Like Fig. 3, Fig. 4, Fig. 5 and shown in Figure 6; The utility model is by comprising that motor 10, electromagnetic clutch 11 and electronic output gear 14 form the motorized motions parts; Wherein, Motor 10, electromagnetic clutch 11 and electronic output gear 14 are connected in series and are installed on the rear bearing sheet 12.92, and second idler gear, 13.3 engagements on the leading screw 13.1 of first idler gear, 22, the first idler gears 22 and leading screw spindle assemblies 13 are installed in the outside of rear bearing sheet 12.92; The 3rd idler gear 13.4 that drives on the leading screw 13.1 rotates synchronously; Be transferred on mechanism's output gear 21, drive mechanical clutch 19 simultaneously and realize that with mechanism's output shaft 20 electric operating drives, this path is electronic output drive path; On front end panel 12.91, operate gear 24 through Bearing Installation isolated operation gear 23 and ground connection; Second idler gear 13.3, the 3rd idler gear 13.4 and mechanism's output gear 21 by the manual operation gear 13.2 of isolated operation gear 23, ground connection operation gear 24, leading screw 13.1 front ends and leading screw 13.1, leading screw rear end are formed the manual operation drive path jointly; During manual operation; Though second idler gear 13.3 also can drive first idler gear 22 and rotate with electronic output gear 14; But because the dropout effect of the electromagnetic clutch 11 that motor 10 connects is not rotated and can not drive motor 10.
During work, manual operation is selected handle 2.3.1 to be positioned at manual operation and is selected handle gathering sill 1.1.6 centre position under the normal condition, and isolated operation hole 1.1.3 and ground connection handle hole 1.1.4 all are in closed condition; The isolated operation handle and the ground connection operating grip of joining outward all can not insert, and can carry out electric operating this moment, in the time of need carrying out manual operation; If be isolated in the separating brake position, receive electric adhesive through breaker open operation state-driven latching electromagnet 8, can press manual operation and select handle 2.3.1 this moment; Compression spring 2.3.2 is compressed, and the manual operation that manual operation selects the groove on the handle 2.3.1 can get in the guidance panel 1 is selected in the handle gathering sill 1.1.6, and move left and right therein; When manual operation selective pan load module 2 selects handle 2.3.1 in handle gathering sill 1.1.6 is selected in manual operation, to move with manual operation; Be movable to and isolate that symbol 1.1.1 direction is opened isolator operation hole 1.1.3 or ground connection symbol 1.1.2 direction is opened earthed switch handle hole 1.1.4,, drive ejector pin briquettings 5.4 wrapping wires female 5.1 through first fairlead 5.5 simultaneously and be rotated counterclockwise certain angle when to isolating symbol 1.1.1 direction when moving; Insert outer isolated operation handle of joining this moment; Clockwise rotate, be transferred to mechanism's output shaft 20 through mechanical clutch 19, isolating switch is closed a floodgate through manual operation gear 13.2, leading screw main shaft 13.1, the 3rd idler gear 13.4, mechanism's output gear 21; If misoperation; Be about to outer isolated operation handle of joining and rotate counterclockwise, 13.1 rotations of leading screw main shaft drive ejector pin briquettings 5.4 and close direction to ground connection and move, and divide position ejector pin 12.82 to drive second bent plate 12.52, long connecting plate 12.42 and the second connecting lever plate 12.32 to move through isolating; Thereby drive right fore-set 12.22 and move down; Make right sincere sub 17 to move down, withstand the back ratchet 18 on the leading screw main shaft 13.1, make leading screw main shaft 13.1 can not continue rotation; Therefore force the isolated operation handle promptly to isolate in the direction of the clock and close the direction rotation; Effectively prevented misoperation, this interlocking has also played the position-limiting action when the isolating switch separating brake puts in place simultaneously, and promptly leading screw main shaft 13.1 closes the position by isolation and divides the position to rotate to isolate when dividing the position to isolating; Ejector pin briquetting 5.4 divides position ejector pin 12.82 finally to make sincere sub 17 to withstand ratchet 18 through isolating, and leading screw main shaft 13.1 can not be rotated further.When the isolated operation handle turns clockwise by correct direction; Arrive to isolate when closing, leading screw main shaft 13.1 drives ejector pin briquettings 5.4 and moves forward, and closes an ejector pin 12.61 through isolation and drives first bent plate 12.51, short connecting plate 12.41 and 12.31 motions of the first connecting lever plate; Thereby drive left fore-set 12.21 and move down; A left side sincere sub 15 is moved down, and ratchet 16 makes outer isolated operation handle of joining forbid being rotated further before withstanding, and the sign isolation is closed a floodgate and put in place; When in like manner inserting the ground connection operating grip operational grounding switch of joining outward; The direction of rotation of the ground connection operating grip of joining outward can be limited in earthed switch and close direction; Withstand ratchet through sincere son when ground connection puts in place and make outer operating grip of joining can not continue operation, the principle of ground connection sub-switching operation interlocking is with isolating sub-switching operation.
When carrying out above-mentioned isolating switch closing operation; Ejector pin briquetting 5.4 selects the rotation of handle 2.3.1 to divide position notch 12.1.2 to get into curved frid 12.1 the insides of inner core through isolating with manual operation; Move to isolating resultant displacement in curved frid 12.1 the insides of inner core along with isolating closing operation ejector pin briquetting 5.4 then, do not put in place if close a floodgate this moment, because of the restriction of the curved frid 12.1 of inner core; Ejector pin briquetting 5.4 can not rotate; Thereby manual operation select handle 2.3.1 can not be reset in the middle of initial position, ejector pin briquetting 5.4 must close a notch 12.1.1 through isolation when putting in place and can rotate isolating to close a floodgate, and extracts outer isolator operation handle of joining; Manual operation selects handle 2.3.1 can reset to the centre position; Through quick-action switch 9 electric signal is passed to relative breaker simultaneously, the notice relative breaker can be carried out closing operation, avoids isolating and carries out the relative breaker closing operation when not being incorporated into fully; Same because the restriction of the curved frid 12.1 of inner core; Ejector pin briquetting 5.4 must can divide a position notch 12.1.2 turn to curved frid 12.1 the insides of inner core through isolating in the three-station position that the position promptly isolate to be divided, ground connection is divided that mediate, and when preventing effectively that three-station is in ground connection and closes isolating switch is operated.Above-mentioned is the interlocking of isolated operation part, and the structure of ground connection operation part in like manner.Only after manual operation puts in place, when manual operation selects handle 2.3.1 to reset to the centre position, through quick-action switch 9 output electric signals, the electric operating loop is connected simultaneously, can carry out electric operating this moment.
