High-voltage switch contact measuring temperature system based on wireless frequency-hopping communication technology

摘要

The article is based on wireless frequency-hopping communication technology, high-voltage bus switch contacts and temperature monitoring, combined with the main electric connection, the location of the measured points, name and temperature values are displayed on a computer screen at the monitoring center. ECS in the introduction of the loop current value, calculated temperature rise, given the ambient temperature, according to the measured temperature to determine whether the temperature of switch contacts and high voltage bus exceeds the temperature limits. beyond the set temperature value will automatically be timely warning, and provide temperature data measured point characteristic curve for the power plant managers a convenient method of analyzing data to early prevention of accidents and ensure safe operation of power systems.
