• Ineempawu zokunxibelelana okuthembekileyo kunye nesekethe evulekileyo yexesha elide.

3. Iimeko zokusetyenziswa

• Indlela yokufaka: ukufakwa okusisigxina, ukufakwa kweflange;
• Indlela yokuvala ubushushu: iipali ezintathu;
• Ifanelekile kwi-AC 50Hz, i-voltage yokwambathisa elinganiselweyo yi-630V ~ 690V, i-current elinganiselweyo yi-60A ~ 1000A.

Ububanzi besicelo

I-MCBiziphuli zesekethe ezincincizisebenza ikakhulu kwindawo yokungena kunye neyokuphuma kwiinethiwekhi ezahlukeneyo zokusasaza, kuquka:

• Isekethe yokusasazwa kwezibane.
• Isebenza kwinkqubo yokusasazwa kwamandla njengokhuseleko lokugqithisa kakhulu kunye nokujikeleza okufutshane kwemigca;
• Isebenza kuzo zonke iintlobo zokukhusela ukuqala kwemoto kunye nokukhusela iibhuleki.
• Isebenza kulawulo lweenkqubo zokusetyenziswa kombane, ezifana nokukhanyisa, umabonwakude, ifowuni kunye nekhompyutha;
• Isebenza kwiindawo ezingatshintshwa rhoqo okanye ezingasetyenziswa rhoqo kumacandelo.
• Isetyenziswa kakhulu kukhuseleko lomgca (ukhuseleko olugqithisileyo), kwaye inika umsebenzi wokukhusela wokunqumla ngokukhawuleza umsinga wempazamo kwisiphako se-short-circuit kwisekethe;
• Ingasetyenziswa njengezixhobo zokuqala iimoto kunye neziqhoboshi;
• Ingasetyenziselwa ukhuseleko lombane olugqithisileyo nolwe-short circuit;
• Ingasetyenziselwa ukukhusela i-motor kunye ne-transformer kwi-overload kunye ne-undervoltage.

Iimeko Zokusebenzisa

• 1, Ubushushu bomoya obujikeleze umhlaba abuyi kudlula + 40 ℃, kwaye abuyi kuba ngaphantsi kune - 5 ℃, umswakama ohambelanayo awuyi kudlula i-90%, kwaye umswakama ophezulu ohambelanayo uyavunyelwa kubushushu obuphantsi;
• 2, Iqondo lobushushu lomoya ojikelezileyo aliyi kuba ngaphezulu kwe + 40 ℃;
• 4, Ukuphakama kwendawo yokufakela akuyi kudlula i-2000m;
• 5, Kwindawo ephakathi engenangozi yokuqhuma, kwaye kwindawo ephakathi akukho gesi okanye umphunga owaneleyo wokugqwala iintsimbi nokutshabalalisa ubushushu;
• 6, Akukho kungcangcazela okunobudlova, impembelelo okanye utshintsho oluqhelekileyo.
• 9, Isixhobo sokwaphula isekethe kunye nesixhobo sokufaka umhlaba zingafakelwa kwaye ziqhagamshelwe ngokwemiyalelo yomenzi okanye ngokweenkcazo zemveliso;
• 10, I-circuit breaker ingasetyenziswa kunye nezikhuseli zokuvuza ezinepali enye kunye neepali ezininzi ezifakwe kuyo ukwenza isixhobo sokukhusela ukuvuza esidibeneyo.

Ukufakwa kweentambo kunye namanyathelo okhuseleko

1. Indawo yokufakela:

Ubushushu bomoya ojikeleze umhlaba kufuneka bube phakathi kwe-5 ℃ ukuya kwi-40 ℃, ngokubanzi akufuneki budlule kwi-+35 ℃; ubushushu obuphakathi beeyure ezingama-24 abufanele budlule kwi-+35 ℃, kwaye umswakama womoya ojikeleze umhlaba akufuneki udlule kwi-50%.

2. Indawo yokufakelwa:

Xa i-circuit breaker ifakelwe kwicala lokungena kwamandla, isiphelo seswitshi se-circuit breaker kufuneka sisekelwe ngokuthembekileyo, kwaye ukumelana nobushushu phakathi kwe-circuit breaker kunye nesakhelo sesinyithi esisekelwe phantsi kufuneka kube ngaphezu kwe-1000MΩ;

Xa i-circuit breaker ifakelwe kwicala lokungena kwamandla, ayinakuxhonywa;

3. Imiqathango yokusetyenziswa:

Isixhobo sokwaphula isekethe kufuneka sifakwe kumphezulu wokufakelwa othe tye okanye othe nkqo. Ukuba le mfuneko ayinakufezekiswa ngenxa yokuthintelwa kwendawo yokufakelwa, la manyathelo alandelayo anokuthathwa:

(1) Izixhobo zokunxibelelana ezincedisayo mazibekwe kwiindawo ezifanelekileyo kwibhodi yesiphelo somsasazi wangaphambili we-circuit breaker.

Ufakelo oluqhelekileyo 3 ~ 4. Xa i-circuit breaker ingasebenzi kakuhle, inokusekelwa ngokuthembekileyo ngokusebenzisa unxibelelwano oluncedisayo.
