Product Introduction
In power distribution facilities, the disconnection contact points and cable joints of various equipment may experience increased contact resistance due to poor contact, looseness, insulation aging, arc impact, and other reasons during long-term operation, resulting in a continuous increase in contact point temperature and affecting the safe and stable operation of the power system. Therefore, real-time monitoring of temperature at key points of power distribution facilities is increasingly recognized and valued by everyone.
The YX wireless temperature measurement system independently developed by the company adopts micro electromechanical technology and Internet of Things technology, which is a new concept of intelligent wireless temperature measurement system. Suitable for temperature monitoring of electrical contacts, busbars, cables, and other electrical contacts of high and low voltage equipment such as high and low voltage switchgear, transformers, etc. in industries such as power, steel, mining, and petrochemicals.
