Description

10 15 20 25 30 -1- 10 15 20 25 30 -1-

La présente invention concerne une boîte de résistances temporisées pour la vérification des contrôleurs permanents d'isolement (ci-après CPI ). The present invention relates to a box of timed resistors for the verification of permanent insulation controllers (hereinafter CPI).

Pour l'instant la vérification des CPI est effectuée par des résistances de faibles valeurs non temporisées et non protégées par Contrôle Thermique Négatif (ci-après CTN ). Ce manque actuel dans la vérification des CPI entraîne lors de sur-chauffe la destruction des résistances. For the moment the verification of the CPI is carried out by resistances of small values not timed and not protected by Negative Thermal Control (hereinafter CTN). This current lack of verification of CPI leads to over-heating the destruction of resistances.

Le dispositif selon l'invention permet de remédier à cet inconvénient. Le dispositif est composé d'un circuit imprimé reliant tous les composants dont les résistances, à l'interface (2) (10 bornes noires, 1 jaune et verte, et les deux leds). En intégrant un circuit intégré avec une CTN, cela permet la temporisation de la valeur ohmique entre les bornes (3) et (4) et la coupure du dispositif avant la sur-chauffe. Cette association de la temporisation et de la CTN permet une bonne protection pour les résistances de puissances. Suivant la démarche de vérification des CPI : -la borne vert/jaune marquée C (3) met le montage sous tension dès qu'une fiche banane de 4mm du cordon allant sur le CPI à contrôler est introduite sortie S1. - la led verte (5) s'éclaire dès que la fiche est introduite. -une led rouge (6) s'éclaire dès qu'une fiche banane 4mm de l'autre cordon est introduite sortie S2, indiquant ainsi que la temporisation est en cours. Si la led rouge clignote cela signifie que la temporisation est coupée. - la réalisation du circuit imprimé (7) reliant les bornes à contacts et les composants dont le circuit intégré IC2 (8) pour la programmation de la temporisation. - une temporisation de 6 secondes s'effectue pour les 3 valeurs suivantes : 5005 ,11c ,2kS . - une temporisation de 15 secondes s'effectue pour les 7 autres valeurs suivantes : 5kQ, 10ko, 20ko, 501Ç!2, 1001c n, 150kS, 197ko. - la protection thermique (9) est effectuée par le contrôle thermique négatif. The device according to the invention overcomes this disadvantage. The device is composed of a printed circuit connecting all the components including the resistors, to the interface (2) (10 black terminals, 1 yellow and green, and the two leds). By integrating an integrated circuit with a CTN, this allows the delay of the ohmic value between the terminals (3) and (4) and the breaking of the device before overheating. This combination of timing and CTN provides good protection for power resistors. In accordance with the inspection procedure of the CPIs: -the green / yellow terminal marked C (3) puts the assembly under tension as soon as a 4mm banana plug of the cord going to the CPI to be checked is introduced at output S1. - the green led (5) lights up as soon as the plug is inserted. - A red led (6) lights up as soon as a 4mm banana plug of the other cord is inserted output S2, indicating that the timer is running. If the red led flashes, the timer is off. - The realization of the printed circuit (7) connecting the contact terminals and the components including the IC2 integrated circuit (8) for programming the timer. - a delay of 6 seconds is carried out for the following 3 values: 5005, 11c, 2kS. a delay of 15 seconds is carried out for the following 7 other values: 5kΩ, 10kΩ, 20kΩ, 50kΩ, 2k, 100k, 150kS, 197k. - The thermal protection (9) is performed by the negative thermal control.

Le synoptique indique le branchement électrique de la boite de résistances avec le CPI . 2929014 -2- Attached diagram and block diagram illustrate the invention: The diagram indicates the operation of the electronic assembly. The synoptic indicates the electrical connection of the resistance box with the CPI. 2929014 -2-

En référence à ses dessins, sur le couvercle (2) de la boite de résistances (l) se situe toutes les interfaces (les dix bornes noires, la led rouge et la verte, la bornes vert/jaune) nécessaire à la vérification des CPI. Son utilisation s'effectue ainsi : Après introduction d'une fiche banane de 4mm du cordon allant sur le CPI à contrôler dans la borne vert/jaune marquée C (3), la led verte (5) s'éclaire et indique que le montage est sous tension. Puis, après introduction d'une fiche banane de 4mm de l'autre cordon allant sur le CPI à contrôler dans une des dix bornes noires (4), ce nombre permet à l'utilisateur de choisir la valeur de résistance, la led rouge (6) s'éclaire et indique que la temporisation est en cours. With reference to his drawings, on the cover (2) of the resistor box (l) are all the interfaces (the ten black terminals, the red led and the green, the green / yellow terminals) necessary for the verification of the CPIs. . Its use is as follows: After introduction of a 4mm banana plug from the cord going to the CPI to be checked in the green / yellow terminal marked C (3), the green led (5) lights up and indicates that the assembly is on. Then, after introducing a 4mm banana plug from the other cord going to the CPI to be controlled in one of the ten black terminals (4), this number allows the user to choose the resistance value, the red LED ( 6) lights up and indicates that the timer is running.

La réalisation du schéma se fait par un circuit imprimé (7) qui assemble les composants avec les bornes (3et4) et les leds (5et6) dans le boîtier (1). 15 Le temps de la temporisation peut être modifié sans changer le schéma car il y a juste la programmation du circuit intégré IC2 (8) pour changer la durée. La protection des résistances est réalisée par le fonctionnement de la temporisation des résistances (puissance choisit suivant la valeur ohmique) et de la CT'N qui coupe la temporisation dès que la température à l'intérieure du boîtier atteint environ 20 60°C. L'ensemble des composants qui sont sur le couvercle son assemblés par un circuit imprimé (7) et ceux du schéma dont le circuit intégré IC2 (8). Quand la temporisation est coupée la led rouge clignote alors que cette dernière reste allumée lorsque la temporisation est en cours. 25 Le dispositif est alimenté par deux piles de 9V. A titre d'exemple non limitatif, le boîtier aura des dimensions de l'ordre de 170mm pour la longueur, 80mm pour la largeur et 65mm pour la hauteur. The drawing is made by a circuit board (7) which assembles the components with the terminals (3 and 4) and the LEDs (5 and 6) in the housing (1). The delay time can be changed without changing the scheme since there is just the programming of the integrated circuit IC2 (8) to change the duration. The protection of the resistors is achieved by the operation of the delay of the resistors (power chosen according to the ohmic value) and the CT'N which cuts off the time delay as soon as the temperature inside the casing reaches about 60 ° C. All the components that are on the cover are assembled by a printed circuit board (7) and those of the diagram including the integrated circuit IC2 (8). When the timer is off, the red led flashes while the latter remains on when the timer is running. The device is powered by two 9V batteries. As a non-limiting example, the housing will have dimensions of the order of 170mm for the length, 80mm for the width and 65mm for the height.

Le dispositif selon l'invention est particulièrement destiné aux organismes de contrôle 30 électrique. 10 The device according to the invention is particularly intended for electrical control bodies. 10
