Maitiro ekusarudza A, B, C, OR D madiki edunhu mabreaker MCB

Pane ina universal rwendo maitiro eminiature circuit breakers: A, B, C, uye D. Saka tinosarudza sei?

(1)TYPE A circuit breaker: 2 times the rated current, isingawanzo shandiswa, inowanzo shandiswa semiconductor kudzivirira (kazhinji shandisa fuse);Iyo inodaidzwa nhamba yenguva dzazvino, iko kukanganisa ikozvino, kutsungirira imwe nguva yekuchinja haifambi, hunhu hwayo ndeyekudzivirira kukanganisa ikozvino.

Sarudzo yekugumbusa mudziyo welow-voltage circuit breaker: tripping mudziyo mhando yecircuit breakerine over-current tripping device, under-voltage tripping device, shunt tripping device, etc. Overcurrent tripping device inogonawo kukamurwa kuita overload tripping device uye short-circuit current tripping device, uye ine kunonoka kwenguva refu, kunonoka, mapoinzi epakarepo, overcurrent. tripping device ndiyo inonyanya kushandiswa.The action current setting value ye overcurrent tripping device inogona kugadziriswa kana kugadziriswa, kazhinji nekutenderera kana kugadzirisa lever.Electromagnetic overcurrent tripping mudziyo une imwechete yakagadziriswa uye inogadziriswa maviri.Iyo yemagetsi overcurrent tripping mudziyo unowanzo kuchinjika.

Kutyora kugona kwe acircuit breakerinoreva kukwanisa kumirisana nepamusoro-soro yenguva pfupi, saka kukwanisa kuputsa kwemugadziri we rotary circuit breaker kunofanira kunge kwakakura kudarika pfupi-circuit current yemidziyo yayo yekudzivirira.Kufamba kwepamusoro-soro maererano nekuiswa uye kunogona kugoverwa mukugadzirisa kuiswa kana module, yakagadzirirwa kuisirwa rwendo rwefekitori uye wedunhu breaker inogadziriswa kuita organic yakazara, kamwe mushure mekunge vasiya yakayerwa ikozvino yerwendo inogadziriswa, uye modular yekumisikidza rwendo seyedunhu breaker yakaiswa modules, inogona kuchinjika, kuchinjika ndiko. yakasimba.

Instantaneous type: 0.02s, yekudzivirira dunhu pfupi;

Kunonoka kunonoka mhando: 0.1-0.4s, inoshandiswa kupfupika pfupi, kuchengetedzwa kwepamusoro;

Kunonoka kwenguva refu: isingasviki 10S, inoshandiswa kudzivirira kuwandisa;

Parizvino inowanzoshandiswaDZ seriesmhepo chinja (diki redunhu breakernekudzivirira kudonha), zvakajairwa kutaurwa ndezvi: C16, C25, C32, C40, C60, C80, C100, pakati pavo C inomiririra kubvisa hunhu hwazvino ndiC, kureva kusvetuka ikozvino, semuenzaniso C20 inoratidzira kusvetuka ikozvino 20A, rwendo hunhu. iri C curve, isa 3500W mvura hita kuti ude kusarudza dunhu rinotyora reC20 kazhinji, isa 6500W mvura hita kuti ude kushandisa dunhu reC32.

Circuit breaker inoshandiswa kuchengetedza waya uye kudzivirira moto, saka maererano nehukuru hwetambo yekusarudza pane maererano nesimba rekusarudzwa kwemagetsi.Kana iyo yedunhu inoputika yakakura, haizodziviriri waya.Kana waya yaremerwa, muparadzi wedunhu haasati asvetuka, izvo zvinounza njodzi dzakavanzwa kune kuchengetedzwa kwemba.

1.5 square waya neC10 switch

2.5 square waya ine C16 kana 20 chinja

4 square waya neC25 switch

6 square waya ine C32 switch

Formhepo inochinjainoshandiswa kumamotor ane mutoro, mhando D maitiro anofanirwa kusarudzwa kudzivirira iyo yakakwira yekutanga ikozvino yemota inotanga iyo iri 5-8 times kumusoro.

(2) B type circuit breaker: 2-3 times the rated current, inowanzoshandiswa kune yakachena resistive load uye yakaderera-voltage lighting circuit, inowanzo shandiswa kugovera imba bhokisi, kuchengetedza midziyo yemumba uye kuchengeteka kwemunhu, kushandiswa kushoma ikozvino.

(3) C type circuit breaker: 5-10 nguva iyo yakarongerwa ikozvino, inoda kuva mu 0.1 seconds kubva, maitiro emuvharidzi wedunhu ndiyo inonyanya kushandiswa, inowanzoshandiswa kuchengetedza mitsara yekuparadzira uye mitsara yekuvhenekera nepamusoro-soro yekuchinja ikozvino.

(4) D type circuit breaker: 10-20 times the rated current, kunyanya mukushandiswa kwemagetsi pakare pakare nharaunda yakakura, mhuri yese haishandiswe zvishoma, inokodzera kukwirisa pfungwa yekuremerwa uye yakakura kukanganisa ikozvino system, inowanzoshandiswa kudzivirira. midziyo ine high impact current.
