Description

one

The invention relates to electrical industry and can be used in the operation of lamps, in which the ignition voltage is higher than the supply voltage of the network.

Izveetio starting-regulating device for gas discharge laggp containing throttle, pulsed iovyshayushi, transient transformer, switching capacitance and thyristor, forming a relaxation generator of high-voltage emulsions, contributing to the ignition of lamp 1. However, such a device is cumbersome and difficult to excluatin.

The closest to the technical solution is a device for firing gas discharge lamps, containing a choke connected in series with a lamp, a relaxation high voltage pulse generator consisting of a ballast resistor, and a mioulsky transformer, a capacitor H of the thyristor of a pulse transformer 2. However this device does not have the option of increasing the amplitude; S Generated pulses before switching off when the lamina is ignited.

In order to increase reliability, expand diaozone of operating temperatures and reduce overall dimensions, the proposed device is connected by a switching capacitor, including

between primary windings and secondary windings of the transformer ballast sunrose.

As a ter: urine-inB11 body element with a positive temperature coefficient, resistelin can be used by an investigator, which allows the amplitude of the extracted pulses to be increased before disconnecting when the lamp is damaged.

In the drawing, a schematic diagram of the onriCbiBacMoro device is given.

The device contains a 11T circuit consisting of a series of connected ballast resistances 1, a primary winding 2 of a pulsed transformer, a switching condensate) and a 3 N secondary winding 4 of a 1M pulsed transformer. In parallel with the winding winding 2 li, the switching terminal 3 is switched on the tyrnstor 5, the winding electrode of which is connected to the anode through a thermal element 6 with a positive

temperature coefficient sshrotnvlsii. Resistance V is trimming and is selected taking into account the disarray of the tcristors on the basis of the switch. The pressure-sensitive element b is setted by the O. private part with CO. I, which simultaneously serves as the heater of the heater 6. The capacitor B shunts the power resistance 1 to reduce the loss of high-frequency pulses by using an rcjiepi-ipyeMbix device.

If it does not ignite, the heating of the ballast resistance will lead to a heat sensitive sensitivity, which can be applied to | Pravlk1ON-1, s101) (JAa iiipiirae, uCychAea, and a sphere, you can see an | its co-detector, which contributes to an increase in the amilitude of pulses produced by the device. At a further temperature, the heating of the thermal element (if the lamp does not light up), the control electrode triggers a current not sufficient to turn it on. The device can be switched on again only after cooling the ballast resistance, but at the temperature-sensitive switching element with a positive temperature coefficient of absorption.

The proposed device can be made in two versions. In the first variant, the device in the case of non-ignition of the lamp itself is periodically turned off and switched on with a certain time interval. In the second one, it doesn’t turn on again only after the power off of the IR network is disconnected from the thermoelectric element. In practice, this depends on the ballast resistivity parameters, switching switches and scopes: a needle needle with a positive temperature coefficient of resistance, and no change of the device clom is required.

The use of a nosistor as Tei) is a sensitive element with a positive temperature coefficient of resistance, its inclusion in the nanowire of the transducer electrode, which is bridged over the anode, located at the inside ;; ballast resistance allows newer efficiency and reliability of the device in the pellets, reducing its size and size. Starting device inside the throttle. In addition, the resistor, having a positive temperature coefficient of resistance in the region of both positive and negative temperatures, extends the range of working temperature of the device, ensures its

Zash, PTU by turning off in the event of a prolonged zazhnga1 n lamp, and also contributes to an increase in the amplitude of the generation of my pulses at the time, which is not expected to turn off.

Tests of the proposed device showed reliable ignition of gas-discharge lamps in the range of heat 40 - (- 60) ° C, disconnection of the device after 2-5 minutes after 11C1 repetitive work and increased from 1.3 to 1.5.
