Jiapu cable qhia koj txog qhov ua rau muaj teeb meem hluav taws xob cable.Cable txhaum hom yuav muab faib ua grounding, luv Circuit Court, disconnection ntawm peb lub ntsiab pawg ntawm txhaum yog raws li nram no:
Ib theem ntawm cov tub ntxhais hlau tawg lossis ntau theem tawg hlau
Nyob rau hauv kev sim cable conductor kev twb kev txuas, cable conductor rwb thaiv tsev tsis kam thiab cov kev cai ntawm cov kab, tab sis nyob rau hauv lub view ntawm ib theem lossis ntau theem tsis tuaj yeem txuas nrog, tom qab ntawd ib theem ntawm cov tub ntxhais hlau tawg lossis ntau theem tawg.
Peb-core cable ib los yog ob tug tub ntxhais grounding
Peb-core cable core los yog ob tug tub ntxhais conductors nrog rwb thaiv tsev co lub rooj kuaj tawm ntawm qhov kev twb kev txuas, thiab ces ib tug tub ntxhais los yog ob tug tub ntxhais rau hauv av rwb thaiv tsev kuj telemetry.Yog hais tias cov tub ntxhais thiab cov tub ntxhais nyob nruab nrab ntawm lub neej ntawm rwb thaiv tsev tsis zoo tshaj qhov qub tus nqi qis dua tus nqi ntawm qhov rwb thaiv tsev no tus nqi siab tshaj 1000 ohms yog hu ua high resistance grounding txhaum;Conversely, yog ib tug tsis tshua muaj zog grounding txhaum.Ob qho kev txhaum no raug xa mus rau qhov tsis sib xws thiab hauv av.
Peb-theem tub ntxhais luv luv Circuit Court
Short-circuit grounding kuj loj yog lub cable ntawm peb-theem core short-circuit txhaum kev txheeb xyuas ntawm lub hauv paus.Muaj ob hom kev ua txhaum luv luv: tsis tshua muaj kev cuam tshuam luv luv-circuit txhaum, siab tiv thaiv luv-circuit txhaum.Thaum peb-theem tub ntxhais luv luv-circuit, tsawg dua 1000 ohms ntawm av tiv thaiv tsis tshua muaj kev tiv thaiv luv luv-circuit txhaum, ntawm qhov tsis sib xws, yog qhov ua haujlwm siab luv luv-circuit txhaum.
Kev soj ntsuam ua rau:
Ua ntej: kev puas tsuaj sab nraud
Cable teeb meem nyob rau hauv kev puas tsuaj rau sab nraud yog feem ntau ua rau muaj teeb meem.Lub cable raug puas los ntawm sab nraud quab yuam yav tom ntej yuav qhia qhov loj ntawm lub zog tsis ua haujlwm.Piv txwv li, cov txheej txheem kev tsim kho hauv av hauv av, cov kab hluav taws xob vim tias kev siv tshuab traction loj dhau thiab raug rub tawm;cable rwb thaiv tsev, shielding txheej vim kev khoov ntau dhau ntawm cov cable thiab kev puas tsuaj;cable txiav tev tawm ntau dhau txiav thiab riam cov cim tob dhau.Cov ntsiab lus ncaj qha sab nraud no yuav tsim kev puas tsuaj rau lub cable.
Thib ob: rwb thaiv tsev noo noo
Cable manufacturing txheej txheem tsis refined yuav ua rau lub cable tiv thaiv txheej tawg;cable terminal pob qij txha sealing tsis yog;cable tiv thaiv lub tes tsho nyob rau hauv lub cable siv los ntawm cov khoom pierced los yog tej zaum raug kev txom nyem corrosion.Cov no yog cov laj thawj tseem ceeb rau cov kab hluav taws xob rwb thaiv tsev noo noo.Tam sim no, cov rwb thaiv tsev tiv thaiv poob qis, qhov tam sim no nce, ua rau muaj teeb meem hluav taws xob.
Peb: chemical corrosion
Kev ua haujlwm ntev tam sim no yuav cia cov kab hluav taws xob rwb thaiv tsev tshwm sim ntau ntawm cov cua sov.Yog hais tias lub rwb thaiv tsev cable ua hauj lwm ntev ntev nyob rau hauv ib tug tsis zoo tshuaj ib puag ncig yuav hloov nws lub cev lub zog, thiaj li hais tias lub cable rwb thaiv tsev laus thiab txawm poob nyhuv, muaj teeb meem yuav tshwm sim.
Plaub: kev ua haujlwm ntev ntev
Cable ntev ua haujlwm siab tam sim no nyob rau hauv ib puag ncig, yog hais tias cov kab rwb thaiv tsev txheej muaj impurities los yog aging, ua ke nrog lwm yam xws li xob laim thiab lwm yam tshaj voltage cuam tshuam, overloading tshwm sim ntau ntawm tshav kub, nws yog heev yooj yim mus nthuav tawm teeb meem cable. .
