Malo ogwiritsira ntchito bwino

● Kutentha kozungulira: -15 ~ 40 ℃, kutentha kwa tsiku ndi tsiku ≤+35 ℃;

● Chinyezi: Mtengo wapakati wa chinyezi choyezera mkati mwa maola 24 ndi ≤95%; mtengo wapakati wa

Kuthamanga kwa nthunzi wamadzi kuyeza mkati mwa maola 24 ndi ≤2.2kpa; pafupifupi mtengo wa chinyezi wachibale ndi

● Kutalika ≤1000m;

● Kuwala kwa dzuwa kunganyalanyazidwe;

● Kugwedezeka kuchokera kunja kwa switchgear ndi zida zowongolera zimatha kunyalanyazidwa;

● Mpweya wozungulira sungaipitsidwe kwambiri ndi fumbi, utsi, mpweya wotentha kapena woyaka, nthunzi kapena utsi.

◆Kapangidwe

Dera lalikulu la VEF-12GD mndandanda wamtundu wa 3 wogwirira ntchito wa vacuum circuit breaker imakonzedwa motalika. Mbali yakumtunda ndi chosinthira cholumikizira, chapakati ndi chopukutira dera, ndipo chapansi ndi chosinthira chapadziko lapansi. Makina ogwiritsira ntchito, makina oyendetsa dera ndi njira yolumikizirana ili kutsogolo kwa chosinthira. Chosinthiracho chikhoza kukhazikitsidwa mozondoka.

Chitetezo ndi zabwino kwambiriophatikizidwakulibe

Kudalirika kwakukulu, magwiridwe antchito okhazikika, mawonekedwe olimba, miniaturization, osasamalira, okonda zachilengedwe, komanso kukana kwamakina.

Zowoneka kusagwirizana otsegula kulankhula

Chosinthira cholumikizira chozungulira chokhala ndi maulumikizidwe otseguka owonekera mutatsegula.

Makina ogwiritsira ntchito modular

Wowononga dera amatenga makina ogwiritsira ntchito modular, omwe amatha kusinthidwa kapena kusinthidwa paokha, ndipo amatha kusinthana bwino. Itha kugwiritsidwa ntchito pamanja, kapena itha kuyendetsedwa ndi AC kapena DC yosungirako mphamvu kuti izindikire kuwongolera kwakutali.

Atatu-mitsinjentchito pang'onopang'ono, odalirika makina interlocking

Cholumikizira cholumikizira, chophwanya chigawo, ndi chosinthira chapadziko lapansi chimagwiritsidwa ntchito pa shaft imodzi motsatana, ndipo pali kulumikizidwa kwamakina pakati pa ma shaft atatu kuti apewe kusokoneza.

Mawaya akumapeto okhala ndi sensa yowonetsera yosalumikizana

Palibe capacitance, pogwiritsa ntchito ukadaulo wosalumikizana nawo, wotetezeka komanso wodalirika.

Khomo la kabati ndi chosinthira chapadziko lapansi amapangidwa ndi dongosolo lodalirika lolumikizirana

Kuonetsetsa chitetezo cha woyendetsa, khomo lopanda kusintha la kabati yokhala ndi chipika cha chitseko cha kabati.
