Definitions

  • the present invention relates to a switching device for switching on and off larger consumer powers to an alternating current network and / or for a definable period of time to an alternating current network with a plurality of spatially separate consumers which can be switched on by glow lamp buttons, according to the preamble of claim 1.
  • time switches especially as staircase lighting machines, equipped with pneumatic or mechanical inhibitors as time-determining elements
  • timers have also been equipped with an electronic time circuit, especially of the type of a semiconductor compact component (IC), which has a master oscillator of adjustable higher frequency and a resettable frequency divider controlled by this and on which a signal with an easily selectable and changeable time delay for the control of the relay can be removed.
  • IC semiconductor compact component
  • the present invention is therefore based on the object of designing or improving the switching conditions of the switching device as cheaply as possible for the problem described, so that the circuit with possibly unavoidable bruises of a residual size already by the design of the remanence relay and independently of or in Connection with preferred time and / or phase conditions takes place, on the one hand, as close as possible to the zero crossing of the AC voltage and, on the other hand, also in the case of time switches, contact bruises can be avoided with great certainty by means of defined determination of the switching times, or at least cannot have a significant effect.
  • the above-described object is achieved in a switching device of the type according to the preamble of claim 1 by the features of the characterizing part of the same.
  • This solution conveys the technical progress that the switchgear can be structurally improved in terms of size, ie. takes up less space with the same switching capacity, and greater functional reliability is guaranteed due to the protection of the contact pieces and the better timing of the switching times.
  • the switching device is adapted to the conditions of the various existing installations in a clear and easily understandable manner that it can be used to easily replace an older type of any customary training without laborious checking of details if the older copy is no longer functional.
  • the circuit arrangement of the switching device - also in its special training as a time switch - according to the teaching of the invention is considerably less complex than the known ones in the relevant technology, and is therefore also cheaper from the outset.
  • the excitation coil and the magnetic circuit of the remanence relay are dimensioned in such a way that the current is sufficient to cause the magnetic reversal once the peak value has reached 75.7 times.
  • the actuation of the contact set is in the phase range between "f" and "g" of the AC voltage "a", ie. Any bruises also occur in an area with low voltages and currents, where they cannot have any disruptive effects.
  • phase values 45 ° and 135 ° or 225 ° and 315 ° there are areas in which the application of the excitation coil is to be blocked.
  • the values of the first time derivative "du / dt" can be used, which can be between 0.5 times the peak values (smaller than this) and both positive and negative.
  • the positive areas "h” are to be used for the switch-on process and the negative areas "i" for the switch-off process.
  • the teaching described above with reference to FIG. 1 is used in the exemplary embodiment in FIG. 2 for a delay module for generating control signals for the two current paths of the excitation winding connected in parallel.
  • the AC network is connected to terminals (7) and (22) (see Fig. 3).
  • the rectifier construction Unit lol with the charging capacitor lo2 the AC voltage is rectified so that the peak voltage occurs as a positive DC voltage at its output lo3; the rectifier assembly 1o4 with the charging capacitor 1 0 5 is used in a corresponding manner to generate the negative DC voltage value equal to the peak voltage, which can be removed at its output lo6.
  • the module lo7 is used to generate the first time derivative of the AC voltage and its full-wave rectification - without any smoothing - so that the two half-waves of the first time derivative occur as positive sine half-waves at their output.
  • the voltage dividers 1 0 9, llo in the output bring about the adaptation of the voltage values to the required quantities.
  • the amplitude values "u" of the alternating voltage 113 are conjunctively combined with the positive o, 75 times the value of the peak value (114) or with the negative (115), so that at the output 116 or 117 an H signal ("1") only occurs when "u" is at least equal to 0. 8.U (an inversion element may be connected or inserted in the case of the negative values at the AND gate 112).
  • the AND gate 118 combines the full-wave rectifier signal at the input 119 of the first time derivative "du / dt" with its 0.5 times peak value at the node 12o and at the other input.
  • the signals at the outputs 116, 117 in the AND gates 121, 122 are conjunctively linked to the signal at the output 123 of the AND gate 118.
  • the output signals on the lines 124, 125 act on the first input 128 of the NAND gate 129 and the one input 13o of the driver AND gate 131 via negation elements 126, 127.
  • the second inputs 132 and 133 are connected to the output lo3 of the rectifier Unit 1 0 1 connected as a power source.
