Ndechipi pfupi-redunhu iyezvino?

Chemical manyuko nemagetsi (mabhatiri uye accumulators) saka kwazvo muupenyu hwedu, achiva chinhu yaizivikanwa uye sezvingatarisirwa, kuti varidzi vakawanda havatombobvumi kuverenga zvakanyorwa pamusoro Mabhokisi dzavo uye package. Uye pasina, nekuti pane inyevero inonakidza chaizvo - "Regai kuvhara". Ndiani kunyange zvishoma kujairana kunyatsogona magetsi, anonyatsoziva kuti yakadaro pfupi-redunhu ano, uye nei kuita ushamwari.

Chero simba zvitengeswa nguva dzose ane mapango maviri: akanaka uye kunaka (+ uye -) kuti kutungamirira kutira, uyewo Pasika uye pasi (razero gobvu, dzimwe nguva mumwe chokutambudzika) nokuti shanduka. mhosva nezvimedu sangano zvinogoneka chete chiitiko kuti matanda aya zvakabatana pedyo conductive zvinhu. Kana pakaputsika muitisi kubatanidza mudziyo, kuitika kupfuura kubudikidza chikwata matunhu, zvimwe basa akaita. The chikuru chepfungwa - the yakanatsa Appliance cheni haabvumiri maerekitironi kupfuura akasununguka, saka nguva dzose tinogona kufunga kuti pane kurwisa (mutoro) iro ichikutadzisa kufadza okuyerera nezvimedu (pfupi remudunhu richidzidzwa).

Nokuti vakasununguka njere tinopa muenzaniso kuti mvura inoyerera kuburikidza kupa (kondakita). yerera kutanga - iyi ndiyo imwe padanda, uye kuguma - danda wechipiri. The pakati gwara dzinongoda mashizha mvura chigayo (mutoro), rotatable kufamba mvura (kuitika). Zviri pachena, kuerera mwero anogara shoma nokuda kurwisa pamusoro mashizha. Asi chii chinoitika kana chigayo rapera? Water haadi kuona nemishonga, tichimhanya kupa vane sipidhi inodiwa, iyo ichapa kuchiunza (dunhu pfupi). Kunenge chaizvo kukuvara ichivhiringidza chokubuda saiye uye chiteshi. Magetsi kuyerera mwero - ndiro simba kuitika mudunhu pfupi.

Ndizvowo zvinoitika mune magetsi. Kana paine chikonzero chinoita kuti kurwisa kwemutariri anotanga kuenda zero, zvadaro pfupi-redunhu ano. Pakazoti muitisi riri pakutsamwisana uye kuitika bhuku wakaremara. Ichi uchishandisa kwadzinoita simba chirimwa ane yenjodzi uye kunoda pakarepo kubviswa. Kazhinji, dunhu mudariki iri akagadzawo kubvambura redunhu kana vari wakaiswa pfupi-redunhu ano. By Fananidzo nemvura kuerera ndima kukurukurirana kwacho uye haarambi. Kana iwe chokukuvadza kunobva simba kuona chokwadi ane redunhu pfupi iri zvemasanga chikamu redunhu inogona nyore. Nokuti chinangwa ichi, pakaitwa mudziyo (multimeter) uyere kurwisa ukoshi pakati zvakatinakidza chikumbiro vachiongorora. The kunanga nzira iri inobva chamazuva chinoratidza kana zvinozivikanwa kuti zvakananga kuonana pamusoro mugove tarisa chedanda haafaniri kuva, ipapo ishande nenzira ichi. In simba midziyo riri basa kudarika chairo metering multimeter nemishonga.

Nenzira, ndicho chikonzero haugoni akakiya bhatiri matanda. Kunyange zvazvo simba ravo hazvina kukwana yekudyidzana kukuvadza kondakita, asi mukati makemikari zvinoumba pfupi-redunhu nokukurumidza zvinoshatisa, achidzikisa zvinonyatsorehwa simba zvekuvaka basa.

Kudzidza zvemagetsi kuchengeteka inowanzoshandiswa rokuti "tinzwe pfupi-redunhu ano." It inorondedzera kupfuura ano, hwava somugumisiro dunhu pfupi. The Dunhu AC kunonyanyisa kukosha kwayo kuchaita kusvikwa papera hafu nguva (kubvira 0.01 kusvika 50 Hz).

Zvinofanira kucherechedzwa kuti pane magetsi chaiyo mudziyo, izvo pfupi-redunhu muoti haisi chimbichimbi, sezvo zvakajairika. Muenzaniso unoshamisa - Welding midziyo umo arc the chete kuonekwa uye rinoonekwa pfupi-redunhu ano.
