Operation principle of the present invention is as follows:
See Fig. 1-Fig. 3, when manual operation indicating knob 12 by trip positions (Trip) to reset position (Reset) time, in rotary course, cam 4 is followed indicating knob 12 and is rotated counterclockwise together, and promote warning cam 2 and do reverse rotation, promote deflecting cam 3 by warning cam 2 again and do rotating Vortex, after indicating knob 12 operates certain angle, by reset position (Reset) to automatic control position (Auto), in this process, due to the effect of reaction spring, warning cam 2 and deflecting cam 3 are back moved, now warning cam 2 and deflecting cam 3 is stoped to move respectively by warning retainer 7 and dropout retainer 6, the spring of warning cam 2 and deflecting cam 3 is made to produce energy storage, when indicating knob 12 operates automatic control position (Auto), middle retainer 5 is under reaction spring effect, fasten cam 4, automatic control position (Auto) can be rested on, simultaneously, middle retainer 5 promotes rocking arm 10 and works.Only report to the police and do not disconnect main circuit when it reliably can realize overload, overcurrent; Just disconnect main circuit in a short-circuit situation and the fire-fighting function of reporting to the police.
See Fig. 4-Fig. 7, when indicating knob 12 is placed in automatic control position (Auto), warning cam 2 and deflecting cam 3 are buckled on warning retainer 7 and dropout retainer 6 respectively, and middle retainer 5 fastens cam 4 at M point, and deflecting cam 3 is retainer in N point fastens simultaneously; If deflecting cam 3 is rotated counterclockwise around O point, in drive, retainer 5 turns clockwise, then whole mechanical unlocking.KB0 control and protective switching device is made to disconnect like this.
See Fig. 8-Fig. 9; when there is the generic failures such as overload, overcurrent; warning retainer 7 is subject to the power from L direction; after warning retainer 7 is rotated to an angle; warning cam 2 is threaded off; and rotate to an angle, drive Alarm contactor action (omitting in Alarm contactor figure) in KB0 control and protective switching device.See Fig. 4-Fig. 5, because warning retainer 7 independently can be rotated counterclockwise certain angle, and thread off retainer 6 when being rotated counterclockwise, interlock is realized by the cooperation in A face and B face, namely when dropout retainer 6 is rotated counterclockwise, drive warning retainer 7 to do to move in the same way simultaneously, now, being rotated counterclockwise of warning retainer 7 cannot drive dropout retainer 6, so deflecting cam 3 is still buckled on dropout retainer 6, see Fig. 6 and Fig. 7, middle retainer 5 maintains original position and namely still interlocks with deflecting cam 3, namely overload is realized, overcurrent is only reported to the police not the function of " tripping operation ".
See Figure 10-Figure 11; during short trouble; the power in dropout retainer 6 one P directions is given in push pedal 8; time dropout retainer 6 counterclockwise rotate, warning cam 2 and deflecting cam 3 are all threaded off, simultaneously deflecting cam 3 drive in retainer 5 turn clockwise; make whole mechanical unlocking; KB0 control and protective switching device disconnects, simultaneously indicating knob 12 also by automatic control position (Auto) to trip positions (Trip), the function of disjunction main circuit when namely realizing short circuit.
See Figure 12, during manual disjunction main circuit, indicating knob 12 is threaded to disjunction position (Off) by automatic control position (Auto), and cam 4 backs down middle retainer 5, and middle retainer 5 is turned clockwise, and disconnects main circuit.
