Working Procedure of SF6 Gas 11KV Load Break Switch
The load switch that uses SF6 gas as insulation and arc extinguishing medium is called theSF6 gas load break switch. It can be used to switch and switch load current and overload current, and it can also be used to switch and switch no-load circuits, no-load transformers, and capacitors. Groups, etc., all three-position load switches with the functions of connecting, disconnecting, and grounding have the characteristics of simple structure and low price. But the load switch cannot disconnect the short-circuit current.
Intended Use of SF6 Gas 11KV Load Break Switch
The SF6 load switch is an excellent load switch that many users have experienced in recent years. In addition to its long electrical life and strong braking force, it has the same advantages as the vacuum load switch. Its outstanding advantage is that it is easy to achieve three working positions (connected, disconnection and grounding), small current (inductance, capacitance) breaking, strong resistance to severe environmental conditions. It is suitable for popularization and application in urban and rural medium voltage distribution networks.
Gopoweris one of the earliest high-tech electric power equipment ltdengaged in R&D and production of (12KV-40.5kV) medium-voltage transmission and distribution intelligent control equipment in China.
