Description
Likeretteranlegg for store strømstyrker. Rectifier system for large currents.
Oppfinnelsen angår et likeretteranlegg som er bestemt for store strømstyrker og særlig tenkt anvendt for strømforsyning av anlegg med elektrokjemiske bad, og som arbeider enten med utladningsbeholdere som strømventiler eller med halvlederventiler, særlig på basis av en halvleder av germanium, silicium eller et annet halvleder-materiale med p-n-overgang og lignende belastbarhet. Slike anlegg arbeider for det meste med store strømstyrker og forholdsvis lav spenning, dvs. at likeret-terkoblingens ventilstrekninger er påkjent forholdsvis sterkt med strøm; men forholdsvis svakt med spenning. Med sikte på å oppnå en god virkningsgrad og en høy effektfaktor er det ønskelig å bygge slike anlegg med liten tapsmotstand og liten spredningsrektans. Ved slike likeretteranlegg byr det på særlige fordeler å anvende en trefase-transformator med trebenet kjerne for matningen og å anordne en sugekvelespole. The invention relates to a rectifier system which is intended for large currents and is particularly intended to be used for the power supply of systems with electrochemical baths, and which works either with discharge containers such as current valves or with semiconductor valves, in particular on the basis of a semiconductor made of germanium, silicon or another semiconductor material with p-n junction and similar loadability. Such installations mostly work with large currents and relatively low voltage, i.e. that the valve sections of the rectifier connection are loaded relatively strongly with current; but relatively weak with tension. With a view to achieving a good degree of efficiency and a high power factor, it is desirable to build such facilities with low loss resistance and low dispersion rectiactivity. In such rectifier systems, it offers special advantages to use a three-phase transformer with a three-legged core for the supply and to arrange a suction choke coil.
Ifølge oppfinnelsen kan et slikt likeretteranlegg for store strømstyrker forbedres ved at transformatoren utføres med en lavspenningsvikling hvor hver fase er delt opp i tofase-viklinger og hver slik tofase-vikling sammen med de tilhørende ventiler danner en to-veis likeretterkobling, samt at transformator og sugekvelespole er utført med separate viklinger, men felles jernkjerne, idet der er anordnet en jernkjerne med fire vinduer, hvor de tre ved siden av hinannen liggende ben som danner to av disse vinduer, bærer transformatorviklingene, mens de tre ben som danner de to øvrige vinduer, bærer sugekvelespolens vikling. According to the invention, such a rectifier system for large currents can be improved by making the transformer with a low-voltage winding where each phase is divided into two-phase windings and each such two-phase winding together with the associated valves form a two-way rectifier connection, and that the transformer and suction choke coil is made with separate windings, but a common iron core, as an iron core with four windows is arranged, where the three adjacent legs that form two of these windows carry the transformer windings, while the three legs that form the other two windows, carries the suction choke coil winding.
Det byr på særlige fordeler å utføre koblingsforbindelsene som korte motstands- og induksjons-fattige skinner, noe som lettes ved anordningen av viklingene nær hverandre på den felles kjerne. It offers particular advantages to make the connection connections as short resistance- and induction-poor rails, which is facilitated by the arrangement of the windings close to each other on the common core.
Oppfinnelsen kan brukes i forbindelse med en anvendelse av utladningsbeholdere som elektriske ventiler, men er i første rek-ke tenkt anvendt for anlegg med elektriske ventiler på basis av en halvleder av, eller av lignende art som, germanium eller silicium, som er istand til å føre store strøm-styrker ved spesifikt høy belastning av pn-overgangen. Slike ventiler kan på grunn av sitt lille plassbehov også anordnes nær transformatorviklingene. I denne forbindelse kan der også anvendes flere slike halvlederelementer, innbyrdes parallell-koblet, pr. ventilanordning. The invention can be used in connection with the use of discharge containers as electric valves, but is primarily intended to be used for installations with electric valves based on a semiconductor made of, or of a similar type as, germanium or silicon, which is capable of carry large currents at a specifically high load of the pn junction. Due to their small space requirements, such valves can also be arranged close to the transformer windings. In this connection, several such semiconductor elements can also be used, interconnected in parallel, per valve device.
Hele anordningen bestående av transformator, sugekvelespole og ventiler, kan anbringes i en felles beholder. The entire device, consisting of transformer, suction choke coil and valves, can be placed in a common container.
Tegningen anskueliggjør et utførelses-eksempel på en 3 x 2-fase-kobling som anvendes i henhold til oppfinnelsen. The drawing illustrates an embodiment of a 3 x 2-phase connection which is used according to the invention.
