The new generation of vacuum circuit breaker Vmini is a perfect combination of reliable new vacuum interrupter R&D and manufacturing technology, intelligent solutions and advanced operating mechanism R&D, design and production technology.
(1) New nylon insulated pole:
New type of vacuum interrupter—Using specially designed contact
geometry and contact material, as well as short arcing time and
very low arc voltage, the contact ablation degree is very low, and
the long life of the arc extinguishing chamber is guaranteed . The
pole shell made of injection-molded nylon material is more
environmentally friendly than epoxy resin and has a lower
manufacturing cost. Innovative insulating materials can be recycled
and reused and the recycling procedure is very simple. Its
decommissioning cost is much lower than traditional epoxy resin
pole
(2)New integrated operating mechanism:
Simplified transmission design mechanism, the cam directly drives
the main shaft, reducing transmission links and improving
transmission efficiency. The mechanism components are
multi-functionally integrated and optimized, and the number is
simplified, with only 65 parts, high reliability, and the mechanism
has its own opening spring and opening buffer to reduce the opening
rebound. The manual energy storage handle of the mechanism is
common to the handle of the chassis vehicle, reducing tools; during
use, the replacement of damaged electrical components does not
involve mechanical transmission parts, and the overall performance
of the product is not affected; combined with high-performance,
long-life lubricants and high resistance The corrosive surface
treatment prolongs the product maintenance cycle and reduces
maintenance costs.
