<p>PURPOSE:To make it possible to produce good 4-parameter restriking voltage and simplify the handling by simultaneously charging various condensers constituting a voltage source circuit with DC high voltage in the condition where the sample breaker layer is closed. CONSTITUTION:The current source circuit consists of low-voltage large-current source 1, protective breaker 2, closing switch 3, reactor 4, auxiliary breaker 5, sample breaker 6 and surge condenser 7. On the other hand, the voltage source circuit consists of a series-connected circuit consisting of condenser 10 and reactor 10 as a voltage source, a series circuit consisting of condenser 11 and resistor 12, a circuit consisting of discharge control gap 8, a circuit consisting of condenser 13, resistor 14 and reactor 15, and a series connected circuit consisting of condenser 16 and resistor 17, which is to become a voltage source. At the time of starting break test, under the condition where the sample breaker is closed, the condenser of the voltage source circuit can be simultaneously charged with DC high voltage.</p> |
