1. , for a remote electric operating mechanism for power distribution cabinet dual-power transfer switch, it is characterized in that:

  • comprise for clamping the front stall be arranged on external Connection Block, two electromagnetic drive mechanisms be arranged in front stall, manual-operating mechanism and be electrically connected with electromagnetic drive mechanism there is control circuit module in the intelligence of radio receiving transmitting module;

    Each electromagnetic drive mechanism comprises mounting bracket, electromagnet, armature, drive rod and provides the extension spring of reseting elasticity for armature;

    Mounting bracket is provided with for being arranged on the first installation portion on front stall inwall, for installing the second installation portion of electromagnet, the rotating shaft as drive rod center of rotation, the hook hole for hooking extension spring one end and for the rotating support portion as armature center of rotation;

    Electromagnet comprises plug;

    The middle part of armature is provided with the pivot joint limiting section with the rotating support portion adaptation of mounting bracket, one end of armature is provided with the adsorption section with plug adaptation, the other end of armature is provided with the plate portion for driving the first pole to rotate, and armature is provided with the hanging hole for the hooking extension spring other end between plate portion and pivot joint limiting section;

    Drive rod comprises for triggering corresponding first pole and second pole of entering electric on off mechanism, and the first pole and the second pole are combined into V-shaped, and the opening of this V-shaped is towards rear;

    The connecting place of the first pole and the second pole is provided with the spacing axis hole with the rotating shaft adaptation of mounting bracket, and the first pole is positioned at the top of the second pole;

    First pole is provided with the jack with armature plate portion adaptation away from one end of spacing axis hole;

    The plate portion of armature is inserted in the jack of the first pole;

    The plate body of the second installation portion in mounting bracket is arranged along plumb line direction, and the center is provided with a through hole along the longitudinal direction, and the second installation portion is set on the front end of plug by this through hole;

    Each mounting bracket away from the side of another electromagnetic drive mechanism plate body backward vertical bending extend to form the first installation portion, first installation portion is provided with four installation screws, the sidewall adjacent with this first installation portion of front stall is provided with four and installs open-work, each screw is tightened in a corresponding installation screw after installing open-work through corresponding one, thus mounting bracket is fixedly installed on a corresponding sidewall;

    The plate body of mounting bracket opposite side backward vertical bending extends to form the supporting board parallel with the first installation portion, and the rear end of supporting board is as rotating support portion;

    Hook hole to be arranged on the plate body of supporting board front end, and squarely along left and right run through supporting board plate body;

    The part plate body on supporting board top first vertical bending towards the direction horizontal-extending close to another electromagnetic drive mechanism, vertical bending extend to form rotating shaft support plate portion towards upward direction again, this rotating shaft support plate portion is provided with axis hole, and a bearing pin as rotating shaft is fixed in this axis hole;

    The top of rear end, rotating support portion is provided with a upper limit boss that level is outstanding backward, and the bottom of rear end, rotating support portion is provided with a lower limit boss that level is outstanding backward, and upper limit boss and the clamping of lower limit boss form a spacing breach;

    The top of lower limit boss is also provided with the anticreep groove be communicated with spacing breach;

    Manual-operating mechanism comprises two Manual press seesaws;

    The antetheca center of front stall is provided with square hole along the longitudinal direction, and the inwall of front stall antetheca is provided with pivoted hole;

    Each Manual press seesaw is provided with Manual press panel part, to the pivot joint rotating shaft that pivoted hole is rotationally connected, for being connected to the first manual lever of a corresponding seesaw button upper end and the second manual lever for being connected to this seesaw button lower end;

    Each Manual press panel part is arranged in the square hole of front stall antetheca, and pivot joint rotating shaft is arranged on the left and right sides of each Manual press panel part inwall, and is respectively plugged in a corresponding pivoted hole, thus each Manual press panel part back and forth can be shaken around pivot joint rotating shaft;

    Each drive rod, in reciprocating rotation, triggers corresponding one by its first pole and the second pole and enters electric its control circuit of on off mechanism break-make;

    When each Manual press seesaw back and forth shakes, trigger corresponding one by the first manual lever and the second manual lever and enter electric its control circuit of on off mechanism break-make.
