Abstract
Vynález rieši približovací koncový spínač polohy pre automatizačné celky prevádzok pre priame spínanie relé, stykačov na napatie 0 — 220 V striedavých. Koncový snímač polohy pozostáva z usmerňovača, obvodu riadenia tyristora, jazýčkového kontaktu a tyristora. Jazýčkový kontakt zapojený medzi obvod riadiaceho napatia, tyristora a riadiacú elektrodu tyristora ovládá takto spínanie tyristora, ktorý spina relé, resp. stykač cez usměrňovač.The invention solves the approach limit switch positions for automation plant units for direct switching of relays, voltage contactors 0 - 220 V AC. The end position sensor consists of a rectifier thyristor, reed control circuit contact and thyristor. Reed contact connected between the voltage control circuit, thyristor and thyristor control electrode this controls the switching of the thyristor that is switching relays, resp. contactor via rectifier.
Description
Předmětům vynálezu je Koncový snímač polohy pozostávajúci z usmerňovača, tyristora, riadiaceho obvodu tyristora a jazýčkového kontaktu.The object of the invention is an end position sensor consisting of a rectifier, a thyristor, a thyristor control circuit and a reed contact.
Je známy koncový snímač polohy pozostávajúci len z jazýčkového kontaktu. Týmto snímačom nie je možné snímat priamo relé, pretože jazýčkový kontakt nevyhovuje pre napatie 220 V a indukovanú záťaž.An end position sensor consisting of only a reed contact is known. It is not possible to sense the relay directly with this sensor because the reed contact is not suitable for 220 V and induced load.
Tieto nedostatky nemá koncový snímač polohy podlá vynálezu, ktorého podstatou je to, že výstup obvodu riadiaceho napatia tyristora je připojený na riadiacu elektrodu tyristora cez jazýčkový kontakt, pričom tyristor a obvod riadiaceho napatia tyristora sú připojené na výstup usmerňovača, na ktorého vstupy je připojený zdroj striedavého napatia so záťažou.These drawbacks have no end position encoder according to the invention, which is based on the output of the thyristor control voltage circuit connected to the thyristor control electrode via a reed contact, the thyristor and thyristor control voltage circuit connected to the output of a rectifier to which inputs an AC source is connected. stress with stress.
Koncový snímač podlá vynálezu umožňuje priamo spínat relé a stykače na striedavé napatie do 220 V. Na tieto účely doteraz používané kontaktně snímače plné nahradzuje, je oproti nim spolehlivější, má váčší počet zopnutí a je výhodný aj do najťažších prevádzok, například prašných, výbušných.The end sensor according to the invention enables direct switching of relays and contactors to AC voltage up to 220 V. For this purpose, the contact sensors used so far fully replace, are more reliable, have a higher number of switching and are advantageous even in the most difficult operations, eg dusty, explosive.
Koncový snímač polohy podlá vynálezu js znázorněný na výkrese.The end position encoder according to the invention is shown in the drawing.
Medzi kladný a záporný pól usmerňovača 7 je připojený cez diodu 9 tyristor 3 a obvod 6 riadiaceho napatia tyristora 3. Výstup 5 obvodu 6 riadiaceho napatia tyristora 3 je cez jazýčkový kontakt 4 připojený na riadiacu elektrodu tyristora 3. Zdroj 11 striedavého napájacieho napátia a záťaž 10 sú připojené medzi vstupné svorky 1, 2 usmerňovača 7.Thyristor 3 is connected between the positive and negative rectifier 7 via diode 9 and thyristor 3 voltage control circuit 6. Output 5 of thyristor 3 voltage control circuit 6 is connected via reed contact 4 to thyristor control electrode 3. AC power supply 11 and load 10 they are connected between the input terminals 1, 2 of the rectifier 7.
Funkcia koncového snímača polohy 8 je nasledovná:The function of the end position encoder 8 is as follows:
Po ovplyvnení jazýčkového kontaktu 4 magnetickým polom tento zopne a privedie riadiace napatie z výstupu 5 obvodu 6 riadiaceho napátia tyristora 3 na riadiacu elektrodu tyristora 3. Tyristor 3 otvorí a zopne cez usměrňovač 7 záťaž 10 zapojenu cez zdroj 11 striedavého napájacieho napatia medzi vstupné svorky 1, 2 usmerňovača 7.When the reed contact 4 is affected by the magnetic field, it switches and applies control voltage from the output 5 of the thyristor voltage control circuit 6 to the thyristor control electrode 3. The thyristor 3 opens and closes the load 10 connected via the rectifier 7 via AC power supply 11 between the input terminals 1. 2 rectifiers 7.
Tyristor 3 je možné nahradit triakom.Thyristor 3 can be replaced by triac.
