The circuit breaker in the low-voltage cabinet circuit is prone to wear and tear of dynamic and static contacts, loosening of fasteners on the terminal busbar, and other phenomena due to long-term operation and use. If not detected and maintained in a timely manner, it will generate high temperatures, cause aging of insulation components, fire, or lead to circuit breaker burning. In order to reduce faults caused by excessive heating during the use of circuit breakers, it is necessary to install NTC temperature sensors on the circuit breaker to monitor the temperature at all times.
The circuit breaker system is equipped with a built-in NTC temperature sensor, which measures the ambient temperature through the temperature sensor and processes it to the MCU unit to determine the temperature. When the temperature rises or exceeds the set value, the circuit breaker status is remotely controlled through the relay output unit; In addition, the position and status of the circuit breaker can be displayed on the display unit through the input signal processing unit, and the system achieves information transmission with the intelligent controller or integrated monitoring system of the circuit breaker through the communication unit. It is equipped with an NTC temperature sensor to monitor and control the temperature of the circuit breaker, facilitating maintenance of the distribution cabinet by staff, avoiding faults caused by high circuit breaker temperatures, reducing losses caused by high circuit breaker temperatures, and improving the maintenance and service life of the product.
A ground ring NTC temperature sensor, which is packaged with high-precision single ended glass sealed thermistors, has high accuracy, high waterproofing, and can be used in harsh environments such as high temperature and humidity; It utilizes a metal casing design to achieve more accurate temperature measurement, high sensitivity, and better reliability; It is assembled with high thermal conductivity wires and has good stability, making it suitable for temperature measurement of circuit breakers.
