Kugwiritsa nthaka mizere

Pofuna kupewa anthu kuipa kwa katundu wa magetsi ntchito yapadera zoteteza chipangizo RCD, mafyuzi, MCB (breakers dera) ndi zina chitetezo. Dongosolo yotchuka kwambiri ya chitetezo anthu amaona kuti kukhala mizere lapansi. Izi makamaka chipangizo earthing amene cholinga chake ndi kulumikiza "nthaka" ya munthu zidutswa za zida zamagetsi. Kapena, mwa kulankhula kwina, olumikizidwa kwa wina ndi mnzake mu yopingasa ndi ofukula maelekitirodi (diverters), wakumvera pamwamba pansi pa akuya ena.

Pa kukana a dera la zimakhudza:

• kutayipa, dongosolo ndi chikhalidwe cha nthaka;
• katundu wa maelekitirodi ya;
• maelekitirodi kuya yatsoka;
• chiwerengero cha maelekitirodi.

nthaka zinchito lagawidwa mitundu iwiri:

• Protection - lakonzedwa kuteteza zipangizo pa magetsi yochepa dera, anthu ku mavuto a mafunde oopsa zimene zimachitika pa nthawi ya vuto la.
• Antchito - AMATHANDIZA anakhumba ntchito ya unsembe magetsi kudzera grounding a ziwalo moyo.

The ndondomeko ya kulenga mizere

Musachite mantha funso kupanga pansi kuzungulira, chifukwa kusonkhanitsa mu kuchita, sayambitsa mavuto aakulu. Paudindo divertors kwa grounding angakhale abwino zitsulo kumathandiza kupeza ngodya zabwino ndi m'lifupi mbali 45 kapena 60 mm, mapaipi a diameters zosiyanasiyana. Grounding chiwembu mu mawonekedwe a makona ndi zabwino chifukwa pamene kuphwanya zotheka mgwirizano diverter mu imodzi mwa mizere, mizere kufanana kukhalabe ntchito.

Best yosayenera ogwiritsa dera peaty mtundu nthaka loamy dothi ndi dongo ndi digiri yapamwamba ya chinyezi. Mtundu koipa dothi - pamiyala.

Ndi bwino kusankha malo enieni kusonkhanitsa pansi kuzungulira, ndi malo akadakwanitsira mukhoza kutengedwa ngati ozungulira switchgear lapansi. Grounding ikhale wa kasakaniza wazitsulo mkuwa kapena wakuda kapena kanasonkhezereka zitsulo popanda kupenta.

Fosholo anakumba ngalande mu mawonekedwe a makona ndi mbali ya mamita 3, kuya ndi zazing'ono - mamita 0.5-0.8. The makona mfundo kukhomerera zitsulo earthing kutalika 2.5-3 m. Malekezero akhoza wakuthwa metal kosavuta kuika mu nthaka. Pamwamba nthaka malo pang'ono, mpaka 20 cm, ndi welded ku zitsulo yopingasa amavula iwo, zikubweretsa zopangira chishango magetsi. china chotulutsa sadzakhala superfluous kusamalira odana ndi dzimbiri utoto kapena Mwachitsanzo, phula.

Pambuyo ogwiritsa ntchito nthaka muyeso dera, mmene muyeso ulamuliro ikuchitika mlingo wake kukana. Izi zachitika ndi chipangizo, ndilo lotchedwa megohmmeter. Ananenanso miyezo anapanga osachepera 1 nthawi pachaka. Chifukwa chaichi kudzera chipangizo grounding ayenera kutseka dera ndi kupanga magetsi, ndiye kuti ulamuliro miyeso mu dontho dera voteji. Pafupi elekitirodi waukulu oyenerera wothandiza ndi kugwirizana kwa gwero. Meter atathana angathe pafupi ziro ukulu dontho la voteji pa elekitirodi chachikulu. njira uyu ali grounding dera chimaonekera zambiri kuposa njira zina.
