Abstract

Zariadenie zostavené z medzikusu opatřených vzduchovými kanálmi a z dvoch inverzných elektropneuventílov umožňuje spo1'ahlivý rozvod vzduchu pre plynulý a bezporuchový chod pneumotora regulácie transformátora u elektrických rušňov 25 kV 50 Hz.The device, assembled from an intermediate piece equipped with air channels and two inverse electropneumatic valves, enables reliable air distribution for smooth and trouble-free operation of the transformer control pneumotor in 25 kV 50 Hz electric locomotives.

Description

Vynález rieši ovládanie pneumotora regulácie transformátora navrhovaným medzikusom a inverznými elektropneuventílami.The invention addresses the control of a transformer pneumatic actuator by a proposed spacer and inverse electropneumatic valves.

Ovládanie pneumotora pre pohon regulácie transformátora na elektrických rušňoch pre jednofázový systém o napatí 25 kV 50 Hz je zostrojené dvomi elektropneuventílami a pomocou dvoch šupátiek umiestnených v medzikusoch upevněných na hlavách pneumotora. Kanálikmi tohoto medzikusu a šupátkami sa vykonává rozvod a přívod vzduchu do pneumotora. Pre deformáciu šupátiek alebo roztrhnutie, ich zlomenie, dochádza k častým poruchám v rozvode a přívode vzduchu do pneumotora, čím je znemožněná práca pneumotora. To má za následok znemožnenie prepínania odbočiek na transformátore elektrického rušňa a jeho vyradenie z prevádzky.Controlling the transformer pneumatic actuator on electric locomotives for a single-phase system with a voltage of 25 kV 50 Hz is constructed by two electropneuent valves and by means of two clamps placed in the intermediate pieces fixed on the heads of the pneumotor. The ducts of this spacer and the drains are used to distribute and supply air to the pneumotor. For deformation of flaps or breakage, breakage, frequent breakdowns in the distribution and air supply to the pneumotor making the pneumotor work impossible. This results in the switching of taps on the transformer of the electric locator and its decommissioning.

Poruchu na rozvodovom zariadení móžeme odstrániť len úplnou demontážou medzikusu, výměnou šupátiek a opatovnou montážou vo vysokonapaťovej časti elektrického rušňa. Tieto práce možno vykonávat len v beznapaťovom stave rušňa, jeho uzemnění a klude, stání.The breakdown on the distribution system can only be remedied by complete removal of the spacer, replacement of the drawer and care assembly in the high-voltage part of the electric locomotive. These works can only be carried out in a no-load condition of the locomotive, its grounding and resting, standing.

Uvedené nedostatky sú odstránéné zariadením pre ovládanie pohonu pneumotora regulácie transformátora, ktorého podstata spočívá v tom, že k medzikusu tvaru kvádru sú proti sebe upevněné inverzně elektropneuventíle, pričom v medzikuse sú vytvořené kanály pre rozvod média k pohonu pneumotora regulácie.The above mentioned drawbacks are eliminated by the device for controlling the drive of the transformer control pneumatic motor, the principle of which is that the cuboid shaped spacer is inversely mounted electropneuentially, wherein channels for the distribution of the fluid are provided in the intermediate section for driving the pneumotor of the control.

Použitím medzikusu zhotoveného len s kanálikmi sa odstráni poruchovost rozvodového systému pre pneumotor regulácie transformátora elektrických rušňov 25 kV 50 Hz, zníži sortiment náhradných dielov a odstráni prácnosť pri doterajších poruchách ako aj výrobě šupátkových komůr, ich puzdier a vlastných šupátiek.The use of a channel-only spacer eliminates the failure rate of the 25 kV 50 Hz electric locomotive transformer control system, reduces the range of spare parts, and eliminates the laboriousness of past failures as well as the production of box chambers, their housings, and their own drawers.

Chod regulácie transformátora v danom regulačnom rozsahu pomocou navrhnutého riešenia je rýchlejší a trvá 14 sec. Chod prepínača je plynulý a pravidelný. Pretože doba chodu v regulačnom rozsahu je kratšia ako u povodného riešenia šupátkami, ušetří sa aj elektrická energia, ktorej časť sa stráca pri přepínaní odbočiek v odporníkoch tohoto zariadenia. Zariadenie možno využiť aj v energetike, kde k regulácii odbočiek transformátora sa používá pneumotor.The operation of the control of the transformer in the given control range is faster and takes 14 seconds. Switch operation is smooth and regular. Since the run-time of the control range is shorter than that of the flood protection solution, it also saves electricity, part of which is lost when switching the taps in the resistors of this device. The device can also be used in power engineering, where a pneumotor is used to control transformer taps.

Na právej straně medzikusu 3 (obr. 4) sú vyústěné vzduchové kanály 7, 8, pričom kanál 7 je vyústěný v drážke. Na týchto plochách sú aj otvory so závitmi 10 pre upevňovacie skrutky 2 (obr( 3 a obr. 4] elektropneuventílov 4. Štvorcálcový pneumotor s usporiadaním valcov do V je daný do pohybu přivedením tlakového vzduchu cez otvorený elektropneuventíl 4 a kanálikom 6 v medzikuse 3. Inverzným elektropneuventílom z druhého valca pneumotora je otvorený výpustný kanál 8.In Fig. 1, an intermediate piece 3 is fastened to the head of the pneumatic motor 5 by screws 2, which is attached inversely to the sides of the electropneuent 4.
