Definitions
- the invention relates to a breaking chamber of a high-voltage low-voltage circuit breaker intensity.
- Document EP 0 306 382 describes a multi-pole circuit breaker with molded insulating housing containing a control mechanism coupled to a switching bar of so as to ensure the opening and closing of all the poles of the circuit breaker.
- Each pole has a fixed contact member, a movable contact member and a arc extinguishing chamber.
- the fixed contact member has a fixed conductive pad current supply bearing on the bottom of the housing, main fixed contacts and a fixed arcing contact.
- the fixed contact area is arranged in front socket. In others terms, it consists of a relatively straight metal bar, which does not impose a curved path with the current crossing it and consequently prohibits any effect electromagnetic loop on the arc emerging at the opening.
- the contact body mobile has a fixed conductive power supply range also supported on the bottom of the housing, and a contact system having a plurality of main contacts identical, distributed in two series of the same number on either side of an arcing contact mobile extending longitudinally along the center line of the pole.
- Arc contact made protruding towards the interior of the chamber and allows the arc to enter the chamber.
- the arc extinguishing chamber is arranged above the first range and includes lateral flanges supporting a stack of separators constituted by sheets metal for deionization of the arc, each sheet having a V-shaped notch. lower bow horn and a higher bow horn frame the stacking of sheets of the extinguishing chamber.
- the upper bow horn has two side legs which are folded down towards the fixed contacts and which partially seal the upper part of the entrance to the room.
- a lateral guide cheek arc In the contact separation zone in the extension of each of the two lateral flanges of the chamber, is a lateral guide cheek arc.
- the two cheeks project obliquely towards each other from the plane of the flange corresponding.
- the cheeks have a substantially trapezoidal shape and are located in the lower part of the room, near the fixed contact. They limit in the lower part access to the room, near the lower bow horn.
- the guide cheeks allow centering of the arc root along the horn lower arc.
- Such a chamber is particularly suitable for circuit breakers of high rating, around 3000 A, having to satisfy single-phase voltage cut-off tests relatively high, around 600 V with fairly low current, around 5 to 10 times the rated current of the circuit breaker.
- it is ill-suited to cutting very high fault currents, of the order of 100kA, at a medium high voltage 480V.
- the intensity of the breaking current is very high, the diameter of the section of the arc is important, so that the arc is almost instantaneous on the whole contact fingers and immediately occupies the entire available volume of the bedroom.
- the chamber is then subjected to very high pressure and to a very high temperature. high.
- the gas emission from the cheeks further contributes to increasing the pressure. Now the positioning of the cheeks and the upper bow horn helps to reduce the opening of entry into the chamber, hence a delay in balancing the pressures in the housing the device, which can cause it to explode.
- arc chamber for circuit breaker, described in the patent US 4,650,938, comprising dividers intended to be placed close contacts, and a pair of lateral flanges arranged on either side of a plane longitudinal median of the chamber to support the separators.
- Each flange has an elongated rib projecting toward the opposite flange.
- the two ribs extend over the entire height of the chamber, perpendicular to the dividers, and face each other. They are arranged between the separators and the contacts, so as to restrict the width of the chamber entrance opening evenly across the height of the room.
- the ribs change the gas flow in the chamber, and protect the part of the flanges supporting the separators of the hot gas flow.
- circuit breaker of this type requires that arrangements be made to facilitate the entry of the arc into the chamber, and in particular that the fixed contact is U-shaped under the lower surface of the chamber, in order to create an electromagnetic loop effect favoring the entry of the arch in the room.
- the invention therefore aims to improve the performance of a low multipole circuit breaker high caliber tension fitted with a higher bow horn. It aims in particular to allow the breaking of large diameter electric arcs generated by currents very high fault under medium voltages, avoiding the risk of explosion of the bedroom.
- the bow horns help to ensure the entry of the bow into the chamber as soon as the head of the main electric arc switches to the upper arc horn, even if the ranges of contact are of the front socket type, without electromagnetic loop effect on the arc.
- the dielectric screens allow to lengthen and bend the electric arc between the movable contact in the open position and the separators, so as to promote switching of the arc on the upper arc horn.
- Shrinking screens dielectric in the lower part of the chamber, near the fixed contact allows to obtain a wide opening of the entry into the room, which promotes the balance of pressures between the chamber and anterior volume of the pole. Indeed, a rapid rise in the pressure in the chamber would be harmful to the entry and maintenance of the arc in the chamber. In addition, it would be likely to cause the explosion of the room.
- the combination profiled dielectric shields and arc horns allow the elongation of the arc in the chamber while controlling the pressure there.
- the upper bow horn has a free end located at proximity of the movable contact member in the open position, and interposed between the separators and the movable contact member in the open position.
- the upper part of each lateral dielectric screen is interposed between the separators and the free end of the upper bow horn.
