Nei tichifanira kuwedzera mudziviriri?

Mumwe dzekuziva kuti chakaipa nokushanda zvemagetsi chinhu akatsiga simba zvitengeswa. voltage Kuchinja mains vanogona achitsoropodza kukanganisa kushanda mudzimba kana zvimwe mudziyo. Semiconductor zvinoriumba zvinopa zvimwe mikana kukura siyana mano. Zvinosuwisa vari nehanya anodawo mamiriro uye zvinodiwa kungwarira kurapwa. Chimwe namano ayo anogona kudzivirira zvemagetsi kubva kukuvara nokuda simba RINOFAMBIRA kana mukuru kwevari zvechivhurumukira ruzha iri wedzerai network, ndiyo nomumbure firita. Kwaanoita rayo basa uye kunowedzera upenyu huchashandiswa.

Ngativerengei kuona simba nerubatsiro uye tarisai kuti mhando dzakasiyana yevatengi sei muzviruva ayo. Uye sezvo nomumbure Sefa anoponesa wemagetsi muchiwirirana? Zvakanakisa, pomugove voltage chinhu sinusoid. Zviri nguva dzose mamiriro ayo (amplitude) uye maitikiro. Zvinosuruvarisa, kana vatengi simba magetsi chine siyana kukanganiswa, izvo zvinogona kukuvadza michina.

Muupenyu hwezuva nezuva zvakadai "ruzha" midziyo yemagetsi zvinosanganisira vacuüm cleaners, sefiriji kana mhepo conditioners. Ndiko basa kana mamwe marudzi asynchronous Motors, iva nechokwadi chokuti nokumonyaniswa mu romugove Network. Izvi imhaka sparking ari Kukwesha kana kuti dzimwe chikonzero. Kunyange munhuwo mashandiro electric shaver zvinogona kuvhiringa Somuenzaniso, nhepfenyuro vagamuchiri. Nemamwe mashoko, akapa vane inductive mutoro uye kuti pfupi zororo ane zvemagetsi vematunhu (sezvakaita iri injini brushes) chipingaidzo kuwa muna mains wedzerai. Vane pfupi overvoltage pulses. Kuwedzera mudziviriri, chaizvoizvo, akamisa kubata anomalies akadaro.

Asi dambudziko harisi chete dzemagetsi Motors. Kunyange chete kwemarudzi zvikuru "ruzha" mano vari pachavo zvemagetsi ano: materevhizheni, stereos, makombiyuta, etc. Zvakaratidza kuti sefungu mudziviriri anokwanisa kudzivirira zvemagetsi muchiwirirana, ndiro pachachowo pave vanoshorwa ezvinhu basa ravo. Chokwadi kuti ano mano akaumbwa nokuchinja simba rinopiwa, ane basa riri chokuita kakawanda 1000 Hz kana kupfuura. Sezvo pasuo vakadaro mano vari transformers kuva imwe inductance, chipingaidzo ipapo chinoitika.

Ndivo nyore kuona nomunhu oscilloscope. Unogona unganidza chiduku pakaitika mudziviriri nemaoko ako kuitira kubudirira chikumbiro chacho. Zviri zvokuti pave inductance, izvo zvichaita kuti ndima mukuru-kakawanda ruzha iri mains wedzerai. Nokuti chinangwa ichi nyore putira imwe nhamba majana ose waya Somuenzaniso, mavanga pamusoro kusona ferrite mhete uye solder nayo successively kuti zvokudya redunhu kombiyuta. With nokuwedzera inductance (nhamba muchichinjana) unogona kuona pamusoro oscilloscope kuti kukanganiswa kuchanyangarika zvishoma nezvishoma.

Pari zvino pane vazhinji samambure filters kuti akanyorerwa kushanda-siyana mutoro. A wakanaka iyi angava mutsetse Sefa Pilot, ine rakaisvonaka unongotaura.
