11 KV Load Break Switch Working Procedure
The 11KV LBS load switch that uses SF6 gas as insulation and arc extinguishing medium is called the SF6 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 and outdoor pole mounted load break switch groups, among others. 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 11KV LBS 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.
As a reliable electric power equipment company, we will do our best to meet all the needs of customers.
