Trip curve ye circuit breaker

Kwakabva rwendo curve

Iyo pfungwa yekufamba curve yakatanga munyika yeIEC uye inoshandiswa kurongedza madiki madiki madiki (B, C, D, K uye Z) kubva kuIEC zviyero.Chiyero chinotsanangudza miganho yakaderera neyepamusoro yenzendo, asi vagadziri vane kusarudzika kwekuona chaizvo zvakatemwa mukati mezvikumbaridzo izvi zvinoita kuti zvigadzirwa zvavo zvifambe.Madhayagiramu erwendo anoratidza nzvimbo dzekushivirira uko mugadziri anogona kuseta mapoinzi erwendo rweanotyora wedunhu.

Trip curve ye circuit breaker

Hunhu uye mashandisiro ega ega curve, kubva pakunyanya kunzwa kune kushomeka, ndeaya:

Z: Rwendo pa2 kusvika ku3 nguva yakarongerwa ikozvino, yakakodzera kune yakanyanya kunzwisiswa zvikumbiro senge semiconductor michina

B: Rwendo pa3 kusvika ku5 nguva yakatarwa ikozvino

C: Rwendo pa5 kusvika ku10 nguva yakatarwa ikozvino, yakakodzera yepakati inrush ikozvino

K: Rwendo pa10 kusvika ku14 nguva dzakarongerwa ikozvino, dzakakodzera mitoro ine yakakwira inrush ikozvino, inonyanya kushandiswa kumamotor uye transformers.

D: Rwendo pa10 kusvika ku20 nguva yakarongerwa ikozvino, yakakodzera kune yakakwirira kutanga ikozvino

Kudzokorora "Kuenzanisa kwese IEC Trip curves" chati, unogona kuona kuti mafungu epamusoro anokonzera nzendo dzinokurumidza.

Iko kukwanisa kutsungirira impulse current chinhu chakakosha pakusarudza rwendo rwekutenderera.Mimwe mitoro, kunyanya mota uye ma transformer, inosangana nekuchinja kwechinguvana mune zvazvino, inozivikanwa seye impulse current, kana vanobatika vakavharwa.Zvishandiso zvinokurumidza kudzivirira, zvakaita se-b-trip curves, zvinogona kuona kuwanda uku sekutadza uye kubatidza dunhu.Kune idzi mhando dzemitoro, ma curves ekufamba ane magineti akakwira mapoinzi (D kana K) anogona "kupfuura" kuburikidza nekuwanda kwezvino, kudzivirira dunhu kubva parwendo rwenhema.