- the lateral dielectric screens are made up of a low gas-generating material, in particular a polytetrafluoroethylene or a polyamide 6-6 or 4-6 heavily loaded.
- the screens do not contribute to increasing the pressures in the bedroom.
- they do not generate a gas flow likely to obstruct the entry of the arc in the bedroom.
- each dielectric screen has an upper part and a lower part substantially narrower than the upper part. Alternatively, it is possible to completely eliminate the lower part.
- each dielectric screen has a front part, the front parts of the two dielectric screens laterally framing at least partially the contact area.
- the front parts of the screens act as protective shield of the side wall of the pole.
- a low-voltage multi-pole power circuit breaker 10 comprises a molded insulating housing 12 containing a type 14 control mechanism known, provided with a transverse switching bar 16 common to all of the poles, swiveling in bearings formed in the housing 12.
- Each pole has a fixed contact member 20, a movable contact member 22 and an extinguishing chamber arc 24 located near the fixed contact member 20.
- the fixed contact member 20 includes a current supply range 26 mounted in the bottom of the housing 12, partially under the arc extinguishing chamber 24.
- the body of fixed contact 20 further comprises two main contact strips 28 (FIG. 2) fixed directly to the current supply range 26 and a median arcing contact 30 which is arranged on a metal plate 32 projecting from the contact strips fixed 28.
- the metal plate 32 is fixed to the current supply range 26 in a intermediate zone between the bars 28 and the chamber 24. It extends inwards of chamber 24 by a conductive lower arc horn 34.
- the supply range of current 26, the bars 28, the arcing contact 30 and the arcing horn 34 consist of various conductive metallic materials, and have the same potential.
- Arc contact 30 and the bars 28 together constitute a contact zone 36 intended to ensure the electrical contact with the movable contact member 22.
- the movable contact member 22 comprises a fixed conductive supply path current 40, a support cage 42 pivotally mounted about an axis 44 fixed relative to the housing 12 and a plurality of main contact fingers 46 (Figure 3) placed on the side and on the other side of a middle arc contact finger 48.
- the contact fingers 46, 48 pivot around a common geometric axis 50, fixed relative to the cage 42, and are recalled to the fixed contact member by contact pressure springs 52.
- a connecting rod coupling 54 is used for coupling between the cage 42 of the movable contact member 22 and a crank 56 of the switching bar 16 of the mechanism 14.
- Each finger main 46 includes a contact pad 58, intended to ensure contact with the corresponding contact strip 28 of the fixed contact member 20 when the appliance is in the closed position shown in Figure 1, and a lug 60 protruding beyond from the contact pad to the extinguishing chamber 24.
- the arcing contact finger has a movable arcing contact 62 intended to ensure contact with the contact fixed arc 30 of the fixed contact member 20 when the device is in the closed position shown in Figure 1, as well as a lug 64 projecting beyond the patch of contact to the extinguishing chamber 24 and having a shape identical to that of the pins 60.
- the contact fingers 46, 48 are electrically connected to the current supply range 40 through braids 49.
- the extinguishing chamber 24 comprises two lateral flanges 68 of insulating material, which are parallel to the section plane of Figure 1 and located equidistant from both sides of it, so that the cutting plane constitutes a longitudinal geometric plane median 70 of room 24 and the pole.
- a rear wall 72 of gas exhaust is arranged at the rear of the chamber, perpendicular to the lateral flanges 68. This wall 72 has one or more orifices 74 for exhausting the breaking gases.
- a front opening 76 is arranged near the contact zone 36, opposite the rear wall 72.
- Separators 78 constituted by flat metal plates extend perpendicular to the median longitudinal plane 70 of the anterior opening 76 at the rear wall 72.
- the dividers 78 are arranged at a distance from each other so as to leave the possibility of gas circulation between the front opening 76 and the rear wall 72. They are supported laterally by the lateral flanges 68. Each plate 78 has an anterior edge 80 for capturing the electric arc which has approximately a concave U-shaped curved shape in the plane of the plate or in V with a narrower asymmetrical notch 82. Separators 78 are stacked so that the notches 82 are alternately on one side and the other side from room 24.
- the lower bow horn 34 intended to receive the root of the bow when the bow extends from the fixed arcing contact 30 towards the interior of the chamber 24, has a part rear 84 located inside the chamber, and an intermediate portion 85 connecting the part posterior to the fixed arcing contact 30.
- the width of the posterior part 84 that is to say its largest dimension measured along an axis perpendicular to the plane longitudinal median 70 of the chamber, is important while the intermediate part 85 constitutes a narrower section.
- the rear part 84 has two lateral surfaces constituting reception areas 86 for the root of an electric arc developing in room 24.
- the lower bow horn 34 is fixed on a bottom constituted by a plate of material insulator 90, in this case polyamide 6-6 loaded with 30% glass fiber.
- the part of the plate 90 not covered by the bow horn extends to the flanges 68 and the wall posterior 72. It has a periphery 92 forming a protruding shoulder in the chamber and flush with the periphery of the rear part 84 of the bow horn.
