(Summary description)
(1) High-voltage vacuum circuit breaker operation detection 2 Manually perform the open circuit operation several times, the disconnection state is correct, and the counter is operating well.
(2) The main contact confirms the spring state. Remove dust and old grease, and then apply new grease thinly and evenly.
(3) The external fasteners are tightened overall. Clean the suppressed insulating materials and insulators.
(4) Whether the connection of the control circuit wires of the operating mechanism and the control parts is tight. Whether the connection of the bolt and the nut is loose. Check whether the connection between the shaft and the lock becomes dry. Then add a small amount of engine oil.
(5) Check whether the visible auxiliary switch is in good motion and contact. If abnormal, find out the cause, repair or replace it.
(6) Measurement of insulation resistance: The reference value of insulation resistance of the main contact part to the ground is above 500MΩ.
