to carry out, this process need manual operation.When ac circuit dead electricity, dead electricity relay contact disconnects, and now, the coil of the first open type D.C. contactor 11 and the first closed type D.C. contactor 12 is in off-position rapidly, first open type D.C. contactor 11 main contacts is normally closed, and the first closed type D.C. contactor 12 main contacts is often opened.No matter storage battery is in normal operation or discharge test or inner walkway or other states, and batteries 2 all can disconnect other loops, recovers to be connected with main bus bar 6, powers, to ensure visual plant not power-off to main bus bar 6.Leave on-line monitoring system main frame 5 certain hour for and recover battery-driven order to detect communication and to assign other loops of correct disconnection.When on-line monitoring system main frame 5 monitors any abnormality, in the case of necessary, directly can issue an order, control trigger element 23 is threaded off, thus make the overall power-off of long-range discharge controller 4, safe and reliable to ensure.
Last it is noted that above embodiment is only in order to illustrate technical scheme of the present invention, be not intended to limit; Although with reference to previous embodiment to invention has been detailed description, it will be understood by those of skill in the art that it still can be modified to the technical scheme described in previous embodiment, or wherein portion of techniques feature is replaced on an equal basis; And these amendments or replacement, do not make the essence of appropriate technical solution depart from spirit and the scope of various embodiments of the present invention technical scheme.
