What people valued is: the starting drive 1 of circuit breaker can one after the other occupy a configuration in many configurations, comes the effect of the return spring of the effect of the state variation of electricity system (not shown) and electromagnet and actuator 10 is responded.

For example, on Fig. 8, the contact of circuit breaker is closed, and lever 5 is in the position of " height " and is in the right of center line, as shown in the figure.The second end 7 of lever 5 therefore just tightly with second surface 26 and second chimb 29 mutually and put, by means of this chimb, this cam 3, framework 13 and tooth bar 30 are positioned the right of center line.This configuration is called as the " RUN " position.

On Figure 10, as the response that the electricity system state is changed, for example to the response of over-current state in the electricity system, joystick 33 rotates in counter-clockwise direction, so that open these contacts.This has just driven tooth bar 31 to left side motion, thereby drive cam 3 rotates in the clockwise direction around axle 4.This combination and the axle 22 that slit 23 is coupled of rotating of cam 3 just makes framework 13 rotate in counter-clockwise direction around axle 14.This configuration is called as " tripping operation " position.

Then, as the response to the action of actuator 10, lever 5 is pulled down in slit 9, has therefore tangled second chimb 29 of second surface 26 and cam 3.This action causes that cam 3 does clockwise direction around axle 4 and rotate, thereby drives tooth bar 30 and move to the left side, as shown in the figure, the action bars 33 of circuit breaker is rotated more in counter-clockwise direction.Framework 13 rotates along counter-clockwise direction.This makes circuit breaker control device 1 reinitialize later at circuit breaker trip.This configuration is called as " reinitializing " position.This configuration is also referred to as " moving-stop " position, it represented control device 1 from the " RUN " position to " stopping " centre position of this control device 1 when move the position.

On Fig. 7, as the response to the action of the return spring of actuator 10, lever 5 is driven to move upward in slit 9, and this makes the left side that lever 5 is positioned at center line, as shown in the figure.The second end 7 of lever 5 therefore just tightly with second surface 26 and first chimb 28 mutually and put.The contact of circuit breaker thereby just opened.Framework 13 remains on " stopping " position.

On Fig. 9, as the response to the action of actuator 10, lever 5 is driven and is moved down in slit 9, causes that therefore cam 3 rotates in counter-clockwise direction, thereby drives tooth bar 30 as shown in the figure to left movement, makes the closing of contact of circuit breaker again.Framework 13 rotates along clockwise.

When the action of the return spring of actuator 10 drives lever 5 and moves upward in slit 9, lever 5, and camming 2 is just got back to the initial configuration of Fig. 8 again.Camming 2 is got back to lever 5 its initial configuration before not moving up again,

What people valued is: control device 1 can be by manually starting, so that be closed " RUN " position from the breaker contact point of Fig. 8, carries out the transition to " stopping " position of Fig. 7, and the contact of circuit breaker is opened.Specifically be, when control device 1 is in the " RUN " position of Fig. 8, " stopping " button 37 can be manually by by entering.This action makes cam 3 rotate along clockwise, and framework 13 is rotated along counter-clockwise direction, so when making lever 5 be positioned at the left side and close first chimb 28 of center line, the contact of opening circuit breaker.This just guides control device " stopping " position to Fig. 7.In order to get back to the " RUN " position of Fig. 8, just manually " RUN " button 38 is pressed down.This effect makes cam 3 rotate along counter-clockwise direction, thereby just makes lever 5 get back to a position on center line the right and near in second chimb 29, making the closing of contact of circuit breaker again.

In addition, when control device 1 was in the " RUN " position of Fig. 8 at first, circuit breaker trip also drove control device 1 " tripping operation " position in Figure 10.Control device 1 is reinitialized by the action of actuator 10 magnet, and is brought to " reinitializing " position of Fig. 9.Control device 1 just is in " stopping " position of Fig. 7 then by returning of actuator 10.In order to get back to the " RUN " position of Fig. 8, just and top the introduction, manually press " RUN " button 38.This action makes cam 3 rotate along counter-clockwise direction, thus make lever 5 come back to center line the right a position and near in second chimb 29, make the contact of circuit breaker closed again.

So, just and shown on Fig. 7 like that, allow these buttons and actuator just are locked on the part of swing position on the right of the cam.This locking process is finished by change over switch is moved to its primary importance, and second slide plate can be fixed on its primary importance to change over switch and can match with a padlock, can make this locking secure by means of this second slide plate.In the other position of cam, the user selects between the second and the 3rd position of change over switch, and first slide plate is forbidden moving to primary importance.

Obviously, top description is not restriction, and is to provide as pure illustrative example, within the scope of the invention, can carry out changes and improvements to it.
