Musiyano uripo pakati peACB neMCCB

Muchina wekupwanya mhepo (ACBuyemuputsi wedunhu wakaumbwa (MCCB) imidziyo miviri inowanzoshandiswa yekudzivirira macircuit mumasisitimu emagetsi. Kunyange zvazvo ese ari maviri achibatsira pakudzivirira macircuit kubva pakuwanda kwemagetsi, ma short circuit, nezvimwe zvinokanganisa, pane misiyano mikuru pakati pemacircuit maviri aya inoita kuti akwanise kushandiswa zvakasiyana.

Chekutanga, saizi dzeACB neMCCB dzakasiyana zvikuru. MaACB akakura muhukuru nehukuru uye ane ma ratings aripo pakati pe400A kusvika 6300A. Izvi zvinoita kuti akwanise kushandiswa muma network emagetsi, uko basa rawo riri rekuparadzira simba remagetsi nekudzivirira mitsetse nemidziyo yemagetsi kubva muzvikanganiso zvakasiyana-siyana. MaMCCB, kune rumwe rutivi, madiki muhukuru nehukuru uye ane ma ratings aripo pakati pe10A kusvika 800A. Anowanzo shandiswa kuchengetedza mitsetse yemagetsi nemidziyo kubva mukurema, ma short circuits uye undervoltages, uye anogonawo kudzivirira mashandiro emota.

Mumwe musiyano wakakosha pakati peACB neMCCB ibasa radzo rekudzivirira. Air circuit breaker intelligent tripper ine mabasa akawanda ekudzivirira akadai sekudzivirira kwenguva refu, kudzivirira kunonoka kwenguva pfupi, kudzivirira ipapo ipapo, kudzivirira pasi, kudzivirira overvoltage, uye kudzivirira kurasikirwa nechikamu. Pamusoro pemabasa ekudzivirira, ACB inopawo mabasa ekuyera akadai sekuyera ikozvino, kuyerwa kwevoltage, kuyerwa kwesimba, uye kuyerwa kweharmonic, pamwe nemabasa ekubatsira akadai sekunyevera pakutanga, kuzviongorora, kurekodha nhoroondo yezvikanganiso, uye mabasa ekuyedza. Pamusoro pezvo, ACB ine kugona kwekutaurirana kunobvumira kubatanidzwa muhurongwa hwemagetsi hwakakura. Kusiyana neizvi, ma molded case circuit breakers anonyanya kupa dziviriro yenguva refu, dziviriro yenguva pfupi (kudzivirira overload) uye dziviriro pakarepo (kudzivirira-circuit pfupi).

Mashandisirwo eACB neMCCB akasiyanawo. ACB inonyanya kushandiswa muma network makuru ekugovera magetsi nekuda kwesimba rayo remagetsi rakakwirira uye mabasa akasiyana-siyana ekudzivirira. Anoita basa rakakosha mukuona kuti masisitimu emagetsi anoshanda zvakachengeteka uye akavimbika nekudzivirira zvikanganiso zvakasiyana-siyana uye zvisingawanzoitiki. MCCB, kune rumwe rutivi, dzinoshandiswa munzvimbo dzekutengeserana nemaindasitiri uko simba remagetsi rakaderera rakakwana kudzivirira kubva pakuwanda kwemagetsi, mashort circuits, uye undervoltages. Anowanzo shandiswa kuchengetedza mitsetse yekuparadzira nemidziyo uye kudzivirira mashandiro ekutanga kwemota.

Muchidimbu, musiyano uripo pakati peACB neMCCB unogona kukonzerwa nehukuru hwazvo, mabasa ekudzivirira uye chiyero chekushandisa. ACB yakakura uye inogona kupa mabasa ekudzivirira akazara uye ekuyera uye yakakodzera kushandiswa mumagetsi ekuparadzira, nepo MCCB iri diki uye inogona kupa mabasa ekudzivirira anodiwa kune mitsetse midiki yekuparadzira nemidziyo. Kunzwisisa misiyano iyi kwakakosha pakusarudza mudziyo wekudzivirira wedunhu wakakodzera wesystem yemagetsi yakapihwa, kuve nechokwadi chekuti inoshanda zvakanaka uye yakachengeteka.
