Acereare Electric mndandanda watsopano wa ARM5 wopumira pawiri wa pulasitiki

I. Chidule cha malonda

ARM5 mndandanda wowumbidwa wawiri-break circuit breaker ndi chinthu chatsopano chomwe chapangidwa kumene ndi kampani yathu. Mapangidwe ake amawonetsa ukadaulo waposachedwa kwambiri wochepetsera komanso ukadaulo wopanga, ndipo ali ndi compact, modular, high breaking, zero arcing, zobiriwira komanso zoteteza chilengedwe. Wowononga dera ndi oyenera AC 50Hz / 60Hz dera ndi oveteredwa kutchinjiriza voteji 1000V, pazipita oveteredwa ntchito voteji 690V, pazipita kuswa mphamvu icu ndi ics mpaka 200kA ndi oveteredwa panopa kuchokera 32A kuti 630A kupanga, kuswa ndi kunyamula oveteredwa panopa, ndipo imatha kuteteza modalirika mizere ndi zida zamagetsi ngati zikuchulukirachulukira, kuzungulira kwafupipafupi komanso kutsika kwamagetsi. Itha kugwiritsidwanso ntchito pakuyambira kosawerengeka, kuchulukirachulukira, kuzungulira kwafupipafupi komanso kutetezedwa kwa injini.

II. Ubwino wazinthu / malo ogulitsa

1. Mndandanda wa ARM5 wapititsa patsogolo kudalirika kwa magetsi, ndipo uli ndi ubwino wa modularization, kukula kwazing'ono, kuphulika kwakukulu, kuthamanga kwafupipafupi, kudalirika kwakukulu, chitetezo chabwino cha chilengedwe, ntchito zambiri, ndi zina zotero.

2. yochepa-dera kuswa mphamvu pa AC400V, L mtundu: 100KA, M mtundu: 150KA, H mtundu: 200KA. 100KA imagwiritsidwa ntchito pazofunikira zogwira ntchito kwambiri, mizere yopanga mafakitale, ndi zida zazikulu zamagetsi. 150KA-200KA ili ndi kuthekera kotsogola kwamakampani ndipo ingagwiritsidwe ntchito m'makampani olemera komanso mafakitale apadera.

3. Mndandanda wa zowonjezerazi ukhoza kuikidwa mosavuta mu malo ogwirizana ndi ophwanya dera ndikukhala ndi ntchito yodalirika yogwira ntchito. Kutulutsidwa kwa shunt, kutulutsidwa kwa undervoltage ndi kulumikizana kothandizira zonse zimapangidwa kukhala ma module osiyana.

4. Kutulutsa kwamphamvu kwa maginito kwa ARM5-160, 250, 400 ndi 630 ma circuit breakers kungasinthidwe kuti akwaniritse zofunikira zachitetezo.

Ⅲ. Kumasulira kwachitsanzo

D: Chitetezo chogawa mphamvu; MA: chitetezo chamoto
Zovoteledwa panopa
TM: kutulutsidwa kwa thermomagnetic
Makhazikitsidwe achitetezo chochulukira amatha kusintha 1, ndipo mtengo wachitetezo chachifupi ndi wosinthika kapena wokhazikika 2;

I. Kumasulidwa

II.Thermal chitetezo zochita makhalidwe a matenthedwe maginito kumasulidwa kwa chitetezo kugawa

III. Mawonekedwe achitetezo chamafuta amtundu wamafuta otulutsa maginito achitetezo chagalimoto

Ntchito zazikulu ndi mawonekedwe

I. Chipangizo chotetezera mpweya

Dongosolo likasweka ndi mphamvu yayikulu, mpweya mu bokosi lolumikizirana umakanikizidwa mwachangu, ndipo chipangizo chachitetezo cha pneumatic chimasinthiratu latch yogwirira ntchito pansi pamphamvu yamphamvu ya mpweya, kuchepetsa kwambiri kuwonongeka kwa magetsi ndi mabasi ena.

Kupanga kwamphamvu kwamagetsi:zamakono zimayenda kudzera muzitsulo zokhazikika kuti zipange gwero lamagetsi, lomwe limapanga annular magnetic field arc ndi chitsulo chachitsulo ndipo mwamsanga amalowa m'chipinda chozimitsa cha arc pansi pa mphamvu ya maginito, yomwe imathandizira kuti iwonongeke mwamsanga.

Kapangidwe koyenera ka zolumikizana zosunthika kumapangitsa kuti nsonga zazifupi zazifupi ndi mphamvu zazinthu izi kukhala zocheperako kuposa momwe amayembekezera.

Mfundo yogwirira ntchito: pompopompo imayenda kuchokera ku cholumikizira chokhazikika 1, imachokera ku cholumikizira chokhazikika 2 kudzera pakuyenda, kukhudzana ndi siliva komanso kukhudzana kosuntha. Kulumikizana kosunthika kumadula mwachangu pansi pa mphamvu yamphamvu yothamangitsa magetsi (mphamvu ya Holm ndi mphamvu ya Lorentz) kuti ipititse patsogolo kuthamanga.

Mapangidwe a mpweya: pamene dera lalifupi lalikulu lamakono likuchitika pozungulira, mbali zopangira mpweya zimapangira mpweya wina pansi pa kutentha kwa arc, kuthamanga kwa mpweya mu bokosi la unit unit kumakula mofulumira, ndipo kutuluka kwa mpweya wothamanga kwambiri kungathe. kupangidwa kupyolera mu mpweya wotuluka wa chipinda chozimitsira arc, chomwe chingathe kuzimitsa arc.
