Nhanganyaya
Kanakadiki chinjaKana yakabatidzwa kana kudzimwa, ka "spark" kemagetsi kanowanzoonekwa pakati pema "contacts". Iyi arc. Pasinei nehukuru hwayo hudiki, inogona kukanganisa hupenyu hwe switch uye kuchengetedzeka kwemidziyo. Kunzwisisa zvikonzero, njodzi dze arcs, uye nzira dzinoshanda dzekudzvinyirira zvakakosha pakuvandudza kuvimbika kwe micro-microphone. maswichi.
Chizvarwa cheArcs: "Small Spark" Kana Current Yakanganiswa
Kana kubatana kwe micro Kana chinja chikavhurwa kana kuvharwa, kuchinja kwemagetsi kamwe kamwe kunogona kukonzera kuti mhepo iri pakati pemacontacts ive ionized, zvichigadzira arc. Zvakafanana nemheni pazuva remvura, asi padanho diki. Chiitiko ichi chinonyatsooneka kana switch ichishandiswa kudzora zvishandiso zvine mitoro, senge mota kana ma light bulbs. Kana magetsi akakura uye voltage yakakwira, mukana wekuti arc iitike. Kupisa kunoonekwa nguva nenguva kana uchidzvanya switch yemumba muenzaniso wearc iyi.
Njodzi dzeArcs: "Muurayi Akanyarara" Anopedza Maswichi
MaArc anopisa zvakanyanya uye anogona kuputsa zvishoma nezvishoma pamusoro pemacontacts, zvichiita kuti asaenzane. Nekufamba kwenguva, izvi zvinogona kukonzera kusabatana zvakanaka, uko switch isingapindure kana yadzvanywa kana chiratidzo chikasashanda. Semuenzaniso, kana mabhatani ari pambeva akarega kushanda mushure mekushandiswa kwenguva refu, kazhinji zvinokonzerwa nekuti macontacts acho akapwanyika nearcs. Muzviitiko zvakakomba, arcs dzinogona kukonzera kuti macontacts anamatire pamwe chete, zvichidzivirira switch kuti isadzime uye zvichikonzera njodzi yekushanda kwemidziyo nguva dzose, kunyanya mumichina yeindasitiri nemidziyo yemotokari, uko zvikanganiso zvakadaro zvinogona kukonzera njodzi dzekuchengetedza.
Maitiro Ekudzvinyirira: Kuwedzera "Shield" kuSwitch
Kuti varwise ma arcs, indasitiri iyi yakagadzira nzira dzakasiyana-siyana dzinoshanda. Ma RC buffer circuits, anoumbwa nema resistors nema capacitors, anoshanda se "buffer pad" nekunwisa simba rinogadzirwa nema arcs, sekunge speed bump yekuchinja kwemagetsi, zvichideredza simba rema sparks. Varistors vanoshanda se "vachengeti vemagedhi," vanoramba vasingashande pasi pemagetsi akajairwa asi vachikurumidza kuita kana arc ikakonzera kukwira kwemagetsi kamwe kamwe, ichitsausa magetsi akawandisa uye ichidzivirira ma contacts. Solid-state relays, anoshandisa zvikamu zvemagetsi kudzora magetsi pasina ma mechanical contacts, anobvisa mukana we ma arcs uye anowanzo shandiswa muzvishandiso zvekurapa nema tools akanyatsonaka.
Mhedziso
Maitiro aya ekudzvinyirira anoita kuti maswichi anogara kwenguva refu uye akavimbika. Kuderedza kukanganiswa kwema arc kunogona kuderedza mukana wekutadza uye kuwedzera hupenyu hwemidziyo yemumba neyemaindasitiri. Nekufambira mberi kwetekinoroji, "simba rekuparadza" rema arc riri kuramba richideredzwa simba, zvichibvumira micro maswichi kuti ashande zvakanaka mune dzimwe nguva uye kuchengetedza chinyararire mashandiro akajairika emidziyo.
