Description
Technical field
The present invention relates to converter station valve hall monitoring technology fields more particularly to a kind of converter station valve hall particulate matter to monitor on-line
Method, apparatus and system.
Background technique
For converter valve as the core element for converting alternating current to direct current, the requirement for running environment is very strict,
There is stringent explanation not only for environment temperature, the humidity of operation, from operating experience, the cleanliness of entire valve hall is for the change of current
Valve and its attached control unit influence also very huge.
Existing DC transmission system is turned in latching process in monopole by stand-by state, the converter valve exception that rises from all around often occurs
Conduction events, cause of accident are that converter valve TE plate long-play rear surface contamination is serious, are caused under high humility operating condition
Its standby Trigger Function threshold value substantially reduces, and causes to become converter valve abnormal in normal charging process in the change of current.
The humidity control value of change of current station equipment operation should be no more than 60%, and equipment operating environment temperature is also unsuitable excessively high.Valve
Room air particle content (PM2.5, PM10 etc.) is affected to the key equipments operation conditions such as TVM plate, valve block.And by geography
Environment influences, and temperature is high in summer for southern area, and humidity is high under the weather such as Hui Nantian, typhoon, heavy rain.Therefore, O&M people
Member takes the ambient conditions for carving concern valve hall, takes measures when necessary, in the reasonable scope by valve hall environmental Kuznets Curves.
Current monitoring means mainly makes a copy of air-conditioning work station, Hygrothermograph data in valve hall, and by manually carrying out
Analysis.Therefore the problems such as real-time low, find the problem that there are the frequencys of data record is inadequate, while valve hall air particle contains
