Definitions

  • the invention relates to a mains voltage insulation according to the first part of patent claim 1.
  • the object of the invention is therefore to be able to operate metallic sensors below the glass ceramic cooktop in the hot area thereof without having to work with protective low voltage.
  • FIG. 1 an arrangement representing the situation according to FIG. 1 as an equivalent circuit.
  • This is the dielectric sequence in which the sensor 2 is constructed. Electrostatically, the sensor represents a capacitive series circuit that isolates the mains voltage and is dimensioned in such a way that it provides protection against mains voltage contact.
  • Mikanit® is used as the insulation and dielectric material, the arrangement-related dielectric sequence then being carried out by a micanite layer with a subsequent glass ceramic layer and an identical micanite layer.
  • This sensor arrangement acts as a capacitive and temperature-dependent indicator as a result of changes in capacitance due to materials on the glass ceramic or via the loss factor delta as a function of the time of the glass ceramic.
  • the sensor created in this way is at the same time as an insulation layer against the metalization 2 from the mains voltage.

Claims (2)

  1. Isolation de la tension du réseau avec des détecteurs situés sous des plaques de cuisson en vitrocéramique, un détecteur métallique (2) étant disposé sous une plaque de cuisson en vitrocéramique (1) dans ou en dehors de la zone chaude de la plaque de cuisson en vitrocéramique (1) conditionnée par un corps de chauffe rayonnant (4), caractérisée en ce que le détecteur (2) peut fonctionner à un point de fonctionnement d'une fréquence supérieure à celle du régime normal, et en ce que le détecteur (2) est réalisé en tant que couplage capacitif en série isolant de la tension du réseau, qui est dimensionné pour assurer une protection de contact contre la tension du réseau, de telle sorte que le couplage capacitif en série conditionné par la disposition soit constitué de trois diélectriques qui sont entourés de métallisations.
  2. Isolation de la tension du réseau selon la revendication 1, caractérisée en ce que les diélectriques sont constitués de moyens d'isolation (3) et de la plaque de cuisson en vitrocéramique (1).
