Muaj nuj nqi thiab muaj pes tsawg leeg ntawm hluav taws xob tswj system

ua haujlwm loj

Txhawm rau kom ntseeg tau tias muaj kev ntseeg siab thiab kev nyab xeeb ntawm cov cuab yeej tseem ceeb, ntau yam khoom siv hluav taws xob yuav tsum tau ua haujlwm rau nws. Kev sib xyaw ua ke ntawm ob peb yam khoom siv hluav taws xob uas tuaj yeem ua tiav qee yam kev tswj hwm yog hu ua tswj Circuit Court lossis theem ob. Cov khoom siv no yuav tsum muaj cov haujlwm hauv qab no:

(1) Tsis siv neeg tswj kev ua haujlwm. High voltage thiab high tam sim no switchgear muaj ib tug loj ntim thiab feem ntau yog siv los tswj lub qhib thiab kaw ntawm kev khiav hauj lwm systems. Tshwj xeeb tshaj yog thaum cov cuab yeej ua haujlwm tsis zoo, nws yuav tsum tau txiav tawm hauv Circuit Court kom muaj cov txheej txheem tswj tsis siv neeg cov khoom siv hluav taws xob ua haujlwm thiab cov khoom siv hluav taws xob rau kev tswj tsis siv neeg.

(2) Kev tiv thaiv muaj nuj nqi. Cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob tuaj yeem ua haujlwm tsis zoo thaum lub sijhawm ua haujlwm, nrog rau qhov tam sim no (lossis qhov hluav taws xob) dhau qhov kev tso cai ua haujlwm thiab txwv ntawm cov khoom siv thiab cov khoom siv hluav taws xob. Qhov no yuav tsum muaj cov cuab yeej tiv thaiv txhawm rau txhawm rau txheeb xyuas cov teeb meem txhaum cai no thiab hloov kho (disconnect, hloov, thiab lwm yam) cov cuab yeej thiab cov khoom siv hluav taws xob.

(3) Saib xyuas qhov system ua haujlwm. Hluav taws xob tsis pom ntawm lub qhov muag, thiab nws tsis tuaj yeem paub qhov txawv ntawm lub tshuab hluav taws xob los yog tawm ntawm nws qhov tsos. Qhov no xav kom cov tuam txhab teeb tsa ntau lub network audiovisual signals, xws li teeb thiab suab tshuab, los tshuaj xyuas thiab saib xyuas cov ntaub ntawv hluav taws xob ntawm lub cuab yeej.

(4) Kev ntsuas kev ua haujlwm. Lub teeb thiab lub suab teeb liab tsuas tuaj yeem ua rau pom qhov ua haujlwm ntawm lub cuab yeej (nrog lossis tsis muaj hluav taws xob). Yog tias peb xav kom nkag siab ntau ntxiv txog kev ua haujlwm ntawm cov khoom siv hluav taws xob, peb xav tau ntau yam cuab yeej los ntsuas qhov tsis sib xws ntawm cov khoom siv thiab cov circuits, xws li voltage, tam sim no, zaus, thiab lub zog.

Hauv kev ua haujlwm thiab kev saib xyuas cov cuab yeej siv, cov khoom siv ua haujlwm ib txwm siv, cov khoom siv tswj, cov cuab yeej, thiab cov teeb liab tuaj yeem hloov tau los ntawm kev tswj hwm lub khoos phis tawj thiab cov khoom siv hluav taws xob, tab sis tseem muaj qee yam kev siv hauv cov khoom siv me me thiab kev tswj xyuas hauv zos. Qhov no kuj yog lub hauv paus rau kev siv microcomputer tsis siv neeg tswj hauv circuits.

qhov system muaj pes tsawg leeg

Lub hauv paus Circuit Court ntawm feem ntau siv tswj circuits muaj cov hauv qab no.

(1) Fais fab mov Circuit Court. Lub zog hluav taws xob ntawm lub zog hluav taws xob muaj xws li AC380V thiab 220V, thiab lwm yam.

(2) Tiv thaiv lub voj voog tswj. Cov khoom siv hluav taws xob tiv thaiv (auxiliary) circuits suav nrog ntau hom xws li ib-theem 220, 36V lossis DC 220, 24V, thiab lwm yam. Nws txheeb xyuas cov khoom siv hluav taws xob engineering thiab kab xov xwm rau ntau yam kev tiv thaiv ib puag ncig xws li luv luv Circuit Court, overloads, thiab voltage poob. . Nws tsuas yog muaj kev tiv thaiv thiab tswj cov khoom xws li fuses, thermal relays, voltage poob coils, rectification system Cheebtsam, thiab voltage stabilization Circuit Court Cheebtsam.

(3) Lub teeb liab tswj Circuit Court. Ib lub voj voog uas tuaj yeem cuam tshuam tam sim lossis tso saib cov ntaub ntawv cov ntaub ntawv ntawm kev ua haujlwm ib txwm ua thiab txawv txav thiab kev ua neej nyob ntawm cov cuab yeej siv thiab cov khoom siv hluav taws xob, xws li teeb liab teeb ntawm cov xim sib txawv, cov khoom siv suab nrog cov suab sib txawv, thiab lwm yam.

(4) Tsis siv neeg thiab phau ntawv circuits. Txhawm rau txhim kho kev ua haujlwm ntawm cov khoom siv hluav taws xob, kev sib txuas tsis siv neeg feem ntau yog siv. Txawm li cas los xij, thaum lub sijhawm teeb tsa, kev debugging, thiab xwm txheej xwm txheej ceev, kev sib txuas ntawm phau ntawv yuav tsum tau teeb tsa hauv kev tswj xyuas hluav taws xob kom hloov ntawm hom tsis siv neeg thiab phau ntawv los ntawm cov keyboards lossis kev sib txuas ntawm cov keyboards.

(5) Nres nres Circuit Court. Txiav tawm lub zog hluav taws xob ntawm lub voj voog, siv kev ntsuas braking xws li kev siv lub zog nres, lub zog rov qab nres, rov qab braking, regenerative braking, thiab lwm yam, kom ceev ceev nres lub cev muaj zog.

(6) Kev ntsuas tus kheej thiab ntsuas qhov ntsuas hluav taws xob. Tom qab lub pob pib raug tso tawm, lub voj voog tseem muaj zog, thiab cov khoom siv hluav taws xob uas tuaj yeem ua haujlwm txuas ntxiv yog hu ua tus kheej-locking tivthaiv, xws li kev txav mus los ntawm tus contactor txuas nrog hauv series hauv coil circuit. Ob lossis ntau dua cov khoom siv hluav taws xob thiab cov khoom siv, txhawm rau ua kom muaj kev nyab xeeb thiab txhim khu kev lag luam ntawm cov khoom siv, tsuas yog muaj ib qho uas tuaj yeem pib nrog hluav taws xob thiab lwm yam uas tsis tuaj yeem pib nrog hluav taws xob, uas yog hu ua qhov txuas txuas. Piv txwv li, dynamic breaking hu ntawm ob contactors yog txuas nrog nyob rau hauv series nyob rau hauv opposite coil circuits.
