Abstract

The invention relates to electrical engineering. The goal is to improve mass-dimensional characteristics while maintaining reliability. This goal is achieved due to the fact that between the high-potential power supply 4. and the control electrodes of the electrovacuum device 2 are connected according to coils 3, 5 and 6 of inductance, having the same number of turns, wound with one forced pitch to one common cylindrical frame. In nominal mode, the inductance of coils 3.5 and 6 does not affect the mode due to the insignificant magnitude of the reactance of the coils relative to the impedance of the electrovacuum device 2. In the case of a breakdown of the latter, voltage surges occur on the inductors, eliminating them from the outputs of the high-potential power source 4 and thereby preventing its destruction and eliminating the need for special protection devices. 1 hp f-ly, 1 ill.

 about

The invention relates to electrical engineering and can be applied to power supply devices for vacuum devices and devices for their protection.

The purpose of the invention is to improve the mass-size characteristics while maintaining reliability.

The drawing shows a diagram of the device power supply of the vacuum device.

The device contains a high voltage source 1 connected to an electrovacuum device 2 through one inductance coil 3, a high-potential source 4 with power outputs connected to the beginnings of other inductance coils 5 and 6, the ends of which are connected to the corresponding electrodes of the control of the vacuum device 2.

The coils of 3.5 and 6 inductances are wound on one cylindrical frame, have the same number of turns, one common forced step of winding and are included according to. In the drawing, there is a parasitic capacitance 7 between the anode of the electrovacuum device and the source of high potential power source.

The operation of the power supply device for the electrovacuum apparatus is as follows.

The magnitude of the reactance of inductance coils 3, 5 and 6 is much less than the impedance of the electrovacuum device 2. As a result, switching on the inductance coils in nominal mode does not affect the operation mode. In addition, the nakzla current and the current network of the electrovacuum device are directed in opposite directions and the magnetic fluxes created by them mutually cancel each other out.

In the case of a breakdown of an electrovacuum device, the voltage of the parasitic capacitance 7 is applied to the inductance coils 3, 5 and 6, eliminating the sudden and uneven voltage variation at the outputs of the high-potential power source, and, therefore, the overvoltage between its outputs, which prevents the circuit elements from from build.

The length of the insulating cylindrical frame, on which the inductance coils 3, 5 and 6 are wound, and the forced winding pitch are designed to work without overlapping the insulating gaps.
