Abstract
The utility model provides a transformer tapping switch adapter of transferring files, includes the adapter, and the first half of adapter is equipped with first switching part, and the latter half is equipped with second switching part, first switching part is equipped with the bayonet lock for columniform switching groove at cylindrical switching inslot, second switching part is the switching groove of positive quadrangular type. The utility model provides a transformer tapping switch adapter of transferring files passes through the adapter with the power -driven rotation device and drives the voltage regulating switch rotation.
Description
Technical field
The utility model relates to transformer technology FIELD OF THE INVENTIONThe, is specifically related to a kind of sub-connecting switch of transformer and transfers the files adapter.
Background technology
Transformer test project is many, and the interruption maintenance activity duration is long, reduces power supply reliability.35kV transformer station mostly is single supply, cannot carry out electronic operation of transferring the files during main transformer interruption maintenance, needs hand motor bearings to make tapping switch gear-shifting mechanism reach certain energy and could drive stored energy mechanism action of transferring the files.When 110kV and above main transformer interruption maintenance, relaying protection specialty needs to overhaul the control device of tap changer, can not realize electronic operation of transferring the files.
Transformer test mainly adopts the hand mode of manpower to carry out gear shifting operation to tap changer.110kV main transformer on-load voltage regulating switch gear reaches 17 grades, and often conversion one grade need shake motor 33 circle left and right.When continuing hand operation, shake overlong time can cause arm strength not enough, causes swinging handle very easily to skid off draw-in groove, not only extends the activity duration of transferring the files, also result in shunting switch stored energy mechanism unbalance stress, also may make injury to personnel.
The shake of some transformers tap changer draw-in groove excessive height manpower is transferred the files, and speed is slow, and efficiency is low, poor stability.
Utility model content
Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, provides a kind of sub-connecting switch of transformer to transfer the files adapter, drives tap changer to rotate with electric rotary body by adapter.
To achieve these goals, the technical solution of the utility model is: a kind of sub-connecting switch of transformer is transferred the files adapter, and comprise adapter, the first half of adapter is provided with the first changeover section, and the latter half is provided with the second changeover section; Described first changeover section is columniform switching groove, in cylindrical switching groove, be provided with bayonet lock; Described second changeover section is the switching groove of four-prism type.
Be provided with magnetic stripe in described second changeover section, make adapter be adsorbed on tumbler, prevent adapter from coming off.
The size of described first changeover section is identical with the size of tap changer.
Described adapter is that steel material is made, and adds mechanical strength, meets the requirement that maintenance uses.
Adopt said structure, the utility model has the following advantages:
1, easy to carry, install, dismantle flexibly, reliable and stable in rotation process;
2, singlely can operate, what highly versatile was different transfer the files, and device all can mate this model adapter.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the left view of adapter;
Fig. 3 is the right view of adapter;
Fig. 4 is the schematic perspective view of adapter;
Fig. 5 is tap changer structural representation;
In figure: adapter 1, first changeover section 2, second changeover section 3, bayonet lock 4, tap changer draw-in groove 5.
Embodiment
As shown in Figures 1 to 4, a kind of sub-connecting switch of transformer is transferred the files adapter, and comprise adapter 1, the first half of adapter (1) is provided with the first changeover section 2, and the latter half is provided with the second changeover section 3; Described first changeover section 2 is columniform switching groove, in cylindrical switching groove, be provided with bayonet lock 4; Described second changeover section 3 is the switching groove of four-prism type.
Be provided with magnetic stripe in described second changeover section 3, make adapter 1 be adsorbed on tumbler, prevent adapter de-1 from falling.
The size of described first changeover section 2 is identical with the size of tap changer.
Described adapter 1 is made for steel material, adds mechanical strength, meets the requirement that maintenance uses.
During use, the first changeover section 2 is inserted tap changer, make bayonet lock 4 insert tap changer draw-in groove 5, then electric rotary body is inserted the second changeover section 3, thus drive tap changer to rotate.
