(54) УПРАВЛЯЕМЫЙ РАЗРЯДНИК(54) CONTROLLED DISTRIBUTOR

Изобретение относитс к импульсной электроэнергетике и предназначено дл использовшш в малоиндуктивных разр дных цеп х генераторов импульсных токов дл коммутащш знерпш, запасенной накопителем.The invention relates to a pulsed electric power industry and is intended for use in low-inductance discharge circuits of impulse current generators for switching power stored by a drive.

Из основного авт.св. №527786, известен управл емый разр дник, содержащий шины, два основньк электрода, один управл ю.идай, расположенный между основными, диэлектрик, и канал инициирующего импульса, например, кабель, подключенный одним полюсом к управл ющему электроду, в котором дл уменьшени индуктивности, расширени диапазона управл емости и увеличени пропускной способности по току, электроды разр дника размещены на одной стороне диэлектрика, толщина которого меньше минимального рассто ни между основными электродами, а друга сторона диэлектрика снабжена токопроводом, электрически соединенным с одним из основных электродов И другим полюсом канала инициирующего импульса }.From the main auth. No. 527786, a controlled arrester is known that contains busbars, two main electrodes, one control unit located between the main dielectric, and an initiating impulse channel, for example, a cable connected by one pole to a control electrode in which to reduce inductance , extending the controllability range and increasing the current carrying capacity, the discharge electrodes are placed on one side of a dielectric, the thickness of which is less than the minimum distance between the main electrodes, and the other side of the dielectric clears bzhena current lead electrically connected to one of the main electrode and the other channel pole} initiating pulse.

К недостаткам такого разр дника относитс то, что количество образующихс стримеров и каналов разр да от импульса к импульсу непосто нно , а следовательно, непосто нна и индуктивность всей разр дной цепи. Кроме того, невозможно заранее определить собствеьшую индуктивность создаваемого разр дника, так как она зависит от количества каналов, развившихс на единицу длины поджигающего электрода и равномерности распределени разр дой по поверхности диэлектрика.The disadvantages of such a discharge are the fact that the number of streamers and discharge channels formed from a pulse to a pulse is not constant, and therefore the inductance of the entire discharge circuit is also not constant. In addition, it is impossible to determine in advance the own inductance of the created arrester, since it depends on the number of channels that have developed per unit length of the ignition electrode and the uniformity of the discharge distribution on the surface of the dielectric.

Цель изобретени - стабилизаци разр дных характеристик (времени срабатывани и индуктивности разр дника) путем стабилизации количества каналов разр да.The purpose of the invention is to stabilize the discharge characteristics (response time and inductance of the discharge) by stabilizing the number of discharge channels.

Это достигаетс тем, что в известном разр да : ке токопровод выполнен с продольными прорез ми , расположенными напротив зазора между основными электродами. Кроме того, указанные прорези могут быть заполнены твердым диэлектриком.This is achieved by the fact that at a known discharge: the conductor is made with longitudinal slits opposite the gap between the main electrodes. In addition, these slots can be filled with a solid dielectric.

На фиг.1 дана принципиальна схема разр дникaj на фиг.2 - вид по стрелке А на фиг. 1.In Fig. 1, a schematic diagram of the discharge aj in Fig. 2 is given - view along arrow A in Fig. one.

Claims

The main electrodes 1 and the control electrode 2 are insulated from the current conducting 3 by the dielectric 4. The energy storage device 5 is connected to one of the main electrodes 1 and the current line 3, and the load 6 is connected to the second main electrode 1 and the current line 3. The discharge voltage is controlled by of the initiating pulse channel 7 .. In the conductor 3, in the zone between the main cells 1, longitudinal proresidiirins are made, which are selected depending on the required number of discharge channels, based on the total width of the conductor. The width of the web when it is selected is in the range of 8-12 mm. The conductor 3 is made of metal with low resistivity (copper, aluminum). To make the conductor surface and remove air from the slots, the latter are filled with a solid dielectric (epoxy, paraffin, polyethylene, etc.). The use of the proposed design of the discharge makes it possible to reduce by a factor of 2-3 the specific surface capacitance and, with the same parameters of the ignition pulse, provide the specified (by the number of longitudinal bridges) number of discharge channels and inductance of the discharge. Such a construction facilitates the formation of more powerful streamers, which then grow into discharge channels, which stabilizes the operation of the discharge and the entire discharge circuit as a whole, and moreover allows one to calculate the inductance of the discharge at a design stage with higher accuracy. Claims of the invention 1. Controlled detector according to the author. St. No. 527786, characterized in that, in order to stabilize the discharge characteristics, the conductor is made with longitudinal projections located opposite the gap between the main electrodes.

2. Discharge according to claim 1, characterized in that said longitudinal slots are filled with a solid dielectric. Sources of information taken into account in the examination I. USSR Author's Certificate No. 527786, cl. N 01 15/00,1973.
