Product Description

ZN85-40.5kV Indoor Vacuum Circuit Breaker
Overview:

Introducing the ZN85-40.5/T(3AV3), a cutting-edge indoor handcart vacuum circuit breaker. Engineered as a three-phase AC 50Hz marvel with a rated voltage of 40.5kV, it is seamlessly integrated into KYN61-40.5(Z) switchgear systems. This next-generation device is crafted to elevate power supply and distribution, setting new standards for efficiency and reliability in contemporary power ecosystems.

This circuit breaker boasts an innovative upper and lower arrangement design that adeptly minimizes the breaker's depth. Encased within an insulated tube, the main conductive circuit, vacuum interrupter, and moving/static conductive connections are expertly configured. Its sophisticated composite insulation framework efficiently isolates the three-phase arc-extinguishing chambers and its electrified components, utilizing distinct epoxy insulation casings. This ensures full compliance with air gap and creepage distance standards under typical conditions. The fixed primary electrical connections are a testament to its exceptional reliability and enduring performance.

Key Features:

1. Composite Insulation Design: Masterfully crafted to meet air gap and creepage distance standards while optimizing device dimensions. The layout is not only compact and rational but also visually appealing.
2. Innovative Operating Mechanism: Tailored specifically for this vacuum circuit breaker, the mechanism aligns seamlessly with the vacuum interrupter’s characteristics, delivering superior reliability, a prolonged lifespan, and operation that requires zero maintenance.
3. Flexible Handcart Design: Features an advanced screw-rod push mechanism that facilitates effortless panel insertion or withdrawal. It is equipped with a robust forced mechanical interlock to activate the 'Five Prevention' functions, making it ideal for diverse and challenging operational environments.
