Definitions

  • the present invention relates generally to auxiliary trip units intended to be associated with circuit breakers, in particular molded case circuit breakers.
  • a conventional molded case circuit breaker generally comprises, inside a molded case, a circuit breaker control mechanism, a trip bar that can be moved so as to break the latching of the circuit breaker control mechanism and at least one main trigger intended to control a movement of the trigger bar. If the circuit breaker is multipolar, a number of main trip units can be provided, this number being equal to the number of poles of the circuit breaker.
  • any of the main trip devices of the circuit breaker detects an electrical condition which is greater than a predetermined threshold, for example if it detects an intensity of current flowing in the corresponding pole greater than a predetermined value, this main trip device starts operating to control a movement of the trip bar, this movement of the trip bar causing the breakage of the latching of the circuit breaker control mechanism, and this circuit breaker control mechanism thus causing the simultaneous interruption of the various current channels which correspond to the different poles of the multipole circuit breaker.
  • auxiliary trip device which is intended to be able to also cause the breakage of the latching of the circuit breaker control mechanism , and this independently of the operation of the main trigger or the main trip units included in the circuit breaker.
  • auxiliary trip device of a first type which permanently detects the presence or absence of a voltage at the circuit breaker and which is intended to cause the circuit breaker to trip when this voltage disappears or becomes below a predetermined threshold.
  • Such an auxiliary trigger of this first type which is a conventional auxiliary trigger, is commonly called "auxiliary trigger of the type triggered by lack of voltage".
  • auxiliary trip device of a second type which is intended to cause the circuit breaker to trip when an electric current greater than a predetermined level flows inside the auxiliary trip device.
  • auxiliary trigger of the second type which is a conventional auxiliary trigger, is commonly called "auxiliary trigger with release by current emission”.
  • circuit breakers have already been produced or proposed including or receiving auxiliary trip units which can either be auxiliary trip devices of the undervoltage type, or trip trip type auxiliary trip devices. It has also already been proposed to design an auxiliary trip device which can constitute either an auxiliary trip device of the undervoltage type, or an auxiliary trip device of the trip emission type.
  • Such an auxiliary trigger generally comprises a certain number of parts which are common to the two types of auxiliary triggers which it is desired to constitute.
  • other parts of the auxiliary trigger are specific to the auxiliary trigger of the undervoltage type and still other different parts are specific to the auxiliary trigger of the type triggered by current emission.
  • certain parts which are common to these two types of auxiliary releases must be mounted differently for the two types of auxiliary releases. The fact that a large number of parts are different between these two types of auxiliary trip units is a drawback because this involves a relatively high manufacturing cost and a relatively high mounting cost.
  • An object of the present invention is to provide an auxiliary trip unit for a molded case circuit breaker, this auxiliary trip unit which can constitute either an auxiliary trip device of the undervoltage type or an auxiliary trip device of the trip emission type, while almost all of the parts which constitute such an auxiliary trigger are identical for the two types of auxiliary triggers which can thus be arranged.
  • Another object of the present invention consists in proposing such an auxiliary trigger in which the trigger threshold of the auxiliary trigger is both precise and adjustable, this threshold possibly being different when the auxiliary trigger is of the first type or of the second type and this threshold adjustment which can be carried out independently when the auxiliary release is of the first type or of the second type.
  • an auxiliary trip device according to the present invention is indicated generally by the reference 1.
  • the auxiliary trip device 1 according to the invention is intended to come to couple with or come to be housed in a circuit breaker with a conventional molded case (not shown).
  • the auxiliary trigger 1 generally comprises a trigger housing 2 which is intended to support in a fixed or mobile manner most of the parts which together constitute the device.
  • An energy storage system generally consists of a pallet 4 which is pivotally mounted on the housing 2 at two joints 6 disposed on either side of the housing 2 and a spring 8 which is intended to accumulate energy to operate the paddle. In the example shown in Figure 1, there are in fact two springs 8 which are mounted in parallel and which act jointly.
  • the auxiliary trip device 1 comprises an electromechanical actuating device which includes a coil 10 which surrounds other parts of the device (not shown in FIG. 1 and which will be described in more detail in the following text).
