Vis\u00e3o geral<\/strong>
\nA unidade principal de anel de metal HXGN17-12 AC (interruptor de carga) (abreviada como unidade principal de anel) \u00e9 um novo tipo de aparelho de comuta\u00e7\u00e3o de alta tens\u00e3o desenvolvido para atender \u00e0s necessidades de renova\u00e7\u00e3o e constru\u00e7\u00e3o da rede el\u00e9trica urbana. Em sistemas de alimenta\u00e7\u00e3o, tamb\u00e9m \u00e9 usado para interromper correntes de carga e correntes de curto-circuito, bem como fechar correntes de curto-circuito. Esta unidade principal de anel est\u00e1 equipada com interruptores de carga de v\u00e1cuo FZRN25 e FZRN21 com um mecanismo operado por mola que pode ser operado manualmente ou eletricamente, interruptores de aterragem e facas de isolamento est\u00e3o equipados com mecanismos de manuaoperating, Esta unidade principal de anel apresenta uma forte integra\u00e7\u00e3o do sistema, tamanho compacto, nenhum risco de combust\u00e3o ou explos\u00e3o e fun\u00e7\u00f5es confi\u00e1veis de “cinco.preven\u00e7\u00e3o”.
\nEsta unidade principal de anel cumpre as disposi\u00e7\u00f5es relevantes das normas GB3906 “3-35kV AC Metal-Enclosed Switchgear” e lEc60420 “Unidades de combina\u00e7\u00e3o de alta tens\u00e3o AC LoadSwitch-Fuse”.<\/p>\n
