Abstract

Dispositif permettant d'éviter les micro-coupures électriques. Il est constitué par une double alimentation du récepteur, l'une normale, l'autre de secours. L'alimentation normale passe par une bobine de fil conducteur avant d'arriver au récepteur. Cette même alimentation commande en direct la base d'un transistor qui assure la mise en circuit du réseau d'alimentation de secours lorsqu'une micro-coupure se présente, et ce avant que cette micro-coupure ait franchi la longueur de la bobine. Le récepteur se trouve donc toujours alimenté. Le dispositif est principalement destiné à équiper les appareils sensibles aux micro-coupures, par exemple: mémoires vives d'ordinateurs.Device to avoid electrical micro-cuts. It consists of a double power supply to the receiver, one normal, the other backup. Normal power passes through a coil of lead wire before reaching the receiver. This same power supply directly controls the base of a transistor which ensures the circuitry of the emergency power supply network when a micro-cut occurs, and this before this micro-cut has crossed the length of the coil. The receiver is therefore always powered. The device is mainly intended to equip devices sensitive to micro-cuts, for example: computer memories.

Description

DISPOSITIF ANΠ-MICRO COUPURES ANΠ-MICRO CUT-OFF DEVICE
La présente invention a pour objet, à titre de produit industriel nouveau, un dispositif permettant d'éviter les ruptures d'alimentation électrique sur tous les appareils sensibles aux micro-coupures. Ce dispositif est remarquable en ce sens que le récepteur sensible est alimenté par deux sources ; l'une .normale, l'autre de secours. L'alimentation normale est retardée par un passage dans une bobine de fil conducteur -de longueur déterminée. Une micro-coupure sur l'alimen¬ tation normale provoque la bascule sur l'alimentation de secours avant que cette micro-coupure ne' soit arrivée au récepteur.The object of the present invention is, as a new industrial product, a device making it possible to avoid power supply interruptions on all devices sensitive to micro-cuts. This device is remarkable in the sense that the sensitive receiver is powered by two sources; one normal, the other emergency. The normal supply is delayed by passing through a coil of conductive wire of determined length. A micro-cleavage on alimen¬ normal tation causes the switch to the backup power before that power failure does' is arrived at receiver.
• • Le schéma, figure 1, représente un exemple simplifié du dispositif. En Ul, nous avons .l'alimentation normale du récepteur "R" ; en U2, l'alimentation de secours. • • The diagram, figure 1, represents a simplified example of the device. In Ul, we have normal supply of the "R"receiver; in U2, the emergency power supply.
L'alimentation Ul passe par la bobine S dont la longueur du fil conducteur est calculée en fonction du temps de réponse du transistor.The supply Ul passes through the coil S, the length of the conductive wire of which is calculated as a function of the response time of the transistor.
En fonctionnement normal, l'alimentation de "R" est assurée par Ul, qui alimente également là base "du transistor.In normal operation, the supply of "R" is provided by Ul, which also supplies the base " of the transistor.
Une coupure d'alimentation (sur Ûl) provoque l'arrêt de l'alimen¬ tation de la base du transistor et donc le passage direct du courant (U2) sur le récepteur "R".A power cut (on Ûl) causes the power supply to the base of the transistor to stop and therefore direct current (U2) to pass over the receiver "R".
Au retour du courant. (Ul) une temporisation permet à l'alimentation de secours de se maintenir le temps de passage dans la bobine S.At the return of the current. (Ul) a time delay allows the emergency power supply to maintain the passage time in the coil S.
La longueur du fil conducteur, constituant la bobine S doit permet¬ tre â l'alimentation de secours d'intervenir avant que cette micro- coupure soit arrivée au récepteur;The length of the conductor wire constituting the coil S must allow the emergency supply to intervene before this micro-cut has reached the receiver;
Par exemple : Pour un transistor dont le temps de réponse est infé¬ rieur à 200 nano-secondes, la longueur du fil doit être supérieure à 7,20 mètres pour un fil de cuivre.For example: For a transistor whose response time is less than 200 nanoseconds, the length of the wire must be greater than 7.20 meters for a copper wire.
Il est bien entendu que la présente description ne constitue qu'un exemple non limité par l'utilisation de produits ou composants, ceux- ci pouvant être de conductivitë ou de résistivité différentes, de tech¬ nologies électriques, électroniques ou mécaniques, en quantité identique ou différente, disposés tels que sur l'exemple ou non.It is understood that the present description constitutes only an example not limited by the use of products or components, these being able to be of different conductivity or resistivity, of electrical, electronic or mechanical technologies, in identical quantity or different, arranged as in the example or not.
Le dispositif est particulièrement destiné à équiper les appareils sensibles aux micrc—coupures, par exemple., les mémoires vives d'ordina¬ teurs. .The device is particularly intended for equipping devices sensitive to micro-cuts, for example. RAM memories of computers. .