  • the auxiliary trip device also comprises a terminal block 12 supporting two electrical terminals 14, 16 which are electrically connected to the coil 10 and which are intended to be connected to external electric wires (not shown). Most of the internal parts of the auxiliary release 1 are not visible in FIG. 1 and will be described below.
  • FIG. 2 shows in longitudinal section the auxiliary release of Figure 1 when it is mounted in a particular way to form an auxiliary release of the undervoltage type.
  • the auxiliary trigger 1 is shown in more detail.
  • the electromechanical actuation device mainly includes the coil 10 which surrounds a sheath 18 comprising a central hole 20 which passes right through it longitudinally, and in this sheath are arranged a fixed core 22, a movable core 24 defining with the fixed core an air gap 26, a pusher 28 rigidly connected to the movable core 24 and a first spring 30.
  • the pusher 28 is in the form of an elongated rod which is threaded through a central hole in the movable core 24 and which is fixed to the movable core by screwing.
  • a first end 32 of the pusher 28 protrudes slightly from the movable core 24 and the other opposite end 34 of the pusher 28 is relatively distant from the movable core 24, that is to say that a significant part of the pusher 28 extends ( to the right in FIG. 2) over a long distance outside the movable core 24 while another opposite part 32 extends for a short distance outside the movable core 24.
  • a compression spring 30 is arranged so as to surround the pusher 28 while the fixed core is disposed around this same part of pusher 28.
  • the fixed core 22 includes a longitudinal hole which passes through it so as to thus pass through the pusher 28 and so as to constitute, in a part of the fixed core 22, a housing 36 for the compression spring 30.
  • the fixed core 22 further includes at its central hole, a threaded portion 38 in which is fixed a stop piece 40 which can be adjusted axially by screwing it more or less into the threaded part 38.
  • the compression spring 30 bears on one side against an end face of the movable core 24, this face also constituting the air gap 26, and rests on the other side against an end face of the part abutment 40. It follows from this that the compression force of the spring 30 tends to separate the movable core 24 from the fixed core 22 and to cause the air gap 26 to take a maximum dimension.
  • the central hole 20 of the sleeve 18 comprises a first bore 42 which opens on a first end 44 of the sleeve, a second bore 46 which opens at a second opposite end 48 of the sleeve and a middle part 50 which has a smaller diameter that the diameter of the first bore 42 and that the diameter of the second bore 46, the diameters of the bores 42 and 46 being preferably equal.
  • This energy storage system comprises the pallet 4 which is pivotally mounted around the axis 6 and the second spring 8 which is used to accumulate energy in order to suddenly activate the pallet 4.
  • the second spring 8 has one end fixed to a fixed anchor piece 51 and its other end is fixed to an anchor part 52 of the pallet 4.
  • the pallet 4 comprises a hooking end 54 which is distant from the articulation 6.
  • This system energy storage further comprises the latch 55 which is pivotally mounted around the axis 56 and which is continuously pushed (counterclockwise in Figure 2) using 'a spring 57 which is wound around the hinge pin 6 and which is moored to the housing of the device by means of one of these branches 58 which come to bear permanently against a part of the anchoring part 51.
  • the latch 55 comprises a hooking part 60 which comes to cooperate with the hooking part 54 of the pallet 4, when this pallet 4 is in the armed position for which it is moved by pivoting (clockwise in FIG. 2) in the direction which strips the second spring 8.
  • the pallet 4 is intended to control a movement of a trigger bar (not shown) which is conventionally included in a conventional circuit breaker and which is itself intended to cause, in a conventional manner, the breaking of the attachment of a circuit breaker control mechanism itself included in a conventional circuit breaker.
  • the lock 55 is, in the armed position, hooked to the pallet 4 and is movable (by pivoting clockwise in FIG. 2) against the spring 57 in order to release its attachment to the pallet 4 so as to allow the pallet 4, due to the relaxation of the second spring 8, to move suddenly by pivoting in order to cause the displacement of the trip bar (not shown) of the circuit breaker (not shown).
