Description
Technical field
The present invention relates to power industry aid technical field, be specifically related to a kind of portable transformer and transfer the files specific purpose tool.
Background technology
The general transformator said is transferred the files, transferring the files all referring to step-down transformer, and what regulate is the coil of primary side, because the coil turn of secondary side is less, current ratio primary side in coil much bigger, therefore general transformator is all that design regulates the coil turn of primary side to change secondary side voltage, is carry out corresponding gear adjustment by the device of transferring the files that primary side inlet wire wiring pile and secondary side outlet wiring pile are middle outside transformator.
Tradition S7, S9, S11 type distribution transformer method of transferring the files is first the disconnection of charged each side, transformator to be stopped transport; after primary side and secondary side discharge respectively; after carrying out the related security such as ground connection; open the unit protection cover of transferring the files in the middle of primary side inlet wire wiring pile and secondary side outlet wiring pile; use adjustable wrench slowly to rotate shunting switch top and carries out being transferred to relevant position, then remove safety measure, power transmission is transported again.
But S7, S9, S11 type distribution transformer height piling and low piling just seem that space is too small at the beginning of design, and device of transferring the files is unconventional regular hexagon shape, but very thin abnormity nut, artificial use adjustable wrench can not be put to good use when transferring the files flexibly, easily encounters again wiring pile and supports porcelain vase；And adjustable wrench to transfer the files be device top of transferring the files, easily burn inside transformer coil after often adjusting not in place, transformator length conduction time.More cannot use box spanner.Additionally transformator is often placed in open air, and device of transferring the files is easy to corrosion and specification is diminished, and the originally adjustable spanner determining jaw cannot re-use.
Summary of the invention
It is an object of the invention to provide a kind of portable transformer to transfer the files specific purpose tool, S7, S9, S11 type distribution transformer is quickly transferred the files, process S7, S9, S11 type distribution transformer and transfer the files screw leakage of oil situation.
For this, the technical solution used in the present invention is:
A kind of portable transformer is transferred the files specific purpose tool, including the plate body that gabarit is L-shaped, described plate body includes horizontal segment and vertical section, it is characterized in that: the middle part of horizontal segment is arranged can hold S7, S9, the notch that S11 type distribution transformer gear shifting mechanism inserts, horizontal segment is divided into the stiff lip of left stiff lip and the right side by notch, right stiff lip offers the rectangular channel being opened on plane, right stiff lip offers the rectangular opening communicated with rectangular channel on the side of notch, right stiff lip offers the screwed hole communicated with rectangular channel towards end face, first wedge is set in rectangular channel, be connected as a single entity with the first wedge and with the right angle hexahedron of rectangular opening interference fits or matched in clearance, in notch, a movable lip is affixed with the end face that right angle hexahedron stretches out rectangular opening；Also setting up the second wedge that the inclined-plane with the first wedge coordinates in rectangular channel, hexagonal jackscrew in coordinating in screwed hole, the top of jackscrew stretches in the blind hole that the second wedge is arranged, and jackscrew can rotate relative to the second wedge but can not horizontal displacement.
Further, fill grease in rectangular channel and pass through cover plate for sealing.
Further, vertical section arranges afterburning through hole near top.
Further, horizontal segment and vertical section increase arrange reinforcement.
Compared with prior art, the present invention can be conveniently carried out work of transferring the files in very narrow short space, and by the fine setting of movable lip, be suitable for the transformator of different size, and remain to reliably work after device corrosion of transferring the files.

Detailed description of the invention
nullReferring to Fig. 1-4.，A kind of portable transformer is transferred the files specific purpose tool，Including the plate body that gabarit is L-shaped，Described plate body includes horizontal segment 1 and vertical section 2，The middle part of horizontal segment is arranged can hold S7、S9、The notch 11 that S11 type distribution transformer gear shifting mechanism inserts，Horizontal segment is divided into the stiff lip 13 of left stiff lip 12 and the right side by notch 11，Right stiff lip offers the rectangular channel 131 being opened on plane，Right stiff lip offers the rectangular opening 138 communicated with rectangular channel on the side of notch，Right stiff lip offers the screwed hole 135 communicated with rectangular channel towards end face，First wedge 132 is set in rectangular channel，Be connected as a single entity with the first wedge and with the right angle hexahedron 136 of rectangular opening 138 interference fits or matched in clearance，In notch, a movable lip 3 is affixed with the end face that right angle hexahedron 136 stretches out rectangular opening；The second wedge 133 that the inclined-plane with the first wedge coordinates is also set up in rectangular channel, hexagonal jackscrew 134 in coordinating in screwed hole 135, the top of jackscrew 134 stretches in the blind hole that the second wedge 133 is arranged, and jackscrew can rotate relative to the second wedge but can not horizontal displacement.Fill grease in rectangular channel 131 and sealed by cover plate 137.Vertical section 2 arranges afterburning through hole 21 near top, when occurring that the situations such as gear shifting mechanism gets rusty adjust motionless gear, conveniently uses lever principle to be inserted in the instruments such as small-sized adjustable wrench or iron pipe and borrows power to transfer the files.Horizontal segment 1 and vertical section 2 increase arrange reinforcement 4, increase intensity.
During use, when the size of gear shifting mechanism is not mated with the size of jaw, stretch into inner hexagon spanner, jackscrew 134 is rotated in screwed hole 135, the rotation of jackscrew 134 drives the second wedge 133 to move forward and backward in rectangular channel, then the first wedge can drive right angle hexahedron 136 left and right displacement in rectangular opening 138, and drive activity lip 3 left and right displacement is thus adapting to the size of gear shifting mechanism.
