Definitions
- the invention relates to a mechanical spring control for circuit breaker in a high or medium voltage network, comprising a toothed wheel rotated by a spring of a first position angular to a second angular position and a pinion cooperating with the gear wheel to move it from the second angular position towards the first angular position in order to tension said spring, said toothed wheel having a peripheral toothing consisting on the one hand of a primitive toothing integral with the wheel and on the other hand with a toothing part in the form of a retractable toothed segment, said primitive toothing being of constant pitch.
- a circuit breaker in a high or medium voltage network means switchgear for an electrical network whose voltage operating power is greater than 1 kV.
- the invention can firstly be applied to a mechanical control in which the toothed wheel is integral with a single drive shaft coupled to a movable contact of the circuit breaker so as to close the circuit breaker by the detent spring which is able to drive the wheel. It can also be applied to an order in which the toothed wheel is integral with a first shaft called a shaft which is coupled to the movable contact via a second tree says main tree, as is generally the case in latest generation controls for high voltage circuit breakers.
- the connection between the shaft (s) and a movable contact of the circuit breaker is not reversible, i.e. the interlocking spring can be re-tensioned by rotating the pinion after closing the circuit breaker without causing it to open.
- This pinion is driven by a electric motor to reset the control, and the gear wheel turns in the same direction when the interlocking spring relaxes and when it is tensioned by the engine.
- a ratchet is generally arranged opposite a cam linked in movement to the wheel toothed so that the cam comes to rest on this pawl when the wheel toothed reaches the first angular position.
- This ratchet is usually articulated so that its release releases the toothed wheel and triggers the closing of the circuit breaker by spring expansion.
- Stopping the engine by cutting off its power supply is not suitable for immobilizing the toothed wheel with sufficient precision because engine inertia delays this stop.
- Such an order therefore includes usually a mechanical device to disconnect the motor from the gear when it reaches the first angular position. Without such device, the forces generated by the inertia of the motor in the teeth and in the pawl would cause significant wear of the control which would quickly lead to its destruction.
- Patent document EP 0917168 contains a good number of elements components which can be used in a mechanical control according to the invention.
- the toothed wheel includes a plurality of teeth capable of slide towards the inside of the toothed wheel, these sliding teeth being located in an area of the gear wheel corresponding to the position of the pinion when the gear is in the first angular position.
- Each sliding tooth is able to retract by sliding radially at against its own return spring. More specifically, each sliding tooth has an asymmetrical profile with a tooth head forming an inclined plane, so that when they are meshed by the pinion, the sliding teeth retract under the effect of the pressing force that they undergo from the pinion, which has the effect of uncoupling mechanically the gear wheel motor.
- These sliding teeth are spaced a distance significantly greater than the pitch of the teeth for the rest of the toothed wheel, in order to facilitate re-engagement of the pinion during of the spring relaxation.
- the retractable teeth have a specific profile including a head tooth shaped inclined plane which further increases the manufacturing cost.
- the toothing of the toothed wheel comprises teeth arranged on a segment retractable
- the object of the invention is to remedy the drawbacks of the condition of the technique by proposing a more reliable system for a cost of reduced manufacturing.
- the subject of the invention is mechanical spring control for high voltage circuit breaker, comprising a gear wheel driven in rotation by a spring from a first angular position to a second position angular and a pinion cooperating with the toothed wheel to move it from the second angular position to the first angular position so tensioning said spring, said toothed wheel having a peripheral toothing consisting on the one hand of a primary toothing integral with the wheel and on the other part of a toothing in the form of a retractable toothed segment, said primitive toothing being of constant pitch, characterized in that said retractable segment includes at least four teeth spaced one by one of the same constant pitch as the pitch of said primitive toothing.
- the retractable tooth segment thus comprises a conventional toothing not requiring any special machining, which further reduces the cost of manufacture of the control according to the invention.
- the segment is articulated in the gear wheel by a first end, being retained by a return spring tending to keep it out.
- This return spring can advantageously consist of a bent V-shaped blade.
- the segment is naturally retracts when engaged by the pinion at the first end, so there is no need to provide mechanism for controlling the position of the retractable segment which simplifies the control according to the invention.
- the joint is located inside a circle of the same diameter as the diameter of base of the gear wheel.
- the articulation of the segment comprises an axis which is positioned at a distance from the base diameter between one and two times the distance between the base diameter and the pitch diameter.
- the segment shrinks in the thickness of the gear wheel between two plates forming flanges of the toothed wheel. So the gear wheel has a limited space, and the teeth can be produced by cutting the plates.
- the reset system of the engagement spring 4 of a mechanical control comprises a latching shaft 1, a large diameter gear 2 mounted on this shaft engagement, and a drive motor not shown coupled to the gear 2 via a pinion 3.
- the movable contact of the circuit breaker is coupled to the interlocking shaft via in particular of a main tree known per se and not shown.
