Description
Technical field
The utility model relates to machining tools art, particularly a kind of oil immersion-type distribution transformer shunting switch removal tool special.
Background technology
In Rural Power Distribution Network, oil immersion-type distribution transformer uses extensively, and distribution transformer often occurs oil impregnate, oil leakage fault because shunting switch loosens or oil seat gasket is aging, and maintenance process need be dismantled or fastening shunting switch nut, there is following problem:
1, between distribution transformer high-low pressure porcelain bushing shell and shunting switch, installation dimension is compact, common open-end wrench cannot use, ordinary cartridge spanner does not have so large size, screwdriver can only be used to withstand on nut edges and corners when dismounting or fastening shunting switch, beat screwdriver with iron hammer to carry out, waste time and energy.
2, unload or fastening shunting switch nut by the mode that iron hammer beats screwdriver, dynamics is difficult to control, and often occurs dismantling nut or fastening situation not in place, causes distribution transformer oil impregnate, oil leakage fault not to be keeped in repair timely and effectively.
3, dismantle or fastening shunting switch nut by the mode that iron hammer beats screwdriver, due to screwdriver and shunting switch nut contact surface less, easily cause shunting switch nut corner angle to damage, cause dismantling shunting switch.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of oil immersion-type distribution transformer shunting switch removal tool special, radiator fan and cooling pad body removably connect, be convenient to clear up radiator fan, to solve the above-mentioned multinomial defect caused in prior art.
For achieving the above object, the utility model provides following technical scheme: a kind of oil immersion-type distribution transformer shunting switch removal tool special, comprise afterburning handle, extension rod, sleeve, snap ring, it is characterized in that: described extracting tool comprises sleeve and snap ring, extracting tool bottom is provided with snap ring, snap ring adopts the coating steel pipe of Φ 65 ㎜ to be made, the groove with two parallel surfaces is provided with bottom snap ring, and snap ring groove parallel surface distance equals the flat square chi cun of the nut of shunting switch, snap ring top is provided with Φ 65 ㎜ sleeve, sleeve is made by coating steel pipe, cover tube length 40mm to 80 ㎜, upper cartridge is by being welded to connect extension rod, extension rod adopts Φ 32 ㎜ coating steel pipe to make, and long 180mm to 220 ㎜ of extension rod, the extension rod other end is by being welded to connect afterburning handle, afterburning handle is manufactured by Φ 16 ㎜ cylindrical steel, and long 280mm to 320 ㎜ of afterburning handle.
Preferably, described afterburning handle, extension rod, sleeve, snap ring are by T8 steel making.
Preferably, the described snap ring bottom groove degree of depth is between 8 ㎜ to 12 ㎜.
Preferably, the axial line of described extension rod, sleeve and snap ring is all on same straight line.
Preferably, the described center of afterburning handle and the upper end of extension rod are by being welded together.
The beneficial effect of above technical scheme is adopted to be: this oil immersion-type distribution transformer shunting switch removal tool special can be dismantled oil immersion-type distribution transformer shunting switch, by extension rod and sleeve, solve the problem that high-low pressure porcelain bushing shell and shunting switch spaces compact cannot use spanner, firmly only need originally exerted oneself 1/5th, the average used time of dismounting and fastening shunting switch shortens to 2-3 minute by original 20-30 minute, substantially reduce distribution transformer maintenance time, decrease shunting switch nut and damage probability, oil immersion-type distribution transformer shunting switch oil impregnate can be processed efficiently more in time, oil leakage fault.
