40.5kV Outdoor High Voltage Sulfur Hexafluoride Circuit Breaker

Timetric 40.5kV Outdoor High Voltage Sulfur Hexafluoride Circuit Breaker  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.

Timetric  40.5kV Outdoor High Voltage Sulfur Hexafluoride Circuit Breaker Feature And Application

The outdoor high-voltage vacuum circuit breaker is primarily utilized in AC 50Hz, 40.5kV power grids to handle load current, no-load current, and short-circuit current. It is suitable for use in rural power grids and small power systems, offering an oil-free replacement solution for urban and rural networks.

The circuit breaker's vacuum arc extinguishing chamber is designed with a ceramic shell and a cup-shaped longitudinal magnetic field contact structure. It utilizes copper chrome contact material, ensuring excellent performance in breaking and closing short-circuit currents. Moreover, the circuit breaker is characterized by its compact size, lightweight construction, and aesthetically pleasing appearance.

The vacuum arc extinguishing chamber and insulation support sleeve are designed to be compact, while the outgoing conductor rod is protected by a layer of silicone rubber. These design features enable the circuit breaker to withstand challenging weather conditions and operate reliably in dirty environments.
