Definitions

  • the invention relates to a method for adjusting a bimetal thermal trip device, in particular for an electric circuit breaker, consisting in positioning the bimetallic strip relative to a setting pin for a trip bar, following a passage of a current setting higher than that of the nominal current.
  • the factory setting has the role of minimizing the influence of these parameters, and consists of freezing the relative positions of the bimetallic strip relative to the trigger base.
  • a known method of factory setting is to pass a control current of 31n for a predetermined fixed time. An adjustment screw then deforms the foot of the bimetallic strip to trip the circuit breaker.
  • Another known method uses a shim, which after passage of the current for a fixed time interval, is made integral with the bar by means of an adhesive sensitive to ultra-violet radiation.
  • the polymerization of the adhesive lasts several seconds, during which period it is essential to immobilize the position of the bimetallic strip relative to the trigger bar.
  • the time of such an adjustment cycle is very long, which is a drawback when the adjustment is made on an automatic production line.
  • fusible material for example tin solder
  • control of the initial position of the bimetallic strip is based exclusively on the passage of the current for a given time.
  • a first object of the invention consists in improving the factory setting process of a thermal trip device in order to overcome all the factors of external influence or of construction.
  • the setting of the adjustment pin in the orifice can be carried out by laser welding carried out simultaneously on all the poles.
  • the control implemented by this process is based on the temperature, which reacts directly on the deflection of the bimetallic strip.
  • Laser welding takes place almost instantaneously when the pin is in its optimum position. Laser welding makes it possible to work on the fly, which is favorable for reducing the time of the adjustment cycle. Factory setting can be easily achieved automatically at the end of the production chain.
  • a servo device controlled by the temperature of the bimetallic strip to modify the setting of a screw for positioning the bar, so as to involve triggering for said second value of the temperature. After adjustment, the screw is locked in its support.
  • a second object of the invention consists in producing an adjustment device for implementing the method.
  • the device according to the invention is defined in claim 8.
  • the measurement of the temperature of the bimetallic strip takes place in real time by means of an infrared pyrometer coupled to an electronic circuit of a programmable controller, for controlling a laser and the servo device for the bar positioning screw.
  • the electronic circuit comprises control means actuated by the pyrometer output signal, compared to a first and a second reference signal S1, S2, the crossing of which is effected at times t2 and t4 when the temperature of the bimetallic strip reaches respectively the first and second values.
  • Figure 1 shows a schematic view of the implementation of the adjustment method according to the invention.
  • FIG. 2 represents the diagram of the temperature of the bimetallic strip as a function of time during a thermal adjustment cycle.
  • Figure 3 illustrates a partial view of Figure 1 of an alternative embodiment.
  • Figure 4 shows an enlarged view of part of Figure 3, after laser welding.
  • a thermal trip device 10 of a multipole circuit breaker comprises in each pole a bimetallic strip 12 associated with a driver 14 in which the current flows.
  • a cap 15 provided at the end of the bimetallic strip 12 is capable of cooperating with a trigger bar 16 mounted with limited rotation about an axis 18.
  • the insulating bar 16 rotates clockwise as indicated by the arrow F3, and causes the unlocking of the control mechanism (not shown) causing the opening of the contacts of the circuit breaker.
  • the bar 16 comprises a first attachment arm 20 cooperating with the latching lock (not shown), and a second positioning arm 22 equipped with an adjustment pin 24, which comes into engagement with the end 15 of the bimetallic strip 12.
  • the adjustment pin 24 When mounting the circuit breaker, the adjustment pin 24 is slidably inserted into a guide tube 26 secured to the second arm 22 of the bar 16.
  • the tube 26 and the pin 24, made of metallic material, for example steel , are separated from each other by a minimum clearance.
  • the axial length of the pin 24 is greater than that of the tube 26, which projects from the two lateral sides of the second arm 22.
  • a factory setting consists of freezing the positioning of the bimetallic strip 12 relative to the triggering members when the adjustment pin 24 reaches an optimum position.
  • the pin 24 is then immobilized in the tube 26 by means of the method according to the invention.
  • the method for adjusting the thermal trip device 10 is as follows:
  • an IR adjustment current is injected into the pole, having an intensity greater than the nominal current In, for example 3 to 5 In.
  • the passage of the IR adjustment current through the driver 14 causes the foot of the bimetallic strip 12, followed by the deflection of the end 15 in the direction of arrow F1.
  • the movement of the bimetallic strip 12 pushes the pin 24 inside the tube 26 in the direction of the arrow F2, while the trigger bar 16 and the tube 26 remain stationary.
  • an infrared pyrometer 28 measures in real time the temperature of the base of the bimetallic strip 12 through a hole 30 in the driver 14.
  • the pyrometer 28 compares the measured temperature to a first reference threshold S1 stored in an electronic circuit 32, in particular of a laser control automaton 34 and a servo device 36.
  • a screw 38 for adjusting the transverse position of the bar 16 is automatically controlled by the device enslavement 36.
  • the bimetallic strip 12 reaches the temperature a1 corresponding to the value of the first reference threshold S1.
  • the electronic circuit 32 controls the excitation of the laser 34, which sends a pulsed laser beam 40 towards the tube 26 (arrow p).
  • the impact of the laser beam 40 on the outer surface of the tube 26 causes a local fusion of the metal, causing the tube 40 and the pin 24 to be welded. This results in immobilization in translation of the adjustment pin 24 inside the tube. 26.
  • the adjustment current IR is maintained beyond the time t2, and continues to heat the bimetallic strip 12.
  • the blocking of the pin 24 generates an effect of bracing of the bimetallic strip 12, which results in a rotational movement of the bar 16 in a clockwise direction (arrow F3).
  • the pyrometer 28 compares the temperature of the bimetallic strip 12 with a second reference threshold S2, and the electronic circuit 32 verifies that the triggering action occurs at time t4 (point B, FIG. 2) and at temperature a2, called temperature of trigger.
  • the tripping temperature a2 is displayed on a display device 42 integrated in the control console. Note that the IR adjustment current is maintained until tripping, with reading of the tripping temperature a2.
  • the electronic circuit 32 is capable of involving the servo device 36 of the centralized adjustment screw 38 of the trip device. Commissioning of the servo device 36 takes place at time t3 (point C), slightly earlier than tripping time t4.
  • This method of adjusting the thermal trip device 10 is based on the temperature of the bimetallic strip 12, and not on the current.
  • a simple modification of the software of the electronic circuit 32 makes it possible to opt for a solution with or without the intervention of the control device 36.
  • the reduced time of the adjustment cycle allows direct adjustment of the thermal release at the end of the chain automatic manufacturing.
  • the steel adjustment pin 24 is inserted directly into a bore 46 of the insulating arm 22 of the bar 16.
  • the laser beam 40 bombards the pin 24 through an orthogonal orifice 48 made in the material plastic.
  • the molten metal is forced back towards the orifice 48 to form a stop 50 in rotation and in translation of the pin 24.
  • the thermal adjustment method according to Figures 1 to 4 is also valid for a bimetallic strip with direct heating.
  • the circuit breaker is advantageously positioned so that the pin 24 is directed vertically downward by bearing on the end 15 of the bimetallic strip 12 by gravity effect.
  • the insulating case 54 of the circuit breaker has a hole 56 opposite the bimetallic strip 12 of each pole to allow the infrared beam of the pyrometer 28 to pass.
