Abstract
The invention relates to a disconnecting switch moving contact disassembling tool. According to the disassembling tool, a cover is arranged on the upper part of a cylindrical contact finger and is movably connected with a sleeve; a handle is arranged on the sleeve; the diameter of the inner wall of the cylindrical contact finger is matched with the diameter of the outer wall of the moving contact. The disconnecting switch moving contact disassembling operation is safely, easily and conveniently finished, the working efficiency is improved, a silver plating layer on the moving contact is not damaged, the contact resistance between the disconnecting switch moving contact and a front conductive arm contact part is qualified, the operation is simple and convenient, the operating difficulty is reduced, time and labor are saved, and the manufacturing process is greatly improved.
Description
Technical field
The present invention relates to a kind of power equipment dismantling device, relate in particular to a kind of isolating switch moving contact dismantling device, be 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.
Summary of the invention
The present invention is directed to above-mentioned problems of the prior art, a kind of isolating switch moving contact dismantling device is provided, solved the problem of isolating switch moving contact dismounting difficulty in prior art.
Technical scheme of the present invention 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.
Advantageous effect of the present invention is as follows:
1, the contact portion of the present invention 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 guarantee 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.

Embodiment
Referring to accompanying drawing, in conjunction with specific embodiments, describe concrete structure of the present invention 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 present invention 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.
