Txheej txheem cej luam

ZN73-12 series sab hauv tsev handcart-hom high-voltage nqus Circuit Court breaker yog ib qho hluav taws xob sab hauv tsev nrog peb-theem AC 50Hz thiab ntsuas qhov hluav taws xob ntawm 12kV.Nws tuaj yeem siv rau kev tswj hwm thiab kev tiv thaiv kev lag luam thiab kev lag luam mining, fais fab nroj tsuag, substations, thiab cov chaw hluav taws xob, thiab tsim nyog rau cov chaw ua haujlwm nquag.Cov txheej txheem kev khiav hauj lwm yog kev koom ua ke nrog lub Circuit Court breaker lub cev, thiab tus tsim yuav siv tau raws li ib tug taag installation unit, los yog nws muaj peev xwm yuav nruab nrog ib tug tshwj xeeb propulsion mechanism los tsim ib tug handcart unit.Lub hauv paus tseem ceeb hauv Circuit Court tuaj yeem siv cov khoom sib txuas ntawm cov khoom sib txuas kom paub txog qhov miniaturization, kev ntseeg siab thiab kev saib xyuas-dawb ntawm Circuit Court breaker.

Cov xwm txheej siv li qub

◆ Ambient kub: tsis siab tshaj 40 ℃, tsis qis dua -10 ℃ (cia thiab tsheb thauj mus los ntawm -30 ℃).
◆ Qhov siab: tsis tshaj 1000m.(Yog tias qhov siab yuav tsum tau nce ntxiv, qhov ntsuas qhov ntsuas hluav taws xob yuav raug nce raws li)
◆ Tus txheeb ze av noo: qhov nruab nrab txhua hnub tsis ntau tshaj 95%, qhov nruab nrab txhua hnub ntawm saturated vapor siab yog MPa, thiab qhov nruab nrab txhua hli tsis ntau tshaj 1.8 × 10.
◆ Kev siv av qeeg: tsis pub tshaj 8.
◆ Ib qhov chaw tsis muaj hluav taws kub, tawg, muaj kuab paug loj, tshuaj lom neeg corrosion thiab kev co hnyav.
