Mashandiro anoita MCB

Nhasi, tichanyatsoongorora mashandiro akaomarara emadiki ecircuit breakers (MCB) uye dzidza kuti dzinoita sei basa rakakosha mukuchengetedza macircuit nemidziyo zvakachengeteka. MCBs zvishandiso zvidiki zvinodzivirira macircuit kubva ku overcurrent ne short circuit. Zvakagadzirirwa kuchengetedza mitsetse nemidziyo kubva mukukuvadzwa kunogona kuitika nekuvhiringidza kufamba kwemagetsi kana adarika mwero wakachengeteka. Muchinyorwa chino, tichatarisa pamisimboti miviri mikuru yekudzivirira mukati memaminiature circuit breakers: kudzivirira overload ne short-circuit protection, uye kuongorora kuti misimboti iyi inoshanda sei pamwe chete kuchengetedza kushanda kwakachengeteka uye kwakanaka kwemasystem emagetsi.

Kutanga, ngatinzwisise musimboti wekudzivirira overload. Basa guru rekudzivirira overload nderekudzivirira current mucircuit kuti isapfuure simba rayo rakatarwa. Kana current ikadarika rating, inogona kukonzera kuti waya nemidziyo zvipise zvakanyanya, zvichikonzera njodzi huru yemoto. Musimboti wekudzivirira overload muMCBs wakavakirwa pamhedzisiro yekupisa. Kana current mucircuit ikapfuura kukosha kwakatarwa, chidimbu che bimetallic che thermal element mu miniature circuit breaker chinopiswa ne current, zvichiita kuti tembiricha yacho ikwire. Kana tembiricha yasvika padanho rakakosha, thermal element inoshanduka, zvichiita kuti bimetal ikotama kumusoro, ichisunda lever kuti ivhure latch yakakiyiwa. Chiito ichi chinoita kuti MCB igumbuke, zvichinyatso bvisa circuit uye kudzivirira overcurrent kuti isafambe zvakanyanya.

Tichienderera mberi kune musimboti wechipiri wekudzivirira, kudzivirira kwedunhu pfupi kunoita basa guru mukuziva nekukurumidza nekuderedza kukwira kwesimba remagetsi kamwe kamwe. Dunhu pfupi rinoitika kana simba remagetsi mudunhu rikakwira kusvika padanho rakakwirira zvakanyanya, kazhinji nekuda kwekutadza kana kuti dunhu pfupi riri pakati pewaya. Izvi zvinoisa njodzi huru kumidziyo nevashandi. MCB ine unit yekufamba nemagetsi inokwanisa kuona kuwedzera nekukurumidza kwesimba remagetsi. Kana dunhu pfupi rikaonekwa, kuburitswa kwesimba remagetsi kunogadzira simba rakasimba rekukweva rinokwevera ejector uye rinoita kuti latch yakakiyiwa ivhurike. Inodzima simba remagetsi ipapo ipapo kudzivirira mafungu makuru kuti asapfuure nepakati, ichidzivirira madunhu nemidziyo kubva mukukuvadzwa kunogona kuitika.

Muchidimbu, misimboti miviri yekudzivirira overload uye short-circuit kudzivirira inobatsira kuchengetedza kushanda kwakachengeteka uye kwakanaka kwemasekete nemidziyo. MCBs zvikamu zvakakosha zvemasisitimu emagetsi uye zvakagadzirirwa kuve nechokwadi chekushanda zvakanaka kwezvivakwa zvemagetsi uku zvichideredza njodzi dzinosanganisirwa ne overcurrent uye short circuits. Nekugadzirwa kwayo kudiki uye nzira dzekudzivirira dzine simba, MCB inopa mhinduro yakavimbika uye inoshanda yekudzivirira masisitimu emagetsi mumhando dzakasiyana-siyana dzekushandiswa, kubva padzimba dzekugara kusvika kumaindasitiri. Nekunzwisisa mashandiro akaomarara emaMCBs nebasa rawo rakakosha mukudzivirira masekete, tinogona kuve nechokwadi chekuchengetedzwa uye kugara kwenguva refu kwezvivakwa zvedu zvemagetsi.

Mutai Group yawana ruzivo rwemakore anopfuura gumi mukugadzira nekutengesamacircuit breakers, zvinobata, simba rechipirimaswichi ekutamisa otomatiki (ATS) nedzimwe nzvimbo dzakabatana. Tinotarisira nemoyo wese mukana wekushanda nemi.
