AI Technical Summary

Technical Problem

In distributed photovoltaic power plants, the current technology for DC-side branch isolation operation is high-risk and inefficient, making it difficult to achieve fast, remote, and safe electrical isolation. Moreover, existing equipment is costly and complex in structure, failing to meet the dual requirements of remote real-time control and operation and maintenance safety.

Method used

Design a remotely disconnectable fuse that receives a remote signal through a micro-motion component to drive the movable section to disconnect, and extinguishes the arc with an arc-extinguishing medium to achieve safe and arc-free electrical isolation.

Benefits of technology

It achieves safe, arc-free, and rapid remote isolation of high-voltage DC circuits, reducing operational risks and improving maintenance safety and equipment reliability.

Abstract

本发明公开了一种可远程断开的熔断器,包括第一电极、第二电极,以及电气连接在第一电极与第二电极之间的熔体组件,熔体组件的周围设置有灭弧介质;熔体组件包括连接设置的可熔段和可动段,可动段设有脆性材质的易断部,可动段的一端设置有微动组件,微动组件包括电驱件和可远程通讯的通讯件,微动件的作用端与可动段连接;其中,通讯件被配置为在接收到远程断开指令时,驱动微动件运行,以推动可动段移动压断易断部,使可动段与可熔段之间产生电气隔离,且在拉断过程中产生的电弧由灭弧介质熄灭;通过将远程控制与熔断器自身灭弧能力相结合,提供受控远程断开能力,实现了高压直流回路的安全、无弧、快速远程隔离。
