Uyini oxhumana naye ophansi we-vacuum?
Avoltage ephansiUkuthophana kwe-vacuumIngabe inkinobho elawulwa ngogesi eyenzelwe ukwenza noma ukwephula umjikelezo wamandla ngaphansi komthwalo. Ukuphazamiseka kwe-VacuumUkucima ama-arc kwakhiwa lapho othintana nabo bevulwa, okwenza kube yinto elungele ukusebenza kaningi ezindaweni eziyinselele.
Imvamisa isetshenziswa kumasekethe kuze kube1,000 volts, laba baxhumana nabo basebenza ngamakhoyili anikwe amandla yisiginali yokulawula futhi asetshenziselwa kabanziUkuqalwa kwezimoto,Ukushintsha kweCapacitor, eUkulawulwa kweTransformer.
Izinkambu zohlelo lokusebenza ze-Voltage Voltage Thontana nazo
Abantu abaxhumana nabo bathola indima yabo engxenyeni ethile yezimboni laphoUkushintshwa okuthembekile, okusheshayo, nokuphindaphindaiyadingeka:
- Imishini yezimboni esindayo(amalambu ensimbi, imishini yezimayini, ukugaya amamitha)
- Izikhungo Zokulawula Izimoto (MCCs)Kwi-automation kanye nenqubo yokulawula
- Ukushintsha kwebhange leCapacitorEzinhlelweni zokulungiswa kwe-Power Factor
- Izinhlelo Zokuphonswa KwezitimelaeIzinto zeMetro
- Izinhlelo zamandla avuselelekayo, ikakhulukazi kwabakwa-inverters kanye nabaguquli
Izitayela Zemakethe Nezimboni Zomhlaba
Isidingo sembulunga yonkeAmadivayisi ashintshile asebenza kahleKukhulise ukwamukelwa kwabaphakathi kwabaxhumana nabo engxenyeni ephansi yevota. Izimanjemanje, umakethe oxhumana naye kubhekiselwe ukufinyelela$ 1.5 billion ngo-2026, ngemiklamo esekwe kwi-vacuum ithola isabelo semakethe ngenxa yazoubungane bezemveloeisikhathi sokuphila esishelelekile.
Ieee amanothi emibikweni yawo ngezinhlelo zokuxhumana kagesi ezithi bavukela iziphazamisoIzakhiwo eziphakeme ze-dielectric, ukunika amandla ukuhlanza ukushintshana ngisho nasemaceleni aphezulu ane-arcing encane. Imisebenzi Ebucayi Ebucayinjengezibhedlela, izikhungo zedatha, kanye nemigqa yokukhiqiza.

Ungayikhetha kanjani i-Voltage Voltage Voltage Volcuum Contactor
Ukukhetha oxhumana naye ofanele kubandakanya ukulinganisa izinto ezimbalwa ezibalulekile:
- I-voltage ekalwe futhi yamanje: Qondanisa imininingwane yemoto yakho noma yomjikelezo.
- Umjikelezo Womsebenzi: Khetha amamodeli aphezulu ebangeni lokushintsha njalo noma ngokuhamba ngebhayisikile.
- Isikhathi sokuphila se-Mechanical: Qinisekisa inani lemijikelezo esekelwa isicelo sakho.
- Lawula ukuhambisana kwe-voltage: Qinisekisa ukuthi i-Coil Voltage ifana ne-PLC yakho noma umthombo wokulawula.
- Ukuqinisekiswa: Bheka i-IEC 60947 noma i-ANSI yokuhambisana nokuhambisana kwamanye amazwe.
Ithiphu:Uma uhlelo lwakho lokusebenza lubandakanyaUkushintshwa kwe-capacitive, njengasebhange laseCapacitor, qinisekisa ukuthi oxhumana nabo ulinganiselweinrush yamanje ukuphatha.
Izinzuzo ze-Voltage Voltage Volcuum Oxhumana Nabasebenzi
- Ukuphila Okuhlukile: Ukuphila Ngemishini> Ukusebenza kwezigidi eziyi-1
- Ukusebenza kwamahhala: AKUKHO MLASI OKUSHINTSHA OKUSUKA
- Hlanza ukucindezelwa kwe-arc: Kuphephile futhi kuthule kunabaxhumana nabo emoyeni
- Ukusetshenziswa kwamandla okuphansi: Idizayini esebenza kahle yekhoyili inciphisa ukwakha ukushisa
- Usayizi ohlangene: Kufanelana kuma-MCC akhona namaphaneli aphansi aphansi
Imithombo Egunyaziwe kanye Nokugunyazwa Kwezimboni
Imininingwane kule ndatshana Ibhekisela izinhlangano eziningi ezigunyaziwe ukuqinisa ukuthembeka nokucoca kahle:
