Study of compatibility between eco-friendly insulating medium C
Due to its excellent insulation properties, the insulating medium C6F12O has been considered as a potential eco-friendly gas to use in medium and low voltage switchgear. To determine their long-term behavior, intensive investigations about the compatibility between C6F12O and sealing rubber material...

| 520 | |a Due to its excellent insulation properties, the insulating medium C6F12O has been considered as a potential eco-friendly gas to use in medium and low voltage switchgear. To determine their long-term behavior, intensive investigations about the compatibility between C6F12O and sealing rubber materials used in electric equipment has been developed. The surface morphology and element changes of EPDM before and after the test are revealed based on scanning electron microscope and X-ray photoelectron spectroscopy. Meanwhile, the interaction mechanism between EPDM and C6F12O is simulated based on molecular dynamics theory. It is found that EPDM is incompatible with C6F12O after 280 days. There exist chemical reactions between EPDM and C6F12O, resulting in the precipitation of white crystal particles and the increase of F element from 0.480% (10 days) to 3.480% (280 days) on the surface of EPDM. Meanwhile, the calculation results show that the solubility parameter of SF6 and C6F12O are 18.730 (J/cm3)1/2 and 13.454 (J/cm3)1/2, which reveals that C6F12O is easier to dissolve with EPDM. The diffusion coefficient of C6F12O in EPDM (5.100 × 10−7 cm2/s) and the interaction energy (42.703 kcal/mol) are also higher than those of SF6, which makes it easier for C6F12O to diffuse around and inside EPDM. These results can provide theoretical and technical reference for the material selection and design of C6F12O gas insulated equipment. | ||

To determine their long-term behavior, intensive investigations about the compatibility between C6F12O and sealing rubber materials used in electric equipment has been developed. The surface morphology and element changes of EPDM before and after the test are revealed based on scanning electron microscope and X-ray photoelectron spectroscopy. Meanwhile, the interaction mechanism between EPDM and C6F12O is simulated based on molecular dynamics theory. It is found that EPDM is incompatible with C6F12O after 280 days. There exist chemical reactions between EPDM and C6F12O, resulting in the precipitation of white crystal particles and the increase of F element from 0.480% (10 days) to 3.480% (280 days) on the surface of EPDM. Meanwhile, the calculation results show that the solubility parameter of SF6 and C6F12O are 18.730 (J/cm3)1/2 and 13.454 (J/cm3)1/2, which reveals that C6F12O is easier to dissolve with EPDM.

Study of compatibility between eco-friendly insulating medium C |
| abstract |
Due to its excellent insulation properties, the insulating medium C6F12O has been considered as a potential eco-friendly gas to use in medium and low voltage switchgear. To determine their long-term behavior, intensive investigations about the compatibility between C6F12O and sealing rubber materials used in electric equipment has been developed. The surface morphology and element changes of EPDM before and after the test are revealed based on scanning electron microscope and X-ray photoelectron spectroscopy. Meanwhile, the interaction mechanism between EPDM and C6F12O is simulated based on molecular dynamics theory. It is found that EPDM is incompatible with C6F12O after 280 days. There exist chemical reactions between EPDM and C6F12O, resulting in the precipitation of white crystal particles and the increase of F element from 0.480% (10 days) to 3.480% (280 days) on the surface of EPDM. Meanwhile, the calculation results show that the solubility parameter of SF6 and C6F12O are 18.730 (J/cm3)1/2 and 13.454 (J/cm3)1/2, which reveals that C6F12O is easier to dissolve with EPDM. The diffusion coefficient of C6F12O in EPDM (5.100 × 10−7 cm2/s) and the interaction energy (42.703 kcal/mol) are also higher than those of SF6, which makes it easier for C6F12O to diffuse around and inside EPDM. These results can provide theoretical and technical reference for the material selection and design of C6F12O gas insulated equipment. |
