Iindlela ezahlukeneyo zeengcingo zomvavanyi wokumelana nomhlaba

Iindlela zokulinganisa umvavanyi wokumelana nomhlaba zihlala zinezi ntlobo zilandelayo: indlela ye-wire-wire, indlela ye-wire-three, i-four-wire method, i-clamp eyodwa kunye ne-double clamp method, nganye ineempawu zayo.Kumlinganiselo wokwenyani, zama ukukhetha indlela echanekileyo yokwenza umlinganiselo Iziphumo zibalabala.

1. Indlela yemigca emibini

Imeko: Kufuneka kubekho umhlaba owaziwa ngokuba nesiseko esihle.NjengePEN njalo njalo.Isiphumo esilinganisiweyo sisixa sokumelana nomgangatho olinganisiweyo kunye nomhlaba owaziwayo.Ukuba umhlaba owaziwayo uncinci kunokumelana nomgangatho olinganisiweyo, umphumo wokulinganisa ungasetyenziswa njengesiphumo somhlaba olinganisiweyo.

Isebenza: kwizakhiwo kunye nemigangatho yesamente, njl njl. Ukutywina iindawo apho iingqumba zomhlaba zingenakuqhuba.

Ucingo: i-e+es ifumana umhlaba phantsi kovavanyo.H+s bafumana umhlaba owaziwayo.

2. Indlela yemigca emithathu

Umqathango: Kufuneka kubekho iintonga ezimbini zomhlaba: umhlaba oncedisayo kunye ne-electrode enye yokufumanisa, kwaye umgama phakathi kwe-electrode yomhlaba ngamnye awukho ngaphantsi kweemitha ezingama-20.

Umgaqo kukongeza okwangoku phakathi komhlaba oncedisayo kunye nomhlaba ophantsi kovavanyo.Ukulinganisa umlinganiselo wokuhla kwamandla ombane phakathi komhlaba ophantsi kovavanyo kunye nee-electrode zeprobe.Oku kubandakanya ukulinganisa ukuchasana kwentambo ngokwayo.

Isebenza kwi: isiseko somhlaba, indawo yokwakhiwa komhlaba kunye nentonga yombane webhola yombane, i-QPZ yokumisa.

I-Wiring: s ixhunyiwe kwi-electrode yokufumanisa.h idityaniswe kumhlaba oncedisayo.I-e kunye nee-es zixhunyiwe kwaye emva koko zixhunywe kumhlaba olinganisiweyo.

3. Indlela yocingo ezine

Ngokusisiseko yindlela efanayo yocingo oluthathu.Xa indlela yocingo lwesithathu isetyenzisiweyo endaweni yendlela yocingo-ntathu, impembelelo yokumelana nokulinganisa intambo kwiziphumo zokulinganisa ukuxhatshazwa komhlaba ophantsi kupheliswa.Xa ukulinganisa, i-e kunye nee-es kufuneka zixhunywe ngokuthe ngqo kumhlaba olinganisiweyo ngokulandelanayo, ochanekileyo kakhulu kuzo zonke iindlela zokulinganisa ukuchasana komhlaba.

4. Umlinganiselo webamba elinye

Ukulinganisa ukuchasana kokumisa indawo nganye kwindawo yokubeka amanqaku amaninzi, kwaye musa ukuqhawula uxhulumaniso lomhlaba ukukhusela ingozi.

Isebenza kwi: isiseko samanqaku amaninzi, ayinakuqhawulwa.Ukulinganisa ukuchasana kwindawo nganye yoqhagamshelwano.

Iingcingo: Sebenzisa iiclamp zangoku ukujonga.Ngoku kwindawo evavanywayo.

5. Indlela yokubamba kabini

Imiqathango: i-multi-point grounding, akukho mfumba encedisayo.Ukulinganisa umhlaba.

I-Wiring: Sebenzisa i-clamp yangoku echazwe ngumvelisi we-grounding resister tester ukuxhuma kwi-socket ehambelanayo.Gqana izibophelelo ezimbini kwi-conductor yokumisa, kwaye umgama phakathi kwee-clamps ezimbini kufuneka ube mkhulu kune-0.25 yeemitha.
