Description

(54) УСТРОЙСТВО ДЛЯ ЗАЩИТЫ ЭЛЕКТРОВАКУУМНОГО ПРИБОРА ОТ ПОВРЕЖДЕНИЙ ПРИ ВНУТРЕННИХ ПРОБОЯХ(54) DEVICE FOR PROTECTION OF ELECTRIC AND VACUUM DEVICES AGAINST DAMAGES DURING INTERNAL ACCIDENTS

ратном току от управл емого источника питани ./ground current from a controlled power source ./

На чертеже приведена блок-схема предлагаемого устройства,The drawing shows a block diagram of the proposed device,

Устройство содержит управл емый источник 1 питани , электровакуумгалй прибор 2, подключенный к управл емому источнику I через резистор 3. Параллельно электровакуумному прибору 2 через диод 4 подключен выход формирунйцей линии 5, ко входу которой через токоограничительный элемент 6 подключен зар дный источник 7. Волновое сопротивление формируилцей линии 5 выбираетс  большим сопротивлени  дуги, возниканщей в электровакуумном приборе 2, а врем  восстановлени  обратного сопротивлени  диода, 4 больше, чем врем  гашени  дуги .The device contains a controlled power source 1, an electrovacum device 2 connected to a controlled source I via a resistor 3. Parallel to the electrovacuum device 2, a diode 4 is connected to the output via a form 5 line, to the input of which a charging source 7 is connected. Forming line 5 is chosen for greater resistance of the arc arising in the electrovacuum device 2, and the recovery time for the reverse resistance of the diode 4 is longer than the arc extinction time.

В ключевом режиме работы электровакуумного прибора лини  5 зар жена от источника 7 (в качестве которого может быть использован делитель напр жени ) через элемент 6 до напр жени , меньшего, чем минимально возможное напр жение на электровакзгумном приборе в ключевом режиме. Диод 4 закрыт и лини  5 не вли ет на работу прибора 2.In the key mode of operation of an electrovacuum device, line 5 is charged from source 7 (for which a voltage divider can be used) through element 6 to a voltage lower than the minimum possible voltage on the electroacoustic device in the key mode. Diode 4 is closed and line 5 does not affect the operation of instrument 2.

При пробое и возникновении электрической дуги в приборе 2 диод 4 отпираетс  и возникает переходной процесс обусловленный наличием линии 5, который приводит к прекращению электрической дуги. Во врем  переходного процесса прибор 2 восстанавливает электрическую прочность. После восстановлени  электричес)кой прочности прибора 2 диод 4 запираетс  и лини  5 зар жаетс  до исходного напр жени .During the breakdown and the occurrence of an electric arc in the device 2, the diode 4 is unlocked and a transient occurs due to the presence of line 5, which leads to the cessation of the electric arc. During the transient process, the device 2 restores the electrical strength. After the restoration of the electrical strength of the device 2, the diode 4 is closed and the line 5 is charged to the initial voltage.

Таким образом, применение устройства дл  защиты электровакуумных приборов , работающих в ключевом режиме, позвол ет обеспечить автоматическое восстановление рабочего режима схемц после пробо  электровакуумных приборов причем вли ние защитного устройства на процесс переключени  электровакуумных приборов исключаетс , что выгодно отличает предлагаемое устройство от прототипа.Thus, the use of a device for protecting electrovacuum devices operating in a key mode allows automatic restoration of the operating mode of the circuitry after the breakdown of electrovacuum devices and the influence of the protective device on the switching process of electrovacuum devices is excluded, which distinguishes the proposed device from the prototype.