- An upper bow horn 96 intended to receive the head of the bow when it leaves the arcing contact finger 48, is constituted by a metal plate perpendicular to the plane longitudinal median 70, supported by the lateral flanges.
- the upper bow horn 96 is substantially parallel to the separators 78 in its rear part and comprises in its front part a flap 98 which partially closes the chamber in its part upper, and which is interposed between the anterior edges of the separators 78 located in the upper part of the room and the outside of the room.
- the flap 98 has a face 99 which, when the movable contact member is in the open position (dotted in the figure 1), is located in the immediate vicinity of the pins 60, 64 of the contact fingers 46, 48.
- Two lateral dielectric screens 100 placed symmetrically with respect to the plane longitudinal median, limit the anterior opening of the chamber.
- the screens dielectrics 100 consist of a plate of insulating material with little or no gas generation, preferably polytetrafluoroethylene (PTFE) or polyamide 6-6 or 4-6 strongly loaded, or a thermoset or a polyester.
- PTFE polytetrafluoroethylene
- Each dielectric screen has a flat front part located in the extension of the side walls of the chamber in outside of it, and a posterior part which curves towards the chamber and towards the plane median following the profile of the separators.
- the front parts of the two screens dielectric 100 form cheeks located on either side of the fixed contact strips and extending over a height sufficient for the contact pads 58 to be also located between the cheeks when the circuit breaker is open.
- each dielectric screen itself has an upper portion extending fairly deep towards the room, and a lower lower part.
- the ledge 102 dielectric shields 100 which faces the chamber 24 is oblique, and forms a indentation at entrance 76 of the room.
- 100 dielectric screens slightly reduce the width of the opening 76 of the chamber in its lower part nearby of the fixed contact member, and further reduce the width of the front opening 76 of the chamber in its upper part, near the arc horn upper 96.
- the upper part of the posterior part of the dielectric screens 100 is inserted between the flap 98 of the upper bow horn 96 and the dividers 78 located in the upper part of the room.
- the switching bar 16 In the closed position, the switching bar 16 is locked by the mechanism 14, and maintains the cage 42 in the position illustrated in FIG. 1.
- the springs 52 provide contact pressure between the pads 58 of the main contact fingers 46 and the contact bars 28, as well as between the contact 62 of the arcing contact finger 48 and the fixed arcing contact 30.
- a trigger causes the release of the mechanism 14 which causes the opening.
- the rotation of the switching shaft 16 rotates the cage 42 about its axis of rotation 44.
- the main contact fingers 46 pivot very slightly around the axis of rotation 50, in an anti-clockwise direction in Figure 1, under the effect of the contact pressure springs 52, while remaining in contact with the bars 28. Then they meet a stop of the cage 42, and are driven integrally with the cage 42 rotating in the direction clockwise around the axis of rotation 44, so that they separate from the bars 28.
- the movement of the arcing contact finger 48 is similar, but offset in time, due to the spatial offset between the bars 28 and the fixed arcing contact 30.
- the contact fingers 46, 48 are near the flap 98 of the upper bow horn, in the position shown in dashed in Figure 1.
- the bow head then switches to the upper bow horn 96 allowing a main arc to stretch between the upper and lower arc horns, while secondary arcs form in series with the main arc, between face 99 of the flap 98 and the pins 60, 64 of the contact fingers 46, 48.
- the upper part of the screens dielectric imposes a bypass path on the arc, so that the arc head main gradually migrates on the upper arc horn towards the bottom of the chamber.
- the arc, entering chamber 24, divides more or less in contact with the separators 78 in elementary arcs, each elementary arc constituting an electrical connection in series between two adjacent separators 78 or between each arc horn 34, 96 and the separator 78 facing him.
- the pressure rise in the chamber is not too great, thanks in particular to the significant width of the lower part of the entrance to the room, which allows balancing pressures throughout the pole.
- the choice of a low or no gas-generating material for constituting the dielectric screens also contributes not to raise the pressure in the bedroom.
- the arc In the absence of dielectric screens (curves "a"), the arc remains oblique at the entrance to the chamber, between the flap of the upper bow horn and the lower bow horn.
- the dividers located in the upper part of the chamber are completely unused.
- the pressure P A in the chamber is low.
- the arc voltage U A is not high enough to prevent re-ignition of the arc after the current has passed through zero. The cut has failed.
- the dielectric screens are not very gas-generating, so as to control the pressure rise in the room.
- the flap 98 of the upper bow horn which promotes the switching of the arc, can be omitted if the position reached by the movable contact fingers at the end of the opening is favorable for direct switching to the upper arc horn.
- the screens have a part front that acts as a shield between the contact area or arises the electric arc and the side walls of the pole which frame the contact area.
- This front part can be omitted if necessary, if the side walls of the pole framing the contact area have sufficient resistance to the arc.
