Muyezo Watsopano wa Chitetezo cha RCCB Wakhazikitsidwa, Kupititsa patsogolo Chitetezo cha Chitetezo cha Magetsi

Lofalitsidwa pa: Novembala 21, 2025 Wolemba: Wendy Gwero: www.elecogroup.com

Posachedwapa, gawo la chitetezo chamagetsi ku China lasinthidwa kwambiri ndi kope latsopano la "Safety Technical Specification for Residual Current Operated" Chotsegula Deras(RCCB)"ikuyamba kugwira ntchito mwalamulo.".Izi zikuyimira gawo latsopano la "chitetezo cholondola komanso kusintha mwanzeru" kwa ma RCCB (Residual Current Operated Circuit Breakers, omwe amadziwikanso kuti ma RCCB breakers), zida zodzitetezera zofunika kwambiri pachitetezo chamagetsi. Ogwiritsa ntchito ambiri angadzifunse kuti, "Kodi RCCB ndi chiyani?" Mwachidule, ndi chipangizo chodzitetezera chomwe chimazindikira kutuluka kwa madzi ndikugubuduka mwachangu. Chimakwaniritsa ntchito za ma MCB (Chotsegula Dera Chaching'onos), zomwe zimayang'ana kwambiri pa kuteteza kupitirira muyeso, pomwe ma RCBO (Residual Current Operated Circuit Breakers with Overload Protection) ndi zinthu zophatikizika zomwe zimagwirizanitsa ntchito za ma RCCB ndi ma MCB. Akatswiri amakampani amanena kuti kukweza kumeneku kudzayendetsa kusinthasintha kwa zinthu m'makampani onse ndikuchepetsa chiopsezo cha ngozi zachitetezo zomwe zimachitika chifukwa cha kutayikira kwa magetsi.

Malinga ndi deta yochokera ku China Electrical Equipment Industry Association, kutayikira kwa magetsi kumayambitsa moto woopsa wa 30% ku China chaka chilichonse. Kumbuyo kwa ziwerengerozi, kulephera kukhazikitsa ma RCCB ovomerezeka kapena kugwiritsa ntchito zinthu zakale ndi chinthu chofunikira kwambiri chomwe chimayambitsa izi.Kutengera mtundu woyambirira, muyezo watsopanowu umakonza zizindikiro zitatu zazikulu: choyamba, umafupikitsa nthawi yogwirira ntchito kuchokera pa masekondi 0.2 mpaka masekondi 0.1, zomwe zimathandizira kwambiri chitetezo ku kugundana kwa magetsi. Izi zikuwonekera bwino kwambiri mu RCCB 30mA specification yomwe imagwiritsidwa ntchito kwambiri m'nyumba zogona, komwe kulondola kwa chitetezo kwakulitsidwa kwambiri; chachiwiri, umakulitsa kuchuluka kwa magetsi oyenera kufika pa 110V-400V, komwe kumagwirizana ndi zosowa zamagetsi zapakhomo ndi zapadziko lonse lapansi m'njira zosiyanasiyana; chachitatu, umawonjezera zofunikira pa ntchito zanzeru zozindikira zolakwika, zomwe zingapereke ndemanga zenizeni pa momwe zida zimagwirira ntchito ndikuthandizira kuyang'anira ndi kukonza nthawi zonse pogwiritsa ntchito choyesera cha RCCB.

"Kukhazikitsidwa kwa muyezo watsopano kwathetsa mavuto a chitetezo cha ma RCCB achikhalidwe m'mavuto ovuta amagetsi," adatero Pulofesa Li, mainjiniya wamkulu ku bungwe lofufuza za chitetezo chamagetsi. "Tengani zitsanzo za magalimoto atsopano ochapira magetsi: zinthu zakale zinkagwa chifukwa cha kusinthasintha kwamakono, pomwe ma RCCB omwe akutsatira muyezo watsopano amatha kuzindikira molondola mafunde olakwika ndi kusinthasintha kwabwinobwino kudzera mu ma algorithms anzeru, ndikuwonjezera kulondola kwa chitetezo ndi kupitirira 60%.

