Nzira yekushandisa sei voltage tester zvakachengeteka?

Kunyangwe iko zvino yave yakavimbika inomira voltage tester, mukuita basa, inogona kukonzera njodzi kune vanoshanda nekuda kwemamwe matambudziko senge pesvedzero yevashandisi pachavo kana kunze kwenyika.Naizvozvo, ese ari maviri mabhizinesi ane hunyanzvi mukugadzira anomira nemagetsi testers uye mabhizinesi akakodzera anoshandisa mavoltage testers anofanirwa kuedza nepaanogona napo kudzivirira kuitika kwenjodzi dzakadai, Saka nzira yekudzikisa rudzi urwu rwengozi inogona kuitika?

Kazhinji kutaura, akawanda epamusoro-ekupedzisira anomira voltage testers akagadzirwa neakamisikidzwa akangwara anti-high-voltage electric shock system.Iyi sisitimu inonziwo smart GFI kwenguva pfupi.Inogona kuona maererano nekushandiswa kwemhando dzemazuva ano.Kana dambudziko rekuvhundutsa kwemagetsi uye kudonha rikaitika, iyo inokwanisa kumira voltage tester inongo cheka iyo yakakwira-voltage kubuda mune imwe millisecond, Kuve nechokwadi chekuchengetedzwa kwevashandisi.Naizvozvo, pasi pemamiriro akafanana ekushanda, munhu anokwanisa kumira voltage tester, chero bedzi mushandisi asingaite zvikanganiso zvakawandisa, haawanzo kurwisa opareta yemagetsi kuvhunduka uye dzimwe njodzi.

Kuti uchengetedze vatengi nevashandisi, vagadziri ve pressure tester vanofanirwa kupedzisa akati wandei marudzi ebvunzo dzekuchengetedza kana vapedza kugadzirwa kwemidziyo, kuitira kuti ive nechokwadi chekuti zvigadzirwa zvinoenderana nezvinodiwa nemaindasitiri echimiro chechigadzirwa, basa uye maitiro ekugadzirisa. .Inosanganisira voltage standstand test, insulation test, etc. bvunzo dzekudzivirira dzinofanirwa kuitwa zvikamu zvisati zvaiswa nemugadziri, kunyanya kudzivirira izvo zvisina kukodzera kuti zvigadzirwe muchigadzirwa uye zvichikonzera njodzi dzinogona kuitika.Parizvino, mugadziri ane hunyanzvi, kugadzirwa kwayo, kuyedzwa uye mamwe maitiro anofanirwa kuitwa achinyatsoenderana neISO yenyika zviyero, uye zvigadzirwa zvekupedzisira zvinofanirwa kusvika kune ISO world certification zviyero, kureva, kubva kune zvikamu kusvika kune zvakapedzwa zvigadzirwa. inofanira kusvika kune ISO world certification quality standards, nenzira iyi chete ndipo patinogona kubvisa zvirinani njodzi dzinogona kuitika.Hongu, kushandiswa kwemakambani emidziyo ane hukama, asiwo nguva dzose kuronga kushanda kwevashandi vekudzidzira, itsva inofanira kunge iri pasi pekutarisirwa kwevashandi vekare vane ruzivo kuti vashande, kuitira kudzivirira zvachose njodzi inokonzerwa nezvikanganiso zvekushanda.

1. Ndezvipi zvakanakira AC kutsungirira voltage test

Kazhinji, AC inomira voltage tester iri nyore kuwana rutsigiro rwekuchengetedza sangano pane DC inomira voltage tester.Chikonzero chikuru ndechekuti zvizhinji zvezvinhu zvakaedzwa zvichashanda pasi pe AC voltage, uye AC inomira voltage test inopa mukana wekuchinjanisa mapolarities maviri ekuisa kumanikidza kune insulation, iri padhuze nekumanikidza kunosangana nezvigadzirwa mukushandiswa chaiko.Nekuti iyo AC bvunzo haizobhadharise iyo capacitive mutoro, kuverenga kwazvino kunoenderana kubva pakutanga kwevoltage application kusvika kumagumo ebvunzo.Saka, sezvo pasina dambudziko rekudzikamisa rinodiwa kutarisa kuverenga ikozvino, hapana chikonzero chekuwedzera voltage nhanho nhanho.Izvi zvinoreva kuti kunze kwekunge chigadzirwa chiri pasi pekuyedzwa chanzwa mhepo yakangoerekana yaiswa, mushandisi anogona kubva angoisa iyo yakazara voltage uye overenga yazvino pasina kumirira.Nekuti iyo AC voltage haizobhadharise mutoro, hapana chikonzero chekuburitsa michina yakaedzwa mushure mebvunzo.

2. Ndezvipi zvakakanganiswa zve AC voltage tester?

Kana capacitive mutoro ukaedzwa, iyo yakazara ikozvino ine reactance ikozvino uye leakage ikozvino.Kana iyo yekupokana ikozvino yakakura kupfuura iyo yekuvuza ikozvino, zvingave zvakaoma kuona zvigadzirwa zvine yakawandisa leakage ikozvino.Paunenge uchiyedza hombe capacitive mutoro, iyo yakazara ikozvino inodiwa yakakura kupfuura iyo yekuvuza ikozvino pachayo.Nekuti mushandisi akatarisana neakawanda ikozvino, iyi inogona kunge iri njodzi huru.

3. Ndezvipi zvakanakira DC kutsungirira voltage bvunzo?

Kana iyo DUT yachajiswa zvizere, iyo chaiyo leakage ikozvino inoyerera.Izvi zvinogonesa iyo DC kumirisana nevoltage test chiridzwa kuratidza zvakajeka iyo chaiyo leakge ikozvino yechigadzirwa chiri mukuedzwa.Nekuda kwekuti kuchaja iko kupfupi, simba rinodiwa neDC rimire voltage tester rinowanzo diki pane iro reAC inomira voltage tester inoshandiswa kuyedza chigadzirwa chimwe chete.

4. Ndeapi akaremara eDC anomira voltage tester?

Nekuti DC voltage inomira bvunzo inochaja chinhu chiri mukuyedzwa (DLT), kuitira kuti ibvise njodzi yekuvhunduka kwemagetsi kweanobata chinhu chiri muyedzo (DLT) mushure meiyo voltage inomira bvunzo, chinhu chiri mukuyedzwa (DLT) chinofanira kuve akaburitswa mushure mebvunzo.Iyo DC bvunzo ichachaja iyo capacitor.Kana iyo DUT ichinyatso shandisa AC simba, iyo DC nzira haitevedzere mamiriro chaiwo.
