Nei uchiisa SCB (Surge Circuit Breaker) kumberi-kumagumo kweSPD (Surge Protective Device)

Chii chinonzi SCB?

SCB - Surge redunhu breaker kana SPD backup dziviriro

Nei SCB?

SCB yakabudirira kugadzirisa dambudziko repasirese rekuwedzera kwekuchengetedza chishandiso kutadza kufambisa rwendo.

Kushandiswa Kwechigadzirwa

Kusarudzika kusarudzika kwesimba rakapfuura frequency frequency uye mheni yazvino inogona kunyatso chengetedza iyo SPD kubva ipfupi-kutenderera uye kutenderera-kutenderera kweSPD nekuda kwechimiro chisina kujairika chinopfuura pamusoro-magetsi, zvichikonzera tsaona dzakakomba dzemoto.

Iko kusarudzika kusarudzika kwesimba rakapfuura frequency frequency uye mheni yazvino inogona kunyatso chengetedza iyo SPD kubva mukukonzeresa iyo SPD kutanga voltage kudonha pazasi pemagetsi ekupa magetsi, uye simba frequency leakage yazvino kuwedzera, zvichikonzera tsaona yemoto yakakomba.

Kana iyo SPD iine mheni yazvino, iyo yekunze disconnector haizokanganisika netsaona, kuitira kuti mheni dziviriro yemidziyo yemagetsi irambe iri munzvimbo inoshanda.

Chikamu chekushandiswa

Iyo SCB yakazvipira yekuchengetedza dziviriro inopa nyanzvi kuchengetedza kuchengetedza kweiyo SPD (Mheni Kudzivirirwa Kudziya) iyo inodzivirira iyo magetsi anowanikwa eiyo yekutanga, yechipiri neyechitatu nhanho. Inoshanda kune nzvimbo uko SPD mheni yekudzivirira michina yakaiswa, senge magetsi emagetsi emaindasitiri uye ehurumende kuvaka, magetsi, kutaurirana, nzira yekufambisa, petrochemical nemamwe maindasitiri.

Kushanda nheyo

SCB, yakasarudzika yekunze disconnector yeSPD, imhando yemidziyo iyo inogadzirwa zvinoenderana nechinyorwa 430.3 muIEC61643-4-43: inotora yakakodzera pamusoro - yazvino michina yekuchengetedza pamberi penjodzi dzinokonzerwa nedunhu. Inonyanya kugadzirisa matambudziko ayo kana achiteera mafashama kana kuyerera kwerwizi kunoitika muSPD, SCB inogona kukasira nekukurumidza, nepo mheni ichipfuura, SCB haigumbuke, SCB inoona kuti SPD haikonzere moto uye kuchengetedza kwemwenje kwemidziyo kunogara kwenguva refu, kugadzirisa matambudziko ekuti kune dziviriro bofu mune fesheni yazvino inoshandiswa zvakanyanya uye mabhureki ayo anoshandiswa sekunze disconnectors. SCB ndiyo yakakodzera inowirirana michina yemagetsi switching mhando SPD, voltage inodzora mhando SPD inoshandiswa yakaderera-voltage magetsi magetsi system.

Pasi rose vari kutora chikamu mukugadzirisa dambudziko iri:

Kana iko kupisa kweSPD kuchiitika, vekunze mabhureki haabatanidze, Uye kana mafashama achiyerera kuburikidza nePSD, ekunze mabhureki anodonhedza zvisizvo.

ChiGerman yakaita kuyedza kwemheni ikozvino kukanganisa mafuses uye mabhureki muna 1997. Green nzvimbo inoreva kubatana, nzvimbo yeorenji zvinoreva kusava nechokwadi, uye nzvimbo tsvuku zvinoreva kudamburwa.

IEC yakanyora uye yakagadzirisa muyero weSPD. Sub-komiti 37A yakagadzira Task Force 12 mumusangano weAustria-Vienna. kugadzirisa dambudziko rinowirirana pakati peanopwanya uye SPD.

Nyika zhinji dzakakomberedza izwi dzakaparura chidzidzo dambudziko rekushomeka kweMOVs (metal oxide varistors) SPD.

