DGG Deeply Integrated Primary and Secondary Pole-Mounted Vacuum Circuit Breaker

Key Functions

Switching and Fault Interruption

The vacuum circuit breaker performs normal circuit opening and closing operations and can interrupt overload and short-circuit fault currents together with the protection system.

Electrical Measurement

Current and voltage information can be collected for feeder monitoring, protection and distribution network operation.

Protection

The integrated protection system can respond to abnormal operating conditions and provide protection logic for distribution feeders.

Fault Detection

Operating data can be used for feeder fault detection and support fault section identification and isolation.

Remote Monitoring

Breaker operating status and electrical information can be monitored through the matched intelligent controller and distribution automation system.

Remote Control

The circuit breaker can support remote opening and closing operations when configured with the appropriate controller and communication interface.

Automatic Reclosing

According to the protection and control configuration, automatic reclosing can be implemented to support feeder fault handling and power restoration.

Key Features

Primary and Secondary Integration
Combines primary switching equipment with secondary measurement, protection, monitoring and communication functions.

Designed for Distribution Automation
Suitable for feeder automation and smart distribution network applications.

Vacuum Interruption Technology
Uses vacuum interruption for circuit switching and fault current interruption.

Integrated Three-Phase Structure
Compact three-phase configuration helps simplify pole-mounted equipment arrangement.

Remote Operation Capability
Can work with an intelligent controller for remote opening, closing and system monitoring.

Fault Detection Support
Provides operating information required for feeder fault identification and isolation.

Automatic Reclosing Capability
Supports automatic reclosing according to the selected protection and control scheme.

Project-Based Configuration
Measurement, protection, controller and communication functions can be configured according to utility or EPC project requirements.

During normal operation, the pole-mounted vacuum circuit breaker controls the connection and disconnection of the distribution feeder.

When abnormal current or a system fault is detected, the secondary protection and control system processes the corresponding electrical signals and issues a trip command according to the configured protection logic. The operating mechanism drives the vacuum interrupter to open the circuit and isolate the fault.

After the fault condition is evaluated, the controller can perform reclosing operations according to the preset protection strategy. With communication capability, operating data and breaker status can also be transmitted to the distribution automation system for remote supervision and control.

The vacuum interrupter extinguishes the arc in a vacuum environment, enabling the breaker to interrupt current and restore dielectric strength after current interruption.
