Definitions

• the first state-of-the-art manufactured electric cabinets had a smooth, closed door that allowed access to the inside of the drawer only after opening, usually with that is, the connectors and the entire electrical system were confined within the cabinet or the pull-out drawer and could only be accessed through the effective opening of the door, which was a serious accident for users of these electrical cabinets as Until then, there was no means of security other than the protection the drawer or cupboard door offered.
• the electrical cabinets evolved to include a cutout on the front face of the pull-out door allowing the user to access the drawer operating mechanism and to switch on the system without, however, opening the drawer. drawer or electric cabinet door.
• the pull-out safety device was positioned internally and the pull-out drawer or cabinet door had indentations on the front face of the door so that they could be exposed for manipulation, the equipment drive devices provided inside cabinet and / or drawer.
• CCM motor control center
• circuit breaker activation reveals that the The drive is positioned on the CCM drawer door and the body of this circuit breaker is positioned internally, coupling it to said handle as the door is closed, to promote operation externally.
• the pull-out drive device nowadays uses the same concept where, through a cutout in the pull-out door, the user accesses the drive system's electrical device without it is necessary to open the door of said drawer.
• this system operates from a door-mounted safety device which connects, when the pull-out drawer door is in the "closed” position, to a transmission assembly provided with a plurality of gears, this one being in turn it interconnects with at least two laminar plates, moving the whole assembly and activating or locking the entire electrical system of the CCM type cabinet.
• this system features external operation of the pull-out drawer of a CCM with autonomous safety device attached to the door, and the safety device is, in this drive system, positioned externally, a fact that promotes greater safety in handling, especially in cases where the CCM - Motor Control Center cabinet does not have all of its drawers in use, as in these cases the drawer door remains closed and sealed, with no clipping corresponding to the safety device. internal.
• Figure 1 shows an organization chart of interconnection between the component parts of the claimed system, which allows the entire electrical system of the CCM cabinet drawer to function safely;
• Figure 2 shows a perspective view of a state-of-the-art CCM-type cabinet illustrating two pull-out drawers with the tear-free door and an electrical system crank-type key, in this case , the drive is internal, therefore the opening of the door is necessary to energize the electrical system of the cabinet;
• Figure 3 shows a perspective view of a CCM cabinet, also belonging to the state of the art, illustrating two pull-out drawers with the cut-out door which allows the drawer to be operated externally, but totally compromises the sealing. panel in the absence of the drawer, and in this configuration, the drawer drive system can be internal, requiring the opening of the door for the electrical system drive, or external with the drawer door closed, where the actuation will take place through the cutout practiced in the said door; and [019]
• Figure 4 shows a perspective view of a CCM-type cabinet illustrating two pull-out drawers with the door provided with a stand-alone safety device attached to the door for external drawer operation, operating only with the door closed.
• the present invention "SYSTEM FOR EXTERNAL DRIVE OPERATION OF A CCM WITH A DOOR-COUPLED SAFETY DEVICE"
• a system 1 developed to be applied to external drive of CCM 3 drawer operation 2, said system.
• a stand-alone safety device 4 specially designed to be positioned on the door 5 of a CCM 3 drawer.
• This system operates from three main sets of component elements, namely a safety device 4 coupled to door 5, which connects, when door 5 of the drawer 2 is in the "closed” position, to a transmission assembly 6 is provided with a plurality of gears which in turn interconnect with laminar plates 7, moving the entire assembly and driving or locking the entire electrical system of the CCM cabinet 3.
• said system 1 presents the external operation drive of the drawer 2 of a CCM 3 with autonomous safety device 4 coupled to the door S, and the safety device 4 is externally positioned in this drive system.
• This promotes greater safety in handling, especially in cases where the CCM 3 - Motor Control Center cabinet does not have all of its drawers 2 in use, because in these cases, door 5 of drawer 2 remains closed and sealed, with no clipping corresponding to the internal security device.
• door 5 is fully closed and the user activates the internal electrical system via external safety device 4, practiced in the center of CCM 3 door 5.
• drawer 2 remains closed during drive procedures is critical for the user as the danger of explosion exists and is imminent and if the door is open it will cause injury to the user.
• the safety device 4 presented in this drive system 1 has to be fully secured since, in addition to the drive being external, ie embedded in the door 5 of the drawer 2, it is particularly by means of a key 8 special coupling to safety device 4 and external drive, which are triggered the connection steps that first promote function tests, before energizing the heavy equipment to which they are connected.
