Nws zoo dua, wireless kub ntsuas los yog faib fiber optic kub sensor rau substations

Fiber optic kub sensor, Ntse xyuas lawv, Distributed fiber optic manufacturer nyob Suav teb

Ib substation yog ib lub hwj huam chaw nyob rau hauv lub hwj huam uas converts voltage, tau txais thiab faib hluav taws xob zog, tswj cov hluav taws xob, thiab kho kom haum. Ua ib qho tseem ceeb heev conversion puag, Yog hais tias hluav taws kub los yog lwm yam hwj huam sib tsoo tshwm sim nyob rau hauv ib substation, Nws yuav inevitably ua rau loj-teev fais fab tuag, Yuav ua tau tej yam tseem ceeb thiab losses rau qhov ntau lawm enterprises thiab lub neej ntawm cov neeg. Yog li ntawd, vim, Xyuas kom muaj kev ruaj ntseg thiab reliability ntawm substations thiab tsis txhob hluav taws kub tseem ceeb heev. Ntawm lawv, Khoom overheating yog ib qho tseem ceeb nkaum uas yuav ua rau substation hluav taws kub. Overheating ntawm lub dynamic thiab static hu thiab lwm yam kev sib txuas ntawm high-voltage switchgear hauv substations, cable joints, cable sib txuas, thiab ib feem ntawm high-voltage cables yog lub ntsiab nkaum phom sij ntawm cov kev huam yuaj loj-teev kev huam yuaj. ntxiv thiab, Cov chaw no feem ntau muaj voltages ntau txhiab los yog txawm kaum tawm txhiab tus volts, posing zoo kawg thiab kev nyab xeeb rau cov tswv nkag mus thiab soj ntsuam.

Characteristics and Disadvantages of Wireless Temperature Measurement System in Substation

Wireless kub sensor, wireless centralized receiver, substation xyuas, centralized chaw nres tsheb yam lig, tej thaj chaw deb, Tus wireless kub sensor yog txuas nrog lub wireless centralized receiver los ntawm wireless sib txuas lus; Tus wireless centralized receiver yog txuas nrog rau lub substation xyuas los ntawm wired sib txuas lus; Substation xyuas thiab centralized tswj chaw nres tsheb yam lig; Sib txuas ntawm tej thaj chaw deb xyuas qhov chaw thiab centralized tswj chaw nres tsheb; Tus substation xyuas configuration yog nruab nrog ib GSM network uas yuav ua rau muaj peevxwm anomaly tswb yuav muab xa mus rau cov neeg ua hauj lwm mobile tes; Tej thaj chaw deb xyuas qhov chaw, centralized chaw nres tsheb yam lig, thiab substation xyuas yog txhua nruab nrog kub xyuas zaub li, uas saib xyuas qhov kub ntawm cov khoom substation nyob rau lub sij hawm tiag. Tus substation xyuas muaj ib tug kub harbor, Uas yuav piv tau cov ntaub ntawv kub nrog cov preset Harbor thiab xa abnormal tswb tswb rau cov neeg ua hauj lwm mobile tes kom passively teev ib kub Harbor. Nws tsis tau teev tej alarms ntau raws li qhov chaw. Yog hais tias muaj ntau qhov txawv hauv qhov kub ntawm ntau cov ntsiab lus nyob rau hauv cov substation, Lub kaw lus yog prone rau misjudgment, thiab txawm tias hluav taws kub loj yuav tshwm sim thaum lub tswb yog triggered. Tsis tau yog nyob rau qhov chaw ntawm cov kev huam yuaj taw tes, Tsuas txiav txim seb qhov hluav taws kub tswb, thiab tsis muaj kev cuam tshuam qhov teeb meem no tiag.

Kom zoo dua Distributed Fiber Optic kub ntsuas lawv hauv substation

Vim nws muaj peev xwm mus cuag distributed continuous xyuas kub raws tus fiber optic cable, thiab nws kom zoo dua xws li me me, luj, hluav taws xob insulation, tshuaj corrosion kuj, kub muaj peevxwm, rhiab, teb ceev, tawg-profo, nplaim-retardant, nqi tsawg, thiab kuj ua electromagnetic interference, distributed fiber optic temperature sensors have been widely used in pipeline leak detection, ua kom mob, lub hwj huam xyuas, ceeb toom hluav taws, thiab kev kho mob.

FJINNO muab ib qho optical fiber kub ntsuas lawv substation kub xyuas. Siv distributed optical fiber kub kuaj raws li Raman scattering kub ntsuas tshuab, Muaj peevxwm anomalies yuav yog thiab lub sij hawm nyob rau ib optical fiber ntau; Tib lub sijhawm, Lawv yog nruab nrog txuj kev kub-theem kub tswb qhov tseem ceeb thiab kub sawv tswb tswb, displaying kub tis curves nyob rau lub sij hawm tiag, thiab muab lus ceeb toom thaum ntxov ua ntej hluav taws kub tshwm sim. Qhov no daws tau qhov teeb meem uas twb muaj lawm kub ntsuas lub nruab yuav tsuas passively teev ib kub Harbor, Uas yog prone rau misjudgment thiab tsis tau yog nyob rau qhov chaw ntawm cov kev huam yuaj taw tes. Thaum tam sim no, Muaj ntau kev tshawb fawb rau distributed fiber optic kub ntsuas tshuab raws li Raman scattering nyob hauv tsev thiab sia mus thoob ntiajteb. Lub hauv paus rau achieving distributed ntsuas ntawm kub raws tus fiber optic cable yog cov Raman scattering thiab optical sij hawm domain reflection tshuab generated thaum teeb propagates hauv lub fiber optic cable. Thaum teeb undergoes Raman scattering hauv lub fiber optic cable, Nws lub teeb scattered intensity yog hais txog qhov kub, Li ntawd, intensity modulation tshuab yuav siv tau los ntsuas qhov kub raws tus fiber optic cable; Yog siv sij hawm optical sij hawm domain reflection tshuab, Tus demodulation ntawm txoj hauj lwm ntawm qhov ntsuas kub yuav tiav, Li no ua tiav cov distributed ntsuas ntawm kub raws tus fiber optic cable.
