每隔20～30年,开关设备领域就会出现一次重大技术革新。空气和油开断技术逐步被SF6和真空开断技术所取代;保护装置从机械式演变为数字式;电流和电压互感器日益适应于新型继电器设计和创新的开关架构。如今,一场新的变革已然来临。2012年12月1日,全球能效管理专家施耐德电气正式推出一款为中压配电领域带来重大技术革新的产品,采用屏蔽式固体绝缘技术(2SIS)的开关设备——Premset。“近几年,智能电网技术的不断进步促使电力用
Every 20 to 30 years, there will be a major technological innovation in the field of switchgear. Air and oil breaking technology is gradually replaced by SF6 and vacuum breaking technology; protection devices evolve from mechanical to digital; current and voltage transformers are increasingly adapted to new relay designs and innovative switching architectures. Now a new revolution has come. On December 1, 2012, Schneider Electric, a global energy efficiency management expert, officially launched a premise that brings significant technological innovations in the field of medium voltage distribution using the shielded solid insulating technology (2SIS) switchgear. ”In recent years, the continuous improvement of smart grid technology to promote electricity use
