May 27, 2023
Teeb pom kev zoo rau cov nyiaj siv ua haujlwm cranes
Txhawm rau txhim kho kev ua haujlwm ntawm kev ua haujlwm ntawm tus choj crane, tus tsav tsheb cab thiab chav hluav taws xob ntawm tus choj crane yuav tsum tau nruab nrog cov khoom siv teeb pom kev zoo.
Cov khoom siv teeb pom kev zoo Crane hais txog cov teeb pom kev zoo uas tau teeb tsa rau ntawm cranes, feem ntau yog rau cov teeb pom kev zoo thiab muab kev ceeb toom nyob ib puag ncig thaj chaw uas crane nqa hnyav.
Teeb pom kev zoo rau cov khoom siv hluav taws xob crane teeb pom kev zoo
1. Cov kev xav tau ntawm cov khoom siv teeb pom kev zoo
Qhov hluav taws xob ntawm lub teeb pom kev ruaj khov tsis tshaj 220V, thiab qhov hluav taws xob ntawm lub teeb pom kev zoo tsis tshaj 36V. Tsis tas li ntawd, yuav tsum muaj ntau tshaj li ob lub qhov (socket) rau lub teeb pom kev zoo ntawm tus choj crane.
2. Cov khoom siv teeb pom kev hauv Circuit Court yuav tsum
Cov khoom siv teeb pom kev zoo thiab cov teeb liab ntawm cov choj cranes yog nruab nrog tshwj xeeb circuits. Thaum lub ntsiab Circuit Court breaker ntawm lub crane yog disconnected, lub teeb pom kev zoo thiab teeb liab circuits yuav tsum tau muab nrog luv luv-circuit tiv thaiv.
3. Cov khoom siv teeb pom kev zoo grounding device
Tag nrho cov khoom siv hluav taws xob, suav nrog cov kav hlau thiab ib sab ntawm lub teeb pom kev hloov pauv, yuav tsum muaj kev ntseeg siab hauv av.
4. Kev sib txuas hluav taws xob ntawm cov khoom siv teeb pom kev zoo
Yuav kom txiav txim siab, nyob rau hauv ib txwm muaj xwm txheej, yuav tsum muaj kev txhim khu kev qha hluav taws xob sib txuas ntawm lub log thiab kev khiav ntawm a20 tuj choj crane, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig ua hauj lwm hnyav, nws yog ib qho tsim nyog yuav tsum tau nce hauv av swb xaim lossis ua lwm yam kev ntsuas los txhim kho kev ntseeg tau hauv av.
Cov lus piav qhia ntawm cov teeb pom kev ruaj khov uas yuav tsum tau ua
Lub crane yuav tsum tau nruab nrog lub teeb pom kev sib cais, ib qho kawg ntawm 220v AC teeb pom kev zoo hluav taws xob yuav tsum tau ua hauv av, thiab lub zog loj hloov ntawm lub teeb pom kev zoo yuav tsum tau nruab nrog lub ntsuas hluav taws xob thiab kev tiv thaiv hluav taws xob. Nyob rau hauv tus neeg tsav tsheb lub tsheb, nws yog ib qho tsim nyog yuav tsum tau muab cov teeb pom kev ruaj khov thiab tsis muaj teeb pom kev zoo, uas yuav tsum tau npaj kom tsim nyog thiab muab teeb pom kev zoo txaus. Txawm hais tias lub ntsiab hluav taws xob hluav taws xob ntawm lub crane raug txiav tawm, lub teeb pom kev zoo yuav tsum tseem ua haujlwm.
Rau lub teeb pom kev zoo ntawm thaj chaw ua haujlwm, thaum lub teeb pom kev zoo ntawm qhov chaw ua haujlwm yog muab los ntawm crane, cov teeb pom kev zoo yuav tsum tau nruab rau ntawm qhov tsim nyog ntawm crane kom muaj qhov pom kev tsawg kawg nkaus ntawm 30lx hauv av. Cov teeb pom kev zoo yuav tsum tsis txhob poob siab, thiab lub teeb pom kev zoo yuav tsum tsis txhob raug tswj los ntawm lub ntsiab ntawm lub crane. Kev ceev faj yuav tsum tau coj los tiv thaiv kom tsis txhob muaj cov roj paug tawm ntawm qhov hluav taws xob vim qhov hluav taws xob poob vim qhov pib ntawm lub cev muaj zog.
