Specific embodiment
The invention mainly comprises：Vacuum tube 1, support plate 2, bearing 3, support 4, pull bar 5, bearing pin 6, lever 7, axle 8,
Bar 9, roller 10, control rail 11, boss 12.Shunting switch every mutually at least include 1,2 pull bars 5 of 2 vacuum tubes,
8,2 poles of 7,2 axles of 6,2 levers of 2 bearing pins, 10,1 control rail 11 of 9,4 rollers, n-1 boss 12,
Boss 12 is arranged symmetrically on control rail 11 two sides；Vacuum tube 1 is arranged on support plate 2, and support plate 2 and support 4 are arranged on bearing
On 3；The lever of vacuum tube 1 is connected with pull bar 5, and lever 7 and pole 9 use axle 8 hinged, and lever 7, pole 9 one end are respectively
Equipped with roller 10, the another location of lever 7 is contacted with pull bar 5, and the another location bearing pin 6 of pole 9 is connected with support 4；
Support 4 is provided with stopping means 4.1,4.2, to limit the transverse shifting of lever 7 and pole 9；Bearing 3 is arranged on driving machine
On structure, control rail 11, n static contact 16, n >=2, conductor rail 13 are provided with frame 14.
For the ease of analyzing the elongated central line setting bearing pin 6 on the axis of vacuum tube 1, axle 8 is located at lever 7 and pole 9
Centre position, size of the present invention is the same, vacuum tube is opened in the case of identical, the height of boss 12 for vacuum tube open away from
2/3, because the height of boss 12 is less, therefore reduce the cost of product；If vacuum tube is opened away from identical with boss height,
Then the distance of axle 8 to the roller 10 on lever 7 and pole 9 is about with the ratio of distances constant of axle 8 to bearing pin 6 and axle 8 to pull bar 5
1.618, because lever powered phase is more than driven section, and the power acting on boss is not more than the self-closing power of vacuum tube, drive mechanism
Just vacuum tube can be disconnected with less driving force, impulsive force during production switch circuit is relatively small, therefore extends correlated parts
Life-span, increased the reliability of product；Again due to acting on the force direction on boss 12 on the contrary, a part of can cancelling out each other
Active force, makes the deformation tendency of control rail reduce, and reliability improves.Control rail 11 and conductor rail 13 can unify as solid memder,
To reduce the cost of product.
Main contact 15 on support plate 2 is electrically connected with output contact 18 by a vacuum tube, transition contact 17 passes through other one
Vacuum tube and transition resistance R are electrically connected with output contact 18；Output contact 18 is contacted with conductor rail 13；It is connected in drive mechanism
During switching circuit instruction action drive bearing 3 move (straight line or circular motion), make roller 10 by setup program with control rail 11
On boss 12 be contacting and separating, and then manipulate corresponding vacuum tube press set program opening and closing, and with corresponding active contact
15th, secondary moving contact 17 cooperation is allowed to be contacting and separating by the program setting with static contact 16 successively, makes circuit without interruption from one
Individual operating position (as 162 positions) is transformed into another operating position (as 163 positions), realizes in the case of not power-off bringing onto load
Circuit conversion, the output voltage of adjustment transformator, control power supply quality, the electricity consumption meeting user requires.Due to each static contact
Between there is potential difference, therefore use the short circuit current in transition resistance R limiting circuit transformation process.
The basic principles, principal features and advantages of the present invention have been shown and described above, the present invention is not restricted to the described embodiments,
On the premise of without departing from its general principles, the present invention also has multiple technologies scheme, and these technical schemes fall within the present invention
Claimed scope.
