Definitions

  • the present invention relates to a ballast with the features of the preamble of claim 1 and a method and an apparatus for disinfecting waters.
  • a generic ballast is known from DE 196 37 906 A1.
  • the connected radiator is operated in operation at a frequency of about 20 kHz to 50 kHz, while the conventional ballasts operate at the mains frequency of 50 Hz.
  • two connection lines are routed to each heating coil of the connected gas discharge lamp.
  • the heating coil is via these lines subjected to a heating voltage, which causes a heating of the coil.
  • a heating voltage which causes a heating of the coil.
  • the heating voltage is switched off and a connecting line of each heating coil is supplied with the operating voltage of the gas discharge lamp.
  • the switching between the heating voltage and operating voltage takes place in the generic ballast with semiconductors. In operation, only one line per coil is energized, so that the other line is open.
  • the power of the connected UV emitter is controlled by a pulse width modulation.
  • the distances between a control unit containing the ballasts and the UV radiator arrangement operated therewith can be about eight in a sewage or drinking water disinfection system Meter, which is considered structurally particularly in large systems as disadvantageous.
  • ballast with the features of claim 1 and by a device having the features of claim 5 and a method for operating a sewage or drinking water disinfection system having the features of claim 8.
  • connection lines can be at almost any potential. Relays are also uncritical regarding their transient response.
  • closed at rest relay normally closed - NC
  • the at least one relay causes the parallel connection in the idle state, the relay and the control can be free of load during operation.
  • the component cost is minimized if a quadruple changeover relay is provided for every two radiators.
  • the UV radiation is generated by at least one radiator of the type of a gas discharge lamp having two with respect to a gas discharge gap heating coils, wherein for each such radiator four in total are provided by a ballast to the radiator leading electrical connections, namely two is provided for each heating coil of the radiator, that before the ignition of the radiator, the two leading to each heating coil connecting lines are acted upon by a heating voltage and after the ignition and during operation each two connecting leads leading to each heating coil are electrically connected in parallel, the distance between the respective ballast and the UV lamps can be almost arbitrarily large.
  • the connecting lines between the ballast and the radiator may have a length of at least eight meters, in particular more than 15 meters.
  • the load of the ballast in the device is reduced when a capacitor is connected in parallel to each heating coil.
  • the relays used can be relatively small dimensions, if they are always switched load-free, in particular the heating voltage, the ignition voltage and the operating voltage is not applied during a switching operation of the relay to the connection lines.
  • the electric power supplied to the heating coils is gradually raised for heating and so the normally high inrush current is limited for cold heating coils.
  • the lifting of the power is preferably carried out by means of pulse width modulation or power limitation.
  • the electric power supplied to the radiators for operation can be initially reduced compared with the normal operation and then raised, so that the operating parameters of the system are achieved gradually and without load peaks of the individual components.
  • FIG. 1 shows a simplified circuit diagram for illustrating the present invention.
  • a UV radiator 1 is connected to a ballast 3 via a four-wire connecting line 2.
  • the ballast 3 includes a heating voltage source 4, an operating and ignition voltage source 5, a in its rest position (NC) illustrated dual-switching relay 6 and two capacitors. 7
  • a controller 10 controls the parameters of the voltages and currents delivered by the power supplies 4 and 5, as well as the relay 6.
  • the output Voltages and currents are delivered via lines 11 of the heating voltage source 4 and lines 12 of the operating and Zündschreibs provoke 5 to the relay 6 and passed from there depending on the switching state of the relay 6 to two coil 13.
  • the relay 6 is first supplied with electricity, so that it attracts and connects via the lines 11, the coil 13 with the Schuwoods provoke 4.
  • the output current of the heating voltage source 4 is slowly raised to the nominal value and the coil 13 is heated.
  • the operating and ignition voltage source 5 is also caused by the controller 10 to give an ignition pulse via the lines 12 to the coil 13, so that the gas discharge is ignited.
  • the controller 10 is also caused by the controller 10 to give an ignition pulse via the lines 12 to the coil 13, so that the gas discharge is ignited.
  • the lines 12 to the operating voltage which is initially held in the manner of a dimmer at low power.
  • the relay 6 drops and switches in each case the lines leading to a coil 13 in parallel.
  • the capacitors 7 smooth out possibly occurring voltage peaks.
  • the high-frequency operating voltage is then fed to both sides of the coil 13.
  • the branch of the lines initially connected to the heating voltage supply 4 is then not open.
  • the power of the radiator 1 is raised to the nominal value. The commissioning of the radiator 1 is completed.
  • the relay 6 can be performed as a four-way relay, so that the circuit remains simple.
  • the parallel connection of the respective lines leading to a coil 13 can be carried out with any desired switching means.
  • the novel ballast preferably has relays for parallel connection of the connection lines during operation, which has several advantages over the current circuit.
  • the novel circuit logic now couples the coils to the heating circuit by means of relays, and during operation the two emitter leads on each coil side are short-circuited at the ballast. This results in operation on two parallel connection lines and the power is distributed symmetrically to them. As a result, there is no open line and the repercussions of the high-frequency operating voltage on the individual circuit parts are minimized. In practice, cable lengths of over 50m are possible.
  • the heating method is characterized in that the heating current can increase only slowly by slowly increasing the pulse width by means of digital control of the primary side of the main transformer.
  • the internal resistance is lowest. Since the source resistance of the heating circuit is very low, a very high initial current would flow without this control.
  • the logic is very good, since the digital control logic, the independent switching on the Relay enabled. That is, just before the power amplifier turns on the heating current, the relay is switched. The operating time of the relay is taken into account. Thus, current flow is avoided at the contacts at the switching moment, which contributes significantly to the relay life.
  • the emitters have ignited, the power is limited to such an extent that, despite the very low-impedance state of the emitter, the emitter current is kept below rated current.
  • this radiator current is divided on both coil sides and only slightly loaded the relays. A capacitor over the heating coils ensures a gentle transition.
  • the digital control of the entire ballast unit combines ignition, preheating and normal operation. All parameters, such as preheating time, preheating current and ignition are adjusted in the control software to the spotlight.
  • the heating logic is optimized for the special application with UV amalgam lamps of high power, in which the operating voltage for the UV lamps has a frequency of 10 kHz to 100 kHz, in particular between 20 kHz and 50 kHz.
  • These low pressure mercury lamps have very low impedance filaments and are therefore not comparable to filaments known from lighting technology.
  • the heating current is about 3 A.
  • connection cable instead of a four-wire connection cable and connecting cables with more than four wires, especially with eight wires can be used.
  • four lines are then connected in parallel in operation for each helix.
  • the characteristic impedance of the connecting cables is thereby better adapted to the requirements of long connecting cables.
