工作原理 在两侧电源时，在小电流源侧继电器近处发生短路的不利情况下，电流数值相差可能不大，但由于电流方向相反 (φ=180°)，由于制动回路两绕组的电势极性相反，继电器的制动系数Kr=Ip/Ir=1.1，从而提高了保护的灵敏性。 SSJ-31A/Ⅲ时间继电器调试方法 继电器的动作电流不大于额定电流 (2.5A或5A) ，动作电流大于额定电流的原因，是中间元件电磁铁与动铁之间气隙过大。 SSJ-31A/Ⅲ时间继电器相关型号 JZJ-218 HY-11B DZB-259X MGL-15 JDZ2-S31 BS-71D/Ⅱ ST3PF(T1) JL-311H DZY-214 JL8-33 JSS1P1-05/M HJZ-Y906 BTJ-1/B JXC-UA3 JZ-21/07 JZY-004C SS-13 ZNS-103A DSJ-13 BS-173A/C JZJ-214 HSL-26 DZB-257X MA-406A JDZ2-S11 ST3PC-A JL-311D DZY-213 JL-8-31A JSS-16 HJZ-Y904 BTJ-1/A JXC-IC1 JZ-17 JZX-18 SRTT-24VDC-2H2D-B ZJY-420 DSJ-12H JZJ-210 HSL-22 DZB-254X LY-55B JDZ-2B BS-71D/Ⅰ ST3PA-A JL-31 DZY-212 JL-8-23A JSS-14 HJZ-Y902 BTJ-1 JXC-IB4 JZ15D-44 BS-140 JZS-333/600 SRTT-220VDC-2H2D-C ZJY-080 DSJ-12E BS-173A JZJ-206 HSL-14 DZB-249X LY-52A/C JDZ2-52K SSJ8-32 JL-2C DZY-211 JL-8-22 JSS-13 HJZS-E202 BT-2 JXC-IA5 JZ15-44Z JZS-331/400B SRTT-220VAC-2H2D-C ZJX-3A DSJ-12 JZJ-202 HS-2362/1 DZB-248X LY-36 JDZ2-22 BS-71D SSJ-82A JL-25-43B DZY-210 JL8-21 JSS-12 HJZS-98 BT-1E JXC-IA1 JZ15 JZS-321/300 SRTT-110VDC-2Z-A ZJS-400/2 DSJ-11H BS-173 JZJ1-4 HS-2352/1 DZB-244X LY3 JDZ-1B SSJ8-21D JL-25-42A DZY-209 JL8-13 JSS1-10F HJZS-95 BT-1B/901B/R JX-9B JZ14-44J JZS2-600C SRTT-110VAC-2Z-B ZJS-1 DSJ-11E JZJ-006 HS-2342/1 DZB-243X LXB-1E JDZ1-52K BS-71C/ⅡC SSJ8-12D JL-23C DZY-208 JL-8-11A JSS-11 HJZS-91 BT-1B/90 JX-8-U-21B1 JZ1-30 BS-14 JZS-249 BS-113A SRTST-24VDC-1H1D-1H1D-C ZJL-420 DSJ-11 BS-172B/C JZFY-24 HS-2332/1 DZB-236X LLG-5A JDZ1-22 SSJ8-11B JL-23A/D DZY-207 JL-73 JSS1-09E HJZ-J923 BT-1B/2001B/R JX-8-U-11A JZ11-80ZS JY-40UB JZS-236 SRTST-220VDC-1H1D-1H1D-A ZJL-080 DSJ-10E JZC-3B/A DZB-233X LL-63A JDY-8-31 BS-71C/Ⅱ SSJ-79CD/T1 JL-22E BCH-2 DZY-206 JL-71E/ JSS1-08E HJZ-J921 BT-1B/200 JX-8-I-21B1 JZ11-62JP JY-40UA JZS-229/T SRTST-110VDC-1H1D-1H1D-B ZJJ-602 DSJ-10 BS-172B JZB4-310A DZB-229X LL-61A JDY-8-11 SSJ-79BD/T1 JL-22B/C DZY-205 JL-63 JSS1-07/M HJZ-J919 BT-1B/1B/R JX-8-I-11A JZ11-44 JY-40B/1e-6e JZS-227 SRTSD-220VDC-1H1D-1H1D ZJJ-3SA DS-38C/X JZB3-400B DZB-228X LL-42 JDY-11 BS-71C/Ⅰ 找发电机后备保护测控装置就上：http://www.jdbhw.com/Products_Detial/8/107.html