  • the displacement of the latch 55 in the direction which causes it to disengage from the pallet 4 is obtained by an appropriate displacement of the pusher 28.
  • the end 32 of the pusher 28 constitutes an actuating part 32 of the pusher 28 and it is located opposite and at a short distance from an actuating part 62 of the latch 55.
  • the auxiliary trip device 1 When the auxiliary trip device 1 is armed, that is to say when it is in the position shown in the figure 2, the latch 55 is hooked to the pallet 4 and the latch 55 is in a pivoted position (anti-clockwise) so that its actuating part 62 is located a short distance from the part actuation 32 of the pusher 28. This small distance is hereinafter called "guard".
  • the pusher 28 in this armed position, the pusher 28 is in a rest position as shown in FIG. 2, and this rest position corresponds in fact to a position of the pusher 28 in which it is completely pushed (to the right) the fact that the coil 10 is constantly supplied with electric current and that this has the consequence that the movable core 24 is attracted against the fixed core 22 (that is to say that the air gap 26 is made minimum). If at any time, the current flowing in the coil 10 becomes below a predetermined threshold, that is to say if the voltage across said coil 10 becomes zero or less than a predetermined threshold, the force of compression of the first spring 30 becomes greater than the force of attraction of the movable core 24 towards the fixed core 22, and the pusher 28 then moves to the left in FIG.
  • a predetermined threshold that is to say if the voltage across said coil 10 becomes zero or less than a predetermined threshold
  • An essential characteristic of the invention resides in the fact that the second spring 8 can accumulate and release, during its movements during the operation of the auxiliary trip device 1, a mechanical energy greater than the mechanical energy which can be accumulated and released by the first spring 30 during its movements during the operation of the electromagnetic actuation device of this same auxiliary trip device 1.
  • Another characteristic of the present invention resides in the fact that the "guard” is provided between the actuating part 32 of the pusher 28 and the part corresponding actuation 62 of the latch 55, when the latch is attached to the pallet 4 and when the pusher 28 is normally stressed due to the normal excitation of the coil 10.
  • the auxiliary trigger of FIG. 2 which constitutes a trigger of the type of triggering by lack of voltage, can function correctly while the coil 10 is supplied with electric current under a very low electric power (for example low voltage and / or a weak current).
  • the coil 10 is used to create an electromechanical force which is just sufficient to overcome the compression force of the first spring 30.
  • This first spring 30 can have a very low compression force.
  • the compression force of the spring 30 must however be sufficient to be able to actuate the latch 55 so that the latter releases the pallet 4.
  • FIG. 4 represents a diagram showing the variations of the force of attraction of the movable core 24 towards the fixed core 22 as well as the variations of the pushing force of the pusher 28 against the actuating part 62 of the latch 55, this as a function from the position taken by the pusher 28.
  • position 0 corresponds to the position of the pusher 28 when the movable core 24 is completely attracted to the fixed core 22. It can be seen that as long as the voltage across the terminals of the coil 10 is greater than a predetermined threshold, the force of attraction of the movable core towards the fixed core for the minimum air gap is greater than the pushing force of the spring 30.
  • the point A of the graph corresponds to the tension threshold for which the attraction force is equal to the pushing force of the spring 30.
  • auxiliary trigger 1 which has already been described in relation to FIGS. 1 and 2 but which is mounted differently so as to constitute an auxiliary trigger of the type triggered by the emission of current.
  • the auxiliary trigger 1 of the type with triggering by emission of current as shown in FIG. 3 operates "backwards" from the trigger of FIG. 2 in the direction in which the auxiliary trigger of FIG. 3 is triggered, that is to say that is, unlocks the latch 55 when an electric current passing through the coil 10 becomes greater than a predetermined threshold.
  • the device can be improved by providing a bearing 64 (see both Figure 2 and Figure 3) which surrounds the movable core 24 and which is housed in the bore 42 or 46 of the sleeve 18.
  • This part 64 serves to support and guide the movable core 24 during its longitudinal displacement.
  • the mobile core 24 must have an external diameter smaller than the internal diameter of the narrowed part 50 in order to be able to be mounted, and it cannot therefore be directly guided by the bore 42 or 46.
