<p>PURPOSE:To accurately and automatically detect abnormality in an insulator- washing device so as to notify a control station of the abnormality by storing a secular change in each of flow signal into a flowmeter joined to the primary side a pump or to the secondary side thereof, and then connecting an arithmetic processing device which finds an abnormal flow change to the flowmeter. CONSTITUTION:A flowmeter 14 is joined to the secondary side of the main valve 5 of a pump 2 to detect a flow signal on the amount of water flowing through this secondary-side part during operation of an insulator-cleaning device. The flow signal extracted from the flowmeter 14 is then inputted into an arithmetic processing device 15 attached to a control board 10. This arithmetic processing device 15 stores a secular change in each of flow signal extracted from the flowmeter 14 while enclosing a program for finding an abnormal flow change and automatically transmitting a signal indicating abnormality, given out when the abnormality is acknowledged, to a control station to make a request for repair and inspection of the device. Thus, abnormality can surely be detected to automatically notify the control station of the abnormality.</p> |
