Description
Drivsystem for eléktrisitetsmålere med trommelanker. Drive system for electricity meters with drum anchors.
Eléktrisitetsmålere med trommelanker Electricity meters with drum anchors
er først i den senere tid igjen trådt ster-kere i forgrunnen ved siden av målerne med skiveanker etter at det var lykkes ved tilnærmelsesvis sinusformet fordeling av de drivende flukser over ankeromkretsen å rydde tidligere foreliggende mangler av veien. I tidligere forslag er slike konstruk-sjoner beskrevet. Ved den hittil vanlige utførelsesform av trommelanker-målere er der benyttet en symmetrisk oppbygning av drivsystem-jernet med to spennings- og to strømspoler. Denne symmetriske anordning betinger likeoverfor skiveanker-målere et øket behov for kobber og jern og også for plass. Hertil kommer at til-gjengeligheten og anbringelsesmuligheten for reguleringsorganer blir sterkt vanske-liggjort; has only in recent times again stepped more strongly into the foreground next to the gauges with disk anchors after it had succeeded in clearing previously present deficiencies of the road by an approximately sinusoidal distribution of the driving fluxes over the anchor circumference. Such constructions have been described in previous proposals. In the hitherto common design of drum armature meters, a symmetrical construction of the drive system iron with two voltage and two current coils is used. This symmetrical arrangement requires an increased need for copper and iron, and also for space, directly opposite disc anchor gauges. In addition, the availability and placement of regulatory bodies is made very difficult;
Oppfinnelsen angår en elektrisitetsmåler med trommelanker, hvor stator jernet for å frembringe drivflukser som er fordelt sinusformet på ankeromkretsen, består av fire polsko som med sine polflater omslutter ankeret symmetrisk og nesten fullstendig. Hensikten med oppfinnelsen er å rydde de anførte mangler av veien, og dette opnas ved at der til å frembringe spenningsdrivfluksen bare er anordnet én spenningsspole, som er anordnet på et åk jern som danner magnetisk ledende forbindelse mellom to av drivsystemets fire polsko, mens strømspolene befinner seg på hvert sitt åk, og disse åk hver for seg danner magnetisk ledende forbindelse mellom én av de to nevnte polsko og én av de to øvrige. Hensiktsmessig er der mellom de polsko som ligger overfor spenningsspolen regnet i forhold til trommelankeret, anordnet en dreiemoment-regulator. Mellom polskoene på spenningssiden er der anordnet en magnetisk shunt. The invention relates to an electricity meter with a drum armature, where the stator iron to produce driving fluxes which are distributed sinusoidally on the armature circumference, consists of four pole shoes which with their pole surfaces surround the armature symmetrically and almost completely. The purpose of the invention is to clear the listed shortcomings out of the way, and this is achieved by the fact that only one voltage coil is arranged to produce the voltage drive flux, which is arranged on an iron yoke that forms a magnetically conductive connection between two of the drive system's four pole shoes, while the current coils are located themselves on their respective yokes, and these yokes individually form a magnetically conductive connection between one of the two aforementioned pole shoes and one of the other two. Appropriately, a torque regulator is arranged between the pole shoes which lie opposite the tension coil in relation to the drum armature. A magnetic shunt is arranged between the pole shoes on the voltage side.
På tegningen er vist et utførelses-eksempel på drivsystemet ifølge oppfinnelsen. The drawing shows an embodiment of the drive system according to the invention.
Stator jer net består av de fire polsko 1, 2, 3, 4 som med sine polflater nesten fullstendig omslutter en indre kjerne 5. I luftspalten mellom polflatene og den indre kjerne er trommelankeret 6 anordnet. Polskoene 1 og 3 er forbundet ved strømfluks-jernet 8, og polskoene 2 og 4 er forbundet ved strømfluksjernet 7. Strømfluksjernene bærer strømspolene henholdsvis 8' og 7'. Polskoene 1 og 2 overspennes av spennings-fluksjernet 9, som bærer spenningsspolen 9'. Mellom de to polsko 1 og 2 er der dessuten anordnet en magnetisk shunt 10. The stator mesh consists of the four pole shoes 1, 2, 3, 4, which with their pole surfaces almost completely enclose an inner core 5. In the air gap between the pole surfaces and the inner core, the drum armature 6 is arranged. The pole shoes 1 and 3 are connected by the current flux iron 8, and the pole shoes 2 and 4 are connected by the current flux iron 7. The current flux irons carry the current coils 8' and 7' respectively. The pole shoes 1 and 2 are overstressed by the voltage-flux iron 9, which carries the voltage coil 9'. A magnetic shunt 10 is also arranged between the two pole shoes 1 and 2.
