Cievka sa umiestní do nerezovej nádobky, překryje eutektickou zmesou hydroxidu draselného a hydroxidu sodného a zahřeje sa po dosiahnutie teploty 240 °C β výdrřou 1 ai 5 ainút na tejto teplote až po uvolnenie spečených zévitov od seba, na čo sa eutektické zmes odplavuje oplachovou tekutinou, ai po dosiahnutie neutrélnej reakcie oplachovej tekutiny tvorenej vodou alebo kúpelom glycerínu alebo anhydridu kyseliny ftélovej v haotnostnoa poaere 2:3 ohriatej na 130 cC. Nato sa běžným sp6soboa uvolněné závity spočítajd na počítadle navíjačky cievok v usporiadaní na opačnú funkciu pri rýchlosti odvíjania úmernej priemeru vodiča cievky prepočtom vztahu prieaeru a dížky vodiča a jadra cievky.The coil is placed in a stainless steel container, covered with a eutectic mixture of potassium hydroxide and sodium hydroxide and heated to a temperature of 240 °C, and held at this temperature for 1 to 5 minutes until the sintered turns are released from each other, after which the eutectic mixture is washed away with a rinsing liquid, or until a neutral reaction of the rinsing liquid formed by water or a bath of glycerin or phthalic anhydride in a 2:3 ratio heated to 130 °C is achieved. Then, the released turns are counted in the usual way on the coil winder counter in an arrangement for the opposite function at an unwinding speed proportional to the diameter of the coil conductor by calculating the ratio of the diameter and length of the conductor and the coil core.
Description
Vynález sa týká eposobu zisťovania povodného počtu závitov poškodenej transformátorové j cievky a rieši problém opravy a uvedeni* do funkcie povodných drahých elektrických zariadení dovážených bez základnej parametrovej a konštrukčnej dokumentácie.The invention relates to a method for detecting the flood number of turns of a damaged transformer coil and solves the problem of repairing and putting into operation expensive flooded electrical equipment imported without basic parameter and design documentation.
V praxi v dčsledku přetaženia alebo zhoršenia izolácie vodičov často dochádza k spálenin transformátorových cievok. Pri opravách takýehto spálených cievok pre nedostatek údajov o počtech závitech pČvodného vinuti* sú potom problémy. Deter*z používané sposoby, pri kterých sa spálená děvka rozřeže kolno směrem k vinutiu a počítajú ea jednotlivé konce vodiča sú namáhavé a vyznačuji sa nepřijatelnou toleranciou čo do počtu zlatěných závitov. ,In practice, transformer coil burns often occur due to overloaded or deterioration of the conductor insulation. There are then problems when repairing such burnt coils due to the lack of data on the number of turns of the original winding *. Deter * from the method used, in which the burned bitch cuts the knee towards the winding and counts and the individual ends of the conductor are strenuous and are characterized by an unacceptable tolerance in terms of the number of gold threads. ,
Uvedené nedostatky odstraňuje a problém rieši epéeob zisťovania parametrev cievky pre uvedený účel podlá vynálezu. Podztmta vynálezu spočívá v tom, že cievka ea umie8tni do nerezovej nádobky, překryje eutektiekou znesou hydroxidu draselného a hydroxidu sodného a zahřeje sa po dosiahnutie teploty 240 °C s výdržou 1 až 5 mlnút na tejto teplote až po uvolnenie spečených závitov od seba, na So sa eutektická zmee odplavuje oplachovou tekutinou, až po dosiahnutie neutrálnej reakcie oplachovej tekutiny tvorenej vodou alebo kúpelom glycerínu a anhydridu kyseliny ftálovej v hmotnoetnom leh pomere 2:3 ohriatej na 130 °C. Potom sa bežnýa epoeoboa uvolněné závity spočítajú na počítadle navíjačky cievok v ueporiadaní na opačnú funkciu pri rýchlosti odvíjenia úměrnej priemeru vodiča cievky prepočtom vztahu priemeru a dlžky vodiča a jadra cievky.The above-mentioned drawbacks are eliminated and the problem is solved by the method of determining the parameters of the coil for the stated purpose according to the invention. The object of the invention is that the coil ea is placed in a stainless steel container, covered with potassium hydroxide and sodium hydroxide by eutectics and heated to 240 DEG C. with a temperature of 1 to 5 minutes until the sintered threads are released from each other. the eutectic mixture is washed away with the rinsing liquid until a neutral reaction of the rinsing liquid formed by water or a bath of glycerol and phthalic anhydride in a weight ratio of 2: 3 heated to 130 ° C is achieved. Then, the conventional epoe or loose turns are counted on the bobbin winder counter in an arrangement for the opposite function at an unwinding speed proportional to the diameter of the bobbin conductor by recalculating the relationship between the diameter and the length of the conductor and the bobbin core.
