Description

Vynález sa týká zapojenia zdrojovej sústavy s alternátorom a regulátorem využívaných v spojitosti so spalovacími motormi bez batérie.The invention relates to the connection of a power system with an alternator and a regulator used in connection with internal combustion engines without a battery.

V elektrickom výstroji motorových vozidiel a áalších zariadeniach so spalovacími motormi sa používajú ako zdroje elektrickej energie rotačné generátory. Tieto zdroje sú spravidla využívané v spolupráci s batériou, ktoré dodává potrebnú energiu vtedy, keď je napátie z generátore nižšie, ako napátie batérie. Najčastejšie používanými generátormi boli donedávna dynamé s permanentnými magnetmi, ktoré sú v súčasnosti nahradzované alternátormi s usměrňovačem. Záměna dynám za alternátory nespftsobuje problémy, ak zariadenie obsahuje batériu. V prípadoch, keď zdrojová sústava neobsahuje batériu a zdrojom elektrickej energie je dynamo s permanentnými magnetmi, stává sa problémom záměna takého generátore za alternátor vyžadujúci počiatočné vonkajšie nabudenie. Sú zariadenia, u ktorých je nemožné použiť batériu, a to z hladiska predpisov, prevádzkovej pohotovosti, nenáročnosti údržby, připadne hmotnosti. Záměna dynám za alternátory bez permanentných magnetov sa tak stává skoro nerieSitelná, napr. u přenosných požiarnych striekačiek.In the electrical equipment of motor vehicles and other internal combustion engine installations, rotary generators are used as electric power sources. These sources are typically used in conjunction with a battery that delivers the necessary power when the generator voltage is lower than the battery voltage. Until recently, the most commonly used generators were permanent magnet dynamos, which are currently being replaced by rectifier alternators. Replacing the pump with alternators does not cause problems if the device contains a battery. In cases where the power system does not contain a battery and the power source is a permanent magnet dynamo, it becomes a problem to replace such a generator with an alternator requiring an initial external energization. There are devices where it is not possible to use the battery in terms of regulations, operational readiness, low maintenance, or weight. Replacing the pump with permanent magnet alternators becomes almost impossible to solve, e.g. for portable fire-fighting syringes.

Tieto nedostatky odstraňuje zapojenie zdrojovej sústavy podle vynálezu, ktorého podstata spočívá v tom, že obsahuje alternátor s vonkajším budením, regulátor, magneto, tvarovací obvod a ochranný filtračný obvod, ktoré sú zapojené tak, že nízkonapěťový výstup z magnete je spojený so vstupom tvarovacieho obvodu, ktorého výstup je spojený s výstupnou svorkou alternátore, pričom medzi výstupnou svorkou a kostrou je ochranný filtračný obvod. Ďalšie svorky regulátora a alternátore sú spojené bez změny voči známým zapojeniam. Vo větve medzi nízkonapaťovým výstupom magnete a výstupnou svorkou alternátore v sérii s tvarovacím obvodom mftže byť zapojené spínacie tlačldlo. Nízkonapěťový výstup magnete mftže byť spojený s jedným polom skratovacieho tlačidla, ktorého druhý pól je spojený s kostrou.These drawbacks are overcome by the wiring of the power supply system according to the invention, which comprises an external excitation alternator, a controller, a magneto, a forming circuit and a protective filter circuit, which are connected such that the low voltage output from the magnet is connected to the forming circuit input. the output of which is connected to the alternator output terminal, wherein there is a protective filter circuit between the output terminal and the frame. The other terminals of the controller and the alternator are connected unchanged to the known wiring. A switch button can be connected in the branch between the low voltage output magnet and the alternator output terminal in series with the shaping circuit. The low voltage magnet output can be connected to one field of the shorting button, the other pole of which is connected to ground.

Riešenie podle vynálezu umožňuje náhradu dynám za alternátory bez permanentních magnetov najma v zástavách, ktoré nemajú betériu. V prípadoch, že v zariadení so spalovacím _Lmotorom je používané magneto ako zdroj vysokého napětia pre zapal'ovaciu sústavu, dOjde prí záměně dynama za alternátor k zníženiu hmotnosti celého zariadenia s možnosťou dodávania vyššieho elektrického výkonu.The solution according to the invention makes it possible to replace the pumps with alternators without permanent magnets, in particular in non-betained flags. In cases where the device with an internal combustion engine _L is used as a magneto high voltage source for sparking system, confusion occurs when a dynamo alternator to weight around devices with higher supply of electrical power.

