126kV Outdoor High Voltage SF6 Circuit Breaker

126kV Outdoor High Voltage SF6 Circuit Breaker  For Distribution  Introduction

The outdoor high voltage power distribution SF6 VCB is a compact and integrated unit comprising several essential components. These components include solid dielectric insulating rods, vacuum interrupters, current transformers, and voltage sensors. The VCB is equipped with either a permanent magnet drive or an electric motor drive for its operation.

The combination of these components creates a simplified and user-friendly unit that is both easy to operate and flexible in design. Each component works harmoniously with the others to ensure efficient performance. Notably, the control unit, although isolated from the rest, seamlessly integrates with the entire VCB system, acting as a single device.

In other words:

The SF6 VCB designed for outdoor high voltage power distribution is a compact unit that brings together various essential components. These components include solid dielectric insulating rods, vacuum interrupters, current transformers, and voltage sensors. The VCB can be operated using either a permanent magnet drive or an electric motor drive.

By combining these components, a simplified and adaptable unit is created, providing ease of operation and design flexibility. While the control unit remains isolated from the other components, it seamlessly integrates with the rest of the VCB, serving as a single, cohesive device.
