1、 Product Overview
In the power transmission system, high-voltage switchgear plays a crucial role as the core hub. The numerous contact points inside the cabinet can cause oxidation corrosion, bolt loosening, and increased contact resistance due to long-term use, leading to equipment overheating and even serious malfunctions. Therefore, it is necessary to implement online temperature monitoring. The wireless temperature detection device uses wireless transmission of temperature signals, and the sensor is installed on high-voltage equipment without electrical connection to the receiving device. Therefore, wireless temperature measurement can solve the problem of difficulty in real-time online detection of contact temperature of high-voltage equipment. Has extremely high reliability and safety.
Our company's wireless temperature measurement device for switchgear is specifically designed for online temperature detection of high-voltage equipment. Using the 2.4GHz public radio frequency band. The temperature receiving display unit adopts a large screen LCD display, with clear temperature display. Equipped with a standard RS485 interface, it can communicate with the upper computer.
1、 Main functions
Real time monitoring of the temperature of each contact and other monitoring points in the switchgear;
◆ Using wireless measurement, there is no wire connection between the temperature probe and the main controller, which has strong anti-interference ability;
A host comes standard with 6 sensors and can connect up to 45 sensors (optional);
2.4GHz exempt from applying for radio frequency band;
◆ Warning and alarm output function (passive contact);
