になってきている。(Prior Art) Most substations that are affected by salt wind from the sea are equipped with an insulator cleaning device to keep the insulation of exposed insulators high.
Insulators are cleaned with hot water on a regular basis or before the salt content reaches the allowable limit. Until now, the operation and maintenance of such an insulator cleaning device have been mostly performed by the staff working in the substation. However, recently, many devices in the substation have become remotely controllable,
There is a widespread labor saving in which the operation of all the equipment in a substation is centrally monitored and controlled at a remote control station so that the substation is always unattended. For this reason, the insulator cleaning device also responds to such unmanned operation by automating the measurement of the amount of salt adhering to the insulator, the selection of a cleaning method program according to the wind conditions, etc. You can drive on command.

信号を制御所に送って故障発生を知らせるようになって
いる。Therefore, recently, the insulator cleaning device is also equipped with an abnormality detection function for automatically determining whether or not the operation is normally performed. The conventional monitoring items for this purpose are the discharge pressure of the pump, the current value of the pump drive motor, the specific resistance value of the wash water, the residual water level in the water storage tank, the progress of the sequence of the control panel, etc. As soon as any of the items deviates from the standard value, the device is stopped and an alarm signal is sent to the control station to notify the occurrence of a failure.

であるという問題がある。However, if the strainer provided in the middle of the water supply line is clogged and water discharge from the nozzle is blocked, or if some of the pipe line is damaged and there is significant water leakage, the discharge pressure of the pump, Although the current values of the pump drive motor change somewhat, the allowable values for these values are set to have a large width that allows for differences depending on the size of the cleaning section (insulator installation section to be cleaned). Therefore, it may be difficult to find the abnormality. In particular, the spiral pump used in the insulator cleaning device has the characteristics that the discharge pressure of the pump and the current value of the pump drive motor do not change significantly even if the flow rate changes. There is a problem that it is difficult.

Since 4) was attached to detect the flow rate signal,
When a strainer (7) provided in the middle of the water supply pipe (3) is blocked and water discharge from the nozzle (8) is blocked, or a part of the water supply pipe (3) is damaged to cause water leakage. Even in such a case, these abnormalities can be reliably grasped as changes in the flow rate. Then, the arithmetic processing unit (15) connected to the flow meter (14) compares it with a standard flow rate stored in advance, and when a difference of a set value or more occurs, it outputs an abnormal signal. However, even if the flow rate signal indicates an abnormality, if the other monitoring items are normal, it is not necessary to stop the device immediately because it is an abnormality in the initial stage. In particular, the clogging and water leakage of the strainer (7) change gradually over a long period of time, so that the arithmetic processing unit (15) does not make an instantaneous judgment, but changes the flow signal over time. By memorizing such changes, it is self-diagnosed whether the changes are normal or not. When an abnormal flow rate change is recognized, the arithmetic processing unit (15) automatically sends a signal to that effect to the control station to request repair and inspection.

The result of self-diagnosis by the arithmetic processing unit (15) can be automatically notified to the control station. Therefore, it becomes possible to detect an abnormality of the insulator cleaning device installed in the unattended substation earlier and more reliably than before.
