Abstract

The nozzle will be eroded by the arc in case of interruption of SF

switchgear. The degree of nozzle ablation is closely related to the SF

decomposition products. However

the characteristic products of nozzle ablation under the condition of arc discharge are not clear

which seriously restricts the application of SF

decomposition product analysis method in fault diagnosis. In order to explore the characteristic products of nozzle ablation and its relationship with arc energy

an arc discharge test platform is set up based on 40.5 kV SF

circuit breaker. The arc discharge tests in SF

and He atmosphere are performed under the condition of installation and removal of the nozzle. The gas after the interruption tests is qualitatively and quantitatively detected and analyzed by gas chromatography. It is found after 10 times of interruption test at 5 kA that CF

and CO

produced by nozzle ablation in SF

atmosphere account for 99.8%

77.1%and 70.3%of the total generation respectively

and C

produced by nozzle ablation in He atmosphere accounts for 100%of the total generation. Therefore

and CO

are suitable as indicators to characterize the degree of nozzle ablation. Furthermore

the correlation degree with nozzle ablation from strong to weak is CF

≈C
