  • the object of the invention is to provide an electromagnetic switching module provided with a switching chamber and single-switching switching poles with improved electromagnetic properties.
  • the switching poles always remain closed outside the switching operations and this is particularly effective because of the electromagnetic properties of these poles and the arrangement of the switching chamber.
  • the switching module according to the invention is characterized in that, for each pole, the movable contact holder comprises two parallel conductors in the form of loops joined to a terminal and that the two pieces of fixed contacts are in the form of loops and joined together at terminals.
  • the electromagnetic switching module according to the invention is intended to be associated with a multipolar electromagnetic switch device Ap which can be provided with a motor protection function, such as a contactor or a contactor-circuit breaker. It can be integrated, in association with devices such as Ap, in classic schemes such as: reverse direction, star-delta start, distribution, shifting.
  • the main switch device Ap houses, in a housing, polar current lines arranged between source terminals L1, L2, L3 connecting to the phases of the alternating network and charging terminals T1, T2, T3 that can connect to the module. switching circuit M.
  • Each current line has a switch or pole I1 or I2 or I3 controlled by a main electromagnet E whose coil B is supplied with electric current by two power terminals marked A1 and A2.
  • the switching module M is housed in a box Bo provided on the back of a fixing base P, substantially flat, for fixing it on a rail or a plate. It has source (power) terminals t1, t2, t3 connected directly to the downstream terminals T1, T2, T3 of the main apparatus AP and the output or load terminals (power) U, V, W of a part u, v, w on the other hand that are connected to the (x) motor (s).
  • the switching module M can be mounted directly under the apparatus Ap or it can be deported.
  • switching poles C1, C2, C3 of the single-breaking and bistable type are arranged on the current lines between the source terminals t1, t2, t3 and the output or load terminals. These poles C1, C2, C3 are actuated by a bistable electromagnet E1 provided with a coil Bb and their contacts are always alternately closed except during switching.
  • the module M does not have an arc extinguishing device and can not be operated under load.
  • the number of terminals t1, t2, t3 is equal to the number of terminals T1, T2, T3, the number of poles C1, C2, C3 itself being equal to or less than this number of terminals.
  • the poles C1, C2, C3 and the internal wiring Sc of the associated current lines perform a conventional motor control function: inverter, star-delta or distribution, low speed-high speed.
  • the wiring of the circuit of the power circuit of the module M depends on the control function performed by this module.
  • the source terminal t3 is connected directly to the charging terminal W.
  • the source terminals t1 and t2 are connected (direct) to the terminals charging U and V by the poles C1, C2 and after switching of these same poles (reverse operation), terminals V and U, which achieves the usual crossing phases.
  • the source terminals t1, t2, t3 are arranged on one side of the module while the charging terminals U, V, W (delta starting or first motor or high speed) and the charging terminals u, v, w (star start or second motor or small speed) are arranged on the opposite side.
  • the terminals U, V, W on the one hand, u, v, w on the other hand are offset relative to each other.
  • the electromagnet El of bistable type housed in the switching module M and actuating the movable contacts of the switching poles C1, C2, C3 is equipped with a permanent magnet so as to reduce the power consumption.
  • This electromagnet El is controlled by an internal control circuit Cc shown in Figure 10.
  • the movable magnetic part of the electromagnet El which has a reciprocating rectilinear movement maneuvers the switching poles C1, C2, C3 by a slider Ra.
  • the axis of displacement of this electromagnet is parallel to the plane of attachment Pf and to the terminals.
  • the switching module M is arranged so that the switching poles C1, C2, C3 and the associated power circuits and the pole control assembly formed by the electromagnet El and the control circuit Cc are offset. or spaced in a direction perpendicular to the rear face Pf for fixing the module and that the width L of the module is substantially equal to the width of the associated main apparatus Ap. The width L is therefore reduced when compared to conventional apparatus performing similar functions.
  • the switching poles C1, C2, C3 and the conductors Sc of the wiring diagram (inverter, etc.) are housed towards the rear, the electromagnet El and the associated control circuit Cc being housed towards the front.
  • Each switching pole C1 or C2 or C3 illustrated schematically in FIG. 6 is of the inverter type (contacts always closed) and is constituted by a mobile contact carrier Pc carrying two parallel conductors Cm1, Cm2 in the form of loops and carrying respectively the moving contacts. P1 and P2. These conductors are joined to a terminal t1, t2, t3.
  • the contact carrier Pc oscillates around a pin Ax and an axis A-A 'between two conductors Cf1, Cf2 carrying the fixed contacts P3 and P4.

  • the movable contact carrier Pc oscillates around the axis A-A ', from a first working position, closed contacts, to a second working position, closed contacts also.
  • This loop effect makes it possible to obtain a contact pressure proportional to the current flowing in the pole.
  • the poles are never operated under load, which makes it possible to reduce the nominal contact pressure, the size of the electromagnet being reduced.
  • the moving parts of the electromagnet actuate a slider Ra movable in translation parallel to the rear fixing plane Pf and acting on each pole spring Rp via a piece Pi.
  • the fixed conductors Cf1, Cf2 realize with extensions or complementary conductors terminating at the charging terminals (power) U, V, W etc, one of the control schemes Sc of the motor or engines. These extensions or complementary conductors are housed in the box Bo, on the side of the charging terminals.
  • the mobile conductors Cm1, Cm2 of the contact carrier PC are distant relative to each other, so that a magnetic core No is housed between them. This magnetic core No cooperates with counterplates Cp1, Cp2 fixed inside the switching chamber housing the pole.
  • the moving contact parts Cm1, Cm2 are connected by a flexible electrical connection Tr and a conductor such as Co3 to a source terminal such that t3.
  • the input and output terminals for control are arranged forward.
  • the input terminals A2, A1, A1 ', B1, B1' are intended to receive the motor control commands and the output terminals SA1, S21, S22 cooperate with the associated main apparatus Ap.

  • the coil Bb of the electromagnet E1 is fed so as to be biased in either direction.
  • This control can be performed by two auxiliary inverter contacts 1a and 1b actuated by the movable part of the bistable electromagnet E1 and associated with diodes 7a, 7b.
  • the switching module M may comprise other auxiliary contacts such as 3 and 6 also actuated by the moving part of the electromagnet El.
  • the terminals A1, A'1, B1, B'1 of the switching module M are connected on the one hand with the contacts Bp1 controlling the operation in the "one direction” and on the other hand with the contacts Bp2 controlling the operation in the "two direction”.
  • One-way operation is defined as one of the two modes of operation of the module, ie direct operation for the inverter or star for the star-delta.
  • the second mode is called "direction two" operation, ie the reverse or triangle operation.
  • the electromagnet E1 of the main apparatus Ap is powered via the ON / OFF switch MA, the contacts Bp1, Bp2 and 6.
  • the poles of power 11, 12 and 13 of the main apparatus Ap are in the operating position "direction one".
  • Switching switches such as C1, C2 of the switching module M are in the position corresponding to this operating mode "direction one" (these poles are always in the closed position).
  • the operator opens a contact Bp2 and closes the associated contact Bp2.
  • the opening of the contact interrupts the supply of the coil B of the main apparatus Ap.
  • the closing of the contact Bp2 causes the supply of the coil Bb of the module M which causes the commutation of the switching contacts such as C1, C2.
  • the auxiliary contacts of the module M switch and the current is sent on the electromagnet E of the main apparatus Ap so as to operate the power switches 11-13.