Rett overfor spenningsspolen, regnet i forhold til ankeret, er der mellom polskoene 3 og 4 anbragt en dreiemomentregulator Directly opposite the tension coil, calculated in relation to the armature, a torque regulator is placed between pole shoes 3 and 4
11. De prikkede linjer viser forløpet av 11. The dotted lines show the progress of
spenningsdrivfluksen som frembringes av spenningsspolen. the voltage driving flux produced by the voltage coil.
Ved drivsystemet ifølge oppfinnelsen må der i det eneste spenningsfluks-jern frembringes en magnetfluks som leverer samme drivende fluks som de to spenningsfluks-jern ved en trommelankermåler med to spenningsspoler, dvs. magnetfluksen må fordobles. For å oppnå dette har spenningsfluks-jernet, når man legger samme maksimale induksjon til grunn, det dob-belte tverrsnitt likeoverfor spenningsfluks-jernet ved de tidligere utførelsesformer. Ved den nye anordning kan der derfor riktignok ikke foretas noen minskning av jernets vekt, men der oppnås en vesentlig minskning av kobbervekten, da der iste-denfor to seriekoblede spenningsspoler nu benyttes én spole, som under bibehold av sitt vindingstall er koblet til full spenning, og da trådtverrsnittet kan holdes uforan-dret på grunn av at den opptatte magneti-seringsstrøm blir den samme. Ved trom-melankermåleren med bare én spenningsspole inntrer der dessuten en minskning av kobbertapene som følge av den reduserte virksomme motstand av spenningsspolen. Den plass som hittil var nødvndig for det annet spenningsfluks-jern og den annen spenningsspole såvel som for den annen magnetiske shunt, blir ved anordningen ifølge oppfinnelsen fri og blir disponibel for anbringelse av en dreiemomentregulator. Med hensyn til målerens måle-egen-skaper byr oppbygningen av måleren ifølge oppfinnelsen dessuten på en vesentlig for-del forsåvidt som strømdrivfluksens jern-vei her blir formagnetisert i betydelig grad ved hjelp av den del av spenningsdrivfluksen som er ført over strømfluks-jernet, og der dermed undgås permeabilitets-inn-flydelser i området for liten belastning. Dette er av vesentlig betydning med hensyn til lastekurveforløpet, særlig ved presi-sjonsmålere. With the drive system according to the invention, a magnetic flux must be produced in the only voltage flux iron which supplies the same driving flux as the two voltage flux irons in a drum armature meter with two voltage coils, i.e. the magnetic flux must be doubled. To achieve this, the voltage flux iron, when one assumes the same maximum induction, has the double cross-section directly opposite the voltage flux iron in the previous embodiments. With the new arrangement, therefore, it is true that no reduction in the weight of the iron can be made, but a significant reduction in the copper weight is achieved, since instead of two series-connected voltage coils, one coil is now used, which, while maintaining its number of turns, is connected to full voltage, and since the wire cross-section can be kept unchanged due to the fact that the applied magnetizing current remains the same. In the case of the drum armature meter with only one voltage coil, there is also a reduction in the copper losses as a result of the reduced effective resistance of the voltage coil. The space which until now was necessary for the second voltage flux iron and the second voltage coil as well as for the second magnetic shunt is freed by the device according to the invention and becomes available for placing a torque regulator. With regard to the measuring properties of the meter, the structure of the meter according to the invention also offers a significant advantage insofar as the iron path of the current drive flux is here pre-magnetized to a significant extent by means of the part of the voltage drive flux which is carried over the current flux iron, and where permeability inflows in the area of low load are thus avoided. This is of significant importance with regard to the course of the load curve, particularly with precision gauges.
