Zipangizo zodzitchinjiriza zogwiritsira ntchito mafakitale

Kugwiritsa ntchito mafakitale kumaphatikizapo zida zosiyanasiyana zomwe zimayenera kutetezedwa ku zotsatira za ma surges. Ndiokwera mtengo kwa eni kampaniyo: mtengowo ukhoza kukhala waukulu kwambiri ndipo kulephera, kapena kusinthanso, kwa zida izi, kungabweretse mavuto akulu azachuma, mwina kuyika kukhalapo kwa kampaniyo pachiwopsezo. Zinthu zazikuluzikulu, malinga ndi momwe mabungwe amagulu antchito amagwirira ntchito, ndiogwira ntchito: amagwiritsa ntchito zida zamagetsi ndipo, kukachitika kuchuluka, miyoyo yawo ikhoza kukhala pachiwopsezo. Zomwe zatchulidwazi, komanso zifukwa zina, zikuyimira zifukwa zazikulu zomwe munthu ayenera kutetezedwa ku ma surges. Ntchitoyi imagwiritsa ntchito chitetezo cham'kati ndi chakunja kuchokera ku mphezi, monga malo othamangitsira mpweya, kutchinjiriza, busbar yotetezera, ma suppressor oyendetsa, onse omwe amatchedwa zida zodzitetezera, SPD. Pali makampani angapo omwe amapanga zida zambiri, komabe sizomwe zili zoyenera kugwiritsa ntchito mafakitale.

Mtima wa zonsezi, monga zimakhalira, umakhala palamulo kapena chofunikira mwalamulo. Poterepa, ndikutetezedwa kwa Mphezi EN 62305, Gawo I mpaka 4. Lembalo limatanthauziranso mitundu ya zotayika, zowopsa, zoteteza mphezi komanso mulingo wa chitetezo cha mphezi. Pali magawo anayi a chitetezo cha mphezi (I kudzera IV) chomwe chimafotokoza magawo a mphezi; milingo yachitetezo ndi ntchito ya chiopsezo. M'ntchito zambiri zamakampani, nyumbayi imagawidwa ngati Gawo I kapena II. Izi zikugwirizana ndi kuchuluka kwa mphezi pano I_Ndondocha (zomwe zikuchitika pakadali pano ndi magawo 10/350 beings) akukhala 200 kA. Chiyerekezo choyenera chikuwonetsa kuti 50% ya I yonse_Ndondocha Pakadali pano amangidwa ndimalo opumira mlengalenga ndipo amaperekedwa munthawi yoyikira. Zotsalira 50% zimagawidwanso chimodzimodzi pakati pazolowetsa (mwachitsanzo pakati pa omwe amalumikizana nawo omwe akulowa mnyumbayo), makamaka ku zingwe za IT ndi kulumikizirana, kupopera kwachitsulo ndi zingwe zamagetsi za LV.

Pazovuta kwambiri, SPD iyenera kumanga pafupifupi 100 kA. Pogawidwa m'magulu amtundu uliwonse, zomwe zilipo pakadali pano zimakhala 25 kA pa chingwe (pogwiritsa ntchito dongosolo la TN-C). Ichi ndichifukwa chake timalimbikitsa kuti omwe amagawa ma LV unit substations (munyumba zoyenerera ngati chitetezo cha LPL I) akhale ndi Chidziwitso chosindikizidwa chosasiyanitsa ndi kudzazidwa kwa gasi. Pokhala mtundu wa SPD 1, zida zimatsimikizira kufanana ndi kutaya kwa mphezi komanso kusintha komwe kumachitika m'mizere yamagetsi yolowera mnyumbayi.

Itha kumanga I_Ndondocha mafunde akulu ngati 50 kA. Zipinda zazing'ono za nyumba iliyonse ziyenera kukhala ndi Chidziwitso, kuphatikiza kwa SPD Type 1 ndi 2, yomwe imakhala ndi ma varistor apawiri otetezeka kwambiri ndipo imapereka 25 kA yazomwe zingagwire pano. Makabati achiwiri ndi makabati owongolera amayenera kukhala ndi mtundu wa SPD 2. Chitsanzo cha kalasiyo pazomwe timagulitsa ndi Zamgululi, yomwe imaperekedwa ngati gawo lathunthu, losindikizidwa kapena lokhala ndi ma module osinthika.

Ngati chida chotetezedwacho chili mkati mwa 5 m kuchokera ku substation yachiwiri kapena kabati yoyang'anira, dongosololi liyenera kukhala ndi zida za SPD Type 3, mwachitsanzo, TLP10. Ndi fyuluta yapafupipafupi yokhala ndi zotseketsa min. 30 dB mu frequency band 0.15 - 30 MHz yomwe imakhalanso ndi zida zotetezera - ma varistor omwe amapangidwira mafunde oyerekeza kuyambira 16 mpaka 400 A. Zikatero, kuponderezedwa kopatukana kwa LC63 kuyenera kuyikidwa pakati pa SPD Type 2 ndi 3 kuti ipereke kulumikizana kolondola za omanga. Zingwe zotetezedwa zimayenera kuperekedwa pakati pa sitoloyo ndi zida zotetezedwa kuti igwire bwino ntchito.

