Description

При нормальном режиме работы 1мощных высоковольтных вентилей на нагрузке выдел етс  значительна  мощность (в случае выпр мител  БР 50/120, например, больше 9 мега-ватт) и ноэтому при испытании вентилей требуетс  соответствующа  мощна  аппаратура. В лабораторных услови х обычно невозможно испытывать эти вентили в нормальном дл  них режиме. Известны устройства дл  испытани  высоковольтных вентилей в режимах, не соответствующих реаль1ным услови м их работы, но в некоторых отношени х им эквивалентных. В этих устройствах пр мой ток через вентиль пропускаетс  нутем разр да конденсатора через этот вентиль и через последовательно с ним соединенный дроссель. О братпое напр жение формируетс  нерезар дкой этого конденсатора в пр мой полупериод. Недостатки этих устройств состо т в там, что испытуемый вентиль должен быть об зательно управл емым и что сила пр мого така и величина обратного напр жени   вл ютс  взаимно-зависимыми величинами, поэтому невозможно производить испытание вентил , измен   только одну из этих величин.Under normal operation, 1powerful high-voltage gates exert considerable power on the load (in the case of the BR 50/120 rectifier, for example, more than 9 mega-watts) and therefore, when testing the gates, a corresponding powerful apparatus is required. Under laboratory conditions, it is usually not possible to test these valves in the normal mode. Devices are known for testing high-voltage valves in modes that do not correspond to the actual conditions of their operation, but are equivalent in some respects to them. In these devices, the direct current through the valve is passed through a capacitor discharge through the valve and a series connected choke through it. An overvoltage voltage is formed by not recharging this capacitor in the direct half period. The disadvantages of these devices are there that the valve to be tested must be necessarily controlled and that the direct force and the reverse voltage value are mutually dependent values, therefore it is not possible to test the valve by changing only one of these values.

Предлагаемое устройство позвол ет при сохранении способа получени  пр мого тока и обратного напр жени  при помощи конденсатора и дроссел  иснытывать неуправл емые вентили и мен ть обратное напр жение при неизменной силе тока.The proposed device, while maintaining the method of obtaining direct current and reverse voltage with the help of a capacitor and throttles, tests the uncontrolled valves and changes the reverse voltage at a constant current strength.

Capacitor C is charged before voltage 1 /. in the forward half cycle of voltage with a frequency of 50 hertz. At the time of the brotherly half-period in IMOment / 1, an unlocking positive pulse is applied to the grid of the Tiratron Ti. A capacitor is recharged in an oscillatory circuit consisting of self-induction L, a Tiratron Ti, and a test E. T. valve. Since the losses in the circuit are small, the capacitor recharges to a voltage U. not much less than
