Nzira yekusarudza sei chidziviriro chekudzivirira (SPD)?
Surge Protective Devices (SPD) inoshandiswa kudzivirira midziyo yemagetsi pamusoro pemakumbo (kuputika) kunokonzerwa nemheni kana kuchinja kwemashini emitoro yakaoma (vanhu vakawanda vangasazvidza izvi). Zvinogona kutora humwe hutano hunoshandiswa paunosarudza chikwata chekudzivirira chakakodzera sezvo pane mitambo yakasiyana-siyana nemitemo.
IEC inonzi IEC 61643 inotsanangura 3 mhando dzezvidziviriro zvekuchengetedza zvigadziriswa zvepasi rekutsika kwemagetsi.
Tora 1 kana Chikamu I: Tora 1 SPD inogona kubudisa simba guru remheni uye rinoshandiswa mumagetsi ekugadzira switchboard iyo chivako ichichengetedzwa nemheni inodzivirira system (mheni inopenya, pasi padziviriri uye pasi).
Tora 2 kana Chikamu II: Izvi zvinodzivirira chipambo (SPD) yakagadzirirwa kubudisa ikozvino yakagadzirwa nechisina kumira mhepo yakagadzikana iyo yakakonzera kudengenyeka pamagetsi ekuparadzanisa. Kazhinji, ivo vanoiswa panzvimbo huru yekuparadzira switchboard. Tora 2 SPD Ndiyo SPD inonyanya kuzivikanwa pamusika uye Prosurge iri kuvapa zvivako zvakasiyana.
Tora 3 kana Chikamu III: Type 3 SPDs yakagadzirirwa kuderedza kuwedzerwa pamagetsi ezvinhu zvinoshandisa uye saka ine hama shoma yakasununguka ikozvino.

Chirongwa 1 SPD chinoita zviri nani kupfuura Chirongwa 2 SPD?
Kwete hazvo. A Type 1 SPD inopa kushandiswa kwehutano kuburikidza nekukwanisa kushamwaridzana kune rumwe rutivi rwemukova webasa, asi UL hairi kuenzanisa kubuda kwechigadziro chekuita kweChirudzi 1 SPD kana cheChiratidzo 2 SPD. UL inoongorora kusungirirwa kwekuita kweSDS dzose zvakaenzana, pasina hanya neDP type. UL inoongororawo SPDs yese yekuchengetedzwa kwakachengeteka mukati mekuda kwekuisa nzvimbo. Kutanga na UL 1449 3rd Rudziro, Rudzi rwe 1 rwakagamuchirwa SPDs ruchabatanidza zvigadzirwa zvaimbozivikanwa seSekondari Surge Arresters uye zvichabatanidzawo mafaira akawanda aimbozivikanwa seTVSS. Zvakakosha kunzwisisa kuti vazhinji veSekondari Arresters type madivayiri zvakagadzirwa nepamusoro MCOV (Maximum Continuous Operating Voltage) kupfuura yaive maTV. Uye sezvo chikwata cheMCOV cheSDD chinogona kuchinja zvakananga pakugadzirisa kushanda, chimiro chakanaka chekusarudzwa kweSDD kunofanira kusanganisira kunyatsofungisisa kwezvikwereti zvakadai sekuwedzera kwemazuva ano, IEEE clamping voltage, UL VPR, uye mararamiro ehupenyu hwekuwedzera.
Ndekupi Ndingaisa SPDs Kuchengetedza Zvangu?
Hazvibviri kudzivirira kuputika kwemhepo kubva pakunopinda munzvimbo yako kana kuti kuitika mukati memunzvimbo yako. Kana dzichidzivirira chivako chinopesana nedzimwe nzira, nzira yakanakisisa ndeyokutengesa kana kusvibiswa. Sezvinoratidzwa mumifananidzo iri pasi apa, Institute of Electrical and Electronics Engineers (IEEE) yakagadzira matatu matatu iyo nzvimbo yose inogona kugoverwa, nzvimbo yeAka A, B uye C. Ona IEEE Standard C62.41.1 neC62.41.2 kuti iwedzere kureva.
Chikamu A: zvivako / zvipfeko uye mativi eguru refu (mukati) (zvisinganyanyisi)
• Zvivako zvose pane zvakawanda izvo 10m (30 ft) kubva muchikamu B
• Zvivako zvose pane zvinopfuura 20m (60 ft) kubva muchikamu C
Chikamu B: feeders, mashomanana mapfupi ebazi uye mapepa ekufambisa (mukati)
• Kuparadzanisa mapaneji emichina
• Bhasi uye kugoverwa kwehuwandu
• Zvinyorwa zvinoshandiswa zvakasimba ne "short" connections kumusuo webasa
• Zviratidzo zvekuvhenekera muzvivako zvikuru
Chikamu C: mitsetse yepamusoro yepamusoro uye gonhi rebasa (kunze)
• Basa rinodonha kubva padanda kusvika pakuvaka
• Inomhanya pakati pemamita nejeri
• Musoro wepamusoro unodzivisa kuvaka
• Migwagwa yepasi pasi kusvika pamapepa akanaka

Ko mheni inogona kuparadza photovoltaic system here?
Photovoltaic systems ine teknolojia yakaoma zvikuru uye mhepo inopenya yemheni inogona kuiparadza zvachose. Pane imwezve njodzi, sezvo kuve kwemheni kunokonzera kubuda kwemhepo pedyo nehurumende yezuva uye izvi zvinogona kukanganisa urongwa. Inverter ndiyo nheyo inokosha inoda kudzivirirwa. Kazhinji, inverters ichabatanidza kuvhara-voltage vadziviriri muvanoshandura. Zvisinei, sezvo izvi zvikamu zvinongorayira zviduku zvishoma, unofanirwa kufunga nezvekushandisa maitiro ekuchengetedza mahara (SPD) mumamiriro ega ega.
