JS-103A 時(shí)間繼電器產(chǎn)品概述 用于發(fā)電機(jī)、變壓器及輸電線路的過(guò)負(fù)荷和短路的繼電保護(hù)回路中。 JS-103A 時(shí)間繼電器工作原理 繼電器是根據(jù)電磁原理工作的。當(dāng)電磁鐵線圈流過(guò)規(guī)定數(shù)值的電流時(shí)，動(dòng)片克服反作用力矩而趨向磁極，使觸點(diǎn)閉合。當(dāng)電流消失或電流降低至返回值時(shí)，可動(dòng)系統(tǒng)返回原始位置，觸點(diǎn)斷開(kāi)。為了消除發(fā)電機(jī)外部發(fā)生故障時(shí)所出現(xiàn)的高次諧波（特別是三次諧波）對(duì)繼電器的影響，即防止繼電器在此時(shí)產(chǎn)生誤動(dòng)作，所以在線圈的二次繞組中，并聯(lián)一個(gè)電容器組成三次諧波濾過(guò)器。繼電器動(dòng)作電流的整定值通過(guò)轉(zhuǎn)動(dòng)刻度盤(pán)上的指針、改變游絲的作用力矩來(lái)達(dá)到。 JS-103A 時(shí)間繼電器相關(guān)型號(hào) ST3PC-F DZB-254 AJG-15 BT-1B/901B/R DZY-211X HY-22D JDZL-1220 JZ17-80 HJZ-Y901 JL-312G BS-135B JZY-002B JLK-12 SRTT-24VDC-4H-A DSJ-11E JSS20-31AM ZJY-620 JXC-UB8 JZJ-212X LY-61 ST3PA-F DZB-249 BS-71C/Ⅱ BT-1B/90 DZY-210X HY-21A JDZL-1020 JZ16-22J HJZS-E002 JL-312C JZS-600/3 JLK-10C SRTT-220VDC-4H-AB DSJ-11 JSS20-11 ZJY-260 JXC-UB2 BS-165B/C BS-172B JZJ-208X LY-53B SSJ8-32E DZB-248 BT-1B/2001B/R DZY-209X HY-11D BS-112B JDZ2-S32 JZ15-80J HJZS-97 JL-311I JZS-333/220B JL-8-33 SRTT-220VAC-4H-C DSJ-10E JSS1P1-06/M ZJY-040 JXC-UA4 JZJ-204X LY-51B SSJ8-31C DZB-244 BS-71C/Ⅰ BT-1B/200 DZY-208X HSS20-31AM JDZ2-S12 JZ15-26Z HJZS-93 JL-311E JZS3-300A JL8-32 SRTT-110VDC-4H-C DSJ-10 JSS-17 ZJX-2 JXC-IC3 BS-172A/C JZJ-200X LY-33 SSJ8-22C DZB-243 BT-1B/1B/R DZY-207X HSL-23 JDZ-2C JZ14-62Z HJZ-J924 JL-311A BS-135A/C JZS-312/400 JL-83 SRTT-110VDC-2H2D-A DS-38C/X JSS1-40W ZJS-220/7 JXC-IB5 BFL-2E JZJ1-1 LY-20 SSJ8-21A DZB-236 BS-71C BT-1B/1601B/R DZY-206X HSL-15 JDZ2-62 JZ1-42 HJZ-J922 JL3 JZS-254 JL-8-22A SRTT-110VAC-2H2D-B DS-38C/2X JSS1-30D ZJL-620 JXC-IA6 BS-165B BS-172A JZJ-002 LNG-2 SSJ8-12A DZB-233 BT-1B/160 DZY-205X HSL-11 JDZ2-30K JZ1-21 HJZ-J920 JL-25-43C JZS-240X JL-8-21 SRTST-220VDC-2H-2H-C DS-38C/2 JSS1-20D ZJL-260 JXC-IA2 JZFY-11 LL-7A/2 SSJ-79T2 DZB-229 BS-71B/ⅡC BT-1B/1301B/R DZY-204X HS23-61 JDZ-1C JZ11-80JP HJZ-J918 JL-25-42B JZS-230X JL-8-13 SRTST-220VAC-1H1D-1H1D-A DS-38C JSS1-10M ZJL-006 JX-9C BS-172 JZB-600/9 LL-62B SSJ-79C/T2 DZB-228 BT-1B/130 DZY-203X HS23-51 JDZ1-62 JZ11-44ZP HJZ-J916 JL-25-41A BS-135A JZS-228/T JL8-12 SRTST-110VAC-1H1D-1H1D-B DS-38/X JSS1-10D ZJJ-422 JX-8-U-31 JZB-402/8 LL-5C SSJ-79B/T2 DZB-226 BS-71B/Ⅱ BT-1B/1201B/R DZY-202X HS23-41 JDZ1-30K JZ11-26JS HJZ-J914 JL-23B JZS-226 JL-81 SRTSD-110VDC-2H-2H DS-38/C JSS1-09E/M ZJJ-240 JX-8-U-21 BS-165A/C BS-171B/C JZB-338/220 LL-14E SSJ-79AD 找站用變保護(hù)測(cè)控裝置就上：http://www.jdbhw.com/Products_Detial/8/111.html
