Dab tsi yog Kev Ua Haujlwm ntawm Buchholz Relay hauv Fais Fab Transformer
Fais fab transformers yog ib qho tseem ceeb ntawm cov hluav taws xob tsim hluav taws xob thiab kev faib khoom. Lawv tau tsim los hloov siab voltage, tsis tshua muaj hluav taws xob tam sim no mus rau qhov tsis tshua muaj hluav taws xob, hluav taws xob siab tam sim no, thiab lwm yam. Txawm li cas los xij, kev nyab xeeb thiab ua haujlwm tau zoo ntawm cov hluav taws xob hloov hluav taws xob yog qhov tseem ceeb los xyuas kom meej lub zog txuas ntxiv. Txhawm rau ua tiav qhov no, ntau yam khoom siv tiv thaiv tau ua haujlwm, suav nrog Buchholz relay.
Yog li dab tsi yog Buchholz relay, thiab dab tsi yog nws txoj haujlwm hauv lub zog hloov hluav taws xob? Buchholz relay yog ib qho khoom siv tiv thaiv uas feem ntau pom thiab ceeb toom cov neeg ua haujlwm ntawm txhua yam teeb meem sab hauv hauv lub tank transformer. Nws yog lub npe hu ua tom qab nws inventor, Max Buchholz, German hluav taws xob engineer uas tsim nws nyob rau hauv 1921.
Lub Buchholz relay yog ntsia nruab nrab ntawm lub transformer tank thiab nws cov roj conservator. Nws ua haujlwm ntawm lub hauv paus ntsiab lus ntawm kev tshawb nrhiav roj. Thaum cov roj transformer decomposes vim lub ntuj aging los yog raws li ib tug tshwm sim ntawm ib tug txhaum, roj yog tsim uas accumulates nyob rau hauv lub transformer tank. Yog tias qhov ntim ntawm cov pa nce mus txog qhov tseem ceeb, nws tshem cov roj thiab tsim ib qho chaw uas cov huab cua thiab cov pa sib tov tuaj yeem tsim. Qhov no ua rau muaj qhov sib txawv ntawm qhov sib txawv ntawm lub tank transformer thiab roj conservator, uas ua rau Buchholz relay mus ncig.
Lub Buchholz relay muaj xws li ib tug roj sau chamber, ib tug ntab mus, thiab ib tug tiv tauj system. Thaum cov roj concentration nyob rau hauv lub tank transformer tshaj li ib txwm theem, lub ntab hloov mus rau pem hauv ntej, kaw qhov kev sib cuag system thiab tripping lub tswb, uas ceeb toom rau tus neeg teb xov tooj.
Lub luag haujlwm tseem ceeb ntawm Buchholz relay yog txhawm rau txheeb xyuas qhov tsis raug thaum ntxov ua ntej lub tshuab hluav taws xob raug puas tsuaj loj. Nws pab txo qis qhov kev puas tsuaj, khaws cov nqi kho kom zoo, thiab zam kom tsis txhob muaj teeb meem. Qee qhov txhaum cai uas Buchholz relay tuaj yeem kuaj pom muaj xws li hluav taws xob faults, rwb thaiv tsev faults, thiab xoob kev sib txuas hauv transformer.
Nyob rau hauv cov ntsiab lus, Buchholz relay yog ib qho tseem ceeb tiv thaiv ntaus ntawv nyob rau hauv lub hwj chim transformers. Nws lub luag haujlwm tseem ceeb yog txhawm rau txheeb xyuas cov teeb meem sab hauv hauv lub tank transformer thiab ceeb toom cov neeg ua haujlwm tam sim kom ua qhov tsim nyog. Kev siv Buchholz relay tuaj yeem pab tiv thaiv kev puas tsuaj loj, txo kev puas tsuaj thiab txo tus nqi kho, thiab ua kom lub zog txuas ntxiv.
