ELECTROSTATIC PRECIPITATOR OF DUST

摘要

PURPOSE:To previously prevent burning in a main body by automatically stopping the input to a high voltage generation part and a motor when the output current or output voltage of the high voltage generation part reaches the critical region current or the critical region voltage. CONSTITUTION:An output detection circuit 14 is constituted so that an abnormal signal is outputted when the output current of a high voltage power source 13 reaches the critical region current or when the output voltage of the power source 13 reaches the critical region voltage. Furthermore, the whole controlling circuit 15 stops the input to a motor 9 and the power source 13 when the abnormal signal is inputted. A maintenance sign means of the main body in an indication part announces that this abnormal signal is generated and maintenance of the main body 1 is made necessary. Furthermore a filter replacement sign means in the indication part indicates the replacement time of a dust collection filter. As a result, burning in the main body is previously prevented.
