<p><P>PROBLEM TO BE SOLVED: To perform a test of a circuit breaker including a sequence of a control circuit, prior to trial run of an auxiliary machine, without depending on the combination of the auxiliary machine and the control circuit of the breaker. <P>SOLUTION: A test support device is stored in a case and is used for operation test of a low pressure air circuit breaker of draw-out type which provides a circuit-disconnecting position and a sequential test position according to the amount of drawn-out from a connection position at which electrical connection is made to an auxiliary machine to be protected. The test support device includes: a fixing part that is fixed in the case; and a press-down part which, if the fact that the low pressure air circuit breaker is at the test position is detected when a first position detection switch arranged in the case is pressed down by a part of the low pressure air circuit breaker, presses down a second position detection switch which is arranged in the case and detects the fact that the low pressure air circuit breaker is at the connection position when pressed down by a part of the low pressure air circuit breaker. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
