Abstract
The utility model discloses a distribution transformer off circuit tap changer specialized tool, including the connecting rod, the front end of connecting rod sets up the spanner, the spanner include that the front end has a cylindrical sleeve pipe of acceping the chamber, set up the jack catch that the symmetry is stretched out forward in sheathed tube both sides. The cylindrical chamber of acceping can hold distribution transformer off circuit tap changer outstanding stand and locating detent, and both sides set up jack catch card that the symmetry stretches out forward on the breach of cushion gland nut both sides, and the connecting rod makes operating handle be higher than height, the low pressure tower that sets up around the tapping switch, does not receive the influence of height, low pressure tower, and cushion gland nut can dismantle very conveniently or screw. Need not the transformer oil drain, tear open, work such as dress, only need not only to save time but also laborsaving with three minutes.
Description
Technical field
The utility model belongs to electric power tool, especially a kind of distribution transformer off circuit tap changer specific purpose tool.
Background technology
In distribution transformer service work, often run into the rubber cushion that distribution transformer shunting switch rubber cushion loosens in transportation or circumstance of temperature difference causes and loosen the situation such as oil impregnate, leakage of oil.As need service work be carried out, with common wrench and pipe wrench carry out shunting switch fastening time, cannot operate at all.Main cause is that sub-connecting switch of transformer distance high and low pressure tower is too near, and need to drain the oil to shunting switch, high and low pressure tower of dismantling just can carry out fastening shunting switch, and the fastening work carrying out a transformer needs two and one-half-hours used time.
Summary of the invention
The purpose of this utility model is to overcome prior art Problems existing, devises the distribution transformer off circuit tap changer specific purpose tool that a kind of structure is simple, easy to operate, operating efficiency is high.
The purpose of this utility model is achieved in that a kind of distribution transformer off circuit tap changer specific purpose tool, comprise connecting rod, the front end of connecting rod arranges spanner, it is characterized in that: described spanner comprises the sleeve pipe that there is cylindrical host cavity front end, the symmetrical claw stretched out forward is set in the both sides of sleeve pipe.
Further, be fixedly connected with between connecting rod with spanner.
Further, be connected between connecting rod with spanner by prismatic convex-concave interface activity, the rear end of spanner is set to prismatic groove, and the front end correspondence of connecting rod arranges prismatic projection; Or the rear end of spanner is set to prismatic projection, the front end correspondence of connecting rod arranges prismatic groove.
Further, the rear end of connecting rod arranges fixed handle.
Further, the rear end of connecting rod arranges flexible handle, and described handle is yi word pattern handle, and the tail end of connecting rod is arranged can through the handle through hole of yi word pattern handle.
Further, the rear end of connecting rod arranges flexible handle, described handle is " L " type handle, or ratchet spanner, the rear end of connecting rod is set to prismatic groove, the front end of " L " type handle or ratchet spanner arranges prismatic projection, or the rear end of connecting rod is set to prismatic projection, and the front end of " L " type handle or ratchet spanner arranges prismatic groove.
The utility model compared to the prior art its advantage is:
Spanner of the present utility model comprises the sleeve pipe that there is cylindrical host cavity front end, arranges the symmetrical claw stretched out forward in the both sides of sleeve pipe.Cylindrical host cavity can hold the outstanding column of distribution transformer off circuit tap changer and locating detent, both sides arrange the symmetrical claw stretched out forward and are stuck on the breach of rubber cushion clamp nut both sides, connecting rod makes operating grip higher than the high and low pressure tower arranged around shunting switch, not by the impact of high and low pressure tower, can dismantle or screw rubber cushion clamp nut easily.Without the need to transformer is drained the oil, the work such as demolition, installation, only with three minutes, not only need save time but also laborsaving.In addition, its structure is simple, easy to operate, operating efficiency is high, can as distribution transformer matched special purpose tools.
