Definitions
- the present invention relates to an electromagnetic switching module multipole connecting by source terminals to a switch device main multipolar electromagnetic and by charging terminals to at least one motor and having, between these terminals, several power current lines provided of switching poles with alternately closed contacts always controlled by a switching electromagnet controlled by an electrical control circuit.
- the object of the invention is to provide a switching module which realizes integrated motor control function (reverse direction, start star-triangle, etc.) with a small width, substantially equal to the width of the contactor or standard electrical equipment with which it is paired to perform said function.
- This module therefore has a reduced width. Furthermore it is protected by the device associated with it and mounted upstream.
- the switching module according to the invention is characterized in that the poles and the current lines are arranged to perform a control function of motor such as reversing, star-delta starting or distribution function and that the pole control assembly formed by the switching electromagnet and the electrical control circuit is offset from the switching poles and current paths in a direction perpendicular to the rear fixing surface of the module so that the width of the module is reduced and substantially equal to that of the main associated device.
- a control function of motor such as reversing, star-delta starting or distribution function
- the electromagnetic switching module according to the invention is intended to be associated with an electromagnetic switch device multipolar Ap which can be provided with a motor protection function, of the type contactor or contactor-circuit breaker. It can be integrated, in association with devices such as Ap, in conventional schemes such as: reversal of direction of travel, star-delta start, distribution, gear change.
- the main switch device Ap houses, in a box, current lines poles arranged between source terminals L1, L2, L3 connecting to the phases of the AC network and T1, T2, T3 charging stations that can be connected to the switching 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 current electric by two supply terminals marked A1 and A2.
- the switching module M is housed in a box Bo provided at the rear with a fixing base P, substantially flat, allowing it to be fixed on a rail or a plate. It has source (power) terminals t1, t2, t3 which connect directly to the downstream terminals T1, T2, T3 of the main AP device and of the output or load terminals (power) U, V, W on the one hand u, v, w on the other hand which are connected to the motor (s).
- the switching module M can be mounted directly under the Ap device or it can be deported.
- switching poles C1, C2, C3 of the type to simple and bistable break. These poles C1, C2, C3 are actuated by an electromagnet bistable El provided with a coil Bb and their contacts are always alternately closed except during switching. Module M does not have a fire extinguisher arc and therefore cannot be operated under load.
- the number of terminals t1, t2, t3 is equal the number of terminals T1, T2, T3, the number of poles C1, C2, C3 being itself equal or less than this number of terminals.
- Poles C1, C2, C3 and the internal wiring Sc of the associated current lines perform a conventional motor control function: inverter, star-triangle or distribution, low speed - high speed.
- the wiring of the power circuit of the module M depends on the control function performed by this module.
- the source terminal t3 is directly connected to the charging terminal W.
- source terminals t1 and t2 are connected (direct operation) to the load terminals U and V by the poles C1, C2 and after switching of these same poles (reverse operation), at terminals V and U, which achieves the usual phase crossing.
- the source terminals t1, t2, t3 are arranged on one side of the module while the charging stations U, V, W (starting in triangle or first motor or high speed) and the charging stations u, v, w (star or second start motor or low 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 from each other.
- the bistable type electromagnet El housed in the switching module M and actuating the movable contacts of the switching poles C1, C2, C3 is equipped with a permanent magnet to reduce energy consumption.
- This electromagnet El is controlled by an internal control circuit Cc illustrated in Figure 10.
- the part moving magnetic of the electromagnet El which has an alternating rectilinear movement operates the switching poles C1, C2, C3 by a slide Ra.
- the axis of movement of this electromagnet is parallel to the fixing plane Pf and to terminals.
- the switching module M is arranged so that the poles of switching C1, C2, C3 and the associated power circuits and that all of control of the poles 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 the width L of the module is substantially equal to the width of the device main associate AP.
- the width L is therefore reduced if it is compared to usual devices performing similar functions.
