Viklingsbeskyttelse for spoler. Winding protection for coils.
Oppfinnelsen angår i det vesentlige The invention essentially relates to
slike elektriske spoler som forekommer i lavspenningsanlegg. I disse anlegg er det en betydelig fare for at overspenninger av atmosfærisk opprinnelse skal føre til over- such electric coils as occur in low-voltage systems.

Fig. la viser den ene utførelsesform i Fig. la shows one embodiment i
oppriss, mens fig. lb viser den i snitt. elevation, while fig. lb shows it in average.
Den annen utførelsesform er vist på liknende måte i oppriss i fig. 2a og i snitt i fig. 2b. I figurene er deler som ligner hverandre betegnet med samme henvis-ningstall. I figurene er det angitt at en spole 1 er festet på en jernkjerne 2, med vindu 3. Spolen er forsynt med en eneste vikling 4, som består av tynn tråd. Viklingen 4 har to ender hvorav den ytre i punktet 5 er forbundet med det ytre uttaket 6, mens den indre ende i punktet 8 er forbundet med det indre uttaket 9. Den spole som er vist i fig. la og lb er forsynt med et ytre bånd 7 som består av ledende materiale, samt et indre bånd 10, som likeledes består av ledende materiale. Det ytre bånd omslutter spolen og dets ender overlapper hverandre. Det indre bånd som omsluttes av spolen, er på samme måte utført slik at dets ender overlapper hverandre. Det ytre ledende bånd 7 er isolert mot kjernen ved hjelp av et isolasjonsmel-lomlegg 11, mens det er isolert mot spolen og mellom sine overlappende ender ved hjelp av isolasjonsmellomlegget 12. På liknende måte er det indre ledende bånd 10 isolert mot kjernen ved hjelp av isolasjonsmellomlegget 13, mens dets isolasjon mot spolen og mellom det ledende båndets ender utgjøres av isolasjonsmellomlegget 14. Av opprisset i fig. la, hvor en del av det overlappende metallbånd 7 er skåret bort fremgår det at den tynne viklingstråd 4 er forbundet med uttaket 6 på en sådan måte at vikling.sstrømmen ikke eller bare for en uvesentlig del flyter gjennom det beskyttende bånd 7. The second embodiment is shown in a similar way in elevation in fig. 2a and in section in fig. 2b. In the figures, parts that are similar to each other are designated with the same reference number. In the figures, it is indicated that a coil 1 is attached to an iron core 2, with a window 3. The coil is provided with a single winding 4, which consists of thin wire. The winding 4 has two ends, of which the outer end at point 5 is connected to the outer outlet 6, while the inner end at point 8 is connected to the inner outlet 9. The coil shown in fig. la and lb are provided with an outer band 7 which consists of conductive material, as well as an inner band 10, which likewise consists of conductive material. The outer band encloses the coil and its ends overlap each other. The inner band enclosed by the coil is similarly designed so that its ends overlap each other. The outer conductive strip 7 is insulated against the core by means of an insulating spacer 11, while it is insulated against the coil and between its overlapping ends by means of the insulating spacer 12. Similarly, the inner conductive strip 10 is insulated against the core by means of the insulation spacer 13, while its insulation against the coil and between the ends of the conductive tape is constituted by the insulation spacer 14. From the outline in fig. 1a, where part of the overlapping metal band 7 has been cut away, it appears that the thin winding wire 4 is connected to the outlet 6 in such a way that the winding current does not flow through the protective band 7 or only to an insignificant part.
Den beskyttende virkning av de ledende bånd 7 og 10 fremgår av følgende: Når f. eks. en overspenning treffer spolen gjennom uttaket 6 vil det, under forutsetning av at den dielektriske styrke av isolasjonen 11 er lav nok skje et overslag mellom det ledende bånd 7 og den ytre del av kjernen 2. Båndet 7 er nemlig svakere isolert mot kjernen enn viklingstråden 4 i forhold til kjernen 2. Ved overslaget vil ganske visst isolasjonsmellomlegget 11 skades. Det ødelegges imidlertid i regelen ikke, men er tilstrekkelig sterkt til å virke isolerende når overspenningen er passert og bare den normale driftsspenningen ligger på spolen. Det ledende bånd oppviser kanskje en brannskade etter overslaget. Da båndet har et betydelig større flateinnhold enn den tynne viklingstråd 4 eller er ut-ført av materiale med høyere styrke mot avsmeltning, vil det ikke ødelegges men er i stand til å danne fotpunktet for nye over-slagsgnister ved ytterligere overspenninger til kjernen og således beholde sin beskyttende virkning. Selv om et helt parti av det ledende bånd skulle smelte i stykker ved gjentatte overslag, beholder spoleviklingen sin rette funksjon da båndet 7 ikke, eller bare for en uvesentlig del, gjennomflytes av viklingens normale strøm. Ved at de overlappende ender av båndet 7 er isolert fra hverandre ved hjelp av det indre isolasjonsmellomlegget 12, danner det ikke noen kortsluttet vinding og på-virker således ikke viklingens magnetiske felt. Det er derfor mulig å legge båndet 7 på en ferdigviklet spole uten at spolens felt undergår noen vesentlig endring. På samme måte fungerer det indre ledende bånd 10 ved overspenninger, som kommer inn på den indre ende 8 av spoleviklingen gjennom uttaket 9. Isolasjonen av båndet 10 mot den indre kjerne 2 er svakere enn vikling.strådens isolasjon og et eventuelt overslag til denne kjernedel vil således finne sted fra båndet 10. Styrken av dette bånd mot avsmelting er større enn viklingstrådens og gjentatte overslag klarer ikke å nedsette båndets beskyttende virkning i særlig grad. Heller ikke dette bånd danner en kortsluttet