Abstract
Description
technical field
[0001] The invention relates to the technical field of laser cleaning, in particular to a laser cleaning system used for the opening and closing of a switch of a substation. Background technique
[0002] During the operation of the substation knife switch, due to the overcurrent thermal effect of the substation knife switch, when the contact resistance of the contact is too large, it is prone to overheating, the static contact of the knife switch isolating switch is jammed, and the opening and closing are not in place. It also happens from time to time; the reason is that the moving and static contacts of the switch knife and the internal transmission accessories are seriously accumulated. The current method to deal with such problems is to cut off the power of the equipment and manually clean the contact surface to reduce the amount of dust on the surface, thereby reducing the contact resistance. This processing method has the following disadvantages: first...
