1.Cov ntsiab lus

VSM-12 series ruaj khov hlau nplaum-hom sab hauv tsev high voltage nqus Circuit Court breaker yog peb-theem AC 50Hz, ntsuas qhov hluav taws xob ntawm 12kV sab hauv tsev hloov khoom siv. Nruab nrog cov hlau nplaum ruaj khov ntawm peb lub tuam txhab muaj kev tshawb fawb thiab kev tsim kho rau kev lag luam thiab mining lag luam, tsim hluav taws xob thiab cov chaw ua haujlwm substation raws li hluav taws xob tswj thiab kev tiv thaiv lub hom phiaj. Cov khoom lag luam muaj kev ntseeg siab thiab cov yam ntxwv ntawm lub neej ntev, tshwj xeeb tshaj yog siv rau cov chaw uas muaj mob hnyav, xws li kev ua haujlwm tsis tu ncua, rov ua kom luv luv tam sim no.

2.Ib puag ncig tej yam kev mob

◆Ambient kub: -25 ℃ ~ + 40 ℃;

◆Qhov siab: ≤1000m, toj siab hom ≤3000m;

◆Tus txheeb ze av noo: nruab nrab txhua hnub ≤95%, qhov nruab nrab txhua hli ≤90%, saturated vapor siab txhua hnub

nruab nrab ≤2.2 × 10 MPa, qhov nruab nrab txhua hli ≤1.8 × 10MPa. Thaum kub poob sai heev thaum lub sij hawm

lub sij hawm kub kub, nws yuav tshwm sim condensation.

◆Av qeeg siv: ≤8 qib;

◆Qhov chaw uas tsis muaj hluav taws kub, muaj kev phom sij tawg, ua qias neeg, tshuaj lom neeg corrosion, thiab khaus

kev vibration.
