Изобретение относитс к электротехнике и может быть использовано в светолокаторах и других установках с импульсными газоразр дными лампами.The invention relates to electrical engineering and can be used in optical light systems and other installations with pulsed gas discharge lamps.

Известно устройство, содержащее силовой трансформатор, выпр митель, подключенный через балластный резистор к накопительному конденсатору, к которому подключены основные электроды импульсной лампы, а поджигающий электрод через импульсный трансформатор св зан с генератором импульсов 1.A device comprising a power transformer, a rectifier connected through a ballast resistor to a storage capacitor to which the main electrodes of a pulse lamp are connected is known, and the igniting electrode is connected to a pulse generator 1 through a pulse transformer.

Недостатком этого устройства вл етс мала стабильность положени канала разр да в пространстве, что ограничивает возможности их применени в светолокаторах, так как при изменении положени канала световой луч выходит из пол зрени приемника . Дл уменьщени колебаний светового потока требуетс увеличивать размер пол зрени приемника, что ухудшает отношение сигнала к помехе от диффузно-рассе нного света.A disadvantage of this device is the low stability of the position of the discharge channel in space, which limits the possibilities of their application in light-transmitters, since when the channel position changes, the light beam leaves the field of view of the receiver. To reduce the fluctuations of the luminous flux, it is necessary to increase the size of the field of view of the receiver, which degrades the signal-to-interference ratio from diffuse-scattered light.

Наиболее близким к изобретению вл етс устройство, содержащее силовой трансформатор , подключенный первичной обмоткой через сопротивление к сети переменногоClosest to the invention is a device containing a power transformer connected by a primary winding through a resistance to a network

Недостатки этого устройства состо т в ограничении возможностей его использовани , так как напр жение поджига ламп должно быть меньще анодного напр жени .The disadvantages of this device are in limiting the possibilities of its use, since the ignition voltage of the lamps must be less than the anode voltage.

Claims

20 for connection to the AC mains, and the secondary winding is connected via a rectifier to the plates of a storage capacitor connected to the electrodes of a pulsed gas discharge lamp, equipped with a step-up transformer, a voltage multiplier rectifier and a variable resistor, the primary winding of the power transformer via ballast resistor connected to the terminals for connection to the AC network, and the secondary winding is connected to the plates of the storage capacitor, under the rectifier, Connected to the electrodes of a pulsed gas discharge lamp, equipped with a step-up transformer, a rectifier with a voltage multiplier and a variable resistor, the primary winding of the step-up transformer through a variable resistor connected to the input of the power transformer, the output of which is connected to the ignition electrode of the pulsed gas discharge lamp. The drawing shows a schematic diagram of the proposed device. The device contains a ballast resistance 1 through which a power transformer 2 is connected to an alternating voltage network, the secondary winding of which is connected via a rectifier 3 to a storage capacitor 4, to which the electrodes of a pulsed gas discharge lamp 5 are connected, and the igniter electrode of the lamp through a distributor 6 with a voltage multiplier, a step-up transformer 7 and a variable resistor 8 are connected to the primary winding of the power transformer 2. The device operates as follows. When the device is connected to the mains, the capacitor 4 is charged through the resistance I, the power transformer 2, and the rectifier 3 to the full voltage. At the same time, the capacitors of the voltage multiplier 6 are charged through a resistor 8 and a transformer 7 until the gap voltage of the cathode-igniting electrode of the lamp. The charge time of the capacitor 4 is less than the charge time of the capacitors of the voltage multiplying circuit 6, so that by the time the lamp flashes, the storage capacitor 4 is fully charged. The frequency of the flashes of the lamp is regulated by a variable resistor 8. At high power in the discharge circuit of the lamp, it is advisable to use a resistance of 1, for example, a choke. At the time of the lamp flash, the voltage on the primary winding of transformer 2 is close to zero, since all the voltage drops on resistance 1, which reduces the power dissipated on the transformer, because at maximum current, the voltage on the transformer windings is close to zero, and the linearity increases changes in the voltage on the igniter electrode, which increases the stability of the repetition frequency of the flashes. Due to the low power of the ignition circuit, the dimensions of the transformer 7 and the resistor 8 can be small. The economic effect of using the invention is achieved by reducing operating costs.
