1. Cov lus piav qhia dav dav
BHA series Load Break Switch, suav nrog cov pov thawj tiaj tus-chamber arcing thev naus laus zis, tuaj yeem ua tau ntau yam kev hloov pauv hauv nruab nrab-voltage distribution systems. Lawv yog cov txiaj ntsig ntawm ntau tshaj 50 xyoo kev paub hauv kev txhim kho thiab tsim khoom ntawm kev hloov pauv los ntawm SHONEVAC. Qhov yooj yim, qis-kev tu thiab kev lag luam hauv tsev loj heev hauv kev hloov pauv hauv BHA series muaj cov ntaub ntawv pov thawj kev pabcuam, nrog ntau pua txhiab units tau nruab thiab ua haujlwm ntawm ntau lub tshuab.
BHA load break hloov ua raws li cov cai ntawm IEC 60694 (EN 60694) thiab IEC 60265-1 (EN 60265-1). Tsis tas li ntawd, cov kev xaiv xaiv muaj, ua raws li IEC 62271-105 (EN 62271-105).
2. Cov ntawv thov tseem ceeb
BHA series load so switc yog tsim los siv rau hauv nruab nrab sab hauv tsev - voltage switchgear systems. Lawv muaj peev xwm ua tau thiab tsim nyog rau kev hloov pauv:
- load tam sim no
- tam sim no nyob rau hauv lub nplhaib mains
- transformers, cables thiab overhead kab.
BHA load break hloov yog qhov txhim khu kev qha thiab nyiaj txiag kev daws teeb meem rau kev kho dua tshiab thiab kho cov kev pab cuam, txuas ntxiv, rov ua dua tshiab lossis hloov kho cov neeg ua haujlwm tiv thaiv.
3. Cov yam ntxwv tshwj xeeb
- kev ntseeg siab thiab kev pab lub neej ntev
- tus nqi khiav lag luam qis vim yog lub sijhawm ntev ntawm cov txheej txheem txij nkawm
- space-txuag tsim
- muaj peev xwm hloov tau siab
- qis ua haujlwm torque
- haum rau siv nyob rau hauv hnyav climatic tej yam kev mob
- zoo tagnrho raws li kev hloov rau cov laus load break hloov
- load break hloov- fuse ua ke rau IEC 62271-105 (EN 62271-105) muaj.

5. Siv tau ib puag ncig
Qhov hloov pauv yog siv rau peb - kab AC 50Hz Circuit Court, rau kev siv hluav taws xob thiab tsis muaj kev thauj khoom thaum lub voj voog.Cov kev siv yooj yim yog raws li hauv qab no:
- ambient kub: -25C ~ +40 degree;
- Qhov siab: Tsawg dua lossis sib npaug li 1000m;
- Tus txheeb ze av noo: nruab nrab txhua hnub Tsawg dua lossis sib npaug li 95%, qhov nruab nrab txhua hli Tsawg dua lossis sib npaug li 90%;
- Av qeeg siv: Tsawg dua lossis sib npaug li 8 qib;
- Cov chaw teeb tsa: tsis muaj hluav taws kub, tawg phom sij, ua qias neeg, tshuaj lom neeg corrosion lossis kev co hnyav.

7 Kev thauj mus los thiab khaws cia
Kev thauj mus los ntawm kev hloov pauv yuav tsum tau ua los ntawm txhua hom kev thauj mus los raws li Txoj Cai rau Kev Thauj Khoom hauv kev quab yuam rau txhua hom kev thauj khoom. Kev thauj mus los ntawm cov khoom ntim khoom ntim yuav tsum tsis suav nrog qhov muaj peev xwm raug cuam tshuam ncaj qha rau huab cua nag lossis daus thiab ib puag ncig hnyav.
8 TXOJ CAI
Cov keyboards yog ua los ntawm cov hlau thiab cov plooj (porcelain) thiab tsis muaj cov khoom uas tuaj yeem ua rau kev noj qab haus huv thiab ib puag ncig. Cov kev hloov tom qab kawg ntawm lawv lub neej kev pab cuam yuav raug hloov mus rau cov koom haum ua haujlwm ferrous thiab tsis yog -ferrous hlau. Yog tias lub ntim tsis xav tau lawm, nws tuaj yeem rov ua dua tshiab.
9 QHOV CHAW UA HAUJ LWM