Rau cov teeb pom kev zoo ntawm txoj kev hla thiab cov chav hluav taws xob, cov teeb pom kev zoo uas tsis tswj los ntawm cov kab tseem ceeb ntawm crane yuav tsum tau muab, thiab qhov tsawg kawg nkaus illuminance yog 30lx. Cov cranes yuav tsum tau nruab nrog lub teeb pom kev kub ceev. Thaum lub teeb pom kev ntawm qhov chaw tsis tuaj yeem ua kom muaj kev nyab xeeb ntawm lub crane, yuav tsum muaj teeb pom kev kub ceev nrog cov roj teeb, thiab cov roj teeb chargers yuav tsum muab rau hauv lub cab.
Raws li cov kev xav tau ntawm kev saib xyuas cov khoom siv hluav taws xob, lub teeb pom kev zoo yog tswj los ntawm lub ntsiab Circuit Court breaker, tsis yog tswj los ntawm lub ntsiab kev rho tawm thiab lub ntsiab fais fab contactor. Cov teeb pom kev ruaj khov thiab cov khoom siv teeb pom kev lag luam yuav tsum nyob twj ywm thaum lub ntsiab sib cais qhib. Lub ntsiab kev sib cais hloov kev sib raug zoo yog hais txog lub ntsiab kev rho tawm hauv lub ntsiab lub hwj chim faib lub thawv.
Kev piav qhia ntawm qhov system yuav tsum tau rau cov khoom siv teeb pom kev zoo txav tau
Rau qhov yooj yim ntawm kev saib xyuas, nws tuaj yeem teeb tsa nrog 36v kev nyab xeeb teeb pom kev zoo, thiab lub qhov hluav taws xob 36V tau teeb tsa ntawm qhov chaw. Lub qhov hluav taws xob sib txawv ntawm qhov sib txawv ntawm qhov sib txawv yuav tsum siv ntau hom lossis qhov ntau thiab tsawg ntawm cov qhov (sockets) kom tsis txhob muaj qhov sib txawv ntawm qhov sib txawv voltages; ob sab ntawm 36v kev nyab xeeb teeb pom kev zoo transformer yuav tsum tau grounded. Hom 36V fais fab socket yuav tsum tsis txhob muab tso rau hauv lub qhov (socket) ntawm lwm lub tshuab, thiab hom lub qhov (socket) yuav tsum tsis txhob muab tso rau hauv plugs ntawm lwm lub tshuab.
Cov20 tuj choj nyiaj siv ua haujlwm craneyuav tsum muaj tsawg kawg yog 2 qhov rau ntsaws rau hauv lub teeb pom kev zoo, thiab lub zog hluav taws xob ntawm lub teeb pom kev zoo yuav tsum tsis pub tshaj 36V. Lub 36V nyob ib feem ntawm lub teeb pom kev zoo yuav tsum raug cais tawm ntawm hluav taws xob thiab lub cev sib cais los ntawm lwm lub voj voog lossis hauv av, uas yog, 36V nyob ib feem ntawm lub teeb pom kev zoo tsis yog hauv av, thiab cov xov hlau ntawm 36V nyob ib sab yog them nrog cov uas tsis yog- lub tes tsho hlau tshwj tsis yog rau kev rwb thaiv tsev yooj yim. cev lay. Cov conductors ntawm qhov sib txawv voltages yog sib cais los ntawm ib tug grounded hlau ntaub thaiv npog los yog sheath. Rau qhov nyob ntawm 36V, insulated conductors nrog qhov ntsuas hluav taws xob ntawm AC 500v rau 1min yuav tsum tau siv, los yog cov ntaub thaiv npog lossis cov ntaub thaiv npog sab nrauv nrog qib tiv thaiv tsawg kawg IPXXB kom ua tiav kev tiv thaiv kev tiv thaiv.
