Insulation Resterance Tester (zvakare inonzi akangwara Dual kuratidza insulation kupokana tester) ine mhando nhatu dzemiedzo dzinoshandiswa kuyera kupesana nekupokana. Muedzo wega wega unoshandisa nzira yayo pachako, kutarisa pane chaiyo insolisation hunhu hwemudziyo uri kuedzwa. Mushandisi anofanira kusarudza iyo yakanyanya kukodzera zvinodiwa bvunzo.
Pfungwa bvunzo: Iyi bvunzo yakakodzera kune zvishandiso zvine madiki kana asina hanya ekugona, sekusaita kweropa pfupi.
Iyo bvunzo voltage inoiswa mukati menguva pfupi, kusvika pakuverenga kwakagadzikana kwasvika, uye iyo yekuyedza voltage inogona kuiswa mukati menguva yakatarwa nguva (kazhinji masekondi makumi matanhatu kana mashoma). Kuunganidza kuverenga pakupera kwebvunzo. Nezve marekodhi ezvakaitika kare, girafu dzichakweverwa zvichibva pane nhoroondo dzenhoroondo dzekuverenga. Iko kucherechedzwa kwehunhu kunoitwa kwenguva yakati rebei, kazhinji makore akati wandei kana mwedzi.
Iyi quiz inowanzoitwa yequizzes kana nhoroondo yezvakaitika kare. Shanduko mukushisa uye humidyity inogona kukanganisa kuverenga, uye muripo unodikanwa kana zvichidikanwa.
Kutsungirira bvunzo: Iyi bvunzo yakakodzera kufungidzira uye kudzivirira kudzivirirwa kwekutenderera kwemuchina inotenderera.
Tora kuverenga zvinoteedzana pane imwe nguva (kazhinji maminetsi ese mashoma) uye enzanisa mutsauko mukuverenga. Kukurudzira kunoshamisa kucharatidza kuwanda kwekuwedzera mukukosha kwekupokana. Kana kuverenga kwakadzika uye kuverenga hakuwedzere sekutarisirwa, iyo insolance inogona kunge isina kusimba uye ingangoda kutariswa. Inyoro uye yakasvibiswa insthulators inogona kuderedza kudzivisa kuverenga nekuti ivo vanowedzera kuvhiringidza zvazvino panguva yekuedzwa. Chero bedzi pasina kukosha kwekudziya kwakakosha mumudziyo uri muyedzo, pesvedzero yekudziya pane bvunzo inogona kufuratirwa.
Polarization Index (PI) uye Didilectric Kubatanidza Ratio (Dar) anowanzoshandiswa kujekesa mhedzisiro yemuedzo unodzivirira nguva.
Polarization Index (PI)
Iyo polarization index inotsanangurwa seyero yehuwandu hwekudzivisa kukosha mumaminitsi gumi kune kukosha kwekupokana mu1 miniti. Zvinokurudzirwa kuseta kukosha kwePi kweAc uye DC ekutenderera pakupisa kwekirasi b,
Ongorora: Dzimwe itsva dzekusimbisa masisitimu inopindura nekukurumidza kune insolation bvunzo. Ivo vanowanzotanga kubva pane bvunzo muedzo muGω range, uye iyo pi iri pakati pe1 ne2. Mune zviitiko izvi, iyo yekuverenga iyi, iyo yekuverenga iyo inogona kuregeredzwa. Kana iyo insolation kupokana yakakwira kupfuura 5Gω mω mu1 miniti, iyo yakaverengerwa pi inogona kunge isingarevi.
Nhanho voltage bvunzo: Iyi bvunzo inonyanya kubatsira kana iyo yekuwedzera voltage yemushini yakakwira kupfuura iyo inowanikwa bvunzo voltage yakagadzirwa neInternational Resserance Tester.
Zvishoma nezvishoma shandisa mazinga akasiyana-siyana eVoltage kune mudziyo uri pasi pekuedzwa. Iyo Yakakurudzirwa Test Voltage Ratio ndi1: 5. Iyo nguva yekuyedzwa yedanho rega rega ndiyo yakafanana, kazhinji makumi matanhatu masekondi, kubva pasi kusvika kumusoro. Iyi bvunzo inowanzoshandiswa pane bvunzo voltage yakaderera pane iyo yekuwedzera voltage yemushini. Kuwedzerwa kwekuwedzera kweyekuyedzana voltage mazinga kunogona kukonzera kushushikana kwekuwedzera pane insulation uye kushayikwa zvikanganiso, zvichikonzera kuderera kuramba tsika.
TEST Voltage Sarudzo
Sezvo iyo insolation kupokana bvunzo ine yakanyanya dctasi, inodiwa kusarudza yakakodzera bvunzo dzekutya kuti udzivise kushushikana zvakanyanya pakupenga, izvo zvinogona kukonzera kutadza kwekutadza. Iyo bvunzo voltage inogonawo kuchinja zvinoenderana nezvinodiwa nedzimwe nzira.
