Abstract
The utility model relates to a frequency conversion energy-saving control system of a dust removal draught fan. The frequency conversion energy-saving control system of the dust removal draught fan comprises a frequency converter. The frequency conversion energy-saving control system of the dust removal draught fan is characterized in that a power source (1) is connected with one end of a first vacuum circuit breaker (2), the other end of the first vacuum circuit breaker (2) is connected with an input end of the frequency converter (3), an output end of the frequency converter (3) is connected with one end of a second vacuum circuit breaker (4), and the other end of the second vacuum circuit breaker (4) is connected with a high-voltage synchronous motor (5). The frequency conversion energy-saving control system of the dust removal draught fan is provided with a power frequency bypass system which enables the power source (1) to be connected with one end of a third vacuum circuit breaker (6), and the other end of the third vacuum circuit breaker (6) is connected with the high-voltage synchronous motor (5). The frequency conversion energy-saving control system of the dust removal draught fan can change a motor speed to adjust a draught fan speed through the frequency converter, thereby achieving the purpose of saving energy. In addition, when the frequency converter breaks down, a drought fan system can be started in a power frequent mode. Starting or stopping of the drought fan system is achieved through a centralized control system of users or operation of the drought fan, and thereby the stable operation of production is guaranteed.