- the engagement spring 4 is used for driving the shaft 1 to cause the circuit breaker to close.
- Spring 4 has a first end connected to a first cam 5 which is mounted in end of the interlocking shaft 1 while being integral with this shaft and a second end linked to the control frame. More specifically, the spring 4 has its first end linked to an anchor point 5 'on the first cam via a 4 'cable or a chain passing through a 4 "angle return pulley.
- the anchor point 5 'on the first cam 5 is eccentric with respect to the interlocking shaft 1, so that when the engagement shaft is in a first angular position shown in Figure 1, the spring 4 is tensioned and exerts a force tending to drive the interlocking shaft in the indirect direction IND in the figure. This first angular position is close to a top dead center position corresponding to maximum spring tension 4.
- the motor is mechanically decoupled from the wheel toothed when it reaches the first angular position thanks to the setting using a segment of retractable teeth.
- the peripheral toothing of the gear 2 consists on the one hand of a primitive toothing integral with the wheel and on the other hand a portion of teeth in the form of a segment retractable toothed 10.
- This segment is arranged at the periphery of the wheel toothed 2 in an area corresponding to the position of the pinion 3 when the gear is in the first angular position.
- This segment 10 can by example be slidably mounted relative to the gear 2 so as to be able to slide in a generally radial motion relative to to the interlocking shaft.
- the segment 10 retracts to uncouple the pinion 3. More particularly, when the segment 10 retracts, the teeth which it carries approach the engagement shaft to disengage the pinion 3 and the toothed wheel 2.
- the retractable segment 10 comprises at least four teeth spaced one by one with the same constant pitch as the pitch of the teeth primitive.
- the segment 10 When the segment 10 is in an extended position, its teeth are located in the continuity of the original toothing of the wheel tooth 2 to authorize a meshing of the pinion 3.
- the teeth of segment 10 are also normal and identical teeth to the teeth of the primary dentition.
- a minimum number of four teeth is necessary for a segment 10 in an order according to the invention.
- the teeth of segment 10 can be produced with a machine classic tool for machining gear teeth, which reduces significantly the manufacturing cost of the control according to the invention while by improving operational reliability.
- the segment could for example retract under the effect of a mechanism managing its radial position as a function of the angular position of the wheel toothed.
- a return spring 11 shown schematically in Figure 2 tends to maintain segment 10 in extended position, so that this segment 10 spontaneously retracts as soon as the pinion 3 meshes it, which will be detailed below.
- segment 10 has a first end fixed to the toothed wheel 2 by a joint 12 and its other end supported on the return spring 11 which is integral with the wheel toothed.
- the articulation 12 is produced by an axis fixed to the toothed wheel and around which the segment 10 can rotate.
- the return spring 11 is here a coil spring extending radially with one end supported on segment 10 and its other end resting on toothed wheel 2.
- the retractable segment 10 can be produced in one plastic material such as a polymer so as to form for example a unique piece made by molding and including two protrusions forming the axis of the joint 12.
- a spiral spring located at the axis of the joint 12 having one end connected to the segment and its other end connected to the toothed wheel is also possible without departing from the scope of the invention.
- a spring 11 whose straight parts of the V-shaped blade each has approximately the same length as the retractable segment 10 and form between them an angle of between 10 ° and 20 ° may be entirely suitable, as shown in FIG. 4.
- the segment 10 is thus able to retract by pivoting against the return spring 11. More particularly, when the segment is retracted forms a recess in the periphery of the toothed wheel 2: the teeth of the first end move globally in the radial direction of the gear 2 towards the interlocking shaft, while the teeth of the second end which are close to the joint move little, as shown in figure 7.
- the segment and the return spring can advantageously be mounted in the thickness of the gear wheel to reduce its size so that the segment retracts into the thickness of the gear wheel for reduce its size, as visible in FIG. 3 which is a view in partial section of the segment and of the return spring in a plane containing latch shaft 1.
- the toothed wheel 2 here comprises three steel plates 2A, 2B and 2C resting on each other.
- the central plate 2B includes a large recess at the retractable segment 10 and it is sandwiched between the two side plates which form sprocket flanges and include smaller recesses size in this area.
- the retractable segment is guided by the two side plates 2A and 2C between which it is free to slide radially.
- the axis of the joint 12 which crosses the segment 10 has each of its ends fixed to a side plate 2A, 2C.
- the recess of the central plate 2B in particular forms a abutment on which the second end of segment 10 is in support when it is extended.
- each plate has a small thickness which which allows the teeth to be produced by cutting each plate instead of achieve this toothing by machining in order to further reduce the costs of manufacture of the control according to the invention.
- the teeth that are each provided with plates on their periphery except for the segment area retractable constitute the toothing of the toothed wheel.
