Kuburitswa kweARM5 series undervoltage

1, Basa rakananga remudziyo wekusunungura undervoltage mumuviri weMCCB
1. Kutarisa kusagadzikana kwemagetsi uye kukonzera kugumburwa
Kana voltage yemutsara yadzikira kusvika pa35% ~ 70% yevoltage yakayerwa (mukati mehuwandu hwemazuva ese, nemusiyano mudiki muzvipimo kubva kuvagadziri vakasiyana), kusveta kwe electromagnetic coil mukati mekuburitsa hakukwani, uye kukiya kwemechanical kunoburitswa kuti kusundire MCCB inofamba kuti ibvise nekukurumidzira circuit huru.
Kana voltage yanyangarika zvachose (kurasikirwa nevoltage, kudzimwa kwemagetsi), kugumburwa nekuvhurwa zvichatangawo pakarepo; Mushure mekunge voltage yadzoka payakajairika, circuit breaker haizovharike yoga uye inoda kudzoserwa patsva uye kuvharwa nemaoko kubvisa njodzi yekutumirwa kwemagetsi otomatiki.
2. Chinangwa chekudzivirira chikuru
Dzivirira michina kuti isatsve kana magetsi akaderera
Midziyo yemagetsi/yekuburitsa magetsi yakaita semota, macompressor, uye mafrequency converters zvinogona kudzikira kumhanya uye kuwedzera kwakanyanya kwemagetsi (rotor current yakakiyiwa) pasi pemamiriro eundervoltage. Kushanda kwenguva refu kunogona kukonzera kupisa kwakanyanya, kuchembera kweinsulation, uye kutopera simba. Kudzima kwemidziyo yekuburitsa undervoltage panguva yakakodzera kunogona kudzivirira zvikanganiso zvakadaro.
Dzivisa njodzi dzekuchengetedza dzinokonzerwa nekudzima magetsi kamwe kamwe uye kudzimwa kwemagetsi
Kana pasina munhu ari pabasa mushure mekudzima kwemagetsi, kufona kamwe kamwe kunogona kukonzera kuti michina itange yega, izvo zvinogona kukonzera kukuvara kwemuchina, kukuvara kwemuchina pasina mutoro, maitiro ekugadzira asina kurongeka, tsaona dzemoto nemagetsi. Kuvhara nemaoko kunodiwa ndiyo dhizaini yakakosha yekuchengetedza.
Kuchengetedza michina yemagetsi nemagetsi chaiyo
Kana zvinhu zvisina kusimba zvakanyanya, michina yePLC, Precision yakadai sema industrial control modules, ma instruments, servo systems, nezvimwewo zvinogona kusangana nekusawirirana kwedata, kutadza kudzora, uye kuputsika kwezvikamu. Kubviswa kwemidziyo nekukurumidza kunogona kudzivirira kukuvara kwehardware uye kutadza kugadzira.
Batana pamwe chete negridi yemagetsi uye logic yekudzivirira sisitimu
Kana voltage yegrid yemagetsi ikachinja zvakanyanya uye paine kudzikira kwevoltage yekutadza kwenzvimbo, bvisa mitoro isiri yakakosha kuti uderedze kumanikidzwa kwekudzoreredzwa kwegrid yemagetsi, kudzivirira kuwedzera kwenzvimbo yekutadza, uye kuve nechokwadi chekuti magetsi edunhu akakosha anotarisirwa.
2, Basa rose riri muhurongwa hwekugovera/kugovera
Kuburitswa kwemagetsi asina simba hakusi chinhu chimwe chete, asi chikamu chakakosha chekuchengetedzwa kwekuchengetedza, simba remagetsi rakarongwa, uye manejimendi yemidziyo yekabati rekugovera. Mabasa ayo ehurongwa ndeaya anotevera:
1. Iva nechokwadi chekuti chinangwa chekuchengetedza munhu nemidziyo
Kabhineti yekugovera ndiyo nzvimbo huru yehurongwa hwekugovera magetsi. Njodzi dzekuwanda kwemidziyo, kupfupika kwemagetsi, uye kupisa kwemagetsi kunokonzerwa nekusashanda zvakanaka kwemagetsi zvichapararira zvakananga kukabhineti yese uye kunyange muworkshop. Kuburitswa kwesimba remagetsi, sekudzivirira kwemberi, kunogona kudzima dunhu pakutanga kwekusashanda zvakanaka kwemagetsi, zvichideredza mukana wekuvhunduka kwemagetsi, moto, uye tsaona dzemakanika kubva kunobva magetsi.
2. Shandisa dziviriro yakarongwa uye kudzima magetsi edunhu rekugovera
Kabhineti yekugovera inowanzo kamurwa kuita main coming circuit breakers nemabranch circuit breakers. Midziyo yekuburitsa magetsi pasi pevoltage ine miganho yakasiyana inogona kugadziriswa kuti iwane graded release: ma non-essential assistant circuits anobviswa kutanga, nepo ma key circuits akadai se main equipment, main protection, uye emergency lighting zvichichengetwa kuti magetsi apihwe. Kudzivirira low voltage mucircuit imwe chete zvichikonzera kuti kabhineti yese ne dividend room zviputse, kuderedza scope yekudzima kwemagetsi, uye kuvandudza kuenderera mberi kwemagetsi.
3. Chengetedza maitiro ekugadzira uye kugadzikana kwehurongwa
Mitsetse yekugadzira inoenderera mberi, mafekitori emakemikari, masisitimu echando, michina yekurapa, nezvimwewo hazvitenderwi kutanga kana kumira zvisina kurongeka. Kugumburwa kwemagetsi asina simba kunogona kudzivirira michina kushanda mumamiriro ezvinhu ane hutachiona hwemagetsi, kudzivirira kurasikirwa kwechigadzirwa, kukanganiswa kwemaitiro, uye tsaona dzehutano.
Pamichina yakabatana yakaita semapombi emvura, mafeni, uye macompressor emhepo, inogona kudzivirira michina yakawanda kuti isashande yakamanikidzwa panguva imwe chete, zvichikonzera kumanikidzwa kusina kujairika mu network yemapaipi, kurira kwemayuniti, uye kuomarara kwesystem.
4. Batira pamwe chete nepfungwa dzechipiri dzekudzora nekushanda kwekabhineti yekugovera
Yakabatana ne voltage meter, intermediate relay, uye ruzha nechiedza chekabati rekugovera, alarm inoburitswa panguva imwe chete kana voltage isina kunaka, zvichiita kuti vashandi vekushanda nekugadzirisa vaongorore matambudziko e circuit, transformer, uye magetsi epamusoro.
Hunhu hwekuvharwa kwemagetsi nemaoko hunoda kuti vashandi vekushanda nekugadzirisa vasimbise kudzoreredzwa kwemagetsi uye kutadza kwemidziyo vasati vatumira magetsi, vagadzirise maitiro ekushanda, uye vaderedze kusashanda zvakanaka uye kutapurirana kwemagetsi nezvikanganiso.
5. Magadzirirwo emagetsi akagadzirirwa mamiriro chaiwo
Munzvimbo dzakakosha dzakadai sezvivakwa zvirefu, migodhi, minda yemafuta, nzvimbo dzekushandira makemikari ane njodzi, makamuri ekuvhiyira ezvipatara, nezvimwewo, kuchengetedzwa kwemagetsi asina simba kunodiwa pakuchengetedza, kunoshandiswa kudzivirira kuputika, moto, uye tsaona dzehutano dzinokonzerwa nekudzimwa kwemagetsi netsaona, zvichienderana nemitemo yekuchengetedza magetsi uye mitemo yeindasitiri.
