Khoom taw qhia:

Thaum T-txuas txuas kab ntawm 12kV nyiaj siv ua haujlwm faib kab lossis kev ua txhaum sab hauv ntawm tus neeg siv kawg tshwm sim, qhov kev hloov pauv ntawm lub substation yuav raug tripped thaum lub sij hawm tiv thaiv kev txwv ntawm cov kab nkag mus thiab lub sij hawm tiv thaiv ntawm cov kab tawm ntawm lub substation tsis tuaj yeem hloov kho kom tsim nyog. Yog hais tias qhov kev ua txhaum yog nyob mus ib txhis, lub substation reclosing yuav tsis muaj kev vam meej, thiab lub zos xwm txheej nyob rau hauv lub nruab nrab voltage tus neeg siv ciam teb yuav ua rau tag nrho cov 12kV tis kab poob hwj chim. Yog hais tias ib tug sab nraum zoov demarcation Circuit Court breaker yog ntsia nyob rau hauv lub T hlws ris los yog ntawm tus neeg siv kawg (lub luag hauj lwm demarcation point), nws yog txiav txim siab hais tias ib tug txhaum (overcurrent, luv luv Circuit Court, ib-theem grounding, thiab lwm yam) tshwm sim nyob rau hauv tus neeg siv ciam teb, thiab qhov txhaum yog txiav tawm. Cov neeg siv nyob rau hauv qhov chaw tsis muaj teeb meem siv hluav taws xob ib txwm muaj. Daim ntawv thov ntawm ZW32-12F sab nraum zoov high-voltage intelligent demarcation nqus Circuit Court breaker (watchdog) ntawm 12kV feeder overhead kab tuaj yeem zam qhov kev sib koom ua ke ntawm lub zog tsis ua haujlwm ntawm txoj kab tsis raug, txo qhov cuam tshuam ntawm qhov txhaum hluav taws xob, txo tus neeg siv lub sijhawm hluav taws xob, thiab tiv thaiv kev nyab xeeb ntawm lub network tseem ceeb. Thiab nws muaj kev ua haujlwm ntawm kev kuaj xyuas qhov txhaum, kev tiv thaiv kev tiv thaiv thiab kev sib txuas lus, uas tuaj yeem paub qhov tsis siv neeg tshem tawm ntawm ib theem hauv av txhaum thiab tsis siv neeg rho tawm ntawm theem-rau-theem luv-circuit txhaum. Lub installation taw tes yog siv nyob rau hauv lub luag hauj lwm demarcation point ntawm tus neeg siv cov khoom nkag ntawm 12kV tis kab, thiab nws kuj yuav siv tau rau cov ceg kab kev twb kev txuas uas ua tau raws li qhov yuav tsum tau.

Tej yam kev mob ntawm kev siv:
ambient kub: tsis siab tshaj +40ºC, tsis qis dua -15ºC;
Huab cua txheeb ze av noo: qhov nruab nrab txhua hnub tsis ntau tshaj 95%, thiab qhov nruab nrab txhua hli tsis tshaj 90%;
Qhov siab tsis tshaj 1000 meters;
Av qeeg siv tsis tshaj 8;
Ib qho chaw tsis muaj hluav taws kub, tawg, muaj kuab paug loj, tshuaj lom neeg corrosion thiab kev co hnyav.
