Autor vynálezu BULLA PA VOL ing. a SLAVIK IVAN ing. CSc., NOVÁ DUBNICA (94) Bočník s nízkou indukčnosťou a kontaktným chladenim 1Author of the invention BULLA PA VOL ing. And SLAVIK IVAN ing., NEW DUBNICA (94) Low inductance shunt and contact cooling 1
Predmetom vynálezu je bočník s nízkouindukčnosťou, určený na snímanie prúdovs rýchlymi změnami. Bočník je vytvořenýkombináciou odporového a dobré vodivéhomateriálu a jeho chladenie je vyriešené při-tlačením na stenu zariadenia cež izolačnúpodložku.The subject of the invention is a low-inductive shunt designed to sense currents with rapid changes. The shunt is formed by a combination of a resistive and a good conductive material and its cooling is resolved by pressing on the wall of the device rather than the insulating pad.
Doteraz známé bočníky s nízkou indukč-nosťou majú celu aktívnu časť z odporové-ho materiálu a konstrukčně sú vyhotovenétak, že sú priamo chladené okolitým vzdu-chom bez zvláštnych opatření na odvod tep-la.The low inductance shunts known so far have an active part of resistive material and are constructed in such a way that they are directly cooled by the ambient air without special heat removal measures.
Podstata vynálezu spočívá v tom, že boč-hík pozostáva v podstatě z dvoch pásovplechu, z ktorých jeden je z odporovéhomateriálu s nízkým teplotným koeficientomodporu a druhý z běžného dobře vodivéhomateriálu, ako je napr. med'. Oba pásy súS'polu dobře vodivo i mechanicky spojenéspájkovaním, zváraním, nitovaním alebo po-dobné a sformované sú do tvaru písmenaU, čím sa docieli nízká vlastná indukčnosťbočníka. Vývody sú usporiadané tak, že je-den sa připojí na odporový plech a druhýna plech vodivý. Medzi obomi plechmi jeizolačná vložka. Celý bočník je svojou od-porovou stranou cez izolačnú podložku sdobrou tepelnou vodivosťou a odolnosťouvoči vysokej teplote přitlačený na stenu za- 2 riadenia, ktorá je obvykle kovová, a týmsa zabezpečuje jeho chladenie.The essence of the invention is that the sidewall consists essentially of two waistcoats, one of which is a low temperature coefficient resistive material and the other one of a well-known conductive material such as honey. Both strips are well conductively bonded mechanically by soldering, welding, riveting, or the like, and are formed in the form of a U to provide a low self-inductance. The outlets are arranged so that the day is connected to the resistive sheet and the sheet is conductive. There is an insulating liner between the two sheets. The entire shunt is pressed against the steering wall, which is usually metallic, by its deflection side, through the insulating pad, with good thermal conductivity and high temperature resistance, thereby ensuring its cooling.
Zabezpečením dobrého intenzívneho kon-taktného chladenia bočníka sa umožní zní-žiť teplotu bočníka alebo jeho rozměry.Možno tiež zmenšiť rozměry zariadenia, zní-žit teplotu vnútri skrine, a tým zvýšiť, život-nost súčiastok. Vlastnou konštrukciou boč-níka z dvoch častí sa šetří drahý odporovýmateriál a vývin tepla sa sústreduje na dob-ře chladenú stranu bočníka.By ensuring a good intensive contact cooling of the shunt, it is possible to reduce the shunt temperature or its dimensions. It is also possible to reduce the dimensions of the device, to reduce the temperature inside the cabinet and thus to increase the life of the components. Owing to the design of the two-part sidewall, the expensive resistance material is saved and the heat generation is concentrated on a well-cooled shunt side.
Na pripojenom obrázku je znázorněný pří-klad prevedenia bočníka v půdoryse a ná-ryse.The attached figure shows an exemplary embodiment of the shunt in plan and elevation.
Bočník je vytvořený z plochého vodivéhopásu 1 a plochého odporového pásu 2, kto-ré sú vzájomne spojené v mieste 3. Medzipásmi je izolačná vložka 4. Takto vytvoře-ný bočník je upevněný cez izolačnú tepel-ne dobré vodivú podložku S na chladiacudošku 6. Merací vývod je usporiadaný s vý-výhodou koaxiálně 7.The shunt is formed from a flat conductive band 1 and a flat resistive band 2, which are connected to each other at the location 3. The insulator insert 4 is an intermediate layer. The shelf formed in this way is fastened via an insulating thermal conductive pad S to the cooling tube. the outlet is preferably arranged coaxially 7.
Funkcia bočníka spočívá v tom. že pripřechode prúdu cez bočník sa na ňom vy-tvoří úbytok napatia, ktorý je v důsledkunízkej indukčnosti bočníka priamo úměrnýprúdu i pri jeho rýchlych změnách. Úbytoknapatia na bočníku sa využívá na meranie,signálizáciu a riadenie prúdu najmá v ty-ristorových meničoch. 203302The shunt function is that. that the current flow through the shunt is caused by a voltage drop that is directly proportional to the current due to the low shunt inductance, even when it changes rapidly. Shunt loss is used for measurement, signaling and current control, especially in thyristor converters. 203302
