1, pilna spiediena tie\u0161\u0101 palai\u0161ana<\/p>\n

Ja t\u012bkla jauda un slodze pie\u013cauj pilna sprieguma tie\u0161o palai\u0161anu, var apsv\u0113rt pilna sprieguma tie\u0161\u0101s palai\u0161anas izmanto\u0161anu. Priek\u0161roc\u012bbas ir \u0113rta vad\u012bba, vienk\u0101r\u0161a apkope un sal\u012bdzino\u0161i ekonomisks risin\u0101jums. Galvenok\u0101rt to izmanto mazas jaudas motoru palai\u0161anai, no ener\u0123ijas taup\u012b\u0161anas viedok\u013ca vair\u0101k nek\u0101 11kW motoram nevajadz\u0113tu izmantot \u0161o metodi.<\/p>\n

2, autom\u0101tisk\u0101s dekompresijas s\u0101k\u0161ana<\/p>\n

Autotransformatora daudzp\u0101rejas dekompresijas izmanto\u0161ana, ne tikai lai apmierin\u0101tu da\u017e\u0101du slod\u017eu palai\u0161anas vajadz\u012bbas, bet ar\u012b lai ieg\u016btu liel\u0101ku palai\u0161anas griezes momentu, bie\u017ei tiek izmantota, lai palaistu lielas jaudas motora dekompresijas palai\u0161anas re\u017e\u012bmu. T\u0101 liel\u0101k\u0101 priek\u0161roc\u012bba ir t\u0101, ka palai\u0161anas griezes moments ir liels, un, ja t\u0101 tinuma kr\u0101ns ir 80%, palai\u0161anas griezes moments var sasniegt 64% no tie\u0161\u0101s palai\u0161anas. Un palai\u0161anas griezes momentu var regul\u0113t ar v\u012bt\u0146u piesl\u0113g\u0161anu. To joproj\u0101m pla\u0161i izmanto ar\u012b m\u016bsdien\u0101s.<\/p>\n

    Ja startam tiek izmantots zvaig\u017e\u0146u trijst\u016bris, starta str\u0101va ir tikai 1\/3 no s\u0101kotn\u0113j\u0101s trijst\u016bra savienojuma metodes. Ja tie\u0161\u0101s palai\u0161anas starta str\u0101vu m\u0113ra 6 ~ 7Ie, tad, palai\u017eot ar zvaig\u017e\u0146u tr\u012bsst\u016bri, starta str\u0101va ir tikai 2 ~ 2,3 reizes liel\u0101ka. Tas noz\u012bm\u0113, ka, start\u0113jot ar zvaig\u017e\u0146u tr\u012bsst\u016bri, ar\u012b starta griezes moments samazin\u0101s l\u012bdz 1\/3 no s\u0101kotn\u0113j\u0101, kad start\u0113 ar tie\u0161o tr\u012bsst\u016bra savienojumu.<\/p>\n

    Piem\u0113rots palai\u0161anai bez slodzes vai ar nelielu slodzi. Sal\u012bdzinot ar citiem vakuuma starteriem, t\u0101 konstrukcija ir visvienk\u0101r\u0161\u0101k\u0101, un cena ir ar\u012b viszem\u0101k\u0101. Turkl\u0101t zvaigznes tr\u012bsst\u016bra starta re\u017e\u012bmam ir priek\u0161roc\u012bba, ka, ja slodze ir neliela, motoru var darbin\u0101t ar zvaigznes savienojumu. \u0160aj\u0101 laik\u0101 nomin\u0101lo griezes momentu var saska\u0146ot ar slodzi, kas var uzlabot motora efektivit\u0101ti un t\u0101d\u0113j\u0101di ietaup\u012bt ener\u0123ijas pat\u0113ri\u0146u.<\/p>\n

      Tas ir tiristora f\u0101zes mai\u0146as sprieguma regul\u0113\u0161anas principa izmanto\u0161ana, lai pan\u0101ktu motora palai\u0161anas sprieguma regul\u0113\u0161anu, ko galvenok\u0101rt izmanto motora palai\u0161anas kontrolei, labu palai\u0161anas efektu, bet augstas izmaksas. T\u0101 k\u0101 tiek izmantoti tiristoru komponenti, tiristoru darba harmoniskie trauc\u0113jumi ir lieli, tiem ir zin\u0101ma ietekme uz elektrot\u012bklu.<\/p>\n

      Turkl\u0101t sv\u0101rst\u012bbas elektrot\u012bkl\u0101 ietekm\u0113s ar\u012b tiristoru komponentu vad\u012btsp\u0113ju, jo \u012bpa\u0161i, ja vien\u0101 elektrot\u012bkl\u0101 ir vair\u0101kas tiristoru ier\u012bces. T\u0101p\u0113c tiristoru komponentu boj\u0101jumu bie\u017eums ir liel\u0101ks, jo tas saist\u012bts ar energoelektronikas tehnolo\u0123iju, t\u0101p\u0113c ar\u012b pras\u012bbas tehnisk\u0101s apkopes tehni\u0137iem ir liel\u0101kas.<\/p>\n

        Invertors ir motora vad\u012bbas ier\u012bce ar visaugst\u0101ko tehnisko saturu, vispiln\u012bg\u0101ko vad\u012bbas funkciju un lab\u0101ko vad\u012bbas efektu m\u016bsdienu motoru vad\u012bbas jom\u0101. Tas regul\u0113 motora \u0101trumu un griezes momentu, mainot elektrot\u012bkla frekvenci. T\u0101 k\u0101 tas ietver energoelektronikas tehnolo\u0123iju un mikrodatoru tehnolo\u0123iju, t\u0101 izmaksas ir augstas un pras\u012bbas apkopes tehni\u0137iem ir augstas, t\u0101p\u0113c to galvenok\u0101rt izmanto jom\u0101s, kur nepiecie\u0161ama \u0101truma regul\u0113\u0161ana un \u0101truma kontrole.<\/p>\n

        2.Formula, lai apr\u0113\u0137in\u0101tu elektrisk\u0101 le\u0146\u0137a a1 no slota att\u0101luma ir a1 = p \u00d7 360o\/Z. Var redz\u0113t, ka elektriskais le\u0146\u0137is a1 ir vien\u0101ds ar p reiz\u0113m meh\u0101nisk\u0101 le\u0146\u0137a am.<\/p>\n

        3.Transformatora tinuma samazin\u0101\u0161anas princips ir \u0161\u0101ds: pirms un p\u0113c samazin\u0101\u0161anas nodro\u0161in\u0101t, lai tinuma magn\u0113tiskais sp\u0113ks nemain\u012btos, un nodro\u0161in\u0101t, lai tinuma akt\u012bv\u0101 un reakt\u012bv\u0101 jauda nemain\u012btos.<\/p>\n

        6.Ja transformators darbojas paral\u0113li, nosac\u012bjumi bezslodzes un bez cirkul\u0101cijas ir \u0161\u0101di: attiec\u012bba ir vien\u0101da un piesl\u0113guma grupas numurs ir vien\u0101ds.<\/p>\n
