Power Quality Monitoring Device

The PQ-F335DT power quality monitoring device features a compact, fully enclosed design specifically tailored for photovoltaic grid‑connected switchgear, offering both energy‑metering and historical data‑query capabilities. Equipped with a 5.6‑inch color LCD, it provides graphical visualization of power quality parameters. Running on the Linux operating system and compliant with the eight national standards for power quality, it achieves Class A measurement accuracy. The unit incorporates a built-in 16‑bit, six‑channel synchronous A/D converter, integrating steady‑state and transient monitoring, high‑precision measurement, large‑capacity data storage, GPS time synchronization, and COMTRADE waveform recording in a single solution. The front panel includes four LED indicators for status monitoring, configuration, and parameter adjustment. It can be flexibly configured to suit a variety of application scenarios.

SF6 Gas Leakage Online Monitoring System

The SF6 gas leak online monitoring system employs cutting-edge monitoring technologies to provide real-time, quantitative measurements of indoor SF6 concentration, O2 levels, and ambient temperature and humidity. It also features voice prompts when a person approaches, coordinated control of ventilation equipment, and multiple alarm output modes.

Intelligent Control Device for Switchgear / Wireless Temperature Measurement System

A next‑generation intelligent control device for switchgear, suitable for 6–35 kV indoor switchgear, including center‑mounted cabinets, handcart cabinets, fixed cabinets, ring main units, and other types. It features a dynamic primary‑circuit simulation diagram, high‑voltage live‑status indication, automatic heating and dehumidification with digital display and control, circuit‑breaker open/close status indication, energy‑storage status indication, earthing‑switch status indication, trolley position indication, integrity monitoring of the closing/opening circuits, human‑body‑induced live‑wire warning, in‑cabinet lighting, as well as wireless temperature measurement and voice‑based error‑prevention prompts. Additionally, it is equipped with an RS‑485 communication interface, enabling further advancement toward intelligent, networked, and digitalized switchgear operation.
