We are now living in a social environment based on information technology. There are mainly three types of information technology in our society, one is information collection, the other is information transmission, and the last one is information technology. The last one is the processing of information. The wireless temperature sensor is a device for information transportation and processing. What are the characteristics of this wireless temperature sensor device in design?
In the industrial and power industries, the normal operation of electrical equipment ensures the normal operation of the society and the normal life of the people, so the reliability of the equipment is very important. Many companies advocate preventive maintenance of equipment, and temperature is the most important monitoring parameter in preventive maintenance. Too high or too low temperature means the possibility of failure. Realizing temperature online monitoring is an important means to ensure the safe operation of high-voltage equipment.
High temperature overheating directly leads to a decrease in the mechanical strength and physical properties of electrical materials, and an increase in the contact resistance value. In the continuous flow state, the oxidation of the connection point of the equipment will be accelerated. The oxidation result will cause the contact resistance value to continue to increase. High temperature overheating. And the problem of high temperature overheating is a continuous development process. If it is not controlled, the degree of overheating will continue to intensify. The increased contact resistance value of each temperature change will increase the heat in the next cycle, and the increased temperature will make The working condition of the joint is further deteriorated, thus forming a vicious circle, which seriously affects the service life of the electrical equipment.
The traditional temperature measurement method has a long period, complicated construction, low efficiency, and inconvenient management. When a fault occurs, it takes a lot of manpower to check and re-lay cables. In certain occasions, the monitoring points are scattered, the environment is closed or there is high voltage, and many temperature measurement methods cannot achieve measurement work.
The wireless temperature monitoring and early warning system is a high-tech product integrating advanced sensing technology, digital identification technology, wireless communication technology, low power consumption technology, anti-interference technology and automatic control technology. It consists of a wireless temperature display instrument, a wireless temperature sensor, and a background management system.
It can realize on-site and remote simultaneous online monitoring and early warning of equipment temperature changes under various harsh environmental conditions, which is convenient for maintenance personnel to fully grasp the equipment operation status in a timely manner. It is specifically used in various contacts and connection points of electrical equipment, such as: busbar joints, cable joints, outdoor knife switch contacts, transformers and motor lead joints and other measuring points. The system can display the distribution of the entire temperature field in the form of an electronic map, and can clearly find abnormal temperature points and determine hidden troubles. Take measures in advance to avoid accidents.
At present, the wireless temperature sensors that have been publicly sold on the market are mainly used in our agricultural production scientific research or other fields such as home life. As long as this wireless temperature sensor product is used, in our daily life, we can save a lot of trouble, in the need of transportation information, the use of wireless temperature sensors can also help us achieve the effect we want as soon as possible.
