Definitions
- the present invention relates to a relay, in particular an electromagnetic relay.
- a known solution consists in assigning pulse width modulation (PWM) to the supply voltage and in this way reducing the coil current to an advantageous value for the desired period of time.
- PWM pulse width modulation
- the disclosure is based on the knowledge that the above object is achieved by a relay, which makes it possible to reduce the coil current by increasing the total resistance of the excitation coil or the excitation coils with unchanged supply voltage and thus to reduce the relay power or the electrical power and thus the heat dissipation power .
- the disclosure relates to an electromagnetic relay, having a yoke and an armature pivotably arranged on the yoke, which has an open position and a contact position with respect to the yoke, and which is designed from a magnetic field to be attracted from the open position into the contact position and to be held in the contact position, a first circuit branch which has a first capacitor and a first excitation coil connected in series therewith, a second circuit branch which has a second capacitor and a second excitation coil connected in series , wherein the first excitation coil and the second excitation coil are designed to provide the magnetic field for attracting and holding the armature, and a switching element which is arranged between the first circuit branch and the second circuit branch and has a first switching state and a second switching state, in which first switching state of the switching element, the first circuit branch and the second circuit branch are arranged in a parallel circuit, and wherein in the second switching state of the switching element the first excitation coil and the second excitation coil are arranged in a series circuit,
- the coil power of the first and second excitation coils is automatically increased from a pull-in power that must be provided to attract the armature from the open position to the contact position, to a lower holding power must be lowered in order to keep the armature in the contact position as soon as the armature is fully tightened in the contact position.
- the contact position of the armature is the position of the armature in which contact is established between the armature and the yoke and the relay is closed, that is to say the relay has fully pulled through.
- the design of the present relay with two excitation coils interconnected enables the total resistance R tot of the first and second excitation coils with individual resistances Ri and R 2 to be changed by converting the circuit arrangement of the two excitation coils from a parallel connection into a series connection of the excitation coils .
- Switching the parallel connection of the first and second circuit branches into the series connection of the first and second excitation coils thus increases the overall resistance of the first and second excitation coils. If the supply voltage remains unchanged, the increase in the total resistance of the series-connected first and second excitation coils in turn leads to a decrease in the coil current flowing through the first and second excitation coils. A reduced coil current in turn leads to a reduction in the magnetic flux through the first and second excitation coils and, associated therewith, to a reduction in the magnetic field of the first and second excitation coils.
- the first and second circuit branches Due to the low resistance of the first and second capacitors for the period in which the switching element is in the first switching state, the first and second circuit branches are arranged in parallel and the first and second capacitors are charged, the resistances of the first and second capacitors are used for the calculation the total resistance for this period is negligible.
- I represents the coil current and NI , 2 the number of windings of the first and second excitation coils.
- a reduction in the heat development of the excitation coils is achieved by reducing the coil current and thus reducing the coil power.
- a reduction in the development of heat is advantageous due to the low thermal capacity of the components.
- the first and second capacitors are designed to provide the first and second excitation coils with a charging current which is suitable for causing the magnetic field of the first and second excitation coils to attract and hold the armature.
- the first and second capacitors are charged by the applied operating voltage and consequently a charging current in the first and second circuit branches flows.
- the first and second capacitors are of low resistance and are dimensioned such that a high charging current flows, and thus a coil current is provided to the first and second excitation coils that is suitable for inducing magnetic flux and a magnetic field in the first and second excitation coils , by means of which the armature can be pulled into the contact position.
- the first and second capacitors are high-resistance in the second switching state.
- the first and second capacitors act as high-resistance resistors and ensure that the first and second excitation coils are supplied with a coil current which is suitable for inducing a magnetic field in the first and second excitation coils which is sufficient to hold the armature in the contact position.
- the first ohmic series resistor is an ohmic resistor of a coil which is connected upstream of the third diode and / or the plurality of third diodes connected in series.
- the switching element comprises a reed switch.
- the switching process of the switching element can be directly coupled to the armature tightening, in that both the switching process of the switching element and the armature tightening are effected by the magnetic field of the first and second excitation coils. This can also prevent a switching operation of the switching element from taking place without the armature having been fully tightened into the contact position beforehand
- the magnetic field of the first and second excitation coils flows through the reed switch.
- the switching point in time of the switching element can be matched as precisely as possible to the point in time at which the armature is fully pulled into the contact position.

- the RC element has a third ohmic resistor and a third capacitor.
- the third ohmic resistor and the third capacitor are in theirs Dimensioning matched to the first and second capacitors.
- the first and second capacitors are in turn dimensioned such that a complete charging of the first and second capacitors corresponds to a complete tightening of the armature into the contact position. A time at which the armature is fully drawn into the contact position can thus be determined over the duration of the charging of the first and second capacitors.
- the time constant of the RC element is preferably selected such that at the switching time of the switching element or the reed relay, the voltage across the switching element has decayed to almost zero and an almost identical voltage drops at the first and second excitation coils. As a result, high current peaks that can otherwise occur during the switching process of the switching element on the first and second capacitors can be avoided.

- the switching element is designed as a robust component with high switching accuracy and switching reliability.
- the transistor is a bipolar transistor.

If the dimensions of the RC element and the voltage divider with regard to the time constant are furthermore adjusted in relation to the dimensioning of the first and second capacitors with regard to the duration of the charging, the switching point in time of the transistor can be matched to the point in time at which the anchor is fully drawn into the contact position.
- the RC element is connected to the base connection of the transistor via the voltage divider, so that the time at which the transistor is switched to a conductive state and thus switches can be regulated via the time constant of the RC element and the voltage divider.
- the time constant of the RC element and of the voltage divider is preferably selected such that a positive influence on current peaks of the collector-emitter current of the transistor, which can occur when switching off, and the current steepness when switching on and off can be achieved. Furthermore, current peaks and voltage steepnesses of the collector-emitter current of the transistor can be reduced by the choice of the resistance ratio of the resistances of the RC element and the voltage divider.
