硅橡胶复合套管用FB-PRTV修复后性能分析OA北大核心CSCDCSTPCD
Performance Evaluation for RTV Composite Casing after Renovated by FB-PRTV
硅橡胶复合材料因具有重量轻、优异的耐污性能和防暴性能,硅橡胶复合材料被广泛应用在互感器、断路器及套管等电气设备中.但硅橡胶在表面放电、电晕放电等因素影响下易老化.部分硅橡胶复合套管在运行一定年限后由于环境、电应力和机械应力作用,会出现表面憎水性减弱,伞套脆化、粉化、开裂等劣化现象,最终导致电气绝缘性能下降,易导致高压设备事故和电网事故.硅橡胶复合套管出现老化后,处理办法是返厂重新更换硅橡胶复合套管,但这种方法费时又费力,费用较高.现佛山供电局探索…查看全部>>
Because of its light weight, excellent anti-pollution performance and explosion proof performance,the silicone rubber composite material is widely used in transformers, breakers, bushings and other electrical equipment. However, silicone rubber is easy to get aged under the influence of surface discharge and corona discharge. After a certain duration of years'running, several phenomena will appear in the silicone rubber composite bushings, such as less hydro…查看全部>>
