Description
Technical field
The utility model belongs to switchgear field, relates to the separating brake holding device of a kind of circuit breaker, particularly a kind of circuit breaker.
Background technology
Now, the indoor switch equipment for electric power system is often used vacuum circuit-breaker as protection and the control unit of grid equipment, industrial and mining enterprises' power-equipment.Due to the special superiority of vacuum circuit-breaker, be particularly useful for requiring the frequent operation under rated operational current, or the place of repeatedly cut-offfing short circuit current.Separating brake holding device is the pith that affects circuit breaker effect.
Existing separating brake holding device comprises the sincere son of connecting lever, contiguous block and separating brake.During breaker closing, connecting lever turns clockwise around self assembled shaft, and now contiguous block is rotated counterclockwise around the rotating shaft that is connected to the sincere sub-lower end of separating brake, when contiguous block reaches dead point, impels the power that connecting lever turns clockwise to disappear.Now connecting lever is connected piece and pushes down and can not reset, thereby makes circuit breaker keep closing a floodgate.Now three's relative position as shown in Figure 3.During breaker open operation, the sincere son of separating brake is rotated counterclockwise certain angle around self assembled shaft, makes contiguous block leave dead-centre position, and contiguous block can rotate.Now connecting lever is rotated counterclockwise 35 degree around self assembled shaft, and extruding contiguous block turns clockwise, thereby makes breaker open operation, and now three's relative position as shown in Figure 4.The parts motion process of original separating brake holding device is relatively loaded down with trivial details, is prone to fault.
Utility model content
The utility model provides a kind of separating brake holding device of circuit breaker, and object is the motion process of having simplified each parts, moves more reliable.
To achieve these goals, the technical scheme that the utility model is taked is:
The separating brake holding device of described circuit breaker, comprises the sincere son of separating brake and connecting lever, is also included in "on" position and presses down the closing magnet master part that connecting lever is stated in residence, and described closing magnet master part is arranged on the sincere son of described separating brake by rotating shaft; Between the sincere son of described separating brake and described closing magnet master part, be provided with the locking structure that prevents that under "on" position described closing magnet master part from rotating relative to the sincere son of described separating brake, between described closing magnet master part and the sincere son of described separating brake, be provided with back-moving spring.
Described locking structure comprise be located at described closing magnet master part one side lock part and be located at the locking face engaging with described lock part on the sincere son of described separating brake, described closing magnet master part is provided with a side of described lock part near the rotating shaft of described connecting lever.
Described closing magnet master part comprises one section of circular arc concentric with the rotating shaft of described closing magnet master part near the top outer rim of described locking face, described circular arc described closing magnet master part be not provided with described lock part a side and and described locking face between gapped.
Adopt technique scheme, simplified motion process, self-operating is more reliable, can also avoid separating brake not in place.Part of the present utility model can adopt casting, has saved manufacturing cost.

Embodiment
Contrast accompanying drawing below, by the description to embodiment, embodiment of the present utility model is described in further detail, to help those skilled in the art to have more complete, accurate and deep understanding to inventive concept of the present utility model, technical scheme.
As shown in Figure 1 and Figure 2, the utility model provides a kind of separating brake holding device of circuit breaker, comprises closing magnet master part 2, separating brake sincere sub 1 and connecting lever 3.Separating brake sincere sub 1 and connecting lever 3 are all assemblied in self rotating shaft, and separating brake sincere sub 1 is arranged on separating brake sincere sub 1 near connecting lever 3 one end by rotating shaft.Connecting lever 3 is triangle, and connecting lever 3 one end are pushed down by closing magnet master part 2 under "on" position.
Described locking structure comprises the lock part that is located at described closing magnet master part one side
Closing magnet master part 2 is provided with lock part 5, and separating brake sincere sub 1 is provided with the locking face 4 engaging with lock part 5, and lock part 5 forms locking structure with locking face 4.Closing magnet master part 2 is provided with a side of lock part 5 near the rotating shaft of connecting lever 3.Therefore after locking structure engaging is pinned, closing magnet master part 2 can not turn clockwise towards connecting lever 3 directions.Sincere sub 1 of closing magnet master part 2 and separating brake are provided with back-moving spring 6.Separating brake sincere sub 1 can be that casting forms, and only has indivedual roughness of facing to have requirement, need to further process.Thereby saving raw material, reduce production costs.
In making process, the contact jaw of connecting lever 3 and closing magnet master part 2 is originally on the right side of closing magnet master part 2.Connecting lever 3 clockwise rotates the relative separating brake sincere sub 1 of promotion closing magnet master part 2 and rotates counterclockwise.After separating brake sincere sub 1 and connecting lever 3 disengage, back-moving spring 6 impels closing magnet master part 2 to reset, and lock part 5 fastens with locking face 4, as shown in Figure 1.At this moment no longer to connecting lever 3 application of forces, because described contact jaw is pushed down by closing magnet master part 2, separating brake holding device is under "on" position, and very stable.
In separating brake process, the sincere sub 1 first stressed rotation in the counterclockwise direction of separating brake, because locking structure has pinned closing magnet master part 2, it can not be rotated relative to separating brake sincere sub 1 along clockwise direction, so closing magnet master part 2 is also along with separating brake sincere sub 1 rotates counterclockwise around sincere sub 1 the rotating shaft of separating brake.After closing magnet master part 2 and connecting lever 3 disengage, connecting lever 3 can, along rotating counterclockwise 35 degree angles, cause separating brake.Separating brake sincere sub 1 also returns to original position afterwards with closing magnet master part 2, as shown in Figure 2.Now, separating brake holding device is in gate-dividing state.Under gate-dividing state, connecting lever 3 is positioned at a side that is provided with lock part 5.Like this, even if closing magnet master part 2 can not flexible rotating, can not hinder connecting lever 3 separating brakes yet.
By reference to the accompanying drawings the utility model has been carried out to exemplary description above; obviously the concrete realization of the utility model is not subject to the restrictions described above; as long as the various improvement that adopted method design of the present utility model and technical scheme to carry out; or directly apply to other occasions without improvement, all in protection range of the present utility model.
