Uguqula uneswitshi: Scope, iimpawu, iimpawu

Icebiso imele isixhobo ziguquka ukugqithisa yangoku kunye yesekethe ukuguqukela. Amaninzi, ukuba kufakelwa kwezo ndawo apho ufuna unikezelo amandla ungaphazanyiswa. tshintshela uguqula lisetyenziswa ezibhedlele, iivenkile isebe kunye namanye amashishini non-mveliso. into eqhelekileyo ukunyusa izixhobo ezindlwini lizwe.

Umsebenzi omkhulu benza okuchasene beesekethe - ukuthintela mfutshane-kombane. imodeli Universal ikuvumela ukuba bebobabini ngokuthe nkqo. tshintshela uguqula yenzelwe uthungelwano ombane beyantlukwano abucwangciswanga ngaphezulu 650 V ne DC ukuya ku-450 V. Beka benza okuchasene zeesekethe yolu didi kulula ngokwaneleyo. Ngokuqhelekileyo, iintambo ziqhotyoshelwe amavili. Xa singavulwanga isixhobo 160 A, esebenzisa Din-ngololiwe kunye mvaba elikhulu - ibha engathethekiyo.

Enye onobuhle kakhulu ethandwa - nitshintshe iswitshi OT40F3C. iinkcukacha zayo bahlangabezane ngokupheleleyo iimfuno zokhuseleko. Le peculiarity yesixhobo - utshintshe nje ngokukhawuleza ukuya kumgca backup. Oku kwenziwa ngokuzenzekela ngaphandle koncedo yomsebenzisi.

ezahlukeneyo breakers beesekethe

Onke amaza beesekethe mihla njengangoku yahlulwe ngokwamaqela amathathu:

• Flip;
• discontinuous;
• ingathityazwa.

flip miyalezo

Flip miyalezo ziyilelwe ukuba angadlulisela ombane phakathi iziphaluka ezibini okanye utshintshe nje ngexesha elifanayo imigca embalwa. isixhobo eso sifakwe kumasango ikhaka okanye ikhaka macala lokuvula. isikhundla detent ingaba omnye okanye emibini. Isicelo Knife sokuyivula uhlobo ingathityazwa ikuvumela ukugcina umbane kwinkqubo kwiimeko ezingxamisekileyo, okanye nangoko switsha intambo yokusebenza. Le azisebenzisele elidityaniswe kwiqela lenjongo engaphandle.

Izixhobo Burst Type

Imela Iintlobo frangible eyenzelwe ukudibanisa enye kuphela yesekethe ephumayo. Le azisebenzisele ukwakweli kwiqela lenjongo engaphandle. Ngoncedo lwabo, ukutya kwi izindlu kunye nezindlu afakelwa umbane. Kuyinto ezi zixhobo kakhulu ithandwa ngelo xesha, njengoko zisetyenziswa phantse nasiphi na isakhiwo zokuhlala. Ukongeza, le miyalezo beesekethe discontinuous zifakwa kwi switchboard ekhethekileyo.

Imela sokuyivula uhlobo ingathityazwa

Kuba wesekethe -phase yangoku kusetyenziswa iswitshi elungisa. Ngokuba uyakwazi ukunika unikezelo liqhawuke ngokupheleleyo amandla. Umthwalo isasazwa phakathi kwabo imigca embalwa ngamandla onke. izixhobo ezinjalo kungenziwa eziqhutshwa zombini ngesandla kwaye elawulwa kude.

iimpawu Design ukulungisa-sivula

miyalezo beesekethe Modern zixhotyiswe nge inkqubo imela umfowunelwa, apho kwisiphaluka iifoto spring esisigxina ziquka iimela yesinyithi. Xa usebenzisa inkqubo onjalo akukho ithuba lokudibana ngokwaphula indlela ngendlela engaqondakaliyo, oko kukuthi, phantsi ubunzima bayo. Qhuba full yesiphaluka ngesandla, nesetyenziswa, umzekelo, ukuhlolwa okanye ukulungiswa kwenkqubo umbane.

iimpawu technical

Onke amaza wesekethe mihla, kuxhomekeka kwinani izibonda zahlulwe zibe olulodwa, emibini kwaye ipali emithathu usebenzise indlela 1-2.

Kwakhona a uguqula utshintsho shintsho, ukuqala ukusuka kwindawo ezinjengeetheminali uxhulumaniso yangaphandle yahlulwe yaba kwisixhobo nkqo okanye isiphumo ngaxeshanye. Kukho iinketho nazo zidityanisiwe.

Sales babe miyalezo beesekethe kunye nabo abancedisayo, inceda ukukhusela ngokuchasene nomthwalo kunokwenzeka amandla okanye circuit elifutshane. Xa ukhupha izixhobo zikunikeza kabini-ikhefu inxenye olubonakalayo yombane, elinye icala kumqhubi feed kunye nezinye - umthwalo.

Ukuba kukho imfuneko kwisekethe ziguquka kwi ombane aphezulu, kucetyiswa ukuba afumane switsha ingathityazwa kunye ebizwa ngokuba yi-gumbi arc, ngaphakathi kuyo ucimayo le arc yombane, ngaloo ndlela sikuphephe ukungasebenzi.
