Kupesana Kunopesana Tester kwakakodzera kuyera kukosha kwezvinhu zvakasiyana-siyana zvekushanduka kwevatange, midziyo yemagetsi, midziyo yemagetsi inoshanda mumamiriro ezvinhu emagetsi kuti udzivise kuvhundutsa magetsi, zvinokara uye zvishandiso Kukuvara.
Zvinetso zvakajairika zvekusimbisa kupokana tester ndizvo zvinotevera:
1. Kana kuyera mari yekukanganisa, chii chinonzi hukama pakati pechidimbu chipfupi-dunhu razvino rekupesana kupokana kuTester uye data yakayerwa, uye nei?
Saizi yeiyo inobuda pfupi-dunhu renzvimbo yekupokana kwekupesana tester inogona kuratidza saizi yekudzikisira kwemukati kweiyo yepamusoro-voltage sosi mukati meiyo megger.
Mazhinji misungo inonsulation inodaira mitoro yekuwana, senge tambo refu, motors ine mhepo nemhepo, uye shanduro. Naizvozvo, apo chinangwa chakayerwa chine chekuita, pakutanga kweiyo bvunzo yekuyedza, iyo yepamusoro-voltage sosi yekuparadzira inofanirwa kubhadharisa iyo capcitor kuburikidza nekupokana kwayo kwemukati, uye zvishoma nezvishoma kubhadharisa kuwanda kweiyo yekuwedzera-voltage yakabuda Insulation kuramba tester. . Kana kukosha kwekuziva kweiyo yakayerwa chinangwa yakakura, kana kuramba kwemukati kweiyo sosi yepamusoro-sosi yakakura, maitiro ekuchaja anotora nguva yakareba.
Kureba kwayo kunogona kutsanangurwa nechigadzirwa che r remukati uye c mutoro (unit: chechipiri), icho, t = r yemukati * c murimi.
Naizvozvo, panguva yekuedzwa, zvinodikanwa kubhadharisa mutoro wakadaro wechiitiko kune iyo bvunzo yekuverenga, I / c.
Naizvozvo, zvidiki zvekuramba kwemukati uye chikuru chekubhadhara chirimwa chiripo chazvino, chinokurumidza mhedzisiro yacho ichave yakagadzikana.
2. Ndeipi basa re "G" rutivi rwechitarisiko? Mune yakakwirira-voltage uye yakakwira-kupokana bvunzo nharaunda, nei zvichidikanwa kubatanidza iyo "G" terminal kunze?
Iyo "g" kupera kwemukati ndeyekuvhundutsa terminal. Basa remuchivhi rekuvhara riripo kubvisa pesvedzero yeushiviti uye tsvina munzvimbo yeyedzo pane chiyero mhedzisiro. Iyo yekunze "g" terminal inopfuura nekudzika kwechigadzirwa chazvino chechigadzirwa, kuitira kuti iregeji yazvino haipfuure mudunhu rekunze, uye inobvisa kukanganisa kunokonzerwa neiyo leakage yazvino. Iyo g terminal inoshandiswa kana uchiedza zvakanyanya.
Kazhinji, iyo g terminal inogona kutariswa pamusoro pekamusoro kupfuura 10G. Nekudaro, kupokana uku hakuna chokwadi. Kana ichinge yakachena uye yakaoma uye iyo vhoriyamu yechinhu chidiki idiki, inogona kuve yakagadzikana pasina kuyera 500g paG magumo. Mune zvakanyorovesa uye zvakasviba nharaunda, kukosha kwezasi kwekukosirwa kunodawo kunodawo kuti idzo idzo. Zvikurukuru, kana iwe ukaona kuti mhedzisiro yacho yakaoma kudzikamisa kana kuyera kupokana kwakanyanya, unogona kufunga nezvekushandisa iyo g terminal. Zvakare cherechedza kuti iyo yekuchengetera terminal g haina kubatana neyekuchengetera dura, asi kune iyo insulator pakati pe l uye e kana kune waya yakasarudzika-isina kuedzwa.
3 Ndeipi pfungwa?
Pi ndiyo indekisi yepolarization, iyo inoreva kuenzanisa pakati peiyo insulation kudzikisira kwemaminitsi gumi uye iyo insolation kuramba kweminiti 1 panguva yekuedzwa kwechiedza;
Dar ndeye dielelectric yekutandarira chiyero, icho chinoreva kuenzanisa pakati pekunzwa kwekunzwa kwe1 miniti uye iyo insolation kuramba gumi neshanu panguva yekubvunzana kwemisangano;
Muchiitiko chekusimbirira, iyo insulation kupokana kukosha pane imwe nguva haigone kuratidza zvizere kuisana basa reiyo bvunzo yemuenzaniso. Izvi zvinokonzerwa nezvikonzero zviviri zvinotevera. Kune rimwe divi, kupokana kwekunamatira kweiyo basa rimwe chete rezvinhu zvekushandisa zvinhu zvidiki kana vhoriyamu yakakura. , Kupokana kwekusimbisa kunoonekwa kana vhoriyamu idiki. Kune rimwe divi, zvinyorwa zvekusimbisa zvine maitiro ekutora huwandu hwehuwandu hwekuputika uye maitiro ekupomhodza kweiyo mhosva mushure mekunge iyo yakakwira voltage yashandiswa. Naizvozvo, iyo Simba System inoda kuyerwa kwekunyora kweiyo ratio-iyo ratio yeRATEX uye rotio yeRations uye ratio, tambo, motoro uye dzimwe nguva dzakawanda, uye shandisa izvi Data kuti uone iyo insulation yakanaka kana yakaipa.
4. Nei iyo magetsi ekusimbisa kupokana tester kuburitsa yakakwira dc yakakwira voltage kana yakaiswa mabhatiri akati wandei? Izvi zvinoenderana neiyo nheyo ye dc kushandurwa. Iyo yepazasi yemagetsi yekuisa voltage inosimudzwa kune yakakwira yekubuda DC DC voltage kuburikidza neinosimudzira dunhu redunhu. Iyo yakakwira voltage yakagadzirwa yakakwira asi simba rekubuda idiki (simba rakaderera uye diki riripo).
Ongorora: Kunyangwe kana simba riri diki kwazvo, hazvikurudzirwe kubata pachedu kubata bvunzo probe, pachave nekunzwa kwekunzwa.
