Monitor and Control Device (Integrated Fault Isolation Device)

The integrated fault isolation device is an intelligent monitoring unit combining a vacuum interrupter chamber, operating mechanism, 10kV line high-voltage energy-taking power supply, smart control terminal, and current/voltage sensors. This integrated design enables online monitoring of power distribution lines, utilizing mobile GPRS/APN or 4G/APN private networks to upload data to a management system. It provides functions for monitoring, metering, protection, fault location, and isolation on distribution lines.

Features

Integrated Design: Combines vacuum interrupter, mechanism, 10kV power supply, sensors, and smart terminal, eliminating additional on-site wiring. Lightweight design under 130kg with operational power consumption less than 3W.

Electromagnetic Compatibility: The intelligent control terminal ensures reliable data acquisition, processing, and transmission without interference.

Backup Power Supply: Provides a backup power source for at least 120 hours during line outages or supports over 30 consecutive circuit breaker open/close operations.

Anti-Open-Circuit Design: Allows for direct live replacement of secondary terminals after the device is commissioned on the line.

Low Operating Voltage: Normal operation starts at 4.5kV (phase voltage), with primary side capacitance current less than 10mA at the line's rated voltage.
