Description

one

According to the main author. St. No. 355704 known igniter device, for example,. for dischargers, containing a hollow electrode with a hole, for an exhaust hole of a gas stream that ignites the electrothermal tube and an insulator that encloses the igniting electrode, which form the ignition chamber. In the device, in order to increase operating efficiency, increase speed and decrease power, the end surfaces of the ignition electrode and insulator made of gas-generating material, facing the sub chamber, are located in the same plane.

However, the known device does not provide high ionization efficiency of the arc gap in the presence of deionizing factors, such as gas blowing.

The proposed device makes it possible to increase the efficiency of arc arc mixing in the presence of deionizing factors, for example, a gas arc.

This is achieved by the fact that the hollow electrode of the igniting device is equipped with

one hole. At the same time, the axis of the holes are located in the same plane that coincides with the plane of the axes of the main electrodes of the arc gap, and are directed to the ends of these electrodes. Between the hole there are a series of holes, the axes of which are located in the same plane. The holes are cut through, and there is an insulation screen on the hollow electrode.

with apertures for the exit of the igniting-discharge plasma, corresponding to the apertures in the hollow electrode.

FIG. 1-4 shows the variations of the device.

The device consists of an ignition chamber, an ignition electrode 2, gas-generating, the sleeves 3 and a hollow outer electrode 4 with holes 5 for the directional exit of the heated gas (plasma

we).

The device works as follows. zom.

Plasma jets directed to the main electrodes of the charge between the

They cause the ionization of the gas in the intergrain Lrosgransgwe, which leads to the initiation of the arc.

 a large distance between the base electrodes, the number of holes 5 must be increased (fig, 2), while they can be connected by a gap (fig. 3), which makes it possible to more effectively ionize the electrode gap. I

When making the ignition device: with an insulating screen 7 (FIG. 4), the holes in the screen are like continuation of the holes of the hollow outer electrode.

When used autonomously to initiate an arc between two electrodes of the igniter, as per aut. St. No. 355704 is provided for the initiation of an arc in one case of five.

. When using the proposed incendiary device, arc archiving is provided in almost all cases.
