Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
As shown in Figure 1, a kind of shown in Figure 1: duplicate supply mounting panel 1, circuit breaker 1, circuit breaker 23, duplicate supply controller 4, shift fork 1, shift fork 26, cam mechanism 7, conversion thrust mechanism 8, circuit breaker one handle 9, circuit breaker one handle 10, cam mechanism alignment pin 11, hand rotation handle hole 12, alignment pin 13, near switch 15.Circuit breaker 1 is installed in the both sides of duplicate supply mounting panel 1 respectively with circuit breaker 23 and fixes.Circuit breaker 1 is imported the two-way different electrical power respectively with circuit breaker 23; The input power supply that major control is different; The action of circuit breaker is controlled by same road control circuit; Duplicate supply controller 4 is main show circuit-breaker status with and the control circuit of travel switch conversion is arranged, can carry out conversion and control to motor 14 both forward and reverse directions.The mechanism driving of shift fork one 5 major control break devices, one 2 combined floodgates and disjunction; The mechanism driving of shift fork 26 major control break devices, 23 combined floodgates and disjunction; Cam mechanism 7 connects motors 14 and mounting cam mechanism alignment pin 11 and hand rotation handle hole 12 in the above, and conversion thrust mechanism 8 mainly is to shift fork 1 and shift fork 26, and conversion thrust mechanism 8 is positioned on the mounting panel; When one of them shift fork promotes it; The conversion thrust mechanism turns over an angle, and promotes another shift fork motion, drives switch knob on the shift fork again and carries out division and combination work.The conversion thrust mechanism is other to have 2 near the startup of switch 15 control motors 14 with close and positive and negative rotation.Circuit breaker one handle 9, circuit breaker one handle 10 are installed in respectively in shift fork 1 and shift fork 26 open slots;, motor 14 drives cam mechanism 7 when rotating; And drive shift forks 1 by the cam mechanism alignment pin on the cam mechanism 7 11 and move up; Notch on the shift fork 1 directly promotes circuit breaker one handle 9 and upwards promotes circuit breaker 1 and close a floodgate, the interlock conversion thrust mechanism 8 at shift fork one 5 tops, by conversion thrust mechanism 8 again pushing pitch 26 and move downward; Shift fork 26 moves down drive circuit breaker one handle 10 and moves down, and realizes the action of circuit breaker 23 separating brakes.When motor 14 when opposite direction turns round, drive another pin on the cam mechanism alignment pin 11 and drive toggle switch and change 26 and change 26 by moving toggle switch again and upwards promote circuit breaker two handles 10, the combined floodgate of realization circuit breaker 23,
Cam mechanism alignment pin 11 is formed by two, is respectively applied in shift fork 1 and shift fork 26 open slots, and hand rotation handle hole 12 is installed in cam mechanism 7 and mainly plays when motor 14 breaks down and can carry out hand-reset.Shift fork alignment pin 13 is mounted on the organization soleplate, has six, is installed in respectively in shift fork 1 and shift fork 26 grooves, plays the effect of guiding.
Among Fig. 2; The direction that its arrow refers to drives cam mechanism 7 when being motor 14 work and rotates, and the opening part that cam mechanism alignment pin 11 is stuck in shift fork 1 rotates together, and shift fork 1 moves to arrow; At this moment inside the groove in the shift fork 13 alignment pins 13 being arranged is to be used for guide effect shift fork 1 is moved up and down; When moving upward, stir circuit breaker one 2 handles and realize circuit breaker one combined floodgate, and shift fork 1 promotes conversion thrust mechanism 8 backward when moving upward; The rotation another side rotates pushing to pitch 26 again forward and moves downward and stir circuit breaker 23 handles by shift fork 26 and realize breaker open operation, realizes the conversion of circuit.Be to touch near switch 15 to touch the back and be transferred to stopping of duplicate supply controller 4 control motor 14 work to signal at conversion thrust mechanism 8 in conversion in addition; When duplicate supply controller 4 receives the opposite direction signal; Motor 14 inverse cam mechanisms 7 are to running in the other direction; At this moment another alignment pin 11 is inserted into and stirs circuit breaker 23 after rotating on the opening of shift fork 26 and realize circuit breakers two combined floodgates on the cam mechanism 7; And shift fork 26 promotes conversion thrust mechanism 8 when moving upward backward, rotates another side and rotates pushing to pitch 1 again forward to move downward and stir circuit breaker one 2 handles by shift fork 1 and realize breaker open operation, realize the conversion of another road circuit.
Present technique is through motor 14 controls; And rotate to drive shift fork through cam mechanism and drive breaker closing; And the conversion through thrust mechanism promotes another shift fork and drives another breaker open operation; Realize the conversion of circuit, and give the cut-out of duplicate supply controller control motor 14 near the switch transmission signals by the conversion and control of thrust mechanism.Present technique on structure simple but transfer process dependable performance, the manual-operating mechanism of configuration can be realized changing when breaking down after.
The utility model does not relate to all identical with the prior art prior art that maybe can adopt of part to be realized.
