Mumashandisirwo emagetsi emazuva ano uye zvishandiso zvemagetsi, ma-surge protectors (SPDs) nema-inverter, sezvikamu zviviri zvakakosha, kushanda pamwe chete kwavo kwakakosha pakuona kushanda kwakachengeteka uye kwakasimba kwehurongwa hwese. Nekukura nekukurumidza kwesimba rinogona kuvandudzwa uye kushandiswa kwakapararira kwemidziyo yemagetsi yemagetsi, kushandiswa pamwe chete kweizvi zviviri kwave kwakajairika. Chinyorwa chino chichaongorora misimboti yekushanda, zvinodiwa pakusarudza, nzira dzekuisa maSPD nema-inverter, pamwe nekuti angabatanidzwa sei zvakanaka kuti ape dziviriro yakakwana kumasisitimu emagetsi.

Mumagetsi emazuva ano, mudziyo wekudzivirira we surge (SPDs) une basa rakakosha. Ingava mudzimba, mafekitori, nzvimbo dzedata kana nzvimbo dzekutaurirana, maSPD anogona kudzivirira zvinobudirira kubva kumagetsi anodarika mwero anokonzerwa nekurova kwemheni, kushanduka kwegridi yemagetsi nezvimwe zvinhu, zvichiita kuti michina ishande zvakachengeteka. Chinyorwa chino chichatsanangura tsananguro, musimboti wekushanda, nzira yekusarudza uye gwara rekuisa maSPD zvakadzama, uye tichakurukura kukosha kwawo nezviitiko zvinoshanda. Pamusoro pezvo, tichaongororawo migumisiro yakakomba inogona kuitika kana pasina SPD.

Muna 2024, kurasikirwa kwakananga kwehupfumi kwakakonzerwa nekurohwa nemheni pasi rose kwakasvika mabhiriyoni mana nemazana manomwe emadhora ekuAmerica, neinenge 60% yekurasikirwa uku kwakakonzerwa nekudzivirirwa kusina kukwana kwemasisitimu emagetsi. Semudziyo unokosha wekudzivirira kukwira kwemagetsi, mhando yekuiswa kwemidziyo yekudzivirira kukwira kwemagetsi (SPDs) inosarudza zvakananga kuvimbika kwesisitimu yese yemagetsi. Chinyorwa chino chichaongorora zvakavanzika zvekuiswa kweiyi "power guardian", ichikutungamira kuburikidza nemhinduro yakazara kubva pamisimboti kusvika pakushandiswa kunoshanda.

Kugona kwemagetsi ezuva pasi rose kwakaiswa pamagetsi kwakapfuura 350GW gore rapera, China ichipa mari inodarika chikamu chimwe muzvitatu. Iyi tekinoroji yegirini inoshandura chiedza chezuva kuita magetsi yakaona mitengo yayo ichiderera ne80% mumakore gumi, asi inotarisana nenjodzi inouraya yekurohwa nemheni - nzvimbo yemagetsi muArizona, United States, yakamborasikirwa nemamiriyoni maviri emadhora nekuda kwekurohwa nemheni. Zvidziviriro zvemagetsi zvave "chinhu chinoponesa hupenyu" chezviteshi zvemagetsi, zvichitungamira makumi ezviuru zvevolts zvemagetsi emheni pasi kuburikidza nenetwork yekudzivirira ine nhanho nhatu. Nyanzvi dzeindasitiri dzakataura kuti sezvo voltage yemagetsi emagetsi ezuva ichikwira kusvika ku1500V, michina yekudzivirira iri kutanga shanduko yetekinoroji muzvinhu zvesilicon carbide.

Kubva pakuiswa kusvika pakugadzirisa, ruzivo urwu harufanirwe kufuratirwa

Mumagetsi emazuva ano, ma "surge protectors" (SPD) akafanana ne "inshuwarisi" yemidziyo yemagetsi. Asi waizviziva here? Mudziyo uyu unoita seuri nyore, kana ukaiswa kana kushandiswa zvisina kunaka, haungogumiri pakudzivirira chete asi unogona kutokonzera njodzi yekuchengetedzeka. Nhasi, ngatitaurei nezvezvinhu zvinokuvadza pakushandisa maSPD.

