Abstract
The invention provides a charging alarming method and an alarming device of an automatic throw-in equipment of an emergency power supply. When the automatic throw-in equipment of the emergency power supply is charged, a charging mark is detected; when the charging mark cannot be detected, an automatic throw-in allowing mark is detected, if the automatic throw-in allowing mark is successfully detected, whether a first preset time is exceeded is judged, and if the first preset time is exceeded, an alarming signal is given out. The problem of hidden danger of the automatic throw-in equipment of the emergency power supply is solved, and reliability is improved.
Description
[technical field]
The present invention relates to Power System and its Automation technical field, especially relate to a kind of charging alarm method and alarm device of backup auto-activating device.
[background technology]
In electric system, automatic switching device of standby power supply (hereinafter referred to as backup auto-activating device) is indispensable aut.eq., when normal power supply power supply loses power supply capacity because of fault, load is switched to standby power supply by automatically, fast, to keep the continuous power supply to responsible consumer or transformer station.
After charge condition meets, detect busbar voltage, when busbar voltage is fallen or this position of the switch, side of electric power incoming line is in a point position within a certain period of time, and combine when judging that main power supply inlet wire has a pressure without stream and standby power supply line, start backup auto-activating device action, namely first tripping electric power incoming line switch, closes standby power supply service entrance switch after confirmation again.
But, find in actual motion, if backup auto-activating device charges unsuccessfully, or charge successfully, in operational process, because a variety of causes causes it to discharge, after this, all the time charge unsuccessfully because loop or other problems cause device (in fact, actual electric network meets charge condition), in such cases, in fact device fails normally to work, cannot action, and operation maintenance personnel can not grasp this situation in time, bring hidden danger to the safe operation of transformer station.
Prior art backup auto-activating device is unsuccessful owing to charging always, causes device normally to work, and operation maintenance personnel do not know failure of apparatus.After employing the present invention, under device charges unsuccessful situation for a long time, can send alarm signal, remind in time operation maintenance personnel to overhaul device, operations staff can the exception of Timeliness coverage device, overhauls early, improves power supply reliability.
[summary of the invention]
For the deficiency of existing backup auto-activating device technology, the present invention proposes a kind of charging alarm method and device of backup auto-activating device, solve the potential problem of backup auto-activating device charging, improve reliability.
The charging alarm method of backup auto-activating device provided by the invention, comprises step:
When charging to described backup auto-activating device, detect charge flag;
When can't detect charge flag, detecting described prepared auto restart function and allowing mark, if detected, then judging whether more than first schedule time, if exceed described first schedule time, then send alarm signal.
The charging alarm device of backup auto-activating device provided by the invention, comprising:
Pick-up unit, for detecting charge flag when charging to described backup auto-activating device; And when can't detect charge flag, detecting described prepared auto restart function and allowing mark;
For described pick-up unit, alarm device, detects that described prepared auto restart function allows to judge whether more than first schedule time during mark, if exceed described first schedule time, then sends alarm signal.
[accompanying drawing explanation]
Fig. 1 is bus arrangement figure;
Fig. 2 is the logical flow chart of the charging alarm method of backup auto-activating device of the present invention;
Fig. 3 is the theory diagram of the charging alarm device of backup auto-activating device of the present invention.
[embodiment]
Fig. 1 gives the schematic diagram adopting existing typical bus arrangement, Fig. 2 is the backup auto-activating device charge condition logic diagram of the present invention one most preferred embodiment, for the typical transformer station of Fig. 1, namely adopt the standby throwing pattern that a power lead is main power supply line, another power lead is standby power supply line.As adopted, power lead A is main confession, power lead B is for subsequent use, and the charge condition of its backup auto-activating device is:
Device detects that function allows mark, two sections of buses have voltage and bus-tie circuit breaker in co-bit, the outlet switch of power lead A is in co-bit, and the outlet switch of power lead B is in a point position, and the voltage of power lead B circuit has pressure.When above-mentioned condition is set up, time delay a period of time, as an embodiment, such as time delay 5 seconds, charge flag set (in one embodiment, charge flag being put 1), backup auto-activating device charging (step 101).
When charging to backup auto-activating device, detect charge flag (step 102), in one embodiment, can with charge flag=1 as the state that there is this charge flag; If charge flag detected, then first delay predetermined time (such as, the schedule time is 5s) (step 103), then charges (step 104) to backup auto-activating device.When can't detect charge flag, detecting prepared auto restart function and allowing mark (step 105), in one embodiment, mark=1 can be allowed as the state that there is this charge flag by prepared auto restart function.If detected, then judge whether, more than first schedule time (step 106), if exceed described first schedule time, then to send alarm signal (step 107).The length of first schedule time can arrange different numerical value according to different demands, and such as, as an embodiment, first schedule time can be set to 30s.
As an embodiment, step 105 detect described prepared auto restart function allow mark time if there is no prepared auto restart function allow indicate, then cancel alarm.As the further improvement to this embodiment, after sending alarm signal, if there is no prepared auto restart function allows mark, can judge whether more than second schedule time (step 108) further, if more than second schedule time, then cancel alarm (step 110).Equally, the length for second schedule time also can arrange different numerical value according to different demands, such as, second schedule time is set to 5s.
As an embodiment, stop the condition sending alarm signal can also be cancel alarm by the form of manual intervention, when stopping after the reset signal receiving operating personnel sending alarm signal.
Corresponding with the charging alarm method of above-mentioned backup auto-activating device, the present invention also provides a kind of charging alarm device of backup auto-activating device, comprising: pick-up unit and alarm device.Principle of work is as follows:
When charging to described backup auto-activating device, pick-up unit detects charge flag; When can't detect charge flag, detecting described prepared auto restart function and allowing mark; When pick-up unit detects that described prepared auto restart function allows to indicate, alarm device judges whether more than first schedule time, if exceed described first schedule time, then sends alarm signal.As an embodiment, after alarm device can also be worked as and sent described alarm signal, detect described prepared auto restart function and allow mark whether to exist, if there is no, then cancel alarm.
The above embodiment only have expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
