The heater using in reason.
Background technology
The safe and stable operation of combined electrical apparatus (GIS) is most important to power system, is to improve Supply Security, meets and supply
The fundamental requirement of electricity reliability.Combined electrical apparatus (GIS) due to bring into due to insulating part in installation process moisture, adsorbent band
Moisture that the moisture that enters, the new gas of SF6 gas contain, fill the element process such as technique not good, evacuation process is bad, pipe joint
The factor such as not thorough cause combined electrical apparatus (GIS) to put into operation after excessive water content；And owing to SF6 gas leakage point oozes in running
The moisture, the steam that enter are penetrated into by equipment weak seal link and also lead to combined electrical apparatus (GIS) inside inside equipment SF6
SF6 moisturized gas, excessive water content, even result in combined electrical apparatus (GIS) built-in electrical insulation gas breakdown.Once break down, will draw
Play locally even section to have a power failure, affect national economy and produce, destroy the normal order of society, cause the loss being difficult to retrieve.
Part substation location is located in Gobi desert, strong wind area, and annual range of temperature is relatively big, due to by early stage mounting process after putting into operation
And ambient temperature impact causes the internal SF6 moisturized gas of combined electrical apparatus (GIS), excessive water content.The internal SF6 of combined electrical apparatus (GIS)
After gas micro water content exceedes warning value, need periodically carry out micro-water content repetition measurement, inspection, and in time micro-water content is exceeded standard
Air chamber is processed.
To in GIS air chamber excessive water content processing procedure, by our research discovery, temperature changes to the micro-water in air chamber
Content has a major impact.In SF6 gas, the standard of micro-water content uses the volume of steam in SF6 gas and coexists therewith
The ratio of the volume of dry gas.GB is all the measured value at 20 DEG C for the setting of micro-water, and after GIS is heated, SF6 gas
Humidity with application temperature relevant.Molecular thermalmotion is accelerated when temperature is raised, and the moisture of insulating part and adsorbent etc. will be analysed
Go out, enter SF6 gas.
When excessive water content is processed, to allowing for the more thorough of moisture solution after the heating of GIS air chamber, contribute to whole
The reliable of individual processing system is efficiently administered；Current associated heat device is difficult to be directly used in the heating of GIS air chamber, and some employings add
The mode of torrid zone parcel, is difficult to operation, it is impossible to temperature control, is difficult to realize modularization assembling.
