps specified in this standard do not apply in the presence of ionized gases. Special requirements for such cases may be specified at the discretion of the appropriate technical committees. The requirements of this standard do not apply to air gaps and leakage paths: - through liquid insulation; - through gaseous media other than air; - through compressed air. It is a fundamental safety standard that emphasizes basic safety requirements and is primarily intended for use by technical committees in developing standards in accordance with the principles set out in IEC Guide 104 and ISO/IEC Guide 51. It is one of the tasks of the technical committee, where applicable, to use this fundamental safety standard in the preparation of its publications. However, where air gaps, leakage paths and solid insulation requirements are not specified in the relevant product standards or where no relevant standards are available, this standard shall apply
Настоящий стандарт устанавливает требования к координации изоляции для оборудования, подключаемого к низковольтным системам питания и имеющего номинальное напряжение до 1 000 В переменного тока или до 1 500 В постоянного тока включительно.
Настоящий стандарт применим для частот до 30 кГц включительно.
Стандарт применяется к оборудованию, предназначенному для использования на высоте до 2 000 м над уровнем моря и содержит пояснения при использовании на больших высотах (см. 5.2.3.4).
Стандарт содержит требования для технических комитетов по определению воздушных зазоров, путей утечки и критериев для твердой изоляции, в том числе методы электрических испытаний, относящиеся к координации изоляции.
Минимальные воздушные зазоры, указанные в настоящем стандарте, не применяются при наличии ионизированных газов. Специальные требования для таких случаев могут указываться на усмотрение соответствующих технических комитетов.
Требования данного стандарта не распространяются на воздушные зазоры и пути утечки:
- через жидкую изоляцию;
- через газообразную среду, иную, чем воздух;
- через сжатый воздух.
Это основополагающий стандарт по безопасности, в котором особое внимание уделяется основным требованиям безопасности и в первую очередь предназначен для использования техническими комитетами при разработке стандартов в соответствии с принципами, изложенными в IEC Guide 104 и ISO/IEC Guide 51.
Одна из задач технического комитета, где это применимо, использовать этот основополагающий стандарт по безопасности при подготовке своих публикаций.
Однако в случае отсутствия указания значений воздушных зазоров, путей утечки и требований к твердой изоляции в соответствующих стандартах на продукцию или в случае отсутствия соответствующих стандартов применяется настоящий стандарт
