Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, enumerate following examples now, and the conjunction with figs. detailed description middle double-casing motor control cubicle of pressing of the present utility model is as follows:
As shown in Figure 1, press the double-casing motor control cubicle in of the present utility model, include the main bus bar chamber 13 that is arranged in the cabinet 26, be divided into upper and lower two-layer in the described cabinet 26, every layer is provided with one group of motor control mechanism, the described motor control mechanism that to be separately positioned on upper and lower two groups of two-layer motor control mechanisms be identical and work alone, the front panel of described cabinet 26 is control display floater door, and described control display floater door is to have and two groups of corresponding two groups of doors of motor control mechanism.
As shown in Figure 2, described control display floater door includes instrument door 20 and last Qianmen 21 on one group, and another organizes instrument door 22 and following Qianmen 23 down; Described upward Qianmen 21 and identical being provided with of following Qianmen 23 structures: observation window 25, the isolating switch hand behaviour mechanism 11 that links to each other with corresponding motor control mechanism in the cabinet 26, the body of rod is arranged on earthed switch action bars termination 29 and the earthed switch action bars locking press button 30 in the cabinet 26, described upward instrument door 20 and following instrument door 22 structures are identical, and various Displaying Meters all are set.
As shown in Figure 1, described two groups of motor control mechanisms earthed switch action bars 9 of including control room 1, the main switch chamber 5 that links to each other with main bus bar chamber 13, the outlet cable vault 16 that links to each other with main switch chamber 5 and linking to each other with outlet cable vault 16 with main switch chamber 5 respectively.
