工作原理 继电器若一相或两相断路时，变压器二次亦有输出电压，继电器动作。继电器接于发电厂及变电所内高压母线上电压互感器二次侧。当高压母线无电时，继电器释放，极化继电器的动断触点接通，闭锁解除，允许合接地刀闸。 DZJ-20/5300中间继电器产品概述 继电器用于直流操作的保护和自动控制装置中，作为实现机械保持手动复归的动作指示器。 DZJ-20/5300中间继电器相关型号 JZY-333/220 JS20/13 DJ-111 SS-72/1 JSZ8-01 JY-16A/61 DX-41A JZL-006C RXSF1 RK271016-X DY-24CE/C WQP-2B/3 HZH-24VDC-2H-2H-2D DZK-100T JGL-2/15 JZAC-3A/A JL-327H GZY-202/220V JZY-333/062 JS15SX DJ-100 SS-71/6C JSZ7-H BS-62A JY-156/1 DX-4 JZK-240X RXSF1 DY-24C/60C UEG/C-2H/110V HZH-24VDC-2H-1H1D-1D DZJ-29 JGL-2/11 JZ8-62Z JL-327D GZY-200/220V JZY-333/004 JS14PS-999S DH48S-S SS-71/20 JSZ4C-F BS-141A JY-152/1 DX-35/S JZK-220X RXMS1 RK216763 DY-24 UEG/A-4H-R/110V HZH-24VDC-1H1D-1H1D-1D DZJ-27 JGL-1A/14 JZ8-26Z JL-326H GL-26/5 JZY-311/220 JS14P-99S DH48S-2Z SS-71/17 JSZ4C-B BS-62/II JY-142E DX-35/D JZK-210X RXMS1 RK216450 DY-23D/60C UEG/A-4D-R/110V HZH-220VDC-2H-2H-1D DZJ-25 JGL-1A JZ7-44 JL-326D GL-26 JZY-225 JS14C DH48S SS-62/II JSZ4A-E JY-141E DX-34C JZK-141Q RXMS1 RK216249 DY-23CE/C UEG/A-4D-L/110V HZH-220VDC-1H-2H-1D DZJ-23 JGL-15A JZ-22H/51 JL-325H GL-25/5 JZY-220C JS14A DH48P SS-53 JSZ4A-A BS-62/I JY-141 DX-34B JZK-124T RXMS1 RK216038 DY-23C/60C UEG/A-3H1D-L/110V BS-113B HZH-220VAC-2H-2H-2D DZJ-222 JGL-14A JZ-22H/31 JL-325D GL-25 JZY-218 JS11S AJG-15 DH48L SS-47/I JSZ3C-E BS-141 BCH-2E JY-12A DX-34A JZK-115 RXMH2 DY-23B UEG/A-2H2D-L/110V HZH-220VAC-2H-1H1D-1D DZJ-221 JGL-13R/Ⅱ JZ-22H/11 JL-324H GL-24/10 JZY-214 JS11DN DH48J SS-342A JSZ3C-A BS-62/C JY-11 DX-34 BCD-51 JZK-112 RS-24VAC-3Z-10A DY-22E UEG/A-1H3D-L/110V HZH-220VAC-1H1D-1H1D-1D DZJ-220 JGL-13/Ⅱ JZ-21H/431J JL-324D GL-23/5 JZY-210 JS11-62 DH48 SS-322A JSZ3A-D JXZ9-C DX-33/5 JZJ-620 PTS3PR DY-22D SY-34/4 HZH-110VDC-2H-2H-1D DZJ-219X JGL-12A JZ-21H/250 JL-323H GL-23 JZY-206 JS-114C DH-3AE SS-29AF JSZ3 BS-62/ⅡC JX-UC4 DX-33/4 JZJ-402 MZJ DY-22CE SY-32/4 HZH-110VDC-1H-2H-1D DZJ-218X JGL-121 JZ-21E/61 JL-323D GL-22/10 JZY-202X JS11-41 DH-3A SS-23CE JSZ0C-E BS-140 ZZX-2 JX-UC1 DX-33/3 JZJ-225 MS4S-C DY-22C SY-23 HZH-110VAC-2H-2H-2D DZJ-217X JGL-11ST JZ-21/S21J JL-322J GL-21/5 找PT二次消谐就上：http://www.jdbhw.com/Products_Detial/11/114.html
