XMT-22B digital temperature display regulator has the advantages of high resolution, large range, easy reading, etc. It is suitable for many industrial scenarios.
The application scenarios of XMT-22B digital temperature display regulator in power system mainly include the following aspects:
1. Power Transformer Temperature Monitoring
XMT-22B is commonly used for monitoring the winding and oil surface temperature of power transformers. It can be mated with BWR, BWY series transformer winding and oil surface thermometers to realize telemetry and telecommunication of power transformer winding and oil surface temperature. By accurately measuring and displaying the temperature, XMT-22B can help the operation and maintenance personnel to understand the operation status of the transformer in real time, and discover the overheating and other abnormal conditions in time, so as to ensure the safe operation of the transformer.
2. Cooling system control
During power transformer operation, when the temperature exceeds the set value, the XMT-22B can output a signal to activate the cooling system, such as a fan or oil pump, to reduce the transformer temperature. This automatic control function helps to extend the service life of the transformer while improving the operational efficiency of the system.
3. Remote monitoring and data transmission
XMT-22B can output standard 4-20mA current signals or 0-5V voltage signals, which can be connected to computers or other monitoring systems to realize remote monitoring and data acquisition. For example, through the RS485 interface, XMT-22B can transmit temperature data directly to the control room of the substation, which is convenient for centralized management and analysis by operation and maintenance personnel.
4. Alarm function
XMT-22B is equipped with two sets of upper and lower limit alarm functions, which will output an alarm signal when the temperature exceeds the set alarm value. This function can remind operation and maintenance personnel to take measures in time when the temperature rises abnormally to avoid equipment damage.
5. micro-management
XMT-22B supports connection with computer system to realize microcomputerized management. In this way, the operation and maintenance personnel of the power system can manage the equipment more efficiently and realize intelligent monitoring and data analysis.
6. Suitable for a wide range of environments
The XMT-22B is able to operate normally over a wide range of ambient temperature (-20~+55°C) and relative humidity (<95%), which makes it suitable for a wide range of complex operating environments in power systems, including outdoor substations and indoor distribution rooms.
summarize
XMT-22B digital temperature display regulator is mainly used in power system for transformer temperature monitoring, cooling system control, remote monitoring and data transmission, alarm function and microcomputerized management. It helps to safeguard the safe operation of power equipment and improve the reliability and operational efficiency of the power system by accurately measuring and controlling the temperature.
