Iyo Insulation Kupikisa Tester yakakodzera kuyera kukosha kwezvinhu zvakasiyana-siyana zvekushanduka kwevanochinja, midziyo yemagetsi yekuita kuti midziyo yemidziyo, dzinoshanda mumidziyo yakajairika uye kudzivirira tsaona dzakadai sekuvhunduka kwemagetsi kuwanda uye kukuvara kwemidziyo.
Matambudziko akajairika ekuvhiringidza kupesana tester ari seinotevera:
1. Kana kuyera mari yekukanganisa, chii hukama pakati pekubuda kwenguva pfupi-dunhu razvino rekupesana kupesana kuwanda uye data yakayerwa, uye nei?
Iyo yekubuda pfupi-dunhu razvino rezvipenga zvinopesana zvinopesana tester zvinogona kuratidza kupokana kwemukati kweiyo yepamusoro-voltage sosi.
Zvizhinji zvekushandisa bvunzo zvinhu zvakakura, senge tambo refu, motombo ane mhepo dzemhepo, shanduko dzinoyera, pakutanga kwemaitiro ekuverenga, iyo yakakwira vhatidziro muInternational Ristance Tester inofanira kubhadharisa Capacititor kuburikidza nekupokana kwayo kwemukati, uye zvishoma nezvishoma kunobhadharisa vhoriyamu kune zvakabudiswa zvakarukwa kukosha kwepamusoro kweiyo insulation kupokana kupikisa tester. Kana kukosha kwekuziva kwechinhu chakayerwa chakakura, kana kuramba kwemukati kweiyo yakakwira vhatage sosi yakakura, maitiro ekuchaja anotora nguva yakareba.
Kureba kwaro kunogona kutsanangurwa neiyo chigadzirwa che r uye c mutoro (mumasekondi), kureva t = r * c * c mutoro.
Naizvozvo, panguva yekuedzwa, mutoro wezvekutakura unoda kubhadharwa kuongororwa kweyedzo,
Naizvozvo, zvidiki zvekuramba kwemukati ndewekuti, iyo yakakura yekubhadhara iripo, uye nekukurumidza uye yakawandisa mhedzisiro yebvunzo.
2. Chii chiri basa re "G" Mugumo wechidyarwa? Munharaunda yebvunzo yeyekupedzisira voltage uye kupokana kukuru, nei chiridzwa chakabatana ne "g" terminal?
Iyo "G" yekupera kwechiridzwa ndeyechiridzwa terminal, iyo inoshandiswa kubvisa simba rekunyorova uye tsvina munzvimbo yekuedzwa pane iyo mhedzisiro. Iyo "G" yekuguma kwechiridzwa ndeyekupfuudza zvazvino pamusoro pechinhu chakaedzwa pachinhu chakaedzwa, zvekuti izvo zvazvino zvisina kuedzwa hazvipfuure nechiridzwa, kubvisa chikanganiso chakakonzerwa neyekudzima zvazvino. Kana uchiedza kukosha kwepamusoro-soro, iyo g yekupedzisira inoda kushandiswa.
Kazhinji, iyo G-terminal inogona kutariswa kana yakakwira kupfuura 10G. Nekudaro, kupokana uku hakuna mhedziso. Iyo yakachena uye yakaoma, uye huwandu hwechinhu chichayerwa zvidiki, saka zvinogona kuve zvakagadzikana pasina kuyera 500g paG End; Mumamiriro ezvinhu akanyorova uye akasviba, kuparadzira kwakaderera kunodawo g terminal. Zvikurukuru, kana zvikaonekwa kuti mhedzisiro yacho yakaoma kuva yakagadzikana paunenge uchiyera kuramba, iyo G-terminal inogona kutariswa. Mukuwedzera, zvinofanirwa kucherechedzwa kuti iyo yekuchengetedzeka terminal g haina kubatana neyekuchengetera dura, asi yakabatana neyekusaita pakati pe l uye e, kana mune yakawanda tambo yetamboti, kwete kune mamwe waya wa waya.

Pi ndiyo indekisi yepolarization, iyo inoreva kuenzanisa kwekusimbisa kwemukati mumaminitsi gumi uye 1 miniti panguva yekunzwa bvunzo;
Dar ndeye dielelectric yekutora ratio, iyo inoreva kuenzanisa pakati peiyo insulation kuramba muminiti imwe uye iyo muna 15s;
Muchiitiko cheInternational test, iyo insulation kupokana kukosha pane imwe nguva haigone kuratidza zvakazara kunaka kwesimbe yekusimbisa kwechinhu chebvunzo. Izvi zvinokonzerwa nezvikonzero zviviri zvinotevera: Kune rumwe rutivi, iyo insolation kuramba yakafanana neyekuita zvinhu zvidiki apo vhoriyamu yakakura, uye yakakura kana iyo vhoriyamu kana iyo vhoriyamu ishoma. Kune rimwe divi, pane kubhadharisa kusavimbika uye polarization maitiro mune zvekusimbisa zvinhu kana yakakwira voltage yashandiswa. Naizvozvo, iyo Simba System inoda kuti chiwedzerwe chiwande Iyi data.
4. Nei mabhatiri akati wandei ekusimbisa kwemagetsi kupokana tester gadzira yakakwira DC voltage? Izvi zvinoenderana neiyo nheyo ye dc kushandurwa. Mushure mekusimudzira redunhu kugadziriswa, iyo yepazasi yekuvhomora inomutswa kune yakakwira yekubuda DC DC voltage. Kunyangwe iyo yakagadzirwa yakakwira vhoti yakakwira, simba rinobuda idiki (simba rakaderera uye diki riripo).
Ongorora: Kunyangwe kana simba riri diki kwazvo, harikurudzirwe kubata bvunzo probe, kuchave kuchine kuchibata.
