剩余電流繼電器生產(chǎn)廠家-零序保護電流繼電器生產(chǎn)廠家
SD-ZLD 型漏電保護器是一種針對工業(yè)動力用電設(shè)備而設(shè)計的專用型智能漏電保護裝置。采用微機控制芯片，具有測量范圍廣、精度高等特點。
該產(chǎn)品同L型剩余電流互感器和斷路器組成漏電保護系統(tǒng)。適用于AC690V及以下電網(wǎng)系統(tǒng)，用于對末端線路或動力設(shè)備的漏電保護使用。為防止因漏電造成動力設(shè)備損壞以及人身觸電危險提供間接保護作用。
SD-ZLD type current leakage protection relay is a kind of smart device specifically designed for industrial power equipment. It takes microcomputer-controlled chip, having the features such as wide range of measurement, high precision and so on.
Used together with L type residual current transformer and circuit breaker forms current leakage protection system. It applies to power system up to AC690V for current leakage protection of the downstream line or power equipment, to prevent the power equipment and personnel from damage or electric shock indirectly cause of current leakage.
