It puts.
Background technology
Disconnecting switch is commonly called as disconnecting link, is the power equipment that dosage is larger in electric system, such as 10kv switch isolation switch,
Contact body structure is as shown in Fig. 4, and dynamic and static contact is incorporated into mode as horizontal plug-in type, and moving contact 13 operates machine in disconnecting link lower part
Structure controlled level screws in static contact 12, and compressing moving contact piece using static contact spring pressuring plate realizes current lead-through；It is dynamic and static after combined floodgate
Contact（Two conductive arms or connecting plate）Should keep point-blank, but in practical operation often due to the combined floodgate strength of disconnecting link not
Foot, causes contact to be incorporated into not in place, the contact one-side contact of disconnecting link tilts fingertip, and contact area, which substantially reduces, to be caused in operation
Heating of contact is burnt；And fingertip spring both sides force unbalance, long-play accelerate spring fatigue aging, shorten and use
Service life.
To ensure the good admittance of contact, breaking-closing operating need to be often repeated in construction personnel, and utilizes the works such as insulating bar
Tool top pressure, percussion make two conductive arms in line.Repeatedly divide-shut brake, hammer action aggravated indirectly support arm and contact deformation,
Offset or even the support insulator of damage disconnecting switch；Particularly the chucking power of static contact spring pressuring plate is entirely from spring
Pressure, the increase of divide-shut brake number cause the physical imperfections such as spring aging, contact deformation, clamping opening abrasion, caused contact area
The phenomenon that reduction, loose contact, happens occasionally, and hidden danger is brought to the safe operation of power grid.
