Iimeko Zokusebenza Eziqhelekileyo kunye Neemeko Zokufaka

● Umda ophezulu wobushushu bomoya ojikeleze umhlaba awuzukudlula +40℃, umda ophantsi awuzukudlula -5℃, kwaye ubushushu obuqhelekileyo beeyure ezingama-24 abuzukudlula +35°C;

● Ukuphakama kwendawo yokufakela akufuneki kudlule kwi-2000m;

● Umswakama ohambelanayo womoya awudluli kwi-50% xa ubushushu bomoya obuphakathi buyi-+40℃, kwaye umswakama ophezulu ohambelanayo uphantsi kubushushu obuphantsi. Umzekelo, yi-90% kwi-+20℃. Kufuneka kuthathwe amanyathelo akhethekileyo okufunxa okwenzeka ngamanye amaxesha kwimveliso ngenxa yotshintsho lobushushu;

● Xa kudityaniswa iingcingo, ipali echanekileyo yombane kufuneka iqhagamshelwe kwipali echanekileyo ye-circuit breaker, kwaye i-negative extreme mayiqhagamshelwe kwipali engalunganga ye-circuit breaker. Uqhagamshelo olubuyela umva aluvumelekanga;

● Inqanaba longcoliseko: Inqanaba lesi-2;

● Iimeko zokufakelwa: Zifakwe kwindawo engenampembelelo ibalulekileyo, ukungcangcazela, nakwindawo engenangozi (ukuqhuma);

● Indlela yokufaka: Ukusebenzisa ireyile yokufakela ye-TH35-7.5;

●Udidi lofakelo: UdidiⅡ, UdidiⅢ.

Ulwahlulo lweMveliso

☐ Ngokwenani leepali: 1P, 2P, 3P4P;

☐Ngokwemo yangoku yokukhubeka ngokukhawuleza: Uhlobo C (8ln±20%), Uhlobo D(12In±20%);

☐ Ngokwe-current elinganisiweyo: 6A, 10A, 16A, 20A, 25A, 32A, 40A, 50A kunye ne-63A;

☐Ngokwe-voltage yokusebenza elinganisiweyo: 125V/250V DC(1P), 250V/500V DC(2P), 300V/750V DC(3P), 500V/1000V DC(4P).

Idatha yoBugcisa ephambili

● Iimpawu zokuhamba nge-overcurrent Xa i-circuit breaker ifakelwe phantsi kweemeko eziqhelekileyo kunye nobushushu obuphakathi (30-35℃), i-overcurrentiimpawu zohambo ziyahambelana nemimiselo yeTheyibhile 1.

●Umthamo wokuqhekeka kwesekethe emfutshane olinganisiweyo we-circuit breaker uboniswe kwiTheyibhile 2.

Ubomi bombane boomatshini:

I-circuit breaker phantsi kwe-voltage echaziweyo, vula kwaye uphule i-current elinganisiweyo, amandla yi-0.85 ~ 0.9, uvavanyo lwe-cyde olusebenzayo luphindwe ka-120 ngeyure (>32A) okanye amaxesha angama-240 (≤32A), ubomi bayo boomatshini kunye nombane buphindwe ka-10000, ubomi bombane DC buphindwe ka-1500.

Ulwakhiwo:

Isixhobo sokwaphula isekethe siquka inkqubo yoqhagamshelwano, inkqubo yokucima i-arc, inkqubo ye-electromagnetic, indlela yokukhubeka, indlela yokusebenza kunye nendlu.

Umgaqo wokusebenza:

Phantsi kweemeko zokusebenza eziqhelekileyo, tsala indlela yokusebenza, ngeli xesha ukukhululwaindlela yokusebenza itshixiwe, kwaye oonxibelelwano abatshintshatshintshayo nabangazinzanga bayaqhagamshelana ukuze umbane uqhagamshelwe.

Xa umgca ugcwele kakhulu, iphepha le-bimetal lenkqubo ye-electromagnetic livelisa ukuguquguquka, lityhala isitshixo ukuze likhulule indlela yokusebenza, kwaye lishukumise unxibelelwano ukuze lukhuphe kwaye lunqumle umbane. Xa isekethe imfutshane, inkqubo ye-electromagnetic itsala isiseko sesinyithi, kwaye intonga ephezulu yesiseko sesinyithi ityhala isitshixo ukuze senze indlela yokusebenza ikhululeke, igqibezela umsebenzi wokukhusela ukuqhekeka kwesekethe.
