Description
(54) СХЕМА ИНДИКАЦИИ ПРОБОЯ ПРОДОЛЬНОЙ ИЗОЛЯЦИИ ВЬГСОКОВОЛЬТНЫХ ОБМОТОК(54) SCHEME OF INDICATION OF THE BREAK-IN OF LONG-TERM ISOLATION
При прохождении фронта волны З по 9 -9 S Ji- P 4opMaTopa или реактора продольна емкость 5 вызывает емкостный пик напр жени , который гаситс включен-/ ным, например, в нейтраль обмотки парал- 5 лельно частотно-зависимому .импедансу н елинейным сопротивлением, и последуюшие за емкостным пиком колебани меньшей амплитуды, чувствительные к пробою, изол ции, воспринимаютс частотно-зави- 10 симым импедансом, содержащим параллель-, но включенные индуктивное сопротивление и конденсатор и регистрирующийс прибором 6, например осциллографом.When the wave front passes through 9-99 Ji-P 4opMaTopa or the reactor, the longitudinal capacitance 5 causes a capacitive peak voltage, which is damped by switching, for example, into the neutral winding parallel to the frequency-dependent impedance and linear resistance, and the smaller amplitude oscillations that follow the capacitive peak, sensitive to breakdown, isolation, are perceived by a frequency-dependent impedance containing a parallel but switched on inductance and a capacitor and recorded by an instrument 6, for example an oscilloscope.
Предмет йзобрёте ни Я Схема индикации пробо продольной изол ции высоковольтных обмоток дл трансформаторов и реакторов при импульсных испытани х, содержаща включенные в нейтраль обмотки параллельно соединенные сопротивление и конденсатор, состаВ л ющие частотно-зависимый импеданс и регистрирующий прибор, о т л и ч а юГщ а с тем, что, с целью повьпиени ее чувствительности, сопротивление в импедансе выполнено индуктивным и пара лельно ему подключено нелинейное сопротивление , например стабиловольт.Subject I choose the diagram of the indication of the breakdown of the longitudinal isolation of high-voltage windings for transformers and reactors with impulse tests, containing parallel-connected windings connected in a neutral resistance and a capacitor, comprising a frequency-dependent impedance and a registering device, which is mt h and with the fact that, in order to control its sensitivity, the impedance resistance is inductive and a nonlinear resistance, for example, a stabilovolt, is connected to it.
