Abstract
The utility model relates to an isolating switch moving contact disassembly tool. Structurally, a pressing cover is arranged on the upper portion of a cylindrical contact finger and is movably connected to a sleeve, and the sleeve is provided with a handle; the diameter of the inner wall of the cylindrical contact finger matches with that of the outer wall of a moving contact. The tool is capable of disassembling the isolating switch moving contact safely, easily and conveniently, operating efficiency is improved, the slivering layer of the contact is protected from being damaged, the contacting resistance of the contacting portion of the isolating switch moving contact and a front conductive arm is qualified, operation is simple, the operation difficulty is reduced, time and labor are saved, and the manufacturing process is improved greatly.
Description
Technical field
The utility model relates to a kind of power equipment dismantling device, relates in particular to a kind of isolating switch moving contact dismantling device, is particularly useful for flat high GW17B-252 type isolating switch moving contact dismounting.
Background technology
Isolating switch is higher in electric power system utilization rate at present, when substation equipment maintenance and repair practical operation, single-phase isolating switch need to be decomposed, and after checking, cleaning, re-assemblies again, qualified by producer's requirement standard debug.But when isolating switch decomposes front conductive arm, the moving contact of front end is difficult to dismounting, and twists and tightly very easily do not cause contact resistance defective after installing, if on-the-spot operational outfit consequence is very serious, will cause contact overheated, scaling loss when serious.
The main cause of isolating switch moving contact dismounting difficulty is, moving contact smooth surface and have silver coating is damaged silver coating with the direct dismounting of box spanner meeting.
Utility model content
The utility model, for above-mentioned problems of the prior art, provides a kind of isolating switch moving contact dismantling device, has solved the problem of isolating switch moving contact dismounting difficulty in prior art.
The technical solution of the utility model is as follows:
The top of cylindrical shape fingertip arranges gland, and gland is flexibly connected sleeve, and handle is set on sleeve; The inner diameter of described cylindrical shape fingertip and the outer diameter of moving contact match.
Described cylindrical shape fingertip is made up of end to end N shape sheet.
Between described gland and sleeve, be threaded connection.
Described gland is connected with disk, and disk is provided with two cylinders, and two cylinders are positioned on same diameter.
Two circular hole distances on distance between two described cylinders and moving arcing contact match.
The utility model has the advantages of as follows:
1, the contact portion of the utility model and moving contact has adopted plastics fingertip, avoids damaging while using the instruments such as other pipe wrench the defect of silver coating; Moving contact is connected more firm with front conductive arm, meets contact resistance requirement standard, eliminate this connecting portion because loose contact, the contact resistance overheated hidden danger causing that exceeds standard.
2, easy and simple to handle, reduced operation easier, and can ensure repair quality and maintenance craft.
3, when dismounting moving contact, convenient and swift, greatly shorten the repair time, increase work efficiency, time saving and energy saving.

In figure: 1, fingertip, 2, gland, 3, sleeve, 4, handle, 5, disk, 6, cylinder, 7, moving contact.
Embodiment
Referring to accompanying drawing, in conjunction with specific embodiments, describe concrete structure of the present utility model in detail.
Embodiment
As Figure 1-4, four N shape sheets join end to end and form cylindrical shape fingertip 1, and the outer diameter of the inner diameter of cylindrical shape fingertip 1 and moving contact 7 matches; The top of cylindrical shape fingertip arranges gland 2, and gland 2 is flexibly connected aluminium alloy sleeve barrel 3 by screw thread, and the both sides of sleeve 3 arrange respectively handle 4; Described gland 2 is connected with disk 5 by hook link, and disk 5 is provided with 6, two cylinders 6 of two cylinders and is positioned on same diameter; Two circular hole distances on distance between two described cylinders 6 and moving arcing contact match.
Disk is of a size of, thickness 20mm, diameter 260 mm; High 15 mm of cylinder, body diameter 0.8 mm, two cylinder spacing 160 mm.Plastics fingertip is of a size of, height 100 mm, diameter 220 mm; The height 20mm of aluminium alloy sleeve barrel, diameter 250 mm.
The utility model is specially adapted to the flat high GW17B-252 type isolating switch moving contact of dismounting; Wherein disk cylinder is suitable for the moving arcing contact part in moving contact, and two cylinders on disk are inserted in the circular hole on moving arcing contact, pulls spanner and can pull down moving arcing contact part; Cylindrical shape fingertip is suitable for the main part of the flat high GW17B-252 type isolating switch moving contact of dismounting, and concrete operation step is as follows: unclamp gland, will be placed on turn 1 to 2 button in aluminium alloy sleeve barrel with the gland of plastics fingertip; The fingertip sleeve set combining, in moving contact main part, is tightened to gland, make plastics fingertip hold the main part of moving contact tightly; Two handles pulling on sleeve rotate counterclockwise, and fingertip sleeve is pulled down together with moving contact; Unclamp gland, fingertip sleeve and moving contact main body are separated, complete the dismounting of moving contact main part.When installation, carry out in reverse order.
