The mother of the present utility model inspection synchronization function control device that closes a floodgate can be realized four kinds of combined floodgate modes, is respectively on the spot not synchronizing close, not synchronizing close, remote control synchronizing close of synchronizing close, remote control on the spot.The specific implementation process of closing a floodgate with regard to these four kinds of modes respectively is below explained in detail.
1, synchronizing close not on the spot
Here comprise on the spot the operation of protective device panel operation and high-tension switch cabinet switch knob.The key that has a distant place/on the spot on protective device panel on the spot, is a distant place in the time of vertically when key level.The operation of high-tension switch cabinet switch knob refers to that a distant place/selector switch is beaten at " on the spot " state, by switch knob operating breaker on the spot.In loop, using after the connecting with switch knob contact with regard to position contact of the selector switch of a distant place/on the spot, be linked in the lump protective device as input contact; The same period/non-same period, the position contact same period of selector switch was linked into protective device as input contact; The same period/non-same period, the non-same period of the position contact of selector switch was linked into protective device as input contact, and " same period, condition did not meet " meets negate by the defencive function condition same period and realize.
Concrete implementation procedure is: protective device panel operation or high-voltage board operate in regard to position; the same period/non-same period, selector switch was in " the non-same period " position, when two periods of busbar voltage non-same periods etc., 3 conditions met simultaneously, by the outlet of the first protective device, closed a floodgate.
2, synchronizing close on the spot
Comparing with non-Switching Synchronization on the spot, only have a condition difference, is that two sections of busbar voltage conditions same period meet here.Condition met and to comprise the same period: voltage amplitude value difference, voltage phase difference, difference on the frequency are in setting range.Condition met and to be completed by defencive function the same period.Its logical AND on the spot non-Switching Synchronization is slightly different.
Concrete implementation procedure is: protective device panel operation or high-voltage board operate in regard to position, the same period/non-same period selector switch in " the non-same period " position, when two periods of busbar voltage same periods etc., 3 conditions met simultaneously, by the outlet of the second protection unit, close a floodgate.
3, remote control synchronizing close not
The remote control here refers to the closing operation of supervisory control system to bus.For straighforward operation, on logic arranges, there is a difficult point, in order to guarantee the accuracy of straighforward operation, generally, can select two order contacts of band feedback to export the lock that suits that carries out circuit breaker.Two order contacts of band feedback refer to that separating brake, closing operation are sent by an order in supervisory control system; when being 1, this order closes a floodgate; it is 0 o'clock separating brake; with a pair of circuit breaker normally-open normally-close contact, be linked in the input contact of protective device as the feedback signal of this order accordingly, the implementation status of this order is checked.From above narration, can find out, no matter be order or feedback, it is all a pair of cutting closing operation, and only need here, is the order that a remote control is closed a floodgate, and this just need to do the order that logic suits lock remote control and separate.
Concrete implementation procedure is: on protective device panel " distant place/on the spot " key in the distance position, supervisory control system send out remote control and close a floodgate order, the same period/non-same period selector switch in " the non-same period " position, when two periods of busbar voltage non-same periods etc., 4 conditions met simultaneously, by the outlet of the 3rd protective device, close a floodgate.
4, remote control synchronizing close
With remote control non-Switching Synchronization, comparing, only have a condition difference, is that two sections of busbar voltage conditions same period meet here.Condition met and to comprise the same period: voltage amplitude value difference, voltage phase difference, difference on the frequency are in setting range.Condition met and to be completed by defencive function the same period.Its logical AND remote control non-Switching Synchronization is slightly different.
Concrete implementation procedure is: on protective device panel " distant place/on the spot " key in the distance position, supervisory control system send out remote control and close a floodgate order, the same period/non-same period selector switch in " same period " position, when two periods of busbar voltage same periods etc., 4 conditions met simultaneously, by the outlet of the 4th protective device, close a floodgate.
