Problems solved by technology
Due to the requirements of the maintenance process, the staff must disassemble and overhaul the moving contact. According to the power system maintenance records, because the GW16 type disconnector rotating contact is inserted into the conductive arm, it is difficult to disassemble after long-term operation, and maintenance personnel use brute force to cause equipment damage. The possibility of damage to the contact surface of the moving contact. In addition, the damage to the thread of the moving contact causes the contact with the conductive arm to be loose, and there is a hidden danger of heating of the equipment joint. In order to solve this problem, a safe, reliable, practical and flexible professional maintenance moving contact is urgently needed. head disassembly tool

The invention relates to a disassembling and overhauling tool for equipment in a transformer substation, in particular to a sleeve wrench special for disconnecting switch moving contact overhaul. The sleeve wrench special for the disconnecting switch moving contact overhaul comprises a fixing seat (1), a fixing seat handle (10) is arranged on one side of the fixing seat (1), a plastic clamping sleeve (4) is tightly attached in the fixing seat (1), a press plate (6) is arranged on the plastic clamping sleeve (4), the plastic clamping sleeve (4) is fixed in the fixing seat (1) through an embedded base disc (7) on the bottom of the fixing seat (1), and a torque wrench dedicated fixing disc (8) is arranged on the bottom of the embedded bottom disc (7). The sleeve wrench special for the disconnecting switch moving contact overhaul can fully solve the problems that a GW16 type disconnecting switch moving contact is inconvenient to disassemble and the like, overhaul personnel can be prevented from using brute force to damage the surface and the threads of the moving contact, safe reliability of working of the personnel can be improved, working intensity can be lowered, working time can be saved, and efficiency can be improved.
Description
technical field [0001] The invention relates to a tool for dismantling and repairing equipment in a substation, in particular to a special sleeve for checking and repairing a moving contact of a disconnector. Background technique [0002] During the normal operation of the isolating switch of the 220kV substation, the staff needs to regularly check and maintain the equipment. Among them, the moving contact of the GW16 type disconnector is rotated and tightened in the upper conductive arm, which fully ensures the good contact between the moving contact and the conductive rod. Due to the requirements of the maintenance process, the staff must disassemble and overhaul the moving contact. According to the power system maintenance records, because the GW16 type disconnector rotating contact is inserted into the conductive arm, it is difficult to disassemble after long-term operation, and maintenance personnel use brute force to cause equipment damage. The possibility of damage t...
