MASHANDURO EPASI

An earthing transformer, inonziwo grounding transformer, imhando ye transformer iyo inoshandiswa kugadzira inodzivirira pasi yekubatanidza kune magetsi emagetsi. Iyo ine mhepo inotenderera yemagetsi yakabatana nenyika uye yakagadzirirwa kugadzira nzvimbo isina kwayakarerekera iyo yakadzikwa.

Earthing transformers inoita basa rakakosha mukuchengetedza magetsi. Izvo zvinoshandiswa kuderedza njodzi yemagetsi emagetsi uye kudzivirira midziyo kubva pakukuvadzwa kunokonzerwa nekukanganisa kwemagetsi. Mumagetsi emagetsi apo pasina hukama hwechisikigo kupasi, senge mu-high-voltage transmission network, shanduko yepasi inoiswa kuti ipe yakachengeteka uye yakavimbika grounding connection.

Earthing transformers anowanzo shandiswa mumagetsi emagetsi, reactor zvikamu, uye masisitimu emagetsi. Izvo zvakagadzirirwa kuve nereshiyo yakaderera pane yakajairwa magetsi ekushandura, izvo zvinoreva kuti ivo vanogona kutakura yakakwira ikozvino pasina kugadzira yakakwira voltage. Chiyero cheiyo earthing transformer inowanzoiswa ku1: 1, zvinoreva kuti magetsi ekuisa uye kubuda kwemagetsi zvakafanana.

Magadzirirwo emagetsi epasi anosiyana zvichienderana nekushandiswa uye rudzi rwemagetsi aari kushandiswa mukati. Mamwe magadzirirwo evhu akagadzirwa kuti anyudzwe neoiri, asi mamwe ari akaoma-mhando transformer. Kusarudzwa kwemhando ye transformer uye dhizaini zvinoenderana nezvinodiwa chaizvo zvemagetsi system.

Earthing transformers anoshandiswawo mumasisitimu emagetsi kudzikisa kushanduka kwemagetsi uye kugovera chiyero. Inogona kushandiswa mumasisitimu emagetsi uko kune mitoro isina kuenzana kana uko kune misiyano yakakura mukudiwa kwemutoro.

Mukupedzisa, vashanduri vepasi zvinhu zvakakosha mumasisitimu emagetsi, vachipa hukama hwakachengeteka uye hwakavimbika hwepasi uye kuchengetedza midziyo yemagetsi kubva mukukuvadzwa kunokonzerwa nekukanganisa kwemagetsi. Dhizaini uye kuisirwa kwevhu kushandura kunoenderana nezvinodiwa zveiyo chaiyo magetsi sisitimu, uye ivo vanoita basa rakakosha mukuchengetedza magetsi uye kugadzikana kwehurongwa.

Earthing transformers zvinhu zvakakosha mumagetsi emagetsi masisitimu, akanyanya kugadzirwa kuti ave nechokwadi chekuchengetedza uye kushanda kwakavimbika kwehurongwa. Aya ma transformer anoshanda chinangwa chakakosha nekubatanidza nzvimbo isina kwayakarerekera yematatu-chikamu simba rekugovera network kune pasi. Heano zvimwe zvakakosha zveevhu transformers:

• Neutral Grounding: Mune matatu-chikamu simba system, imwe yemakondakita inosarudzwa seyasina kwayakarerekera, iyo inowanzobatanidzwa nepasi nekuda kwezvikonzero zvekuchengetedza. The earthing transformer inoshandiswa kumisa kubatana uku. Inova nechokwadi chekuti nzvimbo isina kwayakarerekera iri pane kana pedyo nekugona kwepasi.

• Kuiswa kwemurwere kwake ega: Earthing transformers akagadzirwa ane yakasarudzika yechipiri mhepo. Izvi zvinoreva kuti mafungu ekutanga uye echipiri haana kubatana zvakananga, achipa kuparadzaniswa kwemagetsi pakati pehurongwa uye pasi. Kuzviparadzanisa nevamwe kwakakosha pakuchengetedza uye kuona kukanganisa.

• Resonance Suppression: Mune mamwe masisitimu emagetsi, resonance mamiriro anogona kuitika nekuda kwe capacitance yemitsara yakareba pamusoro. Earthing transformers inogona kubatsira kudzikisira nyaya iyi nekupa yakaderera-resistance nzira kusvika pasi, kudzivirira overvoltages uye kukuvara kunogona kuitika kune system.

• Fault Current Limiting: Earthing transformers inogona kuve yakashongedzerwa negrounding resistors kudzikamisa kutadza kwemhepo panguva yekukanganisa kwepasi. Izvi hazvingo chengetedza sisitimu kubva kune yakawandisa ikozvino asi zvakare inobatsira mukutsvaga nekuzviparadzanisa nekukanganisa nekukurumidza.

• Mhando dzeEarthing Transformers: Kune marudzi akasiyana-siyana eivhu shandurudzo, anosanganisira akasimba pasi, impedance yakadzika, uye inodzivirira inodzika midzi. Sarudzo yerudzi inoenderana nezvinodiwa chaizvo zvesimba system uye dhigirii rekudzivirira kukanganisa kunodiwa.

• Kuchengeteka uye Kuvimbika: Kugadzika kwakakodzera kuburikidza nevhu rekushandura kunosimudzira chengetedzo yekuisirwa magetsi nekudzikisa njodzi yekuvhunduka kwemagetsi nemoto. Inobatsirawo kuve nechokwadi chekushanda kwakavimbika kwemagetsi ekugovera masisitimu nekudzivirira kukanganiswa kwechikamu-kune-pasi uye kusaenzana kwemagetsi.

• Maintenance: Kugara kugadziridzwa uye kuyedzwa kwepasi transformer kwakakosha kuti ive nechokwadi chekuenderera kwavo kushanda mukupa yakachengeteka uye yakavimbika nharaunda yemagetsi.