vinding takket være isolasjonsmellomlegget 14. The protective effect of the conductive bands 7 and 10 is evident from the following: When e.g. an overvoltage hits the coil through the outlet 6, provided that the dielectric strength of the insulation 11 is low enough, a flashover will occur between the conductive band 7 and the outer part of the core 2. Namely, the band 7 is more poorly insulated against the core than the winding wire 4 in relation to the core 2. The insulation spacer 11 will certainly be damaged during the impact. However, as a rule, it is not destroyed, but is sufficiently strong to act as an insulator when the overvoltage has passed and only the normal operating voltage is on the coil. The conductive tape may show a burn after the impact. As the tape has a significantly greater surface area than the thin winding wire 4 or is made of material with a higher strength against melting, it will not be destroyed but is able to form the footing point for new flashover sparks in the event of further overvoltages to the core and thus retain its protective effect. Even if a whole section of the conductive tape were to melt into pieces during repeated overturning, the coil winding retains its proper function as the tape 7 is not, or only to an insignificant part, flowed through by the winding's normal current. As the overlapping ends of the tape 7 are isolated from each other by means of the inner insulation spacer 12, it does not form a short-circuited winding and thus does not affect the winding's magnetic field. It is therefore possible to lay the band 7 on a pre-wound coil without the coil's field undergoing any significant change. In the same way, the inner conductive band 10 functions in case of overvoltages, which enter the inner end 8 of the coil winding through the outlet 9. The insulation of the band 10 against the inner core 2 is weaker than the winding. The insulation of the wire and any overshoot to this core part will thus taking place from the band 10. The strength of this band against melting is greater than that of the winding wire and repeated overshoots do not manage to reduce the protective effect of the band to any particular extent. This band also does not form a short-circuited winding thanks to the insulating spacer 14.
Den utførelsesform som er vist i fig. 2a og 2b skiller seg fra den som er vist i fig. la og lb, forsåvidt som de beskyttende elektrisk ledende deler her utgjøres av en forsterket vikling eller uttakstråd, som helt eller for den største del dekker de områder av spoleviklingen som er mest utsatt for overslag. Den forsterkede vikling eller den forsterkede uttakstråd 15 er da koblet i serie med den tynne viklingstråd 4 og gjennomflytes helt eller for en vesentlig del av denne viklings normale strøm. Til forskjell fra den anordning som er vist i fig. la og lb kan det herved i visse ugun-stige tilfeller oppstå avbrudd eller kort-slutning i viklingens strømkrets, hvis nemlig den forsterkede viklingen ved et meget kraftig overslag eller ved gjentatte overslag helt skulle smelte av på et eller annet sted. Takket være at den forsterkede tråd har så stor styrke mot avsmeltning er imidlertid denne fare liten. På den annen side byr denne anordning den fordel at de ledende deler virker som en del av viklingen og at de samtidig kan erstatte den uttakstråd som er vanlig ved spoler og som vanlig skjøtes til enden av den tynne viklingstråd for at viklingen lettere skal kunne forbindes med andre apparatdeler. Den forsterkede viklingen er i fig. 2 betegnet 15 og skiller seg fra kjente uttaksfor-sterkninger på den måte at den dels helt eller for den største del dekker det område av spoleviklingen som er mest utsatt for overslag dels ved at den har en svakere isolasjon i forhold til kjernen 2 enn viklingstråden 4. Selv den indre ende 8 av spoleviklingen skulle kunne sluttes til en liknende forsterket vikling eller uttakstråd. I fig. 2b er imidlertid de ledende The embodiment shown in fig. 2a and 2b differ from that shown in fig. la and lb, provided that the protective electrically conductive parts here are made up of a reinforced winding or take-out wire, which completely or for the most part covers the areas of the coil winding that are most exposed to flashover. The reinforced winding or the reinforced outlet wire 15 is then connected in series with the thin winding wire 4 and is completely or for a significant part of this winding's normal current flowed through. Unlike the device shown in fig. la and lb, in certain unfavorable cases interruptions or short-circuits in the current circuit of the winding may occur, if the reinforced winding were to completely melt off in one place or another in the event of a very strong overturn or repeated overturns. However, thanks to the fact that the reinforced wire has such great strength against melting, this danger is small. On the other hand, this device offers the advantage that the conductive parts act as part of the winding and that they can at the same time replace the take-out wire which is usual for coils and which is usually spliced to the end of the thin winding wire so that the winding can be more easily connected to other appliance parts. The reinforced winding is in fig. 2 denoted 15 and differs from known outlet reinforcements in that it partly completely or for the most part covers the area of the coil winding that is most exposed to flashover and partly in that it has a weaker insulation in relation to the core 2 than the winding wire 4 Even the inner end 8 of the coil winding should be able to be connected to a similar reinforced winding or tap wire. In fig. 2b, however, are the leading ones
