Abstract
U zapojenia Je k prvej evorke slete pripojený asynohronny motor s hlavným vinutím a rozběhovým vinutím, kde obe vlnutla sú opatřené vý- vodmi. RieSeným problémom Je zvýSit spolehlivost rozběhu motora Jednoduohýml teohniokýml proetrledkami. To sa dosahuje tým, že k vývodu hlavného vlnutia motora Je připojený prvý odpor a oez dládu aj kondenzátor a druhý odpor, ktorý je svojou druhou stranou napojený na riadiaou elektrádu triaku, ktorého prvá anida Je spolu s druhou stranou prvého odporu a s druhou stíranou kondenzátora připojená k druhej evorke slete, zatial čo druhá anáda triaku Je připojená k vývodu rozběhového vlnutia motora.In the connection, an asynchronous motor with a main winding and a starting winding is connected to the first output, where both windings are provided with terminals. The problem to be solved is to increase the reliability of starting the motor with simple thermal relays. This is achieved by connecting a first resistor to the output of the main winding of the motor, and also a capacitor and a second resistor, which is connected with its second side to the control electrode of the triac, the first anode of which is connected to the second output, together with the second side of the first resistor and the second side of the capacitor, while the second anode of the triac is connected to the output of the starting winding of the motor.

Podia známého stavu techniky βύ spínače pomocného, rozběhového vinutia asynohrónnyoh motorov rioéené pomocou elektromagnetických relé, alebo zložitými elektronickými obvodmi. Známe JednoduohSie elektronické obvody nezabezpečujú spoíahlivý rozběh motora.According to the state of the art, βύ switches of the auxiliary, starting winding of asynohrónnyoh motors controlled by electromagnetic relays or by complex electronic circuits. Known simple electronic circuits do not ensure reliable engine start-up.
Uvedené nevýhody odstraňuje zapojenie spínača rozběhového vinutia pódia vynálezu, ktorého podstata spočívá v tom, že k vývodu hlavného vinutia asynohránnaho motora je připojený prvý odpor a oez diádu aj kondenzátor a druhý odpor, ktorý je avojou druhou stranou napojený na riadiaou elektrodu triaku. Prvá anoda tohto triaku jo spolu s druhou stranou prvého odporu a s druhou stranou kondenzátora připojená k druhéj svorke siete, zatiaí čo druhá an óda triaku je připojená k vývodu rozběhového vinutia motora. Ak »i to konJtrukoia aeynchrónneho motora vyžaduje, tnože byt medzi druhů anodu triaku a vývod rozběhového vinutia motora zapojený aj rozběhový kondenzátor.The above-mentioned disadvantages are eliminated by the connection of the stage winding switch of the invention, the essence of which consists in that a first resistor is connected to the main winding of the asynchronous motor and a capacitor and a second resistor connected to the triac control electrode by the other side. The first anode of this triac, together with the second side of the first resistor and the second side of the capacitor, is connected to the second terminal of the mains, while the second anode of the triac is connected to the starting winding of the motor. If the construction of the anechronous motor also requires this, a starting capacitor can also be connected between the types of anode of the triac and the terminal of the starting winding of the motor.
Výhodou zapcjenia spínača pódia vynálezu je spoíahlivý rozběh motora a odpojenie pomocného rozběhového vinutia až po dosiahnutí prevádzkového režimu, pričom konétrakcia aplnača je relativné jednoduchá a výrobně nenáročná.The advantage of switching on the stage switch of the invention is the reliable start-up of the motor and the disconnection of the auxiliary start-up winding only after the operating mode has been reached, the contraction of the filling being relatively simple and inexpensive to manufacture.
Příklady zapcjenia podlá vynálezu sú znázorněné na výkrese, na ktorom obr. 1 představuje achému zapojenia v základnéj podobě a obr, 2 alternativou achánu zapojenia β rozběhovým kondenzátorem.Examples of the connection according to the invention are shown in the drawing, in which FIG. 1 represents the connection achem in its basic form and FIG.
