Integrated Fault Insolation Device

Product Introduction

The integrated fault isolation device includes integrated pole-mounted circuit breaker, intelligent controller, analysis & management system, and various sensors. The product address the issue of distribution automation coverage of incremental equipment and mismatch of primary and secondary equipment in the large-scale construction and transformation of distribution network. At the same time, it realizes "four points" of line loss, continuously improves line loss management, and enhances operational efficiency and distribution reliability. The integrated pole-mounted circuit breaker is designed based on ZW32 vacuum circuit breaker, and the integrated sealed pole column integrates various advanced power equipment construction technologies, micro-power electronic sensing technologies, wireless communication technologies, online power extraction technologies, etc. The side and bottom operation windows make the operation more convenient.

Intelligent control unit with feeder terminal (TU) at the core has all the functions of feeder terminal unit (FTU). The upgraded extension function can receive fault sensor, temperature measurement, power quality and other information, make comprehensive analysis and judgment, and send fault pre-suspension alarm. Fault location information can be provided through single-phase grounding.

Product Features

1) Adopt integrated solid sealing pole design, integrating electronic voltage and current sensor and other sensors.

2) Advanced capacitive energy extraction technology, high energy extraction power, equipped with super capacitor and lithium battery dual backup power supply.

3) Use the Internet of Things and regional data analysis to achieve single-phase grounding point location. Single-phase grounding fault location is accurate.

4) Intelligent controller can access to intelligent terminal LTU and has edge computing function. It reserves the capability to access other equipments.

The integrated fault isolation device will definitely become the key equipment of intelligent distribution network and distribution IOT, and it will become the core technology of new generation distribution network together with intelligent terminal LTU and station area intelligent terminal.
