If the misuse or close with load isolation switch occur, you should calmly to another in the opposite direction to avoid misuse may occur. Is this: It has been found with a load isolation switch misuse closing price after the vacuum can not be immediately opened again; when found with load brake, Ruoyi opened, may no longer fit (if opened a little, I found there are sparks, it can Now closed). Running an isolation switch should conduct inspections. In the manned substation should once per shift; in unattended Power Distribution least once a week. Junction isolation switch connector plate for overheating, discoloration, indicating poor contact, contact resistance, repair should open a connection point, the contact surface of the flat file and then sandpapering (but the switch connector plate zinc plated not removed), then Tighten the screws and use a spring lock washer. Moving contacts exist beside hammer, screw rotatably fixed contact isolation switch, or slightly move the position of supporting insulator factory direct isolation switch to eliminate the next attack; three-phase different period, you can adjust the screws at both ends of the rod insulators , thereby changing its effective length to overcome. The contact pressure between the contacts can be achieved by adjusting the clamping spring, and the extent of the clamp can be used to check the feeler. Contact between the generally coated with Vaseline to reduce friction and extend the life of high-voltage isolation switch price, but also to prevent contact oxidation. When isolating switch is in the off position, the angle of contact between the opened or distance does not meet the requirements should be adjusted by rod insulators.
