Guangdong switchgear wireless temperature measurement

Many enterprises promote preventive maintenance of equipment, and the temperature is the most important preventive maintenance monitoring parameters, the temperature is too high or too low, means that the possibility of failures. Temperature monitoring is to ensure the realization of an important means of high voltage equipment for safe operation. A direct result of the high temperature thermal mechanical strength and physical properties of electrical material decreased to increase the contact resistance value, the continuing flow of state will be accelerated through the device connection point oxide, the result has prompted the contact resistance value continues to increase, the heat increased, the temperature continues to rise, the high-temperature overheating. The high temperature overheating problem is an evolving process, and if left unchecked, will continue to exacerbate the degree of overheating, each temperature change increases the contact resistance value, so that the heat will increase in the next cycle, the increase in temperature also allows working conditions further deteriorated joints, resulting in a vicious circle, seriously affect the life of electrical equipment. Conventional temperature measurement cycle is long, complicated construction, low efficiency, not easy to manage, to spend a lot of manpower and physical investigation of the event and re-laying of the cable fault. In certain situations under the monitoring point spread, enclosed environment, or high voltage, temperature measurement methods can not achieve a lot of measurements. Wireless temperature online monitoring system is a set of advanced sensor technology, digital identification technology, wireless communication technology, low-power technology, anti-jamming technology and automation and control technology of high-tech products, from wireless temperature display, wireless temperature sensor, background management system. Device temperature changes can under a variety of adverse environmental conditions achieve on-site, remote simultaneous online monitoring and early warning, and easy maintenance personnel fully grasp equipment operation. Specific applications in a variety of contacts, connection points of electrical equipment, such as: bus connectors, cable tie, outdoor knife switch contacts, transformer and motor lead joints measuring point. The system can display the entire temperature field distribution in electronic form of maps, outliers can be clearly found that the temperature determines the failure risks. Take measures in advance to avoid accidents.
