Embodiment
Below in conjunction with drawings and Examples the utility model is described in detail.
As shown in Figure 1, the utility model comprises that one is arranged on the power transmission shaft 1 in the prior art permanent magnet mechanism, one is set in the separating brake power-assisted spring 2 of power transmission shaft 1 lower end, and separating brake power-assisted spring 2 one ends are fixed on the lower yoke 3 of permanent magnet mechanism, and the other end is spacing by a block 4 that is fixed on the power transmission shaft 1.When 2 initial setting up of separating brake power-assisted spring, separating brake power-assisted spring 2 is imposed a precompression.On the top of power transmission shaft 1 roller 5 is set, the axially parallel with roller 5 above roller 5 is provided with split axle 6 on the other hand, and hand split axle 6 two ends are supported on two fixed support plates 7 (as shown in Figure 2) rotationally.At the fixedly connected separating brake handle 8 of the anterior external part of hand split axle 6, at hand split axle 6 middle parts over against the position of roller 5 fixedly connected one cam 9 that contacts with roller 5.Fixedly connected one connecting lever 10 that resets in the rear end of hand split axle 6, the external part of connecting lever 10 of resetting is hung spring pin 11 by a nut fixedly connected, hang spring pin 11 and stretch in the spacing hole 12 that on supporting bracket 7, is provided with (as shown in Figure 1), hang spring pin 11 and can in spacing hole 12, move.At the middle part that hangs spring pin 11 one groove is set, articulates a return spring 13 in groove, the other end of return spring 13 is hung spring bolt 14 by one and is connected on the supporting bracket 7.
In the foregoing description, as shown in Figure 3, in the U type opening at power transmission shaft 1 top, locate with back-up ring 16 by two ends by a bearing pin 15 cross-under for roller 5.
In the foregoing description, spacing hole 12 is the center, is the annular slotted hole of radius with the axis of hand split axle 9 to the distance between the axis of hanging spring pin 11 that for the axis with hand split axle 9 extension spring pin 11 is slidingly arranged in the annular slotted hole.
When the utility model was applied in the tank type circuit breaker, supporting bracket 7 can be the sidewall of casing.
The utility model course of work is as follows: when emergency needs manual brake separating, the operator moves separating brake handle 8 clockwise, and separating brake handle 8 is by rotating band moving cam 9 rotations of hand split axle 6, presses down in the process in the rotation of cam 9, roller 5 rotates, and drives the motion vertically downward of power transmission shaft 1 do; Moving iron core 17 fixedly connected on the power transmission shaft 1 is also along with power transmission shaft 1 moves downward together, and along with the air air gap between moving iron core 17 and the upper magnet yoke 18 strengthens gradually, the closing retention force of permanent magnet falls sharply, and has reached the purpose of manual brake separating.
In the aforesaid operations process, because separating brake power-assisted spring 2 has precompression, therefore in the process that power transmission shaft 1 moves downward, separating brake power-assisted spring 2 has boosting power, makes permanent magnet mechanism can realize manual brake separating operation fast.Simultaneously, because when moving separating brake handle 8 and carry out sub-switching operation, the connecting lever 10 that resets on the hand split axle 6 drives extension spring pin 11 and moves along spacing hole 12, the return spring 13 stretching energy storage that drive, therefore working as sub-switching operation finishes, when unclamping manual brake separating handle 8, lean on the effect of return spring 13 that hand split axle 6 and cam 9 are automatically reset.
