HUANG Mengdan, XIAO Chun, YANG Zhining, et al. Research Progress of GIS Equipment Heating[J]. High voltageapparatus, 2020, 56(12): 24-33. DOI: 10.13296/j.1001-1609.hva.2020.12.004.
It’ s difficult to detect the internal faults of gas insulated switchgear(GIS)in time because of its enclosed characteristics.By analyzing the fault of GIS
it ’ s found that the heating problem of GIS is prominent
which often causes the burning of equipment and even the system power failure.By analyzing the heating status
the theoretical studies of heating mechanism and heating detection methods of GIS
the heating progress of GIS was studied.The results show that in order to make the temperature rise calculation accurate and effective
it is necessary to consider the multi-field coupling
which should be combined with the computational complexity and timeliness.On the basis of the heating mechanism of GIS
the detection methods of various heating faults of GIS equipment
such as loop resistance method
infrared temperature measurement method and fiber bragg grating temperature measurement method
are briefly described
and the advantages and disadvantages of each method are compared and analyzed.By discussing the research status and shortcomings of GIS equipment heating
this paper points out the development trend
and provides some guidance for further research on GIS heating.
