1, pln\u00fd tlak priameho \u0161tartu<\/p>\n

V pr\u00edpade, \u017ee kapacita a za\u0165a\u017eenie siete umo\u017e\u0148uj\u00fa priame sp\u00fa\u0161\u0165anie pri plnom nap\u00e4t\u00ed, mo\u017eno uva\u017eova\u0165 o pou\u017eit\u00ed priameho sp\u00fa\u0161\u0165ania pri plnom nap\u00e4t\u00ed.

2, automatick\u00e9 spustenie dekompresie<\/p>\n

Pou\u017eitie autotransform\u00e1tora s viacn\u00e1sobnou dekompresiou, nielen na splnenie potrieb rozbehu r\u00f4znych z\u00e1\u0165a\u017e\u00ed, ale aj na z\u00edskanie v\u00e4\u010d\u0161ieho rozbehov\u00e9ho momentu, sa \u010dasto pou\u017e\u00edva na spustenie ve\u013ekokapacitn\u00e9ho motora v re\u017eime dekompresie.

  1. Y-\u0394 za\u010d\u00edna<\/li>\n<\/ol>\n

    V pr\u00edpade asynchr\u00f3nneho motora s klietkou s trojuholn\u00edkov\u00fdm statorov\u00fdm vinut\u00edm v be\u017enej prev\u00e1dzke, ak sa statorov\u00e9 vinutie pri rozbehu zapoj\u00ed do tvaru hviezdy a po rozbehu sa zapoj\u00ed do trojuholn\u00edka, mo\u017eno zn\u00ed\u017ei\u0165 rozbehov\u00fd pr\u00fad a zn\u00ed\u017ei\u0165 jeho vplyv na elektrick\u00fa sie\u0165. Tento sp\u00f4sob rozbehu sa naz\u00fdva rozbeh s dekompresiou do hviezdy a trojuholn\u00edka alebo jednoducho rozbeh do hviezdy a trojuholn\u00edka (rozbeh Y-\u0394).<\/p>\n

    Ke\u010f sa na \u0161tart pou\u017eije hviezdicov\u00fd trojuholn\u00edk, \u0161tartovac\u00ed pr\u00fad je len 1\/3 p\u00f4vodn\u00e9ho sp\u00f4sobu zapojenia trojuholn\u00edka. Ak sa pri priamom \u0161tarte meria \u0161tartovac\u00ed pr\u00fad 6 ~ 7Ie, pri \u0161tarte hviezdicov\u00fdm trojuholn\u00edkom je \u0161tartovac\u00ed pr\u00fad len 2 ~ 2,3-n\u00e1sobn\u00fd. To znamen\u00e1, \u017ee ke\u010f sa na rozbeh pou\u017eije hviezdicov\u00fd trojuholn\u00edk, aj rozbehov\u00fd moment sa zn\u00ed\u017ei na 1\/3 p\u00f4vodn\u00e9ho pri priamom rozbehu trojuholn\u00edkov\u00fdm zapojen\u00edm.<\/p>\n

    Vhodn\u00fd na \u0161tartovanie bez z\u00e1\u0165a\u017ee alebo s n\u00edzkou z\u00e1\u0165a\u017eou. V porovnan\u00ed s ostatn\u00fdmi v\u00e1kuov\u00fdmi \u0161tart\u00e9rmi je jeho kon\u0161trukcia najjednoduch\u0161ia a cena najlacnej\u0161ia. Okrem toho m\u00e1 re\u017eim rozbehu v hviezdicovom trojuholn\u00edku t\u00fa v\u00fdhodu, \u017ee ke\u010f je za\u0165a\u017eenie mal\u00e9, motor sa m\u00f4\u017ee spusti\u0165 v r\u00e1mci zapojenia do hviezdy. V tomto \u010dase sa menovit\u00fd kr\u00fatiaci moment m\u00f4\u017ee prisp\u00f4sobi\u0165 za\u0165a\u017eeniu, \u010d\u00edm sa m\u00f4\u017ee zlep\u0161i\u0165 \u00fa\u010dinnos\u0165 motora, a t\u00fdm sa u\u0161etr\u00ed spotreba energie.<\/p>\n

        Znalosti o motore \u010derpadla<\/span><\/b><\/strong><\/h2>\n

        1. Motor je zariadenie, ktor\u00e9 premie\u0148a mechanick\u00fa energiu na elektrick\u00fa (alebo naopak) alebo men\u00ed jednu \u00farove\u0148 striedav\u00e9ho nap\u00e4tia na in\u00fa. Z h\u013eadiska premeny energie mo\u017eno motor rozdeli\u0165 na transform\u00e1tory, motory, gener\u00e1tory a \u010fal\u0161ie tri kateg\u00f3rie.<\/p>\n

        2.Vzorec na v\u00fdpo\u010det elektrick\u00e9ho uhla a1 vzdialenosti \u0161trbiny je a1 = p \u00d7 360o\/Z. Je vidie\u0165, \u017ee elektrick\u00fd uhol a1 sa rovn\u00e1 p-n\u00e1sobku mechanick\u00e9ho uhla am.<\/p>\n

        3. Princ\u00edp redukcie vinutia transform\u00e1tora je: pred a po redukcii zabezpe\u010di\u0165, aby sa magnetomotorick\u00e1 sila vinutia nezmenila, a zabezpe\u010di\u0165, aby sa akt\u00edvny a jalov\u00fd v\u00fdkon vinutia nezmenil.<\/p>\n

        4. Krivka charakteristiky \u00fa\u010dinnosti transform\u00e1tora je charakterizovan\u00e1 maxim\u00e1lnou hodnotou, to znamen\u00e1, \u017ee ke\u010f sa premenliv\u00e1 strata rovn\u00e1 kon\u0161tantnej strate, dosiahne sa maxim\u00e1lna hodnota.<\/p>\n

        5. Sk\u00fa\u0161ka transform\u00e1tora bez za\u0165a\u017eenia sa zvy\u010dajne vykon\u00e1va pri prilo\u017eenom nap\u00e4t\u00ed a meria sa na strane n\u00edzkeho nap\u00e4tia.

        7. Ke\u010f transform\u00e1tor pracuje paralelne, princ\u00edp rozlo\u017eenia z\u00e1\u0165a\u017ee je: jednotkov\u00e1 hodnota z\u00e1\u0165a\u017eov\u00e9ho pr\u00fadu transform\u00e1tora je nepriamo \u00famern\u00e1 jednotkovej hodnote impedancie nakr\u00e1tko. Podmienkou toho, aby sa kapacita transform\u00e1tora mohla pri paralelnej prev\u00e1dzke plne vyu\u017ei\u0165, je, aby sa jednotkov\u00e1 hodnota impedancie nakr\u00e1tko rovnala a aby sa rovnali aj ich impedan\u010dn\u00e9 uhly.<\/p>","protected":false},"excerpt":{"rendered":"
