<p>PURPOSE: To obtain a synthetic equivalent test method for circuit breaker in which the reclosing/interruption performance can be verified easily using an existing facility upon occurrence of multiplex lighting. CONSTITUTION: A current supply circuit and a Weyl circuit 30 are superposed on a sample circuit breaker 1. A low frequency conduction circuit is inserted between the sample circuit breaker 1 and a circuit for generating a low frequency current by discharging a capacitor 21 to a reactor 22. At the time of test, a low frequency current is fed at first and an arc is generated through opening operation of the sample circuit breaker 1 and the short circuit current is superposed. Subsequently, the auxiliary circuit breakers 6, 26 for the current supply circuit and the low frequency conduction circuit are opened thus operating the Weyl circuit 30 before zero point of the short circuit current. The reclosing/interruption performance is verified through the series of operations upon occurrence of multiplex lightning.</p> |
