Pane mukana wakadini wekuti transformer ine frequency yakaderera ikundikane?
Mikana yekukundikana inosiyana zvichienderana nenzvimbo.
Shandisa multimeter kuyera mhando ye transformer ine frequency yakaderera
1.Kuonekwa zvakananga negear capacitive
Mamwe ma multimeter edhijitari ane basa rekuyera capacitance, uye zviyero zvawo zvekuyera i2000p, 20n, 200n uye 2 μ Uye 20 μ Giya rechishanu. Panguva yekuyera, mapini maviri e capacitor yakaburitswa anogona kuiswa zvakananga muCx jack pabhodhi remita. Mushure mekusarudza range yakakodzera, data rekuratidzira rinogona kuverengwa uye transformer inogona kutongwa.
2. Tsvaga nemidziyo yekudzivirira
Maitiro ekuchaja e capacitor anogonawo kuonekwa ne digital multimeter, iyo inoratidza shanduko ye voltage yekuchaja nehuwandu hwe digital hwakasiyana. Kana chiyero chekuyera che digital multimeter chiri n times/second, saka panguva yekutarisa maitiro ekuchaja e capacitor, kuverenga kwe n kwakazvimirira uye kunowedzera zvinoteedzana kunogona kuonekwa sekondi yega yega. Zvichienderana nechinhu ichi chekuratidzwa kwe digital multimeter, mhando ye capacitor inogona kuonekwa uye capacitance inogona kufungidzirwa.
Cherechedza: Nheyo yekuona uye nzira yekuona zvakafanana kune transformer ine mafrequency akakwira uye transformer ine mafrequency akaderera.
Kugadziriswa Kwezvikanganiso zveLow Frequency Transformer
Kupatsanura uye zvikonzero zvezvikanganiso zvakajairika mu transformers
(1) Matambudziko aripo kana transformer yasvika. Zvakadai semagumbeze asina kusimba, mabhuroko emuchina asina kusimba, welding isina kunaka, insulation isina kunaka yemukati, simba rema "short circuit" risina kukwana, nezvimwewo.
(2) Kukanganiswa kwemitsara. Kukanganiswa kwemitsara ndicho chinhu chinonyanya kukosha pazvinhu zvese zvinokonzera tsaona dzetransformer. Zvinosanganisira: over voltage inogadzirwa panguva yekuvhara, voltage peak muchikamu chidiki chemutoro, line fault, flash over nezvimwe zviitiko zvisina kujairika. Rudzi urwu rwefault runotora chikamu chikuru mu transformer faults. Saka, bvunzo yekudzivirira impulse inofanira kuitwa pa transformer nguva nenguva kuti ione simba re transformer pakurwisa inrush current.
(3) Kukurumidza kukwegura kwetransformer insulation kunokonzerwa nekushandiswa zvisina kunaka kunowedzera. Avhareji yehupenyu hwebasa hwetransformer imakore 17.8 chete, izvo zvakaderera zvikuru pane hupenyu hwebasa hunotarisirwa hwemakore 35-40.
(4) Kupisa kwemagetsi kunokonzerwa nekupfurwa nemheni.
(5) Kuwedzeredza. Kuwedzeredza kunoreva transformer iri kushanda kwenguva yakareba inopfuura simba rezita kwenguva yakareba. Kuwedzeredza kunowanzoitika kana chiteshi chemagetsi chikaramba chichiwedzera mutoro zvishoma nezvishoma, mudziyo wekutonhodza uchishanda zvisina kujairika, kukanganisa kwemukati me transformer, nezvimwewo, uye pakupedzisira kunoita kuti transformer iwedzere. Kupisa kwakanyanya kunokonzera kukwegura kwe insulation. Kana makadhibhodhi e insulation e transformer achikura, simba repepa rinoderera. Nokudaro, kukanganisa kwezvikanganiso zvekunze kunogona kukonzera kukuvara kwe insulation, izvo zvinogona kukonzera zvikanganiso.
(6) Kunyorovesa: kana paine mafashamo, kubuda kwepombi, kubuda kwemusoro, kupinda kwemvura mutangi remafuta riri padivi pechifukidziro kana zvimwe zvinhu, uye paine mvura mumafuta anodziisa, nezvimwewo.
(7) Kugadziriswa kwakakodzera hakuna kuitwa.
