Umhloli wokumelana wokufakelwa angasetshenziswa ukukala inani lokumelana nezinto zokwakha ezahlukahlukene kanye nokumelana kwama-transformers, ama-motor, amakhebuli, imishini kagesi, njll. Ngezansi sizoxoxa ngezinkinga ezithile.
01
Kusho ukuthini ukuphuma okufushane-umjikelezo wamanje we-Insurtur Revance Peerter?
Izintambo ezinde, ama-motors anemimoya eminingi, abaguquli, njll. Bahlukaniswa njengemithwalo ye-capacitive. Lapho ulinganisa ukumelana kwezinto ezinjalo, okukhishwayo okufushane-umbuthano wamanje we-Insuration Reraction Tester angakhombisa ukumelana kwangaphakathi komthombo wangaphakathi okhipha amandla we-megger. .
02
Kungani usebenzise isiphetho sangaphandle "g" ukukala ukumelana okuphezulu
I- "G" esibulalayo (i-Shielting terminal) yengaphandle, umsebenzi wayo ukususa ithonya lomswakama kanye nokungcola endaweni yokuhlola emiphumeleni yokulinganisa. Lapho ulinganisa ukumelana okuphezulu, uma uthola ukuthi imiphumela kunzima ukuzinza, ungacabanga ngokusebenzisa i-G terminal ukuqeda amaphutha.
03
Ngaphezu kokulinganisa ukumelana, kungani kufanele silinganise isilinganiso sokulinganisa kanye ne-polarization inkomba?
Esivivinyweni sokufakelwa, inani lokumelana lokufakelwa ngesikhathi esithile alikwazi ukubonisa ngokugcwele izinzuzo nokubi komsebenzi wokufakelwa kwesampula yokuhlola. Ngakolunye uhlangothi, ngenxa yezinto ezibonakalayo zokufakwa komsebenzi ofanayo, ukumelana kokufakelwa kuvela lapho ivolumu inkulu, futhi ukumelana kokufakelwa kuvela lapho ivolumu incane. Omkhulu. Ngakolunye uhlangothi, impahla efaka ukufakwayo inenqubo yokufaka umkhawulo wenqubo (i-DAR) nenqubo ye-polarization (PI) ngemuva kokusebenzisa i-voltage ephezulu.
04
Kungani i-electronic inser yokumelana nokungamelana ne-electronic ikhiqize i-voltage ephakeme ye-DC ephezulu
Ngokomthetho wokuguqulwa kwe-DC, umhloli wokumelana we-elekthronikhi onikwe amandla amabhethri amaningana acutshungulwa yi-Booster Circuit. Amandla okuhlinzekwa kwamandla aphansi azokwandiswa akhuphuke ngokuphuma okuphezulu kwe-DC Voltage. Amandla kagesi aphezulu akhiqizwa aphezulu kepha amandla okukhipha aphansi.
Izindlela zokuphepha zokusebenzisa umhloli wokumelana wokufakelwa
1. Ngaphambi kokulinganisa, yenza isifunda esivulekile kanye nokuhlolwa kwesifunda okufushane kumhloli wokumelana wokufakelwa ukuze uhlole ukuthi ngabe umhloli wokumelana wokungena kokunye uvamile. Ukusebenza okuthize yilezi: Vula izintambo ezimbili zokuxhuma, isikhombisi sesibambo se-swing kufanele sikhombe ku-infinity, bese sifushane izintambo ezimbili zokuxhuma, isikhombisi kufanele sikhombe ku-zero.
2. Idivayisi evivinywa kufanele inqanyulwe kweminye imithombo yamandla. Ngemuva kokuqedwa kwesilinganiso, idivaysi evivinywayo kufanele ikhishwe ngokuphelele (cishe imizuzu emi-2 ~ 3) ukuvikela imishini nokuphepha komuntu siqu.

4. Ngesikhathi sokuhlola okuthuthumelayo, beka umhloli wokumelana wokufakelwa endaweni evundlile, futhi kungabikho mjikelezo esifushane phakathi kwezinkinobho zesifo esivunyelwe lapho isibambo sigingqika. Lapho uhlola ama-capacitors namakhekhe, kuyadingeka ukunqamula ukuxhumeka i-wiring lapho isibambo se-crank sigingqa, ngaphandle kwalokho ukushaja okubuyela emuva kuzolimaza umhloli wokumelana wokufakelwa.
5 Ngesikhathi senqubo yokubhukuda, lapho isikhombisi sesifinyelele ku-zero, ngeke sisakwazi ukuqhubeka nokuvimbela ukufudumeza nomonakalo kwikhoyili kuwashi.
I-6. Ukuze uvikele ukumelana okuvuzayo kwedivayisi ngaphansi kokuhlolwa, lapho usebenzisa umhloli wokumelana wokufakelwa, ungqimba oluphakathi lwedivayisi ngaphansi kokuhlolwa (njengokufakwa kwangaphakathi phakathi kwendandatho yokuvikela.
7 Ngokuvamile, ngemishini enamandla kagesi alinganiselwe ngaphansi kwama-volts angama-500, khetha umhloli wokumelana wokufakelwa kwama-volts angama-500 noma ama-1000 volts; Kwemishini enamandla kagesi alinganiselwe wama-volts angama-500 nangaphezulu, khetha umhloli wokumelana wokufakelwa kwama-1000 kuya ku-2500 volts. Ekukhetheni isikali sebanga, ukunakekelwa kufanele kuthathwe ukungenzi isilinganiso sokulinganisa ngokweqile ngokweqile kwenani lokulwa nokufakwa kwemishini ngaphansi kokuhlolwa ukuze uvikele amaphutha amakhulu ekufundweni.
8. Vikela ukusetshenziswa kwabahloli bokumelana kokufakelwa ukukala ku-Lightnist Weather noma imishini eseduze enabaqhubi bamavoluna aphezulu.
