A fan monitoring method for a frame circuit breaker. A fan is used for heat dissipation of the frame circuit breaker. The fan monitoring method comprises: collecting a real-time temperature of a frame circuit breaker; looking up a temperature and rotational speed comparison table according to the real-time temperature and determining rotational speed data corresponding to the real-time temperature; generating a driving signal according to the rotational speed data, and the driving signal driving a fan to rotate; collecting a real-time rotational speed of the fan and generating a feedback signal; and based on the real-time temperature, the rotational speed data and the feedback signal, determining the working state of the fan. Also disclosed is a fan monitoring apparatus for a frame circuit breaker, which executes the monitoring method. In the present invention, the temperature, driving rotational speed and actual rotational speed of a frame circuit breaker are comprehensively considered, which solves the problem of fan reliability when the frame circuit breaker uses a fan to perform forcible heat dissipation.
Description
technical field [0001] The invention relates to the field of low-voltage electrical appliances, more specifically, to the heat dissipation technology of frame circuit breakers. Background technique [0002] The temperature rise of the frame circuit breaker during operation directly affects the performance of the material, and further affects the performance indicators of the product and the reliability of the product. Improving the temperature rise of the circuit breaker and improving its heat dissipation conditions can effectively improve the quality and performance of the product. Fan forced cooling is widely used in other industry products. For example, the Chinese patent application with publication number CN101466245A discloses a fan cooling device and a fan speed control method, including a temperature sensor, a temperature monitoring unit, a processing unit, a driving unit, and a fan. The temperature monitoring unit is used for comparing the sensing result of the te...
