ZJ4中間繼電器產品概述 具有反時限特性，應用于電機、變壓器等主設備以及輸配電系統的繼電保護回路中。當主設備或輸配電系統出現過負荷及短路故障時，該繼電器能按預定的時限動作或發出信號，切除故障部分，主設備及輸配電系統安全。 ZJ4中間繼電器工作原理 繼電器是電磁式閥型的動片連著一塊彎板，彎板末端固定著頂板，當動鐵吸合時頂板推動動接觸片，于是動合觸點閉合。 ZJ4中間繼電器相關型號 HZB-22 JZJ-602 JDZY-1220 PTS3P-M BS-72D JL-31B/D SY-34/3 JQX-13F DZJ-20 JSW-13A JX-IB7 BZS-14J DZZ-13 JZ-21H/071J JZY-205X HJZZ-91/1 SS-27/3 BS-182B DX-111 HZB-115 JZJ-400B JDZY-1020 BLY-5 MY3 JL-31A/C SY-32/3 JPB-B DZJ-11 JSS48A-S JX-IB3 BZS-14 DZZ-11 JZ-21E/43J JZY-202C HJZ-Y924 SS-23 ZXX-2 DX-11 HYJY-30-02 JZJ-224 JDZS-1202A BS-145B/C MS4SC BS-72C/ⅡC JL-313H SY-22 JLK-33 DZBT-115 JSS3B JX-IA6 BZS-13J DZY-222 JZ-21/S21 JZY-12 HJZ-Y922 SS-20 ZSJ-3 BS-182A/C DX-10C HY-41A JZJ-220 JDZS-1004A MK2P-1 JL-313D ST3PY JLK-22 DZB-556 JSS20-R JX-IA2 BZS-13 DZY-221 JZ-21/43 JZY-042B HJZ-Y920 SS-17C ZNS-104SC BCD-9A DX-10B HY-31B JZJ-216 JDZL-1440 MGL-11 BS-72C/Ⅱ JL-312J ST3PC-E JLK1-4 DZB-555 JSS20-A JXG-10 BZS-12J DZY-220 JZ17-62 JZY-002 HJZ-Y918 SRTT-24VDC-2Z-C ZJY-602 BS-182A DX-10A HY-22 JZJ-212 JDZL-1200 LY-57B JL-312F ST3PA-E JLK1-2 DZB-553 JSS20-21AMZ JXC-UB7 BZS-12 DZY-219 JZ1-60 JZS-400/5 HJZ-Y916 SRTT-220VDC-4H-A ZJY-242 DX-10 HY-21 JZJ-208 JDZL-1004 AJL-31A/W BCH-4 BS-145B LY-53A/C BS-72C/Ⅰ JL-312B SSJ8-32D JLK-10B DZB-551 JSS1P1-09/M JXC-UB1 BS-122A BZS-11J～14J/80 DZY-218 JZ15-80 JZS-333/220A HJZ-Y914 SRTT-220VAC-4H-A ZJY-006 BS-182 DX-1 HY-11B JZJ-204 JDZ2-S31 LY-51A/C JL-311H SSJ8-31B JL8-33 DZB-284X JSS1P1-05/M JXC-UA3 BZS-11J～14J/62 DZY-217 JZ15-26J JZS-323/300 HJZ-Y912 SRTT-110VDC-4H-B ZJS-7/244A DT-13Q HSL-26 JZJ-200 JDZ2-S11 LY-32 BS-72C JL-311D SSJ8-22B JL-8-31A DZB-278X JSS-16 JXC-IC1 BZS-11J～14J/44 DZY-216 JZ14-62J/35 JZS-312/300 HJZ-Y910 SRTT-110VAC-4H-C ZJS-202/4 BS-181B/C DT-13E HSL-22 JZJ-080 JDZ-2B BL-4E LY2 JL-31 SSJ8-21 JL-8-23A DZB-262X JSS-14 JXC-IB4 BZS-11J～14J/26 DZY-215 JZ1-40 JZS-250X HJZ-Y908 SRTT-110VAC-2H2D-A ZJL-602 DT-13/L HSL-14 JZJ JDZ2-52K 找主變后備保護測控裝置就上：http://www.jdbhw.com/Products_Detial/8/108.html