På fig. 1 betegner 1 transformatorens primærvikling. Den er utført i trekant-kobling og mates fra trefasenettet ved sine klemmer U, V, W. Transformatorens sekun-dærside er delt opp i et større antall av parallelle tofasede grenviklinger pr. fase. På det transformator-ben som bærer den del-primærvikling som ligger mellom til-slutningsklemmene U og V, er der således anordnet tofasede sekundærviklinger 2—5, som er tilsluttet hvert sitt par ventiler 6— 13. Transformatorens oppbygning på de øvrige ben er valgt på samme måte. 14 betegner sugekvelespolen, hvorav to og to viklinger, f. eks. 15 og 16, er anordnet på ett og ett ben av den felles jernkjerne. Mat-ningstransformatorens og sugekvelespolens jernkjerner er forenet til ett eneste jernlegeme. En slik oppbygning er f. eks. an-skueliggjort på fig. 2 og 3 i to til hinannen svarende riss. 17 betegner det lamellerte jernlegeme, som er felles for transformatoren og sugekvelespole-anordningen. Det er av den grunn utført med fire vinduer, så der fås tre ben 18—20 for transformatorviklingene og tre ben 21—23 for sugekvelespolens viklinger. Anordningen av transformatorens viklinger er for enkelhets skyld bare vist på benet 18 på fig. 2. 24 betegner f. eks. en vikling i transformatorens primær-del, mens de tilhørende sekundære faseviklinger er betegnet med 25—32. Således danner f. eks. viklingene 25 og 26 den to-fasede viklingsgren som er betegnet med 2 på fig. 1. In fig. 1 denotes 1 the transformer's primary winding. It is made in a triangular connection and is fed from the three-phase mains at its terminals U, V, W. The transformer's secondary side is divided into a larger number of parallel two-phase branch windings per phase. On the transformer leg which carries the partial primary winding which lies between the connection terminals U and V, there are thus arranged two-phase secondary windings 2—5, each of which is connected to a pair of valves 6—13. The structure of the transformer on the other legs has been chosen Similarly. 14 denotes the suction choke coil, of which two and two windings, e.g. 15 and 16, are arranged on each leg of the common iron core. The iron cores of the supply transformer and the suction choke coil are united into a single iron body. Such a structure is e.g. illustrated in fig. 2 and 3 in two to each other corresponding drawing. 17 denotes the laminated iron body, which is common to the transformer and the suction choke device. It is therefore designed with four windows, so there are three pins 18-20 for the transformer windings and three pins 21-23 for the suction choke coil windings. The arrangement of the windings of the transformer is, for the sake of simplicity, only shown on leg 18 in fig. 2. 24 denotes e.g. a winding in the primary part of the transformer, while the associated secondary phase windings are denoted by 25-32. Thus, e.g. windings 25 and 26 the two-phase winding branch which is denoted by 2 in fig. 1.
De øvrige sekundærviklinger er på til-svarende måte anordnet parvis oppdelt på de øvrige grener 3—5. Det ene ben 21 av den jernkjerne som den trefasede suge-kvelespoles viklinger er anordnet på, bærer f. eks. de to viklinger 15 og 16 i sugekvele-spoleanordningen på fig. 1. Viklingene på sugekvelespolekjernens to andre ben 22 og 23 er ikke antydet særskilt. P og N betegner tilslutningene som strømretterens plus-skinne 33 resp. minus-skinne 34 er ført frem til. I grunnrisset på fig. 3 sees disse to ledningsskinner 33 og 34 påny. Samtidig er der skjematisk antydet hvorledes de i dette tilfelle benyttede halvlederventiler, hvorav den ene er vist og betegnet med 35, er anordnet i umiddelbar nærhet av transformatorviklingene, så det på denne måte er oppnådd en sammentrengt oppbygning med de angitte elektriske fortrinn. Den anord-ning som er vist på fig. 2 og 3, kan, som allerede anført, være anordnet sammen med transformatoren i en felles, f. eks. oljefylt, beholder. The other secondary windings are similarly arranged in pairs, divided into the other branches 3-5. One leg 21 of the iron core on which the windings of the three-phase suction choke coil are arranged carries, e.g. the two windings 15 and 16 in the suction choke coil arrangement in fig. 1. The windings on the two other legs 22 and 23 of the suction choke coil core are not indicated separately. P and N denote the connections as the rectifier's plus rail 33 and minus rail 34 is brought up to. In the ground plan in fig. 3 these two cable rails 33 and 34 are seen again. At the same time, it is indicated schematically how the semiconductor valves used in this case, one of which is shown and designated by 35, are arranged in the immediate vicinity of the transformer windings, so that in this way a compressed structure with the specified electrical advantages has been achieved. The device shown in fig. 2 and 3, can, as already stated, be arranged together with the transformer in a common, e.g. oil-filled, container.
