Description

Предлагаемое устройство дл  испытани  выключателей на отключающую способность отличаетс  от известных тем, что испытуемый пыключатель подключен к источнику тока через управл емый двухполупериодный ионный выпр митель, в цепь которого включено индуктивное сопротивление. Управл ющие импульсы на вентили этого выпр мител  подаютс  в такие моменты времени, чтобы минимальное значение тока, проход щего через выключатель, было достаточным дл  поддержани  в нем дуги.The proposed device for testing breakers for breaking capacity differs from those known in that the test switch is connected to the current source through a controlled full-wave ion rectifier, in the circuit of which inductive resistance is connected. Control pulses are applied to the valves of this rectifier at such times that the minimum value of the current passing through the switch is sufficient to maintain an arc in it.

На чертеже изображена принципиальна  схема предлагаемого устройства .The drawing shows a schematic diagram of the proposed device.

Испытуемый выключатель / (а при испытани х в синтетических схемах также и последовательно с ним соединенный вспомогательной управл емый выключатель 2) подключаетс  к тра 1сформатору 3 через двухполупериодный ионный выпр митель, содержащий два вентил  4 и 5. Трасформатор 3 питаетс  от синхронного генератора 6 ударной мощности .The test switch / (and, when tested in synthetic circuits, the connected auxiliary control switch 2 connected in series with it) is connected to the 1c transformer 3 via a full-wave ion rectifier containing two valves 4 and 5. The transformer 3 is powered by a synchronous generator of 6 shock power .

Путем соответствуюнхего выбора моментов зажигани  вентилей 4 н 5 выпр мител  обеспечиваетс  минимальна  величина тока, при которой поддерживаетс  горение дуги в испытуемом выключателе / и во вспомогательном выключателе 2 (при испытании по синтетическим схемам).By appropriately selecting the starting points for the 4 n 5 rectifier valves, the current is minimized at which the arc is maintained in the test switch / and in the auxiliary switch 2 (when tested in synthetic schemes).

Таким образом, предлагаемое устройство позвол ет обеспечить протекаиие тока через испытуемый выключатель в течение требуемого числа полупериодов.Thus, the proposed device allows current to flow through the test switch for the required number of half periods.

Дл  повьннени  устойчивости горени  дуги в выключателе последовательно с ним может быть включена дополнительна  индуктивность.In order to impair the stability of the arc in the switch, additional inductance may be connected in series with it.

№ 119261- 2 -No. 119261-2 -

тем, что, с целью его упрощени , испытуемый выключатель подключен к источнику тока через двухполупериодный ионный выпр митель, о цепь которого включено индуктивное сопротивление, и минимальное значекие тока, необходимое дл  поддержани  дуги в выключателе, обеспечиваетс  соответствующим выбором момента зажигани  вентилей .In order to simplify it, the test switch is connected to a current source through a full-wave ion rectifier, the circuit of which inductive impedance is connected, and the minimum value of current required to maintain the arc in the switch, is ensured by appropriate selection of the valve ignition time.
