What is SF6 Gas Load Break Switch？
The load break switch SF6 is an excellent switch that many users have experienced in recent years. In addition to its long electrical life and strong braking force, SF6 LBS load break switch has the same advantages as the vacuum load switch. The outstanding advantage of pole mounted load break switch 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. Load break interrupter switch is suitable for popularization and application in urban and rural medium voltage distribution networks.
How does load break switch work?
SF6 gas load break switch is a kind of switch equipment with a simple arc extinguishing device. The load switch that uses SF6 gas as insulation and arc extinguishing medium is called the SF6 load switch. SF6 load break switch can be used for closing and breaking load current and overload current, or as for closing and breaking no-load circuits, no-load transformers and capacitor banks. All three-position load break switch functions are connecting, disconnecting, and grounding have the characteristics of simple structure and low price.
What is the difference between disconnect switch and circuit breaker?
The circuit breaker has an arc extinguishing device, so the circuit breaker can be operated with load, not only can operate the load current but also operate the fault (short-circuit) current; and the disconnect switch does not have an arc extinguishing device, although the regulations stipulate that it can be operated at a load current less than in the case of 5A, it cannot be operated under load as a whole.
The circuit breaker has a good packaging form, so simply observing the circuit breaker cannot intuitively determine whether it is in the closed or open position. The disconnect switch has a simple structure, and its operating status can be seen at a glance from the appearance, and there is an obvious disconnection point during maintenance.
Circuit breakers are mostly operated by remote electric control, while disconnect switches are mostly operated manually on site
SF6 Load Break Switch Advantages
The excellent insulation and arc extinguishing performance of SF6 gas makes the SF6 load circuit breaker have the following advantages: strong breaking capacity, high fracture voltage, and more continuous breaking times. SF6 load circuit breaker is suitable for frequent operation. Load break switch SF6 is a "maintenance free" circuit breaker with excellent performance. SF6 load circuit breaker has low noise, no fire hazard and low electromechanical wear. If you want to know more about medium voltage load break switch, you can download load break switch manual on our website.
The SF6 load switch + fuse combination appliance is the SF6 load switch to bear the overload current (this overload current is still within the range of the load switch rated breaking current for the SF6 load switch) and the closing and breaking of the normal operating current. And it is also required to undertake the breaking of "transfer current". The short-circuit protection and overload protection on the high-voltage side of the transformer are undertaken by the high-voltage current-limiting fuse. At this time, a set of SF6 load switches and three fuses with triggers, as long as any one of the triggers is activated, its linkage mechanism will automatically open the load switches at the same time. The organic combination of the two can meet the requirements of various normal and fault operation protection of the power distribution system.
