По основному авт. св. № 455395 извес но устройство дл управлени искровым промежутком конденсаторной батареи, содержащее формирователь высоковольтных импульсов , вьшолненный, наттример в виде трансформатора с накопительными конденсаторами , коммутирующий элемент, причем дл повышени надежности устройства, его упрощени и удещевлени оно снабжено подключенным паралпельно, по крайней мере, части коммутируемой конденсаторной батареи вьшр мительным мостом, в диагональ которого параллельно коммутирующему элементу подключен стабилизирующий элемент.According to the main author. St. No. 455395 a device for controlling the spark gap of a capacitor battery, containing a high-voltage pulse shaper, an advanced natrimer in the form of a transformer with storage capacitors, a switching element, and to increase the reliability of the device, simplify it and increase it, it is equipped with a connected, at least part of switching capacitor battery is an interchangeable bridge, in the diagonal of which a stabilizing element is connected parallel to the switching element.

Однако известное устройство не обеспечивает компактности и простоты конструкции трансформатора, так как при требовани повышенной стабильности и 5т еньшени времени запаздывани искрового промежутка ферромагнитный материал дл импульсного трансформатора должен обеспечивать в импульсном режиме большое приращение индукции и высокую магнитную проницаемость , что требует, например, применени внешнего размагничивающего пол , получаемого от дополнительной размагничивающ обмотки и источника энергии.However, the known device does not provide compactness and simplicity of the transformer design, since with the requirement of increased stability and 5t of the lag time of the spark gap, the ferromagnetic material for the pulse transformer must provide in a pulsed mode a large increment of induction and high magnetic permeability, which requires, for example, using external demagnetizing the floor received from the additional demagnetizing winding and the energy source.

С целью повышени стабильности и надежности, уменьшени времени запаздывани , уменьшени габаритов и упрощени конструкции трансформатора, предложенное устройство снабжено резистором и двухпозидионным переключателем, соедин ющим накопительный конденсатор в одном из положений с первичной обмоткой трансформатора , а в другом положении через указанный резистор с вторичной обмоткой трансформатора .In order to increase stability and reliability, reduce lag time, reduce size and simplify the transformer design, the proposed device is equipped with a resistor and a two-position switch connecting the storage capacitor in one of the positions to the transformer primary winding and in a different position through the resistor secondary winding .

Claims

The drawing shows an electrical diagram of the attached device. Accumulating capacitor 1 using a two-position switch 2 through a resistor is connected to the secondary winding of the transformer 4. After charging the switched capacitor battery 5, a trigger signal is supplied to the switching element 6, and the capacitor 1 in the aperiodic mode (due to resistor 3) is discharged to the secondary winding transformer 4, With an appropriate choice of the winding circuit and the use of a ferromagnetic material with a large residual induction, the transformer core is magnetized way that the pulse is realized at the operating this mode of operation, when kotorm electromagnetic properties of the core are used almost completely. After remagnetising the core, the dip switch 2 is moved to the second position, the storage capacitor 1 is connected to the primary winding of the transformer 4, and the circuit is ready for operation. The two-position switch 2 can be controlled from the ground potential by an insulating rod. Switching is advisable to carry out in automatic mode after switching the sections of the capacitor battery. The transients that occur when switching sections of a battery require special interference against the spark gap control path. The application of the proposed device allows to significantly simplify the elements of interference protection, since if the control path is falsely triggered before the two-position switch 4 is moved to the second position, the spark gap does not start. The switching time of the switch 2 and the charging of the capacitor 1, which is a fraction of a second, is irrelevant in the synthetic test circuit, since usually the time interval between operating pulses is several minutes.
