Wireless temperature sensor
In the industry and power industry, 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 enterprises 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. On-line temperature monitoring is an important means to ensure the safe operation of high-voltage equipment.
High temperature overheating directly leads to the decline of mechanical strength and physical properties of electrical materials, and the increase of contact resistance value. In the continuous flow state, the oxidation of the connection point of the equipment will be accelerated. The oxidation result will further increase the contact resistance value, increase the heat generation, and the temperature will continue to rise. lead to high temperature overheating. 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 contact resistance value increased by each temperature change will increase the heat of the next cycle, and the increased temperature will make it The working condition of the joint further deteriorates, thereby forming a vicious circle and seriously affecting the service life of electrical equipment.
The traditional temperature measurement method has a long period, complex construction, low efficiency, and is not easy to manage. When a fault occurs, it takes a lot of manpower to physically check and re-lay cables. However, in certain occasions, the monitoring points are scattered, the environment is closed or there is high voltage, and many temperature measurement methods cannot realize the measurement work.
The wireless temperature monitoring and early warning system (NT1000) 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 is composed of sensors and background management system. It can realize on-site, remote and simultaneous online monitoring and early warning of equipment temperature changes under various harsh environmental conditions, so that maintenance personnel can fully and timely grasp the equipment operating status. Specifically used in various contacts and connection points of electrical equipment, such as: bus joints, cable joints, outdoor knife switch contacts, transformers and motor lead wire 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 temperature abnormal points and determine potential failures. Take measures in advance to avoid accidents.
