Installation Notes ntawm 250KW Yuchai Genset thiab UPS

Ua ntej, peb yuav tsum nkag siab txog cov ntaub ntawv thauj khoom ntau npaum li qhov ua tau, thiab ntawm lub hauv paus no, tsim nyog nthuav tawm lub zog ntawm lub tshuab hluav taws xob teeb tsa.Raws li qhov kev xav no, nws yuav muaj txiaj ntsig zoo dua rau lub tshuab hluav taws xob teeb tsa kom ncav cuag 60% ~ 80% load tus nqi kom deb li deb tau.

Sim xaiv lub tshuab hluav taws xob nrog cov zis impedance tsawg thiab muaj peev xwm teb tau zoo;Nws raug nquahu kom siv hom kev cuam tshuam tsawg dua los ntawm kev sib haum xeeb, xws li PMG lub tshuab hluav taws xob ruaj khov.

Rau AVR generator voltage nrhiav kom tau, nws raug nquahu kom siv peb-theem nrhiav kom tau qhov nruab nrab tus nqi es tsis txhob ntawm ib-theem nrhiav kom tau, txhawm rau txhim kho qhov ruaj khov ntawm qhov ntsuas hluav taws xob thiab txo qhov cuam tshuam ntawm qhov hloov pauv ntawm lub tshuab hluav taws xob.Lub tshuab hluav taws xob teeb nrog ntau hom kev ua haujlwm muaj cov teebmeem uas tsis yog-linear.Lub peev xwm thauj khoom kuj yuav txawv.Piv txwv li, ob-stroke diesel generator teeb yog zoo dua li plaub stroke diesel generator teeb.Nws yuav tsum tau muab sau tseg tias yog hais tias tus parameter teeb ntawm generator teeb controller yog tsis raug, nws kuj yuav ua rau mismatch nrog UPS.Thaum lub sij hawm UPS commissioning, yog hais tias tus nqi ntawm lub tshuab hluav taws xob chav tsev voltage thiab zaus txee tau pom tias tsis ruaj khov, kom txo tau qhov rhiab heev pob qhov rooj ntawm AVR yuav daws tau qhov teeb meem.

Txhawm rau tiv thaiv AC cuam tshuam cov teeb liab los ntawm kev cuam tshuam rau kev ua haujlwm ntawm lub cav hluav taws xob hluav taws xob, tus tswv xeev vaj tse yuav tsum tau ua kom zoo hauv av thiab kev tiv thaiv zoo yuav tsum tau ua rau lub teeb pom kev nrawm.Nws raug pom zoo tias lub tshuab hluav taws xob teeb yuav raug them maj mam thiab ua ntu zus.Nyob rau hauv txoj cai, hnyav load pib ua ntej thiab lub teeb load pib tom qab.

Qhov thib ob, lub zog nquag xa tawm los ntawm lub tshuab hluav taws xob teeb tsa nyob ntawm lub zog ntawm lub cav, thiab lub zog pom tseeb feem ntau yog nyob ntawm lub peev xwm ntawm lub tshuab hluav taws xob.Yog li ntawd, thaum lub generator teeb yog nruab nrog nonlinear loads xws li inverter, tsuas yog lub peev xwm ntawm lub tshuab hluav taws xob yuav tsum tau nce, thiab nws cov yam ntxwv ntawm transient yuav zoo dua, thaum cov zis active zog ntawm pab pawg n tsis nce kev xyaum tau ua pov thawj tias. Nws yog ib qho ua tau kom daws tau qhov teeb meem sib txuam ntawm inverter thiab lub tshuab hluav taws xob teeb tsa los ntawm kev siv lub tsheb rub lub tsheb, thiab nws tuaj yeem txuag tau qee tus nqi rau cov neeg siv, thiab kev nqis peev kuj tseem ceeb heev.

Thirdly, xaiv lub inverter tsim nyog rau cov yam ntxwv ntawm lub tshuab hluav taws xob teeb, lub inverter nrog ntau zog input zog thiab qis dua tam sim no harmonic yuav tsum tau xaiv.Rau cov lim dej, sab nkag ntawm UPS yog capacitive thaum UPS tsis muaj load lossis lub teeb load.Cov yam ntxwv, nws raug pom zoo kom xaiv cov hom lag luam uas tuaj yeem muab cov phiaj xwm kev txhim kho thiab kev ua kom zoo.Yog hais tias lub inverter muaj lub zog thiab cov yam ntxwv ntawm high-speed broadband rectifier tswj Circuit Court, bypass voltage, zaus tiv thaiv ntau yam, on-site adjustable inverter synchronization tus nqi, qeeb pib fais fab mus rau hauv, rectifier qeeb pib, ntse generator hom, thiab lwm yam. tuaj yeem ua kom zoo dua ntawm lub tshuab hluav taws xob teeb.

