Professional intelligent monitoring device for box type transformers, manufacturer of environmental management systems for box type substations, customized intelligent integrated monitoring project solutions for power equipment, switchgear, ring main unit, substations, distribution stations, and switching stations.

Introduction to environmental management system products for box type substations

Cabinets such as box type substations and containerized box type substations are outdoor electrical equipment that operate in extremely harsh environments (such as large temperature differences in the morning and evening, large foundation moisture regain, high relative humidity in the air, high temperatures in summer, etc.). A large number of cabinets operating on site have experienced varying degrees of condensation or icing inside. The water droplets generated by condensation fall on the internal components, wiring terminals, busbars, etc. of the cabinet, forming insulation defects and accidents, endangering equipment and personal safety.
The environmental management system of the box type substation adopts comprehensive treatment and control measures for the formation mechanism of condensation or ice (relative humidity of air, temperature of air inside the box, etc.), completely destroying the conditions for condensation or ice formation, and eliminating cabinet condensation or ice.

The specialized environmental management system for box type substations can measure multiple environmental temperatures and humidity, multiple dew point data, multiple smoke alarms, and oil surface temperature data inside the box.
