Description
Technical field
The present invention relates to the three position mechanisms of high-voltage switch gear, are a kind of operating mechanisms that three station output shafts are arbitrarily arranged.
Background technique
High-voltage switch gear or high-voltage circuitbreaker, can not only cut off or the no-load current in closed high voltage circuit and negative
Charged current, and overload electric current and short circuit current are cut off by the effect of relay protection when system jam,
It has quite perfect arc extinguishing structure and enough cutout abilities.Control high-voltage switch gear is related generally to during its actuating to close
Three lock, separating brake, ground connection stations when that is, operating mechanism is in closing position, not can be carried out ground connection operation, are in earthing position
When, then it not can be carried out closing operation；To guarantee the safety of high-voltage switch operating mechanism, prevent faulty operation from leading to safe thing
Therefore occur.But in high-voltage switch gear three position mechanism presently, there are greatest problem be operating mechanism and switchgear matching problem,
That is output interface is not on, and sometimes for interface to upper, the volumetric spaces of operating mechanism have been more than the offer space of switchgear, are had
When mechanism can arrange in the space of setting, but output interface is not on, if it is desired to meet two above problem,
Unique approach is only again switchgear " amount body " design organization, and such result causes some unnecessary designs and part
The wasting of resources increases manufacturing cost.
Summary of the invention
To overcome above-mentioned deficiency, the purpose of the present invention is provide a kind of behaviour that three station output shafts are arbitrarily arranged to this field
Motivation structure, makes that it solves in existing similar high-voltage switch gear product the output interface of switchgear and the output shaft of operating mechanism is more difficult matches
The technical issues of clock synchronization more difficult installation and adjustment structure.The purpose is to what is be achieved through the following technical solutions.
A kind of operating mechanism that three station output shafts is arbitrarily arranged, the operating mechanism include output shaft, back plate, the back plate
Side be equipped with output shaft；Its designing points is that the side of the output shaft passes sequentially through output toggle arm, connection sheet, clone's output
Axis connecting lever and clone's output axis connection, clone's output shaft stretch out switchgear, and clone output shaft and be set to switchgear, clone's output
Axis drives output shaft rotation by clone's output shaft connecting lever, connection sheet, output toggle arm transmitting.To without changing switchgear
Output interface will clone output shaft stretching and be installed on the output interface of switchgear, defeated by output toggle arm, connection sheet, clone
The output of output shaft to switchgear output interface can be realized in shaft connecting lever, clone's output shaft, to facilitate the operating mechanism
In the handling and maintenance of switchgear and the actuating installation of the operating mechanism output shaft.
The output shaft, output toggle arm, connection sheet, clone's output shaft connecting lever, the connected parallelogram of clone's output shaft
Structure, output toggle arm are identical as clone's shape size of output shaft connecting lever.Above structure convenient for output shaft to clone output shaft it
Between power transmitting, to keep the actuating of the operating mechanism more stable.
The outer diameter of clone's output shaft is equipped with bearing, and clone's output shaft is equipped with flat key face.Above structure is convenient for actuating hand
The connection of handle and clone's output shaft, and the rotation of clone's output shaft.
At least provided with adjustment hole between the mounting hole at the connection sheet both ends.Above-mentioned adjustment hole is also used as mounting hole to use,
Consequently facilitating according to required connection leaf length, to install connection sheet both ends and output toggle arm, the connection position for cloning output toggle arm
It sets.
The connection sheet is equipped with connection sheet described at least one.The connecting rod being made of more connection sheets, as long as passing through power
Transmitting meets the purpose that clone's output shaft drives output shaft, and the connected link mechanism of more connection sheets also can be used.
According to above structure feature, the technical characteristic of application method is: the energy of the output shaft by output toggle arm,
Connection sheet, clone's output toggle arm are transmitted to clone's output shaft, and output toggle arm, connection sheet are cloned between output shaft connecting lever by flat
The synchronous transmitting of row quadrilateral structure, clone's output shaft are set to the output interface of switchgear.I.e. by output toggle arm, connection sheet,
Clone's output shaft connecting lever realizes the transmitting of output shaft to power between clone's output shaft.
The configuration of the present invention is simple, rationally, linkage, transmission effect are good, and manufacturing cost and improving cost are low for design；It is suitable for
Connect use with the pairing of switchgear output interface for three station output shafts in high-voltage switch gear, ex hoc genus anne the structure of product change
Into.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
Figure number and title: 1, output shaft, 2, back plate, 3, connection sheet, 4, output toggle arm, 5, clone output shaft, 6, gram
Grand output shaft connecting lever.
Specific embodiment
Now in conjunction with attached drawing, structure of the invention and use are further described.As shown in Figure 1, the operating mechanism includes defeated
The side of shaft 1, back plate 2, connection sheet 3, output toggle arm 4, back plate is equipped with output shaft；The side of output shaft passes sequentially through output and turns
Arm, connection sheet, clone's output shaft connecting lever 6 are connect with clone's output shaft 5, and clone's output shaft stretches out switchgear, and clones output shaft
It is set to switchgear, the outer diameter for cloning output shaft is equipped with bearing, and clone's output shaft is equipped with flat key face.Output shaft, output toggle arm, company
Contact pin, clone's output shaft connecting lever, the connected parallelogram structure of clone's output shaft, output toggle arm and clone's output shaft connecting lever
Shape size is identical, and clone's output shaft drives output shaft rotation by clone's output shaft connecting lever, connection sheet, output toggle arm transmitting,
Above-mentioned output shaft is true output shaft.
The operating mechanism only need to arrange one piece of back plate 2 from structure again, this back plate 2 one effects will be as switchgear
Mounting plate, another effect are exactly the arrangement of transition output shaft, and the true output shaft of the operating mechanism itself is made to clone one again
The output interface deallocation of virtual output shaft and switchgear, has reached the principle of an interworking, and the repetition for reducing similar mechanism is set
Meter, greatly improves a kind of suitability of product, reduces manufacturing cost.The operating principle of the operating mechanism is as follows: when output shaft 1
By the transmitting of spring energy, outwardly output angle and energy, this output shaft 1 is due to this body structure of the operating mechanism at this time
The reason of, the output shaft 1 of arrangement is different surely to connect output interface with the input shaft of switchgear.But the energy of output shaft 1 at this time
It passes on clone's output shaft 5 near it, this clone's output shaft 5 is depending on 1 position of output shaft of switchgear
, therefore there is no problem to output interface, in the state that condition has been provided with, how by the energy of output shaft 1 completely
It is transmitted on clone's output shaft 5.The core point of the operating mechanism is exactly to pass through two connecting levers (output toggle arm 4 and clone's output shaft
Connecting lever 6) by the synchronous transmitting of connection sheet 3, it is exactly parallelogram sturcutre, is theoretically the mode for most efficiently transmitting energy.
Using same principle, any one output interface that clone's output shaft 5 is arranged into client's switchgear is corresponding to it.