Sezvo simba remagetsi ezuva nezuva rakaiswa pa photovoltaic richidarika chiratidzo che1TW, kuvimbika kwesystem uye nyaya dzekuchengetedza zviri kuramba zvichiwedzera kuoneka. Zvichienderana nenhamba dzichangoburwa kubva kuInternational Electrotechnical Commission (IEC) TC82 Technical Committee, kutadza kushanda zvakanaka kwemagetsi ndiko kunokonzera kusvika 41.3% yekukundikana kushanda nekugadzirisa kwezviteshi zvemagetsi ezuva nezuva, izvo kukuvara kwemidziyo kunokonzerwa nekupfuura simba remagetsi kwenguva pfupi kunokonzera 28.7% yekukundikana kwese. Chiitiko ichi chakakosha zvikuru munzvimbo dzinopisa uye dziri pasi pemvura dzine dutu rakawanda.

Nekukura kuri kuita indasitiri yepasi rose yemagetsi ezuva, kuchengetedzeka nekugadzikana kwemagetsi ezuva kwave chinhu chinonyanya kutariswa neindasitiri. Mamagetsi ezuva anoonekwa panze kwenguva yakareba uye anogona kutyisidzirwa nemheni, kushanduka kwegridi yemagetsi, uye kutadza kwemidziyo, izvo zvinogona kukonzera kukuvara kwemidziyo kana kutopisa. Madhiraivha emagetsi (SPDs), macircuit breakers, uye mafuse zvishandiso zvakakosha zvekudzivirira izvo chimwe nechimwe chinoita mabasa acho uye chinoshanda pamwe chete kuti chive nechokwadi chekushanda kwakachengeteka kwemagetsi. Chinyorwa chino chichaongorora zvakadzama mabasa avo, nzira dzekubatanidza, uye kukosha kwekupa ruzivo kune vashandisi veindasitiri.

Sei Midziyo Yako Ichida "Voltage Bodyguard"?

Fungidzira izvi: Pausiku hune dutu nemheni ichiyerera mudenga, michina yako yemagetsi inokosha mazana ezviuru inongoerekana "yatanga kurohwa." Iyi haisi nyaya yemufirimu unotyisa asi ihope chaiyo yakasangana nemafekitori mazhinji nemhuri. Mudziyo wekudzivirira mafungu (SPD) ndiwo "gamba guru" renyaya iyi—unokwanisa kudzivirira ma voltage spikes ane njodzi muchikamu chemamiriyoni chesekondi. Asi heino dambudziko: vanhu vazhinji vanounza "bodyguard" uyu kumba vasingazive mashandisirwo ake nemazvo.

Nhasi, ngatitaurei nezvemuchengeti uyu wekuchengetedza magetsi unoratidzika kunge uri nyore asi wakaoma kunzwisisa.

Munyika yanhasi inotungamirwa netekinoroji, michina yemagetsi neyemagetsi iri panjodzi huru yekukuvadzwa nemagetsi anokonzerwa nekurova kwemheni, kushanduka kwegrid, kana mashandiro ekuchinja kwemukati. Zvidziviriro zvemafungu, zvinozivikanwawo semidziyo yekudzivirira mafungu (SPDs), zvinoita basa rakakosha mukudzivirira michina inobatwa nemagetsi kubva pakukwira kwemagetsi. Chinyorwa chino chinoongorora mashandisirwo anoshanda ezvidziviriro zvemafungu muindasitiri dzakasiyana uye chinoratidza kushanda kwazvo kuburikidza nezvidzidzo zvezviitiko.

Nhanganyaya

Zvidziviriro zveSurge (SPDs) zvinhu zvakakosha mumagetsi ekuderedza overvoltages dzinopfuura uye shunting surge currents. Zvinoshandiswa zvakanyanya mumagetsi akananga (DC) uye alternating current (AC). Nekuda kwehunhu hwakasiyana hwezvidziviriro zveDC surge uye zvidziviriro zveAC surge, zvidziviriro zvavo zveSurge zvakasiyanawo zvakanyanya muchimiro, musimboti wekushanda, uye mamiriro ekushandiswa. Chinyorwa chino chichaongorora kufanana uye musiyano uripo pakati pezvidziviriro zveDC surge neAC surge protectors zvakadzama, uye kupa mazano ekusarudza.
