Low voltage switch (yakaderera voltage circuit breaker) inonziwo otomatiki mhepo chinja kana otomatiki mhepo wedunhu breaker.Inobatanidza kutonga uye mabasa akawanda ekudzivirira.Kana mutsara uchishanda zvakajairika, unoshandiswa sechibatiso chemagetsi kuvhura uye kudzima dunhu.Kana yabatidzwa, yakaenzana nechikamu chewaya ine simba.Kana iyo dunhu iine pfupi dunhu, yakawandisa uye zvimwe zvikanganiso, inogona otomatiki kucheka dunhu rakashata.Naizvozvo, iyo yakaderera-voltage switch inogona kuchengetedza redunhu nemidziyo.
Tsanangudzo yemidziyo yemagetsi yakaderera-voltage: inotsanangurwa zvichienderana nehukuru hwevoltage, iyo yakatemerwa voltage muAC inofanirwa kunge iri pasi pe1200V, uye yakayerwa voltage muDC inofanira kunge iri pasi pe1500V.
Kushandiswa kwe-low-voltage switches kunogona kuita kuti simba remagetsi rishande zvakasimba uye zvakachengeteka.Iyo chaiyo classification ndeiyi inotevera:
Zvinoenderana neyakasiyana yemukati chimiro cheyakadzika-voltage switch, inogona kukamurwa kuita disconnect switch uye grounding switch.Iyo general control musimboti inodzorwa neiyo switch fuse.Zvichienderana neiyo nzira yekuzviparadzanisa nevamwe, inogona zvakare kushandiswa kurodha switch uye fuse switch.Zvinoenderana neakasiyana ekuvhara nzira dzekuchinja, inogona zvakare kukamurwa kuita yakavhurika uye yakavharwa switch.Muchisarudzo chekusarudza, zvinoenderana nemamiriro ezvinhu chaiwo.
Low-voltage isolating switch imhando yekuzviparadzanisa switch.Ndiyo inonyanya kushandiswa switch mune yakakwira-voltage switchgear.Inoita basa rakakosha pakugadzwa uye kushanda kwakachengeteka kwemagetsi emagetsi.
Paunenge uchibvisa mutoro wezvino, iyo yakaderera-voltage yekuzviparadzanisa switch haigone kudarika inobvumidzwa yekubvisa kukosha kwayo ikozvino.Low-voltage isolation switches ye general structure haibvumidzwe kushanda nemutoro, chete yakaderera-voltage yekuparadzanisa switch ine arc yekudzima makamuri inogona kubvumira diki diki rekusawanzo kutakura mutoro.Zvinokosha kucherechedza kuti matatu-chikamu short-circuit ikozvino mutsara apo yakaderera-voltage isolate switch iripo haifaniri kudarika yakataurwa dynamic uye thermal stability values.
Low voltage isolate switch function:
1.Kushandura kwekuzviparadzanisa kunogona kuva nekugadzirisa kwakanaka, kuitira kuti dunhu rose rive rakachengeteka uye rakachengeteka, uye vashandi vekugadzirisa kana vashandi vanogonawo kugadzirisa dunhu munguva.
2.Kuwedzera, iyo yakaderera-voltage isolation switch ine basa rekushandura dunhu, uye shanduko dzakadaro dzinoshandiswa zvakanyanya mumafekitori emagetsi.Muenzaniso ndeuyu: mutsara wekugadzira unofanirwa kushandura kurongeka kwezvakatemwa zvechigadzirwa kana modhi.Panguva ino, kushandura kwekuzviparadzanisa kunogona kushandura maitiro ekushanda kwedunhu nekucheka magetsi, kuitira kuti kuwedzere kubatsirwa kwedunhu.
3.Kuwedzera kune mabasa ari pamusoro apa, iyo yakaderera-voltage isolation switch inogonawo kubatanidza mutsara.Mune yakaderera-voltage midziyo yedzimba dzekugara kana zvivakwa zvakajairika, iyo yekuzviparadzanisa inoderedza yakavanzika njodzi yenjodzi dzekuchengetedza kuburikidza nekusashanda kwemaoko.Izvi zvinoita kuti hupenyu hwedu huve nyore uye kushanda kwekugovera simba uye kutapurirana.
Iyo grounding switch is switch inoshandiswa kubatanidza kana kucheka dunhu repasi remidziyo yemagetsi uye magetsi.Basa rayo guru nderekudzivirira kutadza kwepfupi-redunhu kana netsaona yekubatanidza magetsi emidziyo yemagetsi, kuchengetedza kuchengetedzwa kwevanhu uye kushanda kwakachengeteka kwemidziyo yemagetsi. Iwo chaiwo akakosha mabasa anotsanangurwa seanotevera:
1. Kudzivirirwa kwehurongwa
Mumagetsi emagetsi, kukanganisa kwepasi chinhu chinowanzoitika.Kana kukanganisa kwepasi kuchiitika mumagetsi emagetsi, kuchaita kuti kuderedzwa kwekushanda kwemagetsi emidziyo, uye zviri nyore kukonzera migumisiro yakakomba yakadai semoto.Panguva ino, shanduko yepasi inogona kukurumidza kugura dunhu repasi, kuitira kudzivirira kuwedzera kwekukanganisa uye kudzivirira kushanda kwakachengeteka kwemagetsi emagetsi.
2. Kudzivirirwa kwekuchengetedzwa kwemunhu
Kana kuvuza kuchiitika mucasing yemidziyo yemagetsi, dunhu repasi inzira ine njodzi inogona kukonzera tsaona sekukuvara kwemunhu kana kufa.Iyo switching switching inogona kucheka dunhu repasi munguva kana paine kudonha kwemagetsi, kuitira kudzivirira yazvino kuti isapfuure nemuviri wemunhu uye kuve nechokwadi chekuchengetedzwa kwemunhu.
3. Chengetedza midziyo
Mukuita mutsara kana kugadzirisa kwemidziyo uye kugadzirisa, kazhinji kuitira kuchengetedza kuchengetedzwa kwevashandi, kubatana pakati pemidziyo nemagetsi system kunofanirwa kutanga kugurwa.Panguva ino, switching yepasi inogona kugura zviri nyore dunhu repasi kuti ive nechokwadi chekuchengetedzwa kwevashandi uye nekugadzirisa kwakajairika kwemidziyo.
Muminda dzakasiyana, tsananguro yeyakaderera voltage switch ichave yakasiyana.Zvisinei, mabasa makuru e-low-voltage switch ndeaya: kushandura, kudzivirira, kutarisa kwekutonga uye kugadzirisa.
