Description

[0001] DESCRIPTION

[0002] A PLANT FOR SUPPLYING A WORKING ELECTRICAL POWER TO CORRESPONDING APPARATUSES OF AN OPERATIONAL COMPLEX.

[0003] Field of application of the present of the present invention

[0004] The present invention relates to a plant for supplying a working electrical power to corresponding apparatuses of an operational complex, in particular in the form of an industrial complex.

[0005] Background art

[0006] Plants are known for supplying a working electrical power to corresponding apparatuses of an industrial complex occupying a respective environment, or area, in which the plant comprises electric panel means, a plurality of electrical loads, in particular comprising one or more corresponding electric motors, connected to said electric panel means to receive therefrom a corresponding electrical power, and a system for controlling the electrical power that is provided to said electrical loads and whose components are arranged directly inside the electric panel of the plant.

[0007] In these already known plants, the work for the personnel assigned to said system for controlling the electrical power is rather demanding and tiring, as well as scarcely efficient, since the control devices located inside the electric panel force the assigned personnel, whenever a corresponding activity must be carried out, to move between the respective loads and said electric panel, with consequent excessive effort and a significant loss of time.

[0008] Furthermore, in the already known plants, the use of electrical cables in the plant between the electrical loads and the electric panel proves to be excessive, with consequent high making costs.

[0009] Moreover, in the already known plants, it is not always possible to ensure a maximum intervention efficiency for the assigned personnel, because in order to perform the appropriate operations they necessarily have to reach the electric panel, with consequent excessive loss of time.

[0010] Summary of the invention

[0011] Therefore, with the present invention a new and alternative solution is proposed with respect to the solutions known so far, and in particular the aim is to overcome one or more of the drawbacks or problems mentioned above and / or to meet one or more of the needs referred to above, and / or in any case felt in the art, and in particular clear from what has been stated above.

[0013] In this manner, it is possible to ensure the maximum working convenience for the personnel assigned to said system for controlling the electric power that is provided to the electrical loads affected by the adverse event, which personnel can easily intervene and restore the correct operation of the system and / or the operational complex may further be configured with a significant saving in the use of electrical cables for safety signals, which electrical cables no longer need necessarily to be extended to reach said electric panel.
