【概要】1. Strong breaking capacity

The SF6 circuit breaker completes the arc blowing by blowing out SF6 gas. Its arc blowing speed is fast, the arc time is short, and the breaking current is large, which is effective

Protect the safety of medium and high voltage circuits. After the SF6 circuit breaker disconnects the capacitor or inductive current, there is no danger of reignition or re-ignition.

2. Long electrical life

Sulfur hexafluoride circuit breakers have a long service life, a long maintenance cycle, and can adapt to frequent operations in a short period of time, with good safety and durability. Sulfur hexafluoride circuit breakers can be opened continuously for 19 times with a full capacity of 50kA, and the cumulative current of the opening has reached 4200kA.

3. High insulation level

Sulfur hexafluoride circuit breakers use sulfur hexafluoride gas as the insulating medium. This gas has a very high insulation level. It can easily pass various insulation experiments under 0.3MPa pressure and has a large margin.

4. Good sealing performance

Sulfur hexafluoride circuit breakers have simple structure and good airtightness. The interrupter, resistor, and pillar are separated into independent gas partitions, and the water content of sulfur hexafluoride itself is relatively low. The installation and maintenance of the SF6 circuit breaker are convenient, and the internal structure of the circuit breaker does not need to be opened, so that the internal structure of the SF6 circuit breaker can be kept well airtight.
