Isixhobo soMbane esine-Voltage ephezulu kufuneka sigcine i-Insulation egqwesileyo ngexesha lokuSebenza, ngoko ke uthotho lweeMvavanyo ze-Insulation kufuneka ziqhutywe ukususela ekuqaleni kokuveliswa kwezixhobo.Olu vavanyo lubandakanya: Uvavanyo lweMveliso yeMveliso, uVavanyo oluPhakathi kwiNkqubo yeMveliso, iiMveliso zoMgangatho weMveliso kunye noVavanyo lweFactory, Sebenzisa iimvavanyo zoFakelo lweSiza, kunye noVavanyo lwe-Insulation Preventive yokuKhusela kunye nokusebenza ngexesha lokusetyenziswa.Ubungqina beZixhobo zoMbane kunye namaLingelo oThintelo zezona ziMfuniselo ziBalulekileyo ziBini.IRiphabhlikhi yaBantu baseTshayina iKhowudi yoMveliso woMbane woMbane kunye neKhowudi yeSizwe: DL/T 596-1996 “Iinkqubo zoVavanyo eziThintelayo kwiZixhobo zoMbane” kunye ne-GB 50150-91 “IiNkcazelo zoVavanyo lokuTshintshwa kweSixhobo soMbane” Cacisa imixholo kunye neeNgcaciso zoMfuniselo ngamnye.
2. I-Insulation Preventive Experiment
Uvavanyo loThintelo lwe-Insulation yeZixhobo zoMbane ngumlinganiselo obalulekileyo wokuqinisekisa ukuSebenza okuKhuselekileyo kweZixhobo.Emva koVavanyo, iSimo se-Insulation yeSixhobo sinokubanjwa, Ingozi kwi-Insulation inokufumaneka ngexesha, kwaye ukuKhuselwa kunokususwa.Ukuba kukho iNgxaki eMandundu, kuyafuneka ukuba kufakwe enye indawo yesiXhobo ukunqanda iilahleko ezingenakulungiseka, ezinje ngokuphela kombane okanye ukonakaliswa kwezixhobo ezibangelwa kukungaphumeleli kwe-insulation ngexesha lokusebenza.
Amalingo oThintelo lwe-Insulation anokwahlulwa abe ngaMacandelo amabini: elinye liLingelo elingangonakalisiyo okanye uVavanyo lweNkalo ye-Insulation, ebhekiselele kwiiParameters zeempawu ezahlukeneyo ezilinganiswe kumbane ophantsi okanye ngezinye iindlela ezingayi konakalisa i-Insulation, kubandakanywa nokulinganisa i-Insulation Resigency, I-Dielectric Loss Tangent, njl. Emva koko uQinise ukuba i-Insulation inezo naziphi na iintsilelo.Iimvavanyo zibonise ukuba le ndlela iluncedo, kodwa ayinakusetyenziselwa ukumisela ngokuthembekileyo amandla ombane we-Insulation.Olunye luvavanyo olutshabalalisayo okanye uvavanyo loxinzelelo.I-Voltage eFakelwe kuVavanyo iPhakamileyo kuneVoltage yokuSebenza yeSixhobo, kwaye iiMfuneko zoVavanyo lwe-Insulation zingqongqo kakhulu.Ngokukodwa, kukho umngcipheko omkhulu wokuvezwa kunye nokuqokelelwa kweentsilelo, kunye nokuqinisekisa ukuba i-Insulation inamandla athile oMbane, kubandakanya i-DC ukumelana nombane, unxibelelwano olunokumelana nombane, njl njl. Umonakalo kwi-Insulation.
3. UVavanyo lokuHanjiswa kweZixhobo zoMbane
Ukuze kuhlangatyezwane nezidingo zobuNjineli boFakelo loMbane kunye noVavanyo lokuTshintshwa kweZixhobo zoMbane, kwaye uPhakamise ukuPhakanyiswa kunye nokuSetyenziswa kweTekhnoloji eNtsha yoMfuniselo woFakelo lwesiXhobo soMbane, uMgangatho weSizwe we-GB 50150-91 "IsiXhobo soMbane sokuTshintsha uMfuniselo kunye neNkcazelo yoMfuniselo ngokuthe ngqo" IiNkcazo zeMvavanyo ezahlukeneyo.Ukongeza kwezinye iiMfuniselo zoThintelo lwe-Insulation, iiMfuniselo zokuTshintsha iziXhobo zoMbane nazo zibandakanya ezinye iimvavanyo zeempawu, ezifana neTransformer DC Resistance kunye neRatio Experiments, iCircuit Breaker Loop Resistance Experiments, njl.
4. UMGaqo oSisiseko we-Insulation Preventive Experiment
4.1 UVavanyo lwe-Insulation Resistance Test Lolona lusetyenziswa kakhulu kwaye luLungela kakhulu kuVavanyo lwe-Insulation yeSixhobo soMbane.Ixabiso lokuxhathisa i-Insulation inokubonakalisa ngokufanelekileyo iintsilelo ze-Insulation, ezifana nokufuma okupheleleyo, ukusuleleka, ukutshisa ngokugqithisileyo kunye nokuguga.Esona sixhobo sisetyenziswa ngokuqhelekileyo ukuVavanya i-Insulation Resistance yi-Insulation Resistance Tester (i-Insulation Resistance Tester).
