12KV VS1 Indoor Medium Voltage Vacuum Circuit Breaker For HV Switchgear
General
VS1-12 Series Indoor AC HV Vacuum Circuit Breaker is an indoor HV switchgear of three AC 50Hz and rated voltage 12kV. Circuit breaker can be proceeded frequent operation and has many times breaking and rapid reclosure capacity, and has reliable interlock function. The device is front and back split charging structure, not only as a fixed installation unit but also match handcart unit with base plate cart.
1. Much technical advancement
a. It adopt the latest effect vacuum arc principle, has strong
breaking capacity, small volume closure at present.
b. Extreme high Electrical endurance, breaking rated current time can arrive 20000 times, breaking short-circuit time is 50 times (40kV is 30 times, 50kA is 20 times).
c. Vacuum arc-extinguishing chamber and operating mechanism
arrange front and back. It reduces energy consumption and noise,
and operation is much more reliable.
d. Compact structure and small volume.
2. Excellent reliability on operation
a. Every detail considers fully domestic condition and requirements in standards during design.
b. Every drive disk assemble part is made of high wear-resistant material mainly, and painted with fine lubrication. It can operate for a long time without additional lubrication and adjustment.
c. Reliable interlock function to prevent various kinds of
mis-operation effectively, it is much more safety for body.
3. Prominent economy on purchase
a. Equipment purchased has high performance cost ratio.
b. Extremely little maintenance cost greatly reduces the operating cost.
c. Excellent common performance reduces design difficulty of the
project.
d. Steady technology, and without environment pollution.
