Deep Primary And Secondary Fusion Double-Side Power Supply Column Circuit Breaker

1. Product structure and configuration
Integrated current sensor:
Installed on the outgoing side, used to monitor the line current in real time.

Voltage sensor:
Installed on the incoming and outgoing sides, used to monitor the line voltage.

Dual power supply:
The power module is installed on both sides of phase A and phase C to ensure power supply reliability.

Sensor compensation adjustment box:
Each phase is equipped with a phase current sensor, a zero-sequence current sensor and a phase voltage sensor, and the signal is transmitted to the compensation adjustment box through a shielded cable.

The output signals include: phase current, zero-sequence current, phase voltage and zero-sequence voltage signals.

2. Core functions
Capacitor power supply system:
It consists of a primary unit and a power module, which can provide energy to the controller when the controller backup power supply is cut off, and realize the closing and opening operations of the circuit breaker.

Ensure reliable operation in emergency situations and improve system safety.

Deep primary and secondary integration:
The primary equipment (circuit breaker) and secondary equipment (sensor, controller) are deeply integrated to realize the intelligentization of data acquisition, transmission and control.

Support real-time monitoring and remote operation of distribution automation system.

3. Technical features
High-precision sensor:
Each phase is equipped with independent current and voltage sensors to ensure the accuracy and real-time performance of data collection.
Zero-sequence current and zero-sequence voltage sensors support ground fault detection and protection.

Dual power supply design:
Phase A and phase C are powered by dual power supplies to improve power supply reliability and avoid system failure caused by single point failure.

Shielded cable transmission:
Sensor signals are transmitted through shielded cables with strong anti-interference ability to ensure the stability of signal transmission.

Capacitor power backup:
When the controller power fails, the capacitor power module can still provide operating energy for the circuit breaker to ensure uninterrupted operation of the system.

4. Application scenarios
