Abstract

Dispositif d'épreuve en sécurité intrinsèque d'appareils électriques antigrisouteux à nombreux circuits. Ce dispositif constitue un appareil d'épreuve, à brancher en série avec les circuits à vérifier, qui renferme une source de courant 1, un moyen de limitation de courant 2 et des transmetteurs de signaux 26-30 et 52-59 indiquant le passage de courants d'épreuve, qui est adapté dans ses dimensions aux embouts enfichables des appareils et qui présente au moins une barrette à fiches multiples 12, 36 et, en face, les transmetteurs de signaux. L'invention intéresse notamment l'épreuve de combinaisons d'appareils de commutation blindées du fond des mines.Intrinsically safe test device for anti-seizure electrical devices with many circuits. This device constitutes a test apparatus, to be connected in series with the circuits to be checked, which contains a current source 1, a current limiting means 2 and signal transmitters 26-30 and 52-59 indicating the passage of test currents, which is adapted in its dimensions to the plug-in ends of the devices and which has at least one strip with multiple plugs 12, 36 and, opposite, the signal transmitters. The invention relates in particular to the testing of combinations of armored switchgear from the bottom of mines.