  • the circuit (not shown) of the button is connected to the third input 134 of the NAND gate 129.
  • the remanence relay 1 (cf. also FIG. 3) is connected to the terminals (for example 8, 26 in FIG. 4) via the two parallel current paths (64 with thyristor 63) and 69; the control takes place in the above-described embodiment for switching on via line 135 from output 136 of NAND element 129, for switching off via line 137 from output 138 to control electrode 62 of thyristor 63.
  • the control electrode 62 of the thyristor 63 is acted upon by the output signal 58 and thus triggers the switching off of the remanence relay; it is switched on via terminal 18 using the push-button circuit (not shown) connected there. Further details on this, which also apply to the above-described exemplary embodiment of FIG. 2, are explained below with reference to the description of the exemplary embodiment in FIGS. 3 and 4.
  • the excitation winding of the remanence relay 1 is connected directly via the line 2 to the outer terminal 3, which ait during installation in all cases, namely the four-wire system (Fig.4a) via line 4, the three-wire system Connectivity (Fig. 4b) via line 5 (only once) and the three-wire system without connectivity (Fig.4c) via line 6 is connected to one pole 7, 8 or 9 of the AC network.
  • the excitation winding of the remanence relay 1 is connected to the circuit node lo, at which the line is divided into the two branches in which the current flows in the opposite sense, as indicated by the arrows and as will be explained below.
  • actuation of the glow lamp button 13c connects to the latter via the conductor bridge 27, the outer one Terminal 28, the dashed line 29, the switch arm 3o from the normally closed contact to the counter contact 32, the line 33, the outer terminal 34 and the glow lamp Pen button 13c is connected on the opposite side directly to the other pole 39 of the AC voltage, which is connected to the outer terminal 37 and the line 38.
  • the remanence relay 1 is thus brought into the working position by a current pulse in the direction of arrow 11, ie. the normally closed contact 17 is interrupted and the switch arm 3o is brought into the working position with a connection between the working contact 4o and the mating contact 32.
  • the lamp 42 connected on one side to the one pole 7 of the AC network is connected on the opposite side via the line sections 43, 44 and 21 to the other pole 22 via the conductor section 41 and the outer terminal 37.
  • this consumer connection takes place from one pole 8 via the line bridge 45, the outer terminal 34, the line sections 33, 41 with the switch arm 3o in between between the make contact 4o and Mating contact 32, the outer terminal 37, the line section 46 to the lamp 47 connected to the other pole 26 via the line 25.
  • the lamp 49 connected to the one pole 9 via the line section 48 is correspondingly connected via the line sections 5 0 , 35 and 51, the outer terminal 34, the line pieces 33, 41 with the intervening switch arm 3o with mating contact 32 and make contact 41 and finally the line piece 38 connected to the other pole 39 of the AC network.
  • the semiconductor compact brick (IC) 52 serves as a time circuit with a time-determining element for the dropout delay or pulse lengthening of the operating state “on” in the same way, the semiconductor compact brick (IC) 52, which is connected via node 53 with a positive voltage to node 54 the AC network via the rectifier arrangement, consisting of the diode 55 and the resistor 56 with an intermediate capacitor 57 with a parallel resistor 57a, is supplied with correctly polarized direct current and at its relevant connections the adjustable RC element 58 for tuning the built-in master oscillator lies.
  • the time circuit is permanently in operation when the AC voltage is applied per se and in the case of FIGS. 4b and 4d after connection to the AC voltage via the actuated work contact to the outer terminal 56 during the operating state "on”.
  • a pulse occurs at the Q output 58 via the Zener diode 59 and the voltage divider 6 0 , 61 and a pulse at the control electrode 62 which ignites the thyristor, so that a pulsating direct current of the polarity indicated by the arrow 12 flows from the circuit node lo via the line section 64, the diode 55 and via the line already described to the other pole 22 or 26 or 39 of the AC network through the excitation winding of the remanence relay 1, which because of its reverse polarity, this causes it to drop, the normally closed contact 17 and the switch arm 3o returning to their starting position, ie the consumer circuit is also interrupted.
  • the capacitors 65 and 66 are not functionally necessary, but they can be useful for suppressing external sources of interference.
  • the line section 67 can optionally be replaced by the dashed 68.
  • a diode 69 is inserted in branch 11.
