Inventor: MIYAKE NOBUYUKI
IPC: G01R31/327
Filed: 1984-12-27
Abstract: PURPOSE:To obtain a small leading current equivalence tester for a breaker with a lowered cost in a high voltage large current breaker, by connecting a sample breaker in series to an auxiliary breaker to supply current with a prescribed delay value from an AC voltage circuit while DC voltage is applied to the connection of both the breakers immediately after the breaking of the current. CONSTITUTION:Breaking commands are provided to interrupt a sample breaker 5 and an auxiliary breaker 3 at the zero point t2 of breaking current I and causes contacts to open at the time t1. When the breaking current I is interrupted at the time t2, the restriking voltage of the power source side voltage VS begins to rise at the power source side terminal of the sample breaker 5 as it is delay current. At the time t3 immediately after the interruption of the current, a startup gap section 19 controlled with a startup controller 21 having a zero detector 21a and a startup discharge needle 21b is started and charges a waveform adjusting capacitor 17 with DC voltage VD to apply a voltage Em. As the DC voltage VD reaches the peak value Em with the transient vibration of the power source side voltage VS gone, the interpole voltage VT of the sample breaker 5 gives almost Em(1-cosomegat), showing the same voltage waveform as that when the small leading current is interrupted and thus, will rise up to 2Em.