Činnosť zdrojovej sústavy podTa zapojenia na obrázku v spojeni so spalovacím motorom je nasledovná:The operation of the power system according to the connection in the figure in connection with the internal combustion engine is as follows:

Vonkajším mechanickým působením je roztočený klukový hriadel' motora, ktorý je pomocou převodu spojený s rotorom magnete £. Otáčaním rotora magnete £ sa v cievkach magneta indukuje napatie, a to na nízkonapěťovom výstupu 11 nízké a na vysokonapaťovom vývode £g vysoké, ktoré je odvádzané do zapalovania. Přeskočením iskier na sviečkach sa nastartuje motor, ktorý otáča rotorom magneta £ a alternátorom £. V alternátore £, ktorý nemá permanentně magnety a nie je spojený s nízkonapěťovým výstupom 1 1 magneta £ sa neindukuje žiadne napatie. časť elektrickej energie z magneta £ je po uzavretí vodivej cesty, stlačením tlačidla, z nízkonapěťového výstupu 11 cez tvarovací obvod g dodávaná do alternátore £. Tým důjde k nabudeniu alternátore £, ktorý si cez regulátor g dodává potřebný prúd do budiaeeho vinutia 41 pre vlastné budenie a nie je už potřebné odoberať prúd z magneta £.The external mechanical action is the cranked shaft of the motor, which is connected to the magnet rotor 6 by means of a transmission. By rotating the magnet rotor, voltage is induced in the coils of the magnet at low-voltage output 11 low and at high-voltage terminal 8g high, which is diverted to ignition. Jumping the spark plugs on the spark plugs starts the engine, which rotates the magnet rotor 6 and the alternator 6. No voltage is induced in the alternator 6 which does not have permanent magnets and is not connected to the low voltage output 11 of the magnet 6. part of the electrical energy from the magnet 6 is supplied to the alternator 8 after closing the conductive path, by pressing a button, from the low voltage output 11 via the shaping circuit g. This causes the alternator 6 to be energized, which supplies the required current to the excitation coil 41 for its own excitation via the regulator g, and it is no longer necessary to draw the current from the magnet 8.

Tvarovací obvod g upravuje veTkosť a tvar napětia a tým aj veTkosť a tvar prúdu pri nabudzovaní z magneta £ do alternátora £. Ak je v tejto vetve zaradené spínacie tlačidlo g, stačí pre počiatočné nabudenie alternátora £ krátkodobé stlačenie spínacieho tlačidla g pri otáčkách rotoru alternátora £. Po nabudení je výhodné túto vodivá cestu prerušiť, aby magneto £ dodávalo všetku energiu do zapaTovaoieho obvodu. Ochranný filtračný obvod 8 zabezpečuje vhodný tvar výstupného napětia. Skratovacie tlačidlo £ slúži na vypínanie motora a tým aj celej zdrojovej sústavy. Po spojení jeho kontaktov důjde k spojeniu nízkonapěťového výstupu 11 z magneta £ s kostrou £ a magneto £ přestane dodévať potřebná energiu do zapalovacej sústavy, čím důjde k zastaveniu motora.The shaping circuit g adjusts the size and shape of the voltage and hence the size and shape of the current when energized from the magnet 4 to the alternator 6. If a switch button g is included in this branch, it is sufficient to briefly press the switch button g at the alternator rotor speed to initially energize the alternator 8. Upon energization, it is preferable to interrupt this conductive path so that the magneto delivers all the energy to the ignition circuit. The protective filter circuit 8 ensures a suitable shape of the output voltage. The shorting button 8 is used to switch off the motor and thus the entire power system. When its contacts are connected, the low voltage output 11 of the magnet 4 is connected to the frame 8 and the magneto 8 stops supplying the necessary energy to the ignition system, thereby stopping the engine.
