Definitions
- the present invention relates to a glow starter with an electronic control circuit.
- SiC igniters made of SiC without pressure sintering have been known for some time.
- the problem here is that the heating-up times, until the glow igniters have reached their operating temperature, are generally relatively long. This significantly limits the range of conventional SiC glow igniter arrangements and thus the usability for certain applications.
- the thermal capacity of the SiC glow starter can in principle be reduced, for example by means of other geometric configurations. If this happens, e.g. by thinning the arrangement, this can lead to mechanical instability, which is undesirable.
- the cold resistance of the SiC igniter can be reduced by suitable choice of material and / or material treatment. However, if the cold resistance of the igniter is reduced, this can also lead to a changed resistance in the heated state. The reduction in the cold resistance of the detonators is therefore typically accompanied by rapid overheating of the detonators and the associated thermal destruction.
- SiC glow igniters it is desirable to apply SiC glow igniters to a wider application, particularly those applications in which faster heating times can be achieved. In particular it is It is desirable to achieve heating-up times which make gas burner / water heating applications usable and / or reduce the starting emissions in heating systems by faster ignition of the fuel mixture.
- the object of the present invention is to provide something new for industrial applicability.
- a first basic idea of the invention accordingly proposes to use a combination of an SiC glow starter with reduced cold resistance and a voltage supply which provides suitable heating behavior.
- the line supply can be designed to keep the inrush current at least substantially within a predetermined switch-on value field. It is particularly preferred if the glow igniter arrangement is realized with a pressure-free sintered SiC glow igniter. With this production method, the cold resistances can be set particularly well and cold resistances with a value below or around 300 ohms can be provided. This resistance value already results in such a rapid heating behavior that the application in desired areas can generally be implemented without problems.
- the line supply is preferably designed to control and / or regulate the inrush current to an end value or into an end value range. In a particularly preferred variant, this is done via a thyristor arrangement connected in series with the glow igniter. Input and / or output diodes can be connected upstream of the thyristor arrangement, which ensure polarity reversal security.
- the series connection has the advantage that an improved failure safety is given because even if the voltage supply fails briefly, the current is still limited by the glow igniter, so increased operational reliability is guaranteed.
- the igniter arrangement according to the invention can also be used as a heating element and can in any case be operated in a self-stable manner on mains voltage.
- the invention is described below only by way of example with reference to the drawing. In this shows:
- a glow igniter arrangement 1 generally designated 1, comprises a glow igniter 2 and a power supply 3, which is connected in series with the glow igniter 2 between the phases of an AC power network 4.
- the glow starter 2 which is made in a manner known per se from silicon carbide, has a geometry suitable for a specific application and a cold resistance of around 300 ohms.
- the SiC glow starter can be used in the usual way
- the power supply 3 is designed as a two-pole power supply with two input / output poles 3a, 3a '. Behind the input / output poles 3a, 3a ', the access lines branch into an upper 3b and a lower 3b 1 circuit branch. In order to ensure a current and polarity-independent flow of current between these branches, diodes 3cl to 3cIV are connected between the input / output poles 3a, 3a 'and the upper and lower circuit branches 3b, 3b'. First, a thyristor 3d extends between the upper and lower circuit branches 3b, 3b ', to which a current-limiting series resistor 3e is connected. The total current can be determined by the arrangement at the series resistor 3e which limits the stro.
- the thyristor 3d is driven via the control circuit 3f, which is only shown by way of example and is provided only by way of example with usable component names. This is designed so that the desired current is obtained through the glow starter in the event of voltage fluctuations in the AC power network between 90 and 250 V.
- the silicon carbide glow igniter properly connected to the circuit in FIG. 1 can be used in gas and water heaters without any problems, regardless of production fluctuations and offers the advantage of only low starting emissions.
