I. Isishwankathelo semveliso
Uchungechunge lwe-ARM5 olubunjiweyo lwetyala eliphindwe kabini lekhefu lesekethe yimveliso entsha esandula ukuphuhliswa yinkampani yethu. Uyilo lwayo lubonisa umgaqo wangoku wokukhawulela kunye neteknoloji yokuvelisa, kwaye ine-compact, imodyuli, i-high breaking, i-zero arcing, i-green kunye neempawu zokukhusela indalo. I-breaker circuit ifanelekile kwi-AC 50Hz / 60Hz yesekethe kunye ne-voltage elinganisiweyo ye-insulation ye-1000V, i-voltage esebenzayo ephezulu ye-690V, i-icu ephezulu yokuqhaqha i-icu kunye ne-ics ukuya kwi-200kA kwaye ihlelwe ngoku ukusuka kwi-32A ukuya kwi-630A ukwenza, ukuphuka kunye nokuthwala i-current rated current, kwaye inokukhusela ngokuthembekileyo imigca kunye nezixhobo zombane kwimeko yomthwalo ogqithisiweyo, isiphaluka esifutshane kunye ne-undervoltage. Ingasetyenziselwa ukuqalisa okungaqhelekanga, ukulayisha ngaphezulu, isiphaluka esifutshane kunye nokukhuselwa kwe-undervoltage yemoto.
II. Iinzuzo zemveliso / amanqaku okuthengisa
I-1. Uchungechunge lwe-ARM5 luye lwaphucula ngakumbi ukuthembeka kokunikezelwa kwamandla, kwaye ineenzuzo zokumodareyitha, ubungakanani obuncinci, umthamo ophezulu wokuqhawula, i-arcing emfutshane, ukuthembeka okuphezulu, ukukhuselwa kokusingqongileyo okulungileyo, imisebenzi ebanzi, njl.
2. i-short-circuit breaking capacity kwi-AC400V, uhlobo lwe-L: 100KA, uhlobo lwe-M: 150KA, uhlobo lwe-H: 200KA. I-100KA isetyenziselwa izicelo ezineemfuno eziphezulu zokusebenza, imigca yemveliso yoshishino, kunye nezixhobo eziphambili zombane. I-150KA-200KA inamandla okuqhawula ishishini kwaye ingasetyenziswa kwishishini elinzima kunye neshishini elikhethekileyo.
3. Olu chungechunge lwezixhobo lunokufakwa ngokufanelekileyo kwindawo ehambelanayo ye-breaker circuit kwaye ibe nokusebenza okuthembekileyo okusebenzayo. Ukukhutshwa kwe-shunt, ukukhutshwa kwe-undervoltage kunye noqhagamshelwano oluncedisayo zonke zenziwe kwiimodyuli ezahlukeneyo.
4. Ukukhutshwa kwe-thermal magnetic ye-ARM5-160, i-250, i-400 kunye ne-630 i-circuit breakers inokulungelelaniswa ukuhlangabezana neemfuno zokukhusela.
Ⅲ. Khupha inkcazo yemodeli
D: Ukukhuselwa kokuhanjiswa kwamandla; MA: ukhuseleko lwemoto
Ikalwe ngoku
TM: ukukhululwa kwe-thermomagnetic
Ukumiselwa kokhuseleko lomthwalo ogqithisiweyo kulungelelaniswa i-1, kwaye ixabiso lokumisela lokukhusela i-short-circuit lihlengahlengiswa okanye lilungiswe i-2;

Imisebenzi ephambili kunye neempawu
I. Isixhobo sokukhusela umoya
Xa isiphaluka siphula ngamandla amakhulu, igesi kwibhokisi yeyunithi yoqhagamshelwano ixinzezeleka ngokukhawuleza, kwaye ifowuni yokukhusela i-pneumatic iguquguquka ngokukhawuleza i-latch yendlela yokusebenza phantsi koxinzelelo lomoya oqinileyo, ukunciphisa kakhulu umonakalo wokuphulwa kwangoku kwamanye amacandelo ombane kunye neebhasi.
Uyilo lwemagnethi yokuvuthela:i-current flow through the fixed contact ukuvelisa umthombo we-electromagnetic, eyenza i-annular magnetic field arc kunye nentsimbi yentsimbi kwaye ingene ngokukhawuleza kwigumbi lokucima i-arc phantsi kwesenzo sommandla wamagnetic, okulungele ukuphula ngokukhawuleza okwangoku.
Uyilo olufanelekileyo lolwakhiwo lomfowunelwa ohambayo kunye nolusisigxina lenza ixabiso eliphakamileyo lesekethe emfutshane kunye namandla kolu luhlu lweemveliso I²t ibencinci kakhulu kunokulindelekile.
Umgaqo osebenzayo: i-current flowing in from fixed contact 1, iphuma kwi-contact esisigxina ye-2 ngokusebenzisa i-contact eshukumayo, esisigxina yesilivere kunye noqhagamshelwano oluhambayo. Uqhagamshelwano oluhambayo luqhawula ngokukhawuleza phantsi kwesenzo samandla ombane anamandla (i-Holm force kunye ne-Lorentz force) ukuphucula isantya sokuphuka.
Uyilo lokuvuthuza komoya: xa isiphaluka esifutshane sangoku esikhulu senzeke kwisekethe, iindawo ezivelisa igesi ziya kuvelisa enye igesi phantsi kobushushu obuphezulu be-arc, uxinzelelo lomoya kwibhokisi yeyunithi yoqhagamshelwano lwanda ngokukhawuleza, kunye nokuhamba komoya okuhamba ngesantya esiphezulu. yenziwe nge-outlet yomoya yegumbi lokucima i-arc, elinokucima ngokufanelekileyo i-arc.