Atolankhani adaphunzira kuchokera ku makampani ambiri amagetsi kuti makampani otsogola amaliza kafukufuku ndi chitukuko komanso kupanga ma RCCB atsopano ambiri, omwe pang'onopang'ono ayamba kugulitsidwa pamsika. Mneneri wa kampani yotsogola yopanga magetsi adawonetsa kuti ma RCCB awo atsopano amachita zinthu zoposa kungotsatira zomwe zasinthidwa. Mwa kuphatikiza magwiridwe antchito a IoT, amapatsa ogwiritsa ntchito mphamvu zowunikira momwe zinthu zilili komanso zidziwitso za zolakwika kudzera pa pulogalamu yam'manja.Kuchuluka kwa oda ya malonda kunapitirira mayunitsi 500,000 mwezi woyamba pambuyo poti yatulutsidwa.

Ndikofunika kudziwa kuti muyezo watsopanowu umafotokozeranso zofunikira pakupanga ma RCCB. Umanenanso kuti zochitika zosiyanasiyana, monga nyumba zogona, nyumba zamalonda, ndi malo ogwirira ntchito zamafakitale, ziyenera kukhala ndi ma RCCB amitundu yofanana. Mwachitsanzo, RCCB 30mA ndiyofunikira pakugwiritsa ntchito nyumba, pomwe zinthu zapamwamba zimafunika pazochitika zamafakitale. Pakukhazikitsa, chizindikiro cha RCCB (chizindikiro chokhazikika) pa chinthucho chiyenera kutsimikiziridwa, ndipo kuyambika ndi kuyesa kuyenera kumalizidwa ndi akatswiri amagetsi pogwiritsa ntchito choyezera cha RCCB. Akuluakulu oyang'anira msika m'madera osiyanasiyana ayambitsa kuwunika kwapadera nthawi imodzi, kuyang'ana kwambiri pakufufuza zinthu zosakhazikika zomwe zikulowa pamsika ndi mavuto olakwika pakukhazikitsa, komanso kuyang'anira kusankha ndi kufananiza bwino zinthu za RCCB ndi RCBO.

 Akatswiri amakampani akuyembekeza kuti kukhazikitsidwa kwathunthu kwa muyezo watsopano kudzalimbikitsa kusintha kwa msika, zomwe zidzakometsera makampani omwe ali ndi luso la R&D lamphamvu. Nthawi yomweyo, chidziwitso chowonjezeka cha anthu chokhudza chitetezo chamagetsi m'nyumba chikuyembekezeka kukulitsa kufunikira kwakukulu kwa nyumba zomwe zilipo kale.Zikuyembekezeka kuti kukula kwa msika wa RCCB ku China kudzapitirira ma yuan 8 biliyoni mu 2026, ndi kukula kwa chaka ndi chaka kwa 15%.

Pofuna kuthandiza ogula ndi mabizinesi kusankha molondola zinthu zomwe zikugwirizana ndi muyezo watsopano, mabungwe oyenerera atulutsa "RCCB Product Selection Guide," yomwe imafotokoza momveka bwino kusiyana kwa kusankha pakati pa RCCB ndi RCSE Muzochitika zosiyanasiyana, kuchuluka kwa momwe zinthu zodziwika bwino monga RCCB 30mA zimagwiritsidwira ntchito, komanso njira yodziwira chizindikiro cha RCCB. Ogwiritsa ntchito amatha kuwona mndandanda wazinthu zovomerezeka patsamba lovomerezeka la bungwe kapena nsanja zokhazikika zamalonda apaintaneti. Ndikofunikiranso kugwiritsa ntchito nthawi zonse choyezera cha RCCB kuti muwone momwe zida zimagwirira ntchito ndikuwonetsetsa kuti chitetezo chikugwira ntchito bwino.
