Abstract
Stop repair method electric power wink and stop in wink to select reclosing circuit, it includes bus and at least one branch line, time relay normal open switch is equipped with every branch line, described time relay normal open switch is connected in series with current transformer, auxiliary reclay, auxiliary reclay normally-closed contact is connected in parallel on the two ends of time relay normal open switch and auxiliary reclay, the auxiliary reclay normally-closed contact series connection time relay.Beneficial effects of the present invention are：Can be according to the time that open-circuit operation is switched be checked, so as to determine whether faulty line in brain comprehensive platform.The power-off time of this process faultless circuit is shorten to 15 seconds, is that society reduces power off time.
Description
Technical field
The present invention relates to stop in the wink of power system to select reclosing device, and in particular to a bus drives multiple branch lines
Stop in wink select reclosing device.
Background technology
Current China 110KV and following transformer station largely have been realized in integrating self-protection, in the line provided with weight
Close a floodgate.According to statistics, the failure for having 10% is permanent failure, it is necessary to manual maintenance.It is by one in many local transformer stations
Bus drives multiple sub-line circuits, in busbar grounding, it is impossible to directly judge it is which root line line failure.Use
Method, which is still, stops to be grounded selection in traditional wink, i.e., according to the order prearranged, circuit is disconnected one by one, and event is checked after disconnection
Whether barrier disappears, then in power transmission.This process is generally required 1-3 minutes, and so artificial causes stopping for fault-free circuit
Electricity.Modern society so investigates to the dependence more and more higher of electricity consumption and causes loss to society.
The content of the invention
Stop selection wink it is an object of the invention to provide a kind of less to 1-5 seconds of time for the investigation failure for making sub-line circuit
Reclosing device.
Technical scheme is specially：
Stop in wink to select reclosing circuit, it includes being equipped with the time on bus and at least one branch line, every branch line
Relay normally open is switched, and described time relay normal open switch is connected in series with current transformer, auxiliary reclay, centre after
Electrical equipment normally-closed contact is connected in parallel on the two ends of time relay normal open switch and auxiliary reclay, the series connection of auxiliary reclay normally-closed contact
The time relay.
Described current transformer is connected with remote controllers.
Current transformer is connected with data display unit.
A kind of electric power wink stops repair method, and it comprises the following steps：
1., during normal work, time relay normal open switch is kept closed, and auxiliary reclay is constantly in obtain electric shape
State, its auxiliary reclay normally-closed contact disconnects, branch line normal work；
When 2., overhauling, time relay normal open switch is cut off, auxiliary reclay dead electricity, auxiliary reclay normally-closed contact
Maintain original closure state；If branch line fault-free, the time relay obtains electric, after one section of interval time, time relay
Device normal open switch is closed；If branch line failure, the time relay still can not obtain electric, then time relay normal open switch continues
Disconnect.
Described interval time is 1-5s.
Beneficial effects of the present invention are：The time that can be switched in brain comprehensive platform according to inspection open-circuit operation, so that
Determine whether faulty line.The power-off time of this process faultless circuit is shorten to 1-5 seconds, when being that society reduces power failure
Between.
Brief description of the drawings
Fig. 1 is the schematic diagram of the present invention.
Embodiment
As shown in figure 1, stopping in a kind of wink to select reclosing circuit, it includes the branch line 2 of bus 1 and at least one, every branch
Time relay normal open switch 3 is equipped with circuit, time relay normal open switch 3 here serves as open-circuit operation switch.
Above-mentioned time relay normal open switch 3 is connected in series with current transformer 7, auxiliary reclay 5, auxiliary reclay
Normally-closed contact 4 is connected in parallel on the two ends of time relay normal open switch 3 and auxiliary reclay 5, and auxiliary reclay normally-closed contact 4 is connected
The time relay 8.
Above-mentioned current transformer 7 is connected with remote controllers, facilitates long-range staff to be monitored in real time.
Above-mentioned current transformer 7 is also connected with data display unit, and the staff at convenient scene obtains current number
According to.
A kind of electric power wink stops repair method, and it comprises the following steps：
1., during normal work, time relay normal open switch 3 is kept closed, and auxiliary reclay 5 is constantly in electric
State, its auxiliary reclay normally-closed contact 4 disconnects, branch line normal work；
When 2., overhauling, time relay normal open switch 3 is cut off, the dead electricity of auxiliary reclay 5, auxiliary reclay is normally closed to be touched
Point 4 maintains original closure state；If branch line fault-free, the time relay 8 obtains electric, after one section of interval time, the time
Relay normally open switch 3 is closed；If branch line failure, the time relay 8 still can not obtain electric, then the time relay is normally opened opens
3 are closed to continue to disconnect.
Described interval time is 1-5s.
So, when overhauling sub-line circuit, if branch line has trouble point 6, the time relay 8 still can not be obtained
Electricity, the then continuation of time relay normal open switch 3 disconnects；If failure is not present in branch line, the time relay 8 obtains electric, through one section
After interval time, time relay normal open switch 3 is closed, when such operations staff checks in the remote interface of comprehensive automation
Between relay normally open switch 3 turn-off time, if having involution phenomenon, with regard to can judge branch line whether failure.
Above-described is only the preferred embodiment of the present invention, it is noted that for those skilled in the art,
Under the premise of general idea of the present invention is not departed from, some changes and improvements can also be made, these should also be considered as the present invention's
Protection domain.