LSP imaperekanso chitetezo pazochitika zomwe denga la nyumbayo limanyamula ma photovoltaic. Upangiri wathu ndi Kufotokozera: SLP40-PV mndandanda womwe umakwera pamaso pa inverter ndi mkati mwake uli ndi zida zolumikizira zomwe zimayikidwa zikalephera (kutentha) kwa ma varistor ndikuyimitsidwa kwamakina, komwe kumayikidwa pakati pama elektroni osadulidwa kuti akonzekere bwino kupha DC arc. Kutetezedwa kwazomwe mukusintha pakadali pano ndikofunikira, chisankho chabwino ndi Mndandanda wa FLP7-PV.

Tikukulimbikitsani kuti omanga amtunduwu akhazikitsidwe muzipinda monga maholo amaseva, zipinda zoyang'anira, ndi maofesi. Tele-Defender-RJ11-TELE poteteza zida zamafoni, Net-Defender-RJ45-E100 poteteza kufalitsa kwa ma data ndi zidziwitso, NKHANI-BNC-FM poteteza zida zomwe zimafalitsa kanema, Wotetezedwa-ND-CAT-6AEA adapangidwa kuti azigwiritsa ntchito makompyuta asanalowe mu kirediti kadi ndipo adapangidwa kuti aziteteza ndi kufalitsa deta mumanetiwe a Generation 5, ndi Kufotokozera: RJ45S-E100-24U kuyika kwa ogulitsa 19-inchi pa seva kuti ateteze kutumizidwa kwa data mumanetiweki apakompyuta: chipangizocho chimapereka mabowo a RJ45 komanso zolumikizira za LSA-PLUS. Kuti titeteze mizere yolumikizirana ndi kulumikizana komanso zida za I&C ndi zowongolera pamizere yopanga, makina, ndi zida zofunikira, timalimbikitsa kugwiritsa ntchito Mndandanda wa FLD2 omwe amateteza ndi omanga mphezi komanso ma diode-voltage-suppression diode. Amaperekedwa m'mapangidwe osiyanasiyana okhala ndi mitundu ingapo yamitundu iwiri yamagetsi yamagetsi yamagetsi yamagetsi yamagetsi yamagetsi yamagetsi yamagetsi yamagetsi. Pazolumikizirana ndi RS 485 serial interface, timapereka chitetezo cha mizereyi pogwiritsa ntchito mndandanda wa FLD2 womwe umateteza zida zolumikizidwa motsutsana ndi ma transverse and longitudinal surge. Kuteteza makamera ndi makanema ophatikizira amakanema, makamaka pamakina achitetezo azamagetsi ndi zida zamagetsi zoteteza moto EPS imagwiritsa ntchito FLPD2 yopanda zida zazing'ono zamagetsi a Imax mpaka 6.5 kA. Kuteteza kwa zida zolumikizidwa ndi makina a antenna okhala ndi chingwe cha coaxial kuyenera kukhala ndi zotchinjiriza za surge. LSP imapereka zotetezera zingapo za coaxial zamitundu yosiyanasiyana yolumikizira ndi magwiridwe antchito omwe angagwiritsidwe ntchito m'mitundu yambiri yamapulogalamu. SPD iyi imakhala ndi omenyera mphezi omwe ali ndi Imax (8/20 )s) = 10 kA kuti ateteze kotsimikizika kalandiridwe ndi mawayilesi motsutsana ndi kuwomba kwa mphezi pafupi. Amapereka chisamaliro chapamwamba chazitsulo zosachepera 20 dB.

Nkhani yodziteteza ku ma surges siyophweka; kapangidwe koyenera kamadalira pazifukwa zingapo. Tikukupemphani kuti mulumikizane ndi omwe akuyimira malonda athu omwe angakonde kukulangizani posankha mtundu woyenera wa chitetezo kuti muteteze katundu wanu ndikuchepetsa kuwonongeka kwa katundu wanu.

Zofunikira pakugwiritsa ntchito Zipangizo za Surge Protective Devices (SPDs) mu Industrial Control Panels

Zipangizo Zowonjezera (SPDs) zimagwiritsidwa ntchito kwambiri muzitsulo zamagetsi. Tebulo lili m'munsiyi ndikufotokozera zamitundu ya SPD ndi momwe ingagwiritsidwire ntchito m'mapanelo pomwe palibe kufotokozera kwamachitidwe. Zofunikira pakuwerengera kwa Voltage ndi Nominal Discharge Current (NDC) za SPD zikuwonetsedwa patebulo pansipa. Ma SPD omwe amagwiritsidwa ntchito kunja kwaupangiri wa tebulo ili amafunika kufotokozera za Ndondomeko. Kutengera kuwunika kwa SPD, malangizowa atha kupitilizidwa ngati kuwunika kwaukadaulo kukuchitika.

Gome likugwira ntchito pa "Port-One" SPDs, zomwe ndizofala kwambiri. Pomwe SPD "Ma Port Awiri" imagwiritsidwa ntchito, idzakhala mtundu wololedwa patebulo pamwambapa, kutengera momwe gululi ligwiritsidwira ntchito, ndipo ingagwiritsidwe ntchito pamanambala ake, kuphatikiza Short Circuit Current Rating (SCCR). Ma doko awiri Mtundu wa 3 SPDs osadziwika ndi SCCR, amaganiza kuti ndi 1000A. Ngati chipangizochi chikuzindikiridwa ndi Chidziwitso 4 mu Tsambali la Tsamba la Zolemba (posonyeza kuti chitetezo chamtundu wakunja chikufunika), SPD iyi iyenera kufotokozedwa.
