What is the Role of SF6 Load Break Switch?

In daily life, we often see the figure of the SF6 load break switch, and its application greatly facilitates our life. So do you know what it does? If you don't know, you might as well follow the load switch manufacturer Gopower to find out.

1. The role of SF6 load break switch

(1) Opening and closing functions

Since the sf6 gas load break switch has a certain arc extinguishing ability, it can play the role of breaking and closing the load current, and at the same time, it can also break and close the rated current.

(2) Substitution effect

Because the SF6 outdoor pole load switch can be used in series with the current limiting fuse to replace the circuit breaker, it can often be used in the application of the circuit breaker. We have 11kv load break switch, and 15 kv pole mounted disconnect switch, and 33kv load break switch.

(3) Main application of load switch

Because the SF6 outdoor column load switch is mainly used to break and close the load current, and it can be used in conjunction with the high-voltage fuse to replace the circuit breaker, its application range has been expanded.

2. Precautions for using SF6 load break switch

(1) When using the SF6 load break switch, make sure that it is installed correctly, and at the same time, the frame, closing mechanism, cable sheath, and protection device of the switch should also be well-grounded.

(2) When the SF6 load break switch is used in conjunction with the fuse, pay attention to the rationality of the combination of the two models to avoid various faults.

(3) Since the SF6 load circuit breaker has no arc extinguishing device, although it can isolate the power supply, it has an obvious disconnection point. It is necessary to pay attention to the normal connection temperature of the equipment during the process of use, and at the same time, the contact is good in the closed state. No-load opening and closing operation test to ensure normal use without abnormal conditions.

(4) When using the SF6 load break switch, it is necessary to do a good job of cleaning, regularly check for dirt, cracks, damage, leakage, and other problems, and pay attention not to wash with water.

To sum up, the SF6 load break switch has many functions, and the application occasions have also expanded. If you have any need, please feel free to consult us.
