Analysis and corresponding processing method of abnormal operation of high voltage capacitors (4)
Aug 02, 2018

If the capacitor circuit connection (dot) connection is loose (poor contact) or disconnected or disconnected, it may cause high-frequency oscillating arc, causing the contact (point) to overheat and discolor. If it is not found in time, it may cause overheating and field strength of the capacitor. Too high and damaged. Countermeasures are as follows:


(1) Observe the change in color (ie, temperature change) of the wax cloth (the capacitor is pasted at 2/3) pasted between the capacitor case and the capacitor circuit connection (dot).


(2) Check the connection parts of the capacitor circuit (dot) for each maintenance to ensure good contact and no looseness or falling off of the leads.
