A kind of.
The utility model use front, staff pass through controller send meet power equipment operation when minimum voltage number
According to this and maximum voltage data is to comparing module, as the predetermined minimum in comparing module, preset maximum value,
Two comparison value of real-time detection gained magnitude of voltage when predetermined minimum, preset maximum value are run for power equipment.
When the utility model uses, the distributed Partial Discharge Detection early warning system of this high-tension switch cabinet, first pass through voltage
The detection to high-tension switch cabinet shelf depreciation for the transformer, then by controller, comparing module, feedback module and microprocessor
The cooperation of device, real-time detection gained voltage data value is compared with predetermined minimum, maximum, if showing after comparing, real
When detection gained voltage data value be less than predetermined minimum or exceed preset maximum value, then show that this equipment has shelf depreciation
Phenomenon, then buzzing alarming is sent by microprocessor driven buzzer siren, remote alarms are carried out by wireless router simultaneously,
Make the timely Awareness status of staff, reach the effect that can reduce accident generation.
In sum：Whether the distributed Partial Discharge Detection early warning system of this high-tension switch cabinet, can detect power equipment
There is the phenomenon of shelf depreciation, if shelf depreciation situation in power equipment, sent by microprocessor driven buzzer siren
Buzzing alarming, carries out remote alarms by wireless router simultaneously, makes the timely Awareness status of staff, reaches and can reduce accident
The effect occurring.
While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art,
