Umahluko kwiindlela zoVavanyo phakathi koMvavanyi we-Insulation Resistance Tester kunye neGround Resistance Tester
(1) Indlela yoVavanyo lwe-Insulation Resistance Tester
I-Insulation Resistance Tester kuVavanya iDegree ye-Insulation phakathi kwezigaba, iiLayers kunye neeNdawo ezingathathi hlangothi zeengcingo kunye neentambo.Elona liPhakamileyo iValue yoVavanyo, Ingcono iNtsebenzo yokuKhusela.I-Insulation Resistance inokulinganiswa ngu-UMG2672 Electronic Megohmmeter.
(2) UVavanyo lweNdlela yoVavanyo lweMvavanyi yokuNzalisa ukuGrounding
I-Grounding Resistance Tester siSixhobo saMandla esichonga ukuba i-Grounding Resistance ifanelekile.Indlela yoVavanyo ye-Grounding Resistance tester kukuba isiXhobo soMbane siQhagamshelwe Kwasesenokwenzeka nguMhlaba, kwaye kukuValeka kocingo lokusabela okanye iConductor yoMbane ePhantsi eMhlabeni.Ixabiso elilinganiswe nguMvavanyi wokuNchasa iGrounding ngumlinganiselo osebenzayo wokuqinisekisa uKhuseleko lobuqu.Unokukhetha i-DER2571 ye-Digital Grounding Resistance Tester eveliswe yi-WeiA Power.
Okwesine, Umahluko woMgaqo phakathi koMvavanyi wokuChasa i-Insulation kunye ne-Ground Resistance Tester
(1) Umgaqo we-Insulation Resistance Tester
Xa i-Insulation Resistance Tester isetyenziselwa ukulinganisa ukuchasana kwe-Insulation, i-DC Voltage U isetyenziswe kwi-Insulation.Ngeli xesha, iNguqulelo yangoku iTyantyono kunye nexesha, kwaye ekugqibeleni ithandeka kwixabiso elizinzileyo.
Ngokubanzi, Indawo yangoku yoMvavanyi weInsulation Resistance yiSimbuku seCapacitance yangoku, i-Absorption yangoku kunye neConduction yangoku.I-Capacitive yangoku IC, i-Speed Attenuation Speed Ikhawuleza kakhulu;I-Absorption yangoku i-Iaδc, Ibola kancinane kuneCapacitive yangoku;I-Conduction Inp yangoku, idla ngokuzinza ngexesha elifutshane.
Ngexesha loVavanyo usebenzisa i-Insulation Resistance Tester, ukuba i-Insulation ayimanzi kwaye umphezulu ucocekile, amacandelo akhoyo ngoku i-ic kunye ne-Iaδc iya kubola ngokukhawuleza ukuya ku-Zero, ishiya kuphela iNcinci encinci yokuPhuma, kuba ukuchasana kwe-Insulation kuphambene. I-Proportional to the Current Current , I-Insulation Resistance iya kunyuka ngokukhawuleza kwaye izinze kwixabiso elikhulu.Ngakolunye uhlangothi, ukuba i-Insulation imanzi, i-Conduction yangoku inyuka kakhulu, ikhawuleza kunexabiso lokuqala lokufunxa i-Iaδc yangoku, icandelo elidlulayo lincitshiswe kakhulu, kwaye ixabiso lokuchasa i-Insulation liphantsi kakhulu, kwaye litshintsha kakhulu ngexesha.Micro.
Ke ngoko, kuVavanyo lwe-Insulation Resistance Tester, uMxholo wokufuma we-Insulation ngokuqhelekileyo ugwetywe ngeRatio yokufunxa.Xa i-Absorption Ratio iKhulu kune-1.3, ibonisa ukuba i-Insulation igqwesile.Ukuba i-Absorption Ratio isondele kwi-1, ibonisa ukuba i-Insulation imanzi.
(2) Umgaqo-siseko we-Grounding Resistance Tester
I-Grounding Resistance Tester ikwabizwa ngokuba sisiXhobo sokuMeta ukuNika iGrounding, iShaker eGrounding.Umgaqo-siseko woVavanyo woVavanyo lweGround Resistance kuFumana iXabiso loKuchasa uMgangatho "Rx" Nge-AC Constant Yangoku "I" phakathi kweGround Electrode "E" kunye ne-Power Supply Electrode "H (C)" yeNto ephantsi kovavanyo, Kwaye i-Grounding ifunyenwe Umahluko weNdawo "V" phakathi kwe-Electrode "E" kunye ne-Electrode yokulinganisa "S(P)".