- the toothed wheel can also be carried out with a greater number of plates of so as to form a thicker toothing while making it by cutting instead of making it by machining.
- Figures 5 to 8 give a schematic representation of the operation of the rearming spring reset system 4 the command corresponding to the resetting of the spring then to the tripping of a circuit breaker by the control. During this operation the gear wheel turns in the indirect direction IND on the FIGS.
- FIG. 5 represents a part of the toothed wheel 2 when it is rotated in the indirect direction IND by the pinion 3 to reach its first angular position.
- the pinion 3 reaches the first end of the segment 10 being initially engaged in the teeth of this segment, which corresponds substantially to the position for which the first cam 5 comes to bear on the pawl 6.
- the pressing forces F 1 of the pinion 3 on the teeth of the segment 10 are carried by a substantially oblique axis A 1 which is positioned so that the articulation 12 is between this axis A 1 and the engagement shaft 1. More particularly, these pressing efforts F 1 are oriented from right to left in FIG. 6, in such a way that they tend to rotate the segment 10 in the indirect direction IND around the axis of the articulation 12 for that the segment retracts as soon as it is engaged by the pinion 3.
- the segment naturally retracts, this which mechanically uncouples the motor from the toothed wheel when the latter reaches the first angular position.
- the pinion 3 stops in a position any angle: it can be meshed in segment 10 which is then in the extended position; or disengaged with the segment which is then retracted as in figure 7.
- the drive of the pinion by the motor can be achieved through a clutch type system.
- the invention makes it possible to reduce these mechanical stresses so that a direct drive of the pinion by the motor generally does not drive premature wear of the pinion teeth and / or the retractable segment.
- the pinion 3 and the gear 2 spontaneously disengage when the wheel reaches the first position angular and spontaneously re-couple when the spring 4 relaxes.
- the articulation 12 of the segment 10 is located inside a circle with the same center as the wheel 2 and the same diameter as the base diameter D B of the teeth of the wheel 2, to further facilitate re-engagement. More particularly, during the relaxation of the spring 4, the pressing forces F 2 of the pinion 3 on the teeth of the segment 10 are carried by another axis A 2 also oblique. By positioning the articulation inside the base diameter D B , this other axis A 2 is located in such a way that the articulation 12 is located between the interlocking shaft and this other axis A 2 .
- the toothed wheel As the toothed wheel is here driving, these efforts F 2 are oriented from left to right in Figure 8, which tends to rotate the segment 10 in the direct direction DIR to bring out this segment and thus promote the re-coupling of the pinion 3 with the toothing of the segment. Thus, the risk of pinion 3 jamming is further minimized, which significantly improves the operating safety of the control.
- the basic diameter of the teeth corresponds to the diameter of a circle centered on the wheel 2 and tangent to the axis A 2 as well as to the axis A 1 .
- the axis of the articulation 12 of the segment 10 is substantially distant from the base diameter D B of the toothed wheel 2 so that the displacement of the teeth of the retractable segment 10 takes place in an oblique direction relative to the radial direction of the toothed wheel 2.
- the closer the axis of the joint 12 is to the base diameter D B the more the displacement of the teeth of the retractable segment 10 is radial; and the farther this axis is from the base diameter D B , the more this displacement takes place with a non-negligible tangential component along an axis tangential to the toothed wheel 2.
- the tangential component of the displacement of the teeth of the retractable segment 10 promotes an anticipated engagement of the pinion 3 of the motor, that is to say an engagement in a situation for which the segment 10 is not yet fully extended while the gear 2 begins to drive the pinion 3 in rotation.
- the continuation of the meshing spontaneously produces the exit from segment 10, as indicated above.
- the pressing forces F 2 due to the meshing are thus reduced during the exit from the segment 10, compared to a system where the axis of the joint 12 would be closer to the base diameter D B of the toothed wheel.
- the variation in these pressing forces is also less abrupt during this phase of the start of engagement.
- the positioning of the axis of the articulation 12 at a certain distance from the base diameter D B , as well as the arrangement of the teeth of the retractable segment 10 spaced from each other by the same constant pitch as on the toothed wheel 2, contribute to improving the life of an order according to the invention and also allows the use of a plastic material such as a polymer to produce the retractable segment without risk of premature wear of the teeth of the segment.
- the control according to the invention may also include a switch electric motor supply intended to manage the motor supply depending on the angular position of the gear.
- the command also includes a second cam 7 integral with the interlocking shaft and which cooperates with a lever control 8, as shown in figure 1.
- This control lever 8 is mounted rotatable at one end and at its second end held in support on the contour of the second cam 7 by an elastic element 8 'which here is a coil spring.
- This control lever is linked in movement to an electrical switch (not shown) via three rods 9A, 9B, 9C so as to control the power supply to the engine.
- the contour of the second cam 7 forms a spiral arc centered on the interlocking shaft which closes on itself by a recess.