Abavavanyi be-Insulation Resistance Testers (Isolation Resistance Testers) Ngokuqhelekileyo baneentlobo ezifana ne-100 Volts, 250 Volts, 500 Volts, 1000 Volts, 2500 Volts, kunye ne-5000 Volts.I-Insulation Resistance Tester kufuneka isetyenziswe ngokuhambelana ne-DL / T596 "Iinkqubo zoVavanyo zokuThintela kwiZixhobo zaMandla".
4.2 Uvavanyo lwangoku lokuvuza
IVoltage ye-General DC Insulation Resistance Tester iPhantsi kune-2.5KV, engaphantsi kakhulu kunoMbane oSebenzayo weSixhobo soMbane.Ukuba ucinga ukuba iVoltage yokulinganisa ye-Insulation Resistance Tester iphantsi kakhulu, unokulinganisa ukuvuza kwangoku kwezixhobo zombane ngokongeza i-DC High Voltage.Izixhobo ezisetyenziswa ngokuqhelekileyo zokulinganisa ukuvuza kwangoku kubandakanya iiTransformers zoMfuniselo eziPhezulu-Voltge kunye ne-DC High-Voltage Generators.Xa isixhobo sineentsilelo, ukuvuza okukhoyo ngaphantsi kombane ophakamileyo kukhulu kakhulu kunoko kuphantsi kombane ophantsi, oko kukuthi, ukuchasana kwe-Insulation phantsi kombane ophakamileyo kuncinci kakhulu kunaphantsi kombane ophantsi.
Akukho mahluko mninzi phakathi kokuvuza kwangoku kunye nokuxhathisa kwi-Insulation ye-Medical Testing Tester yokuMeta isiXhobo soMlinganiso, kodwa uMlinganiselo wangoku wokuvuza unezi mpawu zilandelayo:
(1) I-Voltage yoVavanyo iphezulu kakhulu kuneyoMhloli we-Insulation Resistance Tester.Iintsilelo ze-Insulation ngokwayo zivezwa ngokulula, kwaye ezinye iintsilelo zokuGuqulela ngaphandle kokungena ziyafumaneka.
(2) Ukulinganisa uQhagamshelwano phakathi kokuvuza kwangoku kunye neVoltage eSetyenzisiweyo inceda ukuhlalutya iintlobo zeZiphene ze-Insulation.
(3) I-Microampere eSetyenziselwe ukuvuza koMlinganiso wangoku ichanekile ngakumbi kune-Insulation Resistance Tester.
4.3 I-DC imelana noVavanyo lweVoltage
Uvavanyo lwe-DC Ukumelana noVavanyo lweVoltage lunePhezulu
Unxibelelwano lokujamelana nokuLingwa kweVolthage Ngamanye amaxesha Kwenza ukuba obunye ubuthathaka kwi-Insulation bubonakale ngakumbi.Ke ngoko, kuyafuneka ukwenza iiMfuniselo zokuChasa i-Insulation, inqanaba lokufunxa, ukuvuza kwangoku kunye nelahleko ye-Dielectric ngaphambi kovavanyo.Ukuba isiphumo sovavanyo siyanelisa, unxibelelwano olunokumelana novavanyo lweVoltage lunokuqhutywa.Ngaphandle koko, kuya kufuneka kujongwana nayo kwangexesha, kwaye unxibelelwano olujongene novavanyo lweVoltage kufuneka lwenziwe emva kokuba ujoliso ngalunye lufanelekile ukunqanda ukonakala okungafunekiyo kwe-Insulation.
4.5 Uvavanyo lweFactor yeLahleko yeDielectric Tgδ
I-Dielectric Loss Factor Tgδ yenye yeeNjongo eziBalulekileyo eziBonisa ukusebenza kweInsulation.I-Dielectric Loss Factor Tgδ Ibonakalisa iParameter ye-Character ye-Insulation Loss.InokuFumana ngokuKhokelekayo ukugqunywa kwezixhobo zoMbane kukonke okuchatshazelwa kukumanzisa, ukuwohloka, kunye nokuwohloka, kunye neziphene zeNdawo zeZixhobo ezinoBuncinci.
Ukuthelekisa i-Medical Withstand Voltage Tester to Insulation Resistance and Leakage Current Tests, I-Dielectric Loss Factor Tgδ Inezinto eziluncedo ezibalulekileyo.Ayinanto yakwenza noVavanyo lweVoltage, ubungakanani beSampuli yoVavanyo kunye nezinye izinto, kwaye kulula ukwahlula uTshintsho lwe-Insulation yeZixhobo zoMbane.Ke ngoko, i-Dielectric Loss Factor Tgδ yenye yolona vavanyo lubalulekileyo kuVavanyo lwe-Insulation ye-High-Voltage Electrical Equipment.
I-Dielectric Loss Factor Tgδ Inokuba luncedo ekufumaneni ezi ntsilelo zilandelayo zoKhuseleko:
(1) Ukufuma;(2) Ukugqobhoza kwi-Conductive Channel;(3) I-Insulation iqulethe iiBulu zoMoya zaMahla, kwaye i-Insulation i-Delaminates kunye ne-Shells;(4) I-Insulation ingcolile, iyancipha, kwaye iyaguga.
