Countermeasures Tom qab Kev Tawm Haujlwm

Yog hais tias lub rwb thaiv tsev ntawm lub tshuab hluav taws xob excitation 1PT siab voltage sab raug puas thaum lub sijhawm ua haujlwm, nws tsis tuaj yeem rov qab tau ib ntus vim tias excitation 1PT khaws tag nrho cov hluav taws xob hauv kev kho lub txee ntawm lub tshuab hluav taws xob excitation regulator A thiab generator transformer pawg B. Yog li ntawd, peb theem A, B thiab C txaus siab 1PT tam sim no raug xaiv los rub mus rau txoj haujlwm kho.Nws yog ua los ntawm kev ntsuas 2PT thib ob cua tsav kab thiab txuas mus rau qhov excitation 1PT thib ob cua tsav kab (piv txwv li qhov voltage ntawm excitation regulator A thiab B ntawm # 3 generator).Ua ntej tuav kom raug, cov chaw tsim khoom siv hluav taws xob tau tsim cov kev ntsuas hauv qab no kom ntseeg tau tias muaj kev nyab xeeb ntawm cov khoom siv.Thov ua raws li lawv thaum ua haujlwm.

(1) Lub zero sequence voltage ntawm lub tshuab hluav taws xob yuav tsum tau saib xyuas thaum lub sijhawm ua haujlwm thiab yuav tsum tsis pub tshaj 5V (zero sequence voltage ntawm lub tshuab hluav taws xob yuav tsum tau khaws cia ntawm qhov kev mus ncig ntawm 10V thiab 1S).Yog tias tus nqi siab dhau lawm, tshaj tawm rau cov ceg kab tam sim ntawd thiab ceeb toom rau cov neeg ua haujlwm saib xyuas.

(2) Nws yog txwv tsis pub khiav lag luam 1PT lub tshuab hluav taws xob excitation thaum lub sijhawm ua haujlwm (tam sim no peb-theem A, B thiab C ntawm 1PT yog nyob rau hauv kev sib cais, thiab thawj sab kev nyab xeeb tau raug tshem tawm thiab tshem tawm).

(3) Txhim kho qhov kev tshuaj xyuas thiab kev saib xyuas ntawm lub tshuab hluav taws xob thiab hloov pauv hloov pauv thiab kev tswj xyuas excitation.Tsis txhob kov cov kab txuas txuas ntxiv thiab lub qhov hluav taws xob thib ob thaum kuaj xyuas.Hloov lub txee qhov rooj yuav tsum tiv thaiv kev vibration ntau dhau.

(4) Tsis txhob ua haujlwm ntawm lub txee saib xyuas thiab lub zog ntawm lub tshuab hluav taws xob kom deb li deb tau, thiab tshaj tawm cov kev sib txuas uas ploj lawm thaum tsim nyog.

(5) Tam sim no, qhov ntsuas tsis ua haujlwm ntawm lub tshuab hluav taws xob 2PT yuav ua rau lub zog ua haujlwm tsis ua haujlwm ntawm pawg A thiab B ntawm lub tshuab hluav taws xob # 3, uas yuav ua rau kev mus ncig ntawm kev ua haujlwm ntawm lub tshuab hluav taws xob magnetization poob txij nkawm.Nws yog ib qho tsim nyog los npaj rau kev cuam tshuam ntawm magnetization poob mus txawv tebchaws.

(6) Yog tias 2PT txhaum raug kuaj pom hauv kev ua haujlwm ntawm lub tshuab hluav taws xob, tab sis lub tsev tsis mus, thiab nrog rau qhov tam sim no thiab qhov hluav taws xob ntawm lub rotor ntawm lub tshuab hluav taws xob. lub tshuab hluav taws xob mam li nco dheev poob mus rau xoom lossis zero, qhov hluav taws xob ntawm lub stator ntawm lub tshuab hluav taws xob poob, lub stator tam sim no nce, thiab lub zog reactive nkag mus rau theem, lub tshuab hluav taws xob yuav raug suav tias yog qhov poob magnetization, thiab lub tshuab hluav taws xob yuav nres tam sim ntawd.

Generator inter-tig txij nkawm yog qhov tseem ceeb ntawm kev hloov pauv luv luv ntawm tib ceg thiab cov ceg sib txawv.

Guangxi Dingbo Power Equipment Manufacturing Co., Ltd. tsim nyob rau hauv 2006, yog ib lub chaw tsim tshuaj paus ntawm diesel generator nyob rau hauv Suav teb, uas integrates tsim, muab, commissioning thiab txij nkawm ntawm diesel generator teeb.Cov khoom npog Cummins, Perkins, Volvo, Yuchai, Shangchai, Deutz, Ricardo, MTU, Weichai thiab lwm yam nrog lub zog ntau 20kw-3000kw, thiab dhau los ua lawv lub Hoobkas OEM thiab lub chaw thev naus laus zis.Yog tias koj muaj lus nug txog cov tshuab hluav taws xob diesel, pls xav tiv tauj Dingbo Fais fab.
