The intelligent leakage controller system and the selective reclosing method provided by the invention have the advantages that the reclosing function can be opened or closed by the programmer or upper computer according to the type of the failure, the relevant reclosing time can be adjusted, the power supplying property is improved, and the control to the controller is more intelligent.
Description
Technical field
The present invention relates to intelligent leakaging controller system, particularly relate to a kind of intelligent leakaging controller system and selectivity reclosing method thereof of whether selecting locking according to fault type.
Background technology
Reclosing is meant circuit breaker after breaking down, the process that automatic time delay closes a floodgate under the situation that does not need manual intervention.
Cause the lightning protection action of a lot of equipment because of weather weather reason of changes; the residual current circuit breaker tripping operation, a lot of visual plants have also stopped work, have only the arrival of waiting for the attendant; this common transient fault has had a strong impact on the steady operation of the network equipment, causes economic loss.
Existing intelligent leakaging controller system has only electric leakage reclosing function, occurs leak current fault in circuit, circuit breaker trip, if circuit breaker is operated under the fixed shelves pattern, circuit breaker closes a floodgate again, but reclosure time is non-adjustable between 20～60S.
Therefore, if when overvoltage, under-voltage or other faults appear in circuit breaker, circuit breaker can't reclosing.When even leak current fault occurring, electric leakage reclosing function also can't be closed, and the reclosure time user also can't adjust.
Summary of the invention
The purpose of this invention is to provide a kind of intelligent leakaging controller system and selectivity reclosing method thereof, this intelligence leakaging controller system can open or close the reclosing function according to the different faults type selecting, and reclosure time is adjustable.

Among the present invention, described fault type comprises: (1) residual current fault (2) residual current mutation failure (3) overload under-voltage fault of long delay fault (4) short time delay fault (5) current imbalance fault (6) overvoltage fault (7) (8) Voltage unbalance fault (9) peak frequency fault (10) minimum frequency fault (11) temperature fault.
Among the present invention, described reclosure time is divided into 20s, 40s or 60s.
The present invention also discloses the selectivity reclosing method of a kind of intelligent leakaging controller system simultaneously, comprises the steps:
A, the fault type that controller occurs is classified, this fault type comprises: (1) residual current fault (2) residual current mutation failure (3) overload under-voltage fault of long delay fault (4) short time delay fault (5) current imbalance fault (6) overvoltage fault (7) (8) Voltage unbalance fault (9) peak frequency fault (10) minimum frequency fault (11) temperature fault, and this adjustable reclosure time is 20s, 40s or 60s;
B, controller opens or closes the reclosing function according to fault type by programmable device or host computer, and this reclosing function is associated with fault type.
The beneficial effect that the present invention has: intelligent leakaging controller system of the present invention and selectivity reclosing method thereof can open or close the reclosing function by programmable device or host computer according to fault type, and its relevant reclosure time is adjustable, improved power supply reliability, improved power supply reliability, made to the control of controller intelligent more.
