Description

L'invention est relative à un dispositif de gestion électronique pour chauffe-eau électrique à accumulation.The invention relates to a management device electronics for electric storage water heaters.

La régulation thermostatique et le déclenchement en sécurité de l'alimentation de la résistance de chauffage d'un chauffe-eau électrique à accumulation est en général assurée par un thermostat électromécanique. Ces thermostats électromécaniques de type connu se présentent généralement sous forme d'ensembles comprenant des sondes de température, à canne bimétallique, à disque ou à bulbe à dilatation de liquide agissant mécaniquement sur des contacts électriques de puissance.Thermostatic regulation and tripping in heating resistor supply security of an electric storage water heater is generally provided by an electromechanical thermostat. These thermostats electromechanical devices of known type generally arise in the form of assemblies comprising temperature, bimetallic rod, disc or bulb expansion of liquid acting mechanically on electrical power contacts.

Il est également habituel d'assurer la protection cathodique des cuves de chauffe-eau par un système d'anode à courant imposé, consistant à maintenir en permanence la circulation d'un courant électrique de protection produit par un générateur à courant continu entre une anode isolée en matériau noble et insensible à la corrosion et la cuve du chauffe-eau.It is also customary to provide protection cathodic water heater tanks by an anode system with impressed current, consisting in permanently maintaining the circulation of a product protection electric current by a DC generator between an isolated anode in noble material and insensitive to corrosion and the tank of the water heater.

Il est également avantageux d'alimenter électriquement la résistance du chauffe-eau en fonction des modulations tarifaires appliquées par la compagnie productrice d'électricité. A cet effet, on alimente généralement les chauffe-eau par des contacteurs multi-positions présentant généralement trois modes de fonctionnement : un mode de fonctionnement automatique, dans lequel la résistance du chauffe-eau est alimentée par pilotage au moyen d'un signal émis par la compagnie d'électricité pendant les périodes correspondant aux heures creuses ou au tarif de nuit; un mode de fonctionnement assurant la mise hors tension de la résistance du chauffe-eau; et un mode de fonctionnement en marche forcée pour assurer une alimentation permanente, par exemple en cas de manque d'eau chaude.It is also advantageous to supply electricity the resistance of the water heater according to the modulations tariffs applied by the producing company of electricity. For this purpose, we generally supply the water heater by multi-position contactors presenting generally three operating modes: a automatic operation, in which the resistance of the water heater is supplied by piloting by means of a signal issued by the electric company during the periods corresponding to off-peak hours or the night tariff; a operating mode ensuring that the resistance of the water heater; and a mode of operation in forced march to ensure a permanent supply, by example in case of lack of hot water.

Des contacteurs correspondants, appelés "contacteurs d'alimentation pour plages tarifaires", se présentent sous forme d'éléments modulaires électriques généralement fixés dans le tableau électrique général de l'installation, à une certaine distance du chauffe-eau.Corresponding contactors, called "contactors for price ranges ", are shown under generally modular electrical elements in the general electrical panel of the installation, at a certain distance from the water heater.
