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.
