HZ-A52 Handcart-type Cable Fault Finder
Description
I. Introduction
The HZ-A52 trolley-type cable fault testing system is used for measuring the distance to various power cable faults. It highly integrates an independent cable fault location measurement, an integrated power frequency high-voltage power supply, a multi-pulse generator, and automatic discharge into a single trolley-type system. The system features a compact and safe high-voltage design with embedded distance measurement units and strong anti-interference capabilities.
II. Features
Integrated Three-Stage Capacitors: Perfectly suited for testing main insulation faults in power cables across multiple voltage levels.
Rapid Voltage Boost & High Power Output: Engineered to accelerate the testing process, significantly reducing onsite labor costs and downtime.
Intuitive HMI (Human-Machine Interface): The high-voltage power supply features a user-friendly interface with a simple, intuitive display for seamless operation.
25m Heavy-Duty Test Line: Facilitates flexible cable fault location in complex environments, covering both long and short-distance testing requirements.
Compliance with European Standards: Designed according to rigorous European safety standards, featuring professional-only authorization keys for secure access.
Real-time Grounding & Step Voltage Monitoring: Equipped with an advanced grounding circuit and step voltage protection to ensure maximum equipment and operator safety.
Emergency Stop & Automatic Discharge: Includes a dedicated emergency stop button and an automatic high-voltage discharge function to ensure safe shutdowns in any scenario.
Versatile High-Voltage Output Modes: Supports single and continuous pulse modes.
