Circuit breaker inogadzirwa mumhando dzakasiyana-siyana dzemazuva ano, kubva kumidziyo inodzivirira maseketi emazuva ano kana midziyo yemumba yega yega, kuenda kuswitchgear yakagadzirirwa kuchengetedza high-voltage circuits inodyisa guta rose.
Liperinoita Miniature circuit breaker (MCB) - yakayerwa ikozvino kusvika 63 A, iyo inowanzoshandiswa mukugara, kutengeserana, mwenje wemaindasitiri.
MCBs kazhinji haaparadzwe panguva yekupfuura-ikozvino saka anogona kushandiswa zvakare. Iwo zvakare ari nyore kushandisa, achipa kuve nyore kwe 'on / off switching' yekuzviparadzanisa nedunhu uye sezvo kondakita achigara mukati mebhokisi repurasitiki, akachengeteka zvakanyanya kushandisa nekushanda.
MCB inematatu musimboti maitiro, Amperes, Kilo Amperes uye Tripping Curve
Overload Current Rating - Amperes (A)
Kuremedza kunoitika kana midziyo yakawandisa yakaiswa padunhu rimwe uye kudhirowa mamwe magetsi emagetsi kupfuura dunhu netambo zvakagadzirirwa kutora. Izvi zvinogona kuitika mukicheni, semuenzaniso kana ketero, dishwasher, hobho yemagetsi, microwave uye blender zvese zviri kushandiswa panguva imwe chete. Iyo MCB padunhu iri inocheka simba nekudaro kudzivirira kupisa uye moto mutambo nematerminal.
Mimwe mitemo:
6 Amp- chiyero chekuvhenekera matunhu
10 Amp- magetsi makuru emagetsi
16 Amp uye 20 Amp-Immersion heaters uye boilers
32 Amp- Ring Final. Izwi rehunyanzvi redunhu rako remagetsi kana zvigadziko. Imba yekurara miviri semuenzaniso inogona kunge iine 2 x 32A maseketi emagetsi ekuparadzanisa masokisi ekumusoro nepasi. Dzimba dzekugara dzakakura dzinogona kuve nechero nhamba ye32 A maseketi.
40 Amp- Vabiki / hobho yemagetsi / madiki madiki
50 Amp- 10kw Magetsi emagetsi / Anopisa mabhavhu.
63 Amp- imba yose
Liper Breakers inovhara huwandu kubva pa1A kusvika 63A
Short Circuit Rating - Kilo Amperes (kA)
Short Circuit mhedzisiro yekukanganisa kumwe kudunhu remagetsi kana mudziyo uye inogona kuve nengozi zvakanyanya pane kuwandisa.
MCBs inoshandiswa mukatizvemumba installationzvinowanzoyerwa pa6kAkana 6000 amps. Hukama huri pakati peyakajairwa voltage (240V) uye yakajairwa magetsi emidziyo yemumba zvinoreva kuti yakawandisa-ikozvino inokonzereswa nepfupi wedunhu haifanirwe kudarika 6000 amps. Zvisinei, mukutengeserana uye maindasitiri mamiriro, kana uchishandisa 415V nemichina mikuru, inofanirwa kushandisa10kArated MCBs.
Tripping Curve
Iyo 'Tripping Curve' yeMCB inobvumira nyika chaiyo uye dzimwe nguva inodiwa zvachose, kuwedzera musimba. Semuyenzaniso, nharaunda dzekutengeserana dzevaeni, michina mikuru inowanzoda kukwidzwa kwesimba kwekutanga kudarika yavo yakajairika kumhanya ikozvino kukurira inertia yemamota mahombe. Uku kuvhiya kupfupi kunotora masekonzi chete, kunotenderwa neMCB sezvo yakachengeteka munguva pfupi pfupi.
Panematatu musimboti Curve Typesizvo zvinobvumira kuvhiyiwa munzvimbo dzakasiyana dzemagetsi:
Type B MCBsdzinoshandiswa mukuchengetedzwa kwedunhu remumbauko kune kudiwa kushoma kwemvumo yekuvhiya. Kuwedzera kupi zvako kwakakura mumhoteredzo yemumba kungangove kukonzeresa chikanganiso, saka huwandu hwepamusoro hwazvino hunobvumidzwa hushoma.
Type C MCBsnzendo pakati pe5 uye 10 nguva yakazara yakazara ikozvino uye inoshandiswa mukatinzvimbo dzekutengeserana uye dzakareruka dzeindasitiriiyo inogona kuve nemasekete makuru ekuvhenekesa efluorescent, mashanduri uye michina yeIT yakadai seseva, maPC nemaprinta.
Nyora D MCBsdzinoshandiswa muzvinorema maindasitiri zvivakosemafekitari anoshandisa mahombe anomonereka mota, X-ray michina kana compressors.
Mhando nhatu dzese dzeMCB dzinopa dziviriro yekugumburwa mukati mechikamu chimwe chete chegumi chesekondi. Kureva kuti, kana kuwandisa uye nguva zvapfuura, iyo MCB inofamba mukati memasekondi 0.1.
Naizvozvo, Liper anogara achizadzisa zvese zvaunoda.
