Three-phase multifunction meter

The product is a multifunctional power meter featuring programmable measurement, display, digital communication, and electrical‑energy pulse output capabilities. It can perform electrical parameter measurement, energy calculation, data display, data acquisition, and data transmission, making it suitable for a wide range of applications, including substation automation, distribution automation, smart buildings, and internal enterprise energy measurement, management, and performance evaluation. With a measurement accuracy class of 0.5 or 1.0, it supports on‑site LED/LCD display and remote RS‑485 digital interface communication, utilizing the MODBUS‑RTU communication protocol.

Microcomputer-based comprehensive protection device

The microcomputer-based integrated protection and monitoring device is suitable for the protection and control of bay units at voltage levels up to 66 kV. It features comprehensive functions for protection, measurement, control, automatic transfer of incoming lines, and communication monitoring, providing a complete solution for the protection and control of substations, power plants, high‑ and low‑voltage distribution systems, and plant auxiliary power systems, thereby effectively ensuring the safe and stable operation of both high‑ and low‑voltage grids and plant auxiliary power networks. The device can be integrated with other protection and automation equipment via communication interfaces to form an automated system. All units can be mounted in cabinets for centralized installation or installed directly on high‑ and low‑voltage switchgear.

Smart Dehumidification Device

The intelligent dehumidification device employs semiconductor cooling to remove moisture. It actively draws humid air from a sealed enclosure into a dehumidification duct via a fan; the water vapor in the air is condensed into liquid upon passing through the semiconductor cooling module and then discharged from the cabinet through a drainage pipe, achieving excellent dehumidification performance. By reducing the moisture content of the air, both relative and absolute humidity are lowered simultaneously, with virtually no increase in temperature and no adverse effects caused by temperature differentials. This fundamentally prevents or minimizes the occurrence of failures and avoids accelerating the aging of internal components and the cabinet itself due to high temperatures. The intelligent dehumidification device transforms passive condensation prevention into active condensation management, offering…
