Munguva ye AC test voltage, iyo inowanzo shandiswa chikamu chekuyeresa yekuyera maitiro ndeaya anotevera:
(1) Muenzaniso pretreatment
Pamberi pekuyedzwa, sampu inofanirwa kuverengerwa zvinoenderana nemirairo yakakodzera:
1. Chengetedza pamusoro pechigadzirwa chekuedza chakachena uye chakaoma kudzivirira masikweya emunharaunda anokonzerwa nehunyoro kana kusvibiswa panzvimbo inodzivirira.
2. Mukushayikwa kwezvinodiwa zvakakosha, sampu inofanirwa kunge iri pane ambient tembiricha panguva yekuedzwa.
3. Mushure mekare chema mechanical, thermal kana magetsi chiito, chigadzirwa chekuedza chinofanira kusara kwenguva yakati pamberi pekuedzwa, kuitira kuti kuderedze simba rezvinhu zviri pamusoro apa pamigumisiro yekuedza.
(2) Tarisa chikamu chekubuda kwechikamu cheyedzo yedunhu pachayo
Usabatanidze chigadzirwa chekuyedza kutanga, asi shandisa voltage kudunhu rekuyedza.Kana pasina chikamu chekubuda chinoitika pasi peyedzo voltage yakakwira zvishoma pane chigadzirwa chebvunzo, dunhu rekuyedza rinokwanisa;kana iyo chikamu chekukanganisa chikamu ichidarika kana kusvika pachiyero chinobvumidzwa chekuburitsa chechigadzirwa chebvunzo 50% yeukoshi, kwainobva kupindira kunofanirwa kuzivikanwa uye matanho anotorwa kudzikisa mwero wekukanganisa.
(3) Kugadziriswa kweiyo test loop
Chiridzwa chiri mudunhu rekuyedza chinofanirwa kuverengerwa nguva nenguva chisati chadzvanywa kuti chitarise chiyero chechiyero chedunhu rekuyedza kana chigadzirwa chebvunzo chakabatana.Iyi coefficient inobatwa nemaitiro edunhu uye capacitance yechigadzirwa chebvunzo.
Pasi pe calibrated circuit senitivity, cherechedza kana pane kupindira kukuru kana simba re-high-voltage risina kubatanidzwa kana mushure mokunge magetsi emagetsi akabatanidzwa, uye kana zvakadaro, edza kuibvisa.
(4) Kutemerwa kwechikamu chekuyerera kwekutanga voltage uye yekudzima voltage
Bvisa iyo calibration mudziyo uye chengetedza imwe wiring isina kuchinjika.Kana iyo waveform yevoltage yekuyedza inosangana nezvinodiwa, vhezheni inowedzerwa kubva pamhepo iri pazasi peinotarisirwa chidimbu chekuburitsa simba rekutanga, uye voltage inosimudzwa nekumhanya kwakatarwa kudzamara simba rekuburitsa rasvika pamutengo wakatarwa.Iyo voltage panguva ino ndiyo chikamu chekubuda kwekutanga voltage.Zvadaro magetsi anowedzerwa ne10%, uye ipapo magetsi anodzikiswa kusvikira simba rekubuda rakaenzana nepamusoro-yakataurwa kukosha, uye iyo inopindirana ndiyo kudzima kwechikamu chekubuda.Pakuyera, iyo voltage yakashandiswa haibvumidzwe kudarika yakatemerwa inomira voltage yechinhu chekuyedza.Uye zvakare, kudzokororwa kushandiswa kwemagetsi padyo nayo kunogona kukuvadza chinhu chekuyedza.
(5) Edza kubuda kwechidimbu pasi peiyo yakataurwa bvunzo voltage
Zvinogona kuonekwa kubva pamusoro apa kuti parameters inoratidzira chidimbu chekubuda zvose zvinoyerwa pane chaiyo voltage, iyo inogona kunge yakakwirira kudarika chikamu chekubuda kwekutanga kwemagetsi.Dzimwe nguva zvinotemerwa kuyera simba rekuburitsa pasi peakati wandei bvunzo voltages, uye dzimwe nguva zvinotemerwa kuchengetedza imwe nguva pasi peimwe bvunzo voltage uye kuita zviyero zvakawanda kuti utarise maitiro ekukura kwekubuda.Paunenge uchiyera vhoriyamu yekuburitsa, inogona zvakare kuyera huwandu hwekubuda, avhareji yekuburitsa ikozvino uye mamwe maparamita ekuburitsa.
1. Kuyera pasina pre-applied voltage
Munguva yekuyedzwa, voltage pamuenzaniso inowedzerwa zvishoma nezvishoma kubva pamutengo wakaderera kusvika kune yakakosha kukosha, uye inochengetwa kweimwe nguva yenguva isati yayera kubuda kwechidimbu, wozodzikisa voltage uye nekucheka magetsi.Kuyerera kwakasarudzika dzimwe nguva kunoyerwa panguva yevoltage ramp-up, ramp-down, kana mukati menguva yese yekuyedza pane yakataurwa voltage.
2. Kuyera ne-pre-applied voltage
Munguva yekuyedzwa, voltage inowedzerwa zvishoma nezvishoma kubva pamutengo wakaderera, uye mushure mekudarika iyo yakatarwa chikamu chekuburitsa bvunzo voltage, inokwira kune yakagara yaiswa voltage, inoichengeta kweimwe nguva yenguva, yobva yadonha kune yekuyedza voltage kukosha, inochengetedza nguva yakatarwa yenguva, uyezve inoyera pane imwe nguva yenguva yekubuda muchidimbu.Munguva yese yekushandiswa kwevoltage, kutarisisa kunofanirwa kubhadharwa kune kusiyanisa kwechikamu chekuburitsa huwandu.