Plaub, nyob rau hauv tsawg-voltage tis, cov yam ntxwv ntawm inductive load thiab capacitive load yuav siv tau kom lub inductive fais fab tuag ntawm tag nrho cov load ntawm txog 0.9 li deb li deb tau;Tsis siv neeg hloov khoom siv, uas tuaj yeem txuas inductive loads xws li cua txias rau pem hauv ntej ntawm inverter.

Lub sijhawm hloov pauv tsis siv neeg ntawm ATS yog staggered los tiv thaiv tag nrho cov loads los ntawm kev pib nyob rau tib lub sij hawm thaum lub mains fais fab tuag, ua rau cov zis ntau heev fluctuation ntawm lub generator teeb los yog tiv thaiv kaw;Tsis txhob reactive zog them nyiaj ntawm lub tshuab hluav taws xob teeb;Mature thiab txhim khu kev qha cov nyiaj regulators yog siv rau inductive, capacitive reactive zog them thiab harmonic tswj nyob rau hauv lub hwj chim system.

1. Lub chaw teeb tsa yuav tsum muaj qhov cua zoo, nrog cov cua nkag txaus ntawm lub tshuab hluav taws xob kawg thiab qhov hluav taws xob zoo ntawm lub cav diesel kawg.Qhov chaw ntawm lub qhov hluav taws xob yuav tsum yog ntau tshaj 1.5 npaug ntawm lub tank dej.

2. Qhov chaw nyob ib puag ncig ntawm qhov chaw teeb tsa yuav tsum tau ua kom huv si kom tsis txhob tso ib yam dab tsi uas yuav tsim cov roj thiab roj.Yog tias muaj kev tso cai, cov khoom siv tua hluav taws yuav tsum tau muab.

3. Thaum siv sab hauv tsev, cov yeeb nkab yuav tsum txuas nrog rau sab nraud.Txoj kab uas hla ntawm cov yeeb nkab yuav tsum ntau dua los yog sib npaug ntawm txoj kab uas hla ntawm cov kav dej muffler.Tus naj npawb ntawm cov yeeb nkab luj tshib yuav tsum tsis pub tshaj 3 kom ntseeg tau tias cov pa tawm tau zoo.Cov yeeb nkab yuav tsum tau txuas nrog ib qho inclination ntawm 5 mus rau 10 degrees kom tsis txhob txhaj dej nag.Yog hais tias cov yeeb nkab tso tawm yog ntsia vertically upward, ib tug rainproof ntaus ntawv yuav tsum tau ntsia.

4. Thaum siv cov pob zeb ua lub hauv paus, qhov flatness ntawm chav tsev yuav tsum tau ntsuas nrog lub ntsuas ntsuas thaum lub sij hawm teeb tsa los txhim kho chav nyob ntawm lub hauv paus kab rov tav.Yuav tsum muaj qhov tshwj xeeb shockproof ncoo los yog thauj tog rau nkoj ntsia liaj qhov rooj ntawm chav tsev thiab lub hauv paus.

5. Lub plhaub chav tsev yuav tsum muaj kev ntseeg siab hauv av.Rau lub tshuab hluav taws xob uas yuav tsum tau ncaj qha hauv av nrog nruab nrab taw tes, qhov nruab nrab ntawm qhov nruab nrab yuav tsum yog hauv av los ntawm cov neeg ua haujlwm tshaj lij thiab nruab nrog cov cuab yeej tiv thaiv xob laim.Nws yog txwv tsis pub tsav lub nruab nrab taw tes nrog lub mains grounding device.Kev tsaws ncaj qha.

6. Ob txoj kev hloov ntawm lub tshuab hluav taws xob thiab lub zog hluav taws xob yuav tsum muaj kev ntseeg siab heev los tiv thaiv kev xa hluav taws xob rov qab.Kev ntseeg siab ntawm ob txoj kev hloov hluav taws xob yuav tsum tau kuaj xyuas thiab pom zoo los ntawm lub tuam txhab hluav taws xob hauv zos.
