Jinsi ya kupima halijoto katika swichi na kwa nini vifaa vya usambazaji wa nguvu vinatumia mifumo ya kipimo cha joto la nyuzi macho

Kazi ya swichi na kabati ya usambazaji, na sababu za kupanda kwa joto la switchgear na kabati ya usambazaji

Kazi ya baraza la mawaziri la usambazaji wa swichi ni kuweka masanduku maalum ya vifaa vya umeme na saketi kwenye vifaa vya nguvu., na kazi yake kuu ni kusambaza nishati ya umeme. Chini ya operesheni ya kawaida ya switchgear, vipengele na nyaya za baraza la mawaziri la usambazaji hazitazalisha uharibifu mkubwa wa joto au kuchoma. Hata hivyo, wakati malfunctions ya mzunguko, kama vile vipengele vya elektroniki vya kupasha joto, joto la ndani la baraza la mawaziri la usambazaji litaongezeka. Joto kubwa litakuwa na athari kubwa kwenye vifaa vya elektroniki ndani ya baraza la mawaziri la usambazaji, na katika kesi kali, itaharibu vifaa vya elektroniki.

Kwa nini baraza la mawaziri la usambazaji linahitaji kupima kupanda kwa joto na umuhimu wa kifaa cha kupima joto katika swichi
Katika uwanja wa vifaa vya baraza la mawaziri la usambazaji wa voltage ya juu na ya chini, kutokana na mahitaji ya mazingira ya kazi ya baraza la mawaziri la usambazaji lililofungwa, mazingira ya kazi ya baraza la mawaziri la usambazaji imefungwa. Pamoja na kuzeeka kwa vipengele mbalimbali vya elektroniki na nyaya, pointi za mawasiliano kati ya vifaa muhimu vya umeme na nyaya zitawaka moto kutokana na upinzani mkubwa wa kuwasiliana unaosababishwa na vumbi, ulegevu, na oxidation, na sehemu za kupokanzwa zisizo za kawaida zitasababisha hatari mbalimbali za usalama. Hata hivyo, kutokana na mahitaji ya kuziba ya baraza la mawaziri la usambazaji lililofungwa, ni vigumu kwa wakaguzi kuchunguza hali ya kazi ya ndani kupitia njia za kawaida za ukaguzi. Aidha, kutokana na ukweli kwamba vifaa vya kawaida vya kupima joto la ndani ni vyombo vya kupimia joto visivyoweza kuguswa na huathiriwa kwa urahisi na mambo mbalimbali ya sumakuumeme au mazingira kama vile joto la juu na la chini ndani ya baraza la mawaziri la usambazaji., kipimo cha joto kisicho sahihi hutokea. Ubaya wa kazi isiyo na utulivu. Kwa hiyo, kipimo sahihi cha joto mtandaoni cha wakati halisi cha kabati za usambazaji zilizofungwa imekuwa shida ya haraka inayohitaji kutatuliwa katika tasnia..

Ufuatiliaji wa mtandaoni na mfumo wa kipimo cha joto kwa swichi ya juu-voltage
As an important electrical equipment for distributing electrical energy, the high-voltage distribution cabinet generates heat at the switch contacts and busbar connections due to aging or excessive contact resistance during long-term operation. This aging and heating process is a long-term and continuous process, some of which may take several months to manifest. Aidha, due to the exposed high voltage inside the cabinet, temperature monitoring of these heating parts cannot be carried out using conventional methods, especially with the large number of unmanned substations being put into use, conventional manual inspection methods are not competent. Due to the inability to detect temperature changes in abnormal situations of the distribution cabinet in a timely manner, hatimaye husababisha kutokea kwa ajali za moto, kusababisha hasara isiyoweza kuepukika. Ufuatiliaji wa uendeshaji wa wakati halisi wa joto la mawasiliano ndani ya baraza la mawaziri la usambazaji na kutoa maoni kwa wakati juu ya habari ya joto ya mawasiliano ni suluhisho la ufanisi kuzuia ajali katika baraza la mawaziri la usambazaji.. Hata hivyo, kutokana na muundo mdogo ndani ya baraza la mawaziri la usambazaji, vipimo vya kawaida vya joto na vipimo vya ukaguzi wa mwongozo haviwezi kufanyika. Kwa hiyo, kufikia ufuatiliaji wa hali ya joto mtandaoni kwa wakati halisi ni njia muhimu ya kuhakikisha utendakazi salama wa kabati za usambazaji wa voltage ya juu..
