POLE-MOUNTED SWITCH

Digital Deeply Integrated Vacuum Circuit Breaker (VCB)

Standard: IEC 62271-100:2008

The digitally deeply integrated pole-mounted VCB builds upon electronic sensing and on-site digitization by incorporating ceramic capacitor power acquisition. This eliminates the risk of electromagnetic transformer ferromagnetic resonance, achieves higher integration, and enables faster energized installation, ultimately enhancing power supply reliability.

Features

Enhanced Safety: Deep integration of primary and secondary equipment reduces auxiliary components and failure risks; interlocking prevents mis-remote control due to automation.

Effective Protection: Enables selective tripping for short-circuit faults (multi-level precise grading coordination) and selective automatic isolation for single-phase ground faults (transient method fault location).

Advanced Technology: Features built-in ECT and EVT; utilizes capacitor power acquisition for terminal power supply; achieves IP67 protection level; whole machine partial discharge is no more than 20pC.

Intelligent Operation: The terminal uses machine learning and original algorithms to autonomously analyze and act upon short-circuit or single-phase ground faults.

User-Friendly Design: Simple to use, requires no changes to operating habits, additional tools, or specialized training; factory-commissioned with modular, hot-swappable maintenance, reducing reliance on specialized technicians.

Compact Miniaturization: Deep integration of primary and secondary components (built-in ECT, EVT) reduces weight by over 20kg, simplifying on-site construction and improving installation efficiency.
