接地保護(hù)電流繼電器聯(lián)系方式 優(yōu)質(zhì)電力系統(tǒng)電流繼電器型號
    SD-JLE22F/G型（F型為嵌入式安裝，G型為導(dǎo)軌式安裝）定時限電流繼電器（以下簡稱電流繼電器）是一種針對發(fā)電機、變壓器、輸變電線路的保護(hù)裝置，作為電力系統(tǒng)交流回路過負(fù)荷或短路的啟動元件，給出報警信號或切斷故障回路。
    SD-JLE22F/G type(F type is embedded installation, G type is rail-style installation) definite time lag current relay(hereinafter, current relay) is a kind of protection device for power generator, voltage transformer, power-transmission lines, as the starting element of the power system AC circuit overload or short circuit to give off alarms or cut off the fault circuit.
    該產(chǎn)品采用微機控制芯片，具有測量范圍寬、精度高、報警延時和動作延時分別設(shè)置與控制。配合 SD-LJD（LXK）系類零序電流互感器和動作繼電器即組成完整的零序（接地）保護(hù)系統(tǒng)。適用于AC690V及以下電網(wǎng)系統(tǒng)。
    The product is using microcomputer-co***olled chip, having the features such as wide range of measurement, high precision, alarm time delay and operating time delay can be set and co***olled separately. Used together with SD-LJD(LXK) series ZCT and executing relay to form a complete zero sequence(ground) protection system. It applies to power system up to AC690V.
