Skandinavisk Patent Bureau v/Frode Larsen._ , (54) Filterdrossel for høje elektriske spændinger og store effekter.Scandinavian Patent Bureau v. Frode Larsen._, (54) Filter choke for high electrical voltages and large effects.
Opfindelsen angår en filterdrossel for høje elektriske spændinger og store effekter og med lineær karakteristik og med en sammen med en trinomskifter i en med isolervæske fyldt tank anbragt vikL ling, hvor lastomskifteren og trinvælgeren er indbygget véd siden af hinanden i en flad, opefter med et dæksel lukket tank.BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a filter throttle for high electrical voltages and large effects and with linear characteristics and with a coil mounted in a tank filled with insulating liquid, the load switch and the step selector being side by side in a flat, upwards with a cover. closed tank.
Viklingerne af filterdrosler for store effekter indbygges sædvanligvis i med transformatorolie fyldte tanke. Herved skal viklingerne på den ene side isoleres for den fulde prøvespænding mød den jor- 2 142095 dede tant og på den anden side skal tanken og andre i nærheden anbragte metalliske konstruktionsdele ved en mellem dem og viklingerne anbragte kappe af lamelleret transformatorplade være afskærmet fra viklingens magnetfelt for at holde de optrædende ekstratab så små som muligt.The windings of filter thrusters for large effects are usually built into tanks filled with transformer oil. In this way, the windings must be insulated on the one hand for the full test voltage to meet the earthed aunt and on the other hand the tank and other nearby metallic structural parts at a sheath of laminated transformer plate arranged between them and the windings must be shielded from the magnetic field of the winding. to keep the occurring extra losses as small as possible.
Når sådanne arrangementer af viklingerne for drosselspoler anvendes som filterdrosler for i forhold til netfrekvensen højere harmoniske svingninger af spænding og strøm, så er en så vidt muligt absolut lineær karakteristik nødvendig. Af denne grund må kappen af lamelleret transformatorplade ikke udnyttes magnetisk indtil mætning. Som følge af dette krav fås en forholdsvis lav tilladelig induktion for den til skærmning tjenende kappe, så at dens fremstilling kræver en betydelig indsats af materiale og fremstillingstid, så snart der forlanges en lineær karakteristik for filterdroslen.When such arrangements of the coils for throttle coils are used as filter throttles for higher harmonic fluctuations of voltage and current in relation to the grid frequency, then, as far as possible, an absolutely linear characteristic is necessary. For this reason, the sheath of laminated transformer plate must not be used magnetically until saturation. As a result of this requirement, a relatively low allowable induction is obtained for the shielding sheath, so that its manufacture requires considerable effort of material and production time as soon as a linear characteristic of the filter throttle is required.
Fra engelsk patentskrift nr. 1 027 151 er det kendt at anbringe en drosselspole i et porcelænshus, men ved en sådan anbringelse vil der dannes udefinerbare, af den øjeblikkelige belastning afhængige magnetfelt- og fluxændringer.It is known from English Patent No. 1,027,151 to place a choke coil in a porcelain housing, but such an arrangement will produce undefinable, magnetic field and flux changes dependent on the instantaneous load.
Det er derfor formålet med opfindelsen at anvise en filterdrossel af den angivne art med lineær karakteristik, hvor magnetisk afskærmning kan undværes, og derved såvel den til fremstillingen nødvendige indsats af materiale og arbejde som samtidig totaldimensionerne af filterdroslen holdes så små som muligt.It is therefore the object of the invention to provide a filter throttle of the specified type with a linear characteristic where magnetic shielding can be avoided, thereby keeping as little as possible both the material and work required for manufacture and the overall dimensions of the filter throttle.
Ifølge opfindelsen opnås dette ved, at en over trinvælgeren på dækselet anbragt højspændingsgennemføring af fast isoleringsmateriale omfatter den magnetisk ikke afskærmede, på isolerringe hvilende vikling, hvorhos af tanken og højspændingsgennemføringen indesluttede inderrum er forbundet med hinanden over en med højspændingsgennemføringen koaksial udsparing i dækselet.According to the invention, this is accomplished by a high-voltage solid insulation material placed above the cover selector on the cover comprises the magnetically unshielded winding resting on insulating rings, the inner space of which is enclosed by the tank and the high-voltage feed through a coaxial cut-out of the high-voltage feed.
Udførelsen af en filterdrossel ifølge opfindelsen muliggør besparelse af både en magnetisk afskærmning og en elektrisk hovedisolation af viklingen. Desuden opnås en spændingsstyring langs overfladen af højspændingsgennemføringen, der ellers kun kunne opnås ved en kompliceret og dyr gennemføring, især en kondensator-gennemføring.The design of a filter choke according to the invention enables saving of both a magnetic shield and an electrical main insulation of the winding. In addition, a voltage control is obtained along the surface of the high voltage lead-through, which otherwise could only be achieved by a complicated and expensive feed-through, especially a capacitor feed-through.
