Lub Npe: Qhov tseem ceeb ntawm cov khoom siv tiv thaiv xob laim hauv kev tiv thaiv xob laim

Nce siabcov neeg ntes, tseem hu ua surgecov neeg ntes, yog ib feem tseem ceeb ntawm txhua lub tshuab tiv thaiv xob laim. Xob laim tuaj yeem ua rau muaj kev puas tsuaj loj heev thiab ua rau tuag taus, yog li kev sivcov khoom siv tiv thaiv xob laimyog qhov tseem ceeb kom txo qhov cuam tshuam ntawm xob laim. Hauv tsab blog no, peb yuav tham txog qhov tseem ceeb ntawm cov khoom siv tiv thaiv hluav taws xob hauv kev tiv thaiv xob laim, thaum tseem tshawb nrhiav cov khoom uas ua rau cov khoom siv tiv thaiv hluav taws xob zoo.

Ib qho ntawm cov khoom tseem ceeb ntawm lub cuab yeej ntes zoo yog cov rwb thaiv tsev EPDM uas kho tau los ntawm sulfur uas siv rau hauv nws txoj kev tsim kho. Xob laim tsim cov hluav taws xob siab uas tuaj yeem ua rau cov khoom siv uas kov nws puas tsuaj. Cov rwb thaiv tsev EPDM pab tiv thaiv cov khoom siv ntes los ntawm kev muab ib qho thaiv ntawm cov hluav taws xob siab thiab cov khoom sab hauv ntawm lub cuab yeej ntes.

Lwm yam tseem ceeb ntawm cov khoom siv tiv thaiv hluav taws xob yog lawv cov khoom siv tiv thaiv semiconductor. Cov khoom siv tiv thaiv no kuj pab tiv thaiv cov khoom siv tiv thaiv hluav taws xob ntawm cov hluav taws xob siab, vim nws muab txoj hauv kev rau lub zog ntau dhau los pov rau hauv av. Tsis tas li ntawd, lub khau raj EPDM semi-conductive molded ua tau raws li qhov yuav tsum tau ua ntawm ANSI / IEEE Standard 592, kom ntseeg tau tias nws muab kev tiv thaiv zoo tshaj plaws.

Lub arrester core yog lwm qhov tseem ceeb ntawm lub arrester zoo. Lub core muaj lub phaj zinc oxide surge arrester uas tau kho nrog cov txheej txheem tshwj xeeb, ua rau nws zoo heev rau kev tswj hwm cov hluav taws xob surges. Lub arrester core yog lub luag haujlwm los tiv thaiv kev puas tsuaj hluav taws xob rau cov khoom siv los ntawm kev hloov cov hluav taws xob ntau dhau mus rau hauv av.

Cov khoom siv tiv thaiv hluav taws xob kuj muaj cov probes uas muab txoj kev coj hluav taws xob zoo thiab sib txuas cov poj niam sib txuas. Cov probes siv los tiv thaiv kev flashovers ntawm cov khoom siv sib txuas. Tsis tas li ntawd, cov xov hlau grounding tuab tuaj yeem siv los kos lub zog hluav taws xob zoo tom qab mus txog qhov chaw grounding, txo qhov feem pua ​​​​​​ntawm kev puas tsuaj ntawm cov khoom siv.

Nws yog ib qho tsim nyog sau tseg tias lub cuab yeej ntes hluav taws xob yuav tsum tau teeb tsa rau hauv ib qho chaw tsim nyog thiab ceev faj thaum siv nws. Lub cuab yeej ntes hluav taws xob yuav tsum tau muaj av txaus thiab teeb tsa rau hauv qhov chaw uas yooj yim nkag mus rau kev saib xyuas. Tsis tas li ntawd, lawv yuav tsum tau kuaj xyuas tsis tu ncua kom paub tseeb tias lawv ua haujlwm zoo.

Hauv ntej, lub cuab yeej tiv thaiv xob laim yog ib feem tseem ceeb ntawm lub tshuab tiv thaiv xob laim. Ntxiv rau kev tiv thaiv xob laim, lawv siv kuj tseem ceeb heev rau kev txo qhov puas tsuaj ntawm cov khoom siv thiab tiv thaiv kev poob cov ntaub ntawv vim muaj hluav taws xob ntau dhau. Kev nkag siab txog lub luag haujlwm ntawm txhua yam khoom ntawm lub cuab yeej tiv thaiv xob laim yog qhov tseem ceeb rau kev txiav txim siab seb yuav siv hom cuab yeej tiv thaiv xob laim twg. Nrog lub cuab yeej tiv thaiv xob laim zoo thiab kev teeb tsa thiab kev saib xyuas kom zoo, cov lag luam tuaj yeem so kom yooj yim paub tias lawv tau tiv thaiv zoo los ntawm txhua yam kev cuam tshuam tsis zoo los ntawm xob laim.
