Product Description

ZN85-40.5kV Indoor Vacuum Circuit Breaker
Overview:

The ZN85-40.5/T(3AV3) indoor handcart vacuum circuit breaker is an advanced three-phase AC device operating at 50Hz with a rated voltage of 40.5kV. It is widely implemented in the KYN61-40.5(Z) switchgear, representing the new generation of power supply and distribution technology. Designed for unmatched efficiency and stellar reliability, it plays a critical role in modern power systems.

This groundbreaking circuit breaker boasts an innovative upper and lower arrangement structure, substantially minimizing its depth. The core conductive circuit, along with the vacuum interrupter and moving/static conductive connections, are encapsulated in an insulated tube. The pioneering composite insulation structure deftly separates the three-phase arc-extinguishing chambers and interconnected electrified components using independent epoxy insulation casings. It adheres to air gap and creepage distance standards under normal operating conditions. All primary electrical junctions are securely fixed, promising exceptional reliability and prolonged durability.

Key Features:

1. Composite Insulation Design: This design ensures adherence to air gap and creepage distance standards while optimizing device dimensions for a compact and aesthetically pleasing layout.
2. Innovative Operating Mechanism: Masterfully crafted for this vacuum circuit breaker, the mechanism aligns seamlessly with the vacuum interrupter's attributes, providing unmatched reliability, extended operational life, and maintenance-free performance.
3. Flexible Handcart Design: The incorporation of a screw-rod push mechanism facilitates effortless panel insertion or extraction. It includes a robust mechanical interlock that activates "Five Prevention" functions, rendering it adaptable for a wide range of operational settings, including challenging environments.
