Definitions
- the invention relates to a circuit arrangement for operation of a single voltage relay at which for a a relay inrush current from a timer unit predetermined time provided and during a subsequent Holding time reduced compared to the relay inrush current Relay holding current is provided.
- Such a circuit arrangement is in the US patent 5,107,391.
- a relay i.e., current flowing through its excitation coil
- an electronic switch in the form of a field effect transistor controlled.
- the size of the holding current is due to the duty cycle determined by electrical impulses that affect the electronic Activate switch.
- Using a temperature sensor is the temperature of the relay and by means of a voltage sensor the voltage present at the excitation coil of the relay measured.
- the relay is switched on due to the voltage change occurring at the excitation coil of the relay recognized and causes a timer unit to start.
- This timer unit controls by means of a continuous pulse through the electronic switch so that one for the safe switching on of the relay sufficient inrush current flows.
- the continuous pulse ends and it flows only the one determined by the pulse duty factor Holding current through the relay.
- the circuit is capable of fluctuations the operating voltage by measuring the voltage on the excitation coil of the relay to take into account, however, is the circuit for operation on a voltage source with a given Nominal voltage provided, e.g. B. on a car battery with a voltage of 12 V.
- a voltage source with a given Nominal voltage provided, e.g. B. on a car battery with a voltage of 12 V.
- the invention has for its object a circuit arrangement to indicate the operation of a relay in the event of deviations of the relay from its nominal values does not affect the Impact the level of the inrush or holding current and at Circuit dimensioning need not be taken into account.
- the circuit should use one and the same relay can be used with different operating voltages his.
- This task is at the beginning of a circuit arrangement specified type according to the invention solved in that the only Voltage is a switching voltage and the relay inrush current and the relay holding current are constant currents, the at least one constant current source fed by the switching voltage supplies. So it is used both as a relay inrush current and a constant current as a relay holding current used, the size of which does not depend on deviations of the relay from its nominal values from the operation of the circuit arrangement operating voltages of different sizes is influenced.
- the Constant current source the relay inrush current. After switching on of the relay and expiration of the predetermined by the timer unit Time becomes the constant current on the relay holding current reduced.
- the circuit arrangement can also be constructed so that during the time predetermined by the timer unit and during the subsequent holding period a first constant current source provides the relay holding current and that during the from the timer unit predetermined time a second constant current source provides a constant current that the Relay holding current with formation of the relay inrush current superimposed.
- Constant current can advantageously be a switch lie during the predetermined by the timer unit Time is closed. After that time will the switch is opened, this will easily Switchover between the relay inrush current and the relay holding current realized.
- the timer unit and / or the switch can be an auxiliary voltage need. Can advantageously for this auxiliary voltage a voltage drop across at least one in line with one of the constant current sources switched electrical component be used.
- a resistor can be used as an electrical component, for example be used. Because of the resistance flowing constant current is also the voltage across this Resistance drops, constant and can be used as an auxiliary voltage be used.
- Zener diode As an electrical component can also advantageously a Zener diode can be used.
- a Zener diode has the advantage that the voltage drop occurring at it is constant even then is when the current flowing through the zener diode changes. This can e.g. if a relay is used, the a changed inrush and / or holding current and thus adjusted constant currents required.
- the advantage just mentioned also occurs when in as electrical components Series connected diodes can be used.
- Constant current sources for example a constant current of the same Deliver size.
- the relay is inrush current twice the relay holding current.
- the circuit arrangement 1 shown in FIG. 1 for operation a relay is in series with an excitation coil SP of a relay connected; a voltage U created.
- the voltage U is a switching voltage, i. H. at Applying the voltage U should switch the relay. simultaneously the voltage U serves as the operating voltage for the circuit arrangement and the relay. As long as no switching voltage U is applied is, the circuit arrangement is in one de-energized idle state, a switch SCH is closed.
- a constant current source KS1 drives one Constant current IK1 through a Zener diode ZD and through the excitation coil SP of the relay. Because of the closed switch SCH also drives a constant current source KS2 a constant current IK2 through the switch. This current adds up a node 2 with the constant current IK1; it flows in Current of size (IK1 + IK2) as a coil current ISP through the Excitation coil SP of the relay.
- the constant current source is KS1 dimensioned so that it delivers a constant holding current.
- the constant current source KS2 supplies the difference the inrush current required for the relay; in this Case, this difference is the same as the holding current of the Relay.
- the excitation coil SP of the relay is now from the inrush current flows through, the relay picks up, d. H. it on. Due to the constant current flowing through the Zener diode ZD IK1 has an auxiliary voltage on the Z-diode ZD from which via conductors 3 and 4 of a timer unit ZE as a supply voltage UH is supplied.
- the timer unit ZE begins to work and opens after an adjustable time that is greater than that Switch-on time of the relay used must be via a connection 5 the switch SCH.
- the open switch SCH can be the constant current IK2 of the constant current source KS2 no longer flow; through the excitation coil SP of the relay only the constant current IK1 of the constant current source flows KS1 as holding current. This means that after the switch-on process is completed the excitation coil SP only with the holding current is applied, in this case half of the Relay inrush current.
- the relay with the excitation coil SP is therefore during the switch-on process from the constant current IK1 of the constant current source KS1 and the constant current IK2 of the constant current source KS2 traversed.
- the Relay only from constant current IK1 of the constant current source Flown through KS1.
- the size of the currents IK1 and IK2 is from the constant current sources KS1 and KS2 determined; possible deviations z. B. the coil parameters have their nominal values no influence on the size of the currents.
- the state is at the top of a diagram the switching voltage U, including the state of the output the ZE timer unit, including the state of the switch SCH and below the course of the coil current ISP over the Plotted time.
- the switching voltage U including the state of the output the ZE timer unit, including the state of the switch SCH and below the course of the coil current ISP over the Plotted time.
- On a horizontal timeline three times t1, t2 and t3 are marked.
- At the time t1 becomes the switching voltage U to the circuit arrangement applied;
- at time t2 is that of the timer unit ZE elapsed time ( ⁇ t1) and at time t3 is the circuit arrangement of the switching voltage U again Cut.
- the timer unit works and the predetermined by the timer unit Time is running; the switch is on and through the relay flows a coil current ISP, which results from the constant currents IK1 and IK2 additively put together. This coil current is the inrush current ES.
- the timer unit has turned off the switch SCH at time t2 and only flows through the relay as coil current ISP still the current IK1, which forms the holding current HS.
- the circuit is able to operate over a wide temperature range reliably control a relay because of the constant current sources KS1 and KS2 the constant currents IK1 and IK2 independently provide from the amount of temperature. Affect as well temperature-dependent changes in resistance the excitation coil SP does not measure the level of the currents. Because of the during the holding period of the relay compared to the constant Inrush current (e.g. half) reduced constant Holding circuit only requires a part of the circuit arrangement (e.g. about half) of the energy needed to operate with only a current equal to the inrush current would be required. There is less power loss, the relay becomes thermally less stressed and the service life of the relay coil elevated.
