Ukukhetha umthwalo umshini: izeluleko kongoti

Ishintsha okuzenzakalelayo (emishinini yokuthenga) asetshenziswa ukuze bazivikele sindisa kanye isekhethi wamanje (CC) exhunywe kwi kagesi kubo. Esifushane wesifunda full wesifunda uyanikezwa kagesi asikiwe, overload wamanje - Ukuvikelwa ezishisayo. cutoff kagesi senziwa ngokushesha, Ukuvikelwa ezishisayo - ngemuva kwesikhathi esithile, esekelwe ubukhulu wamanje sindisa (lamanje kokuba value eyeqa zamanje ezingu umshini, wabonisa kwezezindlu yayo).

Ukwenza isinqumo esihle

Ngokuvamile kukhona isidingo uxhumano ezengeziwe kagesi (Ukushisa phansi, e. Pump futhi t. D.) Eqenjini ehlukile (okuzenzakalelayo). Kulokhu-ke kubalulekile ukukhetha umthwalo umshini. izibalo engalungile kungaholela ukwehluleka akhubeke Ukuvikelwa uma kwenzeka esiphuthumayo noma ukunqamuka njalo ngaphandle kwesizathu. Kukhethwa umshini umthwalo ukubala lihlanganisa ukusetshenziswa wamanje imishini axhunyiwe. Lokhu value ingatholakala idatha iphasiphothi. Uma idokhumenti iqukethe kuphela ukusetshenziswa kwamandla, lamanje kuyoba ulingana namandla ihlukaniswe ezingeni voltage (ifomula lula for single phase supply). In the ukungabikho imibhalo kwi-e-mail. imishini wamanje kungaba azimisele besebenzisa izibopho zamanje, noma yimuphi omunye e-mail. ekulinganiseni kudivayisi, isebenze kafushane imishini at zigcwele. Manje, ukwazi ukusetshenziswa wamanje kungaba azimisele ukalwe samanje umshini. It is ikhethiwe ekubalweni ukusetshenziswa, kodwa phezulu. Ngokwesibonelo, uma kuba 20 A, umshini kuyoba 25 A.

Ukubalwa iDemo wesifunda yamanje

Kukhethwa umshini umthwalo ukubala kuhlanganisa wamanje short circuit. Ukuze nokucupha umbandela kudinga ezidlula ezithile RS. Ukuze imishini ezahlukene kuthatha namanani ahlukene. amadivaysi Modern ube kophawu zabo omunye izinhlamvu: B, C noma D. B = 5, C = 10, D = 20. Lesi sibalo - Coefficient Wandisa samanje ezingu umshini. Okuningi ukubaluleka okuholela iyanda yi 1.1 (ukuphepha isici). Ngenxa yalokho, okukhipha value lapho umshini azosebenza. It uhlala ukucacisa ukubaluleka short wesifunda yamanje kweqiniso. Ngenxa yalesi kubalulekile ukukala ubukhulu impedance iluphu "Isigaba-zero" iphuzu uxhumano imishini. Khona-ke 220 (voltage ezingeni e volts) zihlukaniswe Inani lale ukumelana naso futhi kwenze uthola yangempela isekhethi zamanje. Kufanele kube esilingana noma sibe ngaphezu isekhethi ezithothene umshini.

Ukukhetha umthwalo umshini kuhambisana nezidingo ngenhla, njengoba umthetho, sihlinzekela operation evamile kudivayisi uma ezincane sindisa imisinga, kanye nokusebenza kwawo esimweni sindisa okubangelwa ukungasebenzi imishini axhunyiwe.

Uma umshini isivele isethiwe ...

Kanjani ukubala umthwalo emshinini ukuthi selivele likhona? Ngenxa yalesi kubalulekile ukunquma ubukhulu umthwalo ukusetshenziswa wamanje (njengoba kwenziwa - ezichazwe ngenhla). Akumele ledlula inani ngokulinganisa of umshini.

Uma uneminye nobunzima, futhi awukwazi wenze ukubala ngokuzenzekelayo umthwalo, kuyancomeka ukuba uthintane inhlangano ezikhethekile.
