20120156934 | EXTERNAL CONNECTOR FOR SOLID INSULATED LOAD BREAK SWITCHGEAR - Disclosed is an external connector for a solid insulated load break switchgear. A semi-conductive layer for uniformly distributing an inner field is formed in a body part of a connector to uniformly distribute an inner field. This may prevent partial lowering of an insulating performance of the connector to enhance the insulating performance of the connector. Furthermore, a semi-conductive layer for uniformly distributing an outer field is formed between the connector and a bushing coupled to an upper end of the connector, and between the connector and a plug coupled to a lower end of the connector. This may allow an electric field to be uniformly distributed to a part connected to a ground surface of an arc extinguishing part. | 06-21-2012 |
