By virtue of the above technical scheme, the alternating-current high-voltage switch opening device has simple structure and operation, and is free of restraints in terms of operating distance and space when opening in a high-voltage switch cabinet with limited space, resulting in convenient operation.
Description
Technical field
The utility model belongs to a kind of high voltage switchgear, more specifically says, the utility model relates to a kind of ac high-voltage switch switching-off device.
Background technology
Indoor AC high voltage vacuum breaker is as indispensable major control in the electric power system and protection equipment, the reliability height, cut-offs that capacity is big, the time between overhauls(TBO) long, pollution-free, no explosion hazard, is fit to series of advantages such as frequent operation.The circuit breaker of wherein joining magneto mechanism has characteristics such as the mechanism kinematic accessory is few, transmission efficiency is high, stability is good, mechanical endurance is long, has clear superiority in every field such as power industry, industrial and mining enterprises, railway transportations.
The AC high voltage vacuum breaker of magneto mechanism be because design feature itself need dispose manual switching-off device, satisfy do not have under the control power supply situation yet can accessible separating brake specification requirement.
Existing magneto mechanism vacuum circuit-breaker manual switching-off device all adopts the handle rotary manipulation, adopts toggle, and the operating space that needs is big.When circuit breaker moves in switch cubicle, carry out manual brake separating, as not having under control power supply and the system failure situation, because operating space restriction and operator are far away apart from vacuum circuit-breaker in the cabinet, so when when manual brake separating, adopting the handle rotary manipulation, the operator is not easy to exert oneself, and operation easier is big.
The utility model content
Problem to be solved in the utility model provides a kind of ac high-voltage switch switching-off device, its objective is to make manual switching-off device not be subjected to operating distance and spatial limitation, is convenient to operation.
To achieve these goals, the technical scheme taked of the utility model is:
This ac high-voltage switch switching-off device provided by the utility model, comprise depression bar, first connecting lever and second connecting lever, described depression bar is plugged on first connecting lever, described first connecting lever is fixedly mounted on the circuit breaker frame by bearing pin, and described second connecting lever is fixedly mounted on the circuit breaker main shaft.
Be provided with the button spring at described first connecting lever and bearing pin junction.
On described circuit breaker frame, be provided with two spacer pins.
Adopt technique scheme, this ac high-voltage switch switching-off device is simple in structure, simple to operate, makes manual switching-off device not be subjected to the restriction in operating distance and space to come handled easily when operating in limited high-tension switch cabinet.
Description of drawings
Below expressed content of each width of cloth accompanying drawing of this specification and the mark among the figure are made brief description:

Embodiment
Contrast accompanying drawing below, by description to embodiment, to effect and operation principle, the manufacturing process of the mutual alignment between the shape of embodiment of the present utility model such as related each member, structure, the each several part and annexation, each several part and manipulate method etc., be described in further detail, inventive concept of the present utility model, technical scheme had more complete, accurate and deep understanding to help those skilled in the art.
The of the present utility model structure expressed as Fig. 1, this is a kind of ac high-voltage switch switching-off device, comprises depression bar 1, first connecting lever 5 and second connecting lever 6, described depression bar 1 is plugged on first connecting lever 5.
In order to solve the problem that exists at the described present known technology of this specification background technology part and to overcome its defective, realize making manual switching-off device not be subjected to operating distance and spatial limitation, be convenient to operation.The technical scheme that the utility model is taked is:
Shown in Fig. 1 to 2, this ac high-voltage switch switching-off device provided by the utility model, described first connecting lever 5 is fixedly mounted on the circuit breaker frame 2 by bearing pin 4, and described second connecting lever 6 is fixedly mounted on the circuit breaker main shaft 7.
Adopt technique scheme, circuit breaker is when "on" position, circuit breaker main shaft 7 drives second connecting lever 6 and is buckled in closing position by lock for circuit breaker simultaneously, when with depression bar 1 when pressing down, first connecting lever 5 clockwise rotates around bearing pin 4, when first connecting lever 5 contacts with second connecting lever 6, when the power of moulded rod 1 is greater than the snap close power of breaker closing hold mode instantly, second connecting lever 6 will rotate counterclockwise, second connecting lever 6 drives 7 rotations of circuit breaker main shaft simultaneously, is exactly that the circuit breaker main shaft 7 and second connecting lever 6 have broken away from the switch-on latching state like this, in case circuit breaker has broken away from the switch-on latching state, in circuit breaker, under the effect of mechanism, can finish the sub-switching operation process.
In the time of in circuit breaker is installed in switch cubicle, circuit breaker 10 is advanced to cabinet inside by the chassis car 11 of self configuration, and this moment, circuit breaker 10 range switch cabinet front panels 9 distances were far away, can operate depression bar 1 and can finish the manual brake separating operating process to just pressing down.
To shown in Figure 2, be provided with button spring 8 with bearing pin 4 junctions as Fig. 1 at described first connecting lever 5.
Adopt technique scheme, when with depression bar 1 when pressing down, first connecting lever 5 clockwise rotates around bearing pin 4, when finishing the separating brake process, first connecting lever 5 returns to the home position under the effect of button spring 8.
To shown in Figure 2, on described circuit breaker frame 2, be provided with two spacer pins 3 as Fig. 1.
Adopt technique scheme, on described circuit breaker frame 2, be provided with two spacer pins 3, can limit the rotational angle of first connecting lever 5.
The technical scheme that the utility model adopted compared with prior art, has tangible difference, possessed substantial characteristics, and obtained progress technically, be worth in industrial promotion and application, so, the utlity model has novelty, creativeness and practicality.
In conjunction with the accompanying drawings the utility model has been carried out exemplary description above; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technical scheme carry out; or design of the present utility model and technical scheme are directly applied to other occasion without improving, all within protection range of the present utility model.
