SW-600H, SW600CTH ring-type wireless temperature measurement transmitter module [Copy link]

I. Overview

The SW-600H ring-type wireless temperature measurement system adopts a passive power-taking design. The temperature measurement component of the device is installed near the connection point where the current-carrying conductor of the high-voltage switch is prone to temperature rise. The temperature sensor signal installed at the high-potential end can be isolated and transmitted to the instrument at the low-potential end through wireless data transmission. For removable switchgear, it is only necessary to install the sensor module on the trolley side, which is very convenient for installation, modification and maintenance. The display instrument of the device is also equipped with an internal temperature sensor of the cabinet, which can display the relative temperature rise of the hot spot. The application of this device provides an effective monitoring means to solve the 11.7 "Prevention of overheating of the current-carrying circuit of the switchgear" in the "Eighteen Major Power Grid Accident Measures of the State Grid Corporation".
