Product Description

ZN85-40.5kV Indoor Vacuum Circuit Breaker
Overview:

Introducing the ZN85-40.5/T(3AV3) indoor handcart vacuum circuit breaker, a state-of-the-art three-phase AC 50Hz device boasting a rated voltage of 40.5kV. This cutting-edge breaker is extensively utilized within KYN61-40.5(Z) switchgear, marking a new era in power supply and distribution. Engineered for unparalleled efficiency and dependability, it seamlessly integrates into modern power systems, setting a new standard for excellence.

This revolutionary circuit breaker showcases a sophisticated upper and lower arrangement structure, effectively minimizing the breaker’s depth. It houses the main conductive circuit, vacuum interrupter, and both moving and static conductive connections within a meticulously insulated tube. With its pioneering composite insulation structure, it meticulously segregates the three-phase arc-extinguishing chambers and their electrified components, employing independent epoxy insulation casings. This design ensures adherence to air gap and creepage distance standards under regular conditions, culminating in supreme reliability and longevity as all primary electrical connections are steadfastly fixed.

Key Features:

1. Composite Insulation Design: This feature guarantees strict compliance with air gap and creepage distance standards, while concurrently optimizing the device's dimensions. Its layout is not only compact and rational but also visually appealing.
2. Innovative Operating Mechanism: This mechanism, crafted exclusively for this advanced vacuum circuit breaker, aligns perfectly with the vacuum interrupter's characteristics. It ensures superior reliability and longevity with maintenance-free operation, serving as a benchmark for operational excellence.
3. Flexible Handcart Design: The inclusion of a screw-rod push mechanism facilitates effortless panel insertion or withdrawal. Moreover, it includes a forced mechanical interlock system to implement the "Five Prevention" functions, making it adept for various operational contexts, even under challenging conditions.
