Shown in Figure 4, brake separating mechanism of the present utility model comprises tripping electromagnet 6, the sincere son assembling 20 of separating brake and separating brake dropout assembling 21.The sincere son assembling 20 of separating brake and separating brake dropout assembling 21 positioning supports are on left plate 4, and the trip shaft 21a in separating brake dropout assembling 21 is by tripping electromagnet 6 and push pedal 55 drive actions or drive rotation by on/off switch cam 28.After combined floodgate, the one end in the separating brake dropout plate 56 in the sincere son assembling 20 of separating brake is subject to the restriction of the trip shaft 21a in separating brake dropout assembling 21, and separating brake dropout plate 56 cannot rotate, and combined floodgate is kept.
When on-load switch needs separating brake, the trip shaft 21a that tripping electromagnet 6 is promoted in separating brake dropout assembling 21 by push pedal 55 rotates, when the yielding groove 21b that trip shaft 21a turns on it separating brake dropout plate 56 be positioned in the sincere son assembling 20 of separating brake turns round on route, the maintenance of the separating brake dropout plate 56 in the sincere son assembling 20 of separating brake is removed, thus reaches separating brake function.
Shown in Fig. 5 and Fig. 6, output mechanism of the present utility model comprises a pair sluice separating spring 19, needle bearing 22, exports clamping plate 23, roller axle 24, bearing holder (housing, cover) 25, separating brake semiaxis 54 a pair, the entirety composition of output mechanism is by exporting clamping plate 23 as the use of supports, and exporting clamping plate 23 for a pair by output clamping plate connecting bolt 50 interval parallelly links together.The fulcrum that a pair exports clamping plate 23 is provided with two rolling bearings 52 by rotating shaft 51, two rolling bearings 52 are supported on left and right side plate 4,5 respectively, thus a pair output clamping plate 23 is supported on left and right side plate 4,5, the rolling bearing 52 that right plate 5 side is also stretched out in rotating shaft 51 is simultaneously connected with spacing connecting plate 58, and spacing win in succession 58 upper end through the stopper slot 12a on bent plate 12, bent plate 12 is fixed on the outer surface of right plate 5.Needle bearing 22 and roller axle 24 are arranged on the different position of a pair output clamping plate 23, are in triangle relation with rotating shaft 51.Bearing holder (housing, cover) 25 and separating brake semiaxis 54 are arranged on same output clamping plate 23.Export between clamping plate 23 at a pair in addition and a sluice separating spring hanging scroll 57 is also installed.One end of a pair sluice separating spring 19 hangs on sluice separating spring hanging scroll 57, and the other end hangs on connecting lever axle 48.Bearing holder (housing, cover) 25 is for use that is fixing and spacing output clamping plate 23.
After on/off switch cam 28 promotes needle bearing 22, make a pair output clamping plate 23 around the shaft 51 axis rotate, drive rotating shaft 51 autobiography simultaneously, the rotation of rotating shaft 51 drives spacing 58 swings of winning in succession, due to the restriction of the stopper slot 12a on bent plate 12, spacing win in succession 58 pendulum angle be restricted, thus the angle of rotating shaft 51 autobiography is also restricted, and then restriction a pair export clamping plate 23 around the shaft 51 axis rotate angle, thus formed a feed motion process.
Clamp 18 after axle is provided with an on-load switch combined floodgate on hanging spring shaft 13 in addition is also wound with the rear clamp reduction torsion spring 18a of an on-load switch combined floodgate, after on-load switch combined floodgate, clamp reduction torsion spring 18a one end hooks on left plate 4, and the other end hooks and closes a floodgate on rear clamp 18 at on-load switch.When clamp 18 after on-load switch closes a floodgate pins extension spring extension pin 35, earthed switch cannot close a floodgate.P cock 17 is in normal battle simultaneously.P cock 17 is arranged in supporting bracket 39, closes a point indicator board driving carry out action by earthed switch.
Separating brake semiaxis 54 swings as the use of closing point instruction, the roller axle 24 maintenance effect played combined floodgate after tangent with separating brake dropout plate 56.
In the utility model, each components and parts form the operating mechanism being specifically designed to ring main unit circuit breaker after connecting, its advantage is, large power output can be provided, the on/off switch speed characteristics that abundant guarantee circuit breaker is high, the short circuit interruption performance requirement of generator circuit breaker harshness can be met completely, can reach the failure on-off ability of rated short circuit current 80kA, operating mechanism failure rate is low, mechanical strength are high, and the life-span more can up to 10,000 times.
Operating principle during utility model works is as follows:
Incorporated by reference to description above, operation principle is below write in detail a bit, thanks!
On-load switch on/off switch process:
Electric energy-stored making process: energy storage motor 3 drives the energy storage gear 7 be connected with its output shaft to rotate, and the engagement that rotates through of energy storage gear 7 drives gear wheel 27 to rotate, the one-way clutch that rotates through of gear wheel 27 drives manually conjunction split axle 29 to rotate clockwise, manual conjunction split axle 29 drives on/off switch cam 28 to rotate by combined floodgate connecting lever 45, on/off switch cam 28 promotes needle bearing 22, make a pair output clamping plate 23 around the shaft 51 axis rotate, drive rotating shaft 51 autobiography simultaneously, the rotation of rotating shaft 51 drives spacing 58 swings of winning in succession, forms a feed motion process.
Closing by hand process: operator dynamic circuit connector split axle 29 clockwise, manual conjunction split axle 29 drives on/off switch cam 28 to rotate clockwise by combined floodgate connecting lever 45, on/off switch cam 28 promotes needle bearing 22, make a pair output clamping plate 23 around the shaft 51 axis rotate, drive rotating shaft 51 autobiography simultaneously, the rotation of rotating shaft 51 drives spacing 58 swings of winning in succession, forms a feed motion process.This process is due to the effect of one-way clutch, and gear wheel 27 does not rotate.
After electric switch-on or closing by hand, because the separating brake dropout plate 56 in the sincere son assembling 20 of separating brake plays the maintenance effect after combined floodgate with roller axle 24 is tangent.After adding combined floodgate, the one end in the separating brake dropout plate 56 in the sincere son assembling 20 of separating brake is subject to the restriction of the trip shaft 21a in separating brake dropout assembling 21, and separating brake dropout plate 56 cannot rotate, and therefore closing a floodgate is kept, now a pair sluice separating spring 19 accumulation of energy.
