Description

Изобретение относитс к высоковольтной импульсной технике, может бытЬ использовано при создании генераторов импульсных токов и напр женки,The invention relates to high-voltage impulse technology, can be used to create impulse current generators and voltages,

Известен емкостный накопитель с конденсаторами, разбитыми на параллельные группы одинаковой емкости, соедииенные последовательно с групповыми защитными резисторами IJ. Последние выполнены сешшонироваиными и име- ют отпайки дл регулировани сопротивлени в зависимости от режима работы накопител .Known capacitive drive with capacitors, divided into parallel groups of the same capacity, connected in series with the group protective resistors IJ. The latter are made seshoniroviynymi and have taps to adjust the resistance depending on the mode of operation of the drive.

Недостатки данного.накопител - большие вес и габариты групповых защитных резисторов, так как каждый из них должен рассчитыватьс на поглощение во вре м аварии основной части энергии накопител .The disadvantages of this accumulator are the large weight and dimensions of the group protective resistors, since each of them must be designed to absorb the main part of the storage energy during an accident.

The capacitive drive works as follows: Periodically opening: a relatively slow charge of the capacitors from the charging device 3i goes and then their fast through the switching discharger 4 to the load 5. When one of the capacitors of the group 1 is broken, the same capacitors discharge to it . Spark gaps 6j, 6l, of the emergency capacitor unit are punched as a result of the potential difference between them between the terminals of the capacitors of the damaged Ij and intact 2 and 2 g groups.
