摘　　要：气体绝缘金属封闭开关设备(GIS),由于其封闭特性,内部故障难以及时检测。对GIS设备的故障进行分析,发现GIS的发热问题突出,常造成设备烧毁甚至系统停电。通过分析GIS设备的发热现状,发热理论研究和发热检测方式,研究GIS设备的发热进展。结果表明要使温升计算精确有效,需要考虑多场耦合,且考虑因素应与计算复杂度、时效性相结合。在GIS设备发热机理的基础上,简述了GIS设备的各发热故障检测方法,如回路电阻法、红外测温法和光纤光栅测温,并进行对比分析,得到各方法的优缺点。通过讨论GIS设备发热的研究现状及不足,指出了发展趋势,为进一步研究GIS设备发热情况提供一定的指导。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.