U zapcjenia podia vynálezu je k prvej svorke 10 siete připojený asynchrónny motor J_ a hlavným vinutím 2. a rozběhovým vinutím 2· Obe vinutia 2, J aú opatřené vývodmi 30, 40. K vývodu 30 hlavného vinutia £ asynohronneho motora 1 je připojený prvý odpor 4 a cez di&du 2 aJ kondenzátor 6 a druhý odpor £, ktorý je avojou drahou stranou napojený na riadiaou elektrodu triaku 8. Prvá an&da A1 triaku 8 Je spolu a druhou stranou prvého odporní 4 a a drahou stranou kondenzátora 6 připojená k druhej svorke 20 siete. Drahá anoda A2 triaku 8 je připojená k vývodu 40 rozběhového vinutia 2 motora 1, a to v prvom případe (obr. i) priamo a v drahom případe (obr. 2) oez rozběhový kondenzátor £. Na orientáoii diódy 2 nezáleží.In accordance with the invention, an asynchronous motor 11 and a main winding 2 and a starting winding 2 are connected to the first terminal 10 of the network. and via a diode 2 and J a capacitor 6 and a second resistor 6, which is connected by its expensive side to the control electrode of the triac 8. The first ana A1 of the triac 8 is connected to the second terminal 20 of the network together with the second side of the first resistor 4a and the expensive side of the capacitor 6. The expensive anode A2 of the triac 8 is connected to the terminal 40 of the starting winding 2 of the motor 1, in the first case (Fig. 1) directly and in the expensive case (Fig. 2) through the starting capacitor 6. The orientation of diode 2 does not matter.
Spínač pracuje tak, žo při stojaoom motora j. pre těká Jeho hlavným vinutím 2 velký prúd, ktorý vyvolá na prvom odpore 4 úbytok napatia, pričom diáda 2 v priepustnom smere nabije kondenzátor 6, z ktorého oez drahý odpor £ tečie prúd do riadiaoej elektrody triaku 8, oez ktorý tečie prúd do rozběhového vinutia 2 motora 2» zabezpečuje rozběh. Ke3 sa motor 1 rozběhne, prúd v jeho hlavnom vinutí 2 klesá, čo spo— «obuje zníženie úbytku napatia na prvom odpore 4 a po yýbití kondenzátora 6 oez drahý odpor 2 přestane tied prúd oez riadiaou elektrodu triaku 8, čo sposobí odpojenie rozběhového vinutia 2 motora 1. Po zastavení motora 1 sa cyklus opakuje. Riadiaou elektrodu a prvú anádu A1 triaku 8 možno přemostil odporem, ktorý zabezpečí ochranu prad samovolným zapínáním triaku 8, ktoré by mohlo nastal v dosledku raživýoh impulzov v sieti,The switch operates in such a way that, when the motor is stationary, a large current flows through its main winding 2, which causes a voltage drop across the first resistor 4, while the diode 2 charges a capacitor 6 in the forward direction, from which an expensive resistor 8, from which current flows into the starting winding 2 of the motor 2 ensures starting. When the motor 1 starts, the current in its main winding 2 decreases, which causes a reduction in the voltage drop across the first resistor 4, and after discharging the capacitor 6 from the expensive resistor 2, the current from the control electrode of the triac 8 ceases, causing the starting winding 2 to disconnect. motor 1. After stopping motor 1, the cycle is repeated. The control electrode and the first anadage A1 of the triac 8 can be bridged by a resistor, which ensures protection of the prad by spontaneous switching on of the triac 8, which could occur as a result of punching pulses in the network,
Zapojenie spínača podlá vynálezu Je vhodné pra motory malých výkonov pra strojky, čerpadlá, ohladiaoe agregáty a podobné účely.Switch connection according to the invention It is suitable for low-power motors for machines, pumps, cooling units and the like.
