Definitions

the present invention relates to a thermal tripping device for an electrical protection device, said apparatus comprising a trigger lever articulated on a plate and being controlled by said tripping device to cause in the event of a fault the breakage of a mechanical connection causing the automatic tripping of a control mechanism of the circuit breaker, this tripping causing the opening of two respectively fixed and movable contacts, said thermal tripping device comprising a bimetallic adapted to cooperate with a drawer connected in an articulated manner by one of its ends at said lever so as to drive said spool in the direction of release during deformation of the bimetal strip due to an electric overload, said spool cooperating with an abutment fixed with respect to the housing of the apparatus and intended to partly guide the trajectory drawer when moving.
the tensile force exerted by the end of the thermal bimetallic strip on the drawer is oriented in a direction which is normal to the point of support of the bimetallic strip on the drawer. This direction changes when bimetallic bends under the thermal effect of an electric overload. It is then necessary that the change in the direction of the force remains below a maximum angle in order to return the drawer against its stop.
the trigger stroke of the drawer is not repetitive as is the trip time for a given current.
the document EP 0 962 952 describes a device according to the preamble of claim 1.
the present invention solves these problems and proposes a thermal tripping device for an electrical protection apparatus in which the tripping times are repetitive even in case of significant bimetallic deflection in order to improve the performance of the apparatus.
the subject of the present invention is a thermal tripping device for an electrical protection device, said device being characterized in that said bimetal strip comprises, at its end cooperating with the drawer, a ramp portion, said ramp being arranged so as to position the slide against the aforementioned abutment during the first phase of deformation of the bimetal, so that said stop then guiding said drawer during its movement.
the plane of the ramp portion forms with the longitudinal direction of the bimetal an angle ⁇ of about 10 °.
the aforementioned ramp portion is made by folding the end of the bimetal.
the aforesaid ramp portion is made by shearing a portion of the end of the bimetal then folding this portion to form a ramp.
said ramp is made via an insert attached to the end of the bimetallic strip.
the apparatus comprising an upper part comprising the control mechanism and a lower part comprising means for fixing the apparatus to a support surface, said ramp is made by folding down the apparatus of the end of the bimetallic strip, said end being directed towards the top of the apparatus, on the side of the bimetall opposite the drawer.
the apparatus comprising an upper part comprising the control mechanism and a lower part comprising means for fixing the the apparatus to a support surface, said ramp is made by folding down the end of the bimetal, the latter then being oriented towards the bottom of the apparatus and extending on the same side of the bimetallic strip as the drawer .
the invention also relates to an electrical protection device comprising a thermal tripping device comprising the previously mentioned features taken alone or in combination.
a miniature electric circuit breaker molded insulating housing D comprising, in a manner known per se, a pair of contacts 1.2 fixed and mobile, said movable contact 2 being carried by a contact arm actuated by a control mechanism M.
This control mechanism M comprises a joystick 3 for manual operation of the contacts coupled to a transmission link 4 to form a toggle joint, a support lever 5 of the contact arm articulated on the pivot of a rotary plate 6, an arranged breakable mechanical link between the plate 6 and the transmission rod 4, and a trigger bar 7 hinged to the plate 6 and controlled by an electromagnetic tripping device 8 and a thermal tripping device 9 to cause, in case of failure, the rupture the mechanical link, causing the trigger mechanism independently of the handle 3.
this thermal tripping device 9 comprises a bimetallic strip 10 traversed by the current, said bimetal being fixed by a 10a of its ends to the housing B, and cooperating at its opposite end 10b, with a slide 11 mechanically connected to the trigger bar 7.
the spool 11 is of bent shape and has an end 11a hingedly connected to the trigger bar 7 and a portion extending perpendicularly to the plane of the spool (not visible in this figure) and on which the bimetal 10 comes s' press to exert traction on said drawer 11.
This drawer is intended to be positioned on a stop 12 in the first phase of deformation of the bimetallic strip.
the end 10b of the bimetal intended to cooperate with the slide 11 comprises a ramp 13 formed by folding down said end, which extends towards the top of the apparatus in the direction of the control mechanism M.
said end of said bimetal has been sheared and a portion 14 of said end portion has been bent to form a ramp 15 extending downwardly from the apparatus, i.e. apparatus for attachment by fastening means F to a support surface, said ramp extending between the drawer and the main portion of the bimetal.
this ramp is formed by means of an insert 16 forming a ramp attached to the end of said bimetallic strip.
the angle formed between this ramp end portion 13 and the longitudinal direction D of the bimetal is about 10 °.
the thermal tripping device is a device according to the prior art.
the force F1 exerted on the slide 11 at the beginning of deflection of the bimetallic strip 10 moves the slide 11 away from its abutment 12. This is due to the fact that, in view of the large deflection of said bimetal strip, this bimetal 'more its function of positioning the drawer against the stop.
a ramp 13 has been formed at the end of the bimetal strip according to the embodiment illustrated in the drawings. figures 2 and 3 .
the force F2 exerted by the bimetal at the beginning of its deflection causes the slide 11 to the abutment 12.
an electrical protection device has been realized in which the drawer is biased towards its stop from the beginning of the deflection of the bimetallic strip.
the drawer is correctly positioned, before the bimetallic begins to move in the direction of tripping.
the positioning of the slide on its stop allows said stop to partially guide the slide during its movement.
the trajectory and the trigger stroke of the drawer are therefore repetitive as well as the tripping times for a given current, hence improving the performance of the device.
This improvement has the advantage of representing a low industrial cost, will not occupy the place of another component of the circuit breaker, and will not induce a profound change in the kinematic chain of the circuit breaker.
the invention applies to any protective equipment using a bimetallic strip, for example a motor protection circuit breaker, a motor contactor, etc.
