Abstract
Vynález spadá do odboru stavby elektrických strojov točivýoh a týká sa konět štrukčného vyhotovenia zbieraoieho krúžku pre přívod budlaeeho prúdu do rotora hlavně synohrónneho generátora· Zbieraoí krúžok pozostáva z vnútornej časti, ktorá je vyhotovená vo formě prstenoa z konštrukčnej ocele a vonkajšej časti, ktorá je vyhoto - vená z nehrdzavejúoej ocele vo formě návarku na vonkajšlu plochu vnútornej časti.The invention belongs to the field of construction of rotating electrical machines and relates to the final structural embodiment of a slip ring for supplying alternating current to the rotor of a synchronous generator. The slip ring consists of an inner part, which is made in the form of a ring made of structural steel, and an outer part, which is made of stainless steel in the form of a weld on the outer surface of the inner part.

Vynález sa týká zbieracieho krúžku elektrických strojov toči-vých hlavně synchrónnych generátorov· V súčasnosti zbieracie krúžky hlavně synchrónnych generátorovea vyhotovujú výlučné z farebných kovov a to predovšetkým z elektro-vodnej médi, čo si vyžaduje značné výrobně náklady, pričom pri prí-padnom dlhšom odstavení stroje sa na povrchu krúžka, ktorý je v sty-ku a uhlíkom sa vytvoří oxidačné vrstva· Túto oxidačnú vrstvu jepotřebné zakaždým ddkladne odstrániť, aby nedošlo k znehodnoteniupovrchu krúžka pri iskrení medzi uhlíkom a krúžkom.BACKGROUND OF THE INVENTION The present invention relates to a collection ring for electrical machines of mainly synchronous generators. At present, the collecting rings of mainly synchronous generators are made exclusively of colored metals, in particular electro-aqueous media, which requires considerable production costs, and in the event of a prolonged shutdown of the machine an oxidation layer is formed on the surface of the ring which is in contact with the carbon · This oxidation layer is always required to be removed thoroughly to avoid deterioration of the ring surface when sparking between the carbon and the ring.
Uvedené nevýhody v súčasnosti známých zbieraeíeh krúžkov súv podstatnéj miere odstránené zbieracím krúžkom podl’a předložené-ho vynálezu· Podstatou vynálezu je, že zbieraeí krúžok pozostávaz dvoch častí a to vnútornej časti, ktorá je vyhotovená vo forměprstenca z konstrukčněj ocele a vonkajšej čaeti, ktorá je vyhoto-vená z nehrdzavejúcej ocele vo formě návarku na vonkajšiu plochuvnútornej časti·The aforementioned disadvantages of the currently known ring collectors are substantially eliminated by the collecting ring according to the present invention. It is an object of the present invention that the ring collects two parts, the inner part, which is in the form of a ring of structural steel and an outer part which is made of stainless steel in the form of a welded-on piece on the outer surface of the inner part ·
Riešením podlá vynálezu sa umožňuje výroba ocelových zbiera-cích krúžkov aj pre prevádzku stroja v stažených klimatickýchpodmienkach· Medzi povrchom krúžka podlá vynálezu a uhlíkom nastá-vá nižšie iskrenie ako u súčasného vyhotovenia, nakolko pdvodnýpovrch sa neznehodnocuje lunkrami pri oxidácii· Toto má za násle-dok aj predíženie životnosti uhlíkov a krúžkov· Riešením podlávynálezu sa dosahuje výrazného zníženia výrobných nákladov, hlav-ně úspory úzkoprofilového farebného kovu·The solution according to the invention makes it possible to produce steel collecting rings also for the operation of the machine in contracted climatic conditions. Between the surface of the ring according to the invention and the carbon, lower sparking occurs than in the current embodiment, since the original surface is not degraded by the lunches during oxidation. also extends the lifespan of the carbons and rings · The solution of the undercarriage is achieved by a significant reduction in production costs, especially savings of the narrow-profile colored metal ·
Na přiložených obrázkoch je znázorněný příklad vyhotoveniazbieracieho krúžku podlá vynálezu· Na obr· 1 je znázorněný náryszbieracieho krúžku umiestneného na hriadeli rotora· Na obr· 2 jeznázorněný rez zbieracím krúžkom·An example of an embodiment of a picking ring according to the invention is shown in the accompanying drawings. FIG. 1 is a front view of a picking ring located on the rotor shaft;
Zbieraeí krúžok X sa umiestňuje na hriadel £ rotora synchron-neho generátore a je od hriadela odizolovaný izolačným puzdrom i· - 2 - 222 933 K obvodovéj ploché £ zbieracieho krúžku 1 sú přiložené uhlíky 2»cez ktoré prúd prechádza do zbieracieho krúžku χ. Zbierací krú-žok X pozoetáva z dvoch Saští a to vnútornej časti 6, ktoré je vy-hotovené vo formě prstence z konátrukčnej ocele a vonkajáej Čas-ti 2.9 ktoré je vyhotovené z nehrdzavejúcej ocele vo formě návarkuna vonkajáiu plochu 8 vnútornej časti 6. Celné plochy 2 zbieracie-ho krúžku X sa zafarbia zhodne ako ostatné kovové časti rotora.The collecting ring X is placed on the shaft 6 of the rotor of the synchronous generator and is insulated from the shaft by an insulating sleeve 1 - 2 - 222 933. The coils 2 are applied to the circumferential flat collecting ring 1 through which the current passes into the collecting ring χ. The collecting ring X consists of two Saws, the inner part 6, which is made in the form of a ring of structural steel and the outer part 2.9 which is made of stainless steel in the form of a welded-on outer surface 8 of the inner part 6. 2 of the collecting ring X is the same as the other metal parts of the rotor.
