Recently, the domestic electrical equipment sector has witnessed a significant technological break through - the ZND-12X indoor permanent magnet operating mechanism vacuum circuit breaker, newly designed by XDTZ, has been officially released and put on the market. This product deeply integrates permanent magnet operating technology with intelligent control concepts, aiming to provide a switch solution with higher reliability, longer service life and better economy for 12kV power systems. It marks a solid step forward for China in the intelligent and high-performance development of medium-voltage switchgear.
Core technological innovation: The outstanding combination of permanent magnet operation and vacuum arc extinguishing
The core highlight of the ZND-12X lies in its adoption of an advanced permanent magnet operating mechanism, which replaces the traditional spring operating mechanism. This technology utilizes the holding force generated by high-performance permanent magnetic materials, combined with a precise electronic control unit, to achieve the closing and opening operations of the circuit breaker.
01
Equipped with an optimally designed vacuum interrupter
The ZND-12X boasts outstanding short-circuit current breaking capacity and excellent insulation recovery characteristics, ensuring rapid and reliable current interruption in the event of a short circuit, thus safeguarding the safety of power grid equipment and personnel. friendly features.
02
Minimal structure, ultra-high reliability
The number of parts in the permanent magnet mechanism is significantly reduced compared to the spring mechanism, fundamentally lowering the mechanical failure rate and greatly extending the mechanical life. It can easily achieve an operational life of over 100,000 cycles.
03
Maintenance-free, time and labor-saving:
The mechanism requires almost no regular lubrication, adjustment or other maintenance work, significantly reducing the user's operation and maintenance costs and workload, truly achieving a "maintenance-free" design.
04
Flexible Adaptability:
Compact design, it can be used as a fixed installation unit or easily embedded in various mainstream models such as KYN28A metal armored withdrawable switchgear, with strong compatibility and universality.
Market Application and Prospect Outlook
The ZND-12X permanent magnet mechanism vacuum circuit breaker is particularly suitable for applications with high requirements for operational reliability, service life and intelligence level, such as: it is widely used in urban power grids, rural power grids and other power grid construction and product upgrade projects, and is especially suitable for frequent operation applications.
Industry experts say that the launch of ZND-12X not only fills another gap in the domestic high-performance permanent magnet circuit breaker market, but also will drive the entire power distribution equipment industry to a higher technical level. Its features of "reliable, intelligent and maintenance-free" directly address the pain points of current distribution network operation and maintenance, and is expected to become the benchmark choice for the new generation of 12kV voltage level switchgear.
With its wide application, it will surely inject strong impetus into enhancing the power supply reliability, operational efficiency and intelligent level of China's distribution network.