Kana kupera kweSPD kuchiitika, kuratidzwa kwemagetsi parameter ndeyekuti U_c kukosha kunodzora.
Kana U_c kukosha kunodzikira kumagetsi emagetsi, leakage yazvino ichawedzera zvakanyanya.
Kana simba rikaita serisina kujairika kwenguva pfupi pamusoro pemagetsi, zvinoita kuti SPD itange.
Kana iyo yazvino yazvino inopfuura 5A ichiyerera kuburikidza nePSD, kumhanya kwemwenje kuri kukurumidza kupfuura kupisa kupisa.

Kana yazvino inopfuura 5A ichipfuura neSDD, inogona kubata moto nekukasira, saka iyo SPD inoda switch switch switch iyo inoburitsa nekukurumidza kana iyo yazvino inopfuura 5A ichipfuura ichidzivirira moto!

Inoda kuti kana magetsi ariko achiyerera nepakati, haigumbuke, izvo zvinochengeta kushanda kuri kuita.

Kana kushomeka kweSPD kuchiitika kana kusati kwadonha ikozvino kunokonzerwa nesimba risingawanzo rasvika 5A, inogona kukurumidza kukurumidza.

Chii chinogona SCB kugadzirisa dambudziko

Iko kusanzwisisika pakati pemidziyo yekudzivirira mheni uye fuse kana kutyora?

Iyo tsika yechinyakare ndeyekubatanidza fiyuzi kana kutyora munhevedzano pamberi pemidziyo yekudzivirira mheni, panogona kunge paine kutadza kutarisana kana zvichiita saizvozvo.

Kana mheni yekudzivirira michina ichinge yadonha kana paine kuwanda kwemhepo kunoitika mudunhu rekuparadzira, mheni inodzivirira michina inozoita pfupi-kutenderedzwa kusvika pasi uye maFuses kana mabhureki haakwanise kudimbura nekukurumidza
Kana mheni ikaitika, fuse kana mabhureki haakwanise kumira simba renguva pfupi remheni iripo, nekuti yaishandiswa sezvinhu zvekugovera magetsi mukugadzirwa kwekutanga. Saka zviri nyore kuvakanganisa kana kuputika, zvichiita kuti mheni idzivirire isingashande.
Kana mheni yazvino ichidarika nemabreaker, iyo Kukosha kukosha kwakanyanya uye magetsi ekudzivirira haagone kuchengetedza michina zvakanaka.
Fuses kana mabhureki haakwanise kudambura musimba kuve kuiswa mutsetse we transformer. Kana dunhu pfupi rikaitika, havagone kutyora nekukurumidza.

SCB inogona kugadzirisa matambudziko mana panguva imwe chete

SCB, yakabatana mune dzakateedzana pamberi peSPD inogona kugadzirisa matambudziko mana panguva imwe chete.

Kana mheni yekudzivirira michina ikadzikira kana paine vhiriji yakawandisa inoitika mudunhu rekuparadzira, SCB inogona kukatanura nekukurumidza kudzivirira mheni yekudzivirira michina kubva pakupfura. Ikozvino kutyora kuri pasi pe3 A.
Kana mheni yazvino yapfuura, iyo SCB yakabatana mune dzakateedzana pamberi peSPD haigone kuchengeta kana kukuvara pasi pemheni yazvino ye100kA, ichichengeta iyo SPD iri mukushanda.
Kana mheni yazvino ichipfuura neSBB, iyo U_p kukosha kwakaderera kwazvo, kuenzana nemhangura nehurefu hwakaenzana.
Iko kutyora kugona kweSBB kunopfuura mapurasitiki ekupwanya, anosvika ku100kA.

Pane musiyano mukuru munguva uye kukura pakati pesimba frequency parizvino nekuwedzera. SCB inoshandisa mushe maparamende maviri aya kudzora magesi remagetsi, ichiwana basa rekugumburwa.

Kana imwe nguva ichichinjika inoyerera ichipfuura, iyo magnomaineti inogona kukamba zvokusarudza kuti icheke imwe yazvino.
Nekuti kumhanya kwekumhanya kwakanyanya, kumhanyisa kunopera pamberi pemagetsi emagetsi asati atora matanho Saka electromagnet iri mune yakagadzikana mamiriro uye SCB haigumbuke.