Výhody vynálezu sú hlavně v tom, že sa umožní oprava a uvedenie do pčvodnej funkcie drahých elektrických zariadení dovážených bez základnej parametrovej a konstrukčně j dokumentácie.The advantages of the invention are mainly in that it is possible to repair and put into operation the original electrical equipment imported without basic parameter and construction documentation.
Vylúči ea nepresnosť a prácnost mechanického oddelovania vodičov a spočítaní* závitov, pri velmi poSkodených děvkách umožňuje vobec opravu ako prí menSom poSkodení. Chemická reakcí* přitom urýchli očištěnie pdvodnej kovověj konStrukcie pre novů montáž.It eliminates the inaccuracy and laboriousness of the mechanical separation of the conductors and the counting of the threads; The chemical reaction * accelerates the cleaning of the original metal structure for reassembly.
Příklad uskutečněni* epdsobu podle vynálezu:Example of carrying out the method according to the invention:
Spálená transformátorová cievka so spečenými závitaL na kostře z pertinaxu s hmotnostou 115 g sa uad.eetni v železnom kelímku alebo nerezovej nédobe a celá děvka sa překryje eutektiekou zmeaou KOH a NaOH v taken množstve, aby celá cievka bol* zakrytá v danoa případe 288,318 g zmesi a zahrieva sa do teploty 240 °C. Uvedená teplota sa udržuje do 5 minút od jej dosiabnutia. Po vychladnutí reakčnej sněd v nádobě sa odstráni reakčná znes z cievky jej uloženín do nádobky s kúpelom zkladajúdn ea z 2 hmotnostných dielov glycerolu a 3 hnotnostných dielov anhydridu kyseliny ftálovej, ohriatej na teplotu 130 °C. S dodatečným efektom možno odetránenie nezreagovanej zmesi uskutečnit uložením děvky do nerezovej nádoby, do ktorej přitéká a zároveň odtéká voda z vodovodu. Koniec oplachováni* vodou sa zisťuje na základe reakde vody, ktoré má byť neutrálna, pH = 7,0.A burnt transformer coil with sintered coils on a 115 g pertinax skeleton was placed in an iron crucible or stainless steel vessel and the whole bitch was covered with a eutectic mixture of KOH and NaOH in the amount taken so that the whole coil was covered in a given case of 288.318 g of mixture. and heated to 240 ° C. Said temperature is maintained within 5 minutes of reaching it. After the reaction mixture has cooled in the vessel, the reaction mixture is removed from the coil and placed in a bath vessel consisting of 2 parts by weight of glycerol and 3 parts by weight of phthalic anhydride, heated to 130 ° C. With the additional effect, the removal of the unreacted mixture can be carried out by placing the slurry in a stainless steel vessel, into which tap water flows and drains at the same time. The end of the water rinse * is determined by the reaction of the water to be neutral, pH = 7.0.
Po ukončení neutralizáde jedným z uvedených spoeobov sa cievka vysuší, do kostry cievky sa položí cez jej otvor dřevený kolík a celá cievka sa umieetní na navíjačke pre cievky, opatřenoj počítadlem. Podlá hrůbky povodného vodiča sa poton opatrné odvíja závit za závitem a postupné sa spočítá počet závitov povodnej izoláde pévodného vodiča.Upon completion of the neutralization by one of said spools, the spool is dried, a wooden pin is placed in the spool frame through its opening, and the entire spool is placed on a spool winder equipped with a counter. According to the thickness of the flood conductor, the thread is then carefully unwound thread by thread and the number of threads of the flood conductor insulation is gradually counted.
Vynález možno využiť pri opravách, renovádach a výroba nových elektrických zariadení vybavených vinutím z izolovaného vodiča v celej škále velkostí a druhov a pri akejkol’vek činnosti, včítane domácej dielenskej práce bez vybaveni*, prípravkov a pod.The invention can be used in repairs, renovations and the production of new electrical equipment equipped with insulated conductor windings in a whole range of sizes and types and in any activity, including domestic workshop work without equipment *, jigs and the like.
