Product Overview

High‑voltage cable cross‑bonding grounding boxes are mostly buried underground or deployed outdoors, bringing difficulties for manual inspection and delayed hazard identification. Abnormal sheath circulating current, excessive induced voltage, over‑heated joints and water accumulation inside boxes will accelerate cable insulation ageing, and may trigger severe accidents including sheath breakdown, cable fire and line outage.

The Haosheng intelligent grounding‑box monitoring device is an integrated industrial monitoring terminal specially developed for underground‑cable grounding boxes. It integrates acquisition units for 3‑channel circulating current, 3‑channel induced voltage, 3‑channel temperature and 1‑channel water‑immersion detection, enabling 24‑hour uninterrupted synchronous collection of full‑dimension operating data of grounding boxes. Equipped with dual‑mode RS485 and WIFI by default, with 4G available for custom configuration. Adopting standard industrial communication protocols, it can seamlessly connect with third‑party industrial‑control systems and power‑monitoring platforms without locking to proprietary backend systems. Parameter‑over‑limit status is uploaded in real‑time via communication interfaces. It replaces manual on‑foot inspection and realizes all‑weather monitoring and early‑warning for cable grounding‑sheath conditions.

Featuring IP68 fully‑sealed waterproof design, the device runs stably under underground water accumulation and rain immersion scenarios. It is suitable for batch‑renovation deployment of underground cable tunnels, suburban cable lines and tunnel‑cable grounding boxes.

Core Product Advantages

1. Integrated Synchronous Acquisition of Four Parameters
   Simultaneously monitors four core parameters: grounding circulating current, sheath induced voltage, box temperature and internal water accumulation. It covers all potential safety hazards of grounding boxes. Multi‑dimensional monitoring can be completed by one single device without stacking multiple sensors, effectively reducing overall project cost and construction complexity.
   
2. High‑precision Acquisition with Strong Anti‑interference Performance
   Circulating‑current measuring range: 0~100 A, accuracy ±0.05 A; induced‑voltage measuring range: 0~100 V, accuracy ±0.5 V; temperature‑measuring range: ‑50℃~+200℃, error ≤1℃. Equipped with self‑developed filtering algorithm, it effectively suppresses power‑frequency electromagnetic interference from cables. Measurement data remains stable without jumping, meeting industrial‑grade monitoring accuracy requirements.
   
3. IP68 Fully‑sealed Protection with Dual Industrial Certifications
   Adopting integrated potting housing with IP68 ingress‑protection rating, it can operate under long‑term water immersion. Passing both EMC electromagnetic‑compatibility and neutral salt‑spray certifications, it works stably in harsh environments such as underground humidity, acid‑alkaline soil and high‑EMI cable tunnels with strong environmental adaptability.
   
4. Standardized Communication Protocols for Flexible Third‑party‑system Integration
   Dual‑mode RS485 and WIFI are standard; 4G is optional upon request. The RS485 interface complies with Modbus‑RTU industrial protocol and can directly connect to power industrial‑control systems such as PLC and SCADA. WIFI supports universal IoT protocols including MQTT for flexible integration with diverse third‑party monitoring platforms and data middle‑platforms, delivering flexible networking for different project architectures.
   
5. Convenient Deployment and Low O&M Cost
   Two power‑supply solutions are available: wide‑range DC power supply and built‑in lithium‑battery power supply. The battery‑powered version requires no external mains power or cabling. Installation can be finished by opening the grounding‑box cover without modifying original grounding structures. The compact integrated body fits internal space of various standard grounding boxes. Snap‑in mounting enables plug‑and‑play, and ordinary maintenance staff can complete rapid deployment. Local configuration software supports modification of alarm thresholds and data‑reporting cycles for easy commissioning and maintenance.
   
6. Full‑dimensional Customization for Diversified Project Requirements
   Full‑range ODM/OEM services are supported. Customizable items include measuring range, alarm threshold, communication protocols, housing appearance, silk‑screen LOGO and neutral packaging. Secondary software‑hardware development is supported for seamless docking with various third‑party power systems and platforms. Both small‑batch and mass‑volume orders are acceptable to satisfy differentiated requirements for various scenarios.
