The invention relates to a pressing and 
polishing device and in particular relates to a pressing and 
polishing device of a high-
voltage side extension line of a 
capacitor for 
electric power dynamic reactive compensation. Aiming at solving the technical problems, the invention provides the pressing and 
polishing device of the high-
voltage side extension line of the 
capacitor for the 
electric power dynamic reactive compensation, which has the advantages of complete 
extrusion, good polishing-flattening effect and high practicability. In order to solve the technical problems, the pressing and polishing device of the high-
voltage side extension line of the 
capacitor for the 
electric power dynamic reactive compensation, provided by the invention, comprises a second sliding rail, a second sliding block, a first connecting rod, a first rotary rod, a first bearing seat, a first 
bevel gear, a first inclined gear, a second bearing seat, a second inclined gear and the like; the first bearing seat is connected with the first rotary rod, and the middle part of the first rotary rod is in rotary connection with the first connecting rod; the lower end of the first rotary rod is connected with the first 
bevel gear. The pressing and polishing device has the effects of complete 
extrusion, good polishing effect and high practicability when pressing and polishing- flattening work of the high-voltage side extension line of the capacitor is carried out.
