Description

4§§ 236 Erfarenheten har visat, att konventionella polningsförfaranden är svåra att genomföra och dyrbara, att enstaka eller flera pol- ningsställenjfiätibrytes, varigenom den önskade likformiga potenti- alfördelningen vid glímskyddsbeläggningen går förlorad, och att glimskyddsbeläggningens verkan upphör. ' Ändamålet med uppfinningen är att ange en konstruktiv lös- nínå för P0lning av glimskyddsbeläggningen, vid vilken ett tekniskt misslyckande av ovan antytt slag undvikes, och vid vilken fram- ställningskostnaderna blir avsevärt sänkta i förhållande till ti- digare kända lösningar samt vid vilken en tillräckligt likformig potentialfördelning kan åstadkommas över hela glimskyddsbeläggning- en. 4§§ 236 Experience has shown that conventional polishing procedures are difficult to carry out and expensive, that single or more polishing points are broken, whereby the desired uniform potential distribution in the anti-slip coating is lost, and that the effect of the anti-glare coating ceases. The object of the invention is to provide a constructive solution for polishing the anti-glare coating, in which a technical failure of the kind indicated above is avoided, and in which the manufacturing costs are considerably reduced in relation to previously known solutions and in which a sufficient uniform potential distribution can be achieved over the entire glow protection coating.

Uppfinningen avser sålunda en anordning av ovan angivet slag, vid vilken enligt uppfinningen det ytterligare ledarsyste- met består av en band- eller trádformig metallisk ledare, t ex av nysilver, som endast täcker en del av den yta, som skall skyddas mot glimurladdningar, och är anordnad mellan glimskyddsbelägg- ningen och det isolerade ledarknippet.The invention thus relates to a device of the type indicated above, in which according to the invention the further conductor system consists of a strip-shaped or wire-shaped metallic conductor, for example of nickel silver, which covers only a part of the surface to be protected against glow discharges, and is arranged between the anti-glare coating and the insulated conductor bundle.

Enligt en ytterligare utföringsform av uppfinningen kan den metalliska ledaren bestå av motstàndsmaterial, t ex nysilver (ISO-beteckning CuNí18Zn20 enligt DIN 17663).According to a further embodiment of the invention, the metallic conductor may consist of resistive material, for example nickel silver (ISO designation CuNí18Zn20 according to DIN 17663).

Den band- eller trådformiga ledaren kan vara anordnad i ledarbanor i linjeform, strålform eller kurvform, antingen i enkla strängar eller i form av ett nätverk.The band-shaped or wire-shaped conductor can be arranged in conductor paths in line form, beam form or curve form, either in simple strands or in the form of a network.

Uppfinningen beskrives närmare nedan under hänvisning till bi- fogade ritning, som schematiskt visar inbyggnaden av polningsledar- systemet enligt en såsom exempel vald utföringsform.The invention is described in more detail below with reference to the accompanying drawing, which schematically shows the installation of the polarity conductor system according to an exemplary embodiment.

På ritningen betecknar 1 huvudisoleringen, 2 den halvledande glimskyddsbeläggningen och 3 polningsledarsystemet, som vid den visade utföríngsformen medelst ett polningsställe H är förbundet med kopparn i lindningen (ledaren 5). Ledaren 5 är försedd med en isolering 6, under det att hela ledarknippet 7 är försett med en knippesisolering 8 (kan även utelämnas). Glimskyddsbeläggningen 2 anbringas omedelbart över polningsledarsystemet, här ett litet band, så att den står i elektriskt ledande förbindning med detsamma.In the drawing, 1 denotes the main insulation, 2 the semiconducting glow protection coating and 3 the polarity conductor system, which in the embodiment shown is connected to the copper in the winding by means of a polarity point H (conductor 5). The conductor 5 is provided with an insulation 6, while the entire conductor bundle 7 is provided with a bundle insulation 8 (can also be omitted). The anti-glare coating 2 is applied immediately over the polar conductor system, here a small band, so that it is in electrically conductive connection with it.

På detta sätt utjämnas potentialfördelningen över hela glimskydds- beläggningen i önskad utsträckning.In this way, the potential distribution over the entire glow protection coating is evened out to the desired extent.
