LOW VOLTAGE DISTRIBUTION PANEL

The invention relates to a low voltage distribution panel meant for supplying some individual electrical loads or some load groups from general panels or in the secondary of the transformers MT/JT. The problem solved by the invention consists in providing a distribution panel whose distributing valves have the force coupling fixed on the back of the valve (C), the control connector being movable relative to a control plug, a mechanical case (D) provided with a cog rack driving device (E) providing: - a broaching position of the valve (C) with corresponding mechanical and electrical signalling, wherein the force and control circuits are open; - a test position, wherein: a) the force circuit is open; b) the coupling of the connector with the control plug takes place by means of a cog rack driving mechanism (E) simultaneously with blocking the ends of the cog rack driving mechanism (E) in some trays (B) for separating the valves (C), and the mechanical signalling of the test position; a broached position, in which, a mechanism with a driving screw (5) moves the whole valve assembly (C) relative to the cog rack driving mechanism (E) so as to close the power circuit physically, to ensure the mechanical signalling of the position of valve (C) and, by an electrical blocking, to provide the control voltage of the power switching apparatus, because of the mechanical blocking, on this position, the driving of the cog rack mechanism (E) and of the control connector, respectively, being impossible. Invenţia se referă la un tablou de distribuţie, de joasă tensiune, destinat alimentării unor sarcini electrice individuale sau unor grupuri de sarcini din tablouri generale sau din secundarul transformatoarelor MT/JT. Problema, pe care o rezolvă invenţia, este realizarea unui tablou de distribuţie, ale cărui sertare de distribuţie au cupla de forţă fixă pe spatele sertarului (C), fişa de comandă fiind mobilă în raport cu o priză de comandă, o casetă mecanică (D) prevăzută cu un mecanism de acţionare cu cremalieră (E) asigurând: - o poziţie de broşat a sertarului (C), cu semnalizările mecanice şi electrice corespunzătoare, în care circuitele de forţă şi comandă sunt deschise; - o poziţie de test, în care; - a) circuitul de forţă este deschis; b) cuplarea fişei cu priza de comandă are loc prin intermediul unui mecanism de acţionare cu cremalieră (E), simultan cu care are loc blocarea capetelor mecanismului cu cremalieră (E) în nişte tăvi de separare (B) a sertarelor (C), şi s
