Product Description

ZN85-40.5kV Indoor Vacuum Circuit Breaker
Overview:

Introducing the ZN85-40.5/T(3AV3) indoor handcart vacuum circuit breaker, this cutting-edge device operates on a three-phase AC 50Hz system with a rated voltage of 40.5kV. Primarily integrated with the KYN61-40.5(Z) switchgear, it stands as a pinnacle of modern power supply and distribution technology. Designed with an emphasis on efficiency and reliability, it caters to the demanding needs of contemporary power systems by ensuring uninterrupted performance.

This innovative circuit breaker boasts a sophisticated upper and lower arrangement structure, significantly minimizing its depth. The main conductive circuit, alongside the vacuum interrupter and its moving/static conductive connections, is securely encased within an insulated tube. Featuring an advanced composite insulation configuration, it distinctly isolates the three-phase arc-extinguishing chambers and their electrified components with unique epoxy insulation casings. This design not only meets stringent air gap and creepage distance standards under regular conditions but also guarantees exceptional reliability and robustness with all primary electrical connections firmly fixed.

Key Features:

1. Composite Insulation Design: This design excels in fulfilling air gap and creepage distance standards while maintaining a harmonious balance with the device's dimensions. The resulting layout is compact, logically structured, and visually appealing.
2. Innovative Operating Mechanism: Tailored specifically for this vacuum circuit breaker, the operating mechanism seamlessly aligns with the vacuum interrupter's specifications, providing unparalleled reliability, an extended operational life, and a maintenance-free experience.
3. Flexible Handcart Design: Featuring a screw-rod push mechanism, it allows for effortless insertion or withdrawal from panels. The inclusion of a robust mechanical interlock ensures the implementation of 'Five Prevention' functions, making it adaptable to diverse operational environments, even under harsh conditions.