Fordelagtige udførelsesformer ifølge opfindelsen består i, at den flade tank er udført med oval bund og dæksel, og at trinvælgeren, viklingen og højspændingsgennemføringen er anbragt koaksi-alt med hinanden ved den ene ende af tanken på en sådan måde, at 3 142095 mellem viklingen og trinvælgeren nødvendige ledninger er ført gennem udsparingen i tankens dæksel. Derved er der uden for den modsat trinvælgeren beliggende, lastomskifteren optagende ende af tanken anbragt en trinomskiftermekanisme.Advantageous embodiments of the invention consist in that the flat tank is provided with an oval base and cover, and that the step selector, winding and high voltage feed-through are coaxially arranged at one end of the tank in such a way that between the winding and the The necessary wiring steps are passed through the recess in the tank cover. Thereby, outside the step selector, the load switch receiving end of the tank is arranged a step switch mechanism.
I andre fordelagtige udførelsesformer ifølge opfindelsen er den øvre ende af viklingen forbundet direkte med indersiden af kiemho-vedet på højspændingsgennemføringen, og den nedre ende af viklingen': er udført som trinvikling.In other advantageous embodiments of the invention, the upper end of the winding is connected directly to the inside of the germwood of the high voltage feedthrough, and the lower end of the winding is designed as a step winding.
På tegningen er der vist en udførelsesform for en filterdrossel ifølge opfindelsen, idet fig. 1 viser filterdrosselen i snit, og fig. 2 samme set fra oven.In the drawing, an embodiment of a filter throttle according to the invention is shown, fig. 1 is a sectional view of the filter choke, and FIG. 2 same from above.
I en tank 4 med oval bund 8 og ligeledes ovalt dæksel 9 er en trinvælger 5 og en lastomskifter 6 indbygget ved siden af hinanden. Akserne af trinvælgeren 5 og lastomskifteren 6 er vinkelrette eller lodrette over bunden 8, parallele med hinanden og er beliggende i hver sin ende af tanken 4. Over trinvælgeren 5 er der i dækselet 9 koaksialt med trinvælgeren 5 udformet en udsparing, der er dækket af en ligeledes koaksialt dermed anbragt, fortrinsvis af porcelæn fremstillet højspændingsgennemføring 2. Koncentrisk i højspændingsgennemføringen 2 og over udsparingen i dækselet 9 er der på isoler- . -ringe 10 anbragt en af skivespoler opbygget og som rørvikling udført kerneløs vikling 1. På højspændingsgennemføringen 2 er der anbragt et klemhoved 3* der er elektrisk forbundet med den øverste ende af viklingen 1.In a tank 4 with oval bottom 8 and also oval cover 9, a step selector 5 and a load switch 6 are incorporated side by side. The axes of the step selector 5 and the load switch 6 are perpendicular or vertical above the bottom 8, parallel to each other and located at each end of the tank 4. Above the step selector 5, a recess is formed coaxially with the step selector 5, which is covered by a also coaxially disposed therewith, preferably made of porcelain, high voltage feed-through 2. Concentric in the high-voltage feed-through 2 and above the recess in the cover 9, there is insulated. rings 10 arranged one of disc coils constructed and tubeless winding constructed as a tube winding 1. On the high voltage lead 2, a clamping head 3 * is electrically connected to the upper end of the winding 1.
De af tanken 1 og højspændingsgennemføringen 2 dannede inderrua er fuldstændigt fyldt med transformatorolie, der efter opvarmning suges bort gennem et op over viklingen 1 ragende isoler-rør 7 og en bortsugningsledning 12 fra den øverste del af højspændingsvik- , lingen 2 og efter tilbagekøling igen føres tilbage til tanken gennem en tilslutningsstuds 11.The inner shell formed by the tank 1 and the high voltage feed 2 is completely filled with transformer oil which, after heating, is sucked away through an insulating pipe 7 extending over the winding 1 and a suction line 12 from the upper part of the high voltage winding 2 and after reflux. back to the tank through a connector 11.
Yed siden af højspændingsgennemføringen 2 ved den anden ende af tanken 4 er der over lastomskifteren 6 anbragt en gasdom 13* der optager eventuelt ved omskiftningen opstående gas og derved forhindrer dennes Indtrængen i viklingsrummet. På ydersiden af tanken 4 ved siden af lastomskifteren 6 er der på eller i tankvæggen anbragt en trinomskifterdrivmekanisme 14 og en lavspændingsklemme 15.Next to the high-voltage feed-through 2 at the other end of the tank 4, a gas dome 13 * is placed above the load switch 6 which absorbs any gas arising from the switch and thereby prevents its entry into the winding room. On the outside of the tank 4 next to the load switch 6, there is arranged on or in the tank wall a step-switch drive mechanism 14 and a low voltage terminal 15.
Klemhovedet 3 er udadtil elektrisk forbundet med en ikke vist højspændingstilledning og indadtil, som allerede forklaret, med den øvre ende af viklingen 1. Ved opbygningen af viklingen 1 afThe terminal head 3 is electrically outwardly connected to a high voltage position not shown and inwardly, as already explained, to the upper end of the winding 1.
