Miniature circuit breaker imhando ye switchgear ye low voltage circuit, inoshandiswa kuchengetedza midziyo yemagetsi uye kuchengetedzwa kwemunhu.
Madiki emagetsi edunhu anogona kuiswa mukati meimba (somuenzaniso, mumakabati ekugovera) kana kunze (somuenzaniso, mumabhokisi ekugovera).
1. Kune marudzi matatu ekugadzirisa nzira: yakagadziriswa, mobile uye yakamiswa.
2. Ikozvino yakarongerwa yedunhu rinoputika rakakamurwa kuva N uye P marudzi, N ndiyo yemazuva ano ine chiyero chepamusoro chemazuva ano, P ndiyo yemazuva ano ine zvishoma zvishoma, uye N yakakamurwa kuva L, L, N i1,2. -3A, uye B iri 2A maererano neyakayerwa ikozvino.
Madiki madiki edunhu anogona kushandiswa mukugara, zvivakwa zvehofisi, mafekitori nedzimwe nzvimbo.
I. Kurongeka kwemadiki madiki emagetsi.
(1) Yakakamurwa neArc Inodzima Medium: Kune matatu Arc Inodzima Systems: Mhepo, Vacuum kana Air-vacuum Mixing.
Mhepo masisitimu akakodzera AC yakaderera-voltage yekugovera mitsetse ine rated voltages kusvika ku690V uye haigone kumira chero mhando yekutadza kwepfupi-yedunhu kana mitsetse (N) uye zero (D) yakabatana, sezvo paine huwandu hukuru hwemagasi anert mukati. mhepo.
Pamusoro pezvo, masisitimu ane rated voltages e690V (N) kana pamusoro (pamusoro pe1800V) haakwanise kupfuura nepapombi dzesimbi kana marata.
Vacuum sisitimu yakakodzera kune yakayerwa voltage kusvika 660V, yakakwira mutoro uye isina mutsara wekukanganisa.
(2) Yakarongedzerwa nenzira yekushanda: kune marudzi maviri: mashandiro emaoko uye otomatiki mashandiro.
Manual oparesheni: inoshandiswa kubatanidza kana kutyora yakajairika dunhu uye isina kujairika dunhu, bhuku rekushandisa riri kuburikidza nebhunu switch, mubato kana bhatani kuti uwane.
Kushanda otomatiki: kuburikidza nedunhu rinotyora chinja pane bhatani rekutonga, kuti uwane mabasa anodiwa.
(3) Yakakamurwa zvinoenderana nemusimboti wekushanda: zvinoenderana nemaitiro ekudyidzana pakati pevanobatika uye maitiro ekuita, iwo akakamurwa kuva marudzi maviri;
Imwe ndeyemakanika;imwe yacho inonzi electrodynamic.
Mechanical circuit breaker inonyanya kushandiswa ku50HZ AC, 660V DC, yakakwira voltage system.
Electrodynamic action circuit breaker inonyanya kushandiswa muAC 1000V system kana low voltage distribution line;mamwe marudzi akadai semafuse, reactors, switches anogona kunge ari over-current protection and control.
Electrodynamic action circuit breaker yakakamurwa kuita mhepo yekufambisa mudziyo uye giya rekufambisa mudziyo.
(4) Maererano nemhando ye arc yekudzima svikiro, kune marudzi matatu: air combustion arc extinguishing system, air arc yekudzima hurongwa uye magetsi inert arc yekudzima kamuri composite system.
Inert arc yekudzima masisitimu anogona kukamurwa kuita mapoka maviri: kusarerekera mutsara kuparadzaniswa uye kwaakarerekera mutsetse akatevedzana.Iyo yekutanga inogona kushandiswa mumasekete asina kwaakarerekera nekuda kwezvinangwa zvakasiyana, iyo yekupedzisira haigone kushandiswa mumitsara yese isina kwayakarerekera (sekugara uye zvivakwa zvehofisi), uye iyo yekupedzisira inonyanya kushandiswa mumhando dzese dzemagetsi mitsara (sezvivakwa zveindasitiri uye matura) kunze kwepekugara.
Iyo yemagetsi arc yekudzima system inogona kushandiswa mumasekete ese anoda kuchengetedza mutsara wemagetsi kubva pangozi yemagetsi;inogona kushandiswa mumatunhu ose anoda kuchengetedza mutsara wemagetsi kubva pangozi yemagetsi pasina basa rekudzivirira kana pasina basa rekudzivirira pasi pemamiriro ekushanda kwese.Iyo yemagetsi arc yekudzima system inogona kuumba "pfupi dunhu" pakati pesimba sosi, mutoro uye neurere mutsara, iyo inogona kugura chikanganiso chiripo nekukurumidza kuderedza kuwedzera kwekupisa mutoro.
(5) Kurongeka nebasa: kune unipolar uye multipolar breakers;mhando dzose dzinogona kushandiswa mumitsara yemagetsi kana kugovera makabati, anonzi single-phase uye multiphase circuit breakers (kureva, kuva nezvikamu zviviri kana kupfuura) uye maviri-phase circuit breakers (anozivikanwawo sematatu-phase circuit breakers);single-phase uye maviri-phase circuit breakers vane yavo yakakosha kudzora zvikamu, senge: matatu-phase ikozvino-inoganhura mabreaker breakers, nezvimwewo;maviri-phase circuit breakers anonyanya kushandiswa mukugovera masisitimu e10 kV kana pasi, kana sedziviriro switch mumakabati ekugovera e10 kV kana pasi.
(6) Yakarongedzerwa zvinoenderana nemamiriro ekushandisa: kune madiki uye makuru akayerwa ikozvino;
