Kufunika kwa chitetezo champhamvu pakupanga mphamvu ya photovoltaic

Monga chipangizo china chilichonse chamagetsi, ma solar arrays amatha kupanga ma voltages omwe amatha kuwononga zida ndi kuimitsa chipangizocho.chipangizo chachitetezo cha surgekuthandizira kuti dongosolo liziyenda.

Ganizirani za kompyuta yapanyumba kapena yakuofesi.Kuphatikiza pa ma desktops kapena laputopu, patha kukhala oyang'anira akunja, olankhula kapena osindikiza.Zida zambiri sizinathe kulumikiza pakhoma, kotero anthu ambiri adagula bolodi.Komabe, gulu si njira yabwino yomatira mulu wa zinthu mu socket.Zimathandizira kuteteza zamagetsi izi ku zotsatira zoyipa za ma surges.

Kuthamanga, komwe kumadziwikanso kuti magetsi osakhalitsa, nthawi zambiri kumatanthauza kuwonjezereka kwamagetsi kwakanthawi komwe kumakhala kokwera kwambiri kuposa nthawi zonse.Mwachitsanzo, mphamvu yamagetsi yanyumba kapena ofesi ndi 120V.Voltage imatha kuganiziridwa ngati kuthamanga kwamagetsi.Chifukwa chake, monga momwe madzi amadziwira kwambiri amatha kupangitsa kuti paipi yamunda iphulike, mphamvu yamagetsi yokwera kwambiri imatha kuwononga zamagetsi.Mafundewa amatha kuchokera kuzinthu zachilengedwe, monga mphezi, komanso kuchokera mkati kapena zida zam'mphepete mwa gridi yamagetsi.

Chipangizo choteteza ma surge chimathandizira kuletsa kuwonongeka kwa zida zamagetsi posamutsa mphamvu zochulukirapo kuchokera ku mizere yamagetsi ya "Hot" kupita ku mawaya apansi.M'malo ambiri oteteza maopaleshoni, izi zimatheka ndi metal oxide varistors (MOV) , ​​zomwe ndi ma oxide achitsulo olumikizidwa ku mphamvu ndi mawaya apansi kudzera pa semiconductors ziwiri.

Mphamvu za dzuwa zimafunikira Surge Protector

Ma solar amakhalanso ndi zida zamagetsi, chifukwa chake amakhala ndi zoopsa zomwezo za kuwonongeka kwa opaleshoni.Makanema adzuwa amakhala pachiwopsezo chachikulu cha kugunda kwa mphezi chifukwa cha malo awo akulu komanso malo owonekera, monga padenga kapena malo otseguka pansi.

Opanga ma sola sakudziwa nthawi zonse ngati akumanga m'malo omwe amakonda kugunda mphezi.Phatikizani zambiri kuchokera ku US Lightning Detection Network kukhala chida chaulere chomwe chimalola makontrakitala adzuwa kuti awunikire kuopsa kwa mphezi pamapulojekiti awo.

Mphezi ndi pafupifupi 50,000 ° F (kasanu kuposa Dzuwa) , kotero sizodabwitsa kuti zingakhale zovulaza ku zipangizo za dzuwa.Mukagunda solar panel mwachindunji, mphezi imatha kuwotcha mabowo mu chipangizocho kapena kuyambitsa kuphulika, ndipo dongosolo lonselo lidzawonongedwa.

Komabe, zotsatira za kuyatsa ndi zina overvoltages si nthawi zonse zofunika.Zotsatira zachiwiri za zochitikazi sizidzakhudza zigawo zikuluzikulu zokha monga ma modules ndi inverters, komanso machitidwe owonetsetsa, kuyang'anira ma spotter ndi malo a nyengo, Sirava adati.

Chitetezo champhamvu

Zotsatira zachiwiri nthawi zambiri zimakhala zoopsa zomwe sizidziwika.Kutayika kwa gawo la PV kumatanthawuza kutayika kwa chingwe, pamene kutayika kwapakati pa inverter kumatanthawuza kutaya mphamvu m'madera ambiri a zomera.

Kuyika kwa chitetezo chachitetezo

Chifukwa zida zonse zamagetsi zimangokhudzidwa ndi kuphatikizikako, SPD imatha kugwiritsidwa ntchito pazinthu zonse zamagetsi zamagetsi.Mitundu ya mafakitale yazidazi imagwiritsanso ntchito kuphatikiza kwa metal oxide varistors (MOV) ndi zida zina zosakhalitsa kuti zifalitse kuphulika kwa nthaka.Zotsatira zake, SPD nthawi zambiri imayikidwa pambuyo pokhazikitsa maziko otetezedwa.

Kutengera chithunzi chamagetsi chamzere umodzi wa SPD kuchokera pazida zogwiritsidwa ntchito kupita ku zida zotsatsira, zokhala ndi zida zokonzera zolimba pakhomo loyambira, kupewa kuphulika kwakukulu ndi zida zing'onozing'ono zomwe zimafika kumapeto kwa chipangizocho m'njira zovuta.

Ma network a SPD akuyenera kuyikidwa mu AC ndi DC kugawa mumtundu wa solar kuti asunge mabwalo ovuta.Chipangizo cha SPD chidzayikidwa pamagetsi a DC ndi kutuluka kwa AC kwa inverter ya system, ndipo mizere yabwino ndi yolakwika ya DC idzakhazikitsidwa pamene ikhazikika.Kukonza kwa AC kudzayikidwa pa chingwe chilichonse chokhazikika.Mabwalo ophatikizira nawonso azisungidwa, ndipo mabwalo onse owongolera komanso njira zowunikira komanso zowunikira azisungidwa kuti apewe kusokonezeka ndi kutayika kwa data.

Pankhani yamadongosolo abizinesi ndi zofunikira, lamulo la 10m likulimbikitsidwa.Pazida zomwe zili ndi chingwe cha DC kutalika kwa 10m (33ft), chipangizo cha DC solar surge chitetezo chiyenera kukhala pamalo abwino, monga malo a inverter, bokosi la basi kapena pafupi ndi gawo la solar.Pazida zokhala ndi chingwe cha DC kutalika kwa 10m,chipangizo chachitetezo cha solaridzakhazikitsidwa kumapeto kwa inverter ya inverter ndi kumapeto kwa chingwe.

Makina okhala ndi dzuwa okhala ndi ma inverter ang'onoang'ono ali ndi zingwe zazifupi za DC, koma zingwe zazitali za AC.SPD yoyikidwa pazigawo zambiri imatha kuteteza nyumbayo ku zotsatira za kuchuluka kwa kuchuluka.Kuphatikiza pa ma surges ochokera ku mphamvu zamatauni ndi zida zina zamkati, oteteza mawotchi pa boardboard amatetezanso nyumbayo kuti isayambike.

M'makina amtundu uliwonse, SPD idzayendetsedwa ndi akatswiri amagetsi omwe ali ndi zilolezo paupangiri wa wopanga komanso molingana ndi kuyika ndi kuyika muyeso wamagetsi kuti apititse patsogolo chitetezo ndikuchita bwino.

Njira zina zitha kutsatiridwa, monga kuwonjezera ndodo zamphezi kuti zipititse patsogolo mapanelo adzuwa kuti asawale.

Ngakhale dongosolo lamphamvu kwambiri lokonza mawotchiwa lili ndi malire ake.Mwachitsanzo, a SPD sangapewe kuwonongeka kwakuthupi komwe kumachitika chifukwa chakugunda kwamphezi.

Izi ndi zomwe sayansi yamakono ingachite:chipangizo chachitetezo cha surge
