Power System Temperature Monitoring

sensor for Power System Temperature Monitoring

Temperature is a very important parameter in industrial production, monitoring and control of temperature are required in many occasions. In the power system, the high-voltage transmission line is a fault high-incidence area. Due to the increase of the power load, the sudden event of the heating of the power equipment occurs frequently, which affects the output quality, production efficiency, safe and reliable operation of the power. Therefore, the automatic monitoring of temperature has become an important part of safe production in the power industry.

Many equipment accidents in the power system are initially caused by abnormal heating, and many substations with a large number of electrical equipment have implemented with unattended working conditions. If these equipment are under high load for a long time, the phenomenon of temperature rise often occurs. In the early stage of heating, the naked eye is often unable to detect it. When the temperature increases cumulatively, thermal failure will eventually occur.

At present, non-contact infrared temperature measurement technology is the most effective detection tool in the field of preventive maintenance of power systems, which can quickly and accurately detect whether there is an abnormal temperature problem in power distribution equipment.

Using infrared thermopile sensors to monitor the temperature of operating electrical equipment, it is possible to directly observe whether there is a suspected fault in the equipment. By combining with the Internet of Things, cloud computing and other technologies, the monitored equipment temperature and other abnormal events in the form of digital signals.It can effectively help power workers solve thermal faults and defects in the operation of substation equipment, and ensure the safe and stable operation of electrical equipment.

Thermopile Sensor MRTD-3011

MRTD-3011 is a non-contact type digital thermopile sensor with I2C output. The thermopile chip is based on MEMS technology, consists of hundreds of thermocouples connected in series. Using Seebeck principle, when there is a temperature difference between the target and the environment, the sensor gives the corresponding voltage output, therefore detecting the existence of the target or the temperature of the target. This sensor can be working in the temperature range of -20~85℃, and can measure during the range of -20~+250℃.

Can the Two Voltages of Mq-7 Exist All the Time, or Do They Need to Be Powered Alternately? if It is an Alternate Power Supply, What is the Appropriate Power Supply Time?

It requires alternate power supply. Please check the information on the product manual. This sensor is powered by 1.5V and 5V alternately. The low temperature and low voltage (1.5V) state can detect CO, and the high voltage (5V) is the desorption process. The recommended 5V voltage duration is 60s, 1.5V voltage duration is 90s to alternately supply power. Since it is a desorption process at 5V, it is normal for the voltage to drop when CO is 150ppm.

What is the Difference Between Semiconductor Sensors and Electrochemical Sensors?

There is no good linear correspondence between the gas concentration and voltage of the semiconductor sensor, and it is generally only used for fixed-point calibration products; there is a good linear correspondence between the gas concentration and the output current of the electrochemical sensor, and can be made into quantitative detection products.

What Are the Precautions for Manual Soldering of Semiconductor Sensors?

1. Flux: rosin flux with the least chlorine; 2. Constant temperature soldering iron; 3. Temperature: 250℃; 4. Time: no more than 3 seconds.