- the switching poles C1, C2, C3 and the Sc conductors of the wiring diagram (inverter, etc.) are housed towards the rear, the electromagnet El and the associated control circuit Cc being housed forward.
- Each switching pole C1 or C2 or C3 illustrated schematically in the figure 6 is of the reversing type (contacts always closed) and consists of a contact holder mobile Pc carrying two parallel conductors Cm1, Cm2 in the form of loops and carrying respectively the movable contacts P1 and P2. These conductors are assembled at a terminal t1, t2, t3.
- the contact carrier Pc oscillates, around a trunnion Ax and an axis AA ′, between two conductors Cf1, Cf2 carrying the fixed contacts P3 and P4.
- These drivers are themselves in the form of a loop and joined to one or two terminals U, V, W. In the mode of shown embodiment the axes are perpendicular to the rear mounting plane Pf.
- the movable contact carrier Pc oscillates, around the axis AA ′, from a first position working, contacts closed, in a second working position, contacts also closed.
- This loop effect provides proportional contact pressure to the current that passes through the pole.
- the poles are never operated under load which reduces the nominal contact pressure, the size of the electromagnet is finding it diminished.
- the moving parts of the electromagnet actuate a movable slide Ra in translation parallel to the rear mounting plane Pf and acting on each spring of Rp pole via a Pi part.
- Fixed conductors Cf1, Cf2 realize with extensions or additional conductors leading to the charging (power) terminals U, V, W etc., one of the SC control diagrams of the motor or motors. These extensions or additional conductors are housed in the Bo box, on the side of the terminals charge.
- the mobile conductors Cm1, Cm2 of the contact carrier PC are distant, one by with respect to each other, so that a No magnetic core lodges between them. This core magnetic No cooperates with plywood Cp1, Cp2 fixed inside the switching chamber housing the pole.
- the moving contact parts Cm1, Cm2 are joined by a flexible electrical connection Tr and a conductor such as Co3 to a terminal source such as t3.
- the input and output terminals used for control are arranged forward.
- the input terminals A2, A1, A1 ', B1, B1' are intended to receive orders from motor control and the output terminals SA1, S21, S22 cooperate with the device main partner Ap.
- the main device Ap includes a locking contact Ve operated by the moving part of the electromagnet E and connected to two terminals 21 and 22 which can be connect to terminals SA1 and SA2 of module M.
- the coil Bb of the electromagnet El is supplied so as to be polarized in either direction.
- This command can be carried out by two change-over contacts auxiliaries 1a and 1b actuated by the mobile part of the bistable electromagnet El and associated to diodes 7a, 7b.
- Switching module M can have other contacts auxiliaries such as 3 and 6 also actuated by the movable part of the electromagnet El.
- the electromagnet El of the main apparatus Ap is powered by the MA on / off switch, the contacts Bp1, Bp2 and 6.
- the poles of power I1, I2 and I3 of the main device Ap are in the operating position "Sense one".
- Switching switches such as C1, C2 of the switching module M are in the position corresponding to this "sense one" operating mode (these poles are always in the closed position).
- the operator opens a contact Bp2 and close the associated contact Bp2.
- Contact opening cuts power of the coil B of the main unit Ap.
- the power switches I1 to I3 of the main device Ap opens.
- Closing the contact Bp2 causes the supply of the coil Bb of the module M which causes the switching of switching contacts such as C1, C2.
- the auxiliary contacts of module M switch and current is sent to electromagnet E of the main device Ap so as to operate the power switches 11-13.
- the electromagnet El of the switching module M can only switch when the power contacts I1 to I3 are open. This security function is provided by the Ve locking contact. On the other hand, the power contacts I1 to I3 close when the contacts of the switching module M are in the correct position.
- the auxiliary contacts In order not to cut the supply voltage during the stroke of the electromagnet El, the auxiliary contacts must change position after the electromagnet It has run its course or an important part of its course. A device for delay of change of state can be associated with these three contacts.
